andy van sumeren lunch and learn June 19, 2020:

CHEPS hosted its 5th virtual Lunch and Learn of summer 2020 on June 19th. The invited speaker was Andy Van Sumeren, a University of Michigan alum. Andy spoke on his experience working for GE Healthcare as a lean manufacturing manager during the COVID-19 ventilator crisis. He then touched on his new role at GE that is focused on the commercial side of the business. Throughout the talk as well as afterward current CHEPS students were given the opportunity to ask Andy numerous questions about his experiences working as a part of the COVID relief group.

Andy graduated with a bachelor’s degree in Industrial and Operations Engineering in 2007. He has been working for GE healthcare in a variety of roles and locations since 2005 beginning with internships while he was completing his IOE degree. After graduation, he started as a manufacturing process engineer and then moved into various managerial roles within lean manufacturing. His current role is Director of Operational Excellence which is a newer role within GE.

Andy focused much of his talk on his experience with the COVID-19 fight at GE’s Madison, WI facility. He described it as two months of “crazy hard work”. Their goal was to increase the production output of ventilators by three-fold. He described every day as a different safety and emotional experience. He shared his IOE mindset during the project and how he used lean thinking to triple the output of ventilators in such a short time frame. He provided several examples of the tools he used for his team including a Fishbone diagram that explained how a ventilator was put together as well as a Production Process at a Glance. This showed all of the steps that go into making a ventilator including anything of value that ensures quality. Andy also did a great job addressing challenges that he and his team faced both emotionally and technically.

Andy finished up his talk briefly explaining his new role within GE as the Director of Operational Excellence. This role is focused on taking lean methodologies and transforming them into how to sell, service, and contract products on the commercial side of GE Healthcare. He is working to help GE Healthcare switch from being a reactive service provider to being a proactive service provider for their customers.

Throughout the presentation and at the end, CHEPS students asked very thoughtful, engaging questions. Students were especially interested to learn about how COVID-19 impacted the culture at GE and what the hardest part of the relief effort was. Andy said that the culture shift was difficult as people were initially very scared of the unknowns resulting from the virus. We are very grateful to Andy for taking the time to talk to us about his work and answer our questions.

CHEPS hosted its fourth virtual Lunch and Learn of Summer 2020 on Thursday, June 11. The invited speaker was Dr. Ron Golan, an endourology fellow at New York Presbyterian- CUMC. Dr. Golan spoke about the importance of Ergonomics in surgical procedures with a focus on urological surgeries. He went over the important ergonomic considerations, risks involved, and prevention of injuries in operating rooms. The talk ended with current CHEPS students utilizing this opportunity to ask questions about Dr. Golan’s research and other related topics.

After finishing his B.S. from The College of New Jersey, Dr. Golan went to medical school at the University of Pennsylvania School of Medicine. He spent the next six years doing a urology residency at Weill Cornell Medicine. In August 2019, he joined Columbia University Irving Medical Center as an endourology fellow and has been there since.

The session started with Dr. Golan introducing us to surgical ergonomics and its goal to enhance the safety, effectiveness, and quality of life while decreasing the risk of workplace injury. Then, he discussed the role of Knoll Inc. in helping to build the improved hospital design and the challenges that are faced in healthcare design such as 24/7 operation and a wide range of physical activities. From his research and literature review in urology ergonomics, Dr. Golan found out that for the most part there is no formal training for surgeons to learn about the ergonomic effects of doing surgery and this is limited not just to urology but to other departments as well. His research shows that on an average 30-40% urologists have none to little knowledge about their ergonomics while they are in OR; the ramifications of which are seen in terms of surgeons complaining about stiffness in shoulder, neck, back, thumb and other related problems.

Dr. Golan then discussed the different types of surgeries performed in urology as well as robotic surgeries with their pros and cons. We learned about room/patient positioning in urological procedures and important considerations such as room layout, instruments’ availability, and performance optimization factors such as distractions from temperature i.e. when the lead surgeon is wearing multiple gowns and feels warmer and wants the operating room to be colder, but has to keep in mind that scrub nurses and remaining staff aren’t as heavily clothed as them, so the temperature has to be a bit higher than the surgeon’s liking. Dr. Golan also talked about the effect of the weight of flexible ureteroscopes and risk factors for surgeon injuries. He also pointed out that 86% of urology surgeons have musculoskeletal discomfort attributed to operating. Later in the discussion, Dr. Golan gave an excellent pictorial presentation of correct and incorrect postures of surgeons in the operating rooms for both normal surgeries as well as robotic surgeries. He also presented the work which suggests ways to prevent the work-related injuries of surgeons in urology and a preventive program for work-related musculoskeletal disorders.

Dr. Golan also focused on ways CHEPS can be of help by working on areas like improvement of the workflow by reducing bottlenecking, reducing redundancy, looking at the durability of equipment, etc. In Q&A, Dr. Golan answered a few interesting questions such as what happens if the focus of surgeons is divided between ergonomics and actual surgery and if are there any related studies that point out such effects. We had a very interesting question from Dean (Dr. Golan’s brother), asking about issues that left-handers face while training as surgeons. To this Dr. Golan, a left-hander himself, answered that on account of most people being right-handed, we are taught to practice most of the procedures with the right hand as the leading hand (Go Left-handers!). We are very grateful to Dr. Golan for taking time out of his busy schedule to meet us virtually and sharing his firsthand experience of the hospital and operating room environment. We look forward to having him back sometime in the future for another interesting talk.

CHEPS hosted its third virtual Lunch & Learn on Friday, June 5. The invited speaker was Hass Abbas, a University of Michigan graduate and CHEPS alum. Hass spoke of his CHEPS experience, life as a nurse, and COVID-19. Afterward, current CHEPS students were given the opportunity to ask Hass questions about his experiences.

Hass completed his undergraduate degree at the School of Nursing here at UofM. Hass began working at CHEPS the summer after his freshman year and worked there for 4 years until the summer after he graduated in 2017. Hass discussed working on the “Asthma Project” as well as Surgical Instruments. Hass was able to attend the Society for Health Systems Conference and thanks CHEPS for the friends and sense of community it gave him. Through CHEPS, Hass learned how to look at his work from a more holistic perspective.

After graduation, Hass worked in the Cardiovascular ICU at Johns Hopkins for two years as an RN. Afterward, he moved back to Detroit to work in the Cardiovascular ICU at the Detroit Medical Center. Hass talked about his day-to-day life as a nurse. He explained the intensity of the ICU as well as the amount of autonomy he has in his job. Hass also discussed how important teamwork is within his job and the healthcare system as a whole, especially during the height of COVID-19. Hass explained how he worked 16 shifts in a row during the peak of the pandemic and how unpredictable and crazy it truly was.

In the Q&A, Hass answered questions about his toughest CHEPS experience, how he deals with anxiety in a high-stress job, and how he is able to stay up to date on any new policies and procedures relating to COVID-19. He emphasized how important it is to work as a team with his coworkers and also how difficult it can be to make change in a hospital. We are very grateful for Hass taking the time to talk to us about his work and answer our questions.

med school lunch and learn June 4, 2020:

On Thursday, June 4th, CHEPS hosted a student panel with CHEPS alumni including Roshun Sankaran, Lauren Hirth, Bassel Salka, Anna Munaco, and Erkin Otles. This event took place at CHEPS weekly student-led Lunch & Learn on Zoom. The panel addressed what sort of opportunities students should take and seek out to prepare for medical school, MCAT tips and strategies, gap year plans, other medical school application tips and tricks!

Roshun Sankaran, a student who joined CHEPS during the Summer 2014 semester, joined us for this panel. He is currently a second-year medical student at the University of Michigan Medical School. Roshun studied Neuroscience and applied statistics during his undergraduate years at CHEPS and got a Master’s in Public Health during his gap year.

After both having taken a gap year after concluding their engineering and pre-med undergraduate careers at U of M, Lauren Hirth and Bassel Salka, both plan on attending the University of Michigan Medical School, joined CHEPS during their sophomore year. Lauren spent her gap year in a Post-Bachelor program at the National Institute of Health while Bassel spent his gap year at the Johns Hopkins Applied Physics Lab.

Anna Munaco is currently going into her M4 year at Michigan, applying to residencies in the fall. She joined CHEPS during the Winter 2015 semester as an IOE student but pivoted her focus toward medicine during her undergraduate career.

Finally, Erkin Otles, an MD Ph.D. student researching in the field of IOE, joined us and expanded on the interconnection between research and medical school. While not a Michigan alum (yet!), Erkin graduated from the University of Wisconsin with the intent of working as an engineer. After working at Epic for a couple of years, he landed here at U of M.

Thank you to the group for their excellent insights into all aspects of medical school!

CHEPS hosted its second virtual Lunch & Learn on Friday, May 29. The invited speaker was Bill Zhang, a University of Michigan graduate and a CHEPS alum. Bill spoke of his academic and professional journey beginning from his undergraduate degree and leading into his career today. Afterward, current CHEPS students were given the opportunity to ask Bill questions about his day-to-day work duties and advice about pursuing an occupation in healthcare engineering.

Bill completed his undergraduate degree in industrial engineering at a small college in Massachusetts. After graduation, he worked at the VA hospital in Boston, implementing several logistics projects, such as linen distribution for supply chain. Additionally, Bill was a data analytics consultant for hospitals for 2 years. Bill described to us his growing interest in healthcare public policy throughout his experiences. He desired to learn more and so, he applied to the University of Michigan School of Public Health and the Department of Industrial and Operations Engineering for a dual-degree. He was accepted and began his master’s program. As a part of the program, he interned at the Cleveland Clinic. During his time as a graduate student, he also worked at CHEPS where he made several great friends and still has many fond memories! His favorite memories are the pre-CHEPS symposium happy hour dinner with alumni and the Christmas party!

After finishing his graduate education, Bill relocated to California where he currently works at Kaiser Medical Center. He is accountable for the budget, patient satisfaction, equipment, and strategic planning of the 12 departments. Bill has taken the lead on several COVID-19 operations. A critical system he developed for the hospital was a drive-thru testing location where individuals suspected of contracting the virus can be tested in their cars. He also designed a sustainable entry point check-in; healthcare workers check the temperature, read through the symptoms checklist, and distribute face masks to patients. Bill is working to organize a flu shot drive-thru and other facility modifications including a one-way patient traffic flow, implementing 6ft distancing, and reducing waiting room capacities. His work reduces patient exposure to COVID and other harmful sicknesses.

In the Q&A session, Bill advised students seeking a career in healthcare engineering to develop their data analytics skills. Visualizing and communicating information to those who are not familiar with the data is very important. Furthermore, the ability to work in an interdisciplinary team is a valued skill in the workplace. We’re very grateful for Bill and the time he took to answer our questions and share with us about his work!

On Friday, May 22, CHEPS had its first virtual Lunch & Learn. Friend-of-CHEPS and Industrial and Operations Engineering alum Mark Van Sumeren was generous enough to share with all of us some of his work on the existing COVID-19 situation. Mark is Managing Director of Health Industry Advisor LLC, which offers health systems as well as medical device and healthcare suppliers critical thinking and expertise to address challenges in the healthcare industry.

Mark acquainted us with his work on “an analytical perspective on the virus progression.” He began by emphasizing the propagation of conflicting and misleading information in the population and countered many adversities that are caused due to false information. He and his collaborators have come up with an approximately 150-page dashboard that contains credible information about the virus progression, its existing state, and some of the projections that could be made based on the existing data. This dashboard covers data derived from across 30 countries, 50 states, and 2,908 counties & municipalities. It contains information about the number of tests being conducted, the number of active cases, as well as the number of deaths and recovered patients. He also presented some of the statistical data based on counts in different locations such as Rhode Island, Maryland, and Michigan. He also touched on the data from the CDC on whether the states could be opened soon or not.

During a Q&A, Mark also shared his perspective on some of the questions asked about the pattern of the projected second wave, were hospitals really pushed to their limits, measuring of the data, and monitoring of the active cases, etc. He provided some good analysis and it was a great time getting an opportunity to learn things from him. We hope to see him again in the future and have him share more of his valuable insight with us.

prenatal team May 8, 2020:

Dr. Alex Friedman Peahl, a CHEPS collaborator, has been doing valuable work on delivering prenatal care during the COVID-19 pandemic. She was recently featured on Good Morning America discussing how to “keep moms and babies safe before, during, and after pregnancy.” As part of keeping patients safe during the pandemic, Dr. Peahl and her collaborators have reduced in-person prenatal visits and replaced some of those visits with virtual prenatal care. She and her team have also started a new online pregnancy support program, Stay Home, Stay Connected: a unique collaboration between the department of Ob/Gyn, Psychiatry, and Social Work, to give moms additional support and peer mentorship.

For the past year, a CHEPS team has been working with Dr. Peahl on a project that also looks at prenatal appointment scheduling and how to best meet patient needs. The CHEPS team is helping Dr. Peahl with research focusing on a group of patients who delivered children over a one-year time frame. The group then follows the cohort’s pregnancies and postpartum care in order to define the cohort’s medical and social support. They look at factors such as comorbidities to determine medical needs and factors like social work consults and patient portal messages to determine their needed support. This information can then be used to ensure the healthcare services delivered match the patient’s needs by better understanding the number and type of appointments patients need.

“We helped Dr. Peahl with the COVID-19 related scheduling,” said Harini Pennathur, an Industrial and Operations undergraduate student and member of the CHEPS prenatal team. While their results on patient medical and social support were not ready to use in determining the number of virtual appointments during the pandemic, their groundwork in understanding scheduling informed prenatal care redesign during the pandemic. Harini said, “Our work is kind of intermingled with that work because we are working towards seeing how to make appointments virtual.” CHEPS students on the prenatal team for the winter and summer semesters of 2020 are: Jordan Goodman, Hannah Heberle-Rose, Amanda Naccarato, Harini Pennathur, and Nicholas Zacharek along with CHEPS Associate Director Amy Cohn and CHEPS staffer Julia Herzog Warner.

For all of their excellent work to make pregnant patients and their babies safer, Dr. Peahl and the CHEPS prenatal team are this week’s CHEPS Champions!

CHEPS Associate Director Amy Cohn is part of a team that recently shared initial results from their research looking at the use of heated high-flow nasal cannula (HHFNC) to treat patients with COVID-19 in acute hypoxemic respiratory failure. The team’s work may have long-term implications as far as how patients with COVID-19 are cared for.

Professor Cohn previously worked with members of this team when she was a committee member on then nursing Ph.D. student Emily Boltey’s defense. Dr. Boltey’s research focused on patients on mechanical ventilation in intensive care units, specifically looking at interprofessional teams. As a result, her committee included Professor Deena Kelly Costa from the Nursing School, Dr. Jack Iwashyna from Pulmonary Critical Care Medicine, and Professor Cohn from the College of Engineering.

Because they had worked together in the past, when Dr. Iwashyna decided to research a question related to ventilation, he knew where to turn. He approached Prof. Cohn explaining he wanted to better understand how the use of HHFNC impacts the aerosolization of COVID-19 which could be a cause of contagion for providers taking care of infectious patients.

Prof. Cohn was able to help facilitate the quick assembly of a group including Mechanical Engineering faculty with expertise in measuring aerosolization, Dr. Jim Cooke who runs the Michigan Medicine Simulation Center and is also a long-time Friend of CHEPS. They were joined by respiratory therapist Ric Eakin from Respiratory Care, Dr. Hallie Prescott from Pulmonary Critical Care Medicine, Prof. Jesse Capecelatro from Mechanical Engineering (ME), Prof. Margaret Woolridge from ME, and Prof. Andre Boehman from ME to do experiments to test aerosolization from HHFNC.

The team completed experiments in less than two weeks and posted a paper in less than six weeks from start to finish. Their research showed some surprising results. The paper, titled “Variation in Aerosol Production Across Oxygen Delivery Devices in Spontaneously Breathing Human Subjects” is now under peer review and is available to read online.

While the takeaways about aerosolization are notable, this research also shows the value of bringing together people from different backgrounds and areas of expertise to tackle a complex problem. “At a time where everyone is committed to solving an important problem, bringing together such a team can lead to high-impact results,” said Professor Cohn.

The team was able to share some important preliminary results based on their quick study, but the research project will go on well-past the immediate urgency of the spike in COVID-19 cases. They are currently working together on a grant proposal to do a more thorough and in-depth, conscientiously designed study.

wanty lunch and learn February 14, 2020:

Last Friday, February 14th and Valentine’s day, CHEPS students and faculty gathered together to hear from Doug Wanty during a Lunch and Learn. Doug brought a very interesting perspective to share about healthcare. His background is actually in clinical psychology and the beer distribution industry. Doug completed his Ph.D. in clinical psychology and his wife is a retired OBGYN nurse. Doug has been in the beer industry for quite some time and runs a beer distribution company, O & W, Inc.

Doug mentioned the similarities between optimizing administration and logistics within a hospital and his beer distribution business. As a small business owner who is involved in overseeing employee healthcare options, he was also able to give us unique insight into employer-provided health insurance. He touched on the quickly rising cost of health insurance and educated us on the healthcare insurance system. Doug also spoke of how hospitals and businesses differ. A business’s primary goal, as Doug mentioned, was to lower cost. A hospital’s main goal is not to find the cheapest method to complete something, but rather the safest and highest care option. It was a pleasure getting to know and learn from Doug, and we hope to have him and his wife come in again to speak with us more in the future!

INFORMS Exchange
February 1, 2020:

In the summer of 2017, members of the Institute for Operations Research and the Management Sciences (INFORMS) student chapter from Northwestern University came to Ann Arbor to meet with the University of Michigan INFORMS student chapter. The visit gave the two groups a chance to talk about how they run their chapters, their research, and more. CHEPS alum Moses Chan is now pursuing his Ph.D. at Northwestern and is their INFORMS president. He reached out to fellow CHEPSter Adam VanDeussen, who is outgoing Michigan INFORMS president about making another exchange happen. As a result, five members of the Michigan INFORMS chapter traveled to Northwestern this February to meet with members of the INFORMS chapter there.

“We spent the morning on research talks, so like various talks similar to conference presentations, just in a smaller group,” said Adam. “And in the afternoon we talked more about challenges our chapters were facing like ‘how do we hold events that are interesting and inclusive of undergrads?’ or ‘what kind of challenges do we have around funding?’ and things like that.”

The group also had a chance to enjoy a tour of Northwestern and have dinner together. There was even a mini-CHEPS reunion. Sarah Bach and Michelle Chen, also CHEPS alums now at Northwestern pursuing their Ph.D.s, also participated in the exchange event. The four CHEPSters had a great time catching up!

CHEPS alum Theodore Endresen recently stopped by CHEPS for a visit while on break from his master’s program in Management Science and Engineering at Tsinghua University. “Tsinghua is an excellent school,” he said. “It offered a unique opportunity to learn about aspects of industrial engineering that we’d learn here but with a specific focus on China. A lot of companies I would work for do business with China so that’s an interesting thing to have the opportunity to use later on.”

Many of his classes have semester-long projects. He said, “Working at CHEPS gave me a leg up on all of those, especially when you had to do a bunch of literature reviews and then formulating large models.”

Aside from his studies, Theodore has also had the opportunity to train with Tsinghua’s track team. He participated in track as a club sport while he was at the University of Michigan. He said track at Tsinghua is a different experience. “Over there, everyone’s a professional athlete on the team, except for me,” he explained. “We train at the national training center and that’s interesting. I’m a little out of place with like the Chinese Olympic team that’s also there.”

In addition to being a good way to make friends, Theodore said that participating in track has also been an excellent way to practice his Chinese. While he has a Chinese class once a week, the rest of his classes are in English. “If you want to actually learn Chinese, you have to self-study. So I self-study every day. But then I get to go meet with the track team. Going to meet with them is great practice because only one team member can speak English fluently so it’s a great way to practice my Chinese and I can help them with their English.”

ajaay January 17, 2020:

CHEPS alum Ajaay Chandrasekaran recently accepted a new position as a Software Engineer on the Advanced Driver Assistance System (ADAS) initiatives at Fiat Chrysler Automobiles (FCA) in Auburn Hills, MI. FCA, in collaboration with BMW Group, Intel, and Mobileye, is developing a state-of-the-art autonomous driving platform for global deployment. Ajaay, who graduated from the University of Michigan with his BS in Computer Science in 2017 and MSE in Electrical and Computer Engineering in 2018, is involved in the development of that platform.

“In my opinion, implementation of autonomous vehicle technologies is among the greatest technical challenges today, and I consider it to be a very exciting problem to tackle,” said Ajaay. He spent 2 years at CHEPS during his time at Michigan and has taken many of the things he learned here into his post-CHEPS career. “Though I no longer work in healthcare as I did at CHEPS, there are a lot of similarities in my work,” he said. “Having a background in computer science and algorithmic methods for robotics, I have to collaborate and interface with others from a wide variety of backgrounds, including mechanical engineering, electrical engineering, and automotive engineering. This is very similar to the environment at CHEPS where I had an opportunity to work with peers from a variety of fields, ranging from public health to operations engineering.”

And that’s not where the similarities to his work at CHEPS end. Ajaay said, “Another lesson that I carry with me from CHEPS is the ability to evaluate the impact of my work on the safety of users. At CHEPS, patient safety was an extremely important factor influencing my work, and I learned to practice great care for how my work impacts individual patients’ lives–either directly or indirectly. In the autonomous vehicle domain, I similarly recognize that my work has little room for error since human lives are directly on the line when individuals decide to trust an autonomous vehicle to take them from one place to another without an accident.”

state hospital January 15, 2020:

A CHEPS team has been awarded funding from the State of Michigan Department of Health and Human Services to understand how variability in staffing impacts patient care in the State Health System. The team consists of CHEPS Associate Director Amy Cohn and CHEPS students Jordan Goodman (Industrial and Operations Engineering Masters with a concentration in Healthcare Engineering & Patient Safety), DucMinh Ngo (Computer Science Undergraduate), Nikita Ramachandran (Public Health Masters), and Matt See (Chemistry Undergraduate). They are working closely with Dr. George Mellos, the lead psychiatrist and deputy director for the Behavioral Health and Developmental Disabilities Administration at the Michigan Department of Health and Human Services, as well as his excellent staff.

Understaffing at a state hospital leads to an increase in the potential risk of harm to both patients and caregivers. Harm to caregivers leads to increases in absenteeism which can spiral. The research team is looking at the impact of absenteeism on injury and how to staff state hospitals in a way that keeps both the patients and their caregivers safer. “We’re dealing with some of the state’s most vulnerable and in-need patients and so it’s incredibly rewarding to apply our engineering skills in such a direct way that’s going to help people,” said Professor Cohn.

December 11, 2019:

Current CHEPSter and IOE Ph.D. student Junhong Guo attended the 2019 Winter Simulation Conference (WSC) in National Harbor, Maryland from December 8 – 11. According to the conference website, “The 2019 conference seeks to highlight the latest simulation technologies for more accurately anticipating risks and for making more robust decisions in the face of uncertainty, ambiguity, and variability. These include methods for robust and accurate simulation modeling, analysis, and optimization. We also invite papers describing applications of simulation to risk management in a broad variety of domains, including healthcare, disaster response, power grids, construction, transportation, finance, cybersecurity, and more.”

Junhong presented a paper titled “Using Discrete-Event Simulation to Find Ways to Reduce Patient Wait Time in a Glaucoma Clinic.” The paper details a project collaborating with the glaucoma clinic at the Kellogg Eye Center at UM and it has been accepted to be published in the conference proceedings.

During the conference, Junhong got the chance to meet and talk with many researchers. He also attended several sessions to learn about how simulation can be applied to help address different problems in a variety of fields, e.g. evaluating different heuristics in terms of scheduling providers in a specialty clinic; how airplane separation rules impact the number of tactical resolution maneuvers required during air traffic control; the propagation of the flight delay caused by the buffers conservatively imposed by the air traffic controllers when the weather is calm but the vision is not good, and so on.

Junhong described the most exciting part of the conference for him saying, “I feel truly happy that I met my previous advisor at Cornell, Prof. Shane Henderson, during the conference. Shane also came to my talk to support me. He asked many great questions and provided me with many valuable comments, which would definitely help us further improve our work.”

December 9, 2019:

On December 9th, Dr. Amy Cohn and engineering students Hannah Strat, Daniel Cao, and Kristine Wang presented their work on “Addressing Multi-Criteria Objective Functions in Healthcare Provider Scheduling Projects” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Amy Cohn is the Associate Director of the Center for Healthcare Engineering and Patient Safety and a Thurnau Professor of Industrial and Operations Engineering at the University of Michigan. Hannah Strat is a Master’s student studying Industrial and Operations Engineering with a concentration in Healthcare Engineering and Patient Safety (HEPS) and completed her Bachelor’s degree in Chemical Engineering at the University of Michigan in 2018. Daniel Cao is an undergraduate studying Industrial and Operations Engineering and Kristine Wang is an undergraduate student studying Computer Science Engineering at the University of Michigan. Dr. Cohn and the student team collaborated directly with Dr. Krishnan Raghavendran who currently works as the Division Chief of Acute Care Surgery and a Professor of Surgery at Michigan Medicine. This collaborative project between engineers and clinicians centers around creating a scheduling template to allow for faster and easier creation of schedules for attending physicians in the Division of Acute Care Surgery at Michigan Medicine.

Dr. Raghavendran, unfortunately, was not able to attend the lecture due to four emergency surgery cases that required his attention, but the student team and Dr. Cohn presented the challenges and successes associated with creating an “optimal” schedule. The complexity of this problem stems from the lack of an objective function around which an optimization model can be constructed. As you can imagine, all physicians have competing priorities such as time-off requests for important family events, the balance of night-shift and day-shifts, and the number of weekend shifts that they are scheduled for. Other rules such as restrictions on how many consecutive night shifts and consecutive weeks attendings can work are crucial to avoid fatigue and maintain the health of healthcare providers. The balance of these rules and individual scheduling preferences makes for a difficult problem that the CHEPS Trauma team worked to solve. By defining several model constraints and frequently soliciting clinician feedback from Dr. Raghavendran, the team succeeded in creating a schedule that granted 108 of 110 time-off requests on day shift and 152 out of 182 assignments within the preferences outlined by physicians.

Dr. Cohn emphasized the importance of collaboration between engineers and healthcare providers to solve complex problems. Engineers and clinicians tend to have drastically different perspectives and priorities which can make communication difficult, however, both perspectives are crucial to allow for the best project outcomes. CHEPS was established on the philosophy of the importance of collaboration and the fantastic results on this and other projects demonstrate the value of clear communication.

We thank Dr. Cohn, Hannah, Daniel, and Kristine for their outstanding presentation and offering their unique perspective on the challenges and benefits of clinician collaboration.

stirling December 2, 2019:

On December 2nd, Dr. Leia Stirling presented her work on “Using Wearable Motion Sensors for Augmenting Occupational Therapy Assessment” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Stirling is an Associate Professor in Industrial and Operations Engineering at the University of Michigan. She previously worked as a postdoctoral researcher at Boston Children’s Hospital and Harvard Medical School, on the Advanced Technology Team at the Wyss Institute for Biologically Inspired Engineering, and as an Associate Professor at MIT before coming to U of M. Her research focuses on the use of wearable technologies to track human performance, mitigate injury risk, and assist clinicians and other experts in tracking patient health and progress.

During her lecture, Dr. Stirling outlined the benefits associated with the use of wearable sensors to track patient progress in occupational therapy clinics. One of the main challenges that occupational therapists face is determining whether a lack of patient progress is due to noncompliance, incorrect exercise technique, or inadequately prescribed therapy. With no way to monitor at-home behaviors, therapists must conduct assessments in clinic to determine if patients are doing exercises properly and trust that patients will be truthful about their level of compliance. The incorporation of wearable sensors would enable therapists to track and monitor patient progress much more accurately. The challenge with wearable sensors, however, is that raw sensor data can be very difficult to interpret and utilize for decision making. Dr. Stirling and her colleagues studied three qualification metrics associated with wearable inertial measurement units (IMU): coordination, static balance, and compensatory torso motion. These three studies were conducted healthy, aging, and stroke recovery patients respectively with the goal of creating models that are easy to interpret, display motion patterns, and can help augment decision making.

We thank Dr. Stirling for presenting her intriguing work and welcome her to the University of Michigan as a new faculty member.

bayram November 25, 2019:

On November 25th, Dr. Armagan Bayram presented her work on “Managing Virtual Appointments in Chronic Care” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Bayram is an assistant professor in the Department of Industrial and Manufacturing Systems Engineering at the University of Michigan- Dearborn. Her research centers around the development of stochastic models and solutions for resource allocation and appointment capacity in healthcare clinics. Her lecture focused on her work related to optimization of virtual and office appointment patient scheduling.

In recent years, the demand for virtual appointments that allow patients to see their physicians remotely has substantially increased. Virtual appointments allow patients to seek treatment and diagnoses from their physicians without physically traveling to the clinic. By 2020, it is expected that over 25 million virtual appointments will be conducted in the U.S with a projected growth of 10% each year. As this demand increases, questions about how to best schedule patients and achieve the best patient outcomes continue to intrigue researchers like Dr. Bayram. As such, Dr. Bayram and her colleagues have worked to design stochastic models centered around patient health status (how sick patients are) and needs (diagnosis or treatment). These models allow for quantification of the impact of virtual appointments on patient outcomes, the availability of office appointments for the sickest patients, and the number of return patient visits. Specifically, Dr. Bayram and her team sought to model the benefits of a myopic heuristic model in which the sickest patients receive office appointments versus the rotation heuristic model in which appointments are allocated equally. Through the use of these powerful models, we can better predict real-world outcomes and design a scheduling system to contribute to the best possible patient outcomes.

We thank Dr. Bayram for participating in our seminar series and for showing us the impact that virtual appointments can have on our future healthcare system.

cheps reunion November 15, 2019:

The Friday before our annual CHEPS Symposium, CHEPS alums, students, faculty, staff, and more gathered to enjoy dinner together at Conor O’Neill’s in downtown Ann Arbor. Alums returned from all over including Chicago, IL; Seattle, WA; and Laurel, MD. CHEPS has been around long enough now that not all of the alumni know one another but even those who hadn’t met before chatted like old friends. One of the highlights was seeing current students catch alumni up on the happenings at CHEPS and the progress made on some of our long-running projects. It’s always a pleasure bringing our alumni and students together. Donald Richardson and Bassel Salka, alums now working at the Johns Hopkins Applied Physics Laboratory, even held office hours in CHEPS on Monday, November 18th. They were able to give current students career and academic advice as well as insight on working at Johns Hopkins and some job and internship opportunities available there.

hirth November 15, 2019:

Lauren Hirth worked with CHEPS for three years as an undergraduate Biomedical Engineering student. After graduating in the spring of 2019, she started work at the National Institutes of Health. She recently checked in with an update about her work:

“I am currently working as a postbaccalaureate research fellow at the National Institutes of Health Clinical Center. Specifically, I work in the Functional and Applied Biomechanics Lab in the Rehabilitation Medicine Department. My main project is a longitudinal study with infants that are at risk of a cerebral palsy diagnosis. I am using both EEG and near-infrared light technologies to monitor brain activity during different motor tasks. I am really looking forward to learning more about the onset and development of motor tasks in this population and hope to help bridge the gap between engineering applications and clinical diagnoses and treatments. I have also worked to standardize and streamline a new pipeline script that can be used by others in the lab to process EEG data. Just as I learned through my projects at CHEPS, there are always ways to improve the functioning of healthcare systems and processes!”

Thanks to Lauren for the update! We love seeing our CHEPS alums continue to do exciting and innovative work.

CHEPS had the pleasure of a visit from recent alum Sheridan Tobin recently when she returned to Ann Arbor for a football game. Sheridan, who graduated with her B.S. in Public Health in May 2019 worked at CHEPS during her final year of studies. She’s now working as a support counselor at a community-based mental health non-profit that serves young people in foster care and the juvenile probation system. She said that, while her job now is definitely different than what she did with CHEPS, she took what she learned at Michigan with her. “In working in the hospital systems, a lot of it is figuring out the logistics of how working in direct-care works. I think having some experience observing at hospitals and just being in the thick of it in a clinical setting, it looks different in community-based, but I think having some of that background was helpful,” she explained. “Also, when I came into CHEPS, I didn’t know anything about what CHEPS was doing. I was non-engineer learning all of that. And, in my current job, I don’t have a mental health background like my colleagues do. I’m kind of learning again in a different way how to take my background into something new and with people coming from different places so it’s interdisciplinary in kind of a similar sense.” Thank you for visiting, Sheridan! We love seeing our alums!

marla November 11, 2019:

On November 11th, Dr. Lavanya Marla presented her work on “Data-Driven Greedy Policies and Performance Bounds for Ambulance Location and Deployment” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Marla is an Assistant Professor in Industrial and Enterprise Systems Engineering at the University of Illinois- Urbana Champaign. Dr. Marla previously worked as a Systems Scientist with Heinz College at Carnegie Mellon University. Her research currently focuses on using data-driven optimization, statistics, and machine learning to construct robust, decision-making models specifically related to transportation logistics.

Dr. Marla’s lecture outlined her work related to modeling and optimization of ambulance location and deployment. Her research started with observations of the ambulance system in India where only 750 ambulances are available per 75 million people. This highly resource-constrained system sparks questions about how access to a limited number of ambulances can be improved and optimized when adding additional ambulances to the system may not be possible. Dr. Marla and her colleagues worked model the current ambulance system using data from 10,000 emergency calls and by incorporating congestion and human behavior patterns. Use of the Greedy Algorithm allowed for simulation of system changes at various ambulance sites to see how the number of calls answered in 15 minutes or less, number of calls answered in 30 minutes or less, and the number of unserved calls could be affected or improved. By carefully determining model constraints, Dr. Marla and her colleagues were able to show that through static ambulance repositioning, they could improve the number of calls served in 15 minutes or less by 6.1% and by dynamic repositioning, improvements of 39% were possible. Through careful data analysis and proper constraint definition, complex real-world systems can be significantly improved and lives can ultimately be saved.

We thank Dr. Marla for braving the terrible snowstorm to participate our seminar series and present her fascinating, complex, and impactful work.

On Friday, November 8th, many CHEPS students presented at the Engineering Research Symposium (ERS). ERS is a university-wide event that showcases undergraduate and Ph.D. student research. CHEPS students had the opportunity to submit an abstract and poster for research projects that they are involved in at CHEPS! Here are the posters that were presented at the symposium:

This event gave students a chance to show off their work and network with other engineering students and faculty. Here are some quotes from CHEPS students about their experience during the symposium:

“I think ERS was a fun experience. I loved that it was in the Dude so we could run into classmates and friends. I also think it was good practice for the CHEPS Symposium. It made me think about how to quickly explain the important parts of the project to someone that has no idea what the project is about. Usually we talk to collaborators or peers about our work, so it was good to get practice talking to other people prior to the symposium.” – Kate Burns

“This symposium was a great experience for me to not only show off the great work we have been doing at CHEPS but to also learn about other impressive research being conducted throughout the university. Although my poster had minimal turnout, the people that did stop by seemed extremely interested and had interesting perspectives and ideas that our team had not previously considered.” – Matt Levenson

“I really enjoyed being able to talk to other presenters about my project as it gave me valuable experience in being able to verbalize all that we have done since the summer. I also enjoyed being able to see other projects. Everyone’s projects were all very interesting!” – Luke Liu

“I would say the ERS was a great opportunity to share our work with the other members of the Michigan Engineering community. I was happy to see so many people engaged and interested in the work we do on the TRAUMA team.” – Hannah Strat

krautmann November 4, 2019:

On November 4th, Michael Krautmann presented his work on “Improving Access to Medicines in Low- and Middle- Income Countries” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Michael is an alumnus of the U of M Industrial and Operations Engineering Department and worked as a Peace Corps volunteer in Zambia for three years after graduating. Michael joined the William Davidson Institute Healthcare Initiative at the University of Michigan in 2015 and his research and consulting currently centers around strategy and decision-making to improve public health efficiency, services, and supply chain.

Michael’s presentation highlighted his experience on the ground-level in Zambia where he worked to understand and identify supply chain inefficiencies in health care clinics. Lack of access to basic medications in many parts of the world is thought to be a direct result of bad roadways, lack of electricity, and other physical barriers when, in reality, many companies outside of healthcare have already successfully bridged those gaps to make their products available in the most remote areas of the world. Instead, Michael pointed to a lack of infrastructure and organization as the major barrier to proper healthcare access. In order to effectively convey the complexity of the supply chain system in countries like Zambia, Michael and his colleagues use detailed process maps, supply chain software tools, and relevant performance metrics such as clinic reporting rates and accuracy. Throughout his lecture, Michael stressed the importance of effectively presenting the problem when trying to motivate change and spark action, especially in the incredibly complex healthcare industry.

Michael’s slides and a video of his talk are available for viewing.

We thank Michael for taking the time to participate in our seminar series and sharing his valuable life experience and advice about navigating difficult healthcare problems and truly making an impact.

Join us on Monday, November 11th when Lavanya Marla, Ph.D. will discuss “Data-driven Greedy Policies and Information-Relaxation Bounds for Ambulance Location and Deployment.”

jason lunch and learn October 29, 2019:

CHEPS alumnus Jason Card came back to the University of Michigan to give a Lunch & Learn discussing his experience working with the Johns Hopkins Applied Physics Laboratory (APL). The APL was started during World War II to develop a better way for the US Navy to combat fighter planes. From that point, they have started to tackle different challenges, such as developing technology to allow a paraplegic to use prosthetics, a tool to manage epidemic outbreaks, and a tool to reduce healthcare-associated infections. When it comes to healthcare research they hope to revolutionize health through science and engineering.

Jason’s main focus of work is on value-based care and the musculoskeletal (MSK) applied value atlas. For value-based care, the project goal is to create a patient-centered healthcare process. The idea behind this is to get coordinate multiple specialists in one facility and get them to talk about complex patients together. By doing this, it reduces the number of appointments needed and allows the doctors to effectively communicate with one another. In regards to the MSK applied value atlas, they want to be able to create an atlas of historical data on injuries in the military. With this data, they will be able to accurately predict which occupations and areas are susceptible to specific injuries. In addition to an alumnus working on it, our own CHEPSter Jordan Goodman interned at the APL this summer and helped Jason with this project!

Jason also filled attendees in on the positions APL will be looking to hire interns and graduates in soon and took the time to talk one-on-one with several CHEPS students. Thank you, Jason, for traveling back to UofM to discuss ways to apply the knowledge we learn in CHEPs.

On October 28th, Katie Esper presented her work on “Applying Systems Engineering to Ensure Military Readiness and Health” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Katie Esper joined the Johns Hopkins University Applied Physics Laboratory in 2010 as a health systems engineer and is currently the Program Manager of Force Health and Readiness. Her work centers around a mission to ensure a medically ready force, ready medical force, and delivery of safe and effective healthcare across all military and humanitarian missions. Katie is also an alumna of the University of Michigan Industrial and Operations Engineering Department.

During her presentation, Katie highlighted the dual mission of the U.S. Military Health System which consists of the readiness and benefit missions. The readiness mission focuses on ensuring that there is a medically ready military force as well as a ready medical force to be deployed in wartime and on humanitarian missions around the world. The benefit mission refers to providing healthcare benefits to the 9.5 million military health beneficiaries in the U.S. Both of these missions present unique engineering challenges related to the determination of readiness measures, root cause analysis, and prevention of injuries sustained during training, and prediction of materials, staff, and other resources needed at military hospital sites. The medical force deployed on these missions must be adequately prepared for the scenarios that they are likely to encounter. In peacetime, it is critical to ensure that medical staff have opportunities to practice their skills in complex trauma cases through hospital experience or simulation. By employing systems engineering approaches, Katie and her colleagues tackle these challenging problems in order to ensure the safety, health, and welfare of our military personnel and those who support the front lines.

We thank Katie Esper for participating in our seminar series and highlighting the important and often overlooked challenges present in our military health system today.

CHEPS students, alumni, and faculty attended the 2019 INFORMS Annual Meeting in Seattle, Washington from October 20th-23rd. The INFORMS Annual Meeting brings together academic researchers and industry thought leaders working in the fields of operations research, management sciences, and data analytics. The CHEPS presentations included:

INFORMS was a great opportunity for current CHEPS students to visit with alumni who are continuing their great work of moving healthcare forward using engineering tools. Current students particularly enjoyed seeing Drs. Karmel Shehadah and Donald Richardson, two CHEPS alumni who each defended their dissertation earlier this year. Students also attended several sessions from colleagues doing great work at other institutions, including Northeastern University, North Carolina State University, and Mayo Clinic.

Students who attended said their favorite thing about attending this year was:

“I met Peter Jackson, the advisor of my Master’s degree’s very first case study project, at the AAS dinner. Peter had given us a lot of great advice and help for the project and also for the whole Master’s journey. Not long after the project, he retired and went to SUTD in Singapore, so it feels really amazing to be able to meet and greet him again.”-Junhong Guo, IOE Ph.D. Student

“Watching Dr. Jenna Wiens [Assistant Professor, Computer Science and Engineering] present for the first time at INFORMS on learning from clinical time series…she was eloquent and very inspiring to me. She was part of the session in which I presented, which was empowering because she is a powerhouse. Others in the session included Dr. Marina Epelman [Professor, Industrial and Operations Engineering] and Carolina Riascos [Ph.D. student, University of Toronto]. I felt honored to be part of such a strong session of women making a difference in healthcare” – Amanda Moreno Hernandez, IOE Masters student

“Getting to share a newer project on access to specialty care for rural patients. This is a newer project and it was my first time sharing it outside of CHEPS. There was great feedback and many new ideas that I’m excited to explore. I am thankful to Dr. Kayse Maass (Assistant Professor, Northeastern University) for inviting me to speak in the session. My second favorite part of visiting Seattle was the Cinnamon Works cookies!” – Adam VanDeusen, IOE Ph.D. student

October 18, 2019:

Friend-of-CHEPS Mark Van Sumeren took time out of his busy schedule (including welcoming a granddaughter to the family this week!) to speak with CHEPSTERs this past Friday. Drawing on his vast experience in the industry, Mr. Van Sumeren shared seven key tips on launching a successful career in healthcare. Mark described his career as “anything but a straight line” and shared his journey from UM to the Detroit Medical Center to Ernst & Young to Owens & Minor before starting his own consulting firm, Health Industry Advisor LLC.

In brief, Mr. Van Sumeren’s seven tips were:

1. Healthcare is a great career industry, due to the passionate workforce and need for talent with IOE skills.

2. You must reinvent yourself continually by growing your skillset to match the needs of the industry.

3. Lifelong learning is key! You must surround yourself with people from whom you can learn and who want to learn from you.

4. Culture matters! If the culture of the organization you find yourself in is toxic, run!

5. Passion is everything! “Go where it takes you, leave when it’s gone.” If you’re not passionate about the work you’re doing and don’t have that same “drive” it’s time to find a new problem to solve and place to do it.

6. Take on the problem that no one else will, by finding a tough problem and attacking it. If you choose the problems you want to solve, you won’t get stuck with the uninteresting ones.

7. Those who get ahead: Work well with others, deliver consistently, and make others successful. Above all else, Mr. Van Sumeren emphasized that those who have a “Hall of Fame” career find ways to make the people around them successful. He relayed the anecdote that at Ernst & Young, the measure of success for Partners was not how many projects they sold, but how many other partners they made.

Mr. Van Sumeren fielded several questions from students including sharing that to motivate training coworkers on a task, you have to get over the “It’s faster to do it myself” attitude. By focusing on the time you’ll save not having to do the task next time and the benefits of having a new set of eyes on the problem, you set yourself and your coworkers up for success. He also shared some of the nuances of working in different corporate structures including non-profit, partnerships, publicly traded, and private equity. Mr. Van Sumeren also reminded students that perceived risk in a career move should be viewed as exciting rather than daunting since it represents an opportunity for growth.

Thanks to Mr. Van Sumeren for sharing so many valuable insights and taking the time to carefully consider students’ needs as they enter their next phase of life. We look forward to having you visit CHEPS again in the future.

Mower Provost October 7, 2019:

On October 7th, Dr. Emily Mower Provost presented her work on “Human-Centered Computing: Using Speech to Understand Behavior” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Mower Provost is an Associate Professor in Computer Science and Engineering at the University of Michigan. Her research is focused on analysis and modeling of complex human behavior and expression of emotion for potential applications in improving diagnosis and treatment techniques for mood disorders. Using algorithm approaches, Dr. Mower Provost and her colleagues aim to characterize and predict human behavior, emotions, and moods.

Although speech analysis has applications in several fields, Dr. Mower Provost highlighted the use of speech assessment and algorithms for monitoring bipolar disorder. Human speech patterns are incredibly complex and are influenced by many external factors such as the environment in which people are speaking, the personality of the speaker, emotions, and lexical content of the conversation. Pharmaceutical treatments do currently exist for bipolar disorder, however, patient compliance can be problematic. Frequent check-ups and potential rehospitalization can be incredibly costly and often follow potentially catastrophic manic and depressive episodes. Within the Chai Lab, Dr. Mower Provost focuses on audio-visual emotion modeling and assistive technology development to track mood patterns of bipolar patients, monitor patient conditions, and predict possible manic or depressive episodes before they occur. Personal and clinical assessment calls of bipolar patients and healthy controls were monitored by the research team (with participant consent) over a 6-12 month period and speech patterns were annotated for rhythm and acoustics. After several years of work to control data variability, the team was able to successfully demonstrate a correlation between mood and emotion and valence (positivity) and activation (energy) which has immense potential to be applied in clinical mood disorders as well as other diseases.

A video of the presentation is available for viewing.

We thank Dr. Mower Provost for her presenting her outstanding work and we are excited to see where this data can be applied in the future.

There will be no seminars on Monday 10/14 and 10/21. Please join us again on Monday, October 28th when Katie Esper, MPH, MHCDS of Johns Hopkins APL presents “Applying Systems Engineering to Ensure Military Readiness and Health.”

bagian September 30, 2019:

On September 30th, Dr. James Bagian presented his work on “Embedding Patient Safety into the Fabric of an Organization: Critical Elements to Make it Happen” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Bagian is the Director of the Center for Healthcare Engineering and Patient Safety and a Professor of Anesthesiology in the Medical School and College of Engineering at the University of Michigan. He served as the first Director of the VA National Center for Patient Safety (NCPS) and the first Chief Patient Safety Officer for the Department of Veteran’s Affairs from 1999 to 2010 where he launched numerous patient safety programs and tools that have been adopted worldwide. Dr. Bagian also served as a NASA astronaut on two Space Shuttle missions and was an investigator of both the Challenger and Columbia space shuttle disasters. His work currently centers around implementation of systems engineering approaches to the investigation and analysis of adverse medical events to offer solutions, prevent repeat occurrences, and enhance patient safety.

Throughout his lecture, Dr. Bagian drew parallels between adverse events and statistics in the aviation and healthcare industries. The differences in the reporting of adverse events and employment of corrective actions between the two industries was striking. A 2010 study carried out by the Center for Medicare and Medicaid Services (CMS) found that approximately 1.5% of patients treated in hospitals die per year as a result of adverse medical events. Another 27% of patients were victims of adverse events resulting in temporary or permanent injury. Dr. Bagian highlighted the impact that culture within the healthcare industry has on the occurrence of these events. The “compliance culture” in which care providers uncritically and robotically follow rules and regulations rather than actively considering the appropriateness of the policy or procedure for the individual being treated and when necessary questioning before acting can be very dangerous. Shifting to a “safety culture” is essential to avoid shaming of individuals who make mistakes and to encourage proper reporting of close-call or near-miss events that can be studied to employ effective solutions that prevent harm in the future. In healthcare, there is an expectation that people will never make any mistakes which is simply impossible. Through his work with the VA and at Michigan Medicine, Dr. Bagian has shown how systems engineering approaches related to patient safety can change the culture within the hospital and attitudes that focus on identifying the underlying root causes and contributing factors so that meaningful and sustainable countermeasures and improvements can be implemented. Offering new tools and programs to support accident reporting, including close calls, and swift systems-based corrective actions can ultimately ensure patient safety and save lives.

We thank Dr. Bagian for his engaging presentation and for bringing his unique perspective and background to the extremely important topic of patient safety.

taaffe September 23, 2019:

On September 23rd, Dr. Kevin Taaffe presented his work on “The Impact of Communication, Coordination, and OR Design on Surgical Patient Flow and Safety” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Taaffe is the Harriet and Jerry Dempsey Professor of Industrial Engineering at Clemson University and worked in the transportation logistics industry for American Airlines and Sabre earlier in his career. His research centers around the use of simulation models to optimize patient and provider workflows in the clinical environment. During his lecture, Dr. Taaffe focused on the use of simulations to pilot a mobile application designed to map patient flows through the perioperative stages of surgery and to optimize operating room design.

The perioperative stage of surgery includes pre-operation, during operation, and post-operation care. As you can imagine, there are several tasks involved in moving patients through this process and communication and coordination between various job functions are essential. The complexity of this process can make communication between lab technicians, nurses, physicians, surgeons quite challenging. As a result, Dr. Taaffe and his team sought to streamline the process of updating and accessing patient statuses through the Periop Mobile Learning System (PeriopMLS). PeriopMLS is a mobile application for Android phones which organized patient status updates through a convenient checklist and color-coded system. Nurses and clinicians could use this application to see completed and upcoming tasks for each of their patients. Dr. Taaffe and his team made use of ARENA simulation modeling to pilot this application without disrupting the clinical environment through a live test. The use of simulation modeling to test the application provided the team with valuable feedback and the opportunity to train users. User feedback and application prototypes were passed onto Epic to potentially integrate and improve features of the current electronic medical record system.

Dr. Taaffe’s second project involved collaboration between his engineering team and architects to determine key design considerations affecting work-flow in the operating rooms. Clutter caused by equipment and people in the OR can pose safety risks to patients and providers. After studying video recordings of 35 procedures and noting contact events (when individuals were with 0.6m of each other) and traffic patterns, Dr. Taaffe and his team developed a simulation model to determine how several factors including room size, number of doors, number of staff members, table orientation, location of nursing workstations, and procedure type influence the total number of contact events between staff members. One interesting finding was the statistically significant impact of table orientation on contact events. The impact of design factors can be further assessed to determine optimal room design and potential impact of design choices.

Dr. Taaffe’s slides and a video of his talk are available for viewing.

We thank Dr. Taaffe for participating in our seminar series and demonstrating the importance of stakeholder and user feedback to improve our healthcare system and workflows.

Join us for our next seminar on September 30th at 4:30 pm in 1123 LBME when CHEPS Director Jim Bagian, MD, PE discusses “Embedding Patient Safety into the Fabric of an Organization: Critical Elements to Make it Happen.”

huang September 16, 2019:

On September 16th, Dr. Shuai Huang presented his work on “Smartphones Medicalized, with Data Analytics for Complex Disease Management” as part of our Providing Better Healthcare Through Systems Engineering Seminar Series. Dr. Huang is an Associate Professor in the Department of Industrial and Operations Engineering and an adjunct faculty member in the Department of Biomedical Informatics and Medical Education (BIME) and the Integrated Brain Imaging Center (IBIC) at the University of Washington. His research focuses on the development of new methods for modeling, diagnosing, and monitoring complex network diseases such as Alzheimer’s disease, Type I diabetes, and clinical depression. He also works to develop statistical and data mining tools for a variety of large datasets including genomic, neuroimaging, and demographic data to facilitate new scientific discoveries.

In his presentation, Dr. Huang highlighted the potential of using smartphone data to track disease trajectories and monitor patient conditions. Currently, 81% of adults in the U.S. own smartphones which can track, collect, and store enormous amounts of data ranging from GPS to audio/video recording to proximity sensing. By harnessing the data tracked by our phones, we can gather valuable behavioral data which can be used to track diseases such as Alzheimer’s and depression. Dr. Huang gave examples of video and audio data that can be used to diagnose and monitor patients through their speaking patterns and facial expressions recorded on smartphones. Biomarkers such as changes in the distance between facial features and the ratio of laughter to words when we talk can be indicative of depression. Development of new methods for sorting the data recorded by smartphone technology offers exciting new ways of informing physicians with real-time patient data recorded outside the clinic. Painting a more complete picture of the patient’s responses to treatment can allow for the design of more precise treatment plans and connect patients with accurate and valuable health information.

Dr. Huang’s slides and a video of his talk are available for viewing.

We thank Dr. Huang for his willingness to participate in our seminar series and present his fascinating work.

Join us for our next seminar on September 23rd at 4:30 pm in 1123 LBME when Kevin Taaffe, Ph.D. discusses “The Impact of Communication, Coordination and OR Design on Surgical Patient Flow and Safety.”

tam September 9, 2019:

George Tam, a CHEPS alum who earned his B.E. in Industrial and Operations Engineering in 2014 and M.Eng. in the same field in 2015, returned to campus this week as to recruit for Delta Airlines where he’s employed as Senior Analyst in Transatlantic Revenue Management. While in Michigan, he also stopped by his old stomping ground at CHEPS. In addition to giving a Lunch & Learn for an audience of about half CHEPSters and half IOE undergraduates, he spent the day at CHEPS, having informal conversations with students. “Whenever I meet with students, it’s a two-way street,” said George. “I tell them about Delta or give career advice, but I learn from them as well.” And, we got the benefit of not one but two CHEPS and IOE alums! Sanjeev Muralidharan who also works as a Network Planner at Delta, spent much of the day at CHEPS as well and chimed in with many helpful insights during George’s Lunch and Learn and the Q&A session after.

Dean Golan, an IOE undergraduate, said, “Having the chance to speak with George one-on-one about his experiences at Delta provided me with an in-depth understanding of network planning and revenue management career opportunities. I am also now incredibly interested in pursuing a career in the airline industry, so I am very grateful for this opportunity!”

In his Lunch and Learn presentation, George discussed how all of the aspects of IOE that are involved in his work at Delta Airlines. “In scheduling, I’ve used so many IOE 310 and 510 skills,” he mentioned. He also pointed out that aviation and the work students are doing at CHEPS isn’t as different as some might imagine. “The beauty with healthcare and aviation is there are transferable skills and concepts,” he said.

Another tie between CHEPS and the airline industry George observed was the importance of cross-collaboration. As an example, he cited an app Delta developed to allow all employees involved with a flight, from catering to the flight crew to gate agents, to talk with one another. He compared to his time at CHEPS where, as an engineer, he was able to collaborate with healthcare practitioners and gain valuable insights on how to solve problems in the healthcare industry.

Another area where George had some excellent insights to share was preparing for career fairs and corporate information sessions. He’s been recruiting for Delta for several years and emphasized the importance of the 4 Ps to students, “print (resume and what you’ve achieved), pitch (what makes you unique), personality (Would someone want to work with you?), passion (Would you like working here?).” He also helped students with some factors to consider when deciding whether to pursue grad school or a full-time job after their undergraduate studies. In all decisions, he urged the students to “Think about your aspirations. Where do you want to be later in life, not just next year?”

George wrapped up his presentation by encouraging attendees to consider several factors when deciding on their first full-time job: work/life balance, opportunities for mentorship, building bridges, maintaining bridges, and productively addressing setbacks.

This week, Dr. Amy Kilbourne presented her work on “Driving Innovation, Implementation, and Sustainability in a Learning Health System” as part of our Providing Better Healthcare through Systems Engineering Seminar Series. Dr. Kilbourne is the Director of the VA Quality Enhancement Research Initiative (QUERI) and a Professor of Psychiatry at the University of Michigan Medical School. QUERI aims to improve the health of veterans in 40 cities nationwide by accelerating the implementation of researched treatments and therapies in real-world practice.

Currently, the lead time for implementing new, researched treatments on the frontline is approximately 17 years. As you can imagine, this timeline stalls innovation and prevents the improvement of patient outcomes which can be incredibly frustrating for researchers, clinicians, and patients alike. In her presentation, Dr. Kilbourne attributed treatment implementation failures to the lack of organized implementation strategies, education, and methods of training for frontline clinicians. So-called “late adopter” healthcare sites frequently delay implementation of new treatments due to low bandwidth, newly established competing innovations, or competing priorities.

To address the hesitations of late-adopting sites, QUERI works to combat their concerns by providing education through internal and external facilitators and replicating effective programs (REP). Additional facilitators and support are offered to sites that prove more difficult to engage through enhanced REP programs. In addition, Dr. Kilbourne discussed the innovative use of Sequential Multiple Assignment Randomized Trials (SMART) to inform the development of adaptive intervention strategies and better accommodate the changing needs of sites and individuals. Through the organized implementation plans offered by these initiatives, improved patient outcomes have been recorded and other potential applications including mental health treatment access in schools are being explored.

Dr. Kilbourne’s slides and a video of her talk are available for viewing.

We are so grateful for Dr. Kilbourne’s engaging lecture and her incredible work to improve mental health outcomes of our beloved veterans.

CHEPS Associate Director Amy Cohn had the privilege of speaking to students in the University of Michigan Medical Scientist Training Program (MSTP) at their annual weekend retreat at the Ralph A. MacMullan Conference Center on Higgins Lake this August. The MSTP Program “prepares physician-scientists for careers in academic medicine” by enabling them to pursue their M.D. and Ph.D. simultaneously. While many of the students are pursuing Ph.D. in a field that is traditionally paired with medicine such as biology, there are a growing number of students from less common fields including some from the Industrial and Operations Engineering Department. In fact, CHEPS collaborator and IOE Ph.D. student Erkin Otles introduced Professor Cohn before her talk and hosted her during the event.

“I enjoyed getting to spend some time informally with the students and appreciated doing so near the beauty of Higgins Lake,” said Professor Cohn. “I was particularly impressed by the poster sessions and really enjoyed talking to the undergraduates who were participating in the retreat. I hope to see some of them at CHEPS in the future.”

Her presentation was titled “An Engineer’s Perspective on How to Improve Healthcare Delivery.” While she was prepared with fifty slides, Professor Cohn was only able to get through about ten of them due to having so many questions during her presentation and engaging in a lively discussion with the attendees. “It was exciting to see how many students, even in more traditional fields, were interested in ways that engineering could contribute to healthcare,” she said. “I’m grateful for the opportunity to present at the retreat and to connect with these students. I hope the relationship between CHEPS and MSTP will continue to grow.”

Dr. Anurag Malani is an alumnus of the University of Michigan’s IOE Department and is currently the Medical Director for the Infection Prevention and Antimicrobial Stewardship Programs at St. Joseph Mercy Health System.

Dr. Malani spoke to the CHEPS students about his path from engineering to medicine and cited his IOE studies as being immensely valuable in his career as a medical doctor. According to Dr. Malani, the IOE curriculum provides skills that are important to practicing physicians including the ability to understand data, take a systematic view of processes, and problem solve. Students also learned Dr. Malani’s advice on how engineers can best communicate with physicians.

We also had the pleasure of hearing from a second Dr. Malani! Dr. Preeti Malani, the Chief Health Officer and a Professor of Medicine in the Division of Infectious Diseases at the University of Michigan and Dr. Anurag Malani’s sister, attended the Lunch and Learn and shared her insights with students as well. She also spoke about her experience working with Maize & Blue Cupboard whose mission is “to ensure members of the University of Michigan community, whether on a tight budget or physically restrained from getting to a grocery store, receive equitable access to healthy, nutritious, and nourishing food and the ability to prepare it for themselves or others.” We appreciated learning about this valuable resource on campus!

On Aug 1st and 2nd, CHEPS students woke up bright and early to volunteer at Discover Engineering. CHEPSters collaborated with high school students on an emergency room simulation game and several Ergolympics activities, which were games designed to demonstrate ergonomic principles. By the end of the 20-hour ER staffing simulation, Team Fish pulled ahead with a net hospital profit of $10,925. The high school students loved the Ergolympics stations, especially cornhole and Stroop. For cornhole, students lifted weights between rounds to understand the effects of fatigue on posture and performance. Meanwhile, during Stroop, students tried to match a list of colored words to colored squares on a board as quickly as possible. In the debrief session, students were taught the aims of the games and also gained a foundational understanding of what industrial engineering is all about. By the end of Discover Engineering, all the high school students learned one very important lesson: “Engineers make things. Industrial engineers make things better.”

CHEPS collaborator Emily Boltey successfully defended her Nursing PhD dissertation, titled “Measuring the process of interprofessional collaboration in the care of critically ill adults,” on Friday, August 2nd. In her research, Emily conducted a time-motion study on interprofessional collaboration in the ICU. Many errors in the ICU originate from systematic problems, not individuals. Emily realized that one way to address this was to improve teamwork and the first step to doing so was to be able to measure collaborative actions between coworkers. Emily collaborated with CHEPS to create an app that allowed her to record collaborative actions quickly and efficiently while performing observations. CHEPS Associate Director Amy Cohn was a member of Emily’s committee along with Chair Professor Deena K. Costa, Dr. Jack Iwashyna, and Dr. Julia Seng.

Moreno-Hernandez, our recent Ph.D. alums Karmel Shehadeh and Donald Richardson, and Professor Amy Cohn participated as speakers of multiple technical sections. The conference kicked-off with a full house technical session titled Improving Patient Access and Flow in Outpatients Clinical Settings. Karmel, Jakob, Michelle, and Donald presented their work and projects in this session. Their presentations were:

“I was thrilled to present our work on simulating an outpatient endoscopy clinic to an audience with such a wealth of healthcare experience. Watching my fellow CHEPSters and IOE students present their work and gracefully answer tough questions from the audience was so fun and a great reminder of how awesome CHEPSters are,” said Jakob.

Our very own Amy Cohn also gave a talk titled “Implementing Provider Scheduling Decision Support Tools in Clinical Practice.” Many of our friends from the Industrial & Operation Engineering Department also attended the conference and presented their work. Daniel Otero and Luke DeRoos, both first-year IOE Ph.D. students, presented talks titled “Cholesterol Follow-Up Policy in the context of Preventive Treatment of Cardiovascular Disease” and “Modeling the Effect of Presumed Consent on Organ Transplant Waiting List Candidates” respectively. Other sessions were built around topics such as application of optimization in disease dynamic and treatment policy, prediction and prevention of diseases with the use of different models, resource allocation, policymaking, and many more. During the last day of the conference CHEPSter Amanda presented work done on “Simulating the Flow of Patients with Aortic Dissection through a Cardiac Intensive Care Unit.”

Without a doubt, the conference was a great experience and opportunity to connect with other professionals who are “Transforming Health with Data, Mind, and Hand.” As Michelle said, “It was great to broaden my view of IE in healthcare and meet brilliant people.” We all also enjoyed learning about the landmarks of Boston and Cambridge from our Associate Director. In addition, our baseball fans Jakob and Amanda got to see the Red Sox playing the Yankees at Fenway Park.

DeRoos Lunch and Learn July 12, 2019:

On Friday, July 12th, CHEPS students welcomed IOE PhD candidate Luke DeRoos for a Lunch and Learn. Luke shared his research related to the possible influence of presumed consent in organ transplantation.

Luke began with data illustrating a long-existing challenge in organ transplantation which is the extremely high organ demands across the United States. “Over a hundred thousand people are waiting for organs” and “22% have died while waiting for organs,” he explained. Presumed consent policy, if implemented, could be a very effective way to mitigate the high demands. How will presumed consent affect the organ waitlists? That’s where Luke’s research started.

Luke intended to understand the number of waiting patients, waitlist removal, and years of life gained after transplantation under the influence of higher organ supply due to presumed consent. He built up the predicted model and generated data under ideal allocation and random allocation of organs. The result will fall between that range when in practice. The results showed that the higher impact the policy is expected to produce, the fewer people who will die or become too ill on the waitlist before getting a transplant, and the more years of life the patients will gain after transplantation. As a result, Luke drew the conclusion that presumed consent would bring large gains in years of life. But the organ shortage situation will still exist.

Luke also shared other research he is working on, including finding appropriate metrics to measure the performance of OPOs across the country. CHEPS students and others in attendance were very interested in Luke’s research. They asked questions like “Will wealthy people get advantages on the organ waitlist?” and “How long can it be between the organ beingremoved and implanted?”

At the end of the Lunch and Learn, Amanda represented CHEPS thanking Luke for his presentation and giving him a small gift from CHEPS.

Sheridan Tobin presenting M-Safety’s work at the 2018 CHEPS symposium
July 12, 2019:

The M-Safety team marked a big milestone in June as the patient safety displays they’d been working on went live on one hospital unit at Michigan Medicine! The display, which was developed through a collaboration between the University Hospital 8DNS unit at Michigan Medicine, a multidisciplinary team of researchers from Internal Medicine, Nursing, and Engineering, and CHEPS, shows real-time data on the presence and duration of medical devices and skin issues. Clinicians in the 8DNS unit are excited to be utilizing the displays. The goal of the displays is to improve provider awareness of medical device placement and skin issues, which should enable prompt delivery of risk-reducing interventions, such as medical device removal and targeted skin care or repositioning. You can learn more about the M-Safety project on the project page.

karmel defense
July 10, 2019:

CHEPS PhD student Karmel Shehadeh successfully completed her PhD defense on Wednesday, July 10th. Karmel’s dissertation was titled “Stochastic Optimization Approaches for Outpatient Appointment Scheduling under Uncertainty.” The dissertation studies three challenging stochastic outpatient scheduling problems with broader applications within and outside of healthcare and proposes new and tractable stochastic optimization models and approaches for solving them. First, the dissertation proposes a new stochastic mixed-integer programming model that overcomes the computational challenges of outpatient procedures scheduling with random durations contrast to the existing models in the literature. Second, the dissertation studies a stochastic adaptive outpatient scheduling problem which incorporates the patients’ random arrival and service times. Finally, the dissertation proposes a tractable distributionally robust (DR) optimization approach to outpatient colonoscopy scheduling with bimodal and ambiguous colonoscopy duration.

Karmel’s PhD is in Industrial and Operations Engineering. CHEPS Associate Director and IOE Professor Amy Cohn and IOE Assistant Professor Ruiwei Jiang were her advisors. CHEPS and IOE students, faculty, and staff as well as many of Karmel’s friends attended the defense and celebrated her hard work and achievement with her afterward. While her family was not able to attend in person, they were able to watch the recorded version of her talk and share in the excitement of the day.

Karmel wrapped up her defense by thanking all who had supported her throughout her PhD work and in preparing for her defense. She said she feels honored and lucky to have worked with and known Prof. Cohn and Prof. Jiang, and thankful for all of their support and for teaching her tons of things that she cannot possibly thank them enough for. Most importantly, how a successful & impactful scholar and mentor should be. She is also thankful for her committee member Prof. Marina A Epelman for supporting her and contributing to the dissertation in many ways and for the insights of her cogent Prof. Anne Sales

Congratulations, Dr. Shehadeh!

CHEPS decided to expand its volleyball horizons by arranging a tournament with MLD3, another engineering research group MLD3. We actually played with two groups on campus the first being MLD3 (Machine Learning for Data-Driven Decisions), who develops machine learning methods within healthcare. The second was a group of rising Freshman in an organization called M-STEM. The group happened to be walking by as the tournament started and ending up joining in! It was a hot day outside, comfortable in the shade but scorching in the sun. The sand was almost unbearably hot on our feet. Shoes or socks were a must or you were jumping on or digging into the sand. We played every possible combination of games, with each group having two teams. Each team played every other team. Teams sitting out played rounds of 4 square, refined their volleyball skills on the sidelines, or sat in the grass and on the swings enjoying the summer jams. Ultimately, the two CHEPS teams faced off and both ended with 2 wins and 1 loss. So who were the ultimate champs? Guess we’ll have to find out next time.

On Sunday, July 7th, five CHEPSters decided to embark on a river tubing adventure down the Huron River. At a balmy 86 degrees, they began the journey at Argo park with a water-resistant* box of Costco pretzels and plenty of water to stay hydrated. But, after a perilous encounter with the white water cascades, the seemingly water-tight container was compromised and the fish began to dine on the CHEPSters’ last source of sustenance. Nonetheless, after a grueling hour of fighting off tree branches and sharp rocks, the crew survived the expedition to see another day.

bear lunch and learn July 3, 2019:

On Wednesday, July 3rd, CHEPS students gathered together for the long-awaited Lunch and Learn on bears, presented by Theodore Endresen. Through this brief introduction to bears, Theodore not only met but exceeded the expectations of his co-workers.

Theodore began his presentation by describing classifications: There are 8 main types of bears and 2 proposed phylogenies. He then sketched out how appreciation of bears has manifested itself across different countries. China, for example, has a breeding facility for pandas, which is greatly responsible for the slowly increasing panda population.

Starting with his favorite bear, the panda, Theodore went into in-depth explanations of each bear type, mentioning each type’s most important attributes. Panda bears, for example, have the largest molars of any bear, whereas polar bears have the highest bite force of any bear. Interestingly enough, the sloth bear, a seemingly harmless bear based on its name, is the most dangerous bear and tends to initiate attacks immediately.

After each bear type description, Theodore provided CHEPS students with “survival tips”, often accompanied by comical strips emphasizing the danger that bears present. These survival tips brought out Theodore’s humor, which all CHEPS students know and love.

Towards the end of the presentation, Theodore described different stances on bear conservation. Most importantly, he reminded us that, despite the friendly depiction of bears in the media and animation, bears are, in fact, very dangerous.

warner lunch and learn June 21, 2019:

CHEPS students gathered together on Friday, June 21st to hear our very own Julia Warner conduct a Lunch and Learn on effective meetings.

Julia started off the presentation by explaining how to schedule a meeting. She explained that it is important to always have a point person in charge, identify people whose schedules will be the bottleneck when planning a meeting, and to appropriately word emails to communicate effectively about meeting logistics.

She then described characteristics of a good meeting attendee, the top qualities being: provide the times you can arrive, review the agenda prior to the meeting, plan your outfit based on your meetings, and plan ahead to be on time.

Julia also talked about how to structure your agendas. Announcements should be first, and the least important items should be tabled last. It is important to include the assignments of the timekeeper, the scribe, and the facilitator. Additionally, “parking lot items”, items to be put on a later agenda, should be recorded and followed up on.

We ended the Lunch and Learn with an interactive whiteboard activity, brainstorming the Do’s and Don’ts of conference calls and the Do’s and Don’ts of dressing to meet with collaborators.

Julia reminded us at the end, to always end meetings on a positive note, by thanking everyone for their time and highlighting progress and accomplishments!

June 19, 2019:

CHEPS PhD student Donald Richardson successfully completed his PhD defense on Wednesday, June 19th, making him Dr. Richardson officially. Donald’s dissertation was titled “Operations Research Frameworks for Improving Make-ahead Drug Policies at Outpatient Chemotherapy Centers.” Delays are possible at each step of an outpatient chemotherapy infusion visit. These delays can negatively impact individual patients and have a ripple effect which can negatively impact staff and other infusion patients. Donald’s research, conducted with CHEPS and the UM Rogel Cancer Center, looks at ways to reduce those delays by helping hospitals determine which drugs can be made ahead and when in a way that saves time and creates little to no drug waste.

Donald’s PhD is in Industrial and Operations Engineering. CHEPS Associate Director and IOE Professor Amy Cohn was his thesis advisor. Current students, faculty, staff, and alumni from both IOE and CHEPS attended the defense along with Donald’s family and friends. Matt Rouhana, who worked on the chemotherapy project when it first started, even returned for the occasion! Donald concluded his presentation by thanking everyone who had supported him throughout his PhD including Prof. Cohn, his thesis committee, his collaborators at the UM Rogel Cancer Center, The Bonder Foundation, The SROP program, the Meyerhoff Scholars program, his family, and Peter and Josi who baked goodies for his defense!

bagian lunch and learn June 18, 2019:

On Tuesday, June 18th CHEPS Director Jim Bagian led a Lunch and Learn on the Columbia and Challenger shuttle investigations which he took part in during his time at NASA. Jim first discussed why the Challenger failed before diving into the investigation process and how it led NASA to conclude that the unusually cold weather on the day of the launch was ultimately to blame for the unfortunate accident. He also talked about how NASA added new safety features for future missions with all the problem solving and testing that went into it.

Jim next discussed the Columbia shuttle accident. He emphasized the importance of looking at all data available before coming to conclusions. By doing this, his team was able to recover 38% of the Columbia shuttle, which helped in their investigation as to what happened. Within the shuttle’s wreckage, some items had virtually not suffered any damage, examples such as an ink jet printer and Tonopen (a medical instrument used to measure intraocular pressure) were virtually untouched and still worked normally after the accident. This led to an interesting discussion about why some items survived how understanding the reasons for their lack of damage played a part in making the design of future space vehicles safer in the future.

Overall, Jim’s talk emphasized how the investigation process and data collection played a vital role in analyzing both the Challenger and Columbia accidents. These processes made for an interesting Lunch and Learn!

bagian lunch and learn June 14, 2019:

On Friday, June 14th, CHEPS Director Jim Bagian spoke to CHEPS students on Risk, Professionalism, and Ethics in Medicine and Engineering. Dr. Bagian spoke to the necessity of clearly defining the goal of any undertaking and balancing the acceptable risk of failure in executing the intended plan to achieve the goal against the value to be realized if successful and the opportunity cost associated with the endeavor. Recounting real-world examples, Dr. Bagian spoke to the necessity of clearly communicating the hazards and risks associated with any undertaking to all concerned parties as an essential attribute of professionalism in making decisions grounded in logic, not emotion.

The importance of distinguishing hazards from risks was emphasized so that groups would be better equipped to make effective decisions. Commercial aviation was used as an example to illustrate that while one of the hazards of flying is death resulting from a crash, the risk of being killed in a crash while traveling on a commercial airliner is less than one in 14 million. This illustrated that in considering hazards, the truly important point is really the risk that a hazard will cause an undesired outcome rather than the existence of the hazard itself.

Dr. Bagian also spoke to the necessity of maintaining a good sense of teamwork among coworkers and colleagues. One of the critical elements of a well functioning team is the deliberate efforts to breakdown hierarchical barriers to communication. Dr. Bagian gave an example from his time as the Chief Patient Safety Officer and the director of the National Center for Patient Safety at the VA where he would intentionally travel to meet with others in the VA who were his subordinates at locations that were of the greatest convenience to them to demonstrate by action that he respected them and valued their cooperation rather than have them meet at locations that were more convenient to him. In this way, he felt that he was able to develop more meaningful and productive working relationships. He also spoke to being willing to openly acknowledge when help was needed in order to obtain the best performance from team members.

Being able to draw on Dr. Bagian’s vast knowledge and experience is an amazing opportunity for CHEPSters and his accomplishments are a great reminder of what can be achieved through hard work.

shehadeh June 14, 2019:

CHEPS and Industrial and Operations Engineering PhD candidate Karmel Shehadeh, along with co-authors Prof. Amy Cohn and Prof. Marina A. Epelman, has had a paper accepted for publication in the European Journal of Operational Research (EJOR). The paper, titled “Analysis of Models for the Stochastic Outpatient Procedure Scheduling Problem (SOPSP),” is motivated by the work Karmel and her team at CHEPS have done with the University of Michigan Medical Procedure Unit. The outpatient clinic performs a variety of procedures, including a large number of colonoscopies. The team is working to build higher-quality schedules that incorporate the variability in procedure durations and other patient characteristics; with this work, it is possible to improve patient and provider satisfaction, reduce costs, and even achieve better clinical outcomes. A valuable tool in creating such schedules is the ability to solve the simpler (and yet still challenging) SOPSP as an embedded sub-problem. Shehadeh, Cohn, and Epelman propose a new stochastic mixed-integer linear program (SMILP) that overcomes the challenges of solving this well-known complex stochastic, combinatorial, and multi-criteria optimization problem.

“Publishing this work in a top OR journal such as EJOR inspires me to continue working on developing tractable and implementable Engineering and Operations Research frameworks for solving challenging real-world optimization problems,” said Karmel. “However, the more important reason for feeling thrilled about publishing this work is knowing that it will provide a valuable long-run solution for issues that we all face during a medical appointment. I very much enjoyed this intellectually rewarding research adventure with Prof. Cohn and Prof. Epelman, and am thankful for their support.”

Moeckel Lunch and Learn June 5, 2019:

CHEPS students, faculty, and staff met for a Lunch & Learn on Wednesday to hear about Rachel Moeckel’s career as a Health Systems Specialist in the VA Ann Arbor Healthcare System. Rachel is a CHEPS alum and graduated with a Masters in IOE with a HEPS concentration in 2017. After graduation, she discovered her current VA position through another CHEPS graduate! Now, she works on interdisciplinary teams to improve patients’ access to care throughout the VA. These projects lead change in a variety of departments, but Rachel has been working most frequently in surgery. Specifically, she tracks changes in access metrics, then collaborates with doctors, nurses, medical support assistants, administrative officers, and more to fix any issues that have arisen and that she has identified.

Rachel noted that CHEPS prepared her well for her position as a Health Systems Specialist, but she encourages recent graduates to also ask a lot of questions, engage in a variety of trainings, and immerse themselves in their new positions. That is how she grew to feel comfortable and competent at the VA and jumpstart her career! Rachel also recommended that CHEPsters find supportive managers to work for; from her experience, the people she works with makes the job productive, rewarding, and enjoyable.

In sum, the Lunch & Learn attendees enjoyed an informative session that provided advice for transitioning into post-graduation positions, as well as how to be successful in those roles. Thank you, Rachel, for returning to CHEPS to share your wisdom!

On June 4, 2019, the Institute for Healthcare Policy & Innovation (IHPI) had a Lunch and Learn seminar for students. The event was co-hosted by CHEPS Associate Director Professor Amy Cohn, Professor Ivo Dinov from the School of Nursing, & Dr. Sunghee Lee from the Survey Methodology Program.

During the first half of the seminar, each host gave their career story and explained the path that they took to get where they are today. As the hosts spoke, an unexpected theme of changing career paths became clear. Each of the speakers talked about the ways in which their paths had changed over the years and how they were happy with their direction, but it was different than they expected. For example, Professor Dinov talked about choosing mathematics over statistics for his undergraduate degree, even though he came from an accounting secondary school.

During the second half of the seminar, students were able to ask each speaker questions. Students seemed interested in the work of the speakers and the ways that they found to balance work and life in higher education.

In an environment such as healthcare, where the stakes are constantly high, it can be easy to resort to superficial knee-jerk resolutions that focus only on proximate causes of patient adverse events and close calls. In most organizations, close calls are even ignored and interpreted as events caused by good or bad luck and are not used in a proactive manner to identify and mitigate the threats to safe patient care that they represent. As systems grow increasingly complex, it is imperative that we choose to analyze the underlying contributing causes of a problem or vulnerabilities and mitigate them through actions that address the underlying systems-based contributing factors. It is important to go well beyond superficial actions that are limited to placing blame on individuals and focus exclusively on individually focused interventions such as training or changes in policy alone.

On Tuesday, June 4th, CHEPSters attended a Root Cause Analysis and Action (RCA2 = RCA Squared) training given by Director Jim Bagian and Program Manager Joe DeRosier. They developed this program which has been implemented in hospitals across the nation. Its premise may seem simple; break down an event until root causes and contributing factors are exposed, and identify system-based actions to address system vulnerabilities. The RCA2 process includes cognitive aids and tools to help teams consistently complete thorough and credible reviews.

RCA2 utilizes multidisciplinary teams with a combination of unique perspectives that meet to analyze adverse events with the objective being to minimize or eliminate the risk of future harm to patients. Traditional healthcare related investigations typically stopped at identifying causes such as human error or failure of an individual to follow a policy or procedure. RCA2 goes deeper to understand what contributed to the human error or why a policy or procedure wasn’t followed. Jim and Joe also detailed the importance of formulation and implementation of actions following these assessments (and how it wouldn’t be RCA2 without this). They highlighted the necessity of structural design changes that employ stronger actions that rely on characteristics such as forcing functions rather than those actions that only require individuals to rely on their memory such as only policy and procedure changes or training.

Above all, it is important to carry forward the mentality that RCA2 is built upon — a systems-based analysis to elucidate the root causes and contributing factors and the implementation of actions that mitigate these vulnerabilities. This is especially true in an environment such as healthcare, where patient safety is a constant top priority. Problems are multidisciplinary, multifaceted, and should always result in actions that concentrate on systems-based interventions that focus on prevention or mitigation of harm over the all too superficial and common responses that simply blame the individuals associated with the event in question.

This week we had the pleasure to hear from two recent CHEPS graduates, Justin Rogers and Theodore Endresen, about the Dermatology and Block scheduling projects respectively. The Dermatology project deals with creating a computerized tool to schedule dermatology residents each month in the dermatology clinic at the university hospital. The Block project, on the other hand, deals with scheduling residents in the internal medicine and pediatrics clinics in the university hospital. Head residents used to create these schedules manually which would take many days or even weeks of their time. With the help of these scheduling projects, we have been able to help them free up their time.

joe east April 22, 2019:

CHEPS Alum Joe East, Director of Patient Access and Flow at Maine Medical Center, was kind enough to stop by CHEPS on his recent visit to Ann Arbor for a “Snack and Learn.” Joe spoke broadly about his experiences at Maine Medicine and how CHEPS had prepared him for his work there, as well as addressing more specific questions from CHEPSters.

Joe spoke to some of the key pain points he’s identified with incoming patient transfers at Maine Med, challenges which relate closely to those CHEPS students are working on in the AD ICU project which looks to ensure appropriate capacity in the cardiac ICU for aortic dissection patients. Joe sees two key components to patient transfers: accepting the patient and assigning them to a bed, noting that it’s not uncommon for a physician to accept a patient without realizing there’s no bed available for them. Improving the communication between hospital staff, especially across units, has proven key in solving these challenges at Maine Med.

In addressing a question about how to communicate with physicians, who generally have a less analytical background than engineers, Joe spoke to using data as a jumping off point. Joe spoke to using data to get physicians and engineers on the same page and using data as a common communication tool. Tying data to positive financial impacts and/or patient outcomes is also very important. Along similar lines, Joe advised that young professionals should get to know the language of the healthcare providers they work with. “Don’t make them dumb it down for you,” he said, meaning know the abbreviations and shorthand they use so they don’t feel like working with you is an arduous task.

Hearing from such a motivated and capable professional like Joe was a great reminder of the kind of work CHEPS is preparing us for and was inspiring to make sure we take advantage of all the great opportunities we have here. Thanks to Joe for the great visit and we hope to see you again soon.

Several CHEPS students participated in the Undergraduate Research Symposium on Friday, April 5th. The event showcased the diverse research undergraduates conduct at the University of Michigan and CHEPS was proud to have a strong showing. “When speaking with the check-in volunteers, they were amazed at how many posters we, as a collective, were presenting. I immensely enjoyed having the opportunity to speak with others about the BLOCK Scheduling Project and introducing them to one of the many applications of Integer Programming,” said Theodore Endresen, an Industrial and Operations Engineering (IOE) Undergraduate.

Caroline Owens, also an IOE undergraduate, thought the symposium succeeded in showing the breadth of research undergraduates are doing at the University. “I was surprised to recognize many of the other participants who I had not known were involved in research. Hearing about their experiences and the work they had accomplished gave me a greater appreciation for the breadth of the university and all that can be accomplished by undergraduate students,” she said.

Often, CHEPS students are presenting at healthcare or engineering specific events. Lauren Hirth, a Biomechanical Engineering (BME) Undergraduate, enjoyed the chance to connect with undergraduate researchers from a variety of fields. She said, “I enjoyed talking to people about my work that I would normally not talk to at the university, and who did not know about CHEPS. The Symposium was also a great way to see what research other students at the university have been doing, and to catch up with friends I knew from other experiences on campus.”

Riley McKeown, an IOE undergraduate, said, “I was not only able to engage other students by discussing the methodologies of the Shift Scheduling project, but I was also able to tell students from outside of the CoE about CHEPS! While presenting, I ran into old friends I hadn’t seen for a couple of years, it was great to catch up and share our work with each other!”

For Sheridan Tobin, a School of Public Health undergraduate, presenting gave her an important reminder about her research. “Presenting the poster and answering questions was a great reminder of the real-world impact that our project has. It was great to talk with different people who work in healthcare and in other research areas and hear that they were interested in the work we’re doing,” she said.

The following students presented CHEPS work:

CHEPS and Industrial and Operations Engineering (IOE) students Jhawan Davis and Donald Richardson attended the National Society of Black Engineers (NSBE) 45th Annual Convention in Detroit from March 27–31, 2019. According to the NSBE website, “The Annual Convention showcases Black students and professionals who have a passion for science, technology, engineering and math (STEM), who are high achievers in these fields and are channeling their dedication to advance their communities and society at large.”

Both Donald and Jhawan also appreciated how the conference shone a light on Detroit. Jhawan said there were, “over 14,000 attendees roaming around and realizing how amazing the city of Detroit actually is. Additionally, there were over 300 companies who participated in the career fair, hiring the best diverse talent in the country, providing a direct influence on the job market in Detroit, which actually revitalizes the city.”

Jhawan is president of the University of Michigan NSBE chapter, which brought home its 4th consecutive Chapter of the Region award this year. He helped to bring the conference to his hometown of Detroit and found the effort well worth it. “It means a lot,” he said. “I’m excited because, just driving around downtown – I went to high school ten minutes from here – and just seeing different signs like ‘welcome NSBE’ and all the beautiful black people walking around, it’s very exciting. And I’m happy people are getting to see the more positive views of Detroit. We’ve got a reputation for being hard-working. Apparently, our new nickname is the comeback city. I’m glad everybody else is becoming aware of that.”

Donald enjoyed his time working at the University of Michigan recruiting booth. “You’re there talking with prospective students through the entire process from navigating the application process to what students can do now to set themselves up for success in a PhD program. We almost have mini advising sessions. I came from an undergrad program, the Meyerhoff Scholars, that focused on preparing us for pursuing a PhD or MD/PhD, not everyone is fortunate enough to have that. Maybe they’re coming from a school where, as an underrepresented minority, they’re one of two in their program. So they can sometimes feel isolated and not as comfortable to ask questions or be aware obtaining a PhD is in their grasp. NSBE provides a space where you’re with a lot of people that look similar to you, a lot of people that are excelling and genuinely want to see you join them in doing the same. It’s a super friendly environment filled with peers and mentors that are doing everything they can to ensure you get the opportunities they had.”

Donald said that, in addition to taking the time to mentor younger students, he has benefited from the advice of junior faculty and young professionals attending NSBE. “Two years ago, I got advice that if you don’t know what path you’re going in post receiving your PhD regarding faculty vs. industry, make sure you set yourself up to be able to have those options open to you when you make that decision later.” He was especially excited this year to run into IOE and CHEPS alum Brandon Pitts who is now an Assistant Professor at Purdue University as well as other Meyerhoff scholars and professionals helping pave the way for him and many others.

March 29, 2019:

On Friday, March 29th, we were expecting a Lunch and Learn with Mark Van Sumeren at CHEPS. Then we got a pleasant surprise, not just one but two Van Sumerens! Mark, a valued friend of CHEPS who recently moved back to Ann Arbor, brought along his son, Andy. Both Mark and Andy are alums of Industrial and Operations Engineering at the University of Michigan and work in healthcare consulting so they could not be more suited to deliver a CHEPS Lunch and Learn.

Mark is Managing Director of Health Industry Advisor LLC, which “offers health systems, medical device and health care suppliers the requisite critical thinking and expertise to address challenges [in healthcare], head-on.” Andy is a Lean Manufacturing Manager at GE Healthcare and operates his own consultancy.

After Andy and Mark introduced themselves and their work, students had plenty of questions to keep them talking through lunch and beyond. The two were able to provide thoughts on a wide range of topics including the differences between internal and external consulting, how to become an independent consultant, networking, self-promotion, and strategies to keep a project on track. They also told stories of the coolest experiences they’d had while consulting and threw in a few fun family stories, making it both an entertaining and informative lunch.

Andy stressed the importance of getting a wide range of experience and finding opportunities to learn the ins and outs of both internal and external consulting. He stressed that experiencing a project at all stages is the way to grow to be able to handle whatever is thrown at you. “The role you sign up for is not the job description you’ll actually have. The smaller the company, the more hats you’ll wear,” he said.

Mark offered students some solid advice as far as keeping projects on track. He said this starts before the project even officially begins. “The real art is, before accepting the job, really knowing what success is,” he said. He explained this meant not only having a firm understanding of what you want to do and what you’re good at but also defining the scope of the project so you know exactly what you will and won’t do. This also helps maintain your “say/do ratio” so that anything you agree to do, you are sure you can deliver on.

Thank you to Mark and Andy for the visit and the great conversation. We look forward to seeing you in CHEPS again soon!

March 28, 2019:

We were delighted to have a Jim Molloy, long-time friend of CHEPS, visit the Center on March 28th. Jim is a Managing Director heading up the Not-For-Profit Health Care Group at Citi. His over 25 years of experience in the healthcare industry gave him a great deal to discuss with everyone here at CHEPS.

Jim spent his day in mentoring sessions with groups of CHEPS students, discussing CHEPS operations with Associate Director Amy Cohn, and meeting with members of the provider scheduling teams to provide his insights on their work. He was also kind enough to share everything from reading recommendations, job application tips, and career path advice with students.

Justin Rogers, Industrial and Operations Engineering undergraduate, said, “Jim offered great insight into the challenges that healthcare systems are facing, and how the skills of an IOE student can be utilized to solve these challenges.”

Students who will be on the job market soon also got some valuable perspective from Jim. “He was quite helpful in offering advice about ways to distinguish oneself when applying to jobs. I really enjoyed speaking with him and thought that he offered great mentorship in the time that we had together,” said Matthew Levenson, Industrial and Operations Engineering undergraduate.

Hannah Strat, HEPS masters student, also appreciated the chance to learn from Jim’s experience. She said, “Jim provided insight into the variety of industrial engineering career paths within the healthcare sector. We talked about the lifestyle difference between working for a hospital system vs a consulting firm.”

Camille Phaneuf, Neuroscience and Cognitive Science Undergraduate, walked away with some new project management techniques. She said, “Jim offered great insight on effective management styles, emphasizing the need to listen and to implement performance reviews – of oneself and others. In doing so, he explained how these techniques can help individuals and organizations reach their goals. Overall, the conversation was incredibly helpful, and I am excited to apply what I have learned!”

And, finally, Neil Gollapudi, Computer Science undergraduate, walked away with some universal advice. “One major insight I took from him, was that genuine interest often drives success in the field,” he said.

Many thanks to Jim for taking the time to meet with so many CHEPS students and share his experience!

billi lunch and learn
billi lunch and learn
February 25, 2019:

CHEPS students, faculty, and staff met for a Lunch & Learn on Monday to hear about the use of lean thinking from Dr. Jack Billi. Dr. Billi is a Professor in Internal Medicine and Learning Health Sciences (Medical School), Health Management and Policy (Public Health), and Integrated Systems and Design (Engineering) at the University of Michigan. Lean thinking can positively affect the way team members think about problems in a way that improves the quality and efficiency of projects. More specifically, lean thinking involves seeking the root of the problem, separating the root from the goal state, and clearly identifying the gap between the current and future states so that the gap can be taken ownership of and subsequently addressed.

When considering a problem, Dr. Billi encouraged “rotating the gem” to see every face of the obstacle because granularly laying out the problem helps identify team members’ gaps in knowledge and their misunderstandings. In order to apply the lean thinking framework to the ongoing work at CHEPS, we walked through aspects of the Surgical Instruments and Aortic Dissection Intensive Care Unit projects. While doing so, Dr. Billi emphasized going to the (often physical) site of the problem to observe, to learn, and to ask ‘why’ questions. After all, “a problem understood is half solved.”

In sum, CHEPsters enjoyed an informative session of learning how to use the A3 template and lean thinking to mentor problem solving, enabling global thinking, and local action. Thank you, Dr. Billi, for sharing your wisdom!

wiens ihpi talk February 21, 2019:

On Thursday, February 21, Dr. Jenna Wiens spoke to attendees at the Michigan Institute for Healthcare Policy and Innovation’s (IHPI) ongoing research seminar series. Dr. Wiens is a Morris Wellman Assistant Professor of Computer Science and Engineering (CSE) at the University of Michigan and is interested in researching the intersection of machine learning, data mining, and healthcare. In her presentation titled “White Coat, Black Box – Augmenting Clinical Care with AI in the Era of Deep Learning,” Dr. Wiens described the exciting future of machine learning in healthcare as well as the challenges that still need to be tackled.

Dr. Wiens described the troubling circumstances facing the healthcare field in the US including a significant physician shortage, physician burnout, and frequent medical errors in hospitals. Although Dr. Wiens acknowledged that increasing computerization is actually a problem, with doctors using more of their time to enter data, she explained several promising applications of machine learning in healthcare. For example, machine learning can be used to detect patterns that sort a patient from high-risk to low-risk for a particular disease, leading to a decreased length of stay, transmission, costs, and improved outcomes. The question remains, however: “What do we have to do to make artificial intelligence (AI) work in healthcare?”

To address this question, Dr. Wiens expounded on several key principles of deep learning and the current technical challenges of applying machine learning to healthcare. Although these technical challenges remain part of a lively debate among the scientific community, it is clear that these conversations are necessary in order to ensure that AI properly augments clinical care. Dr. Wiens’ work remains at the forefront of developing the infrastructure for the integration of AI into healthcare.

surgical instruments January 24, 2019:

On Thursday, January 24th the Surgical Instruments team presented to over one hundred nursing staff at a Michigan Medicine nursing in-service. These regular meetings serve to keep nurses at Michigan Medicine up to date on the latest procedures, equipment, and research related to their work. The presenters were Abhi Bukkapatnam, LSA undergraduate; Lauren Hirth, BME undergraduate; Michael Kalmus, IOE undergraduate; Emily Krebs, BME undergraduate; and Hannah Strat, IOE/HEPS masters student.

“We presented our experiments, findings, and potential solutions from a project designed to understand and mitigate the fire and burn risks posed by fiber optic cords used in the operating room,” said Michael Kalmus, an IOE undergraduate who is part of the Surgical Instruments team.

The team tested several different fiber optic cords at various light settings with and without safety features such as the Stryker Safelight system and GloShield. Their work initially concentrated on the fire/burn risk that results when fiber optic cords are placed on top of surgical drapes or patients which was the initial hazard identified by Michigan Medicine. However, as they explained in their presentation, the team discovered that fiber optic cords placed near and not in direct contact with patients or drapes can cause fire/burns through the mechanism of radiation. This new understanding regarding the importance of radiation as a hazard substantially influenced the conclusions and recommendations of the group.

“It was a really good experience from start to finish from doing the experiments to concluding with this presentation that had direct impact on Michigan Medicine’s approach to mitigating the risk of fire and patient burn from this hazard,” said Kalmus who has been on the team since last January, around the time when the fiber optic cord research began.
