Friday, September 16, 2016 12:00 PM – 1:00 PM Mechanical Engineering Rm 1153 Light refreshments will be served! Fall 2016 Colloquium Series Elective Surgery Scheduling Considering Time-Dependent Patient Health Conditions Presented by Dr. Yuehwern Yih, Ph.D. Associate Director, Regenstrief Center for Healthcare Engineering Professor, School of Industrial Engineering, Purdue University Surgery is estimated to account for approximately 40% of a hospital’s total revenues and expenses. The quality of elective surgery scheduling directly affects patient outcomes, safety, access, healthcare cost, as well as hospital’s operating costs. The common objectives are to minimize patient wait time and hospital overtime. In this research, we propose an operating room planning problem that considers daily patient health condition. In addition to patient health condition, operating room overutilization is also considered to reduce a hospital’s surgical costs. We formulated the problem as a stochastic MIP and employed the sample average approximation to identify the optimal assignment of surgeries. Numerical results based on a block scheduling case will be discussed. About the Speaker: Dr. Yuehwern Yih received her Ph.D. from UW-Madison. Dr. Yih is a Professor of Industrial Engineering at Purdue and her expertise resides in system and process design, modeling, monitoring, and decision making to improve its quality and performance. She is also the Associate Director of Regenstrief Center for Healthcare Engineering in Discovery Park at Purdue. Dr. Yih provides strong leadership in infusing system engineering in healthcare services, and coordinating strategic research initiatives and programs for the Center. Her Handbook of Healthcare Delivery Systems is the first handbook that connects wide arrays of healthcare related sectors to provide a holistic view of healthcare delivery process as an integrated system. Dr. Yih is one of the experts who contributed to “Order from Chaos – Accelerating Care Integration,” a report of the Lucian Leape Institute Roundtable in 2012. In 2013, Dr. Yih received the inaugural Faculty Engagement Fellow Award at Purdue, based on her work at AMPATH developing a nutrition information system and a food distribution system for HIV patients in Western Kenya. She is a NEC Faculty Fellow, IISE Fellow, and ELATE Fellow.
