Health Care Operations

Rising healthcare expenditures across the world and a changing attitude of patients are forcing a radical change in the way healthcare delivery is organized. This rises many challenges for researchers from the operations research/operations management community, who have shown a steeply increased attention in recent years. Using mathematical models and techniques, complex healthcare delivery processes are analyzed and optimized. Within the CHOIR research group of University of Twente, a lot of work is done within this domain, based on an extensive collaboration with the healthcare sector. Our research focus has shifted from the optimization of key hospital resources like operating theatres and radiology equipment to optimization of the entire care pathway. I will introduce CHOIR, present an overview of our studies, not only pertaining to the operating theatre, but also including preceding and succeeding departments, and addressing all hierarchical levels of control. I will also discuss how we strive to let our research result in actual implementation of the outcomes, in order to improve productivity, quality of care, and quality of labor.
