“Length-of-Stay and Optimal Portfolio of Surgical Procedures”
In this study we provide analytical insights on how to optimally allocate hospital operating capacity
between various types of elective surgical procedures. Our focus is on the interaction between
utilizing hospital beds and operating room capacity which are the major constraining resources. In
our model, each procedure type has an associated revenue, deterministic case duration, and
stochastic length of stay which is the time it takes for patients to recover and leave the hospital; we
consider arbitrary distributions for length of stay in this paper. The surgeries performed today affect
the availability of hospital beds for the following days in this setting. We describe the optimal mix of
procedures in the presence of a service-level constraint on hospital beds, an operating room capacity
constraint, and procedure demand constraints.
This is a joint work with Hessam Bavafa and Prof. Sergei Savin.
