Control of costs and quality of patient care are both important concerns for healthcare systems. Improved management of supplies and instruments for operating rooms provides an opportunity to reduce costs while still maintaining the current level of patient care. Operating rooms are a main cost center within hospitals and previous research has shown that improved management of disposable supplies and sterile instruments, which are requested by surgeons through preference cards, provides an opportunity for significantly reducing surgical costs. Primarily, this means not opening or exposing items that aren’t needed, which requires the items to be disposed or resterilized, even if they haven’t been used. Additional improvements can be achieved by reducing duplication of instruments in inventory due to the variations in preference cards. In this research, various optimization models and solution methods are developed for managing surgical supplies and sterile instruments. The optimization models deal with the decision of configuring trays of instruments, as well as determining the quantity of surgical supplies to be stored in different locations in such a way that ensures: (1) surgeons’ requirements are met, (2) inventory and reprocessing costs are minimized. The models also captures historical usage pattern of instruments and supplies and allow surgeons to make better decisions about the items included on the preference cards, and which items can be opened at the time of need as opposed to being opened before a procedure.
