Operations Research performs research into the development and implementation of quantitative methods to reduce peri-operative costs. Techniques involving discrete-event and Monte-Carlo computer simulation, operations research, and statistical analyses of discharge and operating room databases are used to study the mathematics and economics of operating room efficiency, staffing, scheduling, workload, case duration predictions, etc. We work with hospitals, anesthesia groups, and industries worldwide to help them implement the latest methods for efficient delivery of operating room and anesthesia services.
