Non-emergency Patient Transfer Scheduling and Assignment

Emergency Medical Services organizations are responsible for providing paramedic crews, vehicles and equipment to transfer patients from one location to another in emergency and non-emergency settings. They must solve difficult scheduling and assignment problems to ensure on-time arrival of patients and the efficient use of health care resources during non-emergency operations. Ambulances can serve both emergency and non-emergency requests but are rarely available to serve non-emergency requests. Therefore, non-emergency requests are the responsibility of Patient Transfer Units. The objective of this study is to develop a mathematical model that will assign Patient Transfer Units to non-emergency patient transfer requests, design a schedule that will minimize travel costs and balance workloads and apply it to a real-world case study. This paper also proposes a framework to utilize historical patient transfer data in the scheduling process. The mathematical model provides decision support for the non-emergency patient transfer scheduling process.
