A key exchange system for secure data coordination in healthcare systems

Abstract

To explore the coordination problem of the “gatekeeper” medical system, a referral game model between general hospitals and community hospitals within the system was established. Two non-competitive and competitive systems methods were modeled. The optimal referral threshold strategy and contract form under the service payment contract cooperation model. The conclusion shows that reducing the service cost of unit personnel in the system can effectively improve the system utility. Introducing competition can reduce the referral rate and promote the first consultation in community hospitals. The service payment contracts of non-competitive and competitive systems under different scales are feasible to achieve system coordination. The coordination efficiency of small-scale settings in competitive strategies is higher than that of large-scale environments. In the design of medical systems, competition cannot be avoided. Existing, setting up multiple small competing hospitals can bring higher social efficiency.
