Research on the Motivation of Information Sharing among Medical Institutions under the Condition of Service Quality Differentiation
摘要
Abstract
In recent years,the continuous growth of the global population and the intensification of the aging trend have increased the demand for medical resources.The emergence of new diseases and the increasing burden of chronic diseases have further challenged the medical system.To address these issues,countries have been promoting healthcare reform policies aimed at improving the quality and efficiency of medical services,ultimately safeguarding the health rights of citizens.A key aspect of this reform is the sharing of medical information,which is considered to improve the efficiency of resource utilization and reduce the imbalance in resource allocation. Medical information sharing includes electronic medical records,inter-institutional information exchange and medical research data sharing.A unified platform facilitates information exchange across regions and institutions,enabling medical staff to access comprehensive and timely patient health information,thereby improving the accuracy of diagnosis and treatment.In addition,medical information sharing also helps to optimize the allocation of medical resources.By analyzing medical data nationwide,it is possible to better understand the distribution of diseases and medical needs in various regions,thereby allocating medical resources more rationally,improving the efficiency of resource utilization,and alleviating the problems caused by the imbalance of medical resources between regions. However,due to concerns about privacy breaches and potential revenue losses for hospitals,hospitals and patients show limited enthusiasm for medical information sharing.To address this issue,we have constructed a multi-stage duopoly dynamic game model to explore the factors influencing the participation of hospitals and patients in information sharing.Given two competing public hospitals,A and B,patient decisions are influenced by the perceived net utility of service quality,price and travel costs.Although service prices are set by social planners,hospitals decide on service qualities to maximize their own payoffs. Our study analyzes the service quality decisions of hospitals at multiple patient care stages,considering multi-stage treatment.At the same time,it examines the impact of information sharing on hospital decision-making,benefits and social welfare,exploring the dynamic strategic evolution of hospitals in information sharing.Key findings include:First,health examination costs significantly influence hospital decisions.Lower costs or higher marginal service costs increase the hospital's inclination towards information sharing,indicating that reducing health examination costs can foster a more conducive economic environment for sharing.Service quality decisions depend on specific circumstances.When marginal service costs are low,hospitals participating in information sharing set higher service quality in the first stage than under non-sharing scenarios.Second,for patients not transferred in the second stage,information sharing is more likely to bring about higher service quality,while for transferred patients,not sharing is more likely to bring about higher quality.This emphasizes the complex relationship between service quality and information sharing strategies.Additionally,comparing the benefits of hospitals and social planners with and without information sharing shows that when hospitals share information,social planners tend to set higher service prices,potentially compensating hospitals for revenue losses.However,excessively high prices may dampen patient enthusiasm for sharing,hindering its development.Therefore,while ensuring the economic benefits of hospitals,it is also necessary to consider the interests of patients and find a balance.Moreover,the study shows that when marginal service costs are low or health exami-nation fees are not too high,both social planners and hospitals are inclined to medical information sharing,at which point the interests between social planners and hospitals can be aligned. In conclusion,medical information sharing is crucial for improving resource utilization and mitigating alloca-tion disparities.However,limited enthusiasm from hospitals and patients hinders its progress.By understanding hospitals' and patients' decision-making mechanisms through a dynamic game model,social planners can implement incentive measures,fostering greater hospital cooperation to advance medical information sharing.关键词
