智慧医疗信息平台中医患合作机制——基于演化博弈与突变视角

Mechanism of Doctor-Patient Cooperation in Smart Medical Information Platform:Analysis from the Perspective of Evolutionary Game and Catastrophe

为分析智慧医疗信息平台中医患合作行为,构建演化博弈模型,引入随机干扰因素表示平台信息的不确定性;其后将医患随机演化博弈模型转化为尖点突变模型,证明医患行为演化中暗含突变机理;最后,用仿真分析诊疗型和互动型信息平台中医患行为的演化与突变机制.研究发现:在智慧医疗信息平台中,医患行为选择可能因感知价值和随机干扰等因素而突变;当医患初始合作概率高时,若信息平台安全与可靠性差,医患倾向于不合作;当医患初始合作概率低时,若信息平台安全与可靠性高,医患倾向于合作;当医患初始合作概率处于中等水平时,医患更容易受不合作额外收益影响,其行为选择突变概率更高.研究结合演化博弈论与突变理论,深入分析智慧医疗信息平台中医患合作机制,结论为信息平台中的医患合作行为研究提供启示.

To analyze the cooperation behavior from the perspective of doctors and patients in the smart medical information platform,this paper constructs a random evolutionary game model and introduces random interference factors to represent the information uncertainty in the information platform.Afterward,this paper transforms the stochastic evolutionary game model of doctors and patients into a cusp catastrophe model through the limit probability density function,proving that the sudden change mechanism is implied in the behavior evolution of doctors and patients.Finally,the simulation method is used to analyze the evolution and sudden change mechanism of the behavior selection of doctors and patients in the diagnostic information platform and the interactive information platform.This paper finds that:In the smart medical information platform,the behavior selection of doctors and patients may change drastically due to factors such as perceived value and random interference;When the initial cooperation probability between doctors and patients is high if the security and reliability of information platform are poor,doctors and patients tend not to cooperate;When the initial cooperation probability is low if the information platform security and reliability are good,doctors and patients tend to cooperate;When the initial cooperation probability is at a moderate level,the behaviors of doctors and patients in the information platform are more susceptible to the additional benefits of non-cooperation,sudden changes of behavior selection are more probable.This paper analyzes the cooperation mechanism between doctors and patients in the smart medical information platform by combining evolutionary game theory and cusp catastrophe theory.It explains the reasons for sudden discontinuous changes in the behavior state of doctors and patients.The conclusion provides enlightenment for the research on doctor-patient cooperative behavior in the information platform and the development of the smart medical platform.
