Objective By exploring the conditional configuration effect of negative defensive medicine behavior,the formation mechanism and causal path of negative defensive medicine are explained,and systematic suggestions are provided for negative defensive medicine behavior,so as to improve the rational utilization of health resources.Methods NCA and fsQCA are used to conduct configuration analysis on factors influencing passive defensive medical behavior,output the conditional configuration,and further analyze the configuration effects among the influencing factors.Results The antecedent conditions of negative defensive medicine include systemic mechanisms,institutional norms,social culture,doctor-patient relationships,and self-efficacy.Ultimately,two paths contributing to passive defensive medical behavior emerge:environment conduction type and efficiency-environment joint conduction type,their consistency is 0.830.Conclusion To reduce the negative defensive medical behavior,it should pay atten-tion to improving the institutional environment and improving doctors'self-efficacy,establish a fair and reasonable external institutional environment,create an honest and harmonious cultural atmosphere,strengthen the training of doctors'professional ability and improve the doctor-patient relationship,so as to improve the rational use of health resources.

Objective To understand the status of behavioral intentions of defensive medical treatment in medical students,and explore the relationship between practice environment and behavioral intentions of defensive medical treatment.To provide reference for reducing the tendency of defensive medicine(DM)behavior of medical students and improving the negative effects of DM.Methods A web-based questionnaire survey was conducted among medi-cal students in four medical colleges in Heilongjiang Province.The structural equation modeling of the relationship be-tween practice environment and behavioral intentions of defensive medical treatment in medical students was con-structed by Amos 26.0 software.Results The mean score of medical students'behavioral intentions of positive and negarive defensive medical treatment was 44.49-6.90 and 20.06-6.83,respectively.The behavioral intention of posi-tively defensive medical treatment was positively associated(β=0.892,P＜0.05)with cognition of doctor-patient relationship.While the behavioral intention of negative defensive medical treatment was positively correlated(β=0.403,0.343,P＜0.05)with environment cognition,perception of risk and negatively correlated(β=-0.726,P＜0.05)with cognition of doctor-patient relationship.As an intermediary variable,the direct and indirect effects of cog-nition of doctor-patient relationship on negative defensive medical behavior tendency were-0.470 and 0.043,the difference was statistically significant(P＜0.05).Conclusion Improving cognition of medical students'doctor-pa-tient relationship is beneficial to understand defensive medical treatment for medical students.The negative defen-sive medical behavior tendency of medical students should be reduced by reducing their negative cognition of environ-ment or improving their cognition of doctor-patient relationship.
