Abstract：Objective Based on the expectation theory framework,design a scientifically reasonable surgical performance evaluation plan,optimize the doctor incentive mechanism,and improve the hospital's surgical related performance operation and management level.Method Through in-depth interviews with insiders,it fully explored the existing problems in surgical performance evaluation.Based on this,it constructed a"four-level,nine-grade"performance scheme based on the clustering of surgical difficulty index and the calculation of performance ratio.It tested the effectiveness of the new scheme by calculating the Karensky-Harabasz index and within-cluster sum of squares for the new and old schemes,and designed a questionnaire to consult clinical departments.Result Simulations showed that the scheme could more reasonably distinguish and compensate for surgeries with different resource consumption and difficulty levels,which helped to exert the guiding role of performance and effectively improve the hospital's ability to perform high-difficulty surgeries,while also helping clinical departments form a sense of resource control.Conclusion When conducting surgical performance evaluation,it is necessary to balance the expectations of medical staff in clinical departments with the needs of hospital performance operational management.Through reasonable scheme setting,application of supporting control measures,and timely dynamic adjustments,appropriate incentives can be achieved,providing a more scientific path for hospital surgical performance management.
