Objective To explore and construct an indicator system for performance appraisal in operating room nurses of cancer hospitals,in order to provide references for performance management.Methods From May to December 2022,the four-dimensional model of individual performance was used as the theoretical framework,and the research was carried out by literature research method,focus group interview method,Delphi expert consultation method and analytic hierarchy process,to establish the content of the performance appraisal index system of operating room nurses in cancer hospitals and the weight of each index.Results After 2 rounds of expert correspondence,29 questionnaires were sent out and 27 returned in the first round,with an expert positive coefficient of 93.10％;27 questionnaires were sent out and 27 returned in the second round,with an expert positive coefficient of 100％;expert authority coefficient of the first round was 0.941 and the second round was 0.937.In the first round,the variation coefficient of each index was 0-0.249,and the coordination coefficient was 0.201-0.352;in the second round,the variation coefficient of each index was 0-0.204,and the coordination coefficient was 0.275-0.407.Finally,a performance appraisal index system of operating room nurses in cancer hospitals was formed,which consisted of 4 first-level indicators,including task performance,interpersonal performance,adaptive performance and effort performance,11 second-level indicators and 54 third-level indicators.Conclusion The indicator system for performance appraisal in operating room nurses of cancer hospitals constructed in this study is reliable and scientific,specialized and applicable,and it can provide references for performance management.
