Objective To construct a comprehensive discharge planning evaluation index system for senile patients, and to comprehensively evaluate hospital discharge related information and medical care needs of senile patients. Methods Delphi method was used to establish the indicators of discharge planning evaluation index system for senile patients, and to test its reliability and validity. The weights of the indicators at different levels were determined by analytic hierarchy process. Results The comprehensive discharge planning evaluation index system for senile patients included 3 first-level indexes (general situation evaluation, physical and mental evaluation, discharge management), 9 second-level indexes and 33 third-level indexes.The response rates of the two rounds of expert consultation were both 100%, the authoritative coefficients were 0.847 and 0.850, the coordination coefficients were 0.165 and 0.257, respectively (all P＜0.01). Cronbach′s α of the index system was 0.869, I-CVI ranged from 0.667 to 1.000, S-CVI/Ave was 0.935, and the CR values of the index at all levels were＜0.1. Conclusion There was unanimous agreement over the comprehensive discharge planning evaluation index system for senile patients amongst experts.The results were scientific and reliable. The index system enjoyed good internal consistency reliability and content validity,which can provide basis for development of comprehensive discharge plan service.
