Abstract:Objective：To build a quality evaluation system for “Internet+nursing service” based on a three-dimensional structure of medical institutions. Methods：Based on the theoretical framework of “structure-process-result” proposed by Donabedian，a pool of quality evaluation indexes was initially constructed based on literature search，semi-structured interview and field research，and the evaluation index system was determined through two rounds of Delphi expert consultation. Results：The positive coefficient of the two rounds of experts was 100%，the authority coefficient was 0.90，and the Kendall coefficient of the two rounds of expert correspondence was 0.283 and 0.266（P < 0.05），respectively，with high consistency. Finally，an Internet+nursing service quality evaluation system with 3 first-level items，11 second-level items and 57 third-level items was formed. Conclusions：The content of the medical institution-led Internet+nursing service quality evaluation system based on the three-dimensional structure is reasonable，and the construction process is scientific，which can provide a reference basis for the evaluation of Internet+nursing service quality of medical institutions in China.
