Objective:To construct the evaluation index system of peritoneal dialysis nursing quality, so as to provide a basis for management and evaluation of peritoneal dialysis nursing quality.Methods:Through literature review and expert interviews, the peritoneal dialysis nursing quality evaluation index system (draft) was initially determined on the evidence-based basis. The expert letter questionnaire was designed, and indexes of nursing quality evaluation were screened and revised by Delphi expert letter questionnaire and boundary value method. The analytic hierarchy process was used to determine the weight of evaluation indexes, and the evaluation system of the peritoneal dialysis nursing quality index was established.Results:The expert response rates of 2 rounds of questionnaires were 91.43% and 85.71%, and the expert authority coefficients of the 2 rounds were respectively 0.838 0 and 0.862 2, and the coordination coefficients of the first, second and third levels of indexes of the second round were respectively 0.643, 0.431 and 0.283 ( P<0.01) . The final evaluation index system included 3 first-level indicators, 18 second-level indicators and 84 third-level indicators. Conclusions:The evaluation index system of peritoneal dialysis nursing quality has good reliability and applicability. After further verification, it can be used as an evaluation tool of peritoneal dialysis nursing quality management.
