Objective To construct the nursing sensitive quality index system for interventional treatment of trigeminal neuralgia,so as to provide reference for the nursing quality evaluation and management of interventional treatment of trigeminal neuralgia.Methods From June to December 2022,using the"Structure-Process-Results"quality evaluation model as the theoretical framework,an expert inquiry questionnaire was developed based on literature review.The indicator system was established using the Delphi method,and the weights of the indicators were determined using the analytic hierarchy process.Results The recovery rates of the two rounds of expert correspondence questionnaires were 92.6%(25/27)and 100.0%(25/25),the expert authority coefficients were 0.860 and 0.888,the Kendall's coordination coefficients were 0.073 and 0.058(P<0.05),and the coefficient of variation were 0-0.330 and 0-0.191,respectively.Finally,the nursing sensitive quality index system for interventional treatment of trigeminal neuralgia was formed,which included three primary indexes,14 secondary indexes and 54 tertiary indexes.Conclusions The index system has strong scientific and clinical applicability,which can provide reference for nursing quality evaluation and management of interventional treatment of trigeminal neuralgia.
