Objective:To construct an evaluation index system for the quality of physical constraint care for elderly patients, providing a reference basis for clinical evaluation of the quality of physical constraint care for elderly patients, so as to reduce the rate of physical restraint in elderly patients.Methods:Based on the three-dimensional quality model of "structure-process-outcome", combined with literature review and theoretical analysis, a preliminary draft of an evaluation index system for the quality of physical constraint care for elderly patients was established. From May to August 2022, 17 experts were selected by convenience sampling for Delphi consultation. The evaluation indicators and their weights for the quality of physical restraint care for elderly patients were determined using the analytic hierarchy process.Results:Two rounds of consultation were conducted, and the effective response rates of the questionnaire were 88.24% (15/17) and 100.00% (15/15) , respectively. The expert authority coefficients were 0.97, and the Kendall harmony coefficients were 0.34 and 0.39 ( P<0.05) . The final evaluation index system for the quality of physical constraint care for elderly patients included 3 first-level indicators, 15 second-level indicators, and 34 third-level indicators. Conclusions:The content of the evaluation index system for the quality of physical restraint care for elderly patients constructed in this study is scientific, reliable, comprehensive, and targeted, which can provide a reference basis for measuring the quality of physical restraint care for elderly patients.
