Abstract: Objective To construct a quality evaluation indicator system of analgesia and sedation care in adult ICUs，and to provide a reference standard for monitoring and management of nursing quality of analgesia and sedation in adult ICUs. Methods From February to November 2022，the content and weights of quality evaluation indicators of analgesia and sedation care in adult ICUs were determined by using literature review，expert meeting method，Delphi method and analytic hierarchy method based on the three-dimensional “structure-process-outcome” quality model. Results The effective recovery rates of 2 rounds of questionnaires were 100% and 92% ，the authority coefficients were 0.87 and 0.88，the variation coefficients were 0.04～0.32 and 0～0.21，and the Kendall harmony coefficients were 0.245 and 0.260. The final quality evaluation indicator system of analgesia and sedation care in adult ICUs included 3 first-level indicators，11 second-level indicators and 45 third-level indicators. Conclusion The quality evaluation indicator system of analgesia and sedation care in adult ICUs has high Scientificity and reliability，reflects professionalism and specificity，and has a reference value on evaluating the nursing quality of analgesia and sedation in ICU.
