ObjectiveTo construct the terminology standard of hospital quality and safety. MethodsThe draft terminology standard was constructed through group discussions, and the final draft terminology standard was formed after one round of Delphi expert consultation and two rounds of expert consensus meetings. ResultsThe recovery rate of the questionnaire was 100%, and the authority coefficient of experts was 0.87. A total of 15 experts were invited to two rounds of expert consensus meetings. The terminology standard for hospital quality and safety (TCHAS 10-1-1-4—2022) was finally released, including 4 first-level categories, 20 second-level categories, and 370 terms in total. ConclusionThe terminology standard of hospital quality and safety developed in this study is scientific and reliable, which can be used as a tool to assist medical institutions in carrying out standardized management.
