Abstract: Objective: To construct an objective and scientific evaluation index system for risk factors of cleaning, disinfection and sterilization of precision instruments in the Central Sterile Supply Department (CSSD). Methods: Based on the risk management theory, a evaluation index system for risk factors of cleaning, disinfection and sterilization of precision instruments in CSSD was developed through mainly literature analysis, and semi-structured interviews. Two rounds of expert consultation with 20 experts were conducted from July to August 2022 using the Delphi method to establish the index system. Results: The effective recovery rate of the 2-round Delphi consultation questionnaire was 100.00%. Expert authority coefficient values were 0.94 on both rounds. Kendall's harmony coefficients were 0.258 and 0.207 (P<0.001). The final index system included 6 primary indicators and 42 secondary indicators. Conclusion: The evaluation index system for risk factors of cleaning, disinfection and sterilization of precision instruments in CSSD is highly reliable and scientific and can provide a reference basis for the formulation and implementation of countermeasures against the risk factors of cleaning, disinfection and sterilization of precision instruments in CSSD.
