Abstract: Objective: To investigate the use of out-of-hospital disinfection supply services in medical institutions, grasp the key links of disinfection supply management, and provide scientific basis and reference for the implementation of the basic standards and management norms in Chinese Central Sterile Supply Department. Methods: In 2021, a questionnaire survey was conducted among 506 medical institutions in China that use out-of-hospital disinfection supply services by means of target sampling. Results: Totally 49.8%(252) of the medical institutions chose the disinfection supply service provided by nearby hospitals, and 50.2% (254) of the medical institutions chose the disinfection supply service to choose the disinfection supply center. The highest proportion of sterilized instruments sent out of hospital was "conventional surgical instruments", 69.4% (351). The implementation rate of all requirements in the national health industry standard for out-of-hospital disinfection supply services in public medical institutions at all levels was 59.2% to 92.2%, and the difference was statistically significant among different levels of public medical institutions (P<0.05). Conclusion: The overall management level of out-of-hospital disinfection supply service in medical institutions needs to be improved. Quality management and management of full-time disinfection supply personnel should be strengthened, and a temporary storage room for collecting contaminated devices and a room for handing over and distributing sterilized items should be set up reasonably. It is recommended that when revising the hygiene industry standards for disinfection supply centers, medical institutions with a large volume of cleaning and disinfection prioritize establishing self-built disinfection supply centers to ensure the timely and secure reprocessing of medical instruments.
