Abstract: Objective To understand the basic status of disinfection supply centers in secondary and above medical institutions in Taiyuan region, and to provide reference suggestions for further improving the construction standard of disinfection supply. Methods Using random sampling survey method, 43 secondary and above medical institutions in Taiyuan region were selected as the research subjects. A combination of questionnaire survey and on‐site survey was used to complete the survey on the current management status of disinfection supply centers in medical institutions. The descriptive analysis method was used to analyze the survey results. Results A total of 43 secondary and above medical institutions were surveyed, of which 24 were secondary hospitals and 19 were tertiary hospitals. Among the 43 medical institutions, 16 （37.21%） were located as independent disinfection supply centers. There were 34 medical institutions under centralized management, accounting for 79.07%; There were 15 medical institutions with unclear layout, accounting for 34.88%. There were 9 and 19 medical institutions with cross or countercurrent cleaning channels and polluted surrounding environment, accounting for 20.93% and 44.19%, respectively. There were 817 staff in 43 medical institutions, including 504 in tertiary hospitals and 313 in secondary hospitals. The staff positions were mainly nurses, accounting for 73.81%. The education and professional titles were mainly junior college and below and primary, accounting for 74.91% and 66.34%, respectively. And then, 51.29% of the staff had worked for less than 5 years. The configuration rate of facilities and equipment in tertiary hospitals was high, and the proportion of some facilities and equipment in secondary hospitals, such as ultrasonic cleaning device, low temperature sterilizer, and insulation detector, was low. There were only 16 medical institutions using the information quality traceability system, accounting for 37.21%. Conclusions There are some problems in the disinfection supply centers of secondary and above medical institutions in Taiyuan region, such as unreasonable building layout, insufficient hardware and software equipment, low professional level of staff, unimplemented centralized management, and inadequate traceability of information quality. Management should be strengthened to improve the quality of disinfection and sterilization.
