Abstract：Objective To understand the cleaning and disinfection status of endoscope room in Beijing hospitals. Methods From March to August 2021, questionnaire survey method with convenient sampling was adopted to investigate the layout facilities, system construction, training, occupational safety protection, cleaning and disinfection (sterilization) process, monitoring, and recording of endoscopy centers (rooms) in 42 tertiary hospitals in Beijing. Results A total of 42 questionnaires were collected, with an effective recovery rate of 100%. Among them 10 institutions had no office room, 12 institutions had no anesthesia recovery room, and 6 institutions had no emergency plan, and there was still a big gap in training. The cleaning and disinfection tank was fully equipped, power pump and ultrasonic cleaner are 76.2% and 69.0% respectively, and 73.8% of the endoscopic automatic cleaning machines were configured. 30.9% of hospitals were equipped with ethylene oxide sterilizers, 9.5% with low temperature formaldehyde sterilization, and 59.5% with hydrogen peroxide low-temperature plasma sterilizers. Phthalaldehyde was used in 59.5% of hospitals, and compound chlorine-containing disinfectant was used in 40.5% of hospitals. 42 hospitals had provided protective equipment for disinfection workers. Natural ventilation was used in 15 hospitals (35.7%), and mechanical ventilation was installed in 27 hospitals (64.3%), and 5 (18.5%) of the installation locations were on the ceiling, which did not meet the requirements. There were still some gaps in the pretreatment, leak detection, flushing water and equipment. Conclusion All medical institutions are able to comply with the basic requirements of standardized cleaning and disinfection. However, there are still some gaps in the configuration of facilities and equipment and the implementation of cleaning and disinfection details. Medical institutions should constantly improve against the new norms to reduce the incidence of nosocomial infections.
