On-site investigation of endoscope final rinsing water management in 94 medical institutions in Shanghai
OBJECTIVE To investigate the management status of final rinsing water in endoscopy centers of various levels of medical institutions in Shanghai.The findings will provide a basis for improving water quality,establis-hing quality control standards,and implementing regulatory measures.METHODS During the Shanghai hospital infection quality control inspection in 2023,on-site research was conducted on the management of final rinsing wa-ter in the endoscopy centers of the inspected medical institutions.The research included the management of final rinsing water,sampling and testing methods and waterway disinfection methods.RESULTS Among the 106 medi-cal institutions under inspection,94 hospitals were equipped with endoscopy centers.Less than 30％of the medical institutions independently cleaned and disinfected diagnostic and therapeutic endoscopes in separate areas,and ap-proximately 15％of the endoscopy centers lacked independent purified water treatment systems.The proportions of using purified water in final rinsing were 85.7％,87.8％,and 90.9％in tertiary hospitals,secondary hospitals,and privately-run hospitals,respectively.The investigation found that 78.6％of tertiary hospitals,51.2％of sec-ondary hospitals,and 81.8％of privately-run hospitals conducted monthly sampling and monitoring of final rinsing water(P＜0.05).The proportions of disinfecting pipelines by chlorine-based disinfectants were 14.3％,22.0％,and 18.2％in each level,and the proportions of using R2A agar plate for culture detection of purified water were 35.7％,36.6％,and 27.3％,respectively,with no significant difference among different levels of hospitals.CONCLUSION The current status of endoscope water management in Shanghai is not optimistic,including insuffi-cient cognition of management personnel,inadequate hospital attention,inconsistent clinical implementation,and insufficient regulatory efforts.Targeted training should be carried out in the future to reduce the risk of infection.
