(1) The effectiveness of disinfection and sterilization must be monitored regularly. The sterilization pass rate must reach 100%, and unqualified items are not allowed to enter the clinical use department.
(2) Disinfectants and sterilants in use: biological and chemical monitoring should be carried out. Biological monitoring: Disinfectants should be monitored once a quarter, and their bacterial content must be less than 100 cfu/mL, and no pathogenic microorganisms should be detected; sterilants should be monitored once a month, and no microorganisms should be detected. Chemical monitoring: Regular monitoring should be based on the performance of disinfectants and sterilants. For example, chlorine-containing disinfectants and peracetic acid should be monitored daily. Glutaraldehyde should be monitored no less than once a week. The disinfection and sterilization effects of disinfected and sterilized items should be monitored at the same time. No pathogenic microorganisms should be detected in disinfected items, and no microorganisms should be detected in sterilized items.
(3) Pressure steam sterilization: process monitoring, chemical monitoring and biological monitoring must be carried out. Process monitoring should be carried out for each pot and recorded in detail. Chemistry monitoring should be performed on each pack, and surgical packs still require central chemical monitoring. Perform B-D test before daily sterilization of pre-vacuum pressure steam sterilizer. Biological monitoring should be carried out every month. New sterilizers must undergo biological monitoring before use and can be used only after passing the test. New packaging containers, placement methods, exhaust methods and special sterilization processes to be used must also be biologically monitored first. Monitor and adopt only after passing the test.
(4) For ethylene oxide gas sterilization, process monitoring must be carried out for each pot, chemical monitoring must be carried out for each package, and biological monitoring must be carried out monthly.
(5) Ultraviolet disinfection. Routine monitoring, UV lamp irradiation intensity monitoring and biological monitoring should be carried out. Daily monitoring includes lamp application time, cumulative exposure time and user signature. The irradiation intensity of new and in-use UV lamps should be monitored. The irradiation intensity of new lamps should not be less than 100?W/cm2, and that of lamps in use should not be less than 70?W/cm2. The irradiation intensity should be monitored every six months. once. Biological monitoring is carried out when necessary. Natural bacteria in disinfected items or air should be reduced by more than 90.0%, and the killing rate of artificially contaminated bacteria should reach 90.0%.
(6) Various disinfected endoscopes (such as gastroscopy, colonoscopy, laryngoscope, bronchoscope, etc.) and other disinfected items: should be monitored every quarter, and no pathogenic microorganisms should be detected. Various sterilized endoscopes (such as laparoscopy, arthroscopy, choledochoscopy, cystoscopy, thoracoscopy, etc.), biopsy forceps and sterilized items must be monitored monthly and no microorganisms may be detected.
(7) Blood purification system: Dialysis water and dialysate must be monitored monthly. When there is suspicion of dialysate contamination or serious infection cases, additional sampling points should be added, such as raw water inlets, softened water outlets, reverse osmosis water outlets, dialysate dispensing outlets, etc., and timely monitoring should be carried out. When the inspection results exceed the specified standard value, re-inspection must be carried out. The standard values ??are: the total number of bacterial colonies in the dialysis water must be ?200cfu/mL, and the total number of bacterial colonies in the dialysate must be ?2000cfu/mL, and pathogenic microorganisms must not be detected.
