Study of Major Risk Factors Analysis and Prevention Measures of Infection in Endoscopic Cleaning and Disinfection / 现代生物医学进展

ABSTRACT

Objective:To summarize the major risk factors of infection in the process of cleaning and disinfection of endoscopy center in our hospital,and formulate the corresponding prevention measures to reduce the incidence of endoscopic infection so as to ensure medical safety of patients.Methods:The specialist check the cleaning disinfection process,statistics of each link in the risk factors of infection.600 endoscopes were taken at random after disinfection,endoscopic inner cavity and the outer surface samples are collected,the cleaning and disinfection of the test results for evaluating quality indicators.Results:Testing 600 samples of qualified 584,and the percent of pass is 97.3％,gastroscopy,colonoscopy,duodenum mirror,bronchoscope,endoscopic ultrasonography qualified rate was 98.6％,96.8％,95.6％,96.0％,97.2％,respectively.28 strains of pathogenic bacteria were detected in 16 cases of unqualified samples,including 13 strains of helicobacter pylori,7 strains of escherichia coli,4 strains of pseudomonas aeruginosa,2 strains of pseudomonas aeruginosa,1 strains of staphylococcus aureus,1 strains of Klebsiella pneumoniae;16 cases to detect unqualified reason analysis,scrub incomplete accounted for 37.5％,Not according to the instructions required to use multi-enzyme and disinfectant accounted for 18.75％,special infected patients did not do special treatment of endoscopy accounted for 12.5％,endoscopic insufficient drying and the staffhand hygiene is not up to standard accounted for 12.5％,respectively.Conclusion:Endoscopic cleaning and disinfection aspects of infection caused by many factors,infection control education should be strengthened for all personal in the endoscopy center,regular professional training of cleaning and sanitation personal,cleaning and disinfection process should be standardized management,establish traceability registration system,control the quality of the endoscope cleaning and disinfection from each link.It is the main measure to prevent digestive endoscopy center in infection.
