Résumé
The aim of this study was to assess the practices of health care workers during gasterointestinal endoscope reprocessing, evaluate their knowledge about reprocessing, and verify their compliance with laboratory and microbiological tests in endoscopy units at Zagazig University and Fayoum University hospitals. All nursing staff on duty from 10 endoscopy units, with 16 flexible endoscopes, were included. Knowledge and practice were assessed by a questionnaire and a checklist. The mean knowledge score was 7.5 [SD 1.9], which was poor. Compliance was 90% for disinfection and 74% for endoscope processing after disinfection. Before reuse after cleaning, no organisms were detected in 5 endoscopes, while 8 colony forming units were found in 2. Pseudomonas aeruginosa was the most common organism isolated. Strict implementation of the reprocessing guidelines are needed, especially the pre-cleaning stage and leak testing. Repeating high level disinfection after storage and before use must be followed
