          There is a growing emphasis on quality management in endoscope reprocessing. Previous surveys conducted in 2002 and 2004 were not practitioner-oriented. Therefore, this survey is significant for being the first to target actual participants in endoscope reprocessing in Korea.


          This survey comprised 33 self-filled questions, and was personally delivered to nurses and nursing auxiliaries in the endoscopy departments of eight hospitals belonging to the society. The anonymous responses were collected after 1 week either by post or in person by committee members.


          The survey included 100 participants. In the questionnaire addressing compliance rates with the reprocessing guideline, the majority (98.9%) had a high compliance rate compared to 27% of respondents in 2002 and 50% in 2004. The lowest rate of compliance with a reprocessing procedure was reported for transporting the contaminated endoscope in a sealed container. Automated endoscope reprocessors were available in all hospitals. Regarding reprocessing time, more than half of the subjects replied that reprocessing took more than 15 minutes (63.2%).


          The quality management of endoscope reprocessing has improved as since the previous survey. A national survey expanded to include primary clinics is required to determine the true current status of endoscope reprocessing.

          Transmission of infection by gastrointestinal endoscopy and bronchoscopy.

          To review reports on the transmission of infections by flexible gastrointestinal endoscopy and bronchoscopy in order to determine common infecting microorganisms, circumstances of transmission, and methods of risk reduction. Relevant English-language articles were identified through prominent review articles and a MEDLINE search (1966 to July 1992); additional references were selected from the bibliographies of identified articles. All selected articles related to transmission of infection by gastrointestinal endoscopy or bronchoscopy; 265 articles were reviewed in detail. Two hundred and eighty-one infections were transmitted by gastrointestinal endoscopy, and 96 were transmitted by gastrointestinal endoscopy, spectrum of these infections ranged from asymptomatic colonization to death. Salmonella species and Pseudomonas aeruginosa were repeatedly identified as the causative agents of infections transmitted by gastrointestinal endoscopy, and Mycobacterium tuberculosis, atypical mycobacteria, and P. aeruginosa were the most common causes of infections transmitted by bronchoscopy. One case of hepatitis B virus transmission via gastrointestinal endoscopy was documented. Major reasons for transmission were improper cleaning and disinfection procedures; the contamination of endoscopes by automatic washers; and an inability to decontaminate endoscopes, despite the use of standard disinfection techniques, because of their complex channel and valve systems. The most common agents of infection transmitted by endoscopy are Salmonella, Pseudomonas, and Mycobacterium species. To prevent endoscopic transmission of infections, recommended disinfection guidelines must be followed, the effectiveness of automatic washers must be carefully monitored, and improvements in endoscope design are needed to facilitate effective cleaning and disinfection.
