[Hygiene in endoscopy in clinic and practice 2013 in comparison with 2003--structure and process quality]. / Struktur- und Prozessqualität bei der Aufbereitung flexibler Endoskope in Klinik und Praxis in Frankfurt am Main--2013 im Vergleich zu 2003.

ABSTRACT

BACKGROUND: Endoscopy is an important part of modern medical diagnostics and therapy. The invasive procedures are however associated with a risk to transmit infections. Against this background the KRINKO has published the "Hygienic requirements for the reprocessing of flexible endoscopes and endoscopic accessories" in 2002 and has updated these recommendations in 2012. In 2003 and 2013 all gastroenterological facilities in Frankfurt am Main using flexible endoscopes were monitored for compliance with the recommendations. METHODS: The inspections were performed after prior notice by a staff member of the health authority using a checklist which had been developed on the basis of the current KRINKO recommendations. RESULTS: In both years all institutions performing endoscopic procedures were visited 2003 15 hospitals and 23 practices; 2013 14 clinics and 10 practices. In 2013 (data for 2003 in brackets) 100 % (93 %) of the hospitals and 60 % (22 %) of practices reprocessed their endoscopes by automated methods. The appropriate reprocessing and filling of water bottles for rinsing the scope channels with sterile water and the sterilisation of accessories were satisfactorily performed in 2003 and 2013 by all hospitals. However in 2013 only 90 % (2003 74 %) of the practices correctly reprocessed water bottles and 80 % (52 %) used sterile water for filling the bottle. In 2013 100 % (2003 57 %) of the practices correctly sterilised accessory instruments, while 2 practices used disposable, i. e., single-use materials. In 2013 all institutions performed microbiological tests according to KRINKO recommendations, while in 2003 all hospitals but only 43 % of the practices could present such tests. DISCUSSION: While the gastroenterological departments of Frankfurt hospitals already complied with the KRINKO recommendations in 2003, the inspection of several practices in 2003 had revealed considerable shortcomings in the implementation of these recommendations. Subsequently the practices have improved their hygiene management.
