tice guidelines for endoscope reprocessing re−
commend reprocessing endoscopes between
each case and proper storage following repro−
cessing after the last case of the list. There is lim−
ited empirical evidence to support the efficacy of
endoscope reprocessing prior to use in the first
case of the day; however, internationally, many
guidelines continue to recommend this practice.
The aim of this study is to estimate a safe shelf
life for flexible endoscopes in a high−turnover
Materials and methods: In a prospective obser−
vational study, all flexible endoscopes in active
service during the 3−week study period were mi−
crobiologically sampled prior to reprocessing be−
fore the first case of the day (n = 200). The main
outcome variables were culture status, organism
cultured, and shelf life.
Results: Among the total number of useable
samples (n = 194), the overall contamination rate
was 15.5 %, with a pathogenic contamination rate
of 0.5 %. Mean time between last case one day
and reprocessing before the first case on the
next day (that is, shelf life) was 37.62 h (SD
36.47). Median shelf life was 18.8 h (range 5.27±
165.35 h). The most frequently identified organ−
ism was coagulase−negative Staphylococcus, an
environmental nonpathogenic organism.
Conclusions: When processed according to es−
tablished guidelines, flexible endoscopes remain
free from pathogenic organisms between last
case and next day first case use. Significant re−
ductions in the expenditure of time and
resources on reprocessing endoscopes have the
potential to reduce the restraints experienced by
high−turnover endoscopy units and improve ser−
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
