Endoscopy’s Dirty Little Secret

Endoscopy’s Dirty Little Secret


Last week, AAMI published a listing of the Top 10 Technology Threats of 2018 . As one might expect cybersecurity took the top spot, but hazard number two was endoscope reprocessing.

Confronted with this news, one might logically assume that reprocessing departments are redoubling their efforts to follow established procedures and reduce this threat. While that is very likely the case in most places, the fact that endoscopy reprocessing has been a high ranking hazard on eight of the last 10 previous editions suggests that maybe part of the problem may be with the established procedures themselves.

According to this article on the ECRI website, there are seven steps involved in reprocessing endoscopes, including: “precleaning in the patient procedure room, transport to a decontamination or reprocessing room, manual cleaning, a disinfection cycle (often with an automated endoscope reprocessor), alcohol rinsing, drying, and storage.”

The AAMI list of threats focused on two main areas of concern: insufficient removal of biological debris and other foreign materials during the precleaning stage and moisture trapped in instrument channels during storage.

Regarding storage, Case Medical has addressed the issue of dry vs. wet loads in many blog posts including this one. Regarding precleaning, Case Medical has identified a common precleaning procedure that may be contributing to the recurring threat endoscopy reprocessing poses in the AAMI ranking.

Currently, one of the most widely used precleaning products is a packet containing a sponge soaking in a detergent solution. Standard precleaning protocol is to wipe the endoscope with the sponge, three times from top to bottom, then flush the instrument with the liquid remaining in the bag. The problem is, after the first pass, the sponge is contaminated with all of the debris and fluids which are effectively reapplied to the instrument on passes two and three.

To address this situation, Case Medical has innovated a new precleaning packet for endoscopes that replaces the sponge with, single use, non-woven disposable PentaWipes, premoistened with our EPA Safer Choice awarded PentaZyme, a multienzymatic cleaning solution. Each packet contains three PentaWipes in accordance with the protocol. Each case contains 12 packets as well as 12, 8oz bottles of PentaZyme for flushing.

By replacing three strokes with a dirty sponge with three single-use wipes, and providing a flushing solution in a separate sealed bottle, reprocessing departments can make significant progress toward removing endoscope reprocessing from AAMIs 2019 list of hazards.
