New duodenoscope surveillance culturing protocol

Written by 

Duodenoscopes are lifesaving devices. These flexible, lighted tubes are used in many clinical procedures, such as draining fluids from blocked pancreatic and biliary ducts, a procedure performed around 500,000 times each year in the United States. However, the same flexible design that allows their deft movement during patient procedures also results in a difficult cleaning process.

Contaminated duodenoscopes have been the source of patient outbreaks, including outbreaks of carbapenemase-resistent Enterobacteriaceae (CRE), which can cause dangerous and hard-to-treat infections in patients. A collaboration between ASM, the Food and Drug Administration (FDA), and the Centers for Disease Control and Prevention (CDC) has produced a new protocol for culturing duodenoscopes that aims to halt this mode of transmission by better identifying contaminated scopes.

Protocol: Duodenoscope Surveillance Sampling & Culturing

The new protocol replaces an Interim Duodenoscope Surveillance Protocol in place since 2015 with one that has been validated to extract between 65 to 100% of bacterial cells placed on the device. The protocol is designed to be used for surveillance purposes, and not the more extensive culturing that would occur if a duodenoscope were suspected of transmitting an infection. The surveillance culturing, in addition to meticulous cleaning as part of strict adherence to the manufacturer’s reprocessing instructions, is meant to reduce the risk of infection transmission associated with these devices. 

Do you want to learn more about the new protocol, how to implement it, and how it may affect culture growth results? The FDA is hosting a webinar on March 22, 2018, from 1:00-2:30pm EST. Independent experts and representatives from the CDC and ASM will be available to helpl answer any questions you may have. No registration is required for participation.
