APIC: Manual Cleaning of Endoscopes Ineffective

Monday, June 10, 2013 (Last Updated: 06/11/2013)

MONDAY, June 10 (HealthDay News) -- Manual cleaning of endoscopes is not effective, with the highest failure rates for duodenoscopes and gastroscopes compared with colonoscopes, according to a study presented at the annual conference of the Association for Professionals in Infection Control and Epidemiology, held from June 8 to 10 in Fort Lauderdale, Fla.

Marco Bommarito, Ph.D., from the 3M Infection Prevention Division in St. Paul, Minn., and colleagues used an adenosine triphosphate bioluminescent assay to examine the cleanliness of 275 flexible duodenoscopes, gastroscopes, and colonoscopes after the manual cleaning step of the decontamination and disinfection process.

The researchers found that the failure rate was 30 percent for duodenoscopes, 24 percent for gastroscopes, and 3 percent for colonoscopes. The threshold for failure was set at 200 relative light units based on previously published clinical data, the authors note.

"The cleaning protocols for flexible endoscopes need improvement, such as guidelines tailored to the type of scope or identifying if there is a critical step missing in the manual cleaning process, and documented quality control measures," Bommarito said in a statement. "These types of improvements could have a positive impact on patient safety."

The authors are employees of 3M.
