Barcode scanning is an effective, albeit more expensive, way to
track storage interval, but the technology is still prone to human error
— a tech must scan the scope when hanging it in a cabinet to create a
digital record of the storage starting date. If you want to automate the
entire process, some newer storage cabinets come with integrated
RFID sensors that scan and timestamp RFID-enabled endoscopes.
We based our 7-day cutoff on the Society of Gastroenterology Nurses
and Associates' recommendation and the oft-cited 2015 review of endo-
scope storage time studies (osmag.net/EZcb9D) that suggests you don't
need to reprocess an "effectively reprocessed and appropriately stored"
scope if you use it within a week.
The review showed extremely low bioburden contamination rates
and that pathogens rarely formed in endoscope channels within a
week of disinfection, says study co-author Marilee Schmelzer, PhD,
RN, CGRN, who recently retired from her teaching position at the
University of Texas at Arlington.
"But," says Dr. Schmelzer, pausing for emphasis, "that's only if the
scopes are properly disinfected and stored correctly."
Easier said than done. Conduct occasional spot checks of microbial
growth in stored scope channels to determine if your safe storage
timeframe is adequate, says Dr. Schmelzer. However, ATP and DNA
testing are too expensive and too time-consuming for routine use, she
says.
For now, focus on setting your own storage interval. Assign a quality
control team to review current literature and establish a storage time
limit that makes sense for your scope inventory and case load, says
study co-author Glenda Daniels, PhD, MS, BSN, an associate profes-
sor of nursing at Texas Christian University in Fort Worth.
"Once you establish the policy, make sure it's strictly enforced," says
Dr. Daniels. "You can get in trouble if a patient is infected and your
