SAN DIEGO – Less than a third of hospitals reprocessed duodenoscopes adequately to prevent potential transmission of carbapenem-resistant Enterobacteriaceae (CRE) and other pathogens, investigators reported at an annual scientific meeting on infectious diseases.
Moreover, only a third of facilities had conducted active surveillance for multidrug-resistant infections related to use of their duodenoscopes in the past year, reported Susan Beekmann of the Emerging Infections Network of the Infectious Diseases Society of America. “These findings suggest that endemic bacterial transmission associated with duodenoscopy may occur and may go unrecognized,” said Ms. Beekmann, program coordinator for EIN at the University of Iowa Carver College of Medicine in Iowa City.
Duodenoscopes, which are used in endoscopic retrograde cholangiopancreatography (ERCP), became a hot topic earlier this year after causing outbreaks of fatal CRE infections in Los Angeles County. The Food and Drug Administration has acknowledged that the “complex design of the devices makes it difficult to remove contaminants compared to other types of endoscopes,” and both the CDC and the FDA have recommended specific reprocessing and surveillance steps to reduce the chances that the scopes transmit serious infections.
To understand how hospitals were actually reprocessing and culturing the scopes at the time CDC released its guidance, Ms. Beekmann and her colleagues electronically surveyed 740 hospital epidemiologists through IDSA-EIN. They received responses from 378 physicians (52%), of which half said their facilities used duodenoscopes, Ms. Beekmann reported at the combined annual meetings of the Infectious Diseases Society of America, the Society for Healthcare Epidemiology of America, the HIV Medicine Association, and the Pediatric Infectious Diseases Society.
Only 55 (29%) of these respondents said their facilities reprocessed duodenoscopes to an extent that the IDSA researchers defined as adequate – that is, manual reprocessing with high-level disinfection, either alone or in combination with other options, Ms. Beekmann said. Furthermore, only a third of facilities had cultured their duodenoscopes or done any other surveillance for bacterial transmission after duodenoscopy in the past year, even though most said they reviewed their reprocessing policies and procedures more often than once a year.
Respondents also described widely varying methodologies for sampling and culturing, Ms. Beekmann said. “Although we did not ask about them, ten respondents mentioned ATP bioluminescence assays,” she added. Based on the findings, better reprocessing technologies and consistent, real-time strategies to monitor the effectiveness of scope reprocessing are “urgent patient safety needs,” she and her colleagues concluded.
Ms. Beekmann and her associates reported no relevant financial disclosures.
