Abstract

Background: Candida auris (C. auris) is an emerging fungal pathogen that poses a serious health threat. This multidrug-resistant fungus has been especially prevalent in southeast Michigan, largely due to interfacility transfer. Active C. auris surveillance is recommended by governing agencies. Methods: In response, the hospital developed isolation and screening protocols for high-risk patients to mitigate risks and prevent further spread. A proactive screening program for C. auris was established for high-risk patients presenting to the hospital, complemented by a partnership with the State Health Department to identify known positive patients. In response to multiple C. auris cases over a 15-month period, 12 point-prevalence studies (PPS) were conducted as part of exposure investigations, screening more than 500 patients. As a result, six patient care units along with ancillary areas visited by affected patients underwent full terminal cleaning. Results: The investigation and review of PPS results suggested possible facility transmission of the pathogen, prompting a thorough evaluation of current cleaning and disinfection practices. Because environmental hygiene is a critical factor in reducing the spread of this organism, the products and technologies used for daily room cleaning were reassessed. This review revealed that the cleaning agents in use did not have kill claims for C. auris, and the ultraviolet light disinfection system was not operating on a cycle validated to inactivate C. auris. Conclusions: This prompted the Infection Prevention team to immediately advocate for new cleaning products registered on the EPA’s List P, which includes agents with proven efficacy against C. auris. Two disinfection products were rapidly trialed, and one was ultimately selected for implementation. This work underscores the importance of Infection Preventionists in advocating for effective cleaning products and being actively involved in the product selection process across the hospital and health system.
