What We Can Learn from Candida auris Outbreak
By Rosie Lyles, MD, MHA, MSc, FACA | June 26, 2018
In May, I attended the Centers for Disease Control and Prevention’s advisory committee for infection control. From there, along with weekly monitoring, I am now hyper aware of the next emerging deadly pathogen: Candida auris. This fungus is considered to be a serious global threat because it’s multidrug-resistant, can only be identified in specialized labs and is already causing outbreaks in healthcare settings.
But what I took away from the presentation could be applied to many of the outbreaks healthcare systems have tackled and will continue to deal with when it comes to infection prevention.¹
Review environmental disinfection
In the hospital, the obvious places where C. auris cultures existed include the bed rails, sheets and chairs. Cultures were also found on shoes, the temperature probe and even the hand sanitizer dispenser. Bleach germicidal cleansers, hydrogen peroxide and cleansers with 10 percent sodium hypochlorite all performed well in killing C. auris on surfaces. The CDC even recommended preemptively disinfecting in common areas as all long-term care facilities with ventilated patients.
Pull together your PPE
As we go through our daily responsibilities, it can feel like we’re simply going through the motions and we often forget the importance of personal protective equipment. Gowns, gloves and masks can prevent or even stop cross contamination. We shouldn’t wait for outbreaks to implement PPE protocols. Hospitals and long-term care facilities should think ahead and be prepared.
Another point the CDC made was about decolonization. If you decolonize a patient with C. auris with an antiseptic such as chlorhexidine gluconate (CHG), you actually stop cross transmission from the patient to the environment, as well as healthcare workers.² Clinicians need to remember proper antibiotic stewardship and consider using topical antiseptics to reduce body surface bacteria to prevent carriage and infections.
During the Ebola outbreak, there was no stronger realization, based on the fear healthcare professionals felt, for the need to always have reserved rooms for infected patients. Same goes for C. auris patients based on recommendations from the CDC. Colonization is said to happen for months prior to the organism being detected increasing transmission.
Vigilant infection prevention practices
C. auris may be the next emerging outbreak that hospitals and nursing homes are faced with, but the proper infection prevention practices should carry through from previous infectious events. Remain vigilant. That awareness helps any facility stay prepared.
Are you implementing solutions that are grounded in best practice to help support your infection prevention plans?
