Background:
Neonatal Intensive Care Units utilize incubators to sustain core temperatures associated with transepidermal water loss. High relative humidity in incubators provides an environment for fungi to grow. In August 2022, mold was identified growing in 11 (85%) Neonatal Intensive Care Unit incubators.
Methods:
A team assembled to address mold in incubators. The environment was addressed as a possible source of contamination by consulting an environmental specialist. The air handler, ducts, and environment were terminally cleaned. Specimens were collected from the contaminated incubators and the manufacturer reviewed cleaning practices. Experimental trials were conducted using the incubators to replicate mold growth after interventions.
Results:
The environmental consultant approved when the space could be reoccupied. Incubators introduced to the clean environment did not grow mold. Various fungi or yeast were identified in the contaminated incubators. Opportunities to improve cleaning and replacement of parts were identified by the manufacturer. September 2022 to February 2023, 7 experimental trials were completed after cleaning the incubators. Four (36%) of the 11 contaminated incubators were placed back in use due to no fungal growth. No patient illnesses occurred.
Conclusions:
The interventions implemented stopped ongoing contamination of incubators and use of previously contaminated incubators.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
