Abstract:
A 2-question survey was performed at the 2022 Annual Meeting of the Association of Professionals in Infection Control (APIC) regarding whole-room ultraviolet C (UVC) disinfection devices. Ninety-six questionnaires were completed. About 82.3% indicated FDA regulation of UVC devices would help them, 5.2% responded they would not, and 12.5% were neutral. About 84.4% ranked thoroughness of disinfection as the most important attribute of a whole-room UVC device. And 13.5% indicated ease of use and time required as most important.

Cleaning, Sterilization, and Disinfection
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...

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
