Summary
Across 774 samples from two New York hospitals, NaDCC-treated high-touch surfaces had the lowest colony counts (14 colony-forming units). Electrolyzed water had higher counts (37 colony-forming units, P < .001 against NaDCC) and more samples with growth.
Key points
- Surfaces disinfected with NaDCC had the lowest mean colony count (14 colony-forming units), against 18 with peracetic acid and hydrogen peroxide (not a significant difference) and 37 with electrolyzed water.
- Peracetic acid with hydrogen peroxide and electrolyzed water both had more samples with any bacterial growth than NaDCC.
- Electrolyzed water and NaDCC were applied with electrostatic sprayers, following hospital protocol.
- All three products are sporicidal disinfectants used against C. difficile and Candida auris.
- Design: 774 samples from 5 high-touch surfaces in randomly selected rooms at 2 New York City hospitals over 18 months, cleaned by housekeeping staff.
