ABSTRACT
BACKGROUND:
Sporicidal disinfectants are necessary to control Clostridioides difficile and Candida auris. Novel application methods such as electrostatic sprayers may increase disinfection effectiveness. We employed a standardized protocol to assess 3 sporicidal disinfectants electrolyzed water (EW), sodium dichloroisocyanurate (NaDCC) and peracetic acid/hydrogen peroxide (PAA/H2O2).METHODS:
The study was conducted at 2 New York City hospitals (1,082 total beds) over an 18-month period. The 3 chemicals were applied by housekeeping personnel following the hospital protocol; the use of electrostatic sprayers was incorporated into EW and NaDCC. In randomly selected rooms, 5 surfaces were sampled for microbial colony counts after cleaning. Data analyses were performed using negative binomial logistic regression.RESULTS:
We collected 774 samples. NaDCC-disinfected surfaces had a lower mean colony count (14 colony forming units [CFU]) compared to PAA/H2O2 (18 CFU, P = .36) and EW (37 CFU, P < .001). PAA/H2O2 and EW had more samples with any growth (both P < .05) compared to NaDCC. NaDCC applied with wipes and an electrostatic sprayer had the lowest number of samples with no growth and <2.5 CFU/cm2 (difference not significant).CONCLUSIONS:
The use of NaDCC for surface disinfection resulted in the lowest bacterial colony counts on patient room high touch surfaces in our study.Palabras clave
