Environmental cleaning and disinfection of hospital rooms: A nationwide survey

Published:August 13, 2020DOI:https://doi.org/10.1016/j.ajic.2020.08.008

      Highlights

      • Hospitals appear to favor hypochlorite for disinfection of contact isolation rooms.
      • For noncontact isolation rooms, quaternary ammonium compounds were favored.
      • Sporicidal agents were rarely used in noncontact isolation rooms.
      • Floors were infrequently disinfected compared to other high-touch surfaces.
      • Many hospitals reported routine use of UV-C light room decontamination devices.

      Background

      As an important reservoir for hospital-acquired infections, environmental surfaces have long been targeted by interventions to improve cleaning and disinfection. Differences in disinfection practices across US hospitals, however, are still unclear.

      Methods

      We conducted a nationwide survey of environmental services (EVS) personnel in the United States regarding their environmental surface disinfection practices from January 2019 to June 2019. We developed and pilot tested the survey in conjunction with EVS specialists. Survey questions inquired about choices of disinfectants and cleaning equipment during daily and terminal disinfection of both contact isolation and non-contact isolation rooms. We contacted 273 EVS personnel by phone and email to participate in the survey.

      Results

      Fourty-seven EVS personnel representing different hospitals from 26 US states were included in the analysis. Hypochlorite (bleach) and quaternary ammonium compounds were the most frequently used disinfectants. Most respondents reported using microfiber-based cloths and mops to carry out disinfection. High-touch surfaces in contact isolation rooms were frequently disinfected using bleach (81%, n = 38); floors, however, were not disinfected as frequently in patient rooms. The vast majority of respondents reported use of sporicidal disinfectants for contact isolation rooms but not regular rooms.

      Conclusions

      While frequently used to disinfectant contact isolation rooms, sporicidal agents are rarely used to disinfect regular rooms. Patient room floors are inconsistently disinfected compared to high-touch surfaces.
