Contexte En tant que réservoir important d’infections nosocomiales, les surfaces environnementales ont longtemps été ciblées par des interventions visant à améliorer le nettoyage et la désinfection. Toutefois, les différences entre les pratiques de désinfection des hôpitaux américains ne sont toujours pas claires. Méthodes Nous avons mené une enquête nationale auprès du personnel des services environnementaux (EVS) aux États-Unis concernant leurs pratiques de désinfection des surfaces environnementales entre janvier 2019 et juin 2019. Nous avons développé et testé l’enquête en collaboration avec des spécialistes des services environnementaux. Les questions de l’enquête portaient sur le choix des désinfectants et des équipements de nettoyage lors de la désinfection quotidienne et terminale des salles d’isolement avec ou sans contact. Nous avons contacté 273 membres du personnel du SVE par téléphone et par e-mail pour participer à l’enquête.
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 US regarding their environmental surface disinfection practices from January 2019 – 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 47 EVS personnel representing different hospitals from 26 US states were included in the analysis. Hypochlorite (bleach) and quaternary ammonium compounds (QACs) 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.
