“…At Site B, de novo introduction of EHMRs involved multiple training modalities, including videos and the visible presence of the perioperative department, who led the decontamination effort. 17 At Site A, HCP may have felt reluctant to use a decontaminated respirator that had been used by another person, even though a rigorous C&D process existed.…”

“…This process included detergent‐based cleaning and high‐level disinfection of EHMRs between users, except in the emergency department (ED), where each HCP was provided an individually issued, personal EHMR 11 . Site B also included a centralized C&D program sponsored by the CSP department, although use of this program was optional at the time of survey 17 . Site B had converted from a shared EHMR program to each HCP being provided their own EHMR.…”

“…11 Site B centrally cleaned and disinfected EHMRs using a quaternary ammonium compound-based product (MSA Confidence Plus ® 2 Germicidal Cleaner). 17 At the time of survey, local policies instructed HCP to doff the respirator after each patient care encounter. While guidance was available, extended use (wherein respirators are worn continuously and between multiple patients) was uncommon.…”

“…Relying on these published protocols and manufacturer IFU, two US medical organizations implemented respiratory protection programs (RPP) including EHMRs. Both organizations incorporated centralized standardized C&D through their Central Sterile Processing (CSP) departments but also relied on HCP to wipe the EHMR surfaces with disinfectant wipes after each respirator doffing 11,12,17 . Such protocols promoted safe infection control practices but still relied on HCP behavior to maintain these strategies.…”

BackgroundDisposable N95 respirator shortages during the COVID‐19 and 2009 H1N1 influenza pandemics highlighted the need for reusable alternatives, such as elastomeric half‐mask respirators (EHMRs). Two US medical organizations deployed reusable EHMRs during the COVID‐19 response. In addition to wipe‐based disinfection following patient care episodes expected per local policies at both organizations, postshift centralized cleaning and disinfection (C&D) was expected at one site (A), permitting shared‐pool EHMR use, and optional at the other (Site B), where EHMRs were issued to individuals. Using a survey, we evaluated disinfection practices reported by EHMR users and predictors of disinfection behaviors and perceptions.MethodsSurveys assessed EHMR disinfection practices, occupational characteristics, EHMR use frequency, training, and individual‐issue versus shared‐pool EHMR use.ResultsOf 1080 EHMR users completing the survey, 76% reported that they disinfect the EHMR after each patient encounter, which was the expected practice at both sites. Increasing EHMR use, recall of disinfection training, and work in intensive care or emergency settings significantly influenced higher reporting of this practice. 36% of respondents reported using centralized C&D, although reporting was higher at the site (A) where this was expected (53%). Confidence in cleanliness of the EHMR following centralized C&D was not influenced by individual versus shared‐pool EHMR issue.ConclusionsMost EHMR users reported adherence with expected post‐care individual‐based disinfection of EHMRs but did not necessarily use standardized, centralized C&D. Future efforts to limit reliance on behavior related to respirator disinfection may improve EHMR implementation in healthcare to avert dependence on single‐use, disposable N95 respirators.
