Use of Elastomeric Half-Mask Respirator in the Clinical Care Environment: Health Care Worker Perceptions

Elastomeric half-mask respirators (EHMR) reduce health care workers' exposure to airborne hazards including bioaerosols but have primarily been used in the industrial setting.

To assess health care workers' perceptions, attitudes, and experiences wearing EHMRs in a clinical environment.

Employees within a single health care system who wore the EHMR continuously during their shift completed an investigator developed survey. Descriptive statistics and thematic analysis were used.

Of the 8273 EHMR "fit-tested" eligible employees, 1478 met inclusion criteria and participated. Respondents reported that they felt well protected with the EHMR and confident in their care and maintenance of the EHMR. Although skin changes developed, they were primarily managed by adjusting the straps. Clarity of communication was a concern across all respondents and disciplines.

The EHMR was preferred over reusing the N95 although clarity in communication was challenging.
