Incidence of Fit Test Failure During N95 Respirator Reuse and Extended Use.

ABSTRACT:

Importance

The COVID-19 pandemic resulted in a widespread acute shortage of N95 respirators, prompting the Centers for Disease Control and Prevention to develop guidelines for extended use and limited reuse of N95s for health care workers (HCWs). While HCWs followed these guidelines to conserve N95s, evidence from clinical settings regarding the safety of reuse and extended use is limited.

Objective

To measure the incidence of fit test failure during N95 reuse and compare the incidence between N95 types.

Design, setting, and participants

This prospective cohort study, conducted from April 2, 2021, to July 15, 2022, at 6 US emergency departments (EDs), included HCWs who practiced N95 reuse for more than half of their clinical shift. Those who were unwilling to wear an
