{Abstract}: BACKGROUND: Verifying the fit of disposable N95/P2 half-face respirators is critical. There are currently no objective ways to evaluate the implementation when used. Previously, we showed that only 26% of healthcare workers achieve appropriate fit at the point of use.
METHODS: 657 quantitative fit tests were conducted on 166 subjects, using four different respirator styles. Randomization was performed; controls employing standard 'fit-check' and intervention using a custom built infra-red video kiosk. Primary outcome was passing rates of quantitative fit, with secondary outcomes of respirator type, gender, race, and previous experience.
RESULTS: Intervention demonstrated significantly higher pass rate (50.6%) compared to controls (30.8%). The odds of passing with IR Kiosk compared to control was 2.3 (OR 2.3 95%CI 1.8 to 2.9, p<0.001). Duckbill style improved the greatest (OR 4.1 95%CI 2.1 to 7.9, p<0.001), and Tri-fold also showing substantial benefit (OR 2.66 95%CI 1.4 to 5.2, p<0.001). Gender and race did not influence the outcomes when using the kiosk, nor did previous experience.
CONCLUSIONS: A custom point of use kiosk improved the odds of achieving a satisfactory fit of common respirator styles, independent of participant demographics. These findings open the door to addressing a critical gap in respiratory protection programs by providing individual assessment and interventions that improve worker safety at the time of highest risk.
