Quantitative respirator fit tests for P2/N95 in Australian general practice

Over the past two years, the COVID-19 pandemic has forced general practice to rapidly modify practice. A key change in service delivery is the requirement to wear P2/N95 masks in potential high-risk settings.1 In many hospitals, condensation nuclei counter (CNC)-based quantitative fit testing has been recommended as the gold standard by US National Institutes of Labor and UK legislation.2 Quantitative fit testing of healthcare workers is also emerging as the standard of practice in the Australian public hospital system.3 To date, there is limited information on the feasibility of establishing a quantitative fit testing program in primary care settings. Here, the authors report the results of a pilot trial of quantitative fit testing in metropolitan general practice and how fit test failures were managed.
