Occupationally acquired COVID-19 is a hazard for healthcare workers (HCWs). In four hospitals of the Metro North Hospitals and Health Service in Queensland, Australia, we invited HCWs to report the nature of any anaesthesia interactions with COVID-19-positive and COVID-19-suspect patients. This was to assist workforce planning in future pandemics. Data collection consisted of three phases; 1) participating HCWs recorded details of episodes of care (EOCs) with COVID-19-positive or COVID-19-suspect patients; 2) these HCWs were invited to complete a follow-up survey about their own health status regarding COVID-19 infections; 3) electronic health records were used to assess patient demographics, infectious status and outcomes. Between 21 March 2020 and 17 May 2022, 63 anaesthesia HCWs reported 90 EOCs with 67 unique patients. The median (interquartile range (IQR)) age of the HCWs was 40.5 years (34-46); 55% (34/62) were male, 62% (39/63) were consultants and 21% (13/63) were registrars. The median (IQR) age of patients was 39 (28-63) years. Personal protective equipment (PPE) was deemed to be appropriate by the HCWs in (86/88) 98% of the EOCs. Twenty-four HCWs (38%) responded to a follow-up survey. Of 12 HCWs who subsequently tested positive to COVID-19, only four had cared for a COVID-19-positive patient in the two weeks prior to their diagnosis. Most responding HCWs perceived they contracted COVID-19 in the community, experiencing mild illness. We found relatively low COVID-19 case numbers, high PPE use and low transmission of COVID-19 within the hospital setting.
