Breaking the chain of transmission within a tertiary health service: An approach to contact tracing during the COVID-19 pandemic

Background: Tertiary referral health service. Intervention(s): An approach to hospital based contact tracing is described along with tools employed to streamline the process and including the development of an outbreak management team (OMT) for each contact trace. Results: Forty-one OMTs occurred, involving 23 HCW and 18 patient index cases. The total furloughed HCWs arising from these contact traces was 383, with individual contact traces furloughing a mean (range) of 10 (0-80) HCWs. Importantly, 15 furloughed HCWs subsequently became COVID19 positive during their 14-day isolation period, showing the importance of the contact tracing process and the ability to remove workers from the workplace before they become infectious. Conclusions: A standardised, streamlined contact tracing procedure in healthcare settings ensures any impacts of COVID-19 positive cases are consistently managed. This response framework may be of use to other health services and help reduce the transmission of COVID-19 in the workplace. (C) 2020 Australasian College for Infection Prevention and Control.
