Costing of an Australian general practice COVID-19 drive-through testing and respiratory clinic

Background: Responding to the COVID-19 pandemic requires safe and efficient testing on a large scale over a prolonged period. Outpatient testing facilities can clinically assess and test symptomatic individuals and test asymptomatic contacts. This study identified the resources required to establish and maintain an Australian general practitioner (GP) led testing facility that combined a respiratory clinic for clinical assessment and testing with a drive-through testing facility. Methods: Data were taken from clinic administrative records to identify the number of patients tested over the period April-June 2020. An independent auditor’s report identified the resources used in establishing, running, and staffing both clinics for the same period. Analyses were performed using the minimum and maximum daily throughput to understand the effect of demand on price per sample collected. Results: The respiratory clinic tested an average of 19 patients per day, at an estimated cost of $340.04 AUD. This varied to $687.99 AUD during the lowest demand scenario, and $281.04 AUD during the high demand scenario. The drive-through clinic tested an average of 47 patients per day, at an estimated cost of $153.57 AUD. This varied to $279.51 AUD during the lowest demand scenario, and $99.92 AUD during the high demand scenario. Conclusion: This study provides insight into the cost of testing at a drive through and respiratory clinic in Australia. The evidence highlights importance of considering variation in demand and the impact on efficiency, particularly where resource use is fixed in the short term.
