BACKGROUND: The coronavirus disease SARS-CoV-2 (COVID-19) has swiftly spread throughout the globe, greatly influencing all aspects of life. As in previous pandemics, concerns for limited resources and a sustainable medical workforce have been on the forefront of infrastructure modifications. Consequently, surgical specialties have needed to consider each surgical case for necessity and safety during the COVID-19 outbreak. At our institution, availability of SARS-CoV-2 assay has allowed preoperative testing of asymptomatic surgical patients. AIM/ OBJECTIVE: To better define the prevalence of asymptomatic carriers in a surgical population and to better understand the impact of testing on our personal protective equipment (PPE) supply. METHODS: We began routine, preoperative testing for all asymptomatic patients coming to our academic medical centre on 30 March 2020. Scheduled surgeries were deemed urgent by the surgeon with a review for appropriateness by a novel surgical committee. A retrospective patient chart review was performed. Emergency surgeries were excluded. Asymptomatic patients with positive test results had their surgeries rescheduled at the discretion of the surgeon and patient. Patients who tested negative underwent surgery with staff using standard PPE. RESULTS: Eighty-four asymptomatic surgical patients were tested preoperatively with three (3.6%) testing positive for SARS-CoV-2. Preoperative testing saved 498 N95 respirators over this time period. DISCUSSION: This is the first report of routine COVID-19 preoperative testing in an asymptomatic surgical population. Within this population, there is a 3.6% rate of asymptomatic SARS-CoV-2 carriers. Through this practice, personnel exposure can be minimised and access to PPE can be preserved.
