OBJECTIVES/HYPOTHESIS: Severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) is transmitted by droplet as well as airborne infection. Surgical patients are vulnerable to the infection during their hospital admission. Some surgical procedures are classified as aerosol generating (AGP). STUDY DESIGN: Retrospective observational study of four specialties associates with known AGP's during the 4 months of the first wave of UK COVID-19 epidermic to identify post-surgical cross-infection with SARSCoV-2 within 14 days of a procedure. METHODS: Retrospective observational study in a tertiary healthcare center of four specialties associates with known AGP's during the 4 months of the first wave of UK COVID-19 epidermic to identify post-surgical cross-infection with SARSCoV-2 within 14 days of a procedure. RESULTS: There were 3,410 procedures reported during this period. The overall cross-infection rate from tested patients was 1.3% (4 patients), that is, 0.11% of all operations over 4 months. Ear, nose, and throat carried slightly higher rate of infection (0.4%) than gastroenterology (0.08%). The mortality rate was 0.3% (one gastroenterology patient from 304 positive cases) compared to 0% if surgery performed after recovery from SARSCoV-2 and 37.5% when surgery was conducted during the incubation period of the disease. Routine preoperative rapid screening tests and self-isolation are crucial to avoid the risk of cross-infection. Patients with underlying malignancy or receiving chemotherapy were more prone to pulmonary complications and mortality. CONCLUSION: The risk of SARS-COV-2 cross-infection after surgical procedure is very low. Preoperative screening and self-isolation together with personal protective measures should be in place to minimize the cross-infection. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2749-E2754, 2021.
