Perioperative COVID-19 Screening at a Tertiary Ophthalmic Institution

Abstract

Purpose: To characterize the rate of COVID-19 positivity during presurgical screening and the surgical outcomes of ophthalmic patients who were positive for COVID-19 and to report the overall cost. Methods: This retrospective study included patients 18 years or older who had ophthalmic surgical procedures at a tertiary institution between May 11, 2020, and December 31, 2020. Patients without a valid presurgical COVID-19 test within 3 days before their scheduled procedure, who had incomplete or mislabeled visits, or who had incomplete or missing data in their file were excluded. COVID-19 screening was completed using a polymerase chain reaction (PCR) kit. Results: Of the 3585 patients who met the inclusion criteria, 2044 (57.02%) were women; the mean age was 68.2 years ± 12.8 (SD). Thirteen asymptomatic patients (0.36%) tested positive for COVID-19 via PCR screening. Three patients had a known positive COVID-19 infection within the 90 days before surgery; thus, 10 patients (0.28%) were found to have asymptomatic naïve COVID-19 infection via PCR testing. Testing was associated with a total charge of US $800 000. Five of the 13 patients (38.46%) who tested positive for COVID-19 experienced a delay in their surgery; the mean delay was 17.23 ± 22.97 days. Conclusions: Asymptomatic ophthalmic surgical patients had a low positivity rate with a limited impact on surgery scheduling at a significant cost. Further studies would be valuable in evaluating a targeted presurgical screening population as opposed to universal testing.
