Abstract
Evidence-based protocols identifying COVID-19 cases in pediatric preoperative settings are lacking. With COVID-19 positioned to remain a threat to children, this study examines effectiveness of preoperative COVID-19 symptom screening in pediatric patients. METHODS: This retrospective cohort study included hospital billing/medical record queries of (1) procedures performed under conscious sedation/general anesthesia and (2) laboratory-confirmed COVID-19 (+) cases from April 6, 2020, to June 15, 2020. Descriptive analyses were performed for demographic, procedural, symptom, and COVID-19 test result data obtained from medical records. Bivariate analyses examined associations between SARS-CoV-2 test results and symptom, demographic, and procedural data. RESULTS: Among 2900 surgical cases, median (interquartile range) age was 8.1 (12.8) years. The majority were male (n = 1609, 55.5%), white (n = 1614, 55.7%), and not Hispanic/Latino (n = 1658, 57.2%). Additionally, 85.4% (n = 2412) of cases were non-emergent. Fifteen COVID-19 (+) cases were identified, for a 0.5% positivity rate. COVID-19 positivity was not associated with sex, American Society of Anesthesiologists physical status, or preoperative symptom status. Notably, 92.9% (n = 13) of COVID-19 (+) cases were asymptomatic. COVID-19 (+) patients were significantly older (15.6 years) than COVID-19 (-) patients (8.0 years). Patients who were not white, were Hispanic/Latino, or had a relatively lower economic status, were more likely to test positive. CONCLUSIONS: Preoperative symptom screenings insufficiently identified COVID-19 (+) patients. During outbreaks, testing protocols should be implemented to identify COVID-19 (+) patients. Future research should examine if observations are similar for other variants, and how health disparities associate with COVID-19.
