OBJECTIVES/GOALS: Patients with nsCL/P are prone to infections due to their open like wound cleft and immune system susceptibility. COVID-19 affected nsCL/P patients access to care and treatment delays. This study will determine COVID-19 infection risk between children with nsCL/P compared to those unaffected. METHODS/STUDY POPULATION: Retrospective cohort of children 5 years old and under with nsCL/P (exposed group) and children without nsCL/P (unaffected group); matched by age and gender. Participants will be selected from ongoing case-control study (n=500), School of Dental Medicine, and Pediatric University Hospital. Power analysis will calculate minimum sample size (power=0.80 alpha=0.05). Exclusion criteria: syndromic clefts, patients without diagnosis information and with history of co-morbidity. Other bacterial and viral infections present at the time of COVID-19 diagnosis, sex, age, geographic location, COVID-19 vaccination status and others will be considered as possible cofounders. Descriptive statistics, Chi-square, Odds Ratios at 95% confidence intervals and multiple logistic regression will be estimated. RESULTS/ANTICIPATED RESULTS: We hypothesize that we will identify an increased risk of COVID-19 infection in children with nsCL/P than in those unaffected or children without nsCL/P. Children with nsCL/P will also have an increased risk of symptoms and complications of COVID-19 infection than those unaffected. DISCUSSION/SIGNIFICANCE: Knowing the increased risk of COVID-19 infection in children with nsCL/P will aid to prioritize treatment. If a higher risk of COVID-19 infection is found, it will generate a need to modify elective surgery status to semi-elective; minimizing delayed treatments, unnecessary hospitalizations, complications and increased cost of treatment.
