Worse Hospital Outcomes for Children and Adults with COVID-19 and Congenital Heart Disease.

The aim of the current study is to investigate hospitalization outcomes of COVID-19 positive children and adults with moderate or severe congenital heart disease to children and adults without congenital heart disease. Retrospective review using the Vizient Clinical Data Base for admissions of patients with an ICD-10 code for COVID-19 from April 2020 to March 2021. Admissions with COVID-19 and with and without moderate or severe congenital heart disease (CHD) were stratified into pediatric (< 18 years) and adult (≥ 18 years) and hospital outcomes were compared. There were 9478 pediatric COVID-19 admissions, 160 (1.7%) with CHD, and 658,230 adult COVID-19 admissions, 389 (0.06%) with CHD. Pediatric admissions with COVID-19 and CHD were younger (1 vs 11 years), had longer length of stay (22 vs 6 days), higher complication rates (6.9 vs 1.1%), higher mortality rates (3.8, 0.8%), and higher costs ($54,619 vs 10,731; p < 0.001 for all). Adult admissions with COVID-19 and CHD were younger (53 vs 64 years, p < 0.001), had longer length of stay (12 vs 9 days, p < 0.001), higher complication rates (8 vs 4.8%, p = 0.003), and higher costs ($23,551 vs 13,311, p < 0.001). This appears to be the first study to report the increased hospital morbidities and costs for patients with CHD affected by COVID-19. Our hope is that these findings will help counsel patients moving forward during the pandemic.
