Risk Factors for Increased Hospital Resource Utilization and In-Hospital Mortality in Adults With Single Ventricle Congenital Heart Disease

Most patients with single ventricle congenital heart disease are now expected to survive to adulthood. Co-morbid medical conditions (CMCs) are common. We sought to identify risk factors for increased hospital resource utilization and in-hospital mortality in adults with single ventricle. We analyzed data from the 2001 to 2011 Nationwide Inpatient Sample database in patients aged ≥18 years admitted to nonteaching general hospitals (NTGHs), TGHs, and pediatric hospitals (PHs) with either hypoplastic left heart syndrome, tricuspid atresia or common ventricle. National estimates of hospitalizations were calculated. Elixhauser CMCs were identified. Length of stay (LOS), total hospital costs, and effect of CMCs were determined. Age was greater in NTGH (41.5 ± 1.3 years) than in TGH (32.8 ± 0.5) and PH (25.0 ± 0.6; p
