Approximately 35,000 children are born in the US each year with Congenital Heart Disease (CHD). Surgical timing for many of these conditions is elective, and the distribution of surgical cases, therefore, varies with time of year. The hypothesis of this project is that time of the year for surgery is associated with mortality, length of hospital stay (LOS), and total hospital costs. A retrospective, cohort study was performed, using the Pediatric Health Information Systems (PHIS) Database to investigate these relationships.
