Abstract

Coarctation of the aorta is a relatively common congenital heart disease occurring in 0.4-0.6 per 1000 live births with a low mortality rate. This is a retrospective study, with data abstracted from the Pediatric Health Information System database (PHIS). The study sample included pediatric patients less than or equal to 3 months of age discharged from a PHIS participating hospital between January 1, 2004 and December 31, 2018 who underwent surgical repair of isolated COA. The primary outcome for the study was post-operative hospital length of stay (PH-LOS), and the secondary outcome was in-hospital mortality. Patient demographics, comorbidities, procedures, and outcomes were assessed for statistical differences between eras. A total of 5354 patients were included in the study. The study highlights an increasing trend in PH-LOS and NICU hospital length of stay (NICU-LOS) across the investigated eras. Prematurity (before 37 weeks gestation) was an independent risk factor associated with both longer post-operative length of the stay and higher mortality. In addition, congenital anomalies, respiratory and abdominal surgeries have a significant impact on the post-operative hospital stay. In conclusion, this study is the largest published systematic assessment of PH-LOS in patients with isolated COA repair during infancy to date and identifies independent risk factors of increased PH-LOS.
