PurposeGastroschisis is a severe congenital anomaly associated with a significant morbidity and mortality. There are limited temporal trend data on incidence, mortality, length of stay, and hospital cost of gastroschisis. Our aim was to study these temporal trends using the National Inpatient Sample (NIS).MethodsWe identified all neonatal admissions with a diagnosis of gastroschisis within the NIS from 2010 through 2014. We limited admission age to ≤ 28 days and excluded all those transferred to other hospitals. We estimated gastroschisis incidence, mortality, length of hospital stay, and cost of hospitalization. For continuous variables, trends were analyzed using survey regression. Cochrane–Armitage trend test was used to analyze trends for categorical variables. P < 0.05 was considered as significant.ResultsThe incidence of gastroschisis increased from 4.5 to 4.9/10,000 live births from 2010 through 2014 (P = 0.01). Overall mortality was 3.5%, median length of stay was 35 days (95% CI 26–55 days), and median cost of hospitalization was $75,859 (95% CI $50,231–$122,000). After adjusting for covariates, there was no statistically significant change in mortality (OR = 1.13; 95% CI 0.87–1.48), LOS (β = − 2.1 ± 3.5; 95% CI − 9.0 to 4.8) and hospital cost (β = − 2.137 ± 10.813; 95% CI − 23,331 to 19,056) with each calendar year increase on multivariate logistic regression analysis.ConclusionThe incidence of neonates with gastroschisis increased between 2010 and 2014. Incidence was highest in the West. No difference in mortality and resource utilization was observed.
