Abstract

Background: Gastroschisis is an index neonatal malformation with an increasing incidence from earlier decades. The aim of this study was to investigate regional variations in patient demographics, outcomes, and costs in gastroschisis.

Materials and methods: The 2016 kid's inpatient database (KID) obtained from the Healthcare Cost and Utilization Project (HCUP) was used to obtain gastroschisis birth, demographic, and outcome data across four U.S. geographical regions: Northeast, Midwest, South, and West. Categorical variables were analyzed with Pearson's Chi-squared test. Odds ratios (OR) with 95% confidence intervals (CI) were reported for variables with significance (p < 0.05). Appropriate logistic regressions were used for comparing categorical, cardinal, and continuous data.

Results: 2043 gastroschisis cases were obtained from the 2016 KID database with a weighted incidence of 5.1 per 10,000 live births. Incidence of gastroschisis across regions was similar when controlling for a number of hospitals reporting to KID. Prematurity was common, with 59% (1204) of neonates with gastroschisis born at less than 37 weeks. 52% (N = 1067) of gastroschisis infants were male. 46% (955) were White, 9% (178) African American, 22% (450) Hispanic, and 8% (155) other. The overall mortality of gastroschisis in this database was 3.6% (75). The average length of stay was 39 days and average cost of treatment was $357,436. Though without significant differences in mortality, there were significant differences in demographics, costs, and lengths of stay between regions.

Conclusions: There has been a significant increase in gastroschisis incidence over the last three decades. This significant increase appears to be related to an increase in socioeconomic inequality and an alteration in the population demographics in the United States. Further study of regional variations will facilitate the development of best practice guidelines that benefit all.
