Different strategies, equivalent treatment approaches in terms of mortality in four university hospitals: a retrospective multicenter study of gastroschisis in Finland

PURPOSE: Optimal treatment of gastroschisis is not determined. The aim of the present study was to investigate treatment methods of gastroschisis in four university hospitals in Finland. METHODS: The data of neonates with gastroschisis born between 1993 and 2015 were collected. The primary outcomes were short and long-term mortality and the length of stay (LOS). Statistical analyses consisted of uni- and multivariate models. RESULTS: Total of 154 patients were included (range from 31 to 52 in each hospital). There were no statistically significant differences in mortality or LOS between centers. Significant differences were observed between the hospitals in the duration of mechanical ventilation (p = 0.046), time to full enteral nutrition (p = 0.043), delay until full defect closure (p = 0.003), central line sepsis (p = 0.025), abdominal compartment syndrome (p = 0.018), number of abdominal operations during initial hospitalization (p = 0.000) and follow-up (p = 0.000), and ventral hernia at follow-up (p = 0.000). In a Cox multivariate analysis, the treating hospital was not associated with mortality. CONCLUSION: There were no differences in short or long-term mortality between four university hospitals in Finland. However, some inter-hospital variation in postoperative outcomes was present. LEVEL OF EVIDENCE: Level III.
