Introduction:
Gastroschisis is the most common newborn abdominal wall defect. Gastroschisis classification
is based on the absence (simple gastroschisis (SG)) or presence (complex gastroschisis
(CG)) of bowel morbidity. The severity of critical organ dysfunction with gastroschisis
is unknown.
Methods: This was a multicenter, retrospective cohort study of infants with gastroschisis
(birth weight ≥ 1.8kg & gestational age ≥ 35 weeks) admitted to UF Health NICU between
1/1/2012 and 4/1/2023 and Johns Hopkins NICU between 7/1/2016 - 12/31/2024. All data
was collected from the electronic health record. CG was defined as the presence of
atresia, necrosis, perforation, volvulus, jejunostomy, resection, or short bowel syndrome.
Hourly organ dysfunction was quantified by the neonatal sequential organ failure assessment
(nSOFA) score (measures respiratory, cardiovascular, and hematologic dysfunction with
a range of 0-15 (severe)).
Results: We identified 120 patients with gastroschisis (49% male; 90 with simple gastroschisis).
Compared to patients with SG, neonates with CG had greater maximum nSOFA scores (median
2 (IQR 0, 4) vs 3 (1, 7), p=0.02). The coefficient of variation on cumulative nSOFA
scores calculated at 24-hour intervals after birth as a measure of organ dysfunction
heterogeneity for SG patients was 278-332% and was 216-266% for CG patients.
Conclusions: This is the first high-granularity quantification of critical organ dysfunction
in gastroschisis patients. We found a low overall severity of critical organ dysfunction
among all patients. Substantial heterogeneity was present in both groups. The nSOFA
may help to identify a subset of patients with critical organ dysfunction outside
of bowel morbidity.
