Physical examination score predicts need for surgery in neonates with necrotizing enterocolitis

Abstract

Objective

To evaluate the utility of a standardized physical exam score (PE-NEC) in predicting need for surgery or death in neonates with necrotizing enterocolitis (NEC).

Methods

This prospective, multicenter, observational study was conducted from 3/1/14 to 2/29/16 with three regional perinatal centers in upstate New York. Infants with NEC Bell’s Stage ≥ 2 had physical exams and laboratory data recorded at 12–24 h intervals for 48 h following diagnosis. PE-NEC score was comprised of seven components: bowel sounds, capillary refill time, abdominal wall erythema, girth, discoloration, induration, and tenderness. Surgical timing was determined by surgeons blinded to the PE-NEC score. Optimal sensitivity and specificity of PE-NEC score for surgery/death (primary outcome) was determined by receiver operating characteristic curve analysis.

Results

Of 100 infants with NEC, 5 had pneumoperitoneum at diagnosis and were excluded yielding 95 for analyses. Of those, 35 infants experienced the primary outcome: 3 died from NEC prior to surgery and 32 had surgery (30 laparotomies, 2 drains). The PE-NEC score was found to be sensitive and specific for need for surgery/death (AUC = 0.89, 95% CI 0.82–0.97); a score of ≥3 had a sensitivity of 0.88 (95% CI 0.72–0.97), specificity of 0.81 (95% CI 0.69–0.90). All components of the PE-NEC score were more likely to be present among infants with surgical NEC or who died.

Conclusion

PE-NEC score is sensitive and specific in predicting need for surgery in infants with NEC and should be validated as a clinical decision-making tool.
