Identifying risk factors for enteral access procedures in neonates with congenital diaphragmatic hernia: A novel risk-assessment score

Background/Purpose: The purpose of this study was to evaluate the characteristics of neonates with congenital diaphragmatic hernia (CDH) undergoing enteral access procedures (gastrostomy or jejunostomy) during their initial hospitalization, and establish a clinical scoring system based on these characteristics. Methods: Data were obtained from the multicenter, multinational CDH Study Group database (CDHSG Registry) between 2007 and 2019. Patients were randomly partitioned into model-derivation and validation subsets. Weighted scores were assigned to risk factors based on their calculated beta-coefficients after logistic regression. Results: Of 4537 total patients, 597 (13%) underwent gastrostomy or jejunostomy tube placement. In the derivation subset, factors independently associated with an increased risk for enteral access included oxygen requirement at 30-days, chromosomal abnormalities, gastroesophageal reflux, major cardiac anomalies, ECMO requirement, liver herniation, and increased defect size. Based on the devised scoring system, patients could be stratified into very low (0-4 points; <10% risk), low (5-6 points; 10-20% risk), intermediate (7-9 points; 30-60% risk), and high risk (>= 10 points; 70% risk) groups for enteral access. Conclusion: This study identifies risk factors associated with enteral access procedures in neonates with congenital diaphragmatic hernia and establishes a novel scoring system that may be used to guide clinical decision making in those with poor oral feeding.

Automated summary

This study evaluated the characteristics of neonates with congenital diaphragmatic hernia undergoing enteral access procedures during their initial hospitalization and established a clinical scoring system based on these characteristics to stratify patients into different risk groups for enteral access.
