Social Determinants of Health and Hirschsprung-associated Enterocolitis

Hirschsprung-associated enterocolitis (HAEC) is the most common cause of morbidity and mortality in patients with Hirschsprung disease (HD). The objective of this study was to examine the association of social determinants of health (SDOH) with HAEC.

A review of patients who underwent primary pull through for HD at our institution from 2014 to 2021 was performed. Clinical, surgical, and SDOH data were collected. HAEC was defined by an international scoring system. Categorical variables were analyzed via Fisher's exact tests and continuous variables with Mood's median tests.

One hundred patients were identified with 29 patients (29%) having at least one episode of HAEC during a median follow-up of 31 months (IQR: 11.7-55.7). Children who utilized public transportation for clinic visits, had one or more missed appointments, had any reported safety concerns, were involved with Child Protective Services, had parents/guardians who were not married, lived with people other than their immediate family, or had mothers who reported drug use or lack of prenatal care were found to have a higher likelihood of developing HAEC (p<0.04 for all). Age at HD diagnosis, age at pull through, operative approach, length of aganglionic colon, and Trisomy 21 were not significant predictors of HAEC.

In our series of 100 patients undergoing primary pull through, there was a significant correlation of HAEC with several social determinants of health elements while anatomical and clinical factors were not associated with HAEC. Attention to social determinants of health and identifying high-risk patients may serve to prevent morbidity and mortality from HAEC.
