Association of Sociodemographic Factors with Adherence to Age-Specific Guidelines for Asymptomatic Umbilical Hernia Repair in Children

Abstract

Importance: Current guidelines recommend delaying repair of asymptomatic umbilical hernia in children until after age 4 to 5 years to allow for spontaneous closure. Objective: To examine the association of sociodemographic factors with adherence to age-specific guidelines for asymptomatic umbilical hernia repair in children. Design, Setting, and Participants: In this multicenter retrospective cohort study, children 17 years and younger who underwent umbilical hernia repair from January 2013 to June 2018 at 47 freestanding children's hospitals participating in the Pediatric Health Information System database were eligible for study inclusion. Children who underwent multiple procedures, repair of recurrent hernias, or had missing sociodemographic data were excluded. Exposures: Early umbilical hernia repair was defined as repair at 3 years or younger. Emergent or urgent presentation was defined as repair performed during the same encounter or within 2 weeks of an emergency department visit, respectively. Patients were categorized by sex, race/ethnicity, insurance type, income quintile, and presence of complex chronic conditions. Main Outcomes and Measures: Multivariable mixed-effects logistic regression was used to evaluate the association of sociodemographic factors with the odds of early repair after adjusting for emergent or urgent presentation and hospital-level effects. Results: Of the 25877 included children, 13817 (53.4%) were female, 14143 (54.7%) had public insurance, and the median (interquartile range) age was 5.0 (3.0-6.0) years. Following adjustment, increased odds of early repair was associated with public insurance (public vs commercial insurance: odds ratio [OR], 1.46; 95% CI, 1.36-1.56; P
