Abstract

Purpose: We aimed to describe the incidence, timing, and predictors of recurrence following inguinal hernia repair (IHR) in children.
Methods: We used the TRICARE claims database, a national cohort of >3 million child dependents of members of the U.S. Armed Forces. We abstracted data on children (2005-2014). Our primary outcome was recurrence (ICD9-CM diagnosis codes). We calculated incidence rates for the population and stratified by age, time from repair to recurrence, and multivariable logistic regression to determine predictors.
Results: Nine thousand nine hundred ninety-three children met inclusion criteria. Age at time of IHR was ≤1y in 37%, 2-3y in 23%, 4-5y in 16%, and 5-12y in 24%. Median follow-up time was 3.5y (IQR:1.6-6.1). 137 patients recurred (1.4%), with an incidence of 3.46 per 1000 person-years. Over half occurred in children 0-1y at repair (60%). The majority occurred within a year following repair (median 209 days [IQR:79-486]). Children 0-1y had 2.53 times greater odds of recurrence (compared to >5y). Children with multiple comorbidities had 5.45 times greater odds compared to those with no comorbidities.
Conclusions: The incidence of recurrence following IHR is 3.46 per 1000 person-years. The majority occurred within a year of repair. Children ≤1y and those with multiple comorbidities were at increased risk.
Level of evidence: Prognosis Study, Level II.
