Clinical and Demographic Factors Linked to Low-Value Emergency Department Visits in Pediatric Patients With Spina Bifida.

PURPOSE

Identifying factors associated with emergency visits that could be delivered at lower cost sites may help guide population health strategies for pediatric patients with spina bifida.

MATERIALS AND METHODS

Emergency department encounters (2016-2023) by patients with spina bifida (younger than 18 years) in the Pediatric Health Information System were identified. Absence of clinical and imaging charges was defined as low-value emergency visit. We used a control population of patients (younger than 18 years) with obstructive/reflux uropathy who presented for emergency department encounters (2016-2023). Mixed-effects (with repeated individual measurements as random effect) logistic regression was fitted to model odds of low-value emergency visit.

RESULTS

In total, we included 22,672 emergency visits by patients with spina bifida. Of these, 20.7% of emergency visits were low value vs 17.7% in controls ( < .001). Costs related to low-value emergency visits account for 3.8% of all costs for emergency visit-related encounters in patients with spina bifida. Low-value emergency visits were associated with younger age (odds ratio [OR], 1.05 [1.04-1.06] per year younger), Hispanic/Latino ethnicity (OR, 1.21 [1.06-1.39] compared with non-Hispanics), Black race (OR, 1.35 [1.16-1.58] compared with White), public insurance (OR, 1.14 [1.01-1.29] compared with private insurance), and genitourinary encounter diagnosis (OR, 1.16 [1.04-1.30]). Using a standard patient, we found that the odds of low-value emergency visit across hospitals ranged from 0.31 to 5.36.

CONCLUSIONS

Younger age, Hispanic/Latino ethnicity, Black and other race, public insurance, and genitourinary encounter diagnosis were associated with higher odds of low-value emergency visits in pediatric patients with spina bifida. There was wide variation across hospitals, which warrants further investigation to elucidate best practices.
