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 (< 18-years-old) in Pediatric Health Information System were identified. Absence of clinical and imaging charges was defined as low-value emergency visit. We utilized a control population of patients (<18-years-old) 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. 20.7% of these emergency visits were low-value versus 17.7% in controls (p<0.001). 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 [OR 1.05 (1.04 - 1.06) per year younger], Hispanic/Latino [OR 1.21 (1.06 - 1.39) compared to non-Hispanics], black [OR 1.35 (1.16 - 1.58) compared to white], public insurance [OR 1.14 (1.01 - 1.29) compared to 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 for low-value emergency visits in pediatric patients with spina bifida. There was wide variation across hospitals that warrants further investigation to elucidate best practices.
