There are limited reports of neurobehavioral outcomes of children supported on extracorporeal membrane oxygenation (ECMO). This observational study aims to characterize the long-term (≥1 year) neurobehavioral outcomes, identify risk factors associated with neurobehavioral impairment, and evaluate the trajectory of functional status in pediatric ECMO survivors. Pediatric ECMO survivors ≥1-year postdecannulation and ≥3 years of age at follow-up were prospectively enrolled and completed assessments of adaptive behavior (Vineland Adaptive Behavior Scales, Third Edition [Vineland-3]) and functional status (Functional Status Scale [FSS]). Patient characteristics were retrospectively collected. Forty-one ECMO survivors cannulated at 0.0–19.8 years (median: 2.4 [IQR: 0.0, 13.1]) were enrolled at 1.3–12.8 years (median: 5.5 [IQR: 3.3, 6.5]) postdecannulation. ECMO survivors scored significantly lower than the normative population in the Vineland-3 Adaptive Behavior Composite (85 [IQR: 70, 99], P < 0.001) and all domains (Communication, Daily Living, Socialization, Motor). Independent risk factors for lower Vineland-3 composite scores included extracorporeal cardiopulmonary resuscitation, electrographic seizures during ECMO, congenital heart disease, and premorbid developmental delay. Of the 21 patients with impaired function at discharge (FSS ≥8), 86% reported an improved FSS at follow-up. Pediatric ECMO survivors have, on average, mild neurobehavioral impairment related to adaptive functioning years after decannulation. Continued functional recovery after hospital discharge is likely.
