Timing and Intensity of Early Intervention Service Use and Outcomes Among a Safety-Net Population of Children

Key Points Question What is the timeliness and service intensity of children enrolled in early intervention, and is service intensity associated with greater gains in function? Findings In this cohort study, more than half of the study children received delayed early intervention access and most received low-intensity early intervention services. An additional hour per month of early intervention services was associated with a 3-point gain in functional outcomes. Meaning Linking clinical and early intervention records could help integrate data to track early intervention–eligible children and improve early intervention timeliness, service intensity, and outcomes.
