This pragmatic, cluster-randomized trial will evaluate whether a comprehensive CalAIM-aligned care model consisting of Enhanced Care Management, selected Community Supports, Transitional Care Services, and residential care coordination improves population health outcomes among high-risk Medi-Cal managed care members in California compared with usual CalAIM service delivery. The intervention is intended to improve continuity of care after discharge, reduce potentially avoidable utilization, increase successful linkage to outpatient and social supports, and improve community tenure and patient-reported outcomes.
