Is initiation of Medicaid home and community-based services (HCBS) associated with changes in acute services use?In this cohort study among 1218 older adults across 11 states, Medicaid HCBS initiation was associated with a 24% decrease in within-person probability of emergency department use and a 32% decrease in inpatient discharge.Results of this study suggest that, among older adults with unmet need for Medicaid-funded long-term services and supports, initiation of Medicaid HCBS may reduce reliance on costly acute care services.
