This resource analyzes the drivers of cost for Medicare-Medicaid beneficiaries, particularly looking at the differences between persistent and transient high costs.
- We know surprisingly little about the drivers of costs for dually eligible Medicare and Medicaid beneficiaries, and even less about the drivers over time—that is, how much spending is transient versus persistent.
- This study used Medicare-Medicaid Linked Enrollee Analytic Data Source from 2008-2010 to account for the full cost incurred by these patients.
- More than half of patients (54.8 percent) remained high-cost over all three years. These patients were younger than transiently high-cost patients, with fewer medical co-morbidities and greater intellectual impairment.
- Most spending for persistently high-cost patients was related to long-term care, and very little was for potentially preventable hospitalizations.
- Strategies to control costs may be more effective if they target long-term care spending, rather than potentially preventable hospitalizations.
