Dual-Eligible and Medicare Advantage Stroke Patients Less Likely to Reach High-Quality Post-Acute Care
Stroke recovery depends heavily on what happens in the weeks and months after hospital discharge. Post-acute care - whether in a skilled nursing facility, through a home health agency, or via inpatient rehabilitation - shapes how much function patients regain and how quickly. Not all facilities are equal in quality, and access to the better ones is not evenly distributed. A cohort study published in JAMA Network Open finds that insurance type is one of the most consistent predictors of whether stroke survivors end up at high-quality facilities.
Specifically, patients who are dual-eligible - enrolled in both Medicare and Medicaid, a designation that typically signals lower income and higher medical complexity - and patients enrolled in Medicare Advantage plans were both less likely to receive post-acute care from skilled nursing facilities and home health agencies that scored in the higher quality tiers. The findings have direct implications for value-based care initiatives that aim to improve outcomes for the highest-need patients.
Why post-acute care quality matters in stroke recovery
Stroke is the leading cause of serious long-term disability in the United States, and much of the variation in long-term outcome is attributable to differences in rehabilitation quality and intensity during the post-acute period. A patient who receives aggressive, coordinated therapy in a high-performing facility within the first weeks after stroke typically regains more function than one who receives fragmented or lower-intensity care - even when the initial stroke severity is comparable.
Quality metrics for skilled nursing facilities and home health agencies are publicly reported through Medicare's care compare tools and reflect factors including patient outcomes, staffing levels, and inspection results. High-scoring facilities are not uniformly accessible, however: they may have admission criteria, geographic locations, or contracting arrangements that create barriers for certain patient populations.
What the study found
The cohort design allowed researchers to control for clinical characteristics and compare insurance types directly. Dual-eligible patients - those with both Medicare and Medicaid coverage, representing the most economically and medically vulnerable segment of the Medicare population - showed the largest disparity in access to high-quality post-acute providers. Medicare Advantage enrollees, despite having private insurance through Medicare-contracted plans, also showed reduced access compared to traditional fee-for-service Medicare patients.
The Medicare Advantage finding is particularly notable because these plans are often marketed as offering enhanced benefits and care coordination. The study suggests that, for stroke patients needing high-quality post-acute care, enrollment in Medicare Advantage does not translate into better access - and may actually be associated with lower access - compared with traditional Medicare.
Limitations and context
Cohort studies observe patterns without randomly assigning patients to insurance types, so the association between insurance status and post-acute care quality cannot be interpreted as purely causal. Unmeasured factors - patient preferences, geography, facility availability, discharge planner practices, and family support - all influence where patients go after hospital discharge. The study cannot fully disentangle the contribution of insurance type from these other variables.
The findings nonetheless add to a body of evidence suggesting that dual-eligible patients face structural disadvantages in accessing high-quality care across multiple settings, not only in acute care. As Medicare continues to expand value-based payment models that reward high-quality, cost-effective care, ensuring that the most vulnerable patients can access the facilities capable of delivering that care will be essential to achieving the equity goals those models are intended to advance.
