Medicaid managed care organization coverage is associated with lower emergency department use and higher follow-up after hospital discharge, but important gaps remain—particularly higher readmission risk among older adults and underutilization of key care coordination services. A study from PROPEL team members examined differences in post-discharge utilization between Medicaid managed care and fee-for-service programs.
We asked the study team to explain their findings.
Why is this research noteworthy?
Managed care is an increasingly common way for state Medicaid agencies to pay for services and coordinate care for their members. It involves paying a lump sum to a health plan (called a “managed care organization”) who then pays for healthcare services and coordinates care for a group of members. This may increase budget predictability for states, but evidence comparing quality of care between managed care and fee-for-service (when the state directly pays for services and coordinates care) is limited and mixed.
What are the top takeaways from the research?
* We demonstrate that across 1.65 million hospital discharges, managed care enrollment was associated with lower emergency department use (−1.2 percentage points for ages 18–49; −2.2 percentage points for ages 50+). Managed care was associated with substantially higher clinic follow-up rates (+10.6 and +20.4 percentage points, respectively), but overall follow-up remained modest (29% for younger adults; 39% for older adults).
* Surprisingly, we found that among older adults, managed care was associated with higher readmission risk (+1.6 percentage points), highlighting potential gaps in post-acute care and/or care continuity.
* We highlight that a form of post-hospital discharge visits (which includes care coordination services)—Transitional Care Management visits—were rarely used (occurred after <2% of discharges), suggesting limited uptake of this kind of visit by Medicaid agencies and/or clinicians.
Does this build on previous findings from your lab, or other researchers at UTSW?
Yes – Prior work at UT Southwestern has examined care delivery, utilization, and the impact of insurance design on patient outcomes. This study builds on that foundation by focusing specifically on the post-discharge period.
How does this research advance the field?
Altogether, these findings provide important evidence that managed care may improve aspects of care coordination—such as clinic follow-up and reduced reliance on the emergency department after hospital discharge—while also revealing persistent challenges, including increased readmission risk in managed care and low uptake of transitional care services. This highlights the need for more targeted strategies to improve post-discharge care and to ensure that access to post-acute care are equitable between Medicaid managed care and fee-for-service.
