Quasi-experimental analysis shows mixed effects of expanded supplemental benefits on acute care utilization in Medicare enrollees, suggesting a need for further assessment.

Key Points

The aim is to evaluate if expanded supplemental benefits in Medicare Advantage plans affect acute care usage by enrollees.
Quasi-experimental design using staggered difference-in-differences models
Data analyzed includes a random 20% sample of MA enrollees from 2017–2022
Utilization measured by adverse health events indicators: emergency department use, hospitalizations, and re-admissions.
Offering any PHR reduced re-admissions by -2.82 percentage points (95% CI: -4.78, -0.86) for highly frail non-dual enrollees.
Offering ≥ 2 expanded PHR reduced hospitalizations by -1.79 percentage points (95% CI: -2.61, -0.98) and ED use by -1.76 percentage points (95% CI: -2.38, -1.14).
Offering ≥ 2 SSBCI reduced ED use by -3.51 percentage points (95% CI: -4.96, -2.05) and hospitalizations by -2.05 percentage points (95% CI: -3.12, -0.099).
