Study methods
- Design: difference-in-differences analysis of 2019-2023 claims.
- Intervention group: 208 PCPs who adopted supported full-risk value-based care in 2022.
- Comparison group: 3,657 similar PCPs that maintained prior payment models.
- Eligibility: PCPs with at least 50 traditional Medicare patients in panel.
- Primary access outcomes: new TM patients seen per year and months panels remained open.
Key findings
- On average, VBC adopters saw 8 more new traditional Medicare patients annually than nonadopters.
- Adopters kept panels open to new traditional Medicare patients 0.7 more months per year than nonadopters.
Method interpretation
Difference-in-differences is appropriate for evaluating pre/post adoption effects in real-world operations. As with all observational analyses, unmeasured differences may remain, but the design strengthens confidence in directional findings for access strategy and contract decisions.
