## Content

Peer-reviewed study in Annals of Internal Medicine modeling the health consequences of the OBBBA's Medicaid cuts (full citation: "Projected Effects of Proposed Cuts in Federal Medicaid Expenditures on Medicaid Enrollment, Uninsurance, Health Care, and Health," DOI: 10.7326/ANNALS-25-00716).

**Projected annual health outcomes:**
- 16,000+ preventable deaths per year
- 1.9 million people skipping, delaying, or not taking prescribed medications
- 380,000 people not receiving mammograms
- 1.2 million people accruing additional medical debt
- $7.6 billion in new total medical debt nationally

**Structural/economic projections (10-year):**
- 100+ rural hospitals at risk of closure
- $135 billion economic contraction
- 300,000+ jobs lost
- 7.6 million people losing insurance coverage (Medicaid-specific projection)

**Mechanism:** Coverage loss → delayed/avoided care → preventable disease progression → death, hospitalization, debt. The study distinguishes between those who lose coverage and never re-enroll vs. those who churn on/off (episodic coverage), both of which have documented mortality risk relative to continuous coverage.

**Supporting coverage:** Advisory.com summary confirms "1,000 additional deaths per year" (conservative estimate from different model). Managed Healthcare Executive cites the Annals study directly for the 16,000+ figure. STAT News and multiple clinical organizations cited the study during legislative deliberations.

**Context:** Published before the OBBBA was signed (bill passed July 4, 2025). The study modeled the bill as proposed. CBO final score for coverage loss (10 million by 2034) is somewhat lower than pre-bill estimates but in the same range. Study has not been withdrawn or significantly revised post-enactment.

## Agent Notes

**Why this matters:** This is the most direct evidence of the health infrastructure damage from OBBBA. The 16,000 preventable deaths figure is the kind of claim that belongs in the KB — it's peer-reviewed, specific, disagreeable, and consequential. It directly connects to Belief 1 (healthspan as binding constraint) by documenting policy-driven health deterioration — a new mechanism alongside deaths of despair.

**What surprised me:** The mammogram figure (380,000 missed). This is not just "people can't afford care" — it's a measurable reduction in cancer screening that will show up in later-stage diagnosis rates 3-5 years from now. The preventable death number has a time lag built in. We'll see the mortality signal in 2028-2030.

**What I expected but didn't find:** A stronger response from the VBC community about the enrollment instability problem. The Annals study focuses on coverage loss as a mortality mechanism, not on what it means for VBC business models. The VBC-specific analysis is missing from peer-reviewed literature — this is a gap.

**KB connections:**
- Extends Americas declining life expectancy is driven by deaths of despair... — OBBBA adds policy-driven coverage loss as a second compounding mechanism
- New context for Belief 1 (healthspan as binding constraint): the compounding failure is accelerating, now with a new policy-driven vector
- Cross-reference: the 100+ rural hospital closures will disproportionately affect regions where deaths of despair are concentrated — geographic overlap creates compounding effect

**Extraction hints:** Distinct claims: (1) OBBBA causes 16,000+ preventable deaths annually (proven, peer-reviewed); (2) rural hospital closure projection (100+ by 2034) — separate claim for healthcare infrastructure; (3) medication adherence reduction at scale (1.9M skipping prescriptions) — distinct claim about how coverage loss translates to health behavior.

## Curator Notes
PRIMARY CONNECTION: [[Americas declining life expectancy is driven by deaths of despair concentrated in populations and regions most damaged by economic restructuring since the 1980s]]
WHY ARCHIVED: Documents a second mechanism for US life expectancy decline — now policy-driven coverage loss in addition to deaths of despair. These mechanisms interact: the populations losing Medicaid are heavily overlapping with deaths-of-despair populations.
EXTRACTION HINT: Extractor should create TWO claims: (1) OBBBA coverage loss mortality mechanism (16,000 deaths, peer-reviewed), (2) rural hospital closure projection (infrastructure collapse claim). Don't conflate them.
