This creates a paradox for payer economics—the "inflationary chronic use" concern assumes sustained adherence, but the actual problem is insufficient persistence. Under capitation, payers pay for 12 months of therapy ($2,940 at $245/month) for patients who discontinue and regain weight, capturing net cost with no downstream savings from avoided complications. The economics only work if adherence is sustained AND the payer captures downstream benefits—with 85% discontinuing by two years, the downstream cardiovascular and metabolic savings that justify the cost never materialize for most patients. ### Additional Evidence (extend) -*Source: [[2025-06-01-cell-med-glp1-societal-implications-obesity]] | Added: 2026-03-15* +*Source: 2025-06-01-cell-med-glp1-societal-implications-obesity | Added: 2026-03-15* The Cell Press review characterizes GLP-1s as marking a 'system-level redefinition' of cardiometabolic management with 'ripple effects across healthcare costs, insurance models, food systems, long-term population health.' Obesity costs the US $400B+ annually, providing context for the scale of potential cost impact. The WHO issued conditional recommendations within 2 years of widespread adoption (December 2025), unusually fast for a major therapeutic category. ### Additional Evidence (extend) -*Source: [[2025-03-01-medicare-prior-authorization-glp1-near-universal]] | Added: 2026-03-15* +*Source: 2025-03-01-medicare-prior-authorization-glp1-near-universal | Added: 2026-03-15* MA plans' near-universal prior authorization creates administrative friction that may worsen the already-poor adherence rates for GLP-1s. PA requirements ensure only T2D-diagnosed patients can access, effectively blocking obesity-only coverage despite FDA approval.

GLP-1s now demonstrate efficacy across three major organ systems (cardiovascular, renal, hepatic), which strengthens the multi-indication economic case for chronic use. The 62.9% MASH resolution rate suggests GLP-1s could prevent progression to late-stage liver disease and transplantation, though the Value in Health Medicare study showed only $28M MASH savings—surprisingly small given clinical magnitude, likely because MASH progression to transplant takes decades and falls outside typical budget scoring windows. + --- Relevant Notes: diff --git a/domains/health/glp-1-multi-organ-protection-creates-compounding-value-across-kidney-cardiovascular-and-metabolic-endpoints.md b/domains/health/glp-1-multi-organ-protection-creates-compounding-value-across-kidney-cardiovascular-and-metabolic-endpoints.md index 8dab4f1b..22e50070 100644 --- a/domains/health/glp-1-multi-organ-protection-creates-compounding-value-across-kidney-cardiovascular-and-metabolic-endpoints.md +++ b/domains/health/glp-1-multi-organ-protection-creates-compounding-value-across-kidney-cardiovascular-and-metabolic-endpoints.md @@ -32,10 +32,16 @@ For value-based care models and capitated payers, this multi-organ protection cr ### Additional Evidence (extend) -*Source: [[2025-12-23-jama-cardiology-select-hospitalization-analysis]] | Added: 2026-03-16* +*Source: 2025-12-23-jama-cardiology-select-hospitalization-analysis | Added: 2026-03-16* SELECT trial exploratory analysis (N=17,604, median 41.8 months) shows semaglutide reduces ALL-CAUSE hospitalizations by 10% (18.3 vs 20.4 per 100 patient-years, P<.001) and total hospital days by 11% (157.2 vs 176.2 days per 100 patient-years, P=.01).
