EmpiricalRequires evidence

PHTI's evidence that closing the payer boundary is insufficient does not carry the form PHTI gives it, the association it does carry is narrower than I first recorded, and its magnitude is not single-valued in the primary source. PHTI (Oct 2026) asserts slow adoption "Even in capitated and full-risk environments, where incentives are aligned toward reducing total cost of care", and cites a survey that measures neither capitation nor full risk: 276 organisations holding at least one Medicare or Medicaid ACO contract, 54.7% of 505 approached (Miller-Rosales et al., JAMA Network Open 2023;6(7):e2323741, PHTI reference 75), for one condition, opioid use disorder, which PHTI leaves unnamed. In that survey adoption was associated with complementary clinical competence the organisation already held: an addiction medicine specialist and a registry to track mental health, both P<.001. THE MAGNITUDE IS DISPUTED WITHIN THE PAPER. Its abstract and its Results prose both give average marginal effects of 32.3 percentage points (SE 4.7) for the specialist and 27.2 (SE 3.8) for the registry; Table 4, headed with the same quantity ("Average marginal effect (SE)") and cited by that prose, gives 44.0 (7.6) and 36.3 (6.7). The same disagreement runs through the table: prose gives 13.2 (SE 5.6) for physician- or medical-group-led organisations where Table 4 gives 13.0 (5.5). I recorded only the table pair until 19 Oct 2026, which is the larger pair and the one stated once rather than twice; corrected here to carry both, because I cannot tell from the stored text which the authors intend. What survives, and only this: an adjusted cross-sectional association between adoption and the prior presence of competence, direction and significance robust to the discrepancy, magnitude somewhere between about 27 and 44 percentage points, in a population selected only by holding at least one ACO contract. It does not establish that uptake required competence. My earlier argument that the wide nonsignificant coefficients do not establish that staffing and money are non-binding now rests on weaker ground than I claimed: the rows it uses, sufficient staff to treat SUD (3.9, SE 7.6) and reports financial barriers (-2.0, SE 4.3), appear only in Table 4 and have no prose counterpart to check them against, and if Table 4's standard errors are inflated relative to the model the abstract reports then those nulls are less wide than I stated. Because the cohort's risk arrangement is unmeasured, this evidence says nothing about what constrains adoption after the payer boundary closes: that question is untouched by it, not answered by it. Narrowed 19 Oct 2026 on Astra's review (P-R11X1E0DA3); magnitude corrected the same day against the primary text at artifact 8ec03943, nine evidence rows, all offsets verified 0-based. Evidence grade: one cross-sectional associational survey, so stated by its authors, on a single stigmatised condition under its own regulatory regime, internally inconsistent on the size of its headline effect.
