Oregon Medicaid Priority-Setting – Center for Health Decision Science

CHDS faculty Ankur Pandya and colleagues examined Oregon’s Medicaid priority‑setting experiment as a case of participatory governance in a recently published article. The authors focused on the Oregon Health Services Commission (OHSC), an eleven‑person citizen body established in 1989 to create a prioritized list of condition–treatment pairs for Medicaid coverage based on cost-effectiveness and public values.

The researchers analyzed meeting minutes and internal documents from 1990–1991 using reflexive thematic analysis in ATLAS.ti. They reviewed Commission and subcommittee minutes, internal session transcripts, community hearing notes, testimony from clinicians and advocates, and a mid‑term progress report to the legislature. Their analysis identified themes related to commissioners’ emotional experiences, technical challenges in developing and applying cost-effectiveness methods, and the evolving role of judgement in the priority‑setting process.

The article reported that the OHSC faced limited data, methodological uncertainty, compressed timelines, and growing public pressure, leading to frustration and conflict among commissioners. As technical approaches proved difficult to implement, commissioners increasingly relied on collective judgment, including hand adjustments to a ranked list developed through cost‑effectiveness calculations and public input. The authors argued that the Commission’s reliance on judgment reflected the inherent subjectivity of cost‑effectiveness analysis and participatory governance, and that its key innovation was vesting these decisions in a citizen commission rather than in experts or elected officials.
