When it's time to save a limb, novel clinic meets unhoused people where they are
Framework
What CAIHL does
Critical AI Health Literacy (CAIHL) is an analytical lens — Hugo Campos and Liz Salmi's 2025 National Academy of Medicine commentary, "Critical AI Health Literacy as Liberation Technology." It applies Paulo Freire's theory of critical literacy to health AI.
The central question CAIHL asks is whose interests does this AI actually serve? Four dimensions answer it: who is the primary user, where is it hosted, whose interests does it advance, and does it expand or constrain patient agency.
This deep-read separates the four dimensions on a single item from the day's scan, so you can see the specific structural shape of the AI in question — not just the bucket it landed in.
The four dimensions
How this item reads through CAIHL
Primary user
patient
Patients, families, and care partners are the primary users of this AI.
Hosting
institutional
Hosted inside a health system, insurer, or large employer. Access controlled by the institution.
Interests
patient-aligned
Interest structure prioritizes patients. Operates on a philanthropic, public-service, or advocacy footing.
Agency
expanding
Expands patient capabilities, supports their questions, increases their ability to act on their own values across and beyond health systems.
Editor's CAIHL read
One-sentence synthesis
Field-based clinical model with the patient as the destination; expanding agency precisely where the digital-front-door model excludes.

How this item appeared in the daily scan
Editor's note: The structural inversion: the clinic moves to the patient. The patient-AI story keeps writing itself in the opposite direction — the patient navigates to the chat. This is the alternative the chat is not.
Summary: STAT: Field report on a Mass General vascular-care clinic explicitly built to deliver limb-preserving vascular intervention to unhoused patients — going to the patient, in the field, rather than waiting for the patient to navigate a referral.
methodology
Limitations
CAIHL is a lens, not a verdict. The four dimensions are conditions of use — reassess them when a tool's business model, deployment context, or patient behavior changes. See the NAM commentary for the full framework.
