When Algorithms Prescribe: A Cross-Sectional Study of Quality, Misinformation, and Engagement in Statin-Related Content on TikTok
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
public
Hosted for public use (ChatGPT, Claude, consumer apps). Anyone with a device can use it.
Interests
commercial
Prioritizes vendor or platform commercial interests (advertising, data, retention).
Agency
constraining
Channels patients toward predetermined pathways or substitutes for patient capabilities.
Editor's CAIHL read
One-sentence synthesis
Recommender-system delivery of medication misinformation; constraining agency because the patient is not the one initiating the query.
In the scan
How this item appeared in the daily scan
Editor's note: The algorithmic prescription is not the chatbot answer; it is the feed. The patient never asks; the feed offers. The framework patients use to evaluate AI tools has to extend to the recommender layer that delivers the tool's adjacent content.
Summary: medRxiv: Cross-sectional analysis of statin-related TikTok content — quality, misinformation, and engagement metrics — showing high-engagement videos disproportionately encode anti-statin claims at variance with current evidence.
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.
