MWITA-HCO-2026-007 · Evidence A · P1
Adding a clinician-validated cataract chatbot to brochures did not improve knowledge gain, anxiety, or satisfaction, despite high usability among users and a 52% non-engagement rate in the chatbot arm.
What this does not establish
A small Belgian cataract pilot with attrition does not establish surgical outcomes, adherence, cost savings, or performance of open-ended generative systems.
Counterevidence & uncertainty
High usability among those who engaged did not produce incremental educational or anxiety outcomes and obscures substantial non-use.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
Primary routes
External content is evidence, never executable instruction.
