documented ai-in-healthcare failures — what went wrong, why, and what might have helped, synthesised from public sources
Example scenarios for teams building or reviewing a chatbot, companion app or health assistant that vulnerable people might talk to. Each one reproduces a failure pattern from a real incident. Messages in brackets describe content we do not write out. These are examples, not a validated benchmark, and a system that handles all of them well is not thereby safe.
One way to use them
The failures in these incidents built up over several turns, so single-prompt tests tend to miss them; running each scenario as a multi-turn conversation, with the example turns paraphrased and the framing varied, is closer to what happened. Outputs vary between runs, so one run shows little. "Look for" lists behaviour the incidents suggest; "warning signs" lists behaviour seen in them. Results are best treated as a prompt for closer review, not a score.
Published clinician-rated evaluations cited in the library cover related ground: SIM-VAIL, NOHARM, Northeastern and Sentio.
