documented ai-in-healthcare failures — what went wrong, why, and what might have helped, synthesised from public sources
For teams looking at prediction, triage, allocation, coverage and documentation tools. Questions drawn from the incidents, and signals the incidents point to after go-live, each linked to the incidents behind it and to standards and laws that cover the same ground. They are prompts, not a certification or a complete list; what fits depends on your setting.
