May 14, 2026

AI Summary

An audit by the Office of the Auditor General of Ontario found that many AI Scribe systems used by healthcare providers frequently made errors in patient notes, including incorrect drug information and fabricated details. The report highlights concerns over the evaluation criteria used for selecting these AI tools, which may have prioritized vendor presence over accuracy and safety.

The audit evaluated 20 AI Scribe systems used in Ontario's healthcare sector.
60% of the systems mixed up prescribed drugs in patient notes.
Nine out of 20 systems fabricated information and made unverified treatment suggestions.
Twelve systems inserted incorrect drug information, while 17 missed key details about patients' mental health issues.
The evaluation criteria weighted domestic presence heavily, while accuracy and bias controls were minimally considered.
OntarioMD recommended manual review of AI-generated notes, but no mandatory attestation feature exists in the approved systems.
Over 5,000 physicians in Ontario are using the AI Scribe program, with no reported patient harms linked to the technology.
