TL;DR
An Ontario audit of 20 AI note-taking systems used in healthcare found that most systems frequently made errors, including fabricating information and missing key details. The findings highlight significant concerns about AI accuracy in critical medical documentation.
The Ontario Office of the Auditor General has reported that 20 AI-powered medical note-taking systems approved for use in the province routinely produce inaccurate and sometimes fabricated patient records, raising concerns about safety and reliability.
The audit evaluated 20 AI Scribe systems used by healthcare providers across Ontario, using simulated doctor-patient recordings. It found that nine of these systems fabricated information, such as suggesting treatments or symptoms not discussed during consultations. Additionally, 12 systems inserted incorrect medication details into patient notes, and 17 missed critical mental health information discussed during recordings. Six systems fully or partially overlooked key mental health issues.
OntarioMD, an organization supporting healthcare technology adoption, recommended that physicians manually review AI-generated notes for accuracy. However, the report notes that none of the approved systems include mandatory attestation features to verify note correctness, increasing risks of errors going unchecked.
Why It Matters
The findings raise serious questions about the safety and reliability of AI tools used in medical documentation, which could impact patient care and safety. Errors such as fabricated treatment suggestions or incorrect medication records could lead to misdiagnoses or inappropriate treatments. The report also highlights regulatory and evaluation shortcomings that may have allowed subpar systems to be approved, potentially exposing patients to harm and undermining trust in AI-assisted healthcare.

Background
The use of AI for medical note-taking has been expanding in Ontario as part of broader efforts to improve healthcare efficiency. The AI Scribe program was launched to assist clinicians by automating documentation tasks, with more than 5,000 physicians participating. Prior to this, concerns about AI accuracy in healthcare have been raised internationally, but this is the first comprehensive audit in Ontario to evaluate the actual performance of approved systems in simulated settings.
“Nine out of 20 AI systems fabricated information or made suggestions to treatment plans not discussed in the recordings.”

What Remains Unclear
It is still unclear how widespread these inaccuracies are in real-world clinical settings, as the audit was based on simulated recordings. The Ontario Ministry of Health has not reported any known patient harms linked to the AI Scribe systems so far, and the full impact of these errors remains to be assessed.
