Ontario Audit Flags AI Scribe Hallucinations in Doctor Notes

Ontario's provincial auditor has found that an AI transcription system deployed for physician use fabricated clinical details and introduced errors into medical notes, raising direct patient safety concerns. The audit examined an AI scribe tool used by doctors to auto-generate clinical documentation. Auditors identified hallucinated content appearing in physician records, meaning the system invented details that were never spoken or intended. The report stops short of naming the specific vendor, but the findings apply pressure to a category of tools that has seen rapid adoption across Canadian and US health systems with minimal standardized oversight. Essentially: (Ontario Health, unnamed AI scribe vendor) deployed a documentation tool that fabricated clinical content without adequate real-world validation. - Auditors found hallucinated details embedded in physician notes, the kind of errors that can directly affect diagnosis and treatment decisions. - The audit calls for more rigorous validation before widespread clinical deployment, signaling a gap between procurement speed and safety standards. - No patient harm cases were confirmed in the audit, but the structural risk is documented. As AI scribes expand into healthcare globally, this audit represents one of the first government-level findings that the hallucination problem is not just theoretical in a clinical setting.
