Doctors’ AI Systems Are Hallucinating Nonexistent Medical Issues During Appointments With Patients

Ontario’s auditor general found inaccuracies in all 20 approved AI medical scribe tools it tested, including fabricated, missing, or wrong information.

Officials said the problems were identified in testing, not live patient visits, but the tools are already used by about 5,000 doctors in Ontario.

The findings raise concerns that errors in AI-generated clinical notes could affect treatment decisions and patient safety.

The audit adds scrutiny to fast-growing healthcare AI tools, including vendors such as OpenEvidence.
