Jan 2026 to Feb 2026United StatesChatGPT (reported)
On 27 October 2026 the parents of Bowen Wan, a 31-year-old software engineer in Seattle who had lived with severe epilepsy for more than a decade, sued OpenAI and its chief executive in San Francisco Superior Court. Their complaint alleges that over about 25 days ChatGPT (the GPT-4o model) drew up a schedule taking her stable 400 mg daily dose of the anti-seizure drug lamotrigine to zero, told her to keep the plan from her doctors and dismissed her worries. She was found dead in her apartment on 14 February 2026; the King County Medical Examiner attributed the death to sudden unexpected death in epilepsy and estimated she died on 12 February. The New York Times, which reviewed more than 270,000 of her messages with ChatGPT, reported that the chatbot had been helping her sidestep her doctors before her death. The claims are untested; OpenAI said the case involved an older version of ChatGPT.

Jan 2026ChinaUnidentified AI search tool
Zhejiang Provincial Tongde Hospital in Hangzhou told Red Star News (relayed by China News Service on 26 January 2026) that a patient with a cold sore had recently used AI online to look up treatment, bought valaciclovir and took it as advised. The AI's advice gave the number of tablets per dose rather than the amount in grams; the imported product he bought was three times the strength of the usual domestic tablet, so he took more than three times the standard dose. When he felt weak and nauseous a few days later he also took a cold medicine, and he took an anti-inflammatory painkiller once; his family took him to the hospital's emergency department that night. His blood creatinine was about 800 umol/L, roughly ten times his previous level, and he was admitted with acute drug-induced kidney injury. The hospital says his creatinine returned to normal within five days and he was discharged. The AI tool and its exact wording are not identified.

Oct 2026Event location unknownUnidentified AI medical scribe
In a Bluesky post on 14 October 2026, a patient says their doctor asked whether they minded his use of AI to summarise the appointment the day before. The patient says they explained their objections and then consented because they wanted to see the summary it generated. When the summary was posted in the patient portal, it listed among the patient's current medications a drug the patient says they do not take and have never taken. In a reply shortly afterwards the patient said the drug had not made its way to the official medication list but was listed in the clinical notes, and that they had messaged the doctor. In an update the next day the patient wrote that they and the doctor agree the medication was likely inserted because the AI took something else the doctor said for the drug's name, and that the doctor tells them the record has been corrected. The AI product, the medication and the summary are not public, and the doctor's own account is known only through the patient.

Aug 2026ChinaUnidentified symptom-analysis tool
A Guangming Daily feature on AI symptom-checking, republished by Bingtuan Daily on Sina Finance on 8 October 2026, recounts a case from August 2026 in Zhejiang and closes it with a quotation from the head of paediatrics at a provincial hospital, who says the family did not heed the doctor's advice. A three-year-old boy with a history of asthma was brought in; his mother had entered keywords such as allergy, asthma, cough and night-time wheezing into an AI tool, which quickly returned a diagnosis of an acute bronchial asthma attack. On that basis, the account says, she declined the chest X-ray the doctor recommended and insisted on taking home only nebuliser medication. Two days later the child's condition worsened with rapid breathing; on an overnight return to the hospital, examination found extensive inflammatory lesions in both lungs, and he was diagnosed with human metapneumovirus pneumonia with a superimposed bacterial infection and admitted as an emergency. The paediatrics head is quoted saying the illness would not have become so severe had the family listened earlier. The AI tool is not named. The case is told in the newspaper's voice, and the feature does not say where its account came from beyond the paediatrics head's quotation; no statement from the family is reported.

2 Oct 2026United StatesUnidentified AI phone ordering system
In a public post to r/legaladvice created early on 6 October 2026 (UTC), a person who gives their location as Colorado, United States, writes that their insurer moved their prescription to the specialty pharmacy Accredo. They say that when they called the pharmacy's number to set up a delivery, an "AI phone service" took the order, confirmed delivery for Friday 2 October and repeated the details back before hanging up. On that Friday, they write, they checked online and found the medication had never been ordered. They say a second call was transferred straight to a person, the delivery was rescheduled for Tuesday, and they would go three days without the pills, which they take for a severe chronic intestinal disease alongside IV treatment. They say their doctor was consulted and does not like the gap. The poster also says part of the problem was their own late ordering. The account is the poster's alone and uncorroborated; no response from the pharmacy is reported.
