A Google conversational AI held supervised pre-visit conversations with about 100 patients at a Boston hospital without a single safety stop, according to a prospective study The Lancet published Oct. 8.

Physicians supervised every conversation in the single-arm study, which Alphabet funded, the authors reported. A day earlier, Vanderbilt University Medical Center researchers reported in JAMA Psychiatry that 28 patients in its records had psychosis worsened by chatbot use, most of them in a first episode. The Centers for Medicare & Medicaid Services and the Centers for Disease Control and Prevention proposed letting pathologists review digital slides and images from outside the laboratory, and the University of Texas System opened Abridge's ambient documentation software to all of its health institutions.

Everlywell began selling a mammogram risk model authorized by the Food and Drug Administration directly to consumers, Suki added an UpToDate-based question tool to its scribe app, and Healthleap raised $38 million for hospital screening software, the companies said.

What is Physician in the Loop?

How technological innovation is changing medicine for patients and the people who practice on the front lines.

Voice 1: This is Physician in the Loop, the daily briefing on AI in medicine. It's Friday, October 9th, 2026.

Voice 1: In 98 supervised pre-visit conversations at Beth Israel Deaconess Medical Center in Boston, Google’s new conversational AI never triggered a single safety stop.

Voice 2: None at all? What actually counts as a stop?

Voice 1: The study doesn’t spell out the criteria beyond saying none of the conversations met them. Physician safety supervisors watched every chat live, and they still caught one hallucination and added clinical information in five of the sessions.

Voice 2: A hundred and fourteen patients signed up. Where did the other sixteen go?

Voice 1: The post doesn’t say. Only 98 completed both the chat and the actual visit, out of 114 enrolled between April and November last year. Patients talked with the AI, called Articulate Medical Intelligence Explorer or AMIE, up to five days before a single-complaint urgent primary care visit.

Voice 2: How did clinicians feel about reading the transcript before seeing the patient?

Voice 1: Primary care clinicians who read it ahead of time said it helped them prepare for the visit in 33 of 44 cases. Evaluators also rated the conversations favorably across 17 criteria, somewhere between 87% and 100%.

Voice 2: This is Alphabet-funded, and there’s no comparison group, right?

Voice 1: Right. It’s a single-arm study with no control arm, and Alphabet funded it. Google’s own summary of the preprint back in March said AMIE’s differential included the final diagnosis in 90% of cases and ranked it first in 56%, and that evaluators judged the physicians’ management plans more practical and cost effective. AMIE never touched the medical record and couldn’t examine anyone.

Voice 2: A day earlier, Vanderbilt looked at chatbots from the opposite direction. They found 28 patients in their own records whose psychosis got worse after using one.

Voice 1: Out of how many patients total?

Voice 2: They searched behavioral health notes from December 2022 through April this year, covering about 215,000 patients, and that’s where the 28 came from. Seventeen of them were in their first psychotic episode, significantly more than among patients with neutral chatbot use or AI-themed delusions with no documented chatbot use.

Voice 1: What chatbot are we actually talking about?

Voice 2: ChatGPT was named in 15 of the cases. Twenty-four of the interactions were documented after OpenAI released GPT-4o in May 2024, and the authors say that timing lines up with documented sycophancy in that model, though they’re careful to say the design can’t establish cause and effect.

Voice 1: Did the chatbot actually push people further into delusion, or just happen to be present?

Voice 2: In 18 of the cases, the authors say it amplified existing symptoms by validating distorted ideas. The median patient was about 28. The researchers flagged ascertainment bias, a single site and an unvalidated rating system as limits, but they wrote that routinely asking about AI use during psychiatric visits “appears warranted.”

Voice 1: Regulators also moved on something less dramatic but more concrete for pathologists.

Voice 2: What’s changing for them?

Voice 1: CMS and the CDC proposed a rule letting pathologists review digital slides and images from outside the lab, without needing a separate certificate for wherever they happen to be.

Voice 2: So a pathologist working from home would count as compliant?

Voice 1: That’s the idea. The lab director stays responsible for the testing, connections have to be secure, and labs have to log who reviewed remotely, on what device and with what software version. It would codify enforcement discretion CMS already started using back in 2023.

Voice 2: Does that cover cytology too?

Voice 1: No, virtual access wouldn’t be allowed there. But the rule would let labs run gynecologic cytology proficiency testing on digital images of glass slides instead of the slides themselves, citing FDA’s 2024 authorization of the first digital cytology screening system. Labs would also have to keep digital images alongside the cytology and histopathology slides.

Voice 2: The University of Texas System just opened Abridge’s ambient scribe to every institution it runs.

Voice 1: How big a system are we talking about?

Voice 2: Eight institutions are named in the announcement, including UT Southwestern, MD Anderson and UTHealth Houston. Each one decides for itself how to roll it out, under a systemwide framework signed October 8th.

Voice 1: What did the pilot leading up to this actually show?

Voice 2: It ran across five locations and more than 50 specialties, covering outpatient, inpatient and emergency settings. Over the past year, the number of clinicians recording encounters rose 73%, and monthly notes rose 80%.

Voice 1: That’s a system already handling a huge volume of care.

Voice 2: Nearly 12 million outpatient visits and more than 2 million hospital days in the past year, according to Becker’s. The deal was coordinated through a state-funded initiative called UT REAL Health AI, and it could later stretch into care gaps, payer workflows and trial matching.

Voice 1: Before we go, something to watch.

Voice 2: Utah just named who’s going to be checking its AI prescribing pilots. Six outside evaluators, including the Coalition for Health AI and Stanford, will inspect decision logs and outcomes. Nolla Health’s acne pilot now also requires monthly reports to the state, plus quarterly reports the state will make public.

Voice 1: So anyone outside Utah can actually see how these prescriptions are performing?

Voice 2: Only the quarterly versions, and only once the state posts them. Still, that’s more sunlight than most of these sandboxes get.
