# The Lancet publishes Google–BIDMC real-world study of AMIE

Full title: The Lancet publishes Google–BIDMC real-world study of AMIE: 98 primary-care patients, no safety stops, 90% diagnosis match

On Oct 8, 2026 Google announced that its prospective study of AMIE, a research conversational diagnostic AI, at Beth Israel Deaconess Medical Center's ambulatory primary-care clinic was published in The Lancet, Google's first paper in the journal's main edition. 98 patients chatted with AMIE before urgent-care visits under real-time physician supervision. No conversation had to be stopped under the predefined safety criteria, AMIE's differential matched the doctors' final diagnosis about 90% of the time, and clinicians said its summaries helped them prepare in 75% of cases.

## Key facts
- Design: prospective, single-arm feasibility study; AMIE took the clinical history and presented possible diagnoses for patients to discuss at urgent-care appointments (preprint arXiv 2603.08448, March 2026)
- 98 patients; human safety supervisors watched every conversation in real time and did not need to stop any under the predefined criteria
- Clinicians: AI summaries helped them prepare for visits in 75% of cases and influenced their approach to care in more than half
- AMIE's differential diagnoses matched the doctors' final diagnoses ~90% of the time (Google blog)
- Patients reported high satisfaction; their attitudes toward AI improved after the interaction (p < 0.001, preprint abstract)
- Google calls it its first publication in the main journal of The Lancet; BIDMC billed it as the first real-world study of the safety and quality of patient-facing AI in primary care (Oct 9 release)

## What happened

Google and BIDMC ran AMIE (Articulate Medical Intelligence Explorer) with real patients before urgent-care appointments, with
physicians supervising each chat live. The peer-reviewed results appeared in The Lancet in October 2026, after a March preprint.

## Why it matters

Most medical-chatbot evidence comes from simulated patients or benchmarks. This is a prospective study with real patients that
reports safety (no interventions needed) and clinical usefulness. It is small, single-arm and supervised, so it shows feasibility,
not effectiveness against usual care.
