Most of the evidence is chatbots tested on written questions and small single-site studies; a few randomized trials and reviews carry more weight. TRV-2026-0355TRV-2026-1613TRV-2026-2032 Chatbots often match or beat doctors on structured written cases, while a 7294-patient trial of an AI alert in live care found no drop in delirium.

A randomized preclinical trial of 77 surgeons watching laparoscopic video shows AI assistance cut the time to find a bleeding site from 3.23 to 2.53 seconds on average. TRV-2026-2032 In a randomized crossover study, clinical trial staff using AI spent 2.71 fewer minutes per item reviewing charts for immunotherapy side effects, though severity grading was much weaker than event detection. TRV-2026-2318 Three randomized trials with over 90,000 US patients show that messages on personal high flu risk raised vaccination 1.7-3.5 percentage points over no message. TRV-2026-1852 A randomized trial of 130 final-year nursing students found AI-adaptive simulation raised leadership scores more than standard training, under controlled simulation conditions. TRV-2026-1262
In a test of 960 responses to clinician-written cases, ChatGPT Health undertriaged 52% of true emergencies, sending diabetic ketoacidosis and impending respiratory failure to 24-48 hour evaluation. TRV-2026-0181 A randomized trial of 7294 patients at Mount Sinai found an AI-triggered alert did not reduce delirium (35.1% vs 32.7%), though only 17.2% had a documented delirium assessment. TRV-2026-1664 In 16,254 responses to 29 standardized vignettes, all 21 chatbots failed differential diagnosis at rates above 0.80 even though final-diagnosis accuracy was high, a benchmark study found. TRV-2026-0145 A test of eight speech-to-text systems found at least one clinically significant error in 30% to 68% of 800 transcripts, and 39.6% of 53 errors with potential for severe harm involved medication type or dose. TRV-2026-1687
A review of 314 FDA-cleared surgical AI devices found only 5.1% had higher-quality prospective evidence. TRV-2026-1693 A scoping review of 1181 reports on AI decision tools found 62.7% stopped at clinical validation and 14.4% evaluated implementation or impact. TRV-2026-1613 A scoping review found only seven eligible studies of agentic AI in healthcare, with just one trial involving patients. TRV-2026-0166 A review of 310 publications found no study that measured AI's effect on critical thinking or clinical reasoning in medical education. TRV-2026-0458
Studies point in different directions on whether AI scribes ease clinician burnout. TRV-2026-0478TRV-2026-0330 An observational study of 263 clinicians in six US health systems reports that self-reported burnout fell from 51.9% to 38.8% after 30 days with an AI scribe. TRV-2026-0478 A systematic review of 6 real-world studies found clinicians reported less documentation time, but burnout on standardized scales was unaffected. TRV-2026-0330 At one cancer center, 190 of 958 clinicians used the AI scribe; after-hours time fell only from 86.9 to 81.4 minutes a week. TRV-2026-1819
Most tests find chatbot answers to patient questions accurate on average, yet poor readability and occasional unsafe answers recur. TRV-2026-1856TRV-2026-2452TRV-2026-1746TRV-2026-1715

A Trace is one record with both a gain and a problem, so it counts on both sides: 186 records show a gain and 188 show a problem. 128 context records are in the record list but not counted, because they report no measured gain or problem.

By type of evidence: 95 benchmark or lab tests; 43 observational studies; 42 controlled comparisons; 33 commentaries or narrative reviews; 29 surveys; 15 interview studies; 9 systematic reviews or meta-analyses; 9 randomized trials; 4 case reports; 3 investigations by reporters; 2 news reports; 2 regulatory or legal actions. How evidence is scored
In an online French study of 204 GPs and 942 patient histories, AI recorded histories more effectively than doctors, most clearly for older patients and for allergy and family cancer history.
In an observational study of 12,468 chronic disease patients in three Chinese provinces, AI-enabled care was linked to hypertension control targets met rising from 68% to 82%, with health data accuracy above 95%.
Clinicians using AI note-taking scribes in 6 real-world studies reported spending less time on documentation, though the evidence is sparse and based on self-reports.
A literature review linked AI decision support to vulnerabilities in doctors' physical examination, differential diagnosis, clinical judgment and patient communication skills, though magnitude and reversibility remain uncertain.
In 16,254 responses to 29 standardized clinical vignettes, all 21 AI chatbots tested failed differential diagnosis at rates above 0.80, even though final-diagnosis accuracy was high.
One review in this topic printed a pooled result: one figure calculated across many studies. They are the reviews’ own numbers, checked word for word against their abstracts. They often measure different things, so they are listed side by side, not added up.
