The week in brief¶

Clinicians are far less likely to reach a correct decision when automated advice is wrong, according to a systematic review of 46 reports that pooled an odds ratio of 10.19 across three adjusted cohorts [2]. In four real-world computerized electrocardiogram (ECG) studies, 26.6% of erroneous interpretations went uncorrected, leading the authors to argue that human oversight should be evaluated as an error-interception capability rather than assumed [2]. A public benchmark of 750 script concordance testing (SCT) questions points to a related risk: ten large language models (LLMs) matched or exceeded medical students on several examinations but fell short of senior residents and attending physicians, with reasoning-tuned models showing systematic overconfidence [5].

Evidence for LLMs as teaching tools remains preliminary. A meta-analysis of 14 studies found low-certainty signals for short-term knowledge and structured clinical performance, but no clear difference in delayed retention [1]. A podcast review of education research raised the possibility that Socratic AI tutors may reduce learning [13]. Simulation results were more consistent. A colposcopy virtual patient platform improved residents' case analysis and communication scores at one month, although operative competence did not differ [6]. In a separate pilot, AI standardized patients produced objective structured clinical examination (OSCE) gains similar to those from human actors, though that trial was not designed to demonstrate equivalence [3].

Guidance for students has not kept pace with this evidence. A review of 43 undergraduate studies found that 82% of students reported receiving no institutional guidance on LLM use [4].
