We tested the performance of Chat Generative Pre-trained Transformer (ChatGPT) in the role of a trainee clinician (Specialist Registrar or Resident) undergoing direct assessment by a human supervising specialist clinician (Consultant or Attending). The session consisted of a hospital ward round scenario presented to three versions of ChatGPT, namely OpenAI ChatGPT-3.5, Bing ChatGPT-4 and OpenAI ChatGPT-4. A specific test of memory and context was included via an end-of-teaching educator feedback exercise. Only OpenAI ChatGPT-4 provided responses comparable to the standard a trainee might offer during progress towards completion of training and specialist accreditation. Bing ChatGPT-4 responded with several clinically dubious statements, often in a repetitive and detached way, and was unable to retain awareness of the purpose of the session and the identities of participants.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).
