Abstract
AbstractImportanceMedicine is poised for transformation with artificial general intelligence becoming integral to almost all clinical environments. Currently, the performance of multimodal AI, specifically one powered by GPT-4, in real clinical cases remains uncharted.ObjectiveTo ascertain whether GPT-4V can consistently comprehend complex diagnostic scenarios through both imagery and textual data.DesignA selection of 140 clinical cases from the JAMA Clinical Challenge and 348 from the NEJM Image Challenge were used. Each case, comprising a clinical image and corresponding question, was processed by GPT-4V, and responses were documented. The significance of imaging information was assessed by comparing GPT-4V’s performance with that of four other leading-edge large language models (LLMs).Main Outcomes and MeasuresThe accuracy of responses was gauged by juxtaposing the model’s answers with the established ground truths of the challenges. The confidence interval for the model’s performance was calculated using bootstrapping methods. Additionally, human performance on the NEJM Image Challenge was chronicled, reflected by the choice percentage selected by challenge participants.ResultsGPT-4V demonstrated superior accuracy in analyses of both sources, achieving 73.3% for JAMA and 88.7% for NEJM, notably outperforming text- only LLMs such as GPT-4, GPT-3.5, Llama2, and Med-42. Remarkably, both GPT-4V and GPT-4 exceeded average human participants’ performance at all complexity levels within the NEJM Image Challenge.Conclusions and RelevanceGPT-4V has exhibited considerable promise in clinical diagnostic tasks, surpassing the capabilities of its predecessors as well as those of human experts. However, while its proficiency in identification tasks is commendable, it requires further refinement in decision-making and strategic planning. Despite these encouraging results, such models should be adopted with prudence in clinical settings, serving to augment rather than replace human discretion. Continual research is imperative to fully evaluate the potential impact on patient care.
