A new study led by investigators from Mass General Brigham has found that ChatGPT was about 72% accurate in overall clinical decision making, from coming up with possible diagnoses to making final diagnoses and care management decisions.
. But the capacity of LLMs to assist in the full scope of clinical care has not yet been studied.
The study was done by pasting successive portions of 36 standardized, published clinical vignettes into ChatGPT. The tool first was asked to come up with a set of possible, or differential, diagnoses based on the patient's initial information, which included age, gender, symptoms, and whether the case was an emergency.
The team compared ChatGPT's accuracy on differential diagnosis, diagnostic testing, final diagnosis, and management in a structured blinded process, awarding points for correct answers and using linear regressions to assess the relationship between ChatGPT's performance and the vignette's demographic information.
The authors note that before tools like ChatGPT can be considered for integration into clinical care, more benchmark research and regulatory guidance is needed. Next, Succi's team is looking at whether AI tools can improve patient care and outcomes in hospitals' resource-constrained areas.
