UnverifiedDiagnostic accuracy does not equal clinical value; in real diagnosis and treatment, doctors also need to integrate unstructured information such as medical history, medication records, and patient communication, which is a shortcoming of current AI tools.73% similarUnverifiedExisting evaluation mechanisms systematically overestimate the quality of AI clinical medical records, primarily guarding against over-generation while almost never guarding against under-generation.73% similarUnverifiedThe study evaluated large models using real clinical cases rather than standardized exam questions in order to reflect the capability boundaries of models in practical applications.72% similar
