Abstract:Large-language models have recently demonstrated impressive zero-shot capabilities in a variety of natural language tasks such as summarization, dialogue generation, and question-answering. Despite many promising applications in clinical medicine (e.g. medical record documentation, treatment guideline-lookup), adoption of these models in real-world settings has been largely limited by their tendency to generate factually incorrect and sometimes even toxic statements. In this paper we explore the ability of large-language models to facilitate and streamline medical guidelines and recommendation referencing: by enabling these model to access external point-of-care tools in response to physician queries, we demonstrate significantly improved factual grounding, helpfulness, and safety in a variety of clinical scenarios.
