Qualitative metrics from the biomedical literature for evaluating large language models in clinical decision-making: a narrative review

The most frequently used criteria for defining high-quality LLMs have been consistently selected by researchers over the past 1.5 years. We identified a high degree of variation in how studies reported their findings and assessed LLM performance. Standardized reporting of qualitative evaluation metrics that assess the quality of LLM outputs can be developed to facilitate research studies on LLMs in healthcare.
