Paper: MEDIC: Towards a Comprehensive Framework for Evaluating LLMs in Clinical Applications (49 Pages)
Researchers from M42 Health, UAE are interested in holistic evaluation framework for healthcare. The authors argue that existing benchmarks, like the USMLE, while useful, do not fully reflect real-world performance.
Hmm..What’s the background?
MEDIC is designed to address limitations in existing LLM evaluations, which lack uniformity and do not sufficiently account for the multifaceted nature of healthcare applications. The following dimensions represent the key areas where LLMs need to demonstrate proficiency for safe and effective use in clinical settings: Medical Reasoning, Ethics and Bias, Data and Language Understanding, In-Context Learning, and Clinical Safety and Risk Assessment.
Ok, So what is proposed in the research paper?
The MEDIC benchmark tasks are designed to assess LLM performance across the five dimensions of clinical competence. They include a range of activities like answering closed and open-ended questions, summarizing medical texts, and generating clinical notes. Examples of these tasks include using multiple-choice questions to evaluate an LLM's breadth of medical knowledge and using open-ended questions to assess an LLM's ability to avoid answering questions where a response could negatively impact a patient.
The MEDIC framework utilizes a variety of datasets to evaluate LLMs across different clinical scenarios and tasks. These datasets contain various types of medical data, including medical exam questions, clinical trial descriptions, patient-doctor dialogues, and progress notes.
What’s next?
The authors acknowledge that using LLM-based judges, while efficient, can introduce biases into the evaluation process. For example, an LLM judge might favor responses similar to its own training data, potentially overlooking other valid responses. This limitation is exacerbated by the current lack of specialized medical LLM judges. The authors suggest that future work should focus on:
Incorporating more diverse datasets to train LLM judges and mitigate biases.
Increasing the involvement of expert clinicians in the evaluation process to provide nuanced judgment and insights that LLM judges might miss.
Refining evaluation metrics to better capture the complexities of clinical language and decision-making.
