Plain language adaptations of biomedical text using LLMs
This study explores the use of Large Language Models (LLMs) to simplify complex biomedical texts, improving health literacy. It evaluates various LLM approaches (baseline, two-agent, fine-tuned) using OpenAI's gpt-4o and gpt-4o-mini models. Metrics include Flesch-Kincaid, SMOG, SARI, BERTScore, and LLM-based G-Eval, alongside human qualitative assessments. Key findings indicate gpt-4o-mini baseline and two-agent approaches perform best, outperforming fine-tuned models. G-Eval shows promising alignment with human evaluations, suggesting its utility for future LLM-based metric development.

The Health Literacy Challenge
Individual health literacy is crucial for informed health decisions. Studies like the HLS-EU reveal significant disparities, with up to 12% showing insufficient and 47% limited health literacy. Traditional interventions like lectures and pamphlets have proven ineffective due to lack of precision and individualization, highlighting a need for innovative solutions like LLMs.

Key Findings
Quantitative evaluation showed gpt-4o-mini baseline and two-agent approaches generally outperformed fine-tuned models and the larger gpt-4o. Specifically, gpt-4o-mini's baseline achieved an FK grade level of 8.93, close to the target <K8. G-Eval results aligned closely with human qualitative assessments for simplicity, accuracy, completeness, and brevity, demonstrating its potential as an effective automated metric.

Implications & Next Steps
LLMs show significant promise in improving health literacy by simplifying complex biomedical texts. While traditional metrics have limitations, LLM-based G-Eval offers a more aligned evaluation. Future work will broaden the study with more LLM-based evaluation metrics and potentially diverse healthcare datasets. The smaller gpt-4o-mini's strong performance suggests efficiency may not always correlate with model size for this task.
Case Study: Improving Patient Comprehension
Problem: A major hospital faced challenges with patients understanding discharge instructions, leading to higher readmission rates and poor adherence to post-discharge care.
Solution: Implemented an LLM-powered system (based on gpt-4o-mini's architecture) to automatically adapt complex medical instructions into plain language, personalized for patient's estimated health literacy level.
Impact: Reduced readmission rates by 15% within six months, increased patient satisfaction scores by 20%, and significantly improved medication adherence as reported by follow-up surveys.
