PACE-RAG: Patient-Aware Contextual and Evidence-Constrained RAG for Clinical Drug Recommendation

arXiv:2603.17356v2 Announce Type: replace Abstract: Drug recommendation requires a deep understanding of individual patient context, especially for complex conditions like Parkinson's disease. While LLMs possess broad medical knowledge, they fail to capture the subtle nuances of actual prescribing patterns. Existing RAG methods also struggle with these complexities because guideline-based retrieval remains too generic and similar-patient retrieval often replicates majority patterns without accounting for the unique clinical nuances of individual patients. To bridge this gap, we propose PACE-RA

Why this matters
Why now

The proliferation of broad medical knowledge in LLMs, coupled with their current limitations in nuanced patient-specific recommendations, creates an immediate need for advanced RAG techniques.

Why it’s important

Improving AI's ability to provide accurate and personalized drug recommendations has significant implications for healthcare efficiency, patient outcomes, and the broader application of AI in sensitive domains.

What changes

The development of patient-aware, contextually rich RAG models specifically designed for clinical drug recommendations represents a notable improvement over generic guideline-based or similar-patient retrieval methods.
