Retrieval-Augmented Multimodal Language Model with Heterogeneous Evidence Integration for Clinical Prognosis
TL;DR
PRISM, a novel multimodal language model, integrates diverse clinical data for prognosis, achieving high AUROC scores across various tasks, including diagnosis and mortality prediction.
✦ Why It Matters
Consider implementing PRISM's retrieval methods to enhance your clinical prediction models today.
Key Takeaways
- Explore PRISM for integrating diverse clinical data types.
- Utilize mean-pooled embeddings for improved predictive accuracy.
- Implement recency-weighted aggregation for ECG data.
- Consider supervised fine-tuning on external cohorts for better performance.
How It Works
PRISM combines various data types by tokenizing numerical features and aggregating ECG waveforms based on recency. It retrieves embeddings from similar patient encounters rather than individual records, allowing for a more generalized and effective prediction model.
