ReToP: Learning to Rewrite Electronic Health Records for Clinical Prediction

ReToP is a novel LLM-based framework that enhances clinical prediction by learning to rewrite Electronic Health Records (EHRs) for improved accuracy. It addresses challenges like EHR sparsity and heterogeneity through an end-to-end training of an EHR rewriter and a clinical predictor. The framework generates synthetic pseudo-labels for training and uses a Classifier Supervised Contribution (CSC) score to align rewrites with prediction objectives. ReToP significantly outperforms state-of-the-art baselines across multiple clinical tasks on MIMIC-IV, eICU, and EFEMERIS datasets, demonstrating superior performance, especially for imbalanced tasks. Its generalizability to unseen data and tasks, while preserving faithfulness and emphasizing task-relevant features, positions ReToP as a promising tool for effective healthcare AI.

Case Study: MOR Task on MIMIC-IV

The qualitative analysis of ReToP on MIMIC-IV for MOR task reveals that the EHR rewriter (w/o KL) intrinsically outputs faithful rewrites. The KL alignment emphasizes predictive clinical features, which can be serendipitous but valuable for accurate prediction. For instance, while 'self-gen' rewrites can add unfaithful information, ReToP focuses on filtering task-relevant features, leading to better prediction. ReToP reduces diagnoses from 30 to 24 and laboratory tests from 51 to 34 while preserving faithfulness. This filtering approach highlights the model's ability to focus on highly predictive features, even if not immediately obvious to human experts, opening avenues for model explainability.

ReToP Implementation Roadmap

A phased approach to integrating ReToP into your existing healthcare AI infrastructure.

Phase 1: Data Integration & Baseline Setup

Establish secure data pipelines for EHR access and integrate ReToP's rewriter and predictor modules. Define target clinical prediction tasks and set up baseline models for comparative analysis.

Phase 2: Synthetic Data Generation & Fine-tuning

Leverage ReToP's pseudo-labeling strategy to generate synthetic EHR rewrites. Fine-tune the EHR rewriter using causal language modeling for initial task-agnostic improvement.

Phase 3: End-to-End Alignment & Validation

Implement the Classifier Supervised Contribution (CSC) score for end-to-end training. Align the rewriter with clinical prediction objectives using KL divergence and validate performance on unseen datasets.
