Enterprise AI Analysis
Uncertainty-aware large language models for explainable disease diagnosis
Explainable disease diagnosis, which leverages patient information (e.g., symptoms) and computational models to generate probable diagnoses and reasoning, holds strong clinical promise. Yet, when clinical notes lack sufficient evidence for a definitive diagnosis, such as the absence of definitive symptoms, diagnostic uncertainty commonly arises, increasing the risk of misdiagnosis. Despite its importance, the explicit identification and explanation of diagnostic uncertainty remain under-explored in artificial intelligence-driven systems.

Enhanced Diagnostic Precision
ConfiDx significantly improved diagnostic accuracy and uncertainty recognition compared to off-the-shelf LLMs, achieving accuracy gains over 68% and superior uncertainty recognition scores. This indicates its robust ability to identify when a definitive diagnosis cannot be made due to insufficient evidence.
Transparent & Reliable Explanations
The fine-tuned ConfiDx models provided more reliable and comprehensive explanations for both diagnoses and identified uncertainties, as evidenced by substantial improvements in interpretation accuracy and BERTScore over baseline models. This enhances clinician trust and understanding of AI's reasoning.
Consistent Performance Across Varied Data
ConfiDx demonstrated strong performance on unseen disease types (MIMIC-U) and generalized well across different institutions (UMN-CDR), showing its ability to internalize medical knowledge from diagnostic criteria and adapt to diverse clinical note styles. It also outperformed large-scale commercial LLMs in uncertainty recognition.
Empowering Clinical Decision-Making
When medical experts were assisted by ConfiDx, they significantly improved their performance in uncertainty recognition (10.7% gain) and explanation (26% gain) compared to working independently. This highlights ConfiDx's potential as a valuable tool for enhancing clinical decision-making and reducing misdiagnosis risks.

ConfiDx in Action: Acute Liver Failure Diagnosis
An off-the-shelf LLaMA model incorrectly diagnosed 'Severe metabolic acidosis' and failed to recognize diagnostic uncertainty. In contrast, ConfiDx correctly identified 'Acute liver failure' and recognized uncertainty due to the unmet criterion of 'no prior history of cirrhosis'.
Key Learning: ConfiDx successfully navigates complex cases, providing correct diagnoses and critical uncertainty explanations, preventing potential misdiagnosis compared to un-tuned LLMs.
