PreRAID Dataset

Prescreening Rheumatoid Arthritis Information Database (PreRAID)
Developed by RespAI Lab at KIIT and KIMS Bhubaneswar.

---

Overview

PreRAID is a structured dataset designed to evaluate the diagnostic capabilities of Large Language Models (LLMs) in Rheumatoid Arthritis (RA) diagnosis. This dataset provides real-world patient data, offering insights into RA prediction and reasoning accuracy.

Data Description

• Total Records: 160 patient entries.
• Collection Location: KIMS Bhubaneswar, India.
• Demographic Breakdown:
  • Gender: 85% Female, 15% Male.
  • Diagnosis: 85% RA, 15% Non-RA.
• Languages Used: English and Odia.
• Data Collection: Through a structured online form supervised by RA medical professionals.

Key Information Captured

1. Demographic Details: Age, gender, language, and unique identifiers (e.g., KIMS ID).
2. Symptoms: Pain localization, onset duration, joint swelling, stiffness, and deformities.
3. Associated Conditions: Skin rashes, fever, ocular discomfort, and daily activity impacts.
4. Doctor-Verified Diagnoses: Ground truth and explanatory notes for RA and non-RA cases.

---

Dataset Features

1. Structured Patient Records: Standardized text representation for uniform analysis.
2. Visual Aids: Diagrams for precise pain localization.
3. Embedded Vectors: Text embeddings for semantic relationships using GPT-4 text embedding models.
4. Storage: Organized in a vector database to enable retrieval-augmented generation (RAG).

Research Insights

The dataset was utilized to investigate LLM misalignment in RA diagnosis. Key findings:

• LLMs achieved 95% accuracy in prediction but with 68% flawed reasoning.
• Misalignment between prediction accuracy and reasoning quality emphasizes the need for reliable explanations in clinical applications.

Usage

The PreRAID dataset is ideal for:

1. Diagnostic Analysis: Evaluating AI model accuracy and reasoning quality for RA.
2. RAG Applications: Utilizing vectorized patient records for enhanced model reasoning.
3. Healthcare AI Research: Studying interpretability and trustworthiness of LLMs in medical settings.
