Abstract:

A major roadblock in the seamless digitization of medical records remains the lack of interoperability of existing records. Extracting relevant medical information required for further treatment planning or even research is a time consuming labour intensive task involving expenditure of valuable time of doctors. In this demo paper we present, MedPromptExtract an automated tool using a combination of semi supervised learning, large language models, natural language processing and prompt engineering to convert unstructured medical records to structured data which is amenable for further analysis.

Summary Notes

Introducing MedPromptExtract: A Game-Changer in Medical Data Extraction for AI Engineers

In healthcare, transforming unstructured medical records into structured, usable data is a major challenge, especially where data sharing between systems is limited. AI Engineers at enterprise companies are on a quest for efficient tools to make this conversion seamless and secure.

MedPromptExtract emerges as a state-of-the-art solution, automating this process with high precision and confidentiality. This blog post takes a closer look at MedPromptExtract, its methodologies, results, and its potential to revolutionize healthcare data management and research.

Streamlining Data Extraction and Anonymization

Background Innovations

• Automated Anonymization: Advances in machine learning have led to tools like the MITRE Identification Scrubber Toolkit, which protect patient privacy in electronic health records (EHRs).
• Structured Data Extraction: Previous efforts to extract data from EHRs have used NLP or SQL, facing challenges due to the variety of data management systems in healthcare.
• Unstructured Text Analysis: Utilizing large language models (LLMs) has been a breakthrough for extracting information from unstructured medical texts through methods like named entity recognition (NER).

How MedPromptExtract Works

MedPromptExtract's approach is detailed and multi-layered:

1. Dataset and Anonymization: It uses data from Kokilaben Dhirubhai Ambani Hospital, Mumbai, and the EIGEN model for anonymizing records, prioritizing confidentiality.
2. Extraction Techniques: It combines NLP techniques with prompt engineering through the Gemini API for precise extraction from both structured and unstructured texts.
