De-identification of Brazilian Portuguese Clinical Records Using a Hybrid Pipeline with Local Language Models

2026-08-03

Abstract excerpt

<title>Abstract</title> <p> Secondary use of electronic health record narratives supports clinical research but requires removing personally identifiable information (PII). Processing identifiable records with external large language model (LLM) services raises critical privacy, governance, and data sovereignty concerns, necessitating locally deployable solutions. We propose and evaluate an offline, hybrid LLM p...
