Researchers have developed a new method using large language models (LLMs) to identify and recover protected health information (PHI) that traditional de-identification systems often miss. By employing institution-specific prompts, LLMs can better understand context-dependent PHI, such as hospital abbreviations and internal codes, which are crucial for accurate de-identification in electronic health records. This approach significantly outperformed existing systems in a study on pediatric oncology notes, achieving a recall rate of 0.981 and an F1 score of 0.907, while also offering a way to audit the reference standard for de-identification.
