This study introduces a novel system for identifying and removing personal health information from patient records. The system achieves 98-99% accuracy in detecting personally-identifying information using advanced natural language processing tools.

Area of Science:

  • Medical Informatics
  • Natural Language Processing
  • Data Privacy

Background:

  • Patient records contain sensitive personally-identifying information (PII).
  • Anonymization is crucial for protecting patient privacy and complying with regulations.
  • Existing methods for PII removal may lack comprehensive accuracy.

Purpose of the Study:

  • To develop and evaluate an original system for locating and removing PII from patient records.
  • To demonstrate that anonymization can be framed as a knowledge extraction task.
  • To leverage advanced natural language processing (NLP) tools for enhanced PII detection.

Main Methods:

  • Utilized the MEDTAG framework, including a specialized medical semantic lexicon.
  • Employed word-sense and morpho-syntactic tagging tools for text analysis.

Related Experiment Videos

  • Developed a novel system integrating these NLP components for PII identification.

    • Main Results:

    • The developed system accurately identifies and locates PII in patient records.
    • Achieved a high detection rate of 98-99% for all personally-identifying information.
    • Demonstrated the effectiveness of NLP techniques in medical data anonymization.

    Conclusions:

    • The presented system offers a highly effective solution for anonymizing patient records.
    • This approach significantly enhances the protection of sensitive patient data.
    • The system's high accuracy supports its application in real-world healthcare settings.
