This study introduces a method to improve the safety and standardization of free-text data annotation and sharing in electronic health records (EHRs). This approach enhances data reusability for research while protecting sensitive information.
Area of Science:
- Health Informatics
- Data Science
- Medical Record Management
Background:
- Electronic health records (EHRs) offer valuable data for retrospective studies.
- Free-text fields in EHRs pose challenges for data availability, reusability, and sharing.
- Credentialed data within free-text limits secondary use and data sharing.
Purpose of the Study:
- To propose a novel method for guiding the annotation of EHRs free-text data.
- To enhance the standardization of free-text data sharing procedures.
- To improve data safety and facilitate secondary use of EHRs data.
Main Methods:
- Development of a standardized annotation framework for EHRs free-text.
- Implementation of data safety protocols for information extraction.
- Establishment of procedures for secure data sharing.
Main Results:
- The proposed method facilitates structured data extraction from unstructured EHRs notes.
- Standardized annotation improves data consistency and quality for research.
- Enhanced data sharing protocols increase the potential for secondary data analysis.
Conclusions:
- A standardized approach to EHRs free-text annotation and sharing is crucial.
- The proposed method addresses data safety and procedural standardization challenges.
- This facilitates greater data reusability for clinical research and data science applications.
