Unique Device Identification-Based Linkage of Hierarchically Accessible Data Domains in Prospective Surgical Hospital...

Area of Science:

• Biomedical Engineering
• Health Informatics
• Data Science

Background:

• Electronic Health Records (EHR) aim to systematize patient data but face challenges in cross-domain integration and access control.
• Interdisciplinary discourse is needed to address evolving medical technologies and unclear legal issues in data management.

Purpose of the Study:

• To address cross-domain data integration and access control using a unique device identification (UDI)-expanded hip implant example.
• To integrate technical data (UDI) into hospital information systems (HIS) and social data from mobile health (mHealth).

Main Methods:

• Additive manufacturing of a hip implant with integrated UDI.
• Development of a database with a wrapper layer, SQL database, and web API (REST API).
• Implementation of semantic integration for data element connections.

Main Results:

• Linked patient-specific imaging with a digital implant twin for improved surgical planning and implant-bone fit.
• Presented a UDI approach for postoperative data retrieval and future access.
• Developed concepts for monitoring patient-implant interaction via wearables and aggregating heterogeneous data sources.
• Demonstrated a hierarchical data access concept for sensitive patient data protection.

Conclusions:

• Personalized medicine necessitates cross-domain data linkage, requiring robust data infrastructure and hierarchical access solutions.
• Hip implants exemplify the value of cross-domain linkage, integrating social, medical, and technical aspects.
• Secure integration of data from end devices requires open databases with interfaces and suitable access models, ensuring long-term data persistence.
