EHDS Challenge: Paradigm Shift from Data Interoperability to Utilization

Details

This article discusses implications for the Japanese healthcare IT industry based on the progress of the European Health Data Space (EHDS). It points out that while technical data linkage between various systems (like EHRs and applications) is advancing, a critical challenge remains in achieving 'Semantic Interoperability.' Simply moving data is not enough; it must be brought to a state where its clinical context can be understood and utilized. The proposed solution involves adopting an approach starting from existing systems (such as rapid transformation into FHIR) while crucially linking the 'meaning' of the data using reference terminologies like SNOMED CT. The ultimate goal is shifting perspective: value lies not in the volume of data, but in reducing the time required to read and utilize that data. The author argues that the framework set by EHDS represents only a 'possibility,' while the actual challenge lies in 'practicality' and 'cultural transformation.' It emphasizes the need for a shift in perspective—treating data not merely as an accumulated asset, but as 'readable, understandable, and actionable information.' This suggests that the required change involves not just technical aspects, but also operational practices and institutional awareness within healthcare facilities.
