The shared EHR (electronic health record) system architecture IHE XDS is widely adopted internationally. It ensures a high level of data privacy via distributed storage of EHR documents. Its standard search capabilities, however, are limited; it only allows a retrieval of complete documents by querying a restricted set of document metadata. Existing approaches that aim to extend XDS queries to document contents typically employ a central index of document contents. Hereby they undermine XDS' basic characteristic of distributed data storage. To avoid data privacy concerns, we propose querying EHR contents in XDS by indexing document types based on Archetypes instead. We successfully tested our approach within the ISO/EN 13606 standard.
共享电子健康记录（EHR）系统架构IHE XDS在国际上被广泛采用。它通过EHR文档的分布式存储确保了高度的数据隐私性。然而，其标准搜索功能有限；它只允许通过查询一组受限的文档元数据来检索完整文档。旨在将XDS查询扩展到文档内容的现有方法通常采用文档内容的中央索引。由此，它们破坏了XDS分布式数据存储的基本特性。为避免数据隐私问题，我们建议通过基于原型对文档类型进行索引来查询XDS中的EHR内容。我们在ISO/EN 13606标准内成功测试了我们的方法。
