XDSI

XDSI is an acronym used in several technical contexts. In health information technology, it most commonly denotes Cross-Enterprise Document Sharing for Imaging, often written XDS-I. XDS-I is an IHE profile that enables secure exchange of medical imaging documents across healthcare organizations using the Cross-Enterprise Document Sharing (XDS) framework.

The goal is to allow clinicians to locate and retrieve imaging studies and related reports from external repositories without duplicating studies. Implementation typically involves IHE XDS components such as a Document Registry, Document Repository, and Registry services, plus Imaging Document Source and Imaging Document Consumer roles. Imaging data is referenced by metadata and may include DICOM objects; retrieval and presentation use standard web services and the XDS metadata model. Interactions are governed by patient identifiers, study metadata, and enterprise access controls, with privacy and security policies applying.

Benefits include improved continuity of care, reduced exposure to unnecessary imaging, and more efficient sharing of radiology information. Limitations include the need for interoperable systems, consistent metadata, robust identity management, and strong governance of consent and access. Network reliability, auditing, and data-transfer security are important considerations.

Other uses: Although XDSI is best known for imaging sharing, the acronym can appear in other contexts or organization names; the intended meaning should be inferred from accompanying definitions in each case.
