Cross-Community Access for Imaging

Summary

Cross-Community Access for Imaging(XCA) - Supports the means to query and retrieve patient relevant medical imaging data held by other communities.

The XCA-I Profile extends the IT Infrastructure XCA Profile. XCA provides access to all medical data including diagnostic reports and imaging manifests. XCA-I provides access to the images referenced in the imaging manifests.

Benefits

• Image access between Communities
• Common health information infrastructure with non-imaging data

Details

The Cross-Community Access for Imaging profile supports the means to query and retrieve patient relevant medical image data held by other communities. A community is defined as a coupling of facilities/enterprises that have agreed to work together using a common set of policies for the purpose of sharing clinical information via an established mechanism. Facilities/enterprises may host any type of healthcare application such as EHR, PHR, etc.

Such communities may be XDS Affinity Domains which define image sharing using the XDS-I profile. This profile addresses sharing between such communities.

The XCA-I Profile extends the IT Infrastructure XCA Profile for Imaging. XCA provides access to Diagnostic reports and Imaging Manifests. XCA-I provides access to the imaging objects referenced in the Manifests.

Systems Affected

Systems involved in this profile include:

• PACS or RIS systems may store, manage, and display imaging documents.
• EMR's and other patient management systems which will access and display imaging documents.
• HIE's, Image Exchange Systems, and VNA's which store, manage and display imaging documents for multiple systems.

Actors & Transactions:

The shaded actors are NOT included in this profile but are shown to illustrate the full set of actors that play a role other endpoint of transactions that ARE part of the profile (e.g., the Document Registry Actor is an endpoint for the Registry Stored Query Transaction).
