A VNA Supports Multiple Departments, Enterprise and Regional Architectures

A VNA Supports Multiple Departments, Enterprise and Regional Architectures

Centralizing storage management is much more cost-effective than doing it on a department level. The same advice applies for the physical storage. Having a computer room in radiology, cardiology and pathology does not make sense if there is already a very capable IT staff that has secure and reliable archive space available at the enterprise level.

One of the practical arguments from department managers and system administrators against having an archive supported by the IT department is that one has to relinquish control and does not have always full access and privileges to manage and maintain the system. A good compromise would be a separate room in an institution’s IT center that is accessible by both the IT and radiology support staff. In any case, enterprise-wide storage is a trend that will continue to evolve, and in many cases, regional archiving makes sense as well, especially for hospitals that are affiliated or owned by the same organization.

Critical for the support of multi-department support is the reconciliation of multiple patient identifiers via support for a Master Patient Index. Many traditional DICOM archives rely on unique accession numbers, which is something that cannot be guaranteed at the multi-department, enterprise, or regional level. Patient demographics can be reconciled using the PIX/PDQ capabilities as defined by the IHE.
