Clinical implementation of the IHE presentation of grouped procedures integration profile in a multivendor environment--workflow modification and barriers to implementation.

The implementation of presentation of grouped procedures (PGP) integration profile, as described in the Integrating the Healthcare Enterprise (IHE) Technical Framework, on computed tomography (CT) and magnetic resonance (MR) scanners as well as the picture archiving communication system (PACS) addresses the problem faced by many institutions in which there are multiple-requested procedures performed in one acquisition. It is a solution that, just like the initial implementation of PACS, requires substantial modification to workflow. Implementation of PGP not only speeds access to relevant images for the requested procedure, it reduces network traffic and is less demanding on workstation hardware because of the smaller data sets transmitted.
