<H3>Special Instructions</H3>  <p>Patient Identifier Cross-reference Consumer actors which support the <b>PIX Update Notification</b>    option must run one instance of this test.</p> <p>PIX Managers also run this test.</p> <p>Both the HIMSS Registration Tool and a vendor's Patient Identity Source actor is needed to help with this test.  The Patient Identity Source is marked as 'optional' in this test because it has no functionality which is evaluated; it is just helping with the test.</p>   <H3>Description</H3>  <p>This test ensures that the Patient Identifier Cross-reference Manager notifies the Patient    Identifier Cross-reference Consumer using ITI-10, when there is a change in a set of    cross-reference patient identifiers belonging to Patient Identifiers in the "Domains of    Interest" to the PIX Consumer.  This test is based on the scenario in ITI TF-2:3.10.4.1.2.</p>   <p>In order for this test to work, the PIX Manager must configure the "Domain of    Interest" to this PIX Consumer to be the value of the Assigning Authority for the    Patient Identity Source actor in this test as well as the Assigning Authority of the HIMSS Registration Tool.  The ability to do this configuration is    evaluated in test PIX_Mgr_Configuration.</p>  <H3>Evaluation</H3>  <p>The connectathon monitor should observe evidence that the PIX Consumer is receiving messages from the PIX Manager when patients are admitted or updated in the 'domains of interest' configured for that Consumer on the PIX Manager.  This can be done by examining the messages in the chat window (if they were captured by the participants in this test).  The connectathon monitor may also ask to see a new patient registered and/or updates on either the Patient Identity Source or the HIMSS Registration Tool and watch the notifications come in real-time.  </p>
