<h3>Special Instructions</h3> Each Patient Identity Source needs to have an Assigning Authority assigned to that system for identifying that source. That Assigning Authority will consist of a text label and an OID. Do not proceed with this test without that value.  <H3>Description</H3>  <p>The purpose of the test is to feed the patient Identity Cross Reference Manager with patient information. Three patients will be identified. One patient will be the subject of PIX queries in later tests. The other two patients will be used to observe a merge operation.</p>  <p>We want to start with 3 patients. Two of the patients will be merged. This leaves one surviving patient from the merge and the last (original) patient. The orginal patient will be the subject of further tests.</p>  <p><b>Each source of patient identifiers is required to have their own assigning authority. Please contact the Project Manager if you do not have your own value. Using a common value will defeat later tests.</b> </p>  <p>We will use the Farnsworth patient for downstream query tests. After that patient is registered with the PIX manager, the operator of the Patient ID Source shall update the <a href="http://ihewiki.wustl.edu/wiki/index.php/Berlin-2007-Connectathon-PIX-Farnsworth"> Connectathon Wiki</a>  with details about the Patient ID and other information for Farnsworth. If the Patient Identity Source does not include a value for PID-3.4 (Assigning Authority),  then the Patient Identity Source system and the PIX Manager must agree that all messages from this source refer to a single Assigning Authority.  </p>  <p>Note : It is possible to perform the test simultaneously to an ADT_FILLER or an ADT_PLACER test if the ADT test supports also the actor Patient Information Source </p>   <h3>Evaluation</h3> <p>In order to verify the test the Connectathon monitor will  ask the following :</p> <ul>   <li>One of the two actors will have to show the HL7  message transmitted between the 2 actors</li>   <li>Show that the Patient Identity Cross Reference  Manager database content is taking into account the different messages from the  Source.     <ul>       <li>Patient FARNSWORTH,  STEVE exists with the value of Assigning Authority assigned to the Patient  Identity Source system in this test.</li>       <li>Patient TANNER,  CHARLES (not CHARLIE) exists with the value of Assigning Authority assigned to  the Patient Identy Source system in this test.</li>       <li>Patient  TANNER (not WALKER)  is the surviving patient after the merge. </li>     </ul>   </li> </ul> <p>'</p>
