<H3>Special Instructions</H3><p> <p>Importer actors which support the Unscheduled Import option must run this test.</p> <p>Prior to this test, the Patient Demographics Supplier actor must first complete test PDQ_Load.</p> </p><H3>Description</H3><p>This test verifies the ability of the Patient Demographic Supplier and Importer to exchange Patient Demographic Query transaction. (ITI TF-2:2.4.21 and RAD TF-3:4.59.4.1.2.3.1). </p><p>The Importer must support either Patient-Based Query, Broad  Query, or both.</p><p>In the Patient Based Query, an Importer should support all  combinations of: Patient Name (0010,0010), Patient ID (0010,0020), Accession  Number (0008,0050), Requested Procedure ID (0040,1001).</p><p>In the Broad Query, an Importer should support all  combinations of: SPS Start Date (0040,0002), Importer (0008,0060), Scheduled  Station AE Title (0040,0001). </p><H3>Evaluation</H3><p>Connectathon monitor should observe query in real time and evaluate response.</p><p>The semantics of the PDQ query are not defined by the Technical Framework. Some systems may return more than one record for this query. The purpose of the evaluation is to determine if a response is returned and if the behavior is reasonable.</p><p>For example, if the supplier always returns the entire database for any name search, that would not be a reasonable implementation. That would fail this test.</p>
