<H3>Special Instructions</H3><p> <p>There is the need for at least 3 partners for this test. Thus is this strongly suggested to use the central archive as one of the sources.</p> <p> Here we test the ARI Option Multiple Sources. Do not run the test if you do not support that option.</p> </p><H3>Description</H3><p>In order to claim support for this profile option, an Report Reader shall be able to query and retrieve from multiple Report Repositories.</p><p>There is no requirement as to whether the multiple queries or retrieves are done concurrently or sequentially.</p><p>Report Readers  shall have the ability to be configured to access multiple Report Repositories  (respectively).</p><p> Report Repositories shall also support the Patient Information Reconciliation integration profile in order to ensure that the information gathered from them is as accurate as possible.    Since having actors in different ADT (patient identifier) domains could result in unpredictable query results, this option assumes that all actors are members of the same ADT domain (i.e., it can be assumed that a given patient identifier uniquely refers to a single patient).</p><p>A Report Reader  supporting this profile option may be configured to initially query only its local information source; however, it shall be possible to query multiple sources with a single user request.</p><H3>Evaluation</H3><p>When an Image Display and Report Reader are combined, a single user request shall suffice to trigger a query of multiple sources for both images (and anything else stored in an Image Manager/Image Archive) and reports.</p><p>    If communication with an information source fails, an Image Display shall provide the information it received from the other sources. In addition, the Image Display  shall inform the user that they are viewing potentially incomplete results.   </p><p>When an Image Display  performs a study-level or series-level query to multiple sources and finds the study/series referenced in multiple places, the study/series is either duplicated or the study/series is split across the systems. When the user requests a retrieval of the study/series an Image Display  shall collate the information, determine if the information is actually duplicated or split, and present to the user a consolidated view of results.     The consolidated view of results may be shown and updated either as responses are received or when the final response has been received from the last responding information source.</p><p>A participating Image Display  shall manage duplicate instances in a manner that avoids redundant retrieval.</p>
