Thank you for your question. In the December 2012 version of the eCQM specifications (CMS109v1 and CMS110v1), the initial population logic for these measures only checks for an active diagnosis of VTE, i.e. a patient is included in the IPP if they have an active diagnosis of VTE or obstetrics VTE. The denominator logic, however, covers multiple scenarios for the VTE diagnostic test that presumably originated the diagnosis. Specifically, the denominator logic allows for externally performed VTE diagnostic tests and results to support the VTE diagnosis. Please note that there are timing constraints associated with the date the VTE diagnostic test was performed, and these have been revised in the latest eCQM Release (April 2014); we encourage you to refer the eCQM specifications for the full context and detail of these criteria in the logic. In answer to your specific questions: # Can this test from another facility be utilized to input this patient in the eVTE population? Yes, a test from another facility can meet the denominator population criteria, per above explanation. # What can facilities do when encountered with this scenario? This scenario is explicitly handled in the denominator population logic, so as long as a facility can capture outside diagnostic tests, their associated results and date/time, and these meet the constraints in the denominator logic criteria, the case should be handled correctly by the eCQM denominator logic. # Should this case be in the Initial patient population? The case would be in the initial patient population if the DVT is included in the Venous Thromboembolism value set or the Obstetrics VTE value set (and also meets the remaining IPP criteria). The IPP logic, however, does not concern itself with the VTE diagnostic test or its results; these are covered in the denominator logic, per above explanation.
