Thank you for your question regarding CMS104/STK-2: Discharged on Antithrombotic Therapy. The logic utilizes the "Medication, Discharge" datatype. When utilizing the "Medication, Discharge" datatype, the logic will look for the time stamp of a medication on a patient discharge medication list and is intended to express active medications ordered for post-discharge use The medication could be a previous antithrombotic the patient was already on or a newly prescribed medication during the encounter. The medication should be documented as a discharge medication on the discharge medication list with an author timestamp during the Ischemic Stroke Encounter.
