Exclusion element guidance:

The intent for the exclusion for patients who are clinical trial participants was to be limited to patients participating in a clinical trial for acute myocardial infarction (AMI), ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (non-STEMI), heart attack, or acute coronary syndrome (ACS), the same conditions as covered by the measure. However, the value set specifying clinical trial participation is not limited to a specific type of trial.

Medical or patient reasons for not performing a test or giving a medication are categories for valid medical or patient reasons that are not specifically listed in the exclusion section of the measure. Each is expected to be captured and made available for measurement or clinical decision support within the EHR workflow but the exact method or location of capture is a local or vendor decision.
