Measure Set: Acute Myocardial Infarction(AMI)
Set Measure ID: AMI-2
Performance Measure Name: Aspirin Prescribed at Discharge
Description: Acute myocardial infarction (AMI) patients without aspirin contraindications who are prescribed aspirin at hospital discharge
Rationale: Aspirin therapy in patients who have suffered an acute myocardial infarction reduces the risk of adverse events and mortality. Studies have demonstrated that aspirin can reduce this risk by 20% (Antiplatelet Trialists' Collaboration, 1994). National guidelines strongly recommend long-term aspirin for the secondary prevention of subsequent cardiovascular events in eligible older patients discharged after AMI (Antman, 2004 and Smith, 2001). Despite these recommendations, aspirin remains under-utilized in eligible older patients discharged after AMI (Jencks, 2000).
