**NQF-ENDORSED VOLUNTARY CONSENSUS STANDARDS FOR HOSPITAL CARE**Measure Information Form
Measure Set: Acute Myocardial Infarction(AMI)
Set Measure ID: AMI-6
Performance Measure Name: Beta-Blocker at Arrival
Description: Acute myocardial infarction (AMI) patients without beta-blocker contraindications who received a beta-blocker within 24 hours after hospital arrival
Rationale: The early use of beta-blockers in patients with acute myocardial infarction reduces mortality and morbidity (ISIS-1, 1986; Goldstein, 1996; and MIAMI, 1985) and has demonstrated effectiveness in a wide range of AMI patients (Krumholz, 1998). National guidelines strongly recommend early beta-blockers for patients hospitalized with AMI (Antman, 2004). Despite these recommendations, beta-blockers remain under-utilized in eligible older patients hospitalized with AMI (Jencks, 2000).
Type of Measure: Process
Improvement Noted As: Increase in the rate
Numerator Statement: AMI patients who received a beta-blocker within 24 hours after hospital arrival
Included Populations: Not applicable
Excluded Populations: None

- Patients who left against medical advice or discontinued care on day of or day after arrival
- Patients who expired on day of or day after arrival
- Patients discharged/transferred to a federal health care facility on day of or day after arrival
- Patients with one or more of the following beta-blocker contraindications/reasons for not prescribing beta-blocker documented in the medical record:
- Beta-blocker allergy
- Bradycardia (heart rate less than 60 bpm) on arrival or within 24 hours after arrival while not on a beta-blocker
