Measure Set: Advanced Certification Heart Failure Outpatient(ACHFOP)
Set Measure ID: ACHFOP-03
Performance Measure Name: Hospital Outpatient Aldosterone Receptor Antagonists Prescribed for LVSD
Description: Aldosterone receptor antagonist therapy prescribed for heart failure patients with LVSD. For purposes of this measure, LVSD is defined as chart documentation of a left ventricular ejection fraction (LVEF) less than 40% or a narrative description of left ventricular systolic (LVS) function consistent with moderate or severe systolic dysfunction.
Rationale: Use of aldosterone receptor antagonist in eligible HF patients with LVSD and no documented contraindications, intolerance, or other medical reason(s) is recommended to reduce heart failure hospitalization and moratlity. Both ACEIs and ARBs can lower circulating aldosterone with initial therapy; however, aldosterone suppression may not be sustained over time. Clinical studies have demonstrated that the addition of spironolactone to ACEI therapy for patients wih NYHA class III or IV symptoms and recent hospitalization reduced the risk of death from 46% to 35% (30% relative risk reduction) over two years. Furthermore, a 35% reduction in heart failure hospitalization and improvement in functional class was noted. A more recent trial of a newer aldosterone antagonist, eplerenone, in patients with LVSD < 40% and clinical evidence of heart failure or diabetes mellitus within 14 days of myocardial infarction (MI) also demonstrated a reducation in mortality (13.6% to 11.8% at one year).
Hyperkalemia is a major risk of aldosterone antagonist therapy. Potassium supplements should be discontinued after the initiation of therapy, and patients should be counseled to avoid high-potassium foods.
Type of Measure: Process
Improvement Noted As: Increase in the rate
Risk Adjustment: No.
Data Collection Approach: Retrospective data sources for required data elements include administrative data and medical records.
Data Accuracy: Variation may exist in the assignment of ICD-10 codes; therefore, coding practices may require evaluation to ensure consistency.
Measure Analysis Suggestions: None.
Sampling: Yes. Please refer to the measure set specific sampling requirements and for additional information see the Population and Sampling Specifications section.
Data Reported As: Aggregate rate generated from count data reported as a proportion.
