Identifying favorable-value cardiovascular health services.

OBJECTIVE

To identify cardiovascular health services with a high level of evidence to suggest that they deliver favorable value.

STUDY

DESIGN

Evidence synthesis using the Cost-Effectiveness Analysis Registry.

METHODS

We queried the registry to identify published cost-effectiveness analyses of cardiovascular health services in the United States. In addition to searching the registry, we performed supplementary searches of published literature for cost-effectiveness studies of cardiovascular interventions that were endorsed by guidelines of national medical and scientific societies. We defined favorable value as an incremental cost-effectiveness ratio of $100,000 or less per quality-adjusted life-year.

RESULTS

Our initial review of cardiovascular health services in the United States revealed 174 separate peer-reviewed studies. Of those, 157 studies did not meet our inclusion criteria, leaving 17 studies for further evaluation that covered the following services with potentially high value: statins to prevent myocardial infarction (for primary and secondary prevention), screening for and treatment of high blood pressure (diuretics or beta-blockers and angiotensin-converting enzyme inhibitors in the case of diabetes) to prevent myocardial infarction and stroke, warfarin sodium and low-molecular-weight heparin to prevent pulmonary emboli, implantable cardiac defibrillators for patients at high risk of sudden death, antiplatelet drugs (aspirin and clopidogrel bisulfate) to prevent future myocardial infarction, beta-blockers for patients who have had myocardial infarction, warfarin to prevent future stroke in persons with nonvalvular atrial fibrillation, and percutaneous procedures to relieve claudication symptoms.

CONCLUSION

We describe a new way of synthesizing cost-effectiveness evidence for use by consumers, payers, and other decision makers.
