The cost-effectiveness of candesartan-based antihypertensive treatment for the prevention of nonfatal stroke: results from the Study on COgnition and Prognosis in the Elderly.

Abstract

Patients who survive a first stroke are often left with permanent disabilities, and have significant needs for rehabilitation and long-term care. Antihypertensive treatment reduces the risk of cardiovascular events such as stroke. The purpose of this study was to investigate the cost-effectiveness of candesartan-based antihypertensive treatment for the prevention of nonfatal stroke. The cost-effectiveness analysis was based on data from Study on COgnition and Prognosis in the Elderly (SCOPE), where patients were randomly assigned to receive the angiotensin receptor blocker candesartan or placebo, with open-label active antihypertensive treatment added as needed. The analysis was carried out using a Markov model, which combined clinical and resource utilization data from SCOPE with Swedish retail prices for drugs and unit costs for in-patient stays, and outpatient visits. The cost per patient was 1949 EUR in the candesartan group and 1578 EUR in the control group. The largest share of the cost was attributed to antihypertensive treatment in the candesartan group and to the long-term cost of stroke in the control group. Candesartan-based antihypertensive treatment was associated with 0.0289 additional quality-adjusted life-years (QALYs) per patient and an incremental cost per QALY gained of approximately 13,000 EUR. Sensitivity analyses showed that these results were fairly stable. In conclusion, the cost per QALY gained with candesartan-based antihypertensive treatment lies within the range of society's willingness to pay for health gains. The results indicate that candesartan-based antihypertensive treatment is cost-effective for the prevention of nonfatal stroke.
