Abstract
A computer simulation model shows that the cost-effectiveness of treating hypertension is highly sensitive to different assumptions about the effectiveness of treatment, the outcome measure, the cost concept, the discounting of effects, and the duration of therapy. Cost-effectiveness analysis should be supplemented by another approach–cost-benefit analysis based on the contingent valuation (CV) method (the measurement, by survey, of willingness to pay). The CV method is tested in two empirical applications that indicate that it is possible to use the method in this area. Its results should be interpreted with caution, however, since the reliability and validity of the method is not yet established.
