Measuring benefits and costsof antihypertensive therapy
Would the actuarial, or observational, approach toevaluating the benefits and costs of antihypertensivetherapy prove'less fallible' and 'far-sighted', comparedwith the 'short-sighted' approach based on short-termintervention trials? This question has been raised byProfessor Alberto Zanchetti from the University ofMilan, Italy.
He cited the substantial differences that can occurwhen actuarial, instead of trial, data are used to calculatethe cost per life-year gained as a result of antihypertensive therapy. Using actuarial data, this cost is$US2000-$US5200 for men aged 35-55 years and$US3600-$US7900 for women aged 45-55 years- values which are much lower than those calculatedusing data based on meta-analyses of clinical trials.In addition, calculations based on actuarial data showthat treatment is more cost effective in younger thanin older patients, whereas calculations based on trialdata show the reverse to be the case.Zanchetti A.
