Abstract
PURPOSE
Arterial hypertension (AH) is associated with a high economic burden for the individual patient and for society in general. The study evaluates antihypertensives and their cost-effectiveness, comparing diuretics (D), beta-blockers (B), angiotensin converting enzyme inhibitors/angiotensin-II receptor blockers (A) and calcium channel blockers (C) with no intervention (NI).
METHODS
The study included five health states in a Markov model. Cost values included average cost of the drugs used, treatment in hospital and treatment in general practice (collected from Croatian Health Insurance Fund). The study was conducted separately for 65-year old men and women, with an initial probability of cardiovascular death risk of 2% and heart failure risk of 1%. The results were presented in terms of increase in QALYs and associated financial savings or costs in euros (€).
RESULTS
Results for men (compared with NI): treatment with D resulted in a QALY increase of 0.76 and €886 in savings, treatment with C in an increase of 0.74 QALYs and €767 in savings, treatment with A in an increase of 0.69 QALYs and €834 in savings, treatment with B resulted in an increase of 0.40 QALYs, but with an additional cost of €41. Results for women (compared with NI): treatment with D resulted in an increase of 0.93 QALYs and €987 in savings, treatment with C in an increase of 0.89 QALYs and savings of €855, treatment with A in an increase of 0.86 QALYs and savings of €991, treatment with B in an increase of 0.48 QALYs, but with an additional cost of €148.
CONCLUSIONS
Treatment of AH with D, C and A is cost effective compared with the no-intervention scenario. Diuretics are the most cost-effective first-line treatment. The scenario with beta-blockers resulted in additional QALY when compared with no intervention, but also additional costs; therefore, based on our results, this therapy would not be recommended as first-line treatment.
