Economic Issues in the Treatment of BPH

The long-term cost of effective management for benign prostatic hyperplasia (BPH) remains an important issue in pharmacoeconomics because about 25% of men aged 50 yr and older experience voiding problems due to BPH. With the ageing population and the increase in the percentage of patients with BPH for whom any type of treatment can be considered, a substantial increase in total costs to society can be expected. The up-front costs of interventional approaches to BPH are being replaced by a pattern of long-term medical and preventive therapy. The age-adjusted rate of transurethral resection of the prostate (TURP) reached a high point in 1987 and TURP rates, but not costs, have been in decline ever since. Mean 1-yr treatment costs (medical therapy and TURP) have been estimated in a pan-European study to be 858 Euros per patient, 75% of which were medication costs. Using a 2-yr time frame for treatment, Medicare costs for finasteride, terazosin, and TURP have been estimated as $3874, $2161, and $1820, respectively. The available models of the total long-term cost for all therapies for BPH remain compromised by a lack of inclusion of indirect costs, the lack of true long-term data and, critically, the lack of human cost information (patient preference). Only medical therapy provides a preventive as well as symptomatic potential and, if all of the issues were fully incorporated, it is likely that medical therapy would be increasingly recognised as economically preferable.
