Partial cost-benefit analysis of two different modes of nonpharmacological control of hypertension in the community

Abstract

In the Dan and Ashkelon areas of Israel, 28 male and 24 female mild to moderate hypertensives without target organ damage aged 35-65 years were randomly assigned to treatment programmes (based on nutritional management, exercise and stress management techniques) either on an individual basis administered by physician-nurse teams (PN) or on a group basis from a team of paramedical professionals (PP) consisting of a psychologist, nutritionist and physical activity instructor. At 11 and 24 months follow-up, there were similar significant improvements in both treatment modes for such risk factors as body mass index, caloric intake and physical activity levels. There was a significant decrease in drug use from $36.28 a month at baseline to $18.94 a month at 11 month follow-up (P = 0.01) and to an estimated $20.48 at 24 months. Mean BP remained unchanged, despite the reduction in drug use, indicating a reduction in the underlying BP. The net present value (NPV) of the reduction in drug utilisation totalled $740 per person over a five year time horizon and a 7.5% discount rate. The total extra costs of treatment, training, case-note writing, travelling and follow-up booster sessions, amounted to $95 per patient for the PN mode and $234 per patient for the PP mode, yielding benefit to cost ratios of 7.79/1 and 3.16/l, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
