English Abstract The effect of an intervention programme in general
practices was evaluated. The programme focussed, among other things, on
screening for hypertension and offering hypertensives non-pharmacological
treatment according to a standardized protocol. The change in blood
pressure over a span of one year in the intervention group (N=333) was
compared to that in control subjects from a monitoring project on
cardiovascular diseases (N=188). A significant larger mean decrease in
diastolic bloodpressure of 2.5 mm Hg was observed in the intervention
group. Although the measurement conditions were not totally alike for the
baseline and evaluation measurement a decrease of 2.5 mm Hg seems a
reasonable estimate of the effectiveness of the
programme.
