Lowering blood pressure in primary care in Vienna (LOW-BP-VIENNA) : A cluster-randomized trial.

In both groups statistically and clinically significant BP reductions were observed after 6 months. In the interventional care group, a larger proportion of patients achieved the office BP target compared to standard care. The 24 h ambulatory blood pressure levels were controlled in 44% of patients at 6 months, without significant differences between groups. The respective BP reductions were achieved with a significantly lower medication burden in interventional care.
