Improving blood pressure control in general practice: A pilot study of the ImPress intervention

Patients with hypertension and at high absolute cardiovascular disease risk are a priority group for improved blood pressure control. This study examined the impact of an intervention, primarily delivered by the general practice nurse, to identify, recall and manage patients with uncontrolled hypertension who are at high risk of cardiovascular disease.

A before-and-after pilot study with a six-month follow-up period was conducted in eight general practices in Sydney, Australia.

From 507 patients identified, 82 (16.2%) attended an assessment visit, were eligible and provided baseline data. Of these, 55 (67.1%) completed the six-month follow-up. The mean decrease in blood pressure was 14.5 mmHg systolic and 7 mmHg diastolic. Significant decreases were also found in mean weight (1.3 kg), body mass index (0.5 kg/m">22) and waist circumference (1.9 cm). Adherence to blood pressure treatment, as measured by the Hill-Bone scale, significantly improved (P = 0.01) DISCUSSION: The results of this study justify further investigation in a randomised trial. If effective, the approach could alter the way hypertension care is organised and delivered in Australian general practice.
