A physician-pharmacist model for the surveillance of blood pressure in the community: a feasibility study

Hypertension is poorly managed. Hospital-based pharmacists working with physicians have been shown to improve the rate of achievement of 'target' blood pressure in selected patients. It is unknown if such schemes can operate in the community and to what extent they would attract volunteers with poorly managed blood pressure. We assessed the feasibility of pharmacists to provide community-based, open-access, blood pressure monitoring. In addition, we describe the blood pressure profile of the group in comparison to that of the 1994 Health Survey of England (HSE). Pharmacists from six pharmacies were trained to deliver the service. Adults living within the postal districts of the pharmacies were invited, through an advertising campaign, to volunteer to have their blood pressure measured. Blood pressure data and information on treatment for hypertension and/or diabetes were collected on 263 registrants. Patients were advised to have their blood pressure managed by the general practitioner immediately (category 1), re-measured within 2-3 months (category 2) or in 12 months time (category 3). The mean (s.d.) blood pressure of patients in categories 1 (n = 16), 2 (n = 117) and 3 (n = 130) was 186(16)/97(29), 151(13)/94(9) and 139(22)/86(13) mm Hg respectively; P < 0.001. Ninety-one patients (35%) were in receipt of anti hypertensive therapy. Forty-five percent of the treated group had controlled blood pressure (< 160/95 mm Hg) compared with 30% in the HSE dataset. A large proportion of known hypertensive patients with poor blood pressure control who had visited their general practitioner within the previous 6 months were detected by the pharmacist-led service. Pharmacists operating an open-access blood pressure monitoring service may be of value in improving the management of hypertension.
