Abstract

Background:
NICE guidelines are the accepted standard for determining the management of hypertension in UK primary care.

Aim:
To explore adherence and non-adherence to NICE hypertension guidelines, the extent to which this influences blood pressure control, and the role of ethnicity.
Design and setting:
A cross-sectional study was conducted based on primary care data from Lambeth DataNet, a database of primary care records in one inner-city London borough.

Method:
NICE guidelines were used to determine adherence to recommended treatment options for four groups of patients with hypertension: aged <55 years on monotherapy; aged ≥55 years on monotherapy; any age on dual therapy; any age and with comorbid diabetes. Blood pressure control was determined for each treatment category and ethnic group. The study controlled for age, sex, social deprivation, and clustering within general practices.

Results:
A total of 32 183 patients were identified with a current diagnosis of hypertension. Ethnic coding was available for 28 320 (88.0%). Overall, 13 546 patients with ethnicity coding could be allocated to one of the four clinical categories of hypertension; 44% of these patients received non-guideline-adherent treatment; ethnicity was not a significant determinant. Mean arterial pressure did not differ significantly between those receiving `correct' or `incorrect' hypotensive therapy.

Discussion:
Evidence-based guidelines for the management of hypertension were not followed in a relatively large proportion of patients included in this study. Nevertheless, no evidence was found that failure to follow treatment recommendations resulted in poorer blood pressure control. Further work is needed to determine the reasons for non-implementation of guideline recommendations in primary care.
