The methodological quality of included studies was variable. An organised system of regular review allied to vigorous antihypertensive drug therapy was shown to reduce blood pressure (weighted mean difference −8.2/−4.2mmHg, −11.7/−6.5mmHg, −10.6/−7.6mmHg for three strata of entry blood pressure) and all-cause mortality at 5 years follow-up (6.4% versus 7.8%, difference 1.4%) in a single large RCT (the Hypertension Detection and Follow-up study). Other interventions had variable effects. Self-monitoring was associated with moderate net reduction in diastolic blood pressure, weighted mean difference (WMD): −2.03 mmHg, 95% confidence interval (CI) = −2.7 to −1.4 mmHg. Educational interventions directed towards physicians were associated with small reductions in systolic blood pressure (WMD) −2.0mmHg, 95% CI = −3.5 to −0.6mmHg and diastolic blood pressure (WMD) −0.4mmHg, 95% CI −1.1 to 0.3mmHg.Conclusions General practices and community-based clinics need to have an organised system of regular follow-up and review of their hypertensive patients. Antihypertensive drug therapy should be implemented by means of a vigorous stepped care approach when patients do not reach target blood pressure levels. These findings have important implications for recommendations concerning implementation of structured delivery of care in hypertension guidelines. ER -
