Abstract
Hypertension control is a difficult goal to achieve in common practice even when its benefits have been widely proved. We assessed the effectiveness of a Complex Antihypertensive Intervention Program in the Elderly (CAPE). A program trial of 500 elderly hypertensive patients was conducted. 250 were followed by primary care physicians and intervened by the CAPE and 250 received usual care. The program included an organizational change with the addition of an office where patients had their blood pressure measured, were appointed to join educational sessions and received verbal and printed advice before medical attendance. Data was systematically recorded in the electronic medical record which functioned as a physician reminder during the visit. Differences in systolic blood pressure level and in percentage of well-controlled (<140/90 mm Hg) patients between groups were measured after 12 months of follow-up. The difference of mean change in systolic blood pressure between groups was 7.1 mm Hg (95% confidence interval, 4–10 mm Hg). Sixty-seven percent of patients in the intervention group were well-controlled, as were 51% of patients in the control group (p <0.001). Patients who attended educational sessions showed the lowest odd ratio (0.25; 95% confidence interval, 0.11–0.54) for blood pressure above 140/90 mm Hg in multivariate analysis after adjusting for age, sex, initial systolic blood pressure level, and changes in antihypertensive treatment. These results support the effectiveness of our complex intervention program. Routine clinical care of hypertension can be improved with simple strategies that go beyond pharmacotherapy, tending to overcome clinical inertia. (Disease Management 2004;7:235–243)
