Increases in antihypertensive prescriptions were associated with significant reductions in death from stroke, heart failure, and myocardial infarction (P<0.001 for all 3 diseases).

Do increases in antihypertensive prescriptions reduce hospitalization and death from major hypertension-related cardiovascular diseases in the general population aged >=20 years?
A national professional education program for hypertension management was associated with increased antihypertensive prescribing and significant reductions in cardiovascular mortality and hospitalizations.
p-value: p=<0.001
The Canadian Hypertension Education Program, an extensive professional education program to improve the management of hypertension, was started in 1999. There were very large increases in diagnosis and treatment of hypertension in the first 4 years after initiation of the program. The purpose of this study was to examine the association between the changes in antihypertensive therapy with changes in hospitalization and death from major hypertension-related cardiovascular diseases in Canada between 1992 and 2003. Using various national databases, Canadian standardized yearly mortality and hospitalization rates per 1000 for stroke, heart failure, and acute myocardial infarction were calculated for individuals aged >or=20 years and regressed against antihypertensive prescription rates. Changes in rates were examined in a time series analysis. There were significant reductions (P<0.0001) in the rate of death from stroke, heart failure, and myocardial infarction starting in 1999. There was also a reduction in hospitalization rate from stroke (P<0.0001) and heart failure (P<0.0001) but not myocardial infarction in 1999. The changes in death (P<0.001 for all 3 diseases) and hospitalization (P<0.0001 for stroke and heart failure; P=0.018 for acute myocardial infarction) were associated with the increases in antihypertensive prescriptions. This study demonstrates that the reduction in cardiovascular death and hospitalization rates is associated with an increase in antihypertensive prescriptions and that it coincides with the introduction of the Canadian Hypertension Education Program. The Canadian Hypertension Education Program educational model for improving health care could be adopted by other countries with well-developed professional and scientific societies.
Campbell et al. (2008) conducted an observational in Hypertension. Canadian Hypertension Education Program / Antihypertensive prescriptions was evaluated on Yearly mortality and hospitalization rates per 1000 for stroke, heart failure, and acute myocardial infarction (p=<0.001). Increases in antihypertensive prescriptions were associated with significant reductions in death from stroke, heart failure, and myocardial infarction (P<0.001 for all 3 diseases).
