Structured PICO

Does the initiation of the Canadian Hypertension Education Program improve guideline-recommended antihypertensive prescribing trends in hypertensive patients?

P
Population
Two Ontario cohorts: 1) all hypertensives prescribed therapy, and 2) 166,018 nondiabetic individuals over age 65 newly treated for hypertension.
I
Intervention
Initiation of the Canadian Hypertension Education Program (CHEP) in 1999
C
Comparator
Pre-1999 prescribing trends (time series analysis before and after 1999)
O
Outcome
Antihypertensive prescription rates (total and by specific drug classes including thiazide diuretics, beta-blockers, calcium channel blockers, and ACE inhibitors)

The implementation of a national hypertension education program was temporally associated with significant increases in the prescribing of guideline-recommended antihypertensive medications.

Cite This Study

Campbell et al. (2005) conducted a cohort in Hypertension (n=166,018). Canadian Hypertension Education Program vs. Pre-1999 prescribing rates (before program initiation) was evaluated on Antihypertensive prescription rates. Initiation of the Canadian Hypertension Education Program in 1999 was temporally associated with a 58% annual increase in total antihypertensive prescriptions in Ontario.
