Diabetes Risk Evaluation and Microalbuminuria in Saskatchewan First Nations Peoples

Two community-based strategies for controlling hypertension in First Nations people with existing hypertension and diabetes were compared. In the intervention group, a home care nurse followed a predefined treatment algorithm of pharmacologic antihypertensive therapy. In the control group, treatment decisions were made by each subject's primary care physician. The primary outcome measure was the difference between the 2 groups in teh change in systolic blood pressure after 12 months.
