Alberta Clinical Trial in Optimizing Hypertension

The study is a randomized, controlled trial of enhanced pharmacist care, with the unit of randomization as the patient. Participants will be randomized to enhanced pharmacist care (patient identification, assessment, education, close follow-up and prescribing/titration of antihypertensive medications or usual care. Participants will be patients in Alberta with undiagnosed or uncontrolled BP as defined by the Canadian Hypertension Education Program. The primary intervention will be enhanced pharmacist care. Pharmacists will assess patients with regards to cardiovascular risk reduction including reviewing BP control, treatment goals and determining lifestyle modifications for the patient to undertake to help manage their BP. The primary outcome will be a comparison of difference in change in systolic BP between enhanced care and usual care at 24 weeks follow-up. Secondary outcomes include the number of patients at their BP target at 24 weeks, number of new antihypertensive medication starts, number of antihypertensive dosage changes, number of antihypertensive medication changes and number of new prescriptions for ASA and cholesterol medications.
