About this study

Official title: Alberta Clinical Trial in Optimizing Hypertension: The RxAction Study

The purpose of this study is to evaluate the effect of enhanced pharmacist care (patient identification, assessment, education, prescribing/titration of antihypertensive medications and close follow-up) on systolic blood pressure (BP) reduction in patients with poorly controlled hypertension in the community setting.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Enhanced pharmacist careOther

    Also called Treatment group

    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 pharmacist will also review the patient's current hypertensive therapy regimen and decide on the options for improvement of BP control (lifestyle modification, increase dose, additional BP medications), and implementation of these strategies.

  • Usual CareOther

    Also called Control

    Patients randomized to usual care will receive a wallet card for BP readings, pamphlet on BP and usual pharmacist and physician care. Patients will be seen at 12 weeks for interim BP measurement only. Both groups of patients will be seen at 24 weeks for BP measurement.

Questions about this trial

What is this clinical trial studying?

A study testing Enhanced pharmacist care in people with Hypertension, run by University of Alberta at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of difference in change in systolic BP between enhanced care and usual care (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00878566, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2015.
