About this study

Diabetes is a common and serious chronic disease. However, there is a large gap between the level of care that people should receive (based on research and guidelines) and the level of care they actually receive. With the release of their 2008 Clinical Practice Guidelines, the Canadian Diabetes Association has a strategy to improve heart disease screening and treatment for people with diabetes. This study will evaluate whether the strategy works. The focus of the strategy was to give all family physicians in Canada a Toolkit in June 2009 to help them delivery better care for their diabetic patients. In Ontario, only half of doctors received this Toolkit. We will compare the quality of care received by diabetic patients whose doctors received this Toolkit versus those who doctors did not.

Read the detailed description

A cardiovascular disease Toolkit was developed by the Canadian Diabetes Association and mailed to family physician with the Spring/Summer 2009 edition of the newsletter, Canadian Diabetes. The Toolkit was packaged in a brightly-coloured box with Canadian Diabetes Association branding, and contained: 1) an introductory letter from the Chair of the practice guidelines' Dissemination and Implementation Committee; 2) an eight page summary of selected sections of the practice guidelines targeted towards primary care physicians; 3) a four page synopsis of the key guideline elements pertaining to cardiovascular disease risk; 4) a small double-sided laminated card with a simplified algorithm for cardiovascular risk assessment, vascular protection strategies and screening for cardiovascular disease; and 5) a pad of tear-off sheets for patients with a cardiovascular risk self-assessment tool and a list of recommended risk reduction strategies.

Questions about this trial

What is this clinical trial studying?

A study testing Toolkit in people with Diabetes Mellitus and Cardiovascular Disease, run by Sunnybrook Health Sciences Centre 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 1 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 24 Nov 2014. 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?

Death or non-fatal myocardial infarction (time frame: Up to 10 months). 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 NCT01411865, which also lists 1 linked publication.

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 24 Nov 2014.
