Primary Care Audit of Global Risk Management

Study Overview
=================
Brief Summary
-----------------
Assessing the perception of Canadian Primary Care Physicians towards global cardiovascular risk assessment. Correlating physician perceptions to actual practice data, gathered via a retrospective chart audit. Evaluating the impact of a prospective educational and peer-practice pattern intervention on future assessment o cardiovascular risk and Assessing the role of carotid atherosclerosis assessment(Carotid IMT and plaque) as an adjunct to global risk prediction.

Detailed Description
-----------------
The majority of cardiovascular events occur in people with low to intermediate Framingham Risk Score. Despite evidence-based guidelines, the appropriate use of lipid-lowering therapies in this population remains limited and controversial. Strategies to refine risk stratification in primary prevention have been poorly adopted. Dissemination of practice-changing trials and closing the care gap in primary care remain a priority and a challenge. Considerable confusion remains regarding the optimal application of lipid-lowering therapy in primary prevention. Importantly, it remains largely unknown which tools or techniques are used by Canadian primary care physicians to identify global vascular risk, and what barriers exist to implementing risk reduction therapies in such individuals. For primary prevention of patients with normal levels of LDL-Cholesterol who are at increased risk on the basis of elevated hsCRP, it remains unproven whether statin therapy will effectively reduce vascular event rates. The JUPITER trial was launched in 2003 comparing rosuvastatin with placebo in 18,000 primary prevention patients with LDL-cholesterol of less than 3.36mM who also have an hsCRP of greater than 2 mg/L. This trial has been stopped early due to unequivocal morbidity and mortality benefits in favor of the treatment strategy, and the final results will be available in early November, 2008. JUPITER, once published, will require a major change in physician behavior with respect to screening and treating cardiovascular risk.
