Primary Institution: University of Alberta
Hypothesis
Does a local opinion leader-based quality improvement intervention influence primary care physicians to increase the provision of secondary prevention therapies in their patients with known CAD compared to usual care?
Conclusion
The study aims to evaluate whether interventions endorsed by local opinion leaders can improve the use of secondary prevention strategies in patients with coronary artery disease.
Supporting Evidence
- The study will use a cluster randomization design to avoid contamination.
- The primary outcome is improvement in statin management within six months post-catheterization.
- Secondary outcomes include the use of other medications like ACE inhibitors and beta-blockers.
Takeaway
This study is trying to see if getting advice from respected doctors can help other doctors give better care to heart patients.
Methodology

Potential Biases
Potential for bias in the selection of local opinion leaders and their influence on practice.
Limitations
The study may not be powered to detect differences in clinical events over a short timeframe.
Participant Demographics
