Big data takes on heart disease: can a toolbox of info boost statin use?
NCT ID NCT04067297
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a 'toolbox' of educational materials—including report cards for doctors, patient handouts, and an online decision aid—can increase the use of cholesterol-lowering statins in communities with high rates of heart disease. Researchers will track prescription data from over 500,000 people in Ontario using big data. The goal is to see if this real-world approach helps prevent heart attacks and strokes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Lipid management toolbox (educational materials, report cards, decision aid, videos)
- What this could lead to
- If successful, this approach could show that using big data in real-world settings can improve cholesterol management and prevent heart attacks and strokes in high-risk communities.
- What could go wrong
- This is an observational-style trial testing a community-level intervention, not a new drug. The results may not apply to other regions or populations, and the toolbox may not change prescribing habits as hoped.
