About this trial
In Germany, coronary CT offers an accurate and less burdensome alternative to cardiac catheterisation for evaluating suspected coronary artery disease, but it is still underused. The IMPRO stepped-wedge trial tests a new, nationwide care model (NVF) in 16 regions to improve guideline-based intersectoral implementation of coronary CT and assess its impact on cardiovascular outcomes and healthcare costs. If effective, the model of care (NVF) could be adopted across Germany to enhance care quality while reducing unnecessary procedures and expenses.
