This study employs a stepped-wedge cluster randomized design involving four primary care practices affiliated with KMH Cardiology. Each family practice constitutes a single cluster.
All participating practices will start as usual standard of care. At three-month intervals, one practice will be randomly selected to crossover from usual standard of care (control group) to the intervention group. There will be a 2-week wash in period when a family practice crosses over from control to intervention. This process will continue until all practices have implemented the intervention, resulting in full intervention by 15 months.
Investigators hypothesize that the Sparrow screening pathway will result in a higher proportion of patients with a positive echo for moderate or severe aortic stenosis than usual care without protocol driven screening.
