Gedetailleerde beschrijving
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.

Interventie / Behandeling |
|---|---|
|
Actieve vergelijker: Intervention
During intervention periods, trained clinic personnel will obtain heart sound recordings at three standard chest positions using the Stethophone application, with at least 30 seconds of recording at each position.
|
The device is a FDA & HC approved mobile application, the Stethophone (developed by Sparrow BioAcoustics), that transforms a smartphone into a digital stethoscope and analytic tool able to identify murmurs that may indicate aortic stenosis.
|
|
Geen tussenkomst: Standard of Care
No study procedures.
Patients will be consented for obtaining data related to ECHO confirmation for of moderate or severe aortic stenosis (if applicable) followed by referral for valve clinic assessment (if need be) for the duration of this study.
