A Novel Digital Tool Physicians Can Use to Prescribe Exercise to Patients With Cardiovascular Disease Risk Factors

Summary

The investigators will conduct a feasibility and pilot efficacy randomized controlled trial to test the usability and user satisfaction of an evidence-based digital health tool the investigators developed for physicians to use to Prioritize Personalize Prescribe EXercise (P3-EX) to patients with cardiovascular disease (CVD) risk factors. The investigators will recruit 24 physicians from two local hospitals in CT, USA. Physicians will recruit two patients each (N=48) having CVD risk factors. Physicians will deliver a P3-EX exercise prescription (ExRx) to one of their patients (n=24) and the American College of Sports Medicine Physical Activity Vital Sign (ACSM-PAVS) ExRx to the other (n=24) in a random sequence crossover design. Physicians and patients will rate the feasibility and acceptability of each method using validated questionnaires. Patients will perform their prescribed ExRx for 12 weeks and complete a self-report exercise diary to monitor exercise adherence with virtual oversight from University of Connecticut (UConn) Graduate Research Assistants. Before and after the exercise intervention, the investigators will measure patient CVD risk factors and physical activity (PA) levels via accelerometry. The primary aim is to evaluate the feasibility and acceptability of P3-EX for physicians to use to prescribe exercise to patients with CVD risk factors, and the secondary aim is to explore the preliminary efficacy of P3-EX to improve patient CVD risk factors, PA levels, and exercise adherence. The investigators hypothesize P3-EX will be feasible for physicians to use to prescribe customized exercise routines for patients with CVD risk factors, and physicians and patients will be satisfied with P3-EX.
