What this trial studies

This randomized, crossover pilot trial will enroll 24 physicians from three Connecticut sites and 48 of their adult patients with cardiovascular disease risk factors. Each physician will deliver a P3-EX personalized exercise prescription to one patient and the standard ACSM-PAVS prescription to their other patient in a randomized sequence, with patients following a 12-week unsupervised program and virtual weekly oversight. The trial will measure usability, acceptability, and feasibility from both physicians and patients using validated questionnaires and will track patient exercise adherence with a self-report diary. Results will inform whether the physician-facing digital decision support tool is practical and satisfactory in real-world clinical settings.

Who should consider this trial

Good fit: Adults aged 18–64 who are currently sedentary and have at least one cardiovascular risk factor (obesity, hypertension, dyslipidemia, or diabetes/prediabetes) are the intended participants.

Not a fit: Patients who are already meeting recommended activity levels, are outside the 18–64 age range, or who require medically supervised or closely monitored exercise programs are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the tool could help physicians give clearer, personalized exercise prescriptions that increase patient activity and may improve cardiovascular risk factors.

How similar studies have performed: Exercise prescriptions and digital health tools have shown promise for improving activity and risk factors, but physician-facing prescription decision-support tools like P3-EX remain relatively novel and have limited randomized pilot data.
