NCT05029739

Brief Summary

The specific study aim is to determine whether a 12-week digitally delivered behavior change intervention for patients with peripheral artery disease increases walking ability, reduces smoking, improves quality of life and improves medication adherence. The primary and secondary endpoints will primarily be captured at a 12 weeks follow-up visit, but a follow-up visit after 12 months is also planned; to assess longer term effect on outcomes and healthcare cost.

Outcome Measures

Primary Outcomes (1)

  • Six-minute walk test.

    Change in objectively measured (pain-free and maximal) walking capacity (as measured with the 6-Minute Walk Distance Test) from baseline to 12 weeks and 12 months

    12 weeks and 12 months

Secondary Outcomes (10)

  • Smoking status

    12 weeks and 12 months

  • Increased readiness to quit smoking.

    12 weeks and 12 months

  • Medication adherence improvement

    12 weeks and 12 months

  • Disease-specific health-related quality of life.

    12 weeks and 12 months

  • Comparing outcomes to health literacy

    12 weeks and 12 months

  • +5 more secondary outcomes

Study Arms (2)

E-intervention group

EXPERIMENTAL

Participants will be instructed to download a life-style-changing mobile app to which they will have access for 12 weeks. After the first week of the program, participants who smoke will be offered to incorporate smoking cessation support into their PAD program. These changes are minor and not intended to divide the intervention group in two but instead to personalize the study experience. The program aims to empower positive lifestyle change by gamification, altruistic rewards, and engaging content with relevant tasks or missions to be completed. Beyond this, all patients in the interventional arm will also receive standard of care as defined below for the control arm.

Device: A PAD-specific smartphone application (e-intervention) developed for patients with Peripheral Artery Disease

Standard of care - control group.

ACTIVE COMPARATOR

All patients in the control arm will receive best medical therapy including start or optimization of secondary preventive pharmacotherapy, smoking cessation advise and advise on modifiable risk factors. The control arm will also receive an information leaflet about relevant lifestyle modifications for PAD. After the baseline measurements and data collection, there will be no scheduled visits to a health care provider until week 12.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults with confirmed PAD referred to a vascular surgery unit for evaluation and treatment, currently on best medical treatment and own/have access to a mobile smartphone
  • Stable PAD disease and limb symptoms during the last 3 months.
  • PAD is the activity-limiting disease
  • Abnormal resting ankle-brachial index (ABI) (≤0.90), falsely elevated ABI above 1.3 or a 30% post-exercise ABI reduction.

You may not qualify if:

  • Critical limb ischemia, prior amputation, or other diseases/ impairment that limit the walking ability and the 6-minute walk test's proper conduct
  • Cognitive impairment
  • Prior revascularization less than one year ago
  • A planned revascularization procedure during the upcoming 12 months (known at baseline).
