Service evaluation of a health behaviour change intervention for patients with peripheral arterial disease

Abstract

This report describes a pilot health behaviour change (HBC) project established by NHS Grampian vascular service. Results are presented in the form of case studies and data. The intervention aimed to support patients with peripheral arterial disease (PAD) to change health behaviour/improve self-management. PAD is a common condition among people aged over 55 years, with significant health implications if not well managed. PAD is caused by narrowing of the arteries, leading to poor blood flow causing pain and cramp mainly in the calf (intermittent claudication). Without proper blood flow, patients with PAD are at high risk of developing serious health problems, including heart attack, stroke, and amputation. Costs associated with PAD are substantial and largely avoidable with effective behaviour change. Smoking is the principle risk factor in the development of PAD. Other modifiable risk factors include obesity and sedentary lifestyle. Service evaluation data was collected at Aberdeen Royal Infirmary with 30 patients attending the vascular outpatient clinic. Patients received a tailored HBC intervention. Post-intervention, fewer participants smoked (67 per cent at baseline, 30 per cent follow-up); average daily step count increased by 1677 steps; average 5kg weight reduction at six month follow-up. Qualitative feedback highlighted increased self-esteem and improved strategies to help cope with PAD.
