Smoking cessation: why is it a persistent problem in patients with peripheral artery disease?

Abstract

Nurses play a key role in advising patients to quit smoking, especially those with long-term conditions including cardiovascular disease. Peripheral artery disease (PAD) is an increasingly prevalent condition, and is the third most common presentation of atherosclerotic disease after coronary heart disease and stroke. Smoking cessation is crucial for patients with PAD but can be very challenging. Stopping smoking reduces cardiovascular morbidity and mortality, and improves claudication symptoms in patients with PAD. Those who continue to smoke are at higher risk of disease progression, amputation, myocardial infarction and death, and have poorer therapeutic outcomes. Quitting smoking is difficult, and patients should be offered a combination of behavioural and drug therapy. Nurses can provide several interventions to help patients quit and prevent relapse. A pilot study in a large London hospital found that no smokers had been referred to smoking cessation services by their vascular clinician (although some had been referred by their GP), given brief cessation advice or told how smoking cessation was essential for vascular preservation. Many thought smoking cessation programmes would not work.
