Assessing the impact of a nurse-led health education intervention for people with peripheral vascular disease who smoke: the use of physiological markers, nicotine dependence and withdrawal

This study evaluated the impact of a nurse-led health education programme on the behaviour, nicotine dependence and nicotine withdrawal in patients who smoke and suffer from peripheral vascular disease, based in a large teaching hospital in the north of England. Smoking behaviour was measured by self report, end-expired carbon monoxide and urinary cotinine. Nicotine dependence and withdrawal were measured using a nicotine dependence scale and a nicotine withdrawal scale. The findings demonstrated that the programme did have some impact on behaviour. The study raised issues concerning the measurement of physiological markers for smoking as nursing outcomes. Issues about the measurement of nicotine dependence and withdrawal are highlighted.
