Nicotine Dependence and Willingness to Quit Smoking in Vascular Surgery Patients.

BACKGROUND

Smoking rates have declined; however, it remains the primary modifiable risk factor for vascular disease. While vascular surgeons often advise patients to quit, few provide assistance. We sought to understand patients' interest in quitting and determine factors that influence this willingness to quit.

METHODS

Anonymous surveys were given to vascular surgery clinic patients in a single institution over a 5-month period. Demographic information, smoking status, cessation attempts, and barriers to quitting were obtained. Nicotine dependence was determined using the Fagerstrom Test, and willingness to quit was assessed using a contemplation ladder. Patient's willingness to quit was evaluated in relation to symptomatic status, previous/planned operation, and nicotine dependence levels.

RESULTS

A total of 490 patients (92%) completed the survey with 109 (22%) current smokers, 195 (40%) former smokers, and 186 (38%) never smokers. Never smokers were more likely to be female and employed while smokers were more likely to be disabled. Although 51% of smokers displayed moderate/high nicotine dependence, 54% demonstrated willingness to consider quitting within 6 months. The primary barrier to cessation identified was previous failed attempt(s) to quit in 44%. Most (90%) had previously attempted quitting, 63% attempted 3 or more times, and the most common technique used was "quitting cold turkey". Fifty-nine percent of patients reported physicians' had offered assistance in cessation, but only 2% had been in a cessation program. There was no correlation between willingness to consider quitting and symptomatic status, previous/planned operation, or nicotine dependence. Smokers of less than 10 cigarettes/day had a lower nicotine dependence level (P = 0.0001) and higher willingness to consider quitting (P = 0.0015), as did those who had fewer failed prior attempts to quit and who did not believe it was too late to quit.

CONCLUSIONS

Most of our vascular patients self-report as nonsmokers. Over half of those who smoke demonstrate willingness to consider quitting within 6 months, which is not dependent on nicotine dependence, previous/planned operation, or symptomatic status. Those who smoke less than 10 cigarettes per day, have fewer past failed attempts to quit, and believe that it is not too late to quit are more likely to consider quitting. Vascular surgeons should be more aware of previous quit attempts and patterns of smoking and be proactive in assisting patients in cessation attempts.
