Background: Smoking cessation intervention is a peripheral arterial disease (PAD) performance measure, but it is unknown how smoking behavior changes after PAD evaluation and what methods of smoking cessation are used.
Methods: A cohort of 1272 patients with PAD and new or worsening claudication were enrolled from 16 PAD clinics (2011-2015) across the US, the Netherlands, and Australia. Smoking status and cessation interventions were collected through interviews at initial presentation and at 12 months. Based on baseline smoking status, patients were further categorized by their 12-month smoking status: quit vs not.
Results: On presentation, 474 (38%) patients were active, 660 (52%) former, and 138 (11%) never smokers. Among current smokers, 84% smoked at 12 months and 16% quit, while 4% of former smokers restarted smoking. The Netherlands had a higher proportion of current smokers (201/382, 53%) compared with Australia (32/94, 34%) and the US (241/796, 30%; p<.0001). Overall, 356 (75%) smokers received some form of cessation intervention: the majority (74%) received physician advice only, whereas only 16% received formal counselling, and 7% nicotine replacement therapy (NRT). While the Netherlands (23%) and Australia (35%) had higher quit rates at 12 months compared with the US (8%; p<.0001), only 4% of smokers in the Netherlands received formal counseling and NRT compared with 19% in Australia, and 39% in US (p<.0001). No cessation therapies were associated with successful quit rate at 12 months in our cohort (p>0.36 for all).
Conclusions: More than one-third of patients with PAD symptoms are active smokers at the time of presentation and over 80% continue to smoke 12 months later. Very few patients receive cessation counselling and nicotine replacement therapies.
