Background: The goal of this study is to evaluate the efficacy of a smoking cessation intervention performed by a vascular surgery provider compared with current smoking cessation practices. Methods: Patients with peripheral arterial and aneurysmal disease who presented to the vascular surgery service at a tertiary care center over a 9-month period were randomized to either control or intervention group. Both control and intervention groups received 2 weeks of free nicotine patches and referral to an outpatient smoking-cessation program. The intervention group additionally received a brief presentation by a vascular surgeon regarding the benefits of smoking cessation, with a focus on vascular complications. At enrollment and at follow-up, patients underwent carbon monoxide breath testing and completed a survey. The primary outcome was smoking cessation or reduction among control and intervention groups in patients who underwent medical management, endovascular procedures, or open surgical procedures. Fisher's exact test was used to assess the primary outcome among groups. Results: Fifty-nine patients were enrolled in the trial initially, but 55 had 1-month follow-up (control n = 28, intervention n = 27) and 52 had long-term follow-up (control n = 28, intervention n = 24). By long-term follow-up, 40 patients (77%) had reduced smoking by at least 50% and 16 patients (31%) had quit completely. At long-term follow-up, 88% of patients in the intervention group and 68% of patients in the control group reduced smoking (P = 0.1). Conclusions: A large proportion of vascular patients who received 2 weeks of nicotine replacement with or without the addition of brief smoking cessation counseling delivered by a vascular surgery provider were able to reduce smoking and maintain reduction after 6 months. Delivery of a brief standardized smoking cessation counseling session by a vascular surgery provider is safe and feasible. Additional randomized controlled trials with large enrollment periods and long follow-up are needed to determine the efficacy of this intervention in comparison to standard care.
