NCT02482233
The purpose of this pilot randomized trial is to determine the feasibility of e-cigarettes and telephone counselling (compared to transdermal nicotine replacement and telephone counselling) as a harm-reduction tool that may lead to increased smoking cessation in the perioperative setting in smokers presenting for elective surgery at the San Francisco Veterans Affairs Medical Center. Secondary outcomes include acceptability of e-cigarettes over transdermal nicotine replacement, length-of-stay in the post-anesthesia care unit, hospital length-of-stay, postoperative complications within the first 30-days, and smoking status 8-weeks after randomization. This pilot study is designed to provide the preliminary data necessary to plan and fund a larger-scale randomized clinical trial that will assess the utility of e-cigarettes in achieving smoking cessation perioperatively. Our ultimate goal is to add to the limited existing data on the safety and efficacy of e-cigarette use in smoking cessation, specifically in the perioperative setting where the risks of continued smoking are great and the motivation to stop is high.
