Summary

This study will determine whether or not patients who use a Nicotine Replacement Therapy (NRT) patch prior to their by-pass surgery are more likely to be smoke-free 6 months after their surgery and have fewer post-operative complications

Detailed description

The aim of this project is to 1. To determine if pre-operative, (short-term) NRT, 1 to 3 weeks before surgery, improves the long-term quit rates among smokers undergoing elective CABG surgery. 2. To determine the effect of pre-operative NRT on perceived stress and symptoms of nicotine withdrawal at the time of surgery. 3. To assess, retroactively, the impact of pre-operative cessation on peri-operative complications such as infection rates, respiratory failure, myocardial infarction, stroke, sepsis, shock and prolonged hospital stay. We therefore hypothesize that if NRT is given to smokers during the pre-admission period (1-3 weeks prior to surgery), they are more likely to be biochemically abstinent from cigarette smoking 6 months after hospitalization and will experience fewer peri-operative complications To assess these measures, we have designed a single site, double-blinded randomized controlled trial at the University of Ottawa Heart Institute (UOHI). Patients who are identified as a smoker at their initial visit to the PAU will undergo a baseline assessment and be randomly assigned (1:1) to either active or placebo 21mg NRT patch. They will wear the patch from that baseline visit until the day of their surgery at UOHI. Following their surgery, they will receive a follow up phone call at 1 and 6 months post-discharge. They will complete a series of short questionnaires to assess their smoking status, stress levels and nicotine withdrawal symptoms. Those who identify themselves as being smoke-free will be asked to complete a carbon monoxide breathing test to chemically validate their smoking status. The study protocol will be reviewed by the Research Ethics board at UOHI and all participants will provide written informed consent prior to undertaking any study activities.
