Effect of a Perioperative Smoking Cessation Program on Smoking Cessation/Reduction and Perioperative Complications

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether a perioperative smoking cessation program, implemented at least 3 weeks prior to elective surgery, is effective in increasing rates of smoking cessation or reduction. Intraoperative and immediate postoperative complications will also be compared.

Detailed Description
-----------------
Previous studies have shown that patients have up to one-third fewer complications after surgery when they quit smoking at least several weeks before surgery. Nicotine replacement therapy (which relieves cravings for cigarettes) and support by healthcare professionals have been shown to help patients quit smoking, particularly when encountering a major health event (e.g. surgery). In addition, quitting smoking in preparation for surgery sometimes results in quitting for a longer period of time after surgery, giving these patients the health benefits of long-term smoking cessation such as reduced rates of cancer and heart disease. The preadmission clinic at St. Joseph's Health Care, London, Ontario, is assessing how effective a new 'Stop Smoking' program is for patients preparing for surgery. The program will include brief counselling in the clinic, smoking cessation brochures, six weeks of free transdermal nicotine replacement therapy and a referral to the Canadian Cancer Society's Smokers' Helpline telephone advice line. Patients that are smokers and preparing for their elective surgery will be invited to join the study, then be assigned to a group that either participates in the program or not. These groups will then be compared in terms of success at quitting smoking and complication rates around the time of surgery.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| smoking cessation | Smoking cessation is defined as exhaled carbon monoxide (CO) of equal to or less than 7ppm on the day of surgery. | date of surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| smoking cessation/reduction | Smoking cessation/reduction by self-report. Smoking cessation defined as zero cigarettes in the 7 days before surgery (but exhaled CO > 7ppm) Reduction defined as 50% or less of initial self-report. | day of surgery | 
| Intraoperative complications and immediate post-operative complications | Events occurring in the operating room or post-anesthetic care unit (PACU) as reported by a blinded anesthesiologist or blinded PACU nurse: Cardiovascular complications, Respiratory complications, Other (detailed description exceeds character limits) | day of surgery | 
| Time until PACU readiness for discharge / actual time in PACU | The time of arrival in PACU until the time the patient is deemed ready for discharge in accordance with hospital routine scoring system. The actual time spent in PACU (arrival until discharge) will also be compared. Patients bypassing PACU (e.g. patients having only sedation transferred directly from the operating room to surgical daycare prior to discharge home) will be considered separately. | day of surgery | 
| Unanticipated hospital admission | Patient booked as one-day stay, but later admitted to inpatient ward. | day of surgery | 
| Hospital length of stay | For inpatients only, the time from admission to surgical daycare until the patient is discharged home from the hospital. | until hospital discharge | 
| Smoking cessation at 12 months | Self-reported smoking zero cigarettes in the 7 days prior to phone call. Phone call will occur at any time during the 12th month after surgery. | 1 year |
