Brief Smoking Intervention for Women Undergoing Breast Cancer Surgery

Smokers are at greater risk of developing postoperative complications. The connection between smoking and cardiovascular and pulmonary disease is furthermore well documented. Smoking cessation 6 weeks before orthopaedic surgery significantly reduces the risk of developing postoperative complications. However, smoking cessation for an even shorter period may theoretically have similar effects on postoperative complications. Intensive smoking intervention programmes increase long-term smoking cessation rates significantly. Little evidence is available on the efficacy of brief smoking intervention programmes for newly diagnosed cancer patients. This study therefore aims to examine the effect of a brief smoking intervention on postoperative complications and long-term smoking cessation rates in women undergoing breast cancer surgery. The study is a randomised clinical trial in which study participants are randomised by block randomisation to either standard care (control group) or a brief preoperative smoking intervention (intervention group). Patients in the intervention group are counselled to comply with an intended perioperative smoking cessation period of 13 days. The intervention and control groups will be compared up to 12 months postoperatively in regard to frequency of postoperative complications and smoking cessation rates. Additionally, experienced stress and nicotine withdrawal symptoms during the perioperative smoking cessation period will be compared between the groups.
