Background: In 2006, we reported the smoking status of surgical patients, and the factors relating to preoperative abstinence from cigarettes. Recently implementation of smoke-free policies has increased in Japan. Therefore we performed preoperative interview of 1,124 patients scheduled for elective surgery in 2011 (during 6 months), and compared the results with those of the same interview of 1,968 patients in 2006 (during 12 months).
Methods: Anesthesiologists interviewed all patients using a standardized questionnaire regarding: medical history, smoking history, and awareness of the risks of perioperative smoking.
Results: Current smoking rate was not different between 2006 (7%) and 2011 (7%). It was more difficult to quit smoking preoperatively for female patients in 2011 (P = 0.030), and those with benign disease in both 2006 (P = 0.006) and 2011 (P = 0.050) [smoker vs ex-smoker (< three months)]. There was no improvement in awareness of the perioperative risk of smoking between 2006 and 2011.
Conclusions: At present, the importance of perioperative smoking cessation has not been sufficiently well-known for the surgical patients. Health care workers should be more aware of the importance of informing patients that preoperative abstinence from cigarettes may decrease perioperative complications.
