Outcome Measures

Primary Outcomes (1)

  • Smoking cessation

    Change in smoking habits measured by a questionnaire two months after surgery. The participants were asked to report their smoking habits at 6 weeks, 3-6 weeks and 1-3 weeks before surgery, the week of surgery and 1-3 weeks and 3-6 weeks after surgery. The answering alternatives were "did not smoke", "smoked less than ususal" or "smoked as usual". The rate of nonsmoking will be measured at the different time span before and after surgery.

    At two months after surgery

Secondary Outcomes (1)

  • Postoperative complications

    Registered complications within 8 weeks after surgery

Study Arms (4)

Control group

NO INTERVENTION

No information on smoking cessation

Written information, GynOp

ACTIVE COMPARATOR

When reporting being a current smoker in the health declaration on-line the participant receives the following written recommendation in the web-based health declaration "You have increased risks due to smoking. Smoking cessation 6 weeks before surgery and 6 weeks after surgery is recommended"

Behavioral: Information on smoking cessation

Doctor informed

Intervention Model
SINGLE GROUP
Model Details: When smoking is reported by the participant in the web-based health declaration, she is automatically randomized to one of four alternatives. The allocation ratio of randomization is 1:4 between the 4 arms: Group 1 serves as a control group and receives no specific information about smoking cessation; In Group 2 the patient receives directly the following written recommendation in the web-based health declaration "You have increased risks due to smoking. Smoking cessation 6 weeks before surgery and 6 weeks after surgery is recommended"; Group 3 The smoking status of the participant is alerted to the surgeon when filling in the preoperative form with the text " the patient smokes, recommend smoking cessation"; and Group 4, is a combination of Group 2 and 3, i.e. a written recommendation is included in the web-based health declaration as in group 2 and in addition the surgeon is alerted that the patient is a smoker and instructed to recommend smoking cessation as in group 3.
