Smoking Cessation Prior to Gynecological Surgery

Overview

This study evaluates whether current smokers scheduled for gynecological surgery will stop smoking to a higher extent if they or the surgeon is exposed to information on smoking cessation prior to surgery in a web-based questionnaire in the Swedish National quality register for gynecological surgery, GynOp.

Peri-operative smoking cessation should be introduced 4-6 weeks before surgery and continued 4-6 weeks after surgery to decrease postoperative complications. The purpose of the study is to increase the exposure to smoking cessation information pior to surgery using a web-based quality register. The hypothesis is that this will lead to an increase in perioperative smoking cessation. Women scheduled for gynecological surgery who report current smoking will be enrolled in the study. They will be randomly assigned to different sources of information about smoking cessation before surgery. The web-based Swedish national quality register for gynecological surgery, GynOp, will be utilized for randomization, obtaining information about the participant and the surgery performed as well as for follow-up. GynOp The register was established in 1997 and 90% of gynecological surgical clinics in Sweden contribute information. The conversion from paper forms to on-line registration started in 2008. When scheduled for surgery a health declaration and a questionnaire about symptoms is sent to the patients primarily via their e-mail address for direct on-line registration. This is used in 41% of the cases and the response rate has been reported to be 83%. If an e-mail address is missing, or if preferred by the patient, information is obtained by postal questionnaires (today used in 59% with a response rate of 87%). It has been previously reported that there were no differences in patient characteristics between these two means of contact except that patients without an e-mail address were slightly older and answered more frequently than patients with e-mail. The advantage of the web-based version is not only that the health declaration is sent directly to the clinic and automatically included in the medical record, but relevant information to the patient can be added in the health declaration. The on-line web-version can also be used in a randomization process, which we will utilize in this study. Data in the register is collected prospectively from patient questionnaires and doctors' forms. The patient receives written information about the register and has the opportunity to decline participation. Pre-operatively, the patient fills in a questionnaire including a health declaration with questions on comorbidity, medication and smoking status. The surgeon registers data on preoperative findings and surgical history at the enrollment before surgery. Peroperative data and events before discharge are also registered in two different forms by the surgeon. Eight weeks postoperatively the patient receives a questionnaire with questions concerning the results of the surgery and any complaints or complications. The forms are evaluated by the surgeon and data registered if there have been any complications. The randomisation process 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 will be 1:4 between the 4 arms: Group 1 serves as a control group and receives no specific information about smoking cessation Group 2 the participant 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 patient is alerted to the surgeon when filling in the preoperative form with the text " the patient smokes, recommend smoking cessation" 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. In the postoperative questionnaire two months after surgery the participant is asked to participate in a research study including questions about smoking cessation and an informed consent form will be presented and completed. Hence, she will thereby be blinded to the study when she receives the smoking cessation information in the preoperative questionnaire. The intention for this procedure is to avoid introducing any bias of being included in a study and to be able to study the effect of a recommendation in the register in a real world setting. This was accepted by the Ethics Committee and to be exposed to smoking cessation information was not considered an ethical problem as patients are routinely given written information on smoking cessation by the clinics even outside the study. The patient has the opportunity to decline participation two months after surgery when the additional questionnaire on smoking cessation is presented. Five questions on smoking cessation will be added to the ordinary postoperative questionnaire. The questions includes whether or not the woman has received smoking cessation information, from whom she has been given the information and the duration of smoking cessation in connection to surgery. These questions has gone through several phases of validation prior to study start. The randomization process in the register has also been tested thoroughly since this is the first time a randomized study is carried out in this register.
