Brief Summary

Smoking continues to be a burden to the healthcare system in Canada. It is well-known that smokers suffer more complications and higher risk of mortality after surgery than non-smokers. A quality improvement project at Royal Columbian Hospital recently showed that it is possible to implement a smoking cessation bundle for all current smokers during their preadmission clinic visit. However, due to the COVID-19 pandemic, much of the bundle was abandoned as it relied heavily on in-person interactions. The investigators wish to study the effect of a structured smoking cessation bundle, delivered remotely, on smoking cessation and postoperative complications. The aim is to determine the feasibility of giving the remotely delivered bundle to elective surgical patients before or around the time of a preadmission clinic visit, and whether it can reduce smoking rates and postoperative complications versus the standard uncoordinated advice.

Outcome Measures

Primary Outcomes (4)

  • Uptake of smoking cessation resources

    The primary outcome is the participant's self-reported rate of uptake of smoking cessation information and accessing available resources. Uptake will be assessed by a brief questionnaire given at each of the follow-up time points asking which resources were accessed and if NRT was used.

    Day of surgery

  • Uptake of smoking cessation resources

    The primary outcome is the participant's self-reported rate of uptake of smoking cessation information and accessing available resources. Uptake will be assessed by a brief questionnaire given at each of the follow-up time points asking which resources were accessed and if NRT was used.

    30 days postoperatively

  • Uptake of smoking cessation resources

    The primary outcome is the participant's self-reported rate of uptake of smoking cessation information and accessing available resources. Uptake will be assessed by a brief questionnaire given at each of the follow-up time points asking which resources were accessed and if NRT was used.

    8 weeks post-randomization

  • Uptake of smoking cessation resources

    The primary outcome is the participant's self-reported rate of uptake of smoking cessation information and accessing available resources. Uptake will be assessed by a brief questionnaire given at each of the follow-up time points asking which resources were accessed and if NRT was used.

Study Arms (2)

Control group

NO INTERVENTION

The control group will have their preadmission clinic telephone call as normal and may be given advice to quit smoking and information about available smoking cessation resources over the phone.

Intervention group

EXPERIMENTAL

The intervention group will be emailed (or postal mailed) the smoking cessation bundle with educational video, brochure, referral to the Smokers' Helpline and direct referral to an online pharmacy for nicotine replacement.

Other: Remote smoking cessation bundle

Interventions

The bundle is a remote version of what has previously been described in prior literature, which includes: 1. A brief (\<5 minutes) advice 2. Preoperative smoking cessation video prepared by QuitNow 3. Patients will be provided brochures on smoking cessation 4. A referral will be faxed (or internet-registered) to the Quitnow.ca Smokers' Helpline 5. All patients will be requested to participate in the provincial Smoking Cessation program that provides a free 12-week supply of NRT once per year.

Intervention Model
PARALLEL
Model Details: Study Design This pilot randomized controlled trial with two parallel arms will be undertaken with current smokers who are scheduled for elective surgery at RCH. Participants will be randomized to a smoking cessation bundle (video, electronic or mailed brochure, referral to QuitNow.ca Smokers' Helpline and pharmacological smoking cessation therapy) or standard care (advice to quit and inconsistent recommendation of resources). All current adult smokers being scheduled for elective surgery at RCH will be invited to participate. The investigators plan on recruiting 30 participants with 15 participants per group. Every eligible patient will be invited to participate.
