Study type
Interventional
Description of intervention(s) / exposure
Randomised controlled trial of uptake, use and smoking cessation outcomes after an offer of smoking cessation help in adult elective surgery patients who smoke, compared to standard care. Intervention group smokers receive an invitation, pre-surgery, when name is placed on the elective-surgery wait-list for free nicotine replacement therapy (NRT) mailed to their home, printed quit information and enrollment in Quitline call-back service for telephone support. The intended use is for assistance with pre-surgical quitting. The dose of NRT will vary according to nicotine dependence (a) Highly dependent (smokes >15/day): 5-weeks of NRT patches, reducing dose regimen as follows: Size, 21-mg/worn for 24-hrs, changed daily, duration of use=3 weeks, then size 14-mg/worn for 24hrs, changed daily, duration of use=1 week then size 7-mg/worn for 24hrs, changed daily, duration of use=1 week, PLUS 2mg nicotine lozengers, to be used in conjunction with patches if cravings occur, maximum 7 lozengers per day, supply of 72 lozengers. (b) Moderately dependent (10-15/day): 3-weeks of patches, size 14-mg/worn for 24/hrs, changed daily, duration=2 weeks, followed by size 7-mg/worn for 24hrs, changed daily, duration =1 week, PLUS 2mg nicotine lozengers, to be used in conjunction with patches if cravings occur, maximum 7 lozengers per day, supply of 72 lozengers. (c)Light/intermittent/social (<10/day): No patches, 2mg nicotine lozengers, to be used if cravings occur, maximum 7 lozengers per day, supply of 72 lozengers. Participants in intervention group may request the NRT products at any time prior to their operation date, including an additional course of treatment if the initial products posted did not achieve smoking abstinence prior to surgery. The additional printed information sent to smokers in the intervention group prior to surgery is an existing Quitline resource, https://www.quit.org.au/documents/231/AQ710_Smoking_and_Surgery_DL_update_v5.pdf
Participants quit by surgery for >24 hours will be offered a "Relapse Prevention Kit" on day of operation for use after hospital discharge. This consists of further 2mg NRT lozengers, to be used if cravings occur after hospital discharge, and printed relapse prevention advice. This printed advice will be existing Quitline resources:

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified randomisation based on daily amount smoked prior to surgery, using a computerised random number generator; (https://www.randomizer.org). Allocations to either Intervention or Control groups will be concealed in opaque, numbered envelopes. 3 strata:
1-9 cigarettes a day
10-15 cigarettes a day
>15 cigarettes a day
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
Intervention assignment
Parallel
Other design features
1:1 randomisation within each strata based on amount smoked to intervention or control
Phase
Phase 4
Type of endpoint/s
Efficacy
Statistical methods / analysis
Given likely 10% abstinent in Control and 20% Intervention group from pilot ACTRN12616000073404 , 199 participants per group required, 5% significance level and 80% power. 20% additional subjects will be added to account for drop-out/loss-to-follow-up/never had their operation etc. Categorical data (quit/not quit etc) will be compared in contingency tables, Fishers exact test will used to determine significance.
