Description of intervention(s) / exposure
This project will utilise deliver a m-Health smoking cessation intervention opportunistically targeted to a time point at which patients have been shown to be particularly receptive to behaviour change (before a surgical procedure).

The intervention for this project entails a text message program delivered to participants over a 12 week period of time, with 4 messages per week. The content of these text messages will include 24 smoking cessation messages and 24 general messages, which include 1) healthy lifestyle (i.e. diet and physical activity) and 2) information specific to Westmead Hospital pre-admission and surgical services (eg. Parking locations, typical clinic duration, items to bring etc.). The primary outcome of self-reported smoking cessation will be assessed at 12 weeks and 12 months.

Participants will be recruited via screening of recommendation for surgery documents at Westmead pre-admission clinic. At this point, our investigators based at Westmead hospital will contact the participants and fill out the initial questionnaire surrounding their current smoking habits and general health indices. The questionnaire data is recorded on the RedCap database which will then randomise the participants to the intervention or control group. Participants in the intervention group will receive text messages as above, via current software previously used to deliver text message based interventions in high risk cardiology patients (used for clinical trial TEXT ME). This intervention is delivered from the cardiology research department at Westmead hospital. At the end of the 12 week period - investigators will again contact the participants to fill out the follow up questionnaire regarding changes to smoking habits/smoking cessation/increased willingness to quit.

This research aims to establish the feasibility and effectiveness of a 12 week SMS delivered smoking cessation program delivered during the pre-operative waiting period before a scheduled surgical procedure.

The initial welcome message will be sent followed by 8 admin messages first. In the first week of the program there will be 4 messages and after that 3 messages per week. After the 8 admin messages the participants will receive 24 smoking cessation messages, 10 healthy lifestyle messages and 6 messages with information specific to Westmead Hospital pre-admission and surgical services.

The message delivery is monitored via an automated query to the messaging service provider. This query is performed for each message for 7 days after the message has been dispatched to determine whether the message has been delivered or not. This data is written to an excel spreadsheet.

Participants will be encouraged not to reply to the messages however any replies will be monitored and responded to as necessary. Participants will be able to opt out of the intervention at any time by replying to a message with the response 'STOP'.

If participants reply stop the messages will be ceased but they will still be contacted for followup. They will not be replaced as a drop off rate was factored into the power calculations.

Behaviour
Comparator / control treatment
The study participants will be randomised to either the intervention group which will receive a text message program to assist with smoking cessation, or a control group that will receive standard peri-operative communication only.

The controls will receive one message in the first week of the program, informing them that they are in the control group. In the last 4 weeks of the 12 week period they will receive 2 admin messages per week (8 admin messages in total).

Standard peri-operative communication includes information regarding pre-admission clinic and surgical services (eg. parking locations, typical clinic duration, items to bring etc.). This is relayed to patients typically via text message unless they do not have a mobile phone.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After recruitment and the completion of the initial study questionnaire, the data management system Redcap will randomise participants to either the intervention or control group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
Masking / blinding
Blinded (masking used)

Statistical methods / analysis
Statistical Methods
Statistical analysis will be conducted on the principle of intention to treat. Participants will be analysed by the original allocated groups. Statistical analysis will be conducted using SAS® software (version 9.4, SAS Institute Inc., Cary, NC, USA). Continuous variables will be reported as mean (standard deviation) or median (interquartile range), and compared using the t test or Mann-Whitney-Wilcoxon test. Categorical variables were reported as frequency (percentage), and compared using the chi-squared test or Fisher’s exact test. All statistical tests will be 2-tailed with a significance level of 5%. No adjustments for multiple comparisons will be made as the number of pre-defined outcomes is small. Subgroup analysis will be performed by clinical priority category.
