Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention. The intervention will be 3 months in duration and includes three components:
(1) Provision of a Quit Pack: participants will be mailed a Quit Pack. The Quit Pack includes readily available universal quitting resources from sources such as Quit Victoria. The Quit Pack includes pamphlets and resources on quitting, an information card on existing government-provided support options (e.g., MyQuitBuddy App, iCanQuit App, link to Aboriginal Quitline webpage), as well as health promotion and Aboriginal merchandise (e.g., a hat, socks or beanie from Clothing the Gaps, a Victorian Aboriginal led and controlled, and majority Aboriginal owned, social enterprise). Participants will be asked whether they have received the posted package and adherence to the resources will be evaluated at each follow-up.
(2) Multiple offers of Nicotine Replacement Therapy (NRT): participants will be offered a 12-week course of combination NRT consistent with RACGP recommendations at baseline during the initial phone call post enrolment. Intervention check-ins will take place at 2, 6, and 10 weeks for all participants to allow for re-assessment of required strength and preferences regarding formulations of NRT. Available NRT will include 21mg nicotine patches and faster-acting oral NRT formulations (lozenge, gum, inhalator) as combination NRT, consistent with RACGP smoking cessation guidelines. Participants who want to use NRT will have it mailed to their homes after each check-in time point.
(3) Multiple offers of behavioural counseling. A Research Assistant will explain that the most effective way to quit smoking is to combine a combination of NRT with support to manage cravings and triggers to smoke, which is provided by Aboriginal Quitline. All participants will be offered a call from Aboriginal Quitline (proactive referral) at each follow-up contact starting from the initial phone call post enrolment and Quitline will call those who consent. Quitline will encourage and monitor the use of supplied NRT, explore any barriers to use, and will check for correct techniques to help maximise the effectiveness of the supplied products. Quitline will also provide written and other resources as required and can link participants up with local support groups if requested.

Outcomes
Primary outcome [1] 335322 0
Smoking cessation

This will be measured by self-reported 7-day point-prevalence abstinence at 6 months follow-up. Participants will be asked whether they have smoked, even a puff, in the last 7 days at each follow-up time point in line with recommendations from the Society for Research in Nicotine and Tobacco.

6 months post-enrollment (refers to data collection at 6 months for each participant from their enrollment date)
Primary outcome [2] 335323 0
Smoking cessation

This will be measured by self-reported 7-day point-prevalence abstinence at 3 months follow-up. Participants will be asked whether they have smoked, even a puff, in the last 7 days at each follow-up time point in line with recommendations from the Society for Research in Nicotine and Tobacco.

3 months post-enrollment (refers to data collection at 3 months for each participant from their enrollment date)
Secondary outcome [1] 423946 0
Participant recruitment

The number of self-referrals from advertisements and the number of self-referring individuals who meet eligibility criteria will be recorded by the Research Assistant to give an indication of intervention reach.
Timepoint [1] 423946 0
Baseline (refers to the initial data collection point for each participant upon their enrollment into the study)
Secondary outcome [2] 423947 0
Participant uptake and adherence to intervention components

Uptake of each of the offered smoking cessation support strategies included in the Quit Pack and adherence to combined NRT will be recorded at each follow-up time point. Apps: Participants will be asked at each follow-up point if they accessed the MyQuitBuddy or the iCanQuit Apps and for those that accessed, the frequency and duration of use will be recorded. Quitline: The Research Assistant will keep records of participant acceptance of Quitline referrals at baseline for all participants. NRT: The Research Assistant will keep records of participant acceptance of cNRT. At each follow-up, participants will be asked to self-report their use of mailed NRT. Uptake and adherence will be measured as a composite secondary outcome.
