Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There are two intervention arms: Intervention arm 1 is an 'SMS-only' sent from general practice to patients, Intervention arm 2 is an 'SMS-bundle' - an SMS with additional video material sent from general practice to patients. The study is a cluster randomised controlled trial with the cluster unit being individual general practices. The intervention will be sent from general practices using an SMS service 'GoShare' depending on the cluster that the general practice has been randomised into. The SMS-only/SMS-bundle will be sent to eligible patients two weeks prior to when their National Bowel Cancer Screening Program (NBCSP) kit is due to arrive. The participants will only be sent one SMS-only or SMS-bundle.
1. The SMS-only is sent from a patient's general practice is to prompt patients to do the NBCSP kit. The SMS contains a greeting and the patient's first name, general practice name and telephone number, a GP endorsement of the NBCSP and the option to 'opt-out' of receiving future SMS.
The wording in the SMS is: 'Hi [insert patient first name]. Your free bowel cancer screening kit will arrive in the post soon. [insert general practice name] strongly encourages you to do this test. Call us on [insert general practice telephone number] if you have any questions. Reply STOP to opt out'.
2. The SMS-bundle is the SMS as described above, but with an web link to a GP message with the general practice logo and endorsing the NBCSP, a video of relatable people talking about why it is important to do the kit (approx 30 seconds long), an instructional video on how to do the kit (approx 45 seconds long), and a link to more information about the NBCSP.
The wording is: 'Hi [insert patient first name]. Your free bowel cancer screening kit will arrive in the post soon. [insert general practice name] strongly encourages you to do this test. We also recommend you watch these videos [weblink to videos inserted here]. Call us on [insert general practice telephone number] if you have any questions. Reply STOP to opt out'.
The intervention will be conducted from general practice and run for 6 months.
The amount of people who opened the weblink and if they watched the videos will be recorded and we will follow up at a later time (not included in this protocol) with interviews with participants about whether or not they read the message etc. We have qualitative data for the previous pilot about the adherence to the intervention and we have modified the SMS-bundle accordingly - mainly making it shorter and modifying the content.

Early detection / Screening
Comparator / control treatment
General practices randomised into the control arm will not send SMS to eligible patients, but continue their standard 'usual care'. Usual care is defined as following the guidelines for bowel cancer screening as defined by the Royal Australian College of General Practitioner Red Book Guidelines for Preventive Activities in General Practice.
Control group
Active

Outcomes
Primary outcome [1] 333342 0
Primary outcome:
The primary outcome will be the difference in the proportion of patients who have a faecal occult blood test (FOBT) result recorded by the National Cancer Screening Register between the control arms and both interventions.
This will be analysed by sex, age and location.
Timepoint [1] 333342 0
The time point will be 4 months after the intervention phase is completed (SMS has been sent to patients). This decision was made in May 2024, after recruitment but before the intervention period began.
Secondary outcome [1] 416681 0
This is a composite secondary outcome to measure adherence. We will calculate the number of patients who "opt out" of receiving future SMS (Interventions 1 & 2), the number of times the web link in the SMS is 'clicked on' and opened, and the number of times each of the videos are 'clicked on' to view (Intervention 2 only) to determine the level of adherence and compliance with the intervention. The data will be provided by Healthily using their website analytics.
Timepoint [1] 416681 0
The time point will be 4 months after the intervention phase is completed (SMS has been sent to patients). This decision was made in May 2024, after recruitment but before the intervention period began.
Secondary outcome [2] 416682 0
Economic evaluation: We will use a calibrated and validated microsimulation platform designed to evaluate cost, benefits and harms of colorectal cancer screening. We will estimate the cost effectiveness of each SMS intervention and the long term bowel cancer incidence and mortality outcomes among patients in the trial. We will also estimate budget impacts on the health care costs and long term bowel cancer incidence and mortality reduction in the Australian population if the interventions was adopted and implemented nationwide.

Eligibility
Key inclusion criteria
General practice eligibility criteria:
• Practices have to be located either in Queensland or Victoria - we will randomise by remoteness using the Modified Monash Model to ensure all trial arms are equivalent (Metropolitan areas, regional centres, large, medium and small rural towns, and remote communities).
• Practices use electronic medical records (EMR) software compatible with and can host the NCSR (Best Practice, Medical Director 3/4).
• Have at least 2 full-time equivalent (FTE) GPs working in their general practice.
• Have a practice manager (or delegate) who is happy to champion the trial in the general practice throughout the time of the trial.
• Practices are willing to download the National Cancer Screening Register application onto their computer system.
• Practices agree for the researchers to train clinic staff to generate lists of eligible patients and populate these lists with the date the NBCSP kit is due in batches through a secure and encrypted process directly from the NCSR.
• All GPs agree to their eligible patients receiving the 'SMS only' or the 'SMS bundle' (randomisation happens after consent).
• Practices agree for the researchers to train practice staff to upload (once) the patient lists to the GoShare secure platform for automated SMS sending.
Patient inclusion criteria:
• Attend a participating general practice
• Aged between 49 and 60 years old who have been in touch with the practice three or more times in the previous two years.
• Due to receive a NBCSP kit during the time the intervention is being conducted
• Have not had a bowel cancer diagnosis

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation is at the general practice (cluster) level. Randomisation will be done "off-site" at a central administration site by a statistician blinded to the identity of all general practices. All researchers except for the trial coordinators and the trial lead will be blinded to the randomisation status of the general practices until the final analysis has been completed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will use a computer-generated allocation sequence, stratified into two groups by geographical remoteness using the Modified Monash Model (MMM) classifications 1-3 and 4-6 (7 includes very remote locations and will not be included) will be grouped together (1-3: metropolitan cities/regional, 4-6: rural/remote) with random permuted block sizes within each stratum. This will be done by the statistician who will be blinded to the identity of all the general practices.

Statistical methods / analysis
SMARTERscreen will require participation of 60 general practices with an average of 260 eligible patients to receive a NBCSP kit during the intervention phase (6 months) and coefficient of variation 0.76 to allow for variation of patient numbers across general practices. This will be sufficient to detect the minimally clinically meaningful difference of 10% absolute increase in participation in the NBCSP between each of the intervention arms and the control arm (44% vs 34%) and to detect a smaller difference of 7.5% between the two interventions arms. A national 10% increase in screening participation would prevent 24,300 bowel cancers, 16,800 deaths and save the health budget $300 million over current screening levels.

Logistical regression using general estimating equations with standard errors to allow for clustering by general practice will be used to test the difference between each intervention arm and the control arm. Estimates of the effect of the interventions will be reported as an odds ratio with 95% confidence interval and p value.

We will calculate the number of times the weblink in the SMS bundle is clicked on and the number of times each video is viewed. We will also calculate the number of times the patient opts-out of receiving future (SMS- only and SMS bundle)

We will provide estimates on budget impact on the health care cost and long term term bowel cancer incidence and mortality reduction in the Australian population if the intervention was adopted and implemented nation-wide. We will do this by using a calibrated and validated microsimulation platform designed to evaluated cost, benefits and harms of colorectal cancer screening.
