Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a SMS personalised message from the general practice sent to the patient's smartphone with links to:
1. A message from the general practitioners (GPs) at the general practice (e.g. Hello. xxx
This is a health message from the GPs at xxx Medical Practice.
Your free bowel cancer screening kit will arrive in the post soon.
We strongly encourage you to do this test. If cancer is detected early over 90% of bowel cancers are successfully treated. We recommend that you watch the videos below.)

2. A video of a person talking about their positive experience of doing the National Bowel Cancer Screening Program (NBCSP) Immunochemical Faecal Occult Blood Test (IFOBT) test
3. A animated video demonstrating how to complete the test
4. Links to information from Cancer Council Australia
The SMS is sent from the general practice one month prior to patients 50th, 52nd, 54th, 56th, 58th and 60th birthdays. The intervention period is six months long, there will be 6 rounds of SMS sent during that time to any active patient due to receive their NBCSP kit. Patients will only receive one SMS. The number of patients due to be sent the SMS will be recorded in PEN CAT4 clinical audit software and the number of SMS sent is recorded on the GoShare Plus platform. Data, the number of patients due to receive the SMS and the number of SMS sent is recorded at the general practice. This data is collected by the project manager.

Outcomes
Primary outcome [1] 324564 0
The primary outcome will be the proportion of patients who complete the NBCSP after six months from the total number of eligible patients who are about to have their 50th, 52nd, 54th, 56th, 58th, or 60th birthdays. This outcome will be measured by the number of FOBT results sent to the general practice for patients in this age group. Aggregate data (number of FOBTs returned in each age group) will be collected from the electronic medical records.
Timepoint [1] 324564 0
From commencement of the 6 month intervention period to 6 months after completion of the intervention period.
Secondary outcome [1] 386409 0
Process measures will include whether the SMS is open and the number of times the links in the SMS are open. this is recorded on the Go Share Plus platform in the CAT4 clinical audit tool. tool. This aggregated data will be collected at the general practice.
Timepoint [1] 386409 0
From the commencement of the six month intervention to six months after the intervention period finishes.

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)
Each general practice is a cluster and will be randomised to either a control or intervention arm.
All general practices will be notified of their randomisation allocation due to the nature of the intervention. A computer generated allocation will be undertaken off site at a central location.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The unit of randomisation (cluster) is the general practice. Randomisation to either the control or intervention group will be done using a computer generated random sequence with 1:1 ratio. Randomisation will use a minimisation approach, maximising the balance across baseline variables. Baseline data will be collected from all general practices recruited to the trial prior to randomisation and we will stratify according by size of general practice (No of GP FTE) and location (regional city or regional town)

Statistical methods / analysis
We will recruit 20 general practices (10 intervention and 10 control ) in to this study. We will require 1400 patients (70 per general practice) to provide 80% power with two-sided 5% significance level to detect a 10% increase in National Bowel Cancer Screening Program participation in the intervention arm compared to the control arm (50% vs 40%). The estimates are based on average general practice population size, assuming an intra-cluster correlation of 0.008

Summary
Brief summary
This study is assessing whether a mobile phone SMS prompt will affect how many people choose to complete the National Bowel Cancer Screening Program (NBCSP) test among 50 to 60-year-old patients in Victoria.
Who is it for?
You may be eligible for this study if you are aged between 50 to 60 years, you are eligible to receive the free National Bowel Cancer Screening Program test kit, your GP has agreed to participate in the study and you have access to a smartphone.
Study details
Participants in this study will be randomly assigned to one of two groups. The first group will receive a single SMS message sent by their GP's practice one month prior to receiving their NBCSP test kit in the mail. The SMS message will include web links to a number of resources, including a message from their GP endorsing the free home test kit; a link to a narrative video of someone describing their positive experience of doing the test; a link to information about bowel cancer; and an animation showing how to do the test. The second group will not receive a SMS message but will still receive the NBCSP test kit in the mail. Participants in the second group will be able to discuss the test with their GP as part of their usual care.
It is hoped this research will determine whether an SMS prompt about completing the NBCSP test kit impacts on the number of people choosing to take up the screening test at home, which could increase early detection of bowel cancer.
