Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Individuals from intervention General Practices who opt in to the study will be given a password, allowing them to access the ‘Family History Website’ tool. This online tool will collect information about their family history of colorectal cancer and encourage discussion with their relatives so that they can gather accurate information. Upon completion of the questionnaire, individuals will be assigned to a NHMRC designated risk category for developing CRC, which will be accompanied by the appropriate screening recommendations, with a personalised summary of their information. This information will be accessible to their GP via a shared access facility, and participants will be encouraged to discuss their results with their GP within the following consultation. The completion of the family history website and GP consultation thereafter, is known as Assessment 1 at time = 0. Participants will be followed up 12 months after their completion of the ‘Family History Website’, where they will be required to self report their five year screening behaviour; while their GP’s will complete a file audit and a survey about the utility of the ‘Family History Website’ tool in addition to their knowledge about CRC risk and screening guidelines. This will be known as assessment 2 at time =1

Prevention
Comparator / control treatment
Individuals from control practices will not be contacted or recruited until time =1, 12 months after the intervention group opt in to the study. At time=1, control participants will be recruited and their self report five year screening behaviour will be recorded, along with a GP file audit, their known family history and demographic information such as age, gender and educational attainment. Consequently, screening behaviour will be measured during the same time for both the intervention and control groups. GP’s from control practices will also be surveyed about their knowledge about CRC risk and screening guidelines. Following the reporting of screening behaviour and the GP survey at time=1, the control group and their GP’s will be able to access ‘Family History Website’ tool if they so wish.

Outcomes
Primary outcome [1] 266449 0
Outcome Aim: Risk appropriate screening uptake as measured by the participants' five year screening behaviour in relation to their colorectal cancer risk category

Five year screening behaviour- All participants will have their five year screening behaviour recorded at time=1 by self report
Timepoint [1] 266449 0
12 to 18 months after randomisation, t=1
Primary outcome [2] 266450 0
Colorectal cancer risk category- Intervention practice participants will receive a CRC risk category after completing the 'Family History Website' tool., at some time within the 12 month time period t=0. However, participants from control practices will asked about their 'known family history' at time=1, and will not be allowed access to the 'Family History Website' tool, until after that information is collected.
Timepoint [2] 266450 0
Within 12 months of the intervention , t=0 for the intervention group and one year after randomisation, t=1 for the control group
Secondary outcome [1] 273799 0
GP audit and survey- The GP audit will serve to validate self reported screening behaviour for both groups. The GP survey will collect valuable primary care feedback regarding the utility of the family history website (intervention group only), and gauge GP's general awareness of family history risks and current screening recommendations. Additionally, practice demographic information and related characteristics will be recorded. This will also serve as a form of continuing education for GP's and they will be eligible to receive QA and CME points for participating in the study.
Timepoint [1] 273799 0
12 to 18 months after randomisation, t=1.
Secondary outcome [2] 273800 0
Participants demographic information- Demographic information from participants will collected from intervention and control participants. This information will include socio-economic (educational attainment and employment status), gender, family size, age and ethnicity status.
Timepoint [2] 273800 0
This will be collected when participants self report their five year screening behaviour 12 to 18 months after randomisation, t=1.

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)
This is a random clustered trial, and recruitment will be randomised by practice not participants. General Practices will be sent a letter of invitation. If they agree to participate they will be randomly divided between control and intervention practices. Practices will be expected to be involved in the study at some time over a 12 to 18 month period and will be blind to allocation. Participants will receive an invitation of participation in the study, from their GP practice. Intervention practices will be contacted at t=0 to send out letters of invitation and control practices 12 to 18 months later. Allocation is not concealed from the researchers as this will be required for follow- up.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
GP Practices that opt in to the study will be entered into a database and assigned to intervention or controlled group using a random sequence generator.
Masking / blinding
