Brief summary

The study will evlaute if implementing a web based tool allowing consumers time to gather information about their family history of bowel (colorectal) cancer , (to be used in conjunction with GP triage), will reduce the proportion of average risk people having an unnecessary colonoscopy; while correctly indentifying and appropriately referring at-risk individuals to Familial Cancer Services and/or offering a colonoscopy. It aims to significantly reduce the public burden of bowel cancer by ensuring that the most effective screening can take place.

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
