The CRISP (Colorectal cancer RISk Prediction tool) trial: providing personalised advice about bowel cancer screening in primary care..

The CRISP study: trialing the use of a web-based colorectal cancer risk assessment tool with primary care patients as a 'nurse-led' intervention to determine the feasibility of using the method for a larger trial.

Brief summary

This research is aiming to test an intervention led by the practice nurse in general practice to discuss people's risk of bowel cancer and screening tests to diagnose it early. Who is it for? You may be eligible to join this study if you are a primary care patient aged between 50 and 74 years who has an appointment with a general practitioner (GP) who is participating in this study. Anyone who has had a previous colorectal cancer diagnosis will not be eligible. Study details: Participants in this study will be randomly (by chance) allocated to one of two groups. Participants in one group will continue to receive the usual care in the primary care clinic. Participants in the other group will go through a web-based colorectal cancer risk assessment with the practice nurse, who will then provide risk output and screening advice which can be discussed with their GP. Our primary aim is to determine how feasible the implementation of this tool is. The results of this feasibility study will assist in the design of a future Australian wide study before it is used more widely in practice. The research is part of a larger body of research: the 'NHMRC Centre for Research Excellence for Reducing the Burden of Colorectal Cancer by Optimising Screening: Evidence to Clinical Practice'.

Interventions

The intervention is a web based Colorectal cancer RISk Prediction tool (CRISP) risk assessment tool utilising a risk model to provide patients with a personalised risk assessment and colorectal cancer screening advice based on their risk. Patients in the intervention group will be invited to complete the risk tool with a trained researcher prior to a consultation with their GP. The tool will take a maximum of 7 minutes and will be completed at baseline only. Participants will receive their risk of colorectal cancer and screening advice based on their risk which they will take with them into their consultation with their GP. All participants will also complete a paper based survey collecting information about cancer risk perception, worry and bowel cancer screening intention and behaviour at baseline, 1 month, 6 months and 12 months after recruitment. The follow up survey should take no more than 15 minutes to complete and will be sent through the post.
