Bowel Cancer

Intervention

At age 60, and then every two years up to and including age 74, all patients registered with a GP and living in England (who have not explicitly opted out of screening) are sent an invitation letter with the screening information booklet by their local Hub. The gFOBt kit and instructions follow 8-10 days later. The individual is asked to collect samples from three separate bowel motions, and return the completed kit to the Hub in a pre-paid envelope for processing (see Figure 1). Repeat gFOBt kits are sent out following a ‘spoilt kit’, ‘technical failure’, or an ‘unclear result’. A reminder letter is sent after four weeks of non-response. The screening episode is closed if there has been no response within 13 weeks without another notification to the individual. The GP practices will receive a letter for their patients’ non-attendance. Following an abnormal result a referral is made to the local screening centre for further diagnostic investigations.

Intervention group:
People who are randomised to the intervention group will receive a text-message reminder in addition to the standard materials if they have not returned the test kit at eight weeks of their screening episode (i.e. three weeks after the ‘reminder letter’). The reminder text will include the name of the GP practice, GP endorsement, the purpose of the text-message, and guidance on where to get more information. The content of the text-message has been selected by a steering group involving patient representatives, GP Cancer Leads, Public Health England-Behavioural Insights Team and the BCSP London Hub.

Usual Care group:
Individuals in the control group will only receive the standard NHS CRC screening materials.
