Summary
The English NHS Bowel Cancer Screening Programme (BCSP) offers biennial guaiac faecal occult blood testing (gFOBt). However, there is a socioeconomic gradient in participation and socioeconomically disadvantaged groups have worse colorectal cancer survival than more advantaged groups.
We co-designed two simple, zero cost interventions aimed at reducing this gradient and improving uptake overall: a GP endorsement to the screening invitation, and an enhanced reminder letter.
