Findings from the ASCEND study have been published in several journals including The Lancet. You can also access more information about this study and its findings on the UCL website.
Only one of the strategies tested, the enhanced reminder, increased the likelihood of people in the most deprived areas participating in screening. In addition, although it did not appear to particularly target more deprived areas, the GP practice endorsement modestly increased the likelihood that people in all areas would participate in screening, so this was also a positive finding.
It is hoped that these new invitation strategies will be implemented in the NHS Bowel Cancer Screening Programme as routine, to help reduce the risk of inequalities associated with screening and to improve overall participation.
