Breast and bowel screening evaluation

Centre for Cancer Prevention

Funding Body:  Barts Health NHS Trust

Principal Investigator:  Professor Stephen Duffy,


We are undertaking two RCTs for the NHSBSP with the aim of increasing breast screening uptake.

The first study is investigating whether a reminder letter sent shortly before a scheduled breast screening appointment increases population uptake and is value for money. It well underway in three screening centres in the UK and the first data is expected around the New Year.

The second study aims to estimate the difference in overall attendance rate between non-attenders sent a second timed appointment letter or an open letter for them to make an appointment themselves. This study is starting shortly.
