Leading Evidence & Insight

Group of people in a workshop talking around a table.

We hear from thousands of people every month so we know we can tell powerful stories about your lives and what needs to change, backed by facts and statistics. But we also know that we are not reaching every part of our community so cannot reflect the full range of experiences. We are making it our mission to fully understand your experience so we can fight for everyone affected by Crohn’s and Colitis.

The evidence and insight programme will identify gaps in the current knowledge of Crohn’s and Colitis and address them. Our aim is to understand the experiences of all those affected by Crohn’s and Colitis, including those from underserved groups.

By ‘evidence’ we mean facts and information drawn from research, data analysis and evaluation. ‘Insight’ is where evidence is applied in real-life situations to gain more knowledge from people’s lived experiences.

Currently we are funding research to strengthen our evidence and insight into areas such as:

  • Who lives with Crohn’s and Colitis in the UK - As you may already know, earlier this year we received the results from a study we commissioned that showed the number of people living with Crohn’s Disease or Ulcerative Colitis in the UK has been vastly underestimated. Read more here. Next, we need to explore in more depth how Crohn’s and Colitis is shaped by factors such as age, gender, ethnicity, location and socioeconomic factors. This work will deepen our understanding of different lived experiences of Crohn’s and Colitis across the UK and lay the foundations for our future work.
  • Earlier diagnosis – We’ve completed an evidence review to give us a better understanding of where and why diagnostic delays occur and what has worked to tackle this in other conditions. We’re also in the process of interviewing a wide range of people who have experienced delays in their diagnosis to delve in more depth into their experiences and identify where barriers have occurred and how these can be overcome.
  • The cost of IBD – We want to know the true cost of IBD to individuals, the NHS and wider society. This project will examine if delays in diagnosis impacts the costs. If you are interested in applying to deliver this project, click here for more information.
  • Improving diversity in research – We’ve recently partnered with ClearView Research to gather evidence that will help us better understand the barriers to getting involved with research. We're especially interested in issues affecting people with Crohn’s and Colitis from different racial, ethnic and minority backgrounds. We’ll use this evidence to implement change.

By actively expanding our evidence and insight base, we are leading what is known about Crohn’s and Colitis in the UK.

Understanding diagnostic delays in Crohn’s and Colitis: an evidence review for Crohn’s & Colitis UK

Crohn's & Colitis UK have commissioned an evidence review to develop an understanding of where and why diagnostic delays occur in Crohn’s and Colitis and to gain insights from how delays in diagnosis have been tackled in other comparative diseases which might help to address diagnostic delay issues in IBD.
