MELD-B ends at the end of November 2025. We hope to continue related work after that time depending on success in funding applications

AI stands for artificial intelligence, which is an umbrella term for computational techniques that carry out tasks in a way that mimics human intelligence. AI can also be thought of as a collection of methods for analysing data computationally. In MELD-B we are using AI to cluster people with similar patterns of burden and to analyse whether the timing and order of acquiring long-term conditions makes a difference to burden outcomes.

Work packages are a way of describing discrete components of a research study. They are often used in large research studies like MELD-B to break up the work into manageable areas, often using different methodologies. In MELD-B we have five work packages. For example Work Package one is working on a qualitative evidence syntheses and a Delphi consensus study, while work package three is working on AI analyses in big datasets.

MELD-B aims to understand more about the things that influence whether people develop multiple long-term conditions over their lifetime and the impact this has on their lives. The number of people with multiple long-term conditions is growing and the NHS and social care are struggling to cope with the growing demand. Prevention is an extremely important part of the solution to this and MELD-B hopes to identify the most important times in life, particularly early in life, when intervening might reduce the risk. This matters to the public because we can help to reduce the impact not only for ourselves, but for our children and grandchildren, as well as protecting the NHS and social care from being overwhelmed in the future.

MELD-B is interested in all types of long-term conditions. Information such as when they are diagnosed and the impact that specific combinations of conditions have on people over time will be studied carefully. As the research develops, combinations of specific conditions may emerge that become of particular interest due to their association with early life factors or due to the age they begin and the amount of impact they have on people’s lives.

Our active Patient and Public Involvement and Engagement (PPIE) team members are integral to the development of the research and success of the study. They help shape the things we focus on, how we communicate our findings to other people, and ensure we maximise our impact. Our PPIE members have helped develop videos, web content, policy briefs and attended conferences.

MELD-B is a collaboration between University of Southampton, Swansea University, University of Aberdeen, University of Glasgow, Kings College London, and Southampton City Council.
