The overall aim of this project is to develop and test a bespoke educational package to help people with severe mental illness and diabetes to manage their diabetes better. We also want to explore how this approach can be adapted for other long-term conditions.

Diabetes is more than twice as common in people with severe mental illness and has poorer outcomes than the general population. In England, around 44,000 people live with both conditions, (15% of all people with severe mental illness). Diabetes leads to complications including heart disease, stroke, eye and kidney disease and premature death, and contributes significantly to the lower life expectancy for people with severe mental illness.

To design the intervention, we will interview patients, carers and staff. Alongside this we will review the literature. This information will be used to develop self-management programmes for diabetes and chronic lung disease using workshops where patients and healthcare professionals jointly design the programmes. We will then test the diabetes self-management programme to check it is acceptable for patients and that it can be successfully delivered. Following this we will compare the diabetes self-management programme to usual care in a trial.
