Diabetes is a common condition that affects more than one in 20 people in the general population and about one in 5 people who are in hospital. Early in the Covid pandemic diabetes was found to be an important risk factor for being infected, being admitted to hospital and having severe illness (admission to an intensive care unit or dying in hospital). This project will investigate whether the increased risk has changed over time, taking other important factors (such as age) into account. Another aspect of this project is to check how well a diagnosis of diabetes is recorded in different health records by comparing information collected by GPs and hospitals. If we find that recording is reliable this will be extremely helpful to support quality improvement programmes in the health service and achieve better outcomes for people with diabetes.
