• The objective of this study was to understand the association of COVID-19 related mortality and patients with type 1 or type 2 diabetes in England.

• The data for this study utilized national data and was provided by the National Diabetes Audit.

• The weekly number of deaths of patients with either form of diabetes was recorded for the first 19 weeks of 2020 and the percentage difference in mortality rate from previous years was calculated.

• It was found that 464 people with type 1 diabetes and 10,525 people with type 2 diabetes had COVID-19 related deaths in this 19-week period.

• It was calculated that the mortality rate for the first 19 weeks of 2020 was higher by 50.9% in people with type 1 diabetes and 64.3% in people with type 2 diabetes.

• The study concluded that mortality rates rose sharply in both patients of type 1 and type 2 diabetes during the COVID-19 pandemic in England.

•This increased mortality was independently associated with diabetes.
