COVID-19 outcomes in people with diabetes in Wales: a secondary analysis of the ABCD audit
Keywords:COVID-19, diabetes, Wales, United Kingdom
Background: People with diabetes and coronavirus disease 2019 (COVID-19) have a significantly greater risk of death and/or intensive care unit (ICU) admission. The Association of British Clinical Diabetologists (ABCD) recently audited outcomes for people hospitalised in the UK with diabetes and COVID-19.
Methods: The ABCD COVID-19 and diabetes audit was a retrospective audit of patients admitted to UK hospitals with diabetes and COVID-19 between March and December 2020. Data related to patients admitted in Wales were compared with patients admitted in England and Scotland.
Results: In Wales, 40/82 (48.7%) patients with diabetes had COVID-19-related mortality compared with 1,149/2,916 (39.1%) in the UK group (p=0.08). The Welsh cohort were more likely to be Caucasian, have a higher body mass index and HbA1c, be diagnosed with diabetic retinopathy and prescribed a sodium-glucose co-transporter 2 inhibitor or insulin than those in England and Scotland. Patients admitted to the ICU in Wales were more likely to be male and have type 2 diabetes.
Conclusions: Patients admitted to hospital with diabetes and COVID-19 in Wales had a poorer outcome compared with England and Scotland. This disparity may reflect social inequality, differences in cardiovascular risk factors and/or differences in diabetes medications between hospitalised patients in Wales and the UK.
