A recent large-scale study concludes that both type 1 and type 2 diabetes are associated with an increased risk of COVID-19-related in-hospital death. It finds that one-third of coronavirus-related deaths in hospitals in England are individuals with diabetes.
Diabetes and COVID-19
According to the authors, their study is “the largest COVID-19 related study, covering almost the entire population of England, and is the first study to investigate the relative and absolute risks of death in hospital with COVID-19 by type of diabetes, adjusting for key confounders.”
To investigate, the researchers used data from the National Diabetes Audit: an estimated 98% of doctor’s offices in England participated in this program, the purpose of which is to help monitor and improve diabetes services.
The scientists extracted information from the COVID Patient Notification System, which registers all hospital deaths related to COVID-19. They used data from March 1–May 11, 2020.
As part of the analysis, the authors adjusted their findings for factors that might influence the results, such as age, sex, deprivation, ethnicity, and existing health conditions.
Of the 61,414,470 people registered at a doctor’s office in the U.K., 263,830 individuals had a type 1 diabetes diagnosis, and 2,864,670 had a type 2 diabetes diagnosis. The authors write:
“There were 23,804 COVID-19 related deaths. One-third occurred in people with diabetes: 7,466 (31.4%) with type 2 and 365 (1.5%) with type 1 diabetes.”
After adjusting for age, sex, deprivation, ethnicity, and geographical region, the researchers found that, compared with individuals without diabetes, people with type 1 diabetes had 3.5 times the odds of dying in the hospital with COVID-19. Similarly, individuals with type 2 diabetes had 2.03 times the odds of dying in the hospital with COVID-19.
When the researchers adjusted the data to account for previous hospital admission with coronary heart disease, cerebrovascular disease, or heart failure, the odds changed to 2.86 and 1.81, respectively.
Overall, the authors conclude that “all types of diabetes are independently associated with a significant increased risk of in-hospital death with COVID-19.”
