Multiple studies have shown a negative association between hyperglycemia and COVID-19 outcomes. Patients with diabetes have been shown to develop more severe symptoms and have rapid progression of the disease. One study found that among US patients hospitalized with COVID-19, the in-hospital death rate for those with diabetes, those with an A1c of 6.5% or higher, and those with hyperglycemia throughout their stay was 29% — a figure over four times higher than that for patients without diabetes or hyperglycemia. In addition, another study suggests that known diabetes was substantially more prevalent among intensive care unit (ICU) patients compared with non-ICU patients. Conversely, well-controlled glucose levels in patients with diabetes and COVID-19 appear to be associated with significant reductions in adverse outcomes and death. Even among patients with COVID-19 who do not have a prior diabetes diagnosis, hyperglycemia is an independent predictor of mortality.
