Multiple studies have shown a negative association between hyperglycemia and COVID-19 outcomes. 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 is 29% — a figure over four times higher than that for patients without diabetes or hyperglycemia. 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.
