Fasting blood glucose (FBG) ≥7.0 mmol/l at admission is an independent predictor for 28-day mortality in patients with COVID-19 without previous diagnosis of diabetes. Glycaemic testing and control are important to all COVID-19 patients even where they have no pre-existing diabetes, as most COVID-19 patients are prone to glucose metabolic disorders.

605 COVID-19 patients were enrolled, including 114 who died in hospital.

Multivariable Cox regression analysis showed that age, CRB-65 score 1–2, CRB-65 score 3–4 and FBG ≥7.0 mmol/l were independent predictors for 28-day mortality.

The OR for 28-day in-hospital complications in those with FBG ≥7.0 mmol/l and 6.1–6.9 mmol/l vs <6.1 mmol/l was 3.99 or 2.61, respectively.
