Abstract
During the current COVID-19 pandemic, several investigations have illustrated that the presence of hyperglycemia during hospitalization increases the probability of poor outcomes and death, but this risk appears to vary [...]
Context: Diabetes or hyperglycemia at admission are established risk factors for adverse outcomes during hospitalization for COVID-19, but the impact of prior glycemic control is not clear. Objective: We aimed to examine the associations between admission variables, including glycemic gap, and adverse clinical outcomes in patients hospitalized with COVID-19 infection. Methods: We examined the relationship between clinical predictors, including acute and chronic glycemia, and clinical outcomes, including intensive care unit (ICU) admission, mechanical ventilation (MV), and mortality among 1786 individuals with diabetes or hyperglycemia (glucose > 10 mmol/L twice in 24 hours) who were admitted from March 2020 through February 2021 with COVID-19 infection at 5 university hospitals in the eastern United States. Results: The cohort was 51.3% male, 53.3% White, 18.8% Black, 29.0% Hispanic, with age = 65.6 [+ or -] 14.4 years, BMI = 31.5 [+ or -] 7.9 kg/[m.sup.2], glucose = 12.0 [+ or -] 7.5 mmol/L [216 [+ or -] 135 mg/dL], and Hb[A.sub.1c] = 8.07% [+ or -] 2.25%. During hospitalization, 38.9% were admitted to the ICU, 22.9% received MV, and 10.6% died. Age (P < 0.001) and admission glucose (P = 0.014) but not Hb[A.sub.1c] were associated with increased risk of mortality. Glycemic gap, defined as admission glucose minus estimated average glucose based on Hb[A.sub.1c], was a stronger predictor of mortality than either admission glucose or Hb[A.sub.1c] alone (OR = 1.040 [95% CI: 1.019, 1.061] per mmol/L, P Conclusion: Relative hyperglycemia, as measured by the admission glycemic gap, is an important marker of mortality risk in COVID-19.
