Abstract

Aims/Introduction:

We aimed to identify factors – glycemic control, reactive inflammatory biomarkers or vital signs – associated with mortality in diabetic patients admitted to hospital for various infections (non-intensive care unit).

Materials and Methods:

We retrospectively analyzed the cases of 620 diabetic patients admitted to hospital for various infections (non-intensive care unit) who underwent glucose monitoring >3 times per day. We extracted data regarding reactive inflammatory biomarkers and vital signs recorded on day 1 of hospital stay, and data on bacteremia and hypoglycemia status, glycemic variability (GV; coefficient of variation and standard deviation) and mean glucose concentrations during the entire hospital stay. Univariate and stepwise multivariate logistic regression analyses were carried out to determine the association between these factors and mortality.

Results:

The mortality rate was 10.1%. Reactive inflammatory biomarkers, vital signs and bacteremia were not associated with mortality. According to the results of the adjusted analysis, hypoglycemia showed a significant positive association with mortality, increasing death risk by 266% (odds ratio [OR] 2.66, 95% confidence interval [95% CI] 1.22–5.83; P = 0.0006). High coefficient of variation and standard deviation values were significantly associated with increased mortality, increasing death risk by 18% (OR 1.18, 95% CI 1.01–1.38; P = 0.03) and 9% (OR 1.09, 95% CI 1.01–1.18; P = 0.03), respectively. Mean glucose concentrations were also significantly associated with mortality, increasing death risk by 5% (OR 1.05, 95% CI 1.02–1.08; P = 0.0008).

Conclusions:

Glycemic indices (especially hypoglycemia and GV), rather than reactive inflammatory biomarkers or vital signs, were associated with mortality in non-intensive care unit diabetes mellitus patients with infections.

We aimed to identify factors - glycemic control, reactive inflammatory biomarkers, or vital signs - associated with mortality in diabetic patients admitted in hospital for various infections (non-ICU). Glycemic indices (especially hypoglycemia and GV), rather than reactive inflammatory biomarkers or vital signs, were associated with mortality in non-ICU diabetes mellitus patients with infections.
