Abstract

Background: Limited data are available regarding the association between glucose levels variability (GV) and outcomes of patients hospitalized with acute infectious diseases. Aim: To determine the association between GV and bacteremia, length of stay (LOS) and mortality. Methods: A retrospective study of patients hospitalized in departments of medicine with respiratory tract, urinary tract and skin and soft tissue infections during 201117. GV was assessed by the coefficient of variation (CV) of glucose levels during hospitalization and was divided into tertiles (CV16%, 1729%,>29%). LOS, bacteremia rates and all-cause mortality (30 days, 90 days and after 5 years) were evaluated for the patients with and without DM according the three GV categories Results: The study consisted of 1485 patients, 838 (56%) were diabetic. There was no significant association between GV and LOS. Bacteremia rates were higher in the upper GV tertile compared with the lower one (6% vs. 2%, P0.007). Mid and upper tertiles compared with the lower one were significantly associated with increased 30-day mortality (13% vs. 5%, P0.005; and 40% vs. 5%, P0.002, respectively). A decreased 5 years survival was observed for both diabetic and non-diabetic patients in the mid and upper GV tertiles [adjusted HRs 0.8 (95% CI, 0.61.04) and 0.6 (95% CI, 0.50.9) in diabetic patients and 0.7 (95% CI, 0.50.9) and 0.5 (95% CI, 0.30.7) in the non-diabetic ones]. Conclusion: In diabetic and non-diabetic patients, hospitalized in non-ICU setting with acute infectious diseases, increased GV is associated with increased risk of bacteremia, short and long-term mortality.
