Gorshtein A, et al. - The relationship between admission blood
glucose (ABG) and mortality in older patients with or without diabetes
mellitus (DM) hospitalized for acute ischemic stroke (AIS) was assessed
in this study. The outcome of this study revealed that the elevated ABG
is related to increased long-term mortality in older patients without DM
hospitalized for AIS. Irrespective of DM status, elevated ABG was
related to increased in-hospital mortality and length of stay (LOS).
Methods
- For this study, they used observational data of 65 years or older patients, admitted for AIS between January 2011 and December 2013.
- In this study, ABG levels were classified to categories: ≤ 70 (low), 70-110 (normal), 111-140 (mildly elevated), 141-180 mg/dl (moderately elevated) and >180 mg/dl (markedly elevated).
- Main outcome was all-cause mortality at the end-of-follow-up.
Results
- Total of 854 patients were included in this study cohort.
- Among these 854 patients, 347 with (mean ± SD age 80 ± 8, 44% male), and 507 without DM (mean ± SD age 78 ± 8, 53% male).
- A significant interaction was noticed between DM, ABG and mortality at end-of-follow-up (p ≤ 0.05).
- In patients without DM there was a dose-dependent relationship between ABG category and mortality: adjusted hazard ratios (95% CI) compared to normal ABG were 1.8 (1.2-2.8), 2.9 (1.6-5.2) and 4.5 (2.1-9.7), respectively, for mildly, moderately and markedly elevated ABG.
- In patients with DM there was no relationship amongst ABG and mortality.
- No interaction was seen between DM, ABG and in-hospital mortality or length of stay (LOS).
- Irrespective of DM status, compared to normal ABG levels, increased ABG category was related to increased in-hospital mortality: adjusted odds ratios were 3.9 (1.1-13.4), 7.0 (1.8-28.1), and 20.3 (4.6-89.6) with mildly, moderately and markedly elevated ABG, respectively.
- Mean LOS was 6 ± 5, 7 ± 8, 8 ± 7, and 8 ± 8 days, respectively.
