Admission glycemia and inhospital or long term mortality in patients without acute life-threatening conditions

Abstract

INTRODUCTION. Carbohydrate metabolism disorders are important risk factors of atherosclerosis development. Patients with admission hyperglycemia (AG), irrespective of diabetes coexistence, have a higher inhospital mortality rate in comparison to people with normal glucose level. Nowadays there are few papers refer to admission glucose effect on mortality in patients hospitalized due to other reasons than acute life-threatening conditions.
MATERIAL AND METHODS. The study group consisted with 4944 patients admitted to the Endocrinology and Diabetology Department CM UMK in Bydgoszcz. Analyzed people were divided into 3 groups according to presence or absence of the glucose metabolism disorders. The effect of admission glycemia on inhospital and 2 years mortality was evaluated.
RESULTS. In patients with newly diagnosed glucose metabolism disorders (group II) the highest AG - 15.2 mmol/l (273.6 mg/dl) was found. The lowest value of AG - 5.9 mmol/l (105.7 mg/dl) was observed in people without metabolic disorders (III). In patients with diabetes AG was 12.3 mmol/l (221.1 mg/dl) and was significantly different in comparison to groups II (p < 0.0001) and III (p < 0.0001). The highest percent of inhospital death (3.7%) was in III group. It was significantly higher than in patients with diabetes (I) (2.6%, p < 0.05). Among 870 examined patient 223 died: 94 (42%) in I group, 20 (9%) in II group and 109 (49%) in III group. After 2 years from the discharge there were no significantly differences in mortality rate between groups.
CONCLUSION. There was no correlation between admission glycemia and inhospital and long-term mortality in patients without acute life-threatening conditions.
