Abstract
BACKGROUND
Hyperglycemia is common in critically ill patients, even in those without diabetes, and it is known to increase mortality in patients with or without diabetes in the settings of acute myocardial infarction or acute stroke. However, the clinical effects of admission hyperglycemia are uncertain, and no data is available that compares the prognosis in a heterogenous group of critically ill patients. The aim of this study was to evaluate the effect of hyperglycemia on prognosis in a heterogenous group of critically ill patients with or without diabetes.
METHODS
The medical records of 858 consecutive adult patients admitted to a general intensive care unit (ICU) at a University Hospital over 21 months were reviewed. Patients with no records of blood glucose measurements and patients with normoglycemia during the first 3 days were excluded. The remaining 349 patients with hyperglycemia were divided into two groups according to a previous history of diabetes. Hyperglycemia was defined as a fasting blood glucose level of 140 mg/dl or more, or a random blood glucose level of 200 mg/dl or more on 2 or more determinations. The primary end-point of the study was ICU and in-hospital mortality, and its secondary end-point included length of stay in the ICU and hospital.
RESULTS
There were no significant differences in ICU mortality (17.6/19.0%), in-hospital mortality (24.5/24.3%), ICU length of stay (6.6 +/- 11.9/6.6 +/- 10.4 days), and hospital length of stay (11.4 +/- 29.0/12.8 +/- 24.3 days) between diabetics and nondiabetics.
CONCLUSIONS
Our results indicate that the effects of hyperglycemia on the prognosis of critically ill patients do not differ diabetics from nondiabetics.
