Bernhard M, Kramer A, Doll S, et al. - This study was undertaken to investigate the association between admission blood glucose levels and patient mortality during the management of nontraumatic critically ill patients in the emergency department (ED) to distinguish patients at higher risk. Researchers designed a prospective, single-center observational study in a German university ED including all adult patients admitted to the resuscitation room of the ED between September 1, 2014 and August 31, 2015. In this study, 532 patients were admitted to the resuscitation room during the study period. It was shown that abnormal admission blood glucose is correlated with a high in-hospital mortality. According to the findings, admission blood glucose is an inexpensive and rapidly available laboratory parameter that may predict mortality and help to distinguish critically ill patients at risk in a general nontraumatic critically ill ED patient cohort. The results demonstrated that the breakpoint for in-hospital mortality may be an admission blood glucose ≤ 100 and ≥ 272 mg/dL.
