Sharif K, et al. - In this retrospective study, researchers determined the impact of in-hospital glucose control on length of stay, 30-days and 1-year mortality in patients admitted to the cardiac intensive care unit (CICU) of the Edith Wolfson Medical Centre between 01 January, 2010 and 31 December 2013. They used a multivariate logistic regression model and Cox regression to assess the association of glucose control with mortality, and to determine survival and 1-year mortality, respectively. Controlled glucose status was defined by glucose values between 71 and 200 mg/dL in more than 50% of a given patients. Those having concomitant diabetes mellitus were 370 of 2466 patients admitted to the CICU. Findings revealed shorter length of hospital stay, and lowered 30-day and 1-year mortality, in association with in-hospital control of glucose parameters. In critically ill patients, it is justifiable to make an effort to maintain glucose levels within reference ranges in order to reduce mortality.
