Ted with mortality in elderly (66.42 ?6.47 vs 36.34 ?12.70, P = 0.000) whereas APACHE 11, MV days, Mean blood Glucose (MBG) were not Conclusions: For the similar APACHE 2 score, elderly patients have greater glycemic variability , which could have contributed to the increased mortality. Amongst the glycemic variability indices tested, GLI was found to be better predictor than MBG.References 1. Sub
