Adequacy of intake of prescribed caloric and protein and reduction of mortality in critically ill patients with body mass indices below 30

Abstract Objective Although the provision of nutrition helps minimize adverse outcomes in most patients in intensive care units (ICUs), little is known about the relative effect of energy and protein delivered on mortality in ICU patients with different BMIs. Methods We enrolled 1693 patients admitted to a medical center ICU in Taiwan during 2005-2011, subcategorizing them by BMI levels: 80%), moderately adequate (60-80%) and inadequate ( Results Mean DEI was 1237 kcal/day and DPI 47 g protein/day. Analyzed separately in our multiple regression models, moderately and highly adequate DEI(p for trends=0.003-0.026) and DPI (p for trends=0.001-0.004) were both significantly correlated with reduced mortality in patients with BMIs Conclusion Although the adequacy of delivery of prescribed DEI or DPI dosages appeared to be important for reduced risks of mortality in ICU patients with BMIs
