Sepsis is a common disease seen in critically ill patients. Many patients with sepsis are unable to provide nutrition for themselves, and therefore initiating artificial nutrition has become part of routine care for these patients. ⋯ The best recommendations have to be extrapolated from studies in heterogeneous populations of critically ill patients or in those with syndromes such as acute lung injury or acute respiratory distress syndrome (ARDS) where sepsis is a common predisposing etiology. In this review, we summarize pertinent studies that inform clinical practice on providing artificial nutrition to critically ill patients with severe sepsis and make recommendations as to how these studies influence clinical care of these patients.

Nutrition therapy protocols seek to correlate current scientific knowledge with clinical practice by converting evidence-based efficacy data into clinical effectiveness. Implementing nutrition therapy protocols should be justified by their impact on clinical outcomes. Thus, our objective was to analyze studies that verified the effect of implementing protocols for enteral nutrition (EN) in critically ill patients who are mechanically ventilated. We investigated initiation of nutrition therapy, time until nutrition requirements are met, optimization of protein and energy intake, duration of mechanical ventilation, length of hospital and intensive care unit stay, mortality, and adherence to protocols. ⋯ Our analysis of previously published studies indicates that implementing a nutrition therapy protocol can lead to optimization of various aspects of nutrition practice. Further studies that take into consideration local facilitating (as well as hindering) factors may reveal the impact of strategic EN protocols on clinical outcomes.
