Recommendations for specialized nutritional-metabolic management of the critical patient: introduction, methodology and list of recommendations. Metabolism and Nutrition Working Group of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC).

Abstract The Metabolism and Nutrition Working Group of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) has reviewed and updated the recommendations for specialized nutritional and metabolic support in critically ill patients published by the Group in 2011, with the primary aim of helping decision making in daily clinical practice. The recommendations have been formulated by an expert panel with broad experience in nutritional and metabolic support in critically ill patients, and were drafted between March 2016 and February 2019. A level of evidence has been provided for each of the recommendations, based on the GRADE methodology (Grading of Recommendations Assessment, Development and Evaluation Working Group). A grade of recommendation has also been produced, taking into account the clinical impact of the recommendation, regardless of the level of evidence established by the GRADE scale.
