Clinical practice guidelines for nutritional assessment and monitoring of adult ICU patients in China

The Chinese Society of Critical Care Medicine(CSCCM)has developed clinical practice guidelines for nutrition assessment and monitoring for patients in adult intensive care units(ICUs)in China.This guideline focuses on nutrition evaluation and metabolic monitoring to achieve optimal and personalized nutrition therapy for critically ill patients.This guideline was developed by experts in critical care medicine and evidence-based medicine methodology and was developed after a thorough review of the system and a summary of relevant trials or studies published from 2000 to July 2023.A total of 18 recommendations were formed and consensus was reached through discussions and reviews by expert groups in critical care medicine,parenteral and enteral nutrition,and surgery.The recommendations are based on currently available evidence and cover several key fields,including screening and assessment,evaluation and assessment of enteral feeding intolerance,metabolic and nutritional measurement and monitoring during nutrition therapy,and organ function evaluation related to nutrition supply.Each question was analyzed according to the Population,Intervention,Comparison,and Outcome(PICO)principle.In addition,interpretations were provided for four questions that did not reach a consensus but may have potential clinical and research value.The plan is to update this nutrition assessment and monitoring guideline using the international guideline update method within 3–5 years.
