Abstract:

The Chinese Society of Critical Care Medicine (CSCCM) has developed the clinical practice guidelines of nutrition assessment and monitoring for patients in adult intensive care unit (ICU) of China. This guideline focuses on nutrition assessment and metabolic monitoring to achieve the optimal and individualized nutrition therapy for critical ill patients. This guideline was made by experts in critical care medicine and evidence-based medicine methodology and was developed after a thorough system review and 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 review by expert groups in critical care medicine, parenteral and enteral nutrition, and surgery. The recommendations are based on the currently available evidence and cover several key fields, including nutrition risk 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 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 to 5 years.
