Elderly patients with critical illness are more prone to have malnutrition and impaired immune function. How to improve the nutritional status of elderly patients with critical illness is important. At present, no consensus has been reached. In order to standardize the nutritional support strategies for elderly patients with critical illness, Chinese Geriatric Society and Critical Care Medicine Division of Chinese Geriatric Society took the lead in organizing experts in the fields of critical medicine, geriatrics, evidence-based medicine and clinical nutrition to summarize the new evidence in the field of enteral nutrition support for elderly patients with severe illness at home and abroad, and jointly formulated the Expert consensus on enteral nutrition support for elderly patients with critical illness in China (2022). In the consensus, the GRADE recommendation principle and improved Delphi method were adopted to formed 19 recommendations, including the timing, the dose and dosage of enteral nutrition, nutrition support-related complications, perioperative enteral nutrition support, to provide reference basis for enteral nutrition support treatment of elderly severe patients.
