we use the tools of SGA and NRS2002 to understand the nutritional status of Chinese Han inpatients during hospitalization and discharge, and to dynamically analyze the changes in the process of internal medicine and surgery in many general hospitals across Zhejiang Province.

5. Comprehensive evaluation tools at admission and discharge: subjective comprehensive nutritional assessment (SGA) and nutritional risk screening (NRS2002);
6. Description of nutritional support during hospitalization: no nutritional support, pure enteral nutrition support, pure parenteral nutrition support, enteral + parenteral nutrition support;
7. Clinical outcome indicators at discharge: 30-day hospitalization mortality, total complications, infection complications, length of stay, total medical expenses, etc.
