Serial Body Composition Change for Risk Prediction and Nutritional Guide in Treating Patients With Sepsis

Serial Body Composition Change for Risk Prediction and Nutritional Guide in Treating Patients With Sepsis

To explore whether serial changes of data in body composition of patients with sepsis can help clinician to monitor prognosis.

The investigators will use the random number generator to divide the patients into two groups, the control group (with no nutritional intervention) and the intervention group (with nutritional intervention). The body composition data (of day 1, 3, 8) of the patients in the intervention group will be given to the dietitians for adjusting the diet formula according to the patient's body composition.The patients in control group also will undergo Bio-electrical Impedance Analysis (BIA) assessment, but not disclosed to the dietitian. The diet formula will be adjusted on the discretion of the dietitian caring for the septic patients based on clinical judgement.

Inclusion Criteria:

1. ICU patient
2. Clinical diagnosis of sepsis
