Nutritional practices and impact of feeding adequacy on clinical outcomes in Chinese respiratory intensive care units patients: a prospective observational study (ORIENT study).

ABSTRACT:

Background

The current status of nutritional support for patients in Respiratory ICU across mainland China remains inadequately characterized. This multi-center study, conducted in RICUs, was designed to investigate nutritional practices in this specific patient population, focusing on initiation timing, energy/protein adequacy, and associations with clinical outcomes.

Methods

A prospective, observational study enrolled 1,026 patients (ICU stay >48 h) across 68 Chinese RICUs. We analyzed EN initiation rates (24 h/48 h), caloric/protein intake adequacy during the first 7 days, and outcomes via multivariable Cox regression.

Results

EN initiation occurred in 36.8% (24 h) and 43.4% (48 h) of patients. Excluding patients who could take oral food, the proportion of patients
