Out of the 100 patients in the study, only 10% were initiated on PN during the ITU stay. All those who received PN were at higher risk of malnutrition as assessed by the malnutrition universal screening tool (MUST) score. The mean days of ITU stay was 3.4 prior to initiating parenteral nutrition. The mean ITU stay of PN group was 8.7 days vs 4.47 in the other group.
