Introduction: The mNUTRIC score is a nutritional assessment tool to identify critically
ill patients with high nutritional risk who could benefit from nutritional interventions.
This study was conducted to validate the 28-day mortality prognostic performance
of the mNUTRIC score in a Malaysian intensive care unit (ICU). Methods: This was
a retrospective cohort study of adult patients who were consecutively admitted to
the ICU from January 2017 to December 2018 for >24 hours. Data were collected on
variables required to calculate the mNUTRIC score. Patients with mNUTRIC score
≥5 points were considered to be at high nutritional risk. Main outcome was 28-
day mortality from all causes; ICU length of stay (LOS) and prolonged mechanical
ventilation (MV) (>2 days) were secondary outcomes. Results: From a total of 432
admissions, 382 (88.4%) patients fulfilled the study criteria. Seventy-seven (20.2%)
of these patients were at high nutritional risk. They had longer mean ICU LOS
(7.1±7.5 days versus 4.2±4.0 days, p=0.001), greater proportion of prolonged MV
(57.1% versus 14.4%, p
