BackgroundNutritional status has been proven to be associated with poor outcomes in mechanically ventilated patients in intensive care units (ICU). Nutritional assessment has been assessed using different tools. Few data are available on the validity of the modified Nutrition Risk Assessment Tool for Critically Ill (mNUTRIC) score in ICU patients receiving mechanical ventilation (MV).AimThis study aimed to assess prognostic performance of the mNUTRIC score for discriminative abilities for 30-day mortality and prolonged MV.MethodsThis was a multi-centre retrospective study that included 737 mechanically ventilated patients using secondary data analysis. Data were collected on variables required to calculate mNUTRIC score. Patients with a mNUTRIC score ≥5 were considered at nutritional risk. Predictive performance of the mNUTRIC was assessed for discriminative abilities for Acute Physiology and Chronic Health Evaluation II at baseline, mortality in 42 days of follow-up and outcomes related to MV.ResultsA total of 737 patients on MV met the inclusion criteria. The majority (57.1%) of patients were male. The mean age of the participants was 62.1±18 years. Of all patients, 482 (58%) were at high nutritional risk (mNUTRIC score ≥5). Median ventilator days were 3 (±7.2) days and 72 (±174) hours. The overall mortality rate was 78.8% (n=652), and weaning failure was 79.8% (n=660).ConclusionsThis study showed new evidence on the validity of the mNUTRIC as a tool for assessing nutritional risk in an ICU population in Jordan. The mNUTRIC score obtained from the current retrospective data suggests that the use of the tool can truly identify and diagnose critically ill patients with malnutrition.
