Background: Malnutrition is common in mechanically ventilated critically ill patients and contributes to poor outcomes. This study evaluated its prevalence and associated factors in a medical critical care unit (MCCU).
Method: A retrospective study of adult mechanically ventilated patients admitted between May 2021 and July 2024. Nutritional status was assessed using NT 2013, with day-7 status used for outcome analysis. Logistic regression identified factors associated with malnutrition.
Result: Among 334 patients, malnutrition prevalence was 36.8% at admission and increased to 44.3% during hospitalization. Malnourished patients had lower BMI and higher severity scores (APACHE II, SAPS II, SOFA). They also experienced worse outcomes, including higher MCCU mortality (26.0% vs. 14.8%), higher in-hospital mortality (41.5% vs. 25.4%), longer mechanical ventilation, and longer hospital stays. These associations persisted in patients hospitalized ≥7 days. Independent factors associated with malnutrition were younger age (aOR 0.97) and higher APACHE II score (aOR 1.07).
Conclusion: Malnutrition is frequent and worsens during MCCU stay, and is linked to poorer clinical outcomes. Early assessment, close monitoring, and timely individualized nutritional support are essential.
