Rationale: Preoperative malnutrition is common among gastrointestinal surgical patients and may influence postoperative recovery(1). This study aimed to evaluate whether nutritional status assessed by GLIM criteria and NRS 2002 predicts postoperative ICU discharge timing.
Methods: A prospective observational study was conducted among 86 patients undergoing major gastrointestinal surgery at Ward 20, National Hospital Kandy. Preoperative nutritional status was assessed using Global Leadership Initiative on Malnutrition (GLIM) criteria and Nutritional Risk Screening (NRS 2002). Patients were categorized into well-nourished vs malnourished (GLIM) and low-risk vs at-risk (NRS).
Postoperative ICU discharge timing was recorded and categorized as early (≤1 day) or delayed (>1 day) and chi-square tests were used.
Results: Among 86 patients, 63 (73.3%) were classified as malnourished by GLIM, while 73 (84.8%) were identified as at risk by NRS 2002.
GLIM malnourished group had a higher proportion of delayed ICU discharge compared to well-nourished patients. This association was statistically significant (χ² = 18.879, p = 0.016).
Similarly, at risk group by NRS demonstrated a prolonged ICU stay trend compared to low-risk patients, with a statistically significant association (χ² = 17.099, p = 0.029).
However, no clear linear relationship was observed across categories for either tool.
Conclusion: Preoperative malnutrition assessed by both GLIM and NRS 2002 was significantly associated with prolonged ICU stay following gastrointestinal surgery.
