Introduction: Malnutrition leads to poor outcomes in surgical patients, leading to negative impact during the postoperative period. Nutrition Risk Screening (NRS) 2002 and Subjective Global Assessment (SGA) are novel tools to assess nutrition risk which have the potential to predict the postoperative complications in surgical patients. Aim: This study was carried out to determine the efficiency of the NRS 2002 and SGA in predicting postoperative complications. Materials and Methods: A prospective cohort study was conducted to assess the nutritional risk of patients aged 18 years and above who underwent elective abdominal surgery. NRS 2002 and SGA were used for nutritional screening. Univariate analysis was carried out to determine the relative risk (RR) of complications for each variable. Receiver operating characteristic (ROC) and area under curve (AUC) were plotted for NRS 2002 and SGA to identify the score for the former and grade for the latter that predicted complications postoperatively. The correlation of malnutrition with surgical outcomes was performed to determine their association. Results: A total of 320 patients were included in the study. Among the patients who underwent elective abdominal surgeries, 39.4% of the total number developed postoperative complications. The most prevalent were Grade 2 complications, which accounted for 69.1% of all such events. Postoperative complications were recorded in 75.5% of the patients identified as at risk by NRS 2002, with a RR of 5.3 (95% confidence interval [CI]: 3.7–7.6; P < 0.001). Complications were found among 68.3% of those who were malnourished by SGA, with a RR of 4.2 (95% CI: 3.0–6.0; P < 0.001). The ROC curve for NRS 2002 to determine the complications had an AUC of 0.80. A score of 3 was the optimal cutoff of NRS 2002 for predicting complications with a maximum sensitivity of 93.6%. Similarly, the ROC curve for SGA grades to determine complications had an AUC of 0.79. Grade B was the best cutoff, with a sensitivity of 77.0%. Conclusion: Patients with NRS 2002 scores higher than or equal to 3 and SGA Grades B and above had a higher incidence of postoperative complications in patients undergoing elective abdominal surgeries. Hence, NRS 2002 and SGA are reliable nutrition risk assessment tools for predicting postoperative outcomes.
