Evaluation of Nutrition Risk in Patients Over 65 Years of Age With Nontraumatic Acute Abdominal Syndrome

The objective of this study is to investigate the power of CRP/Albumin ratio, NRS-2002, mNUTRIC scores to predict nutritional needs and mortality in patients over 65 years of age diagnosed with acute abdominal syndrome in the emergency department and then transferred to the surgical intensive care unit.

CRP/Albumin ratio, APACHE II, SOFA, NRS-2002 and mNUTRIC scores were calculated. The analysis of the data was conducted in IBM SPSS Statistics Base 22.0 package program.

In the analytical evaluation made for nutritional needs, AUC value for mNUTRIC was found to be: 0,683, 95% CI 0,611-0,755, p < 0.001. It was found out that mortality of patients had a statistically significant and moderate correlation with mNUTRIC score (r = 0.537; p < 0.001). In the analytical evaluation made for mortality, mNUTRIC's AUC value (AUC: 0.808, 95% CI 0.736-0.880, p < 0.001) was found to be the highest. When the cut-off value determined to predict mortality was taken as 3.5 for mNUTRIC score, sensitivity was 75.9% and specificity was 69.4%.

The evaluation of the risk of malnutrition through nutritional risk tools in intensive care patients over 65 years of age with acute abdominal syndrome can also predict nutritional needs in the early period besides mortality. Based on our data, the fact that mNUTRIC score cut-off value in older patients hospitalized in intensive care is 3.5 and higher may be a predictor for ICU mortality.
