Modified NUTRIC score: a predictor for mortality in patients with septic shock-a single center retrospective study

Objective: to evaluate the modified NUTRIC score in identifying nutritional risk patients and predicting mortality in septic shock patients. Methods A retrospective study was performed with septic shock patients admitted to the intensive care unit (ICU) from January 2018 to December 2019. A receiver operating characteristic (ROC) curve was used to identify the performance of the instruments to predict mortality. Results Among the patients, 46 patients were non-survivors and 78 were survivors. The median mNUTRIC score was 5.41±1.69 vs 4.29±1.58(P<0.0001). 28-day mortality increased with higher modified NUTRIC score. In the ROC curve of mNUTRIC score, the best cut-off point was at 4. It was identified for our sample, showing the best parameters of both sensitivity and specificity for the prediction of mortality 28 days after ICU admission. The area under the curves (AUCs) of the mNUTRIC score for predicting 28-day mortality was 0.664(95%CI:0.574, 0.746). Conclusions The modified NUTRIC score was a good nutritional risk assessment tool for septic shock patients. mNUTRIC score showed a good performance for the prediction of 28-day mortality. A new cutoff value was identified for septic shock patients.
