Nutritional support team intervention in surgical ICUs and its effect on nutrition delivery and quality in critically ill patients.

ABSTRACT

RATIONAL Critically ill surgical patients pose one of the greatest challenges in achieving nutritional goals. Several published papers have demonstrated clear benefits when nutrition support (NS) is managed by a multidisciplinary nutrition support team (NST). We hypothesized that implementing a NST in a surgical intensive care unit (ICU) would increase the number of patients achieving their nutritional goals. MATERIAL AND METHOD: Multicenter "BEFORE & AFTER" study. In the BEFORE phase, an audit of the previous state of NS was conducted in three ICUs without a NST. INTERVENTION Implementation of a NST and protocol. In the AFTER phase, a new audit of NS was conducted. Continuous variables (presented as mean ± SD or median Q1-Q3) were tested using the t-test and Mann-Whitney U test. Categorical variables (presented as frequencies and percentages) were assessed using the chi-square test. A binomial logistic regression model was performed, with independent variables introduced using a stepwise forward method. A difference was considered to be significant with a two-sided P-value <0.05. Statistical analysis was conducted using IBM-SPSS 26. RESULTS: A total of 83 patients were included in the BEFORE phase, and 85 in the AFTER phase. The latter group showed a higher frequency of nutritional risk and malnutrition (SGA B+C odds ratio 2.314, 95% CI 1.164-4.600). Laparoscopy was more frequently utilized as a surgical technique in the AFTER phase. No differences were observed in ICU and hospital LOS or 90 days' survival rates. Two variables remained independent factors to predict NS achievement NST implementation (odds ratio 3.582, 95% CI 1.733-7.404), and surgical technique (odds ratio 3.231, 95% CI 1.312-7.959). CONCLUSION: NST positively impacts the chance of achieving NS goals in critically ill surgical patients.
