Multidisciplinary nutritional support team and mortality in critically ill patients with acute respiratory distress syndrome

Background: A careful approach is required when providing nutritional support to patients with acute respiratory distress syndrome (ARDS). This study investigated whether implementing a multidisciplinary nutritional support team (NST) is associated with improved survival outcomes in patients with ARDS. Methods: In a nationwide population-based cohort study, all adult patients admitted to the intensive care unit (ICU) in South Korea with a primary diagnosis of ARDS from January 1, 2017, to December 31, 2021, were included. The NST comprised four professionals (physicians, full-time nurses, full-time pharmacists, and full-time clinical dietitians). Patients admitted to ICUs with and without the NST system were allocated to the NST and non-NST groups, respectively. Results: The analysis comprised a total of 15,555 patients with ARDS. Among them, 6615 (42.5%) were in the NST group, and 8940 (57.5%) were in the non-NST group. After adjusting for covariates in the multivariable logistic regression, the NST group showed a 19% lower 30-day mortality than the non-NST group (odds ratio: 0.81, 95% confidence interval: 0.75-0.87, p < .001). Furthermore, after adjusting for covariates in multivariable Cox regression, the NST group showed a 12% lower 1-year all-cause mortality than the non-NST group (hazard ratio: 0.88, 95% confidence interval: 0.85-0.92, p < .001). Conclusions: NST implementation was associated with enhanced 30-day and 1-year survival rates in patients with ARDS. These findings indicate that nutritional support provided by the NST may influence the survival outcomes of patients with ARDS in the ICU.
