Purpose: Parenteral nutrition (PN) is essential for the treatment of patients with malnutrition. The provision of central PN should be recommended by a nutrition support team (NST) made up of a team of experts, even in a newly established hospital. This study sought to evaluate the effectiveness of PN delivered by a multidisciplinary NST in a recently opened hospital. Methods: This was a retrospective study of the effectiveness of a central PN recommendation pop-up message by the electronic medical record (EMR) software to prompt physicians to either calculate the required calorie and protein intake or consult with the NST. The study period was divided into pre-NST and post-NST based on the time of recruitment of NST-dedicated personnel. Results: Patients in the 12-week pre-NST period (n=50) and 12-week post-NST period (n=74) were compared retrospectively. Baseline characteristics were not significantly different between the two groups, except for the median Acute Physiology and Chronic Health Evaluation II score (pre-NST group, 8 [interquartile range, IQR 5–15.5] vs. post-NST group, 15 [IQR 9–24], P=0.012) of the 45 patients total admitted to the intensive care unit. The percentage of patients for whom physicians requested a consultation with the NST for central PN was significantly higher in the post-NST group (52.0% vs. 75.7%, P=0.011). There was no significant difference in achievement of nutrition targets or mortality. Conclusion: Building a multidisciplinary NST may increase awareness of nutritional status and affect the behavior of physicians in recently-opened hospitals.
