Effect of Registered Dietitian Nutritionist Order-Writing Privileges on Enteral Nutrition Administration in Selected Intensive Care Units.

BACKGROUND: Adequate nutrition is linked to improved patient outcomes during critical illness. Nutrition care is further enhanced by registered dietitian nutritionist (RDN) order-writing privileges, which improve the implementation of nutrition interventions. The purpose of this performance improvement project was to evaluate the effect of RDN order-writing privileges on enteral nutrition (EN) order compliance and nutrition delivery in selected intensive care units (ICUs) at a university-affiliated teaching hospital.

METHODS: Patients admitted to selected ICUs from January 23, 2018, to January 25, 2018, were screened for eligibility. Demographic and nutrition data were collected retrospectively from the electronic health record. Percent of energy and protein needs met were calculated. Data were compared with historical internal controls identified prior to RDN order-writing privileges.

RESULTS: Fifty adult patients (150 EN days) were included in data analysis, with 93 patients (279 EN days) included in historical data. Compared with historical data, cumulative EN order compliance increased by 17% and tube feed infusion rate compliance by 15% post-RDN order-writing privileges. Mean (± SD) protein needs delivered significantly increased from 72.1 ± 28.6% to 89.1 ± 24.8% after RDN order-writing implementation (P < 0.001).

CONCLUSIONS: RDN order-writing privileges improved EN order compliance and significantly improved protein delivery in selected ICUs. Future studies are recommended to confirm these results and determine if other variables besides protein delivery are statistically significant with a larger sample size.
