Interdisciplinary Discrepancies Between Parenteral Nutrition Macronutrient Prescribing and Recommendations: Is Body Mass Index a Factor?

Background: Formal nutrition training in medical schools and residencies is lacking and needed. Registered dietitians (RDs) are formally trained in nutrition support and considered experts in the nutrition field. Our purpose was to examine prescribing and recommending discrepancies of parenteral nutrition macronutrients between medical residents (MRs) and RDs and compare results with the ASPEN clinical care guidelines.
