Background: The American Society for Parenteral and Enteral Nutrition (ASPEN) parenteral nutrition (PN) safety consensus recommendations advise a comprehensive education program and competency assessment for all healthcare professionals involved in the care of patients receiving PN. The ASPEN-model papers provide guidance for designing PN competencies for prescribers, pharmacists, and pharmacy technicians. The purpose of this research was to evaluate the impact of a comprehensive educational program that aligns with the ASPEN model on PN competency, attitudes, and perceptions in a multidisciplinary healthcare professional audience. Methods: Dietitians, pharmacists, and physicians attended a 3-hour ASPEN model-based educational program focused on PN order writing and review. Matched preeducation and posteducation competency assessments were completed by attendees. Attitudes and perceptions were also assessed before and after the educational program using 5-point Likert scales. Results: Ninety-seven subjects were included in the analysis. The majority of attendees were dietitians (53.6%), followed by pharmacists (45.4%). Overall, multidisciplinary competency assessment scores improved by an average of 12.6% (preassessment average of 62.7%, postassessment average of 75.3%, P < 0.0001). Nine out of 10 statements regarding PN attitudes and perceptions significantly improved on the 5-point Likert scales (P < 0.05). Conclusion: A comprehensive PN educational program in alignment with the ASPEN model positively impacted multidisciplinary healthcare professional PN competency, attitudes, and perceptions. To optimize patient safety, local organizations and institutions should implement formalized training as outlined by the ASPEN model for healthcare professionals involved in the care of patients receiving PN.
