Parenteral nutrition: can outcomes be improved?

This article explores parenteral nutrition (PN) not only as a therapy but also as a system of care, highlighting the potential "evidence gaps" in guidelines for PN use. The importance of interdisciplinary nutrition care, error reporting, and data-driven practice changes on improving PN therapy is emphasized. Finally, the American Society for Parenteral and Enteral Nutrition's current and future role in advancing the science, practice, and safety of PN is reviewed.
