The OLIVE TREE: an electronic tool to guide initiation of parenteral nutrition in adult hospitalized patients with intestinal failure

Background: Parenteral nutrition (PN) is necessary to overcome malnutrition in hospitalized patients with acute or chronic intestinal failure, but is associated with complications. Physicians often lack knowledge in clinical nutrition, which makes clinical decision support tools recommended for prescribing PN. This study evaluated the impact of the OLIVE TREE, a decision tree integrated into the prescribing software at University Hospital Leuven, Belgium, on prescribing behavior and safety.
