Parenteral nutrition (PN) is a complex therapy with numerous opportunities for error during the prescribing, preparation, and administration processes. Advances in technology, such as computerized provider order entry (CPOE), electronic health records (EHRs), and clinical decision support (CDS) have helped decrease the risks associated with PN therapy. These technologies can be utilized to guide prescribing, provide automated safety checks, and increase overall safety and accuracy in PN ordering, compounding, and administration. In recent years, increased awareness of the risks associated with PN therapy, in particular issues with ordering and transcription, have magnified the need for improved support of PN ordering within currently available systems. Additionally, drug shortages continue to impact key components of PN admixtures, further increasing the risks associated with this complex therapy. These concerns and risks present an opportunity for the development of new functionality, as well as improvements in and innovative utilization of available technology within systems supporting the PN use process. This discussion will highlight the risks associated with PN, examine the role of drug shortages on the safety of this therapy, describe the application of available technology to manage shortages, and report the experience of using commercially available CDS tools at one academic medical center. It will also include a discussion of the transition from paper orders to CPOE/EHR-based orders for PN and the transition from one commercially available electronic system to another at this particular institution. © 2020 American Society for Parenteral and Enteral Nutrition.
