RESUMEN
Product shortages related to the components of parenteral nutrition (PN) therapy have been well described over the past decade. The situation has more recently worsened and expanded globally because of the impact the COVID-19 pandemic has placed on supply chain issues and workforce demand. The impact of enteral nutrition (EN) product shortages is less well documented when compared with PN, and development of management strategies is often left up to the discretion of individual providers. The recent crisis in infant formula supply has heightened the national awareness of how a nutrition support product shortage can significantly impact patient safety. This review provides a historical perspective of PN and EN product shortages to gain insight into the lessons learned and applies this to strategies for managing current and future product shortages. Strategies for managing PN and EN shortages can best succeed if they are tailored to address aspects that are unique to the inpatient and outpatient care setting. In addition, patients who transition between care settings are vulnerable to harm related to product shortages if measures are not in place to communicate and address these shortages. Teamwork and communication within an organization and among key stakeholders are necessary to develop processes that aim to minimize patient harm related to product shortages.
