Management of long‐term home parenteral nutrition: Historical perspective, common complications, and patient education and training

Intestinal failure (IF) is a rare disease that requires ongoing intravenous supplementation to sustain growth and health. Advancements in parenteral nutrition (PN) and central venous access in the 1960s and 1970s transformed a life-limiting disease to a chronic one in which patients are able to administer hydration, electrolytes, micronutrients, and macronutrients in the comfort of their home. However, despite ongoing advancements in the field of home PN (HPN), complications-whether related to central venous catheters or PN itself-remain common and can be associated with significant morbidity and mortality. Central venous access can be associated with thrombosis, central line-associated bloodstream infection, or damage and can result in loss of access over time. PN can be associated with IF-associated liver disease or hyperglycemia. The key to preserving central venous access and quality of life and maintaining health for patients with chronic IF (CIF) is education focused on prevention and prompt management of CIF complications as they arise. This education typically takes place at the time of initiation of HPN, either in the hospital setting or in the patient's home. The present manuscript describes the historical progression of HPN, prevalence and characteristics of CIF, and an in-depth discussion of the most common catheter-related and PN-related complications and their management, along with a discussion of our education and training process.
