[Home parenteral nutrition: a consensus document of experts from Andalucia and Extremadura].

Home parenteral nutrition (HPN) is a technique that has allowed the survival in the community of those patients with serious diseases resulting in an intestinal failure that made their nutrition impossible by other methods. It is indicated if there is a documented intestinal failure (understood by the reduction of the intestinal function to the minimum to the point that intravenous supplementation is required to maintain health and/or growth) with impossibility for oral or enteral exclusive nutrition, provided that there is the possibility of managing the patient at home and that there is no short-term survival expectancy. It requires taking into account the patient's quality of life, family environment and the capacity of the patient and/or their caregivers to be trained for HPN therapy. In low prevalence health topics, as intestinal failure, where the available scientific evidence is of poor quality, consensus documents add value in decision-making. Furthermore, HPN is a complex process and, although there is extensive experience in its application and even clinical practice guidelines, in daily practice there are uncertainties about its suitability, usefulness, rational use and associated costs. For this reason, this document of consensus has been carried out, using the GRADE method. With this document we intend to define our position with regard to the current use of HPN in our country and answer several controversial questions related to this treatment.
