[Evolution of patients with home parenteral nutrition: a systematic review of available studies].

Introduction

home parenteral nutrition (HPN) is a fundamental treatment for patients with intestinal failure who do not require hospitalization. We aimed to conduct an epidemiological and clinical practice analysis of HPN through a systematic review.

Methods

the systematic review was conducted according to the PRISMA guidelines. A search was performed using the Healthcare Databases Advanced Search of PubMed® and EMBASE®, to identify articles which followed patients treated with HPN for at least 5 years, published between 2009 and 2019 in English or Spanish language. In addition, we manually retrieved other publications of interest. We excluded articles about subgroups of patients with a specific pathology, cancer or pregnant patients. We excluded studies collecting exclusively HPN complications.

Results

a total of 267 references were identified, of which 9 met criteria (3 of pediatric population and 6 of adults). In adults, the main difference found between publications was the underlying pathologies. The most common indication was short bowel syndrome and the main cause of exitus was the underlying pathology. Most of the pediatric patients received this support in the first months of life. In addition, children showed a higher conversion rate to oral intake and a lower number of deaths when compared to adults.

Conclusions

the use of HPN in cancer pathology is subject to wide geographic variability. It would be advisable to establish indication guidelines in patients with cancer and conduct quality studies, which provide rigorous and homogeneous information.
