Factors that impact on the quality of life of intestinal failure patients treated with home parenteral nutrition: protocol for a multicentre, longitudinal observational study

Abstract

BackgroundHome parenteral nutrition (HPN) refers to the intravenous administration of macronutrients, micronutrients and fluid. The aims of treatment are to increase survival and improve quality of life (QoL). However, patients struggle with physiological symptoms, time-consuming invasive therapy and an increased occurrence of depression and social isolation. Our aim is to understand how HPN impacts the QoL of patients, and the contribution played by the complications of treatment, for example, liver disease.Methods and analysisA multicentre, longitudinal, observational study will be conducted using routinely collected clinical data. Participants will also be asked to complete three QoL questionnaires (EuroQol-5 Dimensions, Short Form 36 and HPN-QoL) at baseline and 12 months. The primary outcome is mean change in QoL scores over 12 months. Secondary outcomes include how factors including liver function, gut microbiota, number of infusions of PN per week, nutritional composition of PN and nutritional status impact on QoL scores.Ethics and disseminationEthical approval was obtained from HRA and Health and Care Research Wales Research Ethics Committee (21/SC/0316). The study was eligible for portfolio adoption, Central Portfolio Management System ID 50506. Results will be disseminated through peer-reviewed scientific journals and presented at national and international meetings.
