The impact of intestinal transplantation on quality of life

Intestinal failure (IF) and intestinal transplant (ITx) are associated with poor quality of life (QoL). Disease-specific assessment of QoL for IF and ITx is challenging, owing to the different problems encountered. We have sought to compare QoL pre-ITx with post-ITx and have compared generic QoL with a stable IF population.

Two prospectively maintained databases of patients referred for and undergoing ITx and a chronic (Type 2 & 3) IF cohort were interrogated. QoL instruments used were generic (EQ-5D-5L and SF-36) and disease-specific (HPN-QOL and ITx-QOL). Analysis used Student's t-test and one-way ANOVA with Bonferroni correction for multiple comparisons. Data were collected pre- and post-ITx at 3, 6, 12-months and yearly thereafter.

All QoL instruments improved following ITx to levels comparable with a cohort of stable IF patients not requiring ITx. Both the visual analogue score component (EQ-5D-5L) and the effect of underlying illness on QoL (HPN-QOL/ITx-QOL) were higher following ITx than either pre-ITx or when compared with the IF cohort. Effects on general health, ability to eat and drink, to holiday and travel were improved as early as 3 months post-ITx. Other components did not before 6-12 months following ITx, but were maintained to at least 24 months. Patient personal financial pressures are greater following ITx, even in a publicly funded healthcare system.

ITx has beneficial effects on QoL compared to those assessed for or awaiting ITx. QoL following ITx is similar to patients with IF not requiring ITx. A QoL instrument that covers the journey of patients from IF through ITx would assist longitudinal analysis of the value and timing of ITx at an individual level.
