Abstract

Background: Recipient functional status prior to transplantation has been found to impact post-transplant outcomes in heart, liver and kidney transplants. However, information on how functional status, before and after transplant impacts post-transplant survival outcomes is lacking.

Aim: To investigate the impact of recipient functional status on short and long term intestinal transplant outcomes in United States adults.

Methods: We conducted a retrospective cohort study on 1254 adults who underwent first-time intestinal transplantation from 2005 to 2022. The primary outcome was mortality. Using the Karnofsky Performance Status, functional impairment was categorized as severe, moderate and normal. Analyses were conducted using Kaplan-Meier curves and multivariable Cox regression.

Results: The median age was 41 years, majority (53.4%) were women. Severe impairment was present in 28.3% of recipients. The median survival time was 906.6 days. The median survival time was 1331 and 560 days for patients with normal and severe functional impairment respectively. Recipients with severe impairment had a 56% higher risk of mortality at one year [Hazard ratio (HR) = 1.56; 95%CI: 1.23-1.98; < 0.001] and 58% at five years (HR = 1.58; 95%CI: 1.24-2.00; < 0.001) compared to patients with no functional impairment. Recipients with worse functional status after transplant also had poor survival outcomes.

Conclusion: Pre- and post-transplant recipient functional status is an important prognostic indicator for short- and long-term intestinal transplant outcomes.
