Potential Bias and Misconceptions in Liver Transplantation for Alcohol- and Obesity-Related Liver Disease

INTRODUCTION: Bias and misconceptions surrounding alcohol-related liver disease (ALD) and obesity-related liver disease (OLD) may lead to transplant listing inequities. The aim of this study was to evaluate patients, medical students, residents, fellows, and attending physicians for bias and misconceptions regarding liver transplantation (LT) for patients with ALD and OLD. METHODS: Participants took a survey asking them whether patients with ALD who continue/discontinue drinking alcohol or patients with OLD who do/do not commit to a weight loss program deserve equal LT rights. A Likert scale was used for their responses. Participants also estimated 5-year survival and advanced fibrosis recurrence after LT. The primary outcome of the study was bias measured by expected agreement or disagreement to questions using a Likert scale, significant underestimation of a 5-year survival rate after LT, and significant overestimation of 5-year advanced fibrosis recurrence after LT. RESULTS: A total of 381 participants were included in the analysis: 153 residents/fellows, 31 attending physicians, 98 medical students, and 99 patients. A higher percentage from all 4 participating groups either were neutral or disagreed with equal LT rights for patients with ALD who discontinue drinking compared with patients with OLD who commit to weight loss program. The attending physician group was the only group with a majority estimating >60% 5-year survival after LT in patients with ALD and OLD (P < 0.05). All 4 groups had a majority estimate >20% 5-year advanced fibrosis recurrence in patients with ALD and OLD (P > 0.05). DISCUSSION: There seems to be current bias and misconceptions regarding LT for patients with ALD and OLD.
