What is Driving Racial Disparities in Access to Living Donor Liver Transplants

Posted on by

Recent articles highlight a huge gap in the availability of living donor liver transplants (LDLTs) when examined based on racial/ethnic background.

  • YR Nobel et al. Liver Transpl 2015; 21: 904-13.
  • A Doyle et al. Liver Transpl 2015; 21: 897-903.

What is the reason for this inequality?

The first study examined UNOS data from 2002-2014 among adult liver transplant recipients.  Of 35,401 recipients, 2171 (6.1%) received a LDLT.

Key findings:

  • Cholestatic liver disease: When compared with white patients, the odds ratios of receiving LDLT were 0.35 for African American, 0.58 for Hispanic, and 0.11 for Asian.
  • Noncholestatic liver disease: When compared with white patients, the odds ratios of receiving LDLT were 0.53 for African American, 0.78 for Hispanic, and 0.45 for Asian.
  • LDLT recipients were more likely to have private insurance

The second study did not look at racial/ethnic background but instead focused on other recipient factors.  Using a retrospective cohort of 491 consecutive patients, they determined that all of the following resulted in a lower likelihood of LDLT:

  • Single — OR 0.34
  • Divorced –OR 0.53
  • Immigrant — OR 0.38
  • Low income quintile — OR 0.44

Together these studies allow speculation on why there is such a disparity.

  • Financial costs, including lost wages, could preclude those with lower socioeconomic status from being available as donors
  • Distrust of donation system and/or fear of surgery

Bottomline: Racial/ethnic differences and financial resources are associated with significant access inequality to living donor liver transplantation.
