Equity in liver transplantation: are we any closer?

PURPOSE OF REVIEW

As policies governing liver transplantation (LT) continue to change and influence clinical practice, it is important to monitor trends in equitable access and outcomes amongst patients. The purpose of this review is to closely examine recent advances and findings in health equity research in LT over the last 2 years; specifically evaluating inequities at the different stages of LT (referral, evaluation, listing, waitlist outcomes and post-LT outcomes).

RECENT FINDINGS

Advancements in geospatial analysis have enabled investigators to identify and begin to study the role of community level factors (such as neighborhood poverty, increased community capital/urbanicity score) in driving LT disparities. There has also been a shift in investigating center specific characteristics that contributes to disparities in waitlist access. Modification to the current model for end stage liver disease (MELD) score policy accounting for height differences is also crucial to eradicating the disparity in LT amongst sexes. Lastly, Black pediatric patients have been shown to have higher rates of death and worse posttransplant outcome after transitioning to adult healthcare.

SUMMARY

Although, there have been some advances in methodology and policies, inequities in waitlist access, waitlist outcomes and posttransplant outcomes continue to be pervasive in the field of LT. Future directions include expansion of social determinants of health measures, inclusion of multicenter designs, MELD score modification and investigation into drivers of worse posttransplant outcomes in Black patients.
