Racial/ethnic disparities in access and outcomes of simultaneous liver-kidney transplant among liver transplant candidates with renal dysfunction in the United States.
Since the Model for End-stage Liver Disease (MELD) allocation system was implemented, the proportion of simultaneous liver-kidney transplantation (SLKT) has increased significantly. The investigators study whether racial/ethnic disparities exist in access to SLKT and post-SLKT survival. The investigators concluded that in the MELD era, racial/ethnic differences exist in access and survival of SLKT for patients with renal dysfunction at listing for LT.

A concentric neighborhood solution to disparity in liver access that contains current UNOS districts.
Policymakers are deliberating policy reforms to reduce geographic disparity in liver allocation. This study conducted simulations comparing current allocation with the neighborhoods and sharing policies. The study concluded that the current 11 districts can be adapted systematically by adding neighboring donor service areas (DSAs) to improve geographic disparity, mortality, and airplane travel distance. Modifications to Share 35 and Share 15 policies result in further improvements.

Predicting liver transplant capacity using discrete event simulation.
The researchers constructed a discrete event simulation model informed by current donor characteristics to predict future liver transplant trends through the year 2030. They found that by altering assumptions about the future donor pool, their model can be used to develop policy interventions to prevent a further decline in this lifesaving therapy.
