Improving liver transplant organ allocation policies based on age and location differences.

Official title: Estimating the Causal Effect of Liver Allocation Policy Reflecting the Heterogeneity from Age and Geography

Funded at University of Iowa · NIH-10887536 · Data updated 2026-11-12

This study looks at how liver transplant organs are given out, especially considering the ages and locations of patients, to help create a fairer system that ensures everyone has a better chance of getting the transplant they need.

Who could benefit from this research

Could help

Ideal candidates for this research are patients with chronic liver diseases who are on the waiting list for liver transplants.

Less likely to help

Patients who are not on the liver transplant waiting list or do not have chronic liver diseases may not benefit from this research.

What this research studies

This research investigates how liver transplant organs are allocated, focusing on the differences in age and geographic location of patients. It aims to develop a fairer and more efficient organ allocation policy by analyzing observational data to estimate the causal effects of current policies. The study will utilize advanced statistical methods to emulate randomized trials, which are typically not feasible in this context. The goal is to address disparities in organ allocation that can lead to unequal access for patients in need of transplants.

Why it matters

Potential benefit: If successful, this research could lead to more equitable liver transplant policies, improving access to transplants for patients across different demographics.

How similar studies have gone: While there have been incremental changes in organ allocation policies, this research aims to provide a novel approach to understanding and improving these policies through causal inference methods.
