Reorganizing organ procurement organization (OPO) regions can increase liver transplants. This study developed a framework to optimize transplant allocation efficiency and geographic parity, potentially saving more lives.

Area of Science:

  • Organ transplantation logistics
  • Health services research
  • Operations research in healthcare

Background:

  • The United States currently has 11 organ procurement organization (OPO) regions of varying sizes.
  • Current OPO region configurations impact organ travel time and post-transplant viability.
  • Optimizing these regions is crucial for efficient organ allocation.

Purpose of the Study:

  • To establish a methodologic framework for optimizing OPO region configurations.
  • To maximize transplant allocation efficiency and geographic parity across regions.
  • To improve organ viability by minimizing travel time.

Main Methods:

  • Developed an integer programming model to optimize region configuration.
  • The model maximized intraregional transplants and geographic parity.

  • Sensitivity analyses explored different liver travel time-viability functions.

    • Main Results:

    • Reconfiguring OPO regions could increase liver transplants by up to 17-18 per year.
    • The number of additional transplants depends on the travel-viability function used.
    • Optimized regions enhance both transplant numbers and fairness.

    Conclusions:

    • Reorganization of OPO regions shows potential to significantly benefit liver transplantation.
    • The developed analytic framework is adaptable for optimizing other organ transplant systems.
    • This research offers a data-driven approach to improve national organ allocation.
