Abstract

Due to criticism regarding undue adherence to fixed geographic boundaries, the Lung Allocation Score system was recently replaced by the more holistic allocation via continuous distribution. This review highlights the historical evolution of US lung allocation paradigms, outlines rationale for continuous distribution under the Composite Allocation Score system and discusses expected implications of this new system.

Keywords: lung transplantation; organ allocation; transplantation.
