Updated March 2, 2023: The lung allocation system based on continuous distribution was originally scheduled to take effect on March 2, 2023. The lung continuous distribution policy is now expected to implement on March 9, 2023. This system notice has been updated to reflect the change in expected implementation date.
Feb. 2, 2023
In advance of the implementation of continuous distribution of lungs expected March 9, 2023, the lung Composite Allocation Score (CAS) calculator is now available on the OPTN website. The calculator can be found in the Data & calculators’ main menu under Allocation Calculators. Programs can use this calculator to better understand the impact of various clinical characteristics on the lung CAS and estimate a candidate’s score.
When continuous contribution of lungs is implemented, the Lung Allocation Score (LAS) will be replaced by the lung Composite Allocation Score (CAS). The Lung Allocation Score (LAS) calculator will remain available on the OPTN website until implementation.
