A new way of allocating donor lungs that eliminates geographical restrictions could save more lives, new research suggests. In early 2023, the current U.S. system, which looks for compatible candidates within a fixed radius, will be replaced by the Composite Allocation Score. The new score will prioritize a candidate’s medical needs. “The importance of removing the geographical barrier can’t be overstated here,” said study author Dr. Maryam Valapour, senior investigator for lung transplantation at the U.S. Scientific Registry of Transplant Recipients (SRTR). “The Composite Allocation Score system’s goal of making access to lung transplant more equitable for all candidates in the United States will help reduce waitlist [death rates] and we hope will even improve post-transplant survival over time.” The current system gauges donor and recipient compatibility, geographical restrictions and prioritizes calculated survival after transplant, according to a study led by Valapour and colleagues at the SRTR and the Cleveland Clinic, where she is director of lung transplant outcomes. That system first looks at compatibility within a 250-mile radius. But someone who needs the lungs more quickly may live just outside that boundary. The new system is meant to improve equity in organ allocation by prioritizing a patient’s medical needs and eliminating geographical boundaries. To investigate the potential impact of the change, Valapour’s team tested six alternate scenarios in 10 simulations. They used data from… read on > read on >
