Geographic location continues to influence access to donor lungs across the United States, despite recent reforms to the national allocation system designed to reduce regional inequities, according to a comprehensive analysis by Cleveland Clinic and Case Western Reserve University researchers.
Geographic Variations in Lung Transplant Access
Cleveland Clinic and Case Western Reserve University study findings
Policy Changes Show Limited Impact on Regional Equity
The study examined outcomes following updates to the national lung allocation system, which were implemented to address geographic inequities in organ distribution. According to researchers from Cleveland Clinic and Case Western Reserve University, the analysis revealed that regional differences in access to donor lungs have not been eliminated as intended.
The research team analyzed transplant data across multiple regions to assess whether policy changes achieved their goal of creating more equitable access. Their findings indicate that geographic location remains a significant predictor of transplant opportunities, suggesting that current allocation mechanisms may require further refinement.
Allocation System Updates Fall Short of Equity Goals
The national lung allocation system underwent revisions aimed at reducing regional disparities and improving overall organ utilization efficiency. However, the Cleveland Clinic and Case Western Reserve University analysis demonstrates that these changes have not fully addressed the underlying geographic inequities that have long characterized lung transplantation in the United States.
The study contributes to ongoing discussions about organ allocation policy and highlights the need for continued monitoring of geographic equity in transplant access. For more analysis of health policy impacts on patient outcomes, see our policy coverage.
Implications for Transplant Candidates and Programs
The persistent geographic disparities identified by the Cleveland Clinic and Case Western Reserve University study have important implications for patients awaiting lung transplantation and the centers that serve them. According to the United Network for Organ Sharing, understanding these patterns is crucial for both clinical decision-making and future policy development.
The findings also underscore the importance of continued research into factors that drive geographic disparities in organ allocation. Our new studies section regularly covers emerging research on transplant medicine and organ allocation policy.
Geographic location remains an important factor in access to donor lungs in the United States, even after recent updates to the national lung allocation system.

Key takeaways
- Regional disparities in lung transplant access persist despite recent policy reforms, according to Cleveland Clinic and Case Western Reserve University study
- Geographic location continues to influence patient outcomes and wait times
- Further refinements to allocation systems may be needed to achieve equity goals
Frequently asked questions
What did the Cleveland Clinic study find about geographic disparities?
The study found that despite policy changes, geographic location remains an important factor in access to donor lungs in the United States, even after recent updates to the national lung allocation system changed how donor lungs are distributed.
Who conducted this research?
The analysis was conducted by researchers from Cleveland Clinic and Case Western Reserve University, as reported by Medical Xpress in 2026.
The study highlights the ongoing challenges in achieving equitable organ allocation across diverse geographic regions and healthcare systems. As transplant medicine continues to evolve, addressing these disparities remains a critical priority for ensuring fair access to life-saving treatments for all patients regardless of their location.
