Center Geography or Center Practice? Decomposing Geographic Variation in Access to Kidney Transplantation Before Versus After Circles

Key Points

• Investigate the causes of geographic variation in access to kidney transplantation before and after policy changes.
• Analyzed differences in kidney transplantation rates across various centers.
• Examined offer acceptance rates of kidney transplants by different centers.
• Compared disparities before and after the implementation of KAS250.
• Identified that center-level practice differences are the main drivers of geographic disparities in transplantation rates.
• Noted that KAS250 reduced disparities at the DSA (donor service area) level.
• Concluded that further policy changes are unlikely to significantly impact geographic variation in DDKT (deceased donor kidney transplantation) rates.
