US Kidney Transplant Centers Exhibit 16-Fold Variation in Patient Wait Times Due to Differing Organ Acceptance Criteria

The US transplant system relies on a national matching algorithm fed by organ procurement organizations, yet each center maintains independent listing criteria and risk tolerance. A large observational analysis of kidney programs documented a 16-fold difference in time to transplantation between the fastest and slowest centers, driven partly by willingness to use kidneys from older or anatomically complex donors. Patients such as Katherine Screws who listed at multiple sites succeeded where single-center attempts failed, underscoring that geography and center policy, not solely medical urgency, determine outcomes.

Public SRTR dashboards now display center-specific metrics on transplant rates, wait-list mortality, and graft survival, including personalized decision guides that adjust for age and comorbidities. These tools synthesize data previously used mainly by researchers, allowing direct comparison of roughly 250 kidney programs. Early adoption remains limited, however, because referring physicians still default to the nearest facility.

Broader analysis of SRTR and CMS data shows that centers with higher volumes more frequently accept marginal organs without compromising one-year graft survival, yet regulatory oversight has not standardized acceptance thresholds. This variation persists despite a decade-long rise in deceased-donor transplants to over 49,000 in the most recent year.

Future studies should track whether increased patient use of SRTR tools shifts listing patterns and reduces geographic disparities; such analyses require linkage of listing data to actual transplant events over at least three years.
