Outcomes of locally rejected kidneys transplanted at other centers (import KTX) are unknown. SRTR data from 2000 to 2009 of deceased-donor KTXs excluding 0-mismatch, paybacks, and other mandatory shares were compared by location of KTX at local (n = 48 165), regional (n = 4428) or national (n = 4104) centers using multivariable regression models. Compared to nonmandatory share local transplants, import KTX were associated with significantly higher overall risks of patient death (regional aHR 1.15, p < 0.01; national aHR 1.14, p < 0.01), and graft failure (regional aHR 1.17, p < 0.01; national aHR1.21, p < 0.01). In paired analysis, the risk of delayed graft function (DGF) for import KTX was higher compared to locally transplanted mates (regional aOR 1.53, p < 0.01, national aOR 2.14, p < 0.01); however, despite longer ischemia times, overall graft survival was similar. Mean cold ischemia times (CIT) pre- and post-DonorNet (R) were similar for local and regional transplants, but significantly higher for national transplants (28.9 +/- 9.9 vs. 29.9 +/- 9.7 h, respectively, p = 0.01). Import KTX is associated with increased risks of graft failure, patient death and DGF. In the era of DonorNet (R) cold ischemia times of kidneys imported to regional centers are not improved compared to pre-DonorNet (R); and, those of national centers are significantly prolonged.
