Isolated pancreas transplantation: Is rank list position related to outcomes of imported grafts?

Transplant centers may decline an import pancreas offer based on demographics and laboratory test results, without information on actual gland quality. The relationship between position on the match run, indicative of the number of centers that chose not to use a pancreas, and patient and death-censored graft survival, is not known. We studied all 199 isolated pancreas grafts transplanted at the University of Wisconsin since July 2000 and compared overall patient and death-censored graft survival based on import vs local status. Of the 199 isolated pancreas transplants, 184 (92.5%) were imported from another donor service area with a median match rank of 49 (interquartile range 14-129). Median cold ischemia time was longer for imported pancreata (16.6 vs 13.4 hours, P = .02). In multivariate Cox modeling, there was no association with position on the rank list and patient (P = .44) or death-censored graft survival (P = .99). There was an overall rate of 6.5% of graft failure within 30 days; however, there was no association with position on the rank list and graft failure at 30 days (P = .33). Although the logistics may be challenging, sound judgment to accept offers independent of prior centers' decisions can result in quality utilization of imported pancreata.
