Background: Improvement of kidney survival after transplantation has mainly been studied in the American population. There, it was found that improvement mostly occurred on the short-term after transplantation. Since the European transplantation reality and survival times considerably differ from the American situation, we investigated changes in survival over the past three decades in Western Europe, accounting for the important changes in donor and recipient characteristics over time.
Methods: We performed a cohort study based on four large prospectively collected clinical databases in Western Europe, in transplants performed between January 1st 1986 and December 31st 2015. Analyses were restricted to adults and to deceased donors, leading to an inclusion of 10.688 single kidney transplantations. The primary outcome was the cause-specific (death-censored) hazard rate of kidney failure after transplantation. In the Cox model, we included a flexible time-dependent effect for the continuous covariate 'transplant year' in order to quantify improvement on both the short- and long-term. All estimates were adjusted for the changing demographics.
Results: There was significant improvement (p<0.001) in graft survival from 1986 to 2000, but no progression (p=0.525) was made after 2000 (figure 1). Also, improvement was more pronounced on the short-term than on the long-term after transplantation (p=0.003). These changes were conditionally independent of the changing donor and recipient age (both increased significantly with p<0.001).Conclusion: In Western Europe, similar to what was noted earlier in the US, improvement of kidney graft survival over the past decades occurred primarily on the short-term after transplantation, and to a lesser extent on the long- term. For the first time, however, we demonstrate that no improvement in graft survival was observed since 2000, even when taking into account the increased risk profiles of donors and recipients. Novel initiatives to further improve graft survival after kidney transplantation are urgently needed.
