Background:Living donation is the potential solution to increasing donor donor shortage. This retrospective analysis of UNOS database analyses the outcome of living donor transplantation across 4 eras and report the results in adults .
Methods: Retrospective analysis all living donation performed in United States 1987 -2015. The period was divided into era 1987-1994, 1995-2001, 2002-2008 and 2009-2015. The outcome in adults transplant recipients were analyzed. Test of equality over strata by Log Rank and Wilcoxon Statistics for data analysis. P value of <0.05 was considered significant.
Results: A total of 114,620 adult patients were analysed. There was significant improvement in graft survival in adults with each successive era. Five year adult survival:76.6, 79.7, 83.1 and 85.4 with each successive era. 10 years outcomes:graft survival rates 56.1, 58.6 and 62.6% with each successive era. Trend persist in year 15 with 37.7% first era vs 39.98% second era. Rank statistics and test of equality over strata showed p value <0.0001. Living donor rates were 23, 35, 40 and 35% for each successive era. Median age 36, 43, 48, 50 with each successive era, donor age 37, 39, 41, 43 years respectively. Biological relatedness: 93.6, 76.9, 62.5 and 50.1%. T50% Living vs DD 11.6 vs 7, 12.2 vs 8.4, >14.3 vs 9.3 years in each successive era.
See [Table1] and [Figure1]

Conclusion:
Significant improvement graft survival adult living donor transplants in successive era despite increased recipient, donor age and less relatedness. Further studies will elucidate the factors leading to improved outcomes.
