Improvements in Outcomes for Ethnic Minorities During the Share 35 Era Are Not Due to Decreased Rates of Early Graft Loss.

Objectives: Our aim was to investigate the effects of the Share 35 policy on outcomes in ethnic minorities and recipients who experienced early graft failure.

Materials And Methods: We analyzed donor and recipient data from the United Network for Organ Sharing database before (June 6, 2011 to June 18, 2013) and after (June 18, 2013 to June 30, 2015) implementation of Share 35. Graft and patient survival outcomes were compared.

Results: There were significant differences in 1- and 2-year graft and patient survival rates between ethnicities pre-Share 35 (P = .03, P < .001, P = .01, P < .001, respectively). There were no significant differences in 1- and 2-year graft and patient survival between ethnicities post-Share 35 (P = .268, P = .09, P = .343, P = .087, respectively). There were no differences in early graft failure rates pre- and post-Share 35 at 7 days (2.1% vs 2.0; P = .71) and 30 days (4.0% vs 3.8%; P = .47) after transplant, with a decreased early graft failure rate shown at 90 days after transplant (6.8% vs 5.8%; P = .003). When analyzed separately, the low Model for End-Stage Liver Disease (score of < 35) and the high Model for End-Stage Liver Disease recipients (score of ≥ 35) both exhibited reduced early graft failure rates post-Share 35 (6.1% vs 5.3% and 10.8% vs 7.8%, respectively; P < .05).

Concluions: Share 35 was associated with a short-term reduction in ethnic disparities. Most ethnic groups experienced improved survival in the Share 35 era. Share 35 was not associated with an increase in early graft failure and is an efficacious policy with regard to short-term outcomes.
