KDPI is a predictor of deceased-donor (DD) graft survival, calculated using donor factors. It does not consider recipient or other post-procurement factors. This retrospective analysis reviews historical outcomes of high KDPI organs (>80%) at our center.
490 adult DD kidney-alone transplants performed at our center between 2005 and 2012 were retrospectively analyzed. Follow up median time was 5.3 years (Range 0-10.5).
142 KDPI <35% grafts were transplanted, 279 with KDPI 35-79% and 69 with KDPI>80%. 1, 3 and 5 year graft survival rates (with 95% confidence intervals) for high KDPI kidneys were 94% (85-97), 89% (81-94) and 73% (60-84) exceeding UNOS published data (85%, 71% and 57% respectively for KDPI of 85).The difference in survival for the KDPI 35-79% and >80% groups was statistically non-significant, p=0.58.
KDPI>80% group had more older male recipients.
| High KDPI (80-100%) (n=69) | Medium KDPI (35-79%) (n=279) | p Value | |
| Age (years, mean±SD) | 57±10.9 | 51±12.1 | 0.0006 |
| Male | 72.5% | 59.1% | 0.04 |
| African-American | 46.4% | 37.6% | 0.18 |
| Diabetes (recipient) | 37.7% | 34.8% | 0.65 |
| Cold Ischemia Time (hour, mean±SD) | 15±5.6 | 16±5.9 | 0.24 |
| Import | 8.7% | 16.8% | 0.09 |
| Pumped | 44.9% | 33.3% | 0.07 |
| Delayed graft function | 17.4% | 16.8% | 0.91 |
| Acute rejection during first year | 20.3% | 14% | 0.19 |

Univariate analysis showed significantly worse outcomes for African-American (AA) recipients in KDPI 35-79% and >80% groups (p=0.011 and 0.002 respectively) with no significant difference in the <35% group (p=0.71). Diabetes was associated with worse outcomes in all groups (p<0.001). Cox multivariate analysis for graft loss in KDPI>80 showed AA Hazard ratio 4.3 and pump HR 0.3.
| HR | p Value | 95% CI | |
| African-American Recipient | 4.3 | 0.006 | 1.5-12.5 |
| Pump | 0.3 | 0.03 | 0.1-0.9 |

Our results suggest high KDPI grafts can have similar outcomes to medium KDPI with use of pump preservation and minimizing use in high risk recipients(diabetics, AA, highly sensitized and retransplants).
