BACKGROUND: Efforts have been made to maximize the utility of each organ transplanted. Policy changes to capture unrealized graft years have been implemented utilizing the kidney donor profile index (KDPI). Understanding the impact of KDPI on long-term graft function is critical to an informed organ acceptance decision. METHODS: We reviewed the records of 309 consecutive deceased adult donor kidney recipients who underwent kidney transplantation at our center. We obtained KDPI of the allografts directly from United Network for Organ Sharing (UNOS) and patients were divided into four categories: KDPI ≤ 20, KDPI 21 - 35, KDPI 36 - 85, and KDPI > 85. RESULTS: Of the 309 recipients, 48 (15.5%) received kidneys from donors with KDPI ≤ 20, 57 (18.4%) from donors with KDPI 21 - 35, 161 (52.1%) from donors with KDPI 36 - 85, and 43 (13.9%) from donors with KDPI > 85. Older recipients were more likely to receive high KDPI kidneys (p = 0.025). Kaplan-Meier analysis demonstrated the KDPI > 35 group had worse survival than the KDPI ≤ 20 group, but KDPI 36 - 85 was not different from KDPI > 85. The rate of poor graft function differed at 1 year: 14.6% of KDPI ≤ 20 recipients, 14.3% of KDPI 21 - 35 recipients, 30.6% of KDPI 35 - 85 recipients, and 40.5% of KDPI > 85 recipients had serum creatinine greater than 2.0 mg/dL at 1 year. KDPI > 35 had statistically significantly greater incidence of poor graft function than KDPI ≤ 35 (p < 0.05). CONCLUSIONS: Our study demonstrates that high KDPI grafts behave more like moderate KDPI grafts (KDPI 35 - 85). Creatinine (Cr) greater than 2.0 mg/dL portends poorer long-term graft survival, and this outcome is similar amongst all recipients of KDPI > 35 allografts. .
