BACKGROUND: The most common definition of delayed graft function (DGF) relies on dialysis during the first week post-transplant and does not consider DGF severity. The impact of DGF severity on long-term graft outcome remains controversial.
METHODS: We analysed 627 deceased-donor kidney transplant recipients (KTRs) transplanted in 2005-2015 at our centre for DGF severity, associated risk factors and long-term consequences of DGF.
RESULTS: We found 349 (55.7%) KTRs with DGF, which were classified into four groups according to DGF duration (0-1, 2-7, 8-14, >14 days) and were compared with KTR with no DGF. A longer duration of DGF was associated with progressive worsening of 10-year death-censored graft survival {no DGF: 88.3% [95% confidence interval (CI) 82.4-94.2]; 0-1 day: 81.3% [95% CI 68.2-94.4], 2-7 days: 61.5% [95% CI 43.1.1-79.9], 8-14 days: 66.6% [95% CI 47.4-85.8], >14 days: 51.2% [95% CI 33-69.4]; P < 0.001}. In kidneys with a Kidney Donor Profile Index (KDPI) ≥85%, all DGF severity groups demonstrated reduced graft survival. However, in the <85% KDPI kidneys, only >14 days DGF duration showed worse outcomes.
CONCLUSIONS: DGF had a duration-dependent effect on graft survival, which varied depending on the KDPI. Of note, 0- to 1-day DGF showed comparable results to no DGF in the whole cohort.
