Older kidney transplant recipients are at higher risk of hospitalization and AKI, mainly due to infections and surgical complications. Hospitalization and AKI significantly impact graft survival, highlighting the importance of addressing comorbidities and risks in the pre-transplant and outpatient setting.
Background: Older kidney transplant recipients (OKTR) are vulnerable to infections and AKI, often prompting hospitalization. This study elucidates etiology of hospitalizations, AKI, and outcomes in OKTR. Methods: Retrospective study of 500 patients age >= 60, who underwent kidney transplantation from 2005-2015. Demographic, transplant, and outcomes data were collected. Results: OKTR had mean age 66 years; 59% males and 50% African Americans. 62% had at least one hospitalization post transplant. Predictors of hospitalization were DGF, DM, panel reactive antibodies (PRA), dialysis duration. Hospitalization was mostly due to infection and surgical complications. Average length of stay was 6.4 days. OKTR with at least one hospitalization had 84% higher risk for graft loss (p=0.001). 56% of older kidney transplant recipients had at least one AKI episode post transplant. Predictors of AKI included DGF, older, African American donor, and tacrolimus variability. The most common etiologies for AKI were infection, dehydration, and GI complications. OKTR with at least one AKI episode had 2.6-fold higher risk for graft loss (p<0.001). Conclusions: Post-transplant hospitalization and AKI in OKTR significantly impact graft survival. Addressing comorbidities and risks in the pre-transplant and outpatient setting may help alleviate burden of hospitalization and risk of AKI in OKTR and improve graft outcomes.
