Abstract

BACKGROUND AND OBJECTIVES:

Expanded-criteria donor (ECD) kidneys are used to expand the number of deceased-donor kidney transplants, often for elderly recipients. This study sought to determine whether older recipients had significantly worse outcomes from receiving ECD kidneys and whether outcomes of ECD versus standard-criteria donor (SCD) kidneys differed in younger recipients.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS:

This is a single-center, retrospective review of all primary deceased-donor kidney transplantations performed between 2000 and 2005. Group 1 consisted of patients ≥60 years of age (n=189) who received an ECD (n=96) or an SCD (n=93) kidney. Group 2 consisted of patients 40-59 years of age (n=370) who received an ECD (n=105) or an SCD (n=265) kidney.

RESULTS:

Older recipients (group 1) who received ECD kidneys demonstrated significantly shortened 5-year actuarial patient and graft survival rates compared with older recipients of SCD allografts. Group 1 ECD recipients also had significantly worse outcomes than younger (group 2) ECD recipients. In multivariate analysis, ECD kidneys remained an independent predictor of poorer outcome in group 1.

CONCLUSIONS:

Morbidity and mortality were increased in elderly recipients of ECD kidneys. These findings may have implications in kidney allocation policy developments that encourage placement of ECD kidneys for older recipients.
