Kidneys from donors over 60 were linked to more graft loss and recipient deaths

Design

Systematic review and meta-analysis of seven observational studies

Population

19,210 kidney transplant recipients

Primary outcome

Death-censored graft survival and patient survival by donor age

Effect

Graft loss HR 1.73 (95% CI 1.34–2.24); mortality HR 1.42 (1.05–1.94); rejection OR 0.86 (0.60–1.23)

A meta-analysis of seven observational studies including 19,210 kidney transplant recipients examined outcomes by donor age.

Older donor age was associated with higher death-censored graft loss (HR 1.73, 95% CI 1.34–2.24) and higher recipient mortality (HR 1.42, 1.05–1.94), most clearly for donors over 60. Acute rejection rates did not differ (OR 0.86). Heterogeneity was moderate to high, and the evidence base is small.

Older donors expand the organ pool, and for many recipients an older kidney now is better than a younger kidney years later on dialysis. The practical point is matching: older kidneys to older recipients, with expectations set accordingly. In India, where living donors are often parents of the recipient, donor age is a frequent counselling question.

• Counsel recipients that kidneys from donors over 60 carry higher graft-loss risk
• Consider age-matching older donor kidneys to older recipients
• Do not refuse an older donor kidney on age alone — weigh it against time on dialysis
• Older donor age was not linked to more acute rejection

Why it matters

Donor age is a frequent and emotionally loaded question in living-donor programmes.

Don't overread it

This pools seven observational studies with substantial heterogeneity; it cannot separate donor age from other donor and recipient factors.

The statistics, in plain English

A hazard ratio of 1.73 for graft loss means grafts from older donors failed at about 1.7 times the rate, after excluding deaths with a working graft.
