Is Age a Limitation for Organ Donation? A Comparison of Elderly and Non-elderly Donors in a Deceased Donor Organ Transplantation Program from South India.

Abstract

To bridge the gap between demand and supply of organs, deceased donors with extreme ages can be utilized. The object of this study was to compare elderly with non-elderly donors and to assess the predictors of organ utilization or wastage. This was a retrospective chart analysis. Univariate and multivariate logistic regression analysis of cohorts was carried out to predict organ utilization or wastage. Of the 716 deceased donors, 16.2% were elderly (≥60 years) and 83.8% were not elderly (≤59 years). Donors in the elderly cohort were more likely to be diabetic, hypertensive, overweight, and smokers compared with non-elderly donors. They had deranged terminal creatinine and succumbed to cerebrovascular accident or intracerebral hemorrhage. They had a high kidney donor risk index (KDRI) of 1.83 ± 0.46. Those in the younger donor cohort, were more likely to have succumbed to road traffic accident-associated traumatic brain injury, were subjected to more efforts to revive them in the intensive care unit via cardiopulmonary resuscitation, had deranged liver function tests, and had a KDRI of 0.93 ± 0.28. The kidney discard rate (KDR) and liver discard rate (LDR) in the elderly donors was 50% and 8.6%, respectively (vis-a-vis the non-elderly at 13.3 % and 7.5%). The KDR was significantly higher than the LDR in elderly donors. The main reason for this was the high number of "marginal kidneys". We revealed that elderly donors formed a significant proportion of deceased donors. The utilization of the liver from deceased donors was more frequent compared with the kidney.
