Influence of Experience Acquired by a Liver Transplantation Center on Extension of Donor Acceptance Criteria

Liver transplantation (LTx) is the only effective treatment for end-stage liver failure. Due to the ongoing lack of organs available for transplantation, there is a tendency to extend liver donor selection criteria. The aim of the study was to determine whether extension of donor acceptance criteria with increasing experience in LTx occurred at our transplant center.

This retrospective analysis included 288 donors harvested between 2005 and 2016. The donors were divided chronologically into 4 equally sized groups. They were assessed in subsequent groups according to sex, age, height, body mass index (BMI), cause of death, amount of days spent in the intensive care unit, number of episodes of cardiac arrest before organ removal, and results of laboratory and virologic tests.

A statistically significant increase in the age of accepted donors was observed between group 2 and group 4 (median 40 vs 45 years, P < .05). There was a significant increase in the acceptance of anti-HBc-positive donors (0% in group 1 vs 7% in group 4). The remaining parameters did not show statistically significant differences.

Experience acquired by our transplant center during the period of analysis did not lead to extension of liver donor acceptance criteria. Statistically significant differences for liver donor age and virologic profile (anti-HBc) between groups were observed; however, overall analysis did not confirm a clear tendency to extend liver donor acceptance criteria at this center.
