Evaluation of living liver donors.

As a result of the cadaveric organ shortage, the number of centers performing living donor liver transplantation has increased. Living donor liver transplantation provides immediate organ availability and avoids the risk of life-threatening complications that occur with long waiting times for cadaveric organs; however, it puts a healthy person at risk for little personal gain. A standardized approach to donor evaluation ensures safety to potential donors. Careful medical (physical examination as well as laboratory and radiological evaluation) and psychological evaluation is imperative to reduce donor complications and ensure good outcomes in recipients. A social worker and psychiatrist assess for mental competency, provide emotional support, and can serve as independent donor advocates. Informed understanding and consent are crucial aspects of the evaluation and include ensuring that the donor understands all potential complications and is free of coercion. Safety of the donor must be the highest priority.
