Decline in available liver transplants expected
Date:1/10/2013

A new study, funded in part by the National Institutes of Health (NIH) and Health Resources and Services Administration, and published in the January 2013 issue of Liver Transplantation, a journal of the American Association for the Study of Liver Diseases (AASLD), found that the non-use of donor livers climbed through 2010 due to a worsening of donor liver quality, primarily from donation following cardiac death. Diabetes, donor age, and body mass index (BMI) were also linked to a decrease in use of organs.

"For patients with end-stage liver disease, transplantation is the only option for extending life, but organ availability places constraints on the transplant community," explains Dr. Eric Orman with the University of North Carolina School of Medicine in Chapel Hill. "One of the methods to increase the donor pool is to include donors with less than ideal health statusthose with fatty livers, older donors, and donation after cardiac death."

In an attempt to increase available livers for transplant, the transplant community has gradually extended donation criteria. However, previous research shows that poor outcomes may occur following transplant of more inferior organs. In fact, studies have shown an increased recipient morbidity and mortality risk with donation after cardiac death (when circulation ceases) than with standard donation following brain death in which donor circulation is sustained.

For the present study researchers used data from the Organ Procurement and Transplantation Network (OPTN) to indentify 107,259 deceased donors in U.S. between 1988 and 2010. Donors were 18 years of age and older who had a least one organ (liver, heart, intestine, kidney, lung or pancreas) used for transplantation. The mean donor age was 44 years; 41% were female and 68% were white. Split liver donations and donors with BMI less than 14 kg/m2 or more than 50 kg/m2 were excluded.

Analysis indicates that 41,503 donations o
