Trends in Organ Donor Management: 2002 to 2012

BACKGROUND: Refinements in donor management have resulted in increased numbers and quality of grafts after neurologic death. We hypothesize that the increased use of hormone replacement therapy (HRT) has been accompanied by improved outcomes over time. STUDY DESIGN: Using the Organ Procurement and Transplant Network donor database, all brain-dead donors procured from July 1, 2001 to June 30, 2012 were studied. Hormone replacement therapy was identified by an infusion of thyroid hormone. An expanded criteria donor was defined as age 60 years or older. Incidence of HRT administration and number of donors and organs recovered were calculated. Using the Organ Procurement and Transplant Network thoracic recipient database transplant list, wait times were examined. RESULTS: There were 74,180 brain-dead donors studied. Hormone replacement therapy use increased substantially from 25.6% to 72.3% of donors. However, mean number of organs procured per donor remained static (3.51 to 3.50; p = 0.083), and the rate of high-yield donors decreased (46.4% to 43.1%; p < 0.001). Incidence of traumatic brain injury donors decreased (42.1% to 33.9%; p < 0.001) relative to an increased number of expanded criteria donors (22.1% to 26%). Despite this, there has been an increase in the raw number of donors (20,558 to 24,308; p < 0.001) and organs (5,857 to 6,945; p < 0.001). There has been an increase in organs per traumatic brain injury donor (4.02 to 4.12; p = 0.002) and a decrease in days on the waiting list (462.2 to 170.4 days; p < 0.001) for a thoracic transplant recipient. CONCLUSIONS: The marked increase in the use of HRT in the management of brain-dead donors has been accompanied by increased organ availability overall. Potential mechanisms might include successful conversion of previously unacceptable donors and improved recovery in certain subsets of donors. (C) 2014 by the American College of Surgeons
