LifeCenter Northwest President & CEO, Kevin O’Connor, co-authors study in upcoming Journal of the American Society of Nephrology (JASN)
A new study just released indicates that many donated organs that are discarded might be suitable for transplantation if certain steps are taken to limit damage following donation. The findings appear in the Journal of the American Society of Nephrology. LifeCenter Northwest’s President & CEO and study co-author, Kevin O’Connor states, “In summary, there is an opportunity to substantially and safely increase the benefit of kidney transplantation in the U.S.”
The study offers insights on how to decrease the discard rate of donated organs specifically by transplanting more kidneys from donors after circulatory death and limiting the amount of time between recovery and transplantation, or “cold ischemia” time.
In the United States, most transplanted organs come from donors declared dead by neurologic criteria (brain death). Donation after circulatory death (DCD)—in which circulation, heartbeat, and breathing have permanently stopped—has become increasingly more common, however, accounting for 17.7 percent of deceased donors in 2015 compared with only 7.3 percent in 2005. However, in some parts of the U.S., like the service area of LifeCenter Northwest, this “DCD rate” exceeds 30 percent.
To examine the contemporary use and outcomes of DCD kidneys for transplantation in the United States, John Gill, MD, MS (University of British Columbia and Vancouver’s Providence Health Care) and his colleagues examined national data obtained between 2008 and 2015. The number of DCD kidneys recovered by the country’s 58 donor service areas varied substantially (from 0 to 1072), and 25 percent of DCD kidneys were recovered in only 4 donor service areas. Overall, 20 percent of recovered DCD kidneys were discarded, varying from 3 percent to 33 percent among donor service areas.
DCD kidneys exhibited excellent organ survival, with a 5-year survival rate of 75 percent. DCD kidneys were at higher risk of failing when compared with kidneys from brain dead donors, only when the cold ischemia time was >12 hours.
“We found that use of DCD kidneys is variable throughout the United States, that the outcomes are generally excellent, and that the use of these organs could probably be safely increased if cold ischemia times are limited,” said Dr. Gill.
