What is the most recent number of transplants separated by type of transplant?
In total, 17,611 kidney transplants were done in 2015; this includes adult, pediatric, and combined organ transplantation. Of those, 12,280 transplants were from a deceased donor and 5331 transplants were from a living donor.
What are the recent trends affecting the wait list?
For the first time in 10 years, the overall wait list decreased from 99,120 at the beginning of 2015 to 97,680 at the end of the year. This is due to:
- 1. Less inactive patients on the list
- 2. Increased transplant rate with the new allocation system
- 3. Removal of those medically ineligible
- 4. A decrease in number of new listings
There is no advantage in the new system for listing inactive patients. The number of active patients increased from 47,000 patients in 2005 to 61,000 patients in 2015. In 2015, 31,672 patients were removed from the kidney wait list. Out of those removed from the wait list, 17,611 patients underwent kidney transplantation and about 5000 patients died. In the last 5 years, there has been almost a 3-fold increase in the number of patients removed from the wait list for medical reasons, from 1533 patients in 2010 to 4154 patients in 2015.
Has the age of patients on the waiting list changed over the last few years?
Yes. Patients older than 65 years of age grew from 14.5% of the list in 2005 to 22% in 2015. If this pace continues, patients over 65 years of age will outnumber patients 25 to 49 years of age in about 2020. Patients over 65 now are less willing to accept a kidney with a KDPI score >85%. However, the number of patients being transplanted in this age group has decreased from previous years. This was a concern of the new allocation system; it is also likely secondary to a decreased willingness to accept a kidney with a higher KDPI score.
What is the most common cause of kidney disease in patients on the wait list?
Diabetes and hypertension are the most common causes of chronic kidney disease in the general population, so it is not surprising that the both are the main causes of kidney disease of those on the wait list. Glomerular disease as the cause of kidney disease in patients on the wait list has declined over the last decade.
What is the definition of an inactive patient on the wait list?
An inactive patient is defined as a transplant candidate who is considered temporarily unsuitable for kidney transplantation. These patients usually have a medical condition that temporarily makes them unable to receive a kidney transplant. Patients still accrue waiting time. Once the condition is resolved, the patient is reinstated to the active wait list and is eligible for kidney transplant allocation.
The most common reason for being inactive at time of listing is incomplete medical workup. The changes to the allocation system in 2014 allow for dialysis patients to complete their workup and still receive credit for their time on dialysis (see Question 2, Time on Wait List). This does not help the predialysis patient, so their workup should be completed as quickly as possible.
Does a candidate’s blood type affect their time on the waiting list?
- • AB: wait time 2 years
- • A: wait time 3 years
- • O: wait time 5 years
- • B: wait time 6 years
What is the median time to transplantation for individuals on the waitlist?
As of 2015, the median wait time for a kidney transplant was 3.6 years.
