The UNOS OPTN waiting list and donor registry.
1. On October 31, 1998, there were 62,994 registrants on the combined UNOS waiting list. Of these, 66% were awaiting kidney transplantation, and 18% were awaiting liver transplantation. 2. The majority of patients on the UNOS waiting list on October 31, 1998 were blood type O (52%), White (60%) and male (58%). 3. Median waiting times (MWTs) have increased steadily for nearly every organ since 1988, especially for liver, kidney, and lung registrants. 4. For patients added to the waiting list in 1996. MWTs to transplant were longest for heart-lung registrants (742 days). The shortest waiting times for this cohort were among heart registrants (223 days). No median could be calculated for kidney registrants added in 1996. 5. Death rates per patients waiting at risk declined during 1988-1997. Death rates were higher for patients awaiting life-saving organs (liver, heart, lung, heart-lung) than for non-lifesaving organs (kidney, pancreas, kidney-pancreas). 6. There were 5,478 cadaveric and 3,820 living donors recovered in 1997, a 34% and 109% increase over those recovered in 1988. 7. Large increases were seen in the number of liver (45-84%), pancreas (14-24%), and lung (3-15%) donors between 1988-1997. 8. The number of cadaveric donors aged 50 or older has increased from 12% of all donors in 1988 to 28% of all donors in 1997. 9. The typical cadaveric donor in 1997 was a white male with ABO blood type O, between the ages of 18-34. In 1997, a typical living donor was a white female with ABO blood type O between the ages of 35-49. 10. Between 1988-1997, the percentage of minority donation increased for cadaveric donors (17-24%), and for living donors (23-27%). 11. The number of living donors who were either spouses or unrelated to the recipient increased from 4% in 1988 to 15% in 1997.
