Impact of new variables reported to the UNOS registry

1. Donor age is now a predominant factor influencing graft outcome. 2. A new finding here is that recipient peripheral vascular disease, PVD is also a major factor. This factor was independent of whether the patient had diabetes or not. Presensitization, as shown by a high PRA is additive to PVD. 3. Hypertension in the donor was important only when a history of more than 10 years was noted in the older donors over age 50. 4. Angina and cardiovascular disease in the patient resulted in a slightly higher death rate, but was only of importance in patients over age 50. 5. Cadaver donor pretreatment was of importance only in donors over age 30. 6. White patients with private insurance had a slightly higher graft survival rate than those on Medicare or Medicaid. Black patients with private insurance had almost the same graft survival as White patients with private insurance. The lowest graft survival was noted for Black patients on Medicaid.
