New rules for allocating scarce kidneys will result in 6.4 percent more blacks getting transplants, while slightly increasing the number of unsuccessful transplants, a study finds.
Blacks and other minorities have long been disadvantaged on transplant waiting lists -- in part because the scoring system gave strong priority to compatibility between a recipient and the donated organ. Although blacks donate organs as often as whites, they have an extremely wide variety of protein markers on the outside of their cells -- making an exact match much harder to find than for whites.
The new rules, implemented in May by the United Network for Organ Sharing, stop giving priority for a certain type of immunological match known as HLA-B. Researchers used a statistical method to predict what would happen under the new rules.
- Had the new rule been in effect in the year 2000, 2,292 blacks would have gotten kidneys, up 6.4 percent from the actual number of 2,154 blacks.
- Meanwhile, 3,954 whites would have gotten the organs, a decrease of 4 percent.
- Hispanics would have seen a 4.2 percent increase and Asians would have seen a 5.9 percent increase.
- In addition, in the first four months of the new rules, 39 percent of available kidneys went to blacks, Hispanics, Asians and other minorities -- an increase of 7 percent over the same period in 2002.
The study indicates that the new rules will lead to about 2 percent more organs being rejected in all races. However, researchers say that is a fair tradeoff. Improved organ transplant methods, including better transplant-rejection drugs, have made strict matching far less necessary than it was in 1988 when the original rules were implemented.
