title: Kidney allocation under the UNOS point system: an update.
abstract: 1. The 1,480 patients awaiting cadaveric renal transplants at 14 Southern California transplant centers as of December 3, 1992, were compared with patients transplanted using a point system for one kidney and a hospital-based allocation for the second, or the current system allocating all locally procured kidneys by the point system with regard to several demographic parameters. 2. Of 1,472 waiting patients with sensitization data, 8.5% were broadly sensitized (> 80% PRA). Of the 737 kidneys allocated by the point system, 7% went to broadly sensitized patients, compared with 3% of 438 kidneys allocated by the hospitals (p < 0.001). 3. Of 1,470 waiting patients with information available, 23% were awaiting a repeat transplant. Under the point system, 18% of kidneys were used for repeat transplants compared with 9% of hospital-allocated kidneys (p < 0.001). 4. Of 1,434 waiting patients where the time waiting was available, 26% had waited 1-2 years, 12% 2-3 years, and 6% more than 3 years. Under the point system, patients waiting longer received significantly more kidneys than those recently added to the list: 35% had waited 1-2 years, 21% 2-3 years and 14% more than 3 years (p < 0.001). Kidneys allocated by the hospitals were transplanted to patients in approximately the same proportions as the waiting list: 29% to those waiting 1-2 years, 10% 2-3 years, and 3% more than 3 years. 5. Racial distribution of recipients was not significantly different under either allocation system from that of the waiting list. Whites comprised 39% of waiting patients, the same as the population of Los Angeles County.(ABSTRACT TRUNCATED AT 250 WORDS)
