Relationships of race and ethnicity to progression of kidney dysfunction and clinical outcomes in patients with chronic kidney failure.
In the United States, the incidence of end-stage renal disease (ESRD) is much higher for blacks, Native Americans, and Asians than for whites. The incidence of kidney disease is also higher for populations of Hispanic ethnicity. ESRD attributed to diabetes (ESRD-DM), hypertension (ESRD-HT), and glomerulonephritis (ESRD-GN), in this order of frequency, are the major categories of ESRD in the United States for all race/ethnic groups. By using the incidence rates of ESRD, during the period from 1997 through 2000, and with whites as reference, the highest rate ratio (RR) was observed for ESRD-HT in blacks (RR = 5.96), ESRD-DM in Native Americans (RR = 5.11), and ESRD-GN in Asians (RR=2.20). The data suggest that the excess of ESRD observed for racial/ethnic minorities may be reduced by interventions aimed at prevention/control of hypertension and diabetes. The data suggest that before developing ESRD, patients with chronic renal failure from minority groups have to face more barriers to receive high-quality health care. This may explain why they see nephrologists later and are less likely to receive renal transplantation at initiation of renal replacement therapy (RRT). Improvements in quality of care after initiating RRT may explain the lower mortality and higher scores in heath-related quality of life observed for patients from racial/ethnic minorities.
