title: Dialysis survival in a large inner-city facility: a comparison to national rates.
abstract: Impoverished patients may represent a high-risk population with poor survival. With 1993 U.S. Renal Data System survival tables (to adjust the risk of death for differences in age, race, and ESRD diagnosis), the mortality rates of patients over 3 yr in a large inner-city dialysis facility using high-flux technique were compared with national averages. At least 93.7% of patients were African-American, 50% had incomes below $7,000 per year, and employment was 5% or less. Observed and expected deaths (the latter derived from the U.S. Renal Data System tables) were used to calculate a standardized mortality ratio (observed deaths/expected deaths); the U.S. average is 1.0. The standardized mortality ratio at this facility for each year was < 0.600 and was significantly lower than the U.S. average in 1991, in 1992 (P < 0.05), and for all 3 yr (P < .001). Over all 3 yr, it was lower for females (0.540, P < 0.05), males (0.620, P < 0.05), patients with diabetes (0.593, P < 0.05), and glomerulonephritis (0.318, P < 0.05). For the 3 yr, a Cox regression analysis revealed independent associations between mortality and age (P = 0.004), serum albumin (P = 0.02), Kt/V (P = 0.02), and dialysis for more than 2 yr (P = 0.01). Patients with economic hardship can attain survival significantly better than the national average with the provision of adequate dialysis, nutrition, and support services.
