Quality of care among Aboriginal hemodialysis patients.

Abstract

Registry data report racial differences in hemodialysis (HD) care, with ethnic minorities at a disadvantage. However, little information is available regarding Aboriginal HD patients specifically. This study sought to compare the quality of HD care between Aboriginal and non-Aboriginal patients in Canada. All adults who were established on HD for > or = 6 mo in a single Canadian province were included. Clinical information was obtained by patient interview and chart review, with race determined by self-report. Quality of HD care was assessed by small solute clearance, BP control, mineral metabolism, and anemia management. Of the 835 patients, 95 (11.4%) were Aboriginal. Aboriginal patients were significantly younger, were more likely to have diabetes as the cause of ESRD, and had a higher degree of comorbidity than non-Aboriginal patients. There were no differences between Aboriginal and non-Aboriginal patients for small solute clearance, anemia management, or use of permanent vascular access. Aboriginal patients, however, were less likely to achieve a target predialysis systolic BP of < 140 mmHg (29.5 versus 44.9%; P = 0.004), a target phosphate level of < 1.8 mmol/L (40.0 versus 67.3%; P < 0.0001), and a calcium-phosphate product < 4.4 mmol2/L2 (52.6 versus 72.7%; P < 0.001). Quality of care was found to be similar for Aboriginal compared with non-Aboriginal HD patients except for differences in predialysis systolic BP and mineral metabolism, which may be influenced by individual and cultural factors. Explanations for these differences and their impact on morbidity and mortality warrant further investigation.
