Access to dialysis in New Zealand renal services

To assess the equity of access to dialysis treatment in New Zealand renal services.

All patients with chronic renal failure assessed by NZ renal services for whom a decision regarding dialysis was made in the years 1997 and 1998 were entered into the study. Information collected included patient demographics, cause of renal failure, scores for comorbidity and activities of daily living (ADL), renal centre and dialysis decision.

Records were available for 823 patients, of whom 710 were offered dialysis and 676 accepted treatment. Compared with those who accepted an offer of dialysis, those not offered treatment were older (67.4 vs 53.3 years, p <0.001), and had higher scores for comorbidity (340 vs 128, p <0.001) and ADL (150 vs 32, p <0.001), but there was no difference in primary disease incidence. Patients at one centre were referred with significantly higher average comorbidity, and at two centres with significantly different ADL scores, than those referred to the reference centre. The acceptance rate was significantly lower at one centre when adjusted for age, ethnicity, gender, and comorbidity and ADL scores.

Of all referred patients, 13.7% were not offered dialysis treatment. They had significantly higher comorbidity, and were older and more disabled than those patients offered treatment. There was one centre with a significantly lower adjusted acceptance rate.
