United States

This is perhaps the most important and disturbing abstract dealing
with PD at ASN. It comes from the CANUSA database based on 680
patients in 14 centres in Canada and the USA. It shows that 2-year
survival is 80% in Canada but only 63% in the USA> When a COX
proportional hazards model is used and all risk factors including age,
sex, racek comorbidity, serum albumin and dialysis dose and nutritional
status are corrected for, thee is still an 87% greater risk of death in the
USA compared with Canada. The authors suggest that this disturbing
finding may be related to undetected differences in comorbidity or to
compliance or to "quality assurance policies". This abstract should
stimulate discussion!
