This paper reviews the rationale behind the proposed policy of using perito
neal dialysis (PD) as the initial treatment modality in patients with end-s
tage renal disease (ESRD). The better preservation of residual renal functi
on associated with PD is emphasized along with its potential cardiovascular
benefits. The superior patient survival on PD, relative to hemodialysis, d
uring the first 2 years on dialysis in both the United States and Canada is
discussed, as are the potential advantages of PD in terms of hepatitis C p
revention, anaemia management and quality of life. The lower cost of PD in
association with these clinical advantages lead to the modality being more
cost-effective in the early years on dialysis. The relatively high techniqu
e failure rate on PD, however, subsequently leads to an increasing need for
haemodialysis. A policy of integrated dialysis care with PD first and then
haemodialysis, as required, is advocated as a more cost-effective approach
to ESRD in suitable patients.
