Background: Although several studies have demonstrated the economic advantages of peritoneal dialysis (PD) over hemodialysis (HD), few reports in the literature have compared the costs of HD and PD access. The aim of the present study was to compare the resources required to establish and maintain the dialysis access in patients who initiated HD with a tunneled cuffed catheter (TCC) or an arteriovenous fistula (AVF) and in patients who initiated PD.

Methods: We retrospectively analyzed the 152 chronic kidney disease patients who consecutively initiated dialysis treatment at our institution in 2008 (HD-AVF, n = 65; HD-CVC, n = 45; PD, n = 42). Detailed clinical and demographic information and data on access type were collected for all patients. A comprehensive measure of total dialysis

access costs, including surgery, radiology, hospitalization for access complications, physician costs, and transportation costs was obtained at year 1 using an intention-to-treat

approach. All resources used were valued using 2010 prices, and costs are reported in 2010 euros.

Results: Compared with the HD-AVF and HD-TCC modalities, PD was associated with a significantly lower risk of access-related interventions (adjusted rate ratios: 1.572 and 1.433 respectively; 95% confidence intervals: 1.253 to 1.891 and 1.069 to 1.797). The mean dialysis access-related costs per patient–year at risk were €1171.6 [median: €608.8; interquartile range (IQR): €563.1 – €936.7] for PD, €1555.2 (median: €783.9; IQR: €371.4 – €1571.7) for HD-AVF, and €4208.2 (median: €1252.4; IQR: €947.9 - €2983.5) for HD-TCC (p < 0.001). In multivariate analysis, total dialysis access costs were significantly higher for the HD-TCC modality than for either PD or HD-AVF (β = –0.53; 95% CI: –1.03 to -0.02; and β = -0.50; 95% CI: -0.96 to -0.04).

Conclusions: Compared with patients initiating HD, those initiating PD required fewer resources to establish and maintain a dialysis access during the first year of treatment.
