The 2001 annual report of the North American Pediatric Renal Transplant Cooperative Study (NAPRTCS) registry includes data on 4,546 dialysis patients. Important trends in dialysis care include a significant increase in the use of peritoneal dialysis catheters with two cuffs (51.6% vs. 36.2%, P<0.001), a Swan neck tunnel (34.1% vs. 20.9%, P<0.001), and a downward pointing exit site (34.9% vs. 29.5%, P<0.001) in patients who initiated dialysis between 1997 and 2000 compared with 1992-1996. Most hemodialysis patients continued to have an external percutaneous catheter as their access at the time of initiation of dialysis (1,550/1,971 patients, 78.6%), but the odds of using a jugular rather than a subclavian vein for these catheters increased by 24% each year between 1992 and 2000. There was a significant trend for increasing use of erythropoietin and by 1996, 96% of patients were prescribed this medication at initiation of dialysis. There was also a modest, but significant, increase in hematocrit in the dialysis registry, as the median hematocrit at 6 months of follow-up was 31% in patients who started dialysis between 1997 and 2000 ( P<0.001).
