Chronic dialysis in children and adolescents. The 1996 annual report of the North American Pediatric Renal Transplant Cooperative Study.
The 1996 annual report of the North American Pediatric Renal Transplant Cooperative Study (NAPRTCS) summarizes data submitted from 130 centers on 2,208 patients in whom 2,787 independent courses of dialysis were performed between 1 January 1992 and 16 January 1996. Approximately two-thirds of the dialysis population were maintained on peritoneal dialysis (PD), with automated PD remaining the preferred modality. There were 964 episodes of peritonitis in 1,018 patient years, yielding an overall peritonitis rate of 1 episode every 13 patient months. More PD patients attended school full time than hemodialysis (HD) patients at baseline (77% vs. 45%), which continued at 6, 12, and 24 months of followup. There were fewer Hispanic patients who were full-time students, whether on HD or PD, compared with white or black patients; 18% of Hispanic patients did not attend school, even though they were medically capable. The majority of dialysis courses terminated due to transplantation (54%), with change in dialysis modality the next most-common reason (28%). Early dialysis termination for any reason was seen more often in HD than PD (40% vs. 23% at 6 months), but by 24 months similar percentages of PD and HD courses had been terminated (75% HD, 72% PD). The most-common PD access was a Tenckhoff catheter with a single cuff, a straight tunnel and lateral exit site. The majority of HD accesses were external percutaneous catheters, with the sublcavian vein the most-common site. Erythropoietin was administered in 93% of HD and PD patients at 24 months.
