Catheter infections as a factor in the transfer of continuous ambulatory peritoneal dialysis patients to hemodialysis.

The effect of peritoneal catheter infections on the transfer of continuous ambulatory peritoneal dialysis (CAPD) patients to hemodialysis over a 9-year period were examined. Twenty-seven percent (68/247) of all patients were transferred permanently to hemodialysis after a mean of 15 +/- 14 months of CAPD. An additional 29% transferred temporarily one or more times during the study period (mean time of peritoneal dialysis, 35 +/- 23 months). The reasons for permanent transfer to hemodialysis were catheter infections (15/68, 22%), peritonitis (13/68, 19%), catheter infections associated with peritonitis (10/68, 15%), patient preference (9/68, 13%), mechanical problems (4/68, 6%), noncompliance (7/68, 10%), inadequate clearance or ultrafiltration (6/68, 9%), with other reasons for the remainder (4/68, 6%). Temporary transfers to hemodialysis were also mainly due to catheter infections (32%), peritonitis (23%), and simultaneous catheter infections and peritonitis (24%). Catheter infection rates were much higher in the groups that permanently and temporarily were transferred to hemodialysis in comparison with those patients who remained on peritoneal dialysis. We conclude that catheter infections are a leading cause of both temporary and permanent transfer of CAPD patients to hemodialysis.
