Peritonitis rates in CAPD patients using the UVXD and O-set systems.
We report experience with O-set and UVXD systems. Sixty-nine O-set patients (34 male; mean age +/- SD = 45.7 +/- 13.2 years) were compared with 54 UVXD patients (27 male; 56.8 +/- 16.8 years). Total (mean +/- SD) experience were 974 (14.1 +/- 10.8) months on O-set and 1010.9 (18.7 +/- 15.7) months on UVXD. Thirty-two O-set patients avoided peritonitis; 37 had 91 episodes. Seventeen UVXD patients avoided peritonitis; 37 had 137 episodes. Peritonitis occurred each 10.7 months (O-set) versus 7.4 months (UVXD), which was significantly different (p = 0.032, Z test; 95% confidence interval = -0.142 to +0.226). There were 18 relapses in 9 O-set patients, 34 in 12 UVXD. Gram-positive organisms caused 58.2% and 66%; gram-negative, 13.2% and 8.8%; and culture negative, 24.2% and 23.4% of peritonitis in O-set and UVXD, respectively. The time to first peritonitis was not different, 7.4 +/- 6.6 months O-set and 7.2 +/- 7.9 months (UVXD). There was no difference in the peritonitis-free period, 13.0 +/- 10.0 months (O-set) and 16.5 +/- 14.3 months (UVXD). There were 1.12 (O-set) and 16.1 (UVXD) cases per patient year, and 10.7 (O-set) and 7.43 (UVXD) patient months per episode. The peritonitis rate odds ratio was 1:1.85 (O-set:UVXD).
