Introduction
Studies focusing on catheter removal and the pathogenic spectrum of peritoneal dialysis‐associated peritonitis (PDAP) need to be updated.
Methods
Data were collected from four peritoneal dialysis (PD) centers. Peritonitis rates were compared using Poisson regression and Logistic regression was used to examine the risk factors for catheter removal.
Results
The PD duration (odds ratio [OR], 1.021; 95% confidence interval [CI], 1.010–1.032), number of previous PDAP episodes (OR, 1.267; 95% CI, 1.039–1.545), dialysate white cell count >100 × 106/L on Day 5 of PDAP (OR, 6.088; 95% CI, 3.277–11.312), Pseudomonas aeruginosa (OR, 4.122; 95% CI, 1.071–15.874) and polymicrobial infections (OR, 3.257; 95% CI, 1.519–6.982) were independent predictors of catheter removal (p < 0.05). The prevalence of polymicrobial peritonitis and fungal peritonitis has increased (p < 0.05).
Conclusion
Attention should be paid to patients with long PD duration or a history of previous episodes of PDAP characteristics.
