Risk of peritoneal dialysis (PD)-related peritonitis - competing risks analysis
| Variable | Hazard ratio (competing risks multivariable) | P value |
|---|---|---|
| Primary kidney disease | ||
| Diabetic nephropathy | ||
| Hypertension | 0.9 (95% CI: 0.6–1.2) | 0.4 |
| Polycystic kidney disease | 1.1 (95% CI: 0.6–2.1) | 0.9 |
| Glomerulonephritis | 0.9 (95% CI: 0.6–1.3) | 0.6 |
| Other | 0.6 (95% CI: 0.4–1.1) | 0.1 |
| Early-start peritoneal dialysis (ESPD) vs. conventional-start peritoneal dialysis (CSPD) | 1.0 (95% CI: 0.7–1.4) | 0.99 |
| Modified Seldinger vs. laparoscopic PD catheter insertion technique | 1.3 (95% CI: 0.9–1.9) | 0.1 |
| Infectious complications | ||
| PD exit site infection | 0.8 (95% CI: 0.6–1.0) | 0.1 |
| Tunnel infection | 0.5 (95% CI: 0.2–1.2) | 0.1 |
| Mechanical complications | ||
| Pericatheter leak | 0.8 (95% CI: 0.4–1.5) | 0.4 |
| Malposition | 0.6 (95% CI: 0.3–1.1) | 0.1 |
CI, confidence interval.
A multivariate competing risk analysis was performed to examine variables contributing to time to PD-related peritonitis. The timing of PD commencement or catheter insertion technique did not significantly influence this outcome.
