Risk of transfer to hemodialysis-competing risks analysis
| Variable | Hazard ratio (competing risks multivariable) | P value |
|---|---|---|
| Primary kidney disease | ||
| Diabetic nephropathy | ||
| Hypertension | 0.3 (95% CI: 0.1–1.3) | 0.1 |
| Polycystic kidney disease | 0.7 (95% CI: 0.2–2.5 | 0.6 |
| Glomerulonephritis | 1.2 (95% CI: 0.6–2.4) | 0.6 |
| Other | 1.0 (95% CI: 0.4–2.2) | 0.97 |
| Early-start peritoneal dialysis (ESPD) vs. conventional-start peritoneal dialysis (CSPD) | 0.8 (95% CI: 0.4–1.5) | 0.5 |
| Modified Seldinger vs. laparoscopic peritoneal dialysis (PD) catheter insertion technique | 1.0 (95% CI: 0.5–1.9) | 0.98 |
| Infectious complications | ||
| PD-related peritonitisa | 2.7 (95% CI: 1.5–4.8) | 0.001 |
| PD exit site infection | 0.9 (95% CI: 0.5–1.6) | 0.7 |
| Tunnel infection | 1.9 (95% CI: 0.7–5.2) | 0.2 |
| Mechanical Complications | ||
| Pericatheter leak | 1.4 (95% CI: 0.4–4.5) | 0.6 |
| Malposition | 2.8 (95% CI: 1.3–6.0) | 0.01 |
| Pleuroperitoneal leak | 12.7 (95% C.I 5.7–28.4) | <0.001 |
A multivariate competing risk analysis was performed to examine variables contributing to time transfer to hemodialysis. Although timing of PD commencement and catheter insertion technique did not influence this outcome, the presence of PD-related peritonitis, catheter malposition, or pleuroperitoneal leak significantly shortened the time to transfer to hemodialysis.
