Background
Causes of non-resuming peritoneal dialysis (PD) after complicated peritonitis requiring peritoneal catheter (PC) removal remain poorly studied.
Methods
We reviewed all peritonitis episodes in our center between 1997 and 2017. Patients who restarted PD after PC removal (Group 1) were compared to those who did not (Group 2), identifying the causes.
Results
Of 284 peritonitis episodes, PC was removed in 48 patients (16.9%). In 18 (37.5%) patients PC was reinserted, and PD successfully resumed in all, with a median duration of PD afterwards of 14.1 months. In other 30 (62.5%) reinsertion of PC was not attempted. Causes of non-reinsertion were: transfer to hemodialysis 76.6% (n = 23), death 16.7% (n = 5) and transplantation 6.7% (n = 2). Hemodialysis switch was due to non-medical reasons in 47.8% (n = 11) including fear of peritonitis, family decision and social dependence. Group 1 was younger (p = 0.041), with lower Charlson index (p = 0.045) and higher men proportion (p = 0.049). Group 1 had a better patient survival than group 2 (survival at 24 months: 67% and 53%, respectively; log-rank test p: 0.01). There were no differences in survival between groups when adjusted for significant basal characteristics.
Conclusions
Resuming PD after severe peritonitis requiring PC removal is feasible but a high proportion of patients do not restart PD for non-medical reasons, usually older patients with higher Charlson index. A properly structured interview would be a useful tool that could improve return to technique in these patients.
