Background

Patients who start intermittent peritoneal dialysis (IPD) as a bridge therapy to continuous ambulatory peritoneal dialysis (CAPD) may present failure of the IPD technique before starting due to multiple factors. The principal factors identified with loss of technical were peritonitis, tunnelitis, and definitive failure. The aim of this study was to estimate the incidence of technique failure in IPD patients with the IPD program at the General Hospital of Mexico.

Methods

Retrospective cohort study that included 199 patients with IPD, was reviewed the patient records of peritoneal dialysis, during the period between January 2008 and May 2023. The incidence was estimated, as and risk factors for technique failure.

Results

A total of 199 patient records were included; 58% (115) were men, with a mean age of 45.4±14.9 SD years, 65% (127) had diabetes type 2, and 94% had systemic hypertension. In the 62% (123) patients, the initiation of renal function replacement therapy was urgent. It was identified that in 70% (139) of patients, the first catheter was placed percutaneously and 30% (60) was surgical. The catheter type was pig tail in the 93% (185) of the cases. the loss of technique was identified in 24% (48) of patients, including as causes of etiologies events of dysfunction that required catheter replacement and events of peritonitis, the analysis of the first event of peritonitis increased the risk of loss technique (OR 10.1, 95%IC 4.8- 21, p=0.0001). In the follow-up period, 35% (70) of the patients were present with at least one event of peritonitis, 40% (80) presented dysfunction; and 30% turned to hemodialysis.

Conclusion

The principal factor associated with losing the technique was peritonitis, even when the patient did not use dialysis outside of the hospital. Peritonitis is a frequent and serious complication of peritoneal dialysis (PD), representing the most common cause of conversion to hemodialysis in the long term. It is necessary to integrate strategies for the care and management of the ambulatory catheter during IPD.
