Catheter Diversion Procedure With Exit-Site Renewal Promotes Peritoneal Dialysis Catheter Survival.

ABSTRACT:

Introduction

Catheter-related infections such as exit site infection (ESI) and tunnel infection (TI) are major causes of peritoneal dialysis (PD) discontinuation. For ESI/TI treatment, catheter diversion procedure (CDP) with exit-site renewal for catheter salvage presents an alternative to catheter removal. Nevertheless, CDP capability of improving PD catheter survival remains unclear.

Methods

We retrospectively reviewed our hospital patients who started PD during 2001-2019 (n=148): 33 treated for ESI/TI by CDP (CDP group) and 115 treated for ESI/TI using conservative therapy or none (non-CDP group). A "virtual discontinuation group" was designated for patients in the CDP group who had received PD catheter removal instead of CDP and who had stopped PD. Kaplan-Meier analysis and log-rank test PD were used for intergroup catheter survival comparison. Associations between clinical factors and PD discontinuation or death were examined using Cox proportional hazards regression analyses.

Results

For patients (76% male, mean age of 61.7±13.0 years), 40 CDP were performed for 33 CDP group patients. Infection-free rates at 30 and 90 days after CDP were, respectively, 90% and 67%. The CDP group PD catheter survival rate was significantly higher than that of virtual discontinuation group (P < .01) and higher than that of the non-CDP group (P = .03). Multivariate analysis revealed independent association of serum albumin concentration (hazard ratio 0.33, 95% confidence interval 0.17-0.67), PD+HD combination therapy (hazard ratio 0.29, 95% confidence interval 0.17-0.49), and CDP (hazard ratio 0.44, 95% confidence interval 0.24-0.80) with PD discontinuation or death.

Conclusion

Results show that CDP may improve PD catheter survival as an effective and less-invasive surgical treatment for ESI/TI to avoid withdrawal of PD.

Project description:IntroductionUrgent-start peritoneal dialysis (PD) in patients with newly diagnosed end-stage renal disease (ESRD) is a well-tolerated alternative to hemodialysis (HD). The primary aim of this study was to identify the demographic and clinical characteristics of ESRD patients, as well as the presurgical, surgical, and postsurgical factors associated with urgent-start PD complications.MethodsA retrospective cross-sectional observational study was performed on 102 patients with ESRD who merited urgent-start PD from January 2015 to June 2019. The primary clinical outcome measures were catheter leakage, dysfunction, and peritonitis, whereas the secondary outcomes were catheter removal, repositioning, and death. Statistical inferences were made with the χ2 or Fisher's exact test and independent samples t tests.ResultsOne hundred two subjects (65 men, 63.7%) 56.2 ± 15.1 years old were included in this study; 64 of the subjects had diabetes and hypertension (62.7%). Catheter leakage occurred in 8 patients (7.8%), catheter dysfunction in 27 patients (26.5%), and peritonitis in 14 patients (13.7%); meanwhile, catheter removal occurred in 6 patients (5.9%), catheter repositioning in 21 patients (20.6%), and death in 3 patients (2.9%). Peritonitis was associated with younger age (i.e., 47.0 ± 16.8 vs. 57.6 ± 14.4 years; P = 0.014; 95% confidence interval [CI]: 2.2-19.1; odds ratio [OR] 0.96; P = 0.018; 95% CI: 0.92-099), higher creatinine levels upon admission (i.e., 20.2 ± 9.8 vs. 14.1 ± 8.3; P = 0.014; 95% CI: -10.9 to -1.2), and heart failure (OR 4.79; P = 0.043; 95% CI: 1.05-21.88). Patients with abdominal hernia were 7.5 times more likely to have their catheter leak (OR 7.5; P = 0.036; 95% CI: 1.14-49.54). Catheter removal was associated with obesity (i.e., body mass index [BMI] of 31.6 ± 4.1 vs. 25.9 ± 4.9; P = 0.007; 95% CI: -9.8 to -1.6; OR 1.26; P = 0.013; 95% CI: 1.05-1.51) and Modification of Diet in Renal Disease glomerular filtration rate (MDRD-GFR) (i.e., 2.5 ± 0.6 vs. 3.7 ± 2.3; P = 0.003; 95% CI: 0.5-1.9).ConclusionPeritonitis was associated with younger age, higher creatinine levels upon admission, and heart failure; meanwhile, catheter removal was linked to obesity and lower glomerular filtration rate. Compared with previous reports, our study included patients in which PD was initiated shortly after catheter insertion, making the intervention a true urgent-start PD. This study contributes to the existing urgent-start PD literature by providing evidence that urgent-start PD with catheter opening within 72 hours has limited complications, making it a relatively safe option.
