Catheter Event Rates in Medical Compared to Surgical Peritoneal Dialysis Catheter Insertion. Kidney Int Rep 2023; 8:2635-2645.

Abstract
Introduction How patient, center, and insertion technique factors interact needs to be understood when designing peritoneal dialysis (PD) catheter insertion pathways. Methods We undertook a prospective cohort study in 44 UK centers enrolling participants planned for first catheter insertion. Sequences of regressions were used to describe the associations linking patient and dialysis unit-level characteristics with catheter insertion technique and their impact on the occurrence of catheter-related events in the first year (catheter-related infection, hospitalization, and removal). Factors associated with catheter events were incorporated into a multistate model comparing the rates of catheter events between medical and surgical insertion alongside treatment modality transitions and mortality. Results Of 784 first catheter insertions, 466 (59%) had a catheter event in the first year and 61.2% of transitions onto hemodialysis (HD) were immediately preceded by a catheter event. Catheter malfunction was less but infection was more common with surgical compared with medical insertions. Participants at centers with fewer late presenters and more new dialysis patients starting PD, had a lower probability of a catheter event. Adjusting for these factors, the hazard ratio for a catheter event following insertion (medical vs. surgical) was 0.70 (95% confidence interval [CI] 0.43 to 1.13), and once established on PD 0.77 (0.62 to 0.96). Conclusion Offering both medical and surgical techniques is associated with lower catheter event rates and keeps people on PD for longer.

Abstract
INTRODUCTION There is limited information on the trends of peritoneal dialysis (PD) technique survival over time. This study aimed to estimate the effect of calendar time on technique survival, transfer to hemodialysis (HD) (and the individual causes of transfer), and patient survival. METHODS This retrospective, multicenter study, based on data from the French Language Peritoneal Dialysis Registry, analyzed 14,673 patients who initiated PD in France between January 1, 2005, and December 31, 2016. Adjusted Cox regressions with robust variance were used to examine the probability of a composite end point of either death or transfer to HD, death, and transfer to HD, accounting for the nonlinear impact of PD start time. RESULTS There were 10,201 (69.5%) cases of PD cessation over the study period: 5,495 (37.4%) deaths and 4,706 (32.1%) transfers to HD. The rate of PD cessation due to death or transfer to HD decreased over time (PR 0.96, 95% CI: 0.95-0.97). Compared to 2009-2010, starting PD between 2005 and 2008 or 2011 and 2016 was strongly associated with a lower rate of transfer to HD (PR 0.88, 95% CI: 0.81-0.96, and PR 0.91, 95% CI: 0.84-0.99, respectively), mostly due to a decline in the rate of infection-related transfers to HD (PR 0.96, 95% CI: 0.94-0.98). CONCLUSIONS Rates of the composite end point of either death or transfer to HD, death, and transfer to HD have decreased in recent decades. The decline in transfers to HD rates, observed since 2011, is mainly the result of a significant decline in infection-related transfers.

Abstract
Abstract
Background
Technique failure, defined as death or transfer to haemodialysis (HD), is a major concern in peritoneal dialysis (PD). Nurse-assisted PD is globally associated with a lower risk of transfer to HD. We aimed to evaluate the association between assisted PD and the risk of the different causes of transfer to HD.
Methods
This was a retrospective study using data from the French Language PD Registry of patients on incident PD from 2006 to 2015. The association between the use of assisted PD and the causes of transfer to HD was evaluated using survival analysis with competing events in unmatched and propensity score-matched cohorts.
Results
The study included 11 093 incident PD patients treated in 123 French PD units. There were 4273 deaths, 3330 transfers to HD and 2210 renal transplantations. The causes of transfer to HD were inadequate dialysis (1283), infection (524), catheter-related problems (334), social issues (250), other causes linked to PD (422), other causes not linked to PD (481) and encapsulating peritoneal sclerosis (6). Nurse-assisted PD patients were older and more comorbid. Assistance by nurse was associated with a higher risk of death [cause-specific hazard ratio (cs-HR) 2.49, 95% confidence interval (CI) 2.26–2.74], but with a lower risk of transfer to HD [subdistributionHR (sd-HR) 0.68, 95% CI 0.62–0.76], especially due to inadequate dialysis (cs-HR 0.83, 95% CI 0.75–0).
Conclusions
The lower risk of transfer to HD associated with nurse assistance should encourage decision makers to launch reimbursement programmes in countries where it is not available.

Abstract
Rationale & Objective Transitions between dialysis modalities can be disruptive to care. Our goals were to evaluate rates of transition from peritoneal dialysis (PD) to in-center hemodialysis (HD), mortality, and transplantation among incident PD patients in the US Renal Data System from 1996 to 2015 and identify factors associated with these outcomes. Study Design Observational registry-based retrospective cohort study. Setting & Participants Medicare patients incident to end-stage renal disease (ESRD) from January 1, 1996, through December 31, 2011 (for adjusted analyses; through December 31, 2014, for unadjusted analyses), and treated with PD 1 or more days within 180 days of ESRD incidence (n = 173,533 for adjusted analyses; n = 219,787 for unadjusted analyses). Exposure & Predictors Exposure: 1 or more days of PD. Predictors: patient- and facility-level characteristics obtained from Centers for Medicare & Medicaid Services Form 2728 and other data sources. Outcomes Patients were followed up for 3 years until transition to in-center HD, death, or transplantation. Analytical Approach Multivariable Cox regression was used to estimate hazards over time and associations with predictors. Results Compared with earlier cohorts, recent incident PD patient cohorts had lower rates of death (48% decline) and transition to in-center HD (13% decline). Among many other findings, we found that: (1) rates of transition to in-center HD and death were lowest in the 2008 to 2011 cohort, (2) longer time receiving PD was associated with higher mortality risk but lower risk for transition to in-center HD, and (3) larger PD programs (≥25 vs ≤6 patients) displayed lower risks for death and transition to in-center HD. Limitations Data collected on Form 2728 are only at the time of ESRD incidence and do not provide information at the time of transition to in-center HD, death, or transplantation. Conclusions Rates of transition from PD to in-center HD and death rates for PD patients decreased over time and were lowest in PD programs with 25 or more patients. Implications of the observed improved technique survival warrant further investigation, focusing on modifiable factors of center-level performance to create opportunities for improved patient outcomes.

PLoS One 2019; 14:e0218677.

Abstract
Introduction Our objective was to assess whether clusters of centers with similar peritoneal dialysis (PD) catheter related practices were associated with differences in the risk of technique failure. Methods Patients on incident PD in French centers contributing to the French Language PD Registry from 2012 to 2016 were included in a retrospective analysis of prospectively collected data. Centers with similar catheter cares practices were gathered in clusters in a hierarchical analysis. Clusters of centers associated with technique failure were evaluated using Cox and Fine and Gray models. A mixed effect Cox model was used to assess the influence of a center effect, as explained by the clusters. Results Data from 2727 catheters placed in 64 centers in France were analyzed. Five clusters of centers were identified. After adjustment for patient-level characteristics, the fourth cluster was associated with a lower risk of technique failure (cause specific-HR 0.70, 95%CI 0.54–0.90. The variance of the center effect decreased by 5% after adjusting for patient characteristics and by 26% after adjusting for patient characteristics and clusters of centers in the mixed effect Cox model. Favorable outcomes were observed in clusters with a greater proportion of community hospitals, where catheters were placed via open surgery, first dressing done 6 to 15 days after catheter placement, and local prophylactic antibiotics was applied on exit-site. Conclusion Several patterns of PD catheter related practices have been identified in France, associated with differences in the risk of technique failure. Combinations of favorable practices are suggested in this study.
