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.<h4>Results</h4>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.<h4>Conclusion</h4>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.PloS onee0218677https://www.ebi.ac.uk/biostudies/studies/S-EPMC6586404biostudies-literaturePatterns of peritoneal dialysis catheter practices and technique failure in peritoneal dialysis: A nationwide cohort study.PMC6586404Vernier ILobbedez TVerger CFabre ELanot ABechade CfalsePatterns of peritoneal dialysis catheter practices and technique failure in peritoneal dialysis: A nationwide cohort study.<h4>Introduction</h4>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.<h4>Methods</h4>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.
