A review from the last seven years (August 2016-July 2023) of questions posted to the International Society for Peritoneal Dialysis (ISPD) website "Questions about PD" by nurses and physicians from around the world revealed that 19 of the questions were associated with optimal approaches for preventing, assessing, and managing issues related to PD catheter non-infectious complications. Our review focused on responses to these questions whereby existing best practice recommendations were considered, if available, relevant literature was cited and differences in international practices discussed. We combined similar questions, revised both the original questions and responses for clarity, as well as updated the references to these questions. PD catheter non-infectious complications can often be prevented or, with early detection, the potential severity of the complication can be minimized. We suggest that the PD nurse is key to educating the patient on PD about PD catheter non-infectious complications, promptly recognize a specific complication and bring that complication to the attention of the Home Dialysis Team. The questions posted to the ISPD website highlight the need for more education and resources for PD nurses worldwide on the important topic of non-infectious complications related to PD catheters, thereby enabling us to prevent such complications as PD catheter malfunction, peri-catheter leakage and infusion or drain pain, as well as recognize and resolve these issues promptly when they do arise, thus allowing patients to extend their time on PD therapy and enhance their quality of life whilst on PD., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

When a patient on peritoneal dialysis (PD) presents with suspected PD-related peritonitis (e.g. cloudy PD fluid and abdominal pain), one of the most important initial aspects of management is for the nephrology nurse/home dialysis nurse to collect PD effluent specimens for white blood cells count, Gram stain, culture and sensitivity for inspection and to send for laboratory testing before antibiotics are started. A review by seven members of the International Society for Peritoneal Dialysis (ISPD) Nursing Committee of all 133 questions posted to the ISPD website 'Questions about PD' over the last 4 years (January 2018-December 2021), revealed 97 posted by nephrology nurses from around the world. Of these 97 questions, 10 were noted to be related to best practices for PD effluent specimen collection. For our review, we focused on these 10 questions along with their responses by the members of the ISPD 'Ask The Experts Team', whereby existing best practice recommendations were considered, if available, relevant literature was cited and differences in international practice discussed. We revised the original responses for clarity and updated the references. We found that these 10 questions were quite varied but could be organised into four categories: how to collect PD effluent safely; how to proceed with PD effluent collection; how to collect PD effluent for assessment; and how to proceed with follow-up PD effluent collection after intraperitoneal antibiotics have been started. In general, we found that there was limited evidence in the PD literature to answer several of these 10 questions posted to the ISPD website 'Questions about PD' by nephrology nurses from around the world on this important clinical topic of best practices for PD effluent specimen collection. Some of these questions were also not addressed in the latest ISPD Peritonitis Guidelines. Moreover, when polling members of our ISPD Nursing Committee we found when answering a few of these questions, nursing practice varied within and among countries. We encourage PD nurses to conduct their own research on this important topic, focusing on areas where research evidence is lacking., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Incremental peritoneal dialysis (PD) is increasingly advocated to reduce treatment burden and costs, with potential to better preserve residual kidney function. Global prevalence of incremental PD use is unknown and use in Australia and New Zealand has not been reported., Methods: Binational registry analysis including incident adult PD patients in Australia and New Zealand (2007-2017), examining incidence of and outcomes associated with incremental PD (first recorded PD exchange volume <42 L/week (incremental) vs. ≥42 L/week (standard))., Results: Incremental PD use significantly increased from 2.7% of all incident PD in 2007 to 11.1% in 2017 (mean increase 0.84%/year). Duration of incremental PD use was 1 year or less in 67% of cases. Male sex, Aboriginal and Torres Strait Islander (ATSI) or Māori ethnicities, age 45-59 years, medical comorbidities or treatment at a centre with low use of automated PD or icodextrin was associated with lower incidence of incremental PD use. Low body mass index and higher estimated glomerular filtration rate was associated with higher incidence. After accounting for patient and centre variables, commencing PD with an incremental prescription was associated with reduced peritonitis risk (adjusted hazard ratio 0.73, 95% confidence interval (CI) 0.61-0.86).When kidney transplantation and death were considered as competing risks, the association between incremental PD and peritonitis was not significant (sub-hazard ratio [SHR] 0.91, 95%CI 0.71-1.17, p = 0.5), however cumulative incidence of 30-day transfer to haemodialysis was lower in those receiving incremental PD (SHR 0.73, 95%CI 0.56-0.94, p = 0.01). There was no association between incremental PD and death., Conclusions: Incremental PD use is increasing in Australia and New Zealand and is not associated with patient harm.

Background: Peritoneal dialysis (PD) technique survival is an important outcome for patients, caregivers and health professionals, however, the definition and measures used for technique survival vary. We aimed to assess the scope and consistency of definitions and measures used for technique survival in studies of patients receiving PD., Method: MEDLINE, EMBASE and CENTRAL databases were searched for randomised controlled studies (RCTs) conducted in patients receiving PD reporting technique survival as an outcome between database inception and December 2019. The definition and measures used were extracted and independently assessed by two reviewers., Results: We included 25 RCTs with a total of 3645 participants (41-371 per trial) and follow up ranging from 6 weeks to 4 years. Terminology used included 'technique survival' (10 studies), 'transfer to haemodialysis (HD)' (8 studies) and 'technique failure' (7 studies) with 17 different definitions. In seven studies, it was unclear whether the definition included transfer to HD, death or transplantation and eight studies reported 'transfer to HD' without further definition regarding duration or other events. Of those remaining, five studies included death in their definition of a technique event, whereas death was censored in the other five. The duration of HD necessary to qualify as an event was reported in only four (16%) studies. Of the 14 studies reporting causes of an event, all used a different list of causes., Conclusion: There is substantial heterogeneity in how PD technique survival is defined and measured, likely contributing to considerable variability in reported rates. Standardised measures for reporting technique survival in PD studies are required to improve comparability.

Background: There is substantial variation in peritonitis rates across peritoneal dialysis (PD) units globally. This may, in part, be related to the wide variability in the content and delivery of training for PD nurse trainers and patients., Aim: The aim of this study was to test the feasibility of implementing the Targeted Education ApproaCH to improve Peritoneal Dialysis Outcomes (TEACH-PD) curriculum in real clinical practice settings., Methods: This study used mixed methods including questionnaires and semi-structured interviews (pretraining and post-training) with nurse trainers and patients to test the acceptability and usability of the PD training modules implemented in two PD units over 6 months. Quantitative data from the questionnaires were analysed descriptively. Interviews were analysed using thematic analysis., Results: Ten PD trainers and 14 incident PD patients were included. Mean training duration to complete the modules were 10.9 h (range 6-17) and 24.9 h (range 15-35), for PD trainers and patients, respectively. None of the PD patients experienced PD-related complications at 30 days follow-up. Three (21%) patients were transferred to haemodialysis due to non-PD-related complications. Ten trainers and 14 PD patients participated in the interviews. Four themes were identified including use of adult learning principles (trainers), comprehension of online modules (trainers), time to complete the modules (trainers) and patient usability of the manuals (patient)., Conclusion: This TEACH-PD study has demonstrated feasibility of implementation in a real clinical setting. The outcomes of this study have informed refinement of the TEACH-PD modules prior to rigorous evaluation of its efficacy and cost-effectiveness in a large-scale study.

Background: Peritoneal dialysis (PD) is a home-based therapy where nurses train patients in its use. There has been no published randomized controlled trial (RCT) evaluating any specific protocol for nurses delivering PD training. A standardized education package based upon the best available evidence and utilizing modern educational practices may lead to improved patient outcomes. The aim is to develop a standardized, evidence-based curriculum for PD trainers and patients aligned with guidelines from the International Society for Peritoneal Dialysis (ISPD), using best practice pedagogy., Methods: A literature search and clinical audit were conducted to identify current practice patterns and best practice. Results were reviewed by a focus group of practitioners comprising PD nurses, nephrologists, consumers, a medical education expert, and an eLearning expert. From this, a training curriculum and modules were developed., Results: A comprehensive PD training curriculum has been developed, which includes modules for training PD nurses (trainers) and patient training manuals. The package comprises 2 introductory modules and 2 clinical case modules. The curriculum is designed for both interactive digital media (trainers) and traditional paper-based teaching with practical demonstrations (patients). Assessment is also addressed., Conclusion: The need for the development of a comprehensive and standardized curriculum for PD nurse trainers and their patients was confirmed. This paper outlines the process of the development of this curriculum. Pilot testing of the modules was launched in late 2017 to examine feasibility, and planning has commenced for a RCT in 2019 to investigate the effect of the modules on clinical outcomes, and their wider application across Australia and New Zealand., (Copyright © 2019 International Society for Peritoneal Dialysis.)

Background: Evidence of effective interventions to prevent peritoneal dialysis (PD) catheter malfunction before first use is presently insufficient to guide clinical care. Regular flushing of the PD catheter (e.g. before PD commencement) has been adopted by some practitioners in the belief that it will prevent catheter obstruction and/or malfunction. The aim of this study was to characterize and evaluate PD catheter flushing practices across Australian and New Zealand PD units., Methods: An on-line survey was distributed to all 62 PD units in Australia (12 August 2016; n = 51) and New Zealand (2 February 2017; n = 11), with questions relating to PD catheter flushing practices, audit, and outcomes., Results: Forty-nine units of variable size (< 16 to > 100 patients) completed the survey (79% response rate). All centers flushed PD catheters at some stage after insertion as routine unit practice. Forty-one units (84%) routinely flushed during periods of PD rest at varying intervals ranging from alternate daily to monthly. The type and volume of solution used to flush varied between units. Units that practised routine flushing of PD catheters were almost twice as likely to audit their catheter-related outcomes (66% vs 38%, p = 0.23) and more likely to have reported blocked catheters in the preceding 12 months (84% vs 0%, p = 0.01) compared with those units that did not routinely flush PD catheters. Thirty units (61%) regularly audited and monitored catheter-related outcomes., Conclusions: This study identified a wide variation in center practices relating to PD catheter flushing. Drawing conclusions about any relationship between flushing practices and clinical outcomes was impeded by the relatively low uptake of regular auditing and monitoring of catheter-related outcomes across surveyed units. Evaluation of the benefits and harms of standardized PD catheter flushing practices on patient outcomes in a randomized trial is needed to guide practice., (Copyright © 2018 International Society for Peritoneal Dialysis.)
