Using a multidisciplinary training program to reduce peritonitis in peritoneal dialysis patients

Ten things I wish I knew as a new peritoneal dialysis nurse

A nurse new to home peritoneal dialysis (PD) undoubtedly has to learn all the steps for continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) procedures, along with basics such as hand hygiene, ordering supplies, disposing of supplies, recognizing signs and symptoms of peritonitis. However, it is not always clear what else the new PD nurse needs to know in order to successfully teach a patient all that a patient (and care partner) starting home PD training need to know, as well as to support that patient overtime once the patient is performing PD at home. To answer this question, using a modified Delphi technique, members of the International Society for Peritoneal Dialysis (ISPD) Nursing and Allied Health Professional Committee identified the top 10 practice advice (tips) these nurse members thought all new home PD nurses should know and be aware of. For each tip, we justified the importance of the tip and how it could be implemented. The 10 tips were quite varied and highlighted both the breadth and the depth of knowledge a new PD nurse needs to acquire over and above basic knowledge and skills such as performing CAPD and APD and recognizing signs and symptoms of peritonitis. The members of the ISPD Nursing and Allied Health Professional Committee who compiled this list of the top 10 tips, believe that through understanding the importance, justification, and implementation of each of these tips, the nurse new to a home PD program can, in turn, appreciate more how to individualize home PD training sessions, improve the quality of life for patients on PD, as well as extend the patients' time on PD.

Peritoneal dialysis training and interventions: A narrative review

BackgroundPeritoneal dialysis (PD) training and education for patients and their caregivers, provided by PD nurses, are crucial for effective PD programs. The goal is to impart sufficient knowledge, skills, training, and support to minimize complications. However, the evidence regarding effective educational interventions during training has been unclear and inconsistent. The review question was: How do PD training methods and educational interventions impact on PD outcomes in adult patients?MethodsA narrative review was undertaken with defined inclusion and exclusion criteria of articles published in the last 10 years. Databases were searched, followed by a selection process conducted with the project team. Quality appraisal and a final selection were uploaded to Excel, and data was extracted. A narrative description of the results was then completed.ResultsA total of 982 articles followed the selection process of these 21 studies, including mixed methods research design, but all met the inclusion criteria. The results were described under headings of training methods, educational interventions, patient characteristics, retraining, and outcomes reported.ConclusionsThe narrative review highlights gaps in robust evidence for educational interventions during training. However, some evidence supports adapting PD training methods to incorporate more individualized approaches, appropriate pre-training assessments, and consistent outcome measures.

Structured training initiative (STI) for caregivers of children on peritoneal dialysis: a prospective study of the impact on the rate of peritonitis

BACKGROUND

Training caregivers performing PD is an important measure to prevent peritonitis. A low literacy rate hinders training in low-resource settings. We designed a structured training initiative (STI) and objective structured assessment (OSA) using visual and kinesthetic resources with minimal use of written resources. We studied the impact of STIs on caregivers' knowledge and practical skills and the rate of peritonitis.

METHODS

This prospective study conducted initial STI (iSTI) for caregivers of children initiating PD and retraining STI (rSTI) for those already on PD. OSA was administered after completion of training, and those scoring < 95% were retrained. Re-assessment was done at 3, 6, and 12 months, and those who scored < 95% underwent re-training. The rate of PD peritonitis and the time to first peritonitis were compared between the STI group and the cohort on PD in our center who received standard training before STI (controls).

RESULTS

Caregivers of 40 children were included. The median duration of iSTI and rSTI was 19.5 (18, 20) and 9 (9, 9.5) hrs, and the OSA scores were 97% (97%, 98%) and 96% (96%, 98%), respectively. Only 5% required retraining. There was a significant reduction in the rate of PD peritonitis (0.29 vs. 0.69 episodes/patient-year; p < 0.001) and longer time to peritonitis (189 vs. 69 days; p < 0.001) in the STI group when compared to the controls (n = 32).

CONCLUSIONS

STI was effective in training caregivers for peritoneal dialysis. There was a reduction in the rate of peritonitis and a longer time to first peritonitis in the STI cohort.

Educational interventions and identification of risk factors to prevent and reduce peritonitis in peritoneal dialysis: A scoping review

BACKGROUND

Peritonitis is a common and serious complication of peritoneal dialysis and is one of the main causes of peritoneal dialysis technique failure and long-term hemodialysis conversion.

OBJECTIVES

The aim of the review was to identify and clarify peritonitis risk factors and learn about strategies employed at international level to prevent and reduce the occurrence of peritoneal dialysis associated infections and their complications.

DESIGN

A scoping review.

PARTICIPANTS

Adults in pertitoneal dialysis.

MEASUREMENTS

The methodology framework of Arksey and O'Malley and PRISMA for Scoping Reviews guidelines were applied. A search was conducted of PubMed, Scopus and CINAHL using terms to identify peritoneal dialysis -associated risk factors and interventions carried out for the prevention and reduction of peritonitis in adult persons living at home.

RESULTS

The 17 studies selected were based on work carried out in nine different countries. Eleven articles analysed modifiable risk factors (low educational level, being a foreigner and low adherence to aseptic technique) and non-modifiable risk factors (age and comorbidities) that predispose to peritonitis in peritoneal dialysis. The other six studies applied an intervention to improve the prevalence of peritonitis considering educational practices adapted to patient characteristics and the application of retraining.

CONCLUSIONS

Personalised patient training and the identification of risk factors for peritonitis are key to reducing complications and enhancing the survival of peritoneal dialysis patients and the effectiveness of the technique.

Pediatric peritoneal dialysis training program and its relationship to peritonitis: a study of the International Pediatric Peritoneal Dialysis Network

BACKGROUND

The guidelines for training of patients and caregivers to perform home peritoneal dialysis (PD) uniformly include recommendations pertaining to the prevention of peritonitis. The objective of this study conducted by the International Pediatric Peritoneal Dialysis Network (IPPN) was to investigate the training practices for pediatric PD and to evaluate the impact of these practices on the peritonitis and exit-site infection (ESI) rate.

METHODS

A questionnaire regarding details of the PD program and training practices was distributed to IPPN member centers, while peritonitis and ESI rates were either derived from the IPPN registry or obtained directly from the centers. Poisson univariate and multivariate regression was used to determine the training-related peritonitis and ESI risk factors.

RESULTS

Sixty-two of 137 centers responded. Information on peritonitis and ESI rates were available from fifty centers. Training was conducted by a PD nurse in 93.5% of centers, most commonly (50%) as an in-hospital program. The median total training time was 24 hours, with a formal assessment conducted in 88.7% and skills demonstration in 71% of centers. Home visits were performed by 58% of centers. Shorter (< 20 hours) training duration and lower number of training tools (both p < 0.02) were associated with higher peritonitis rate, after adjustment for proportion of treated infants and income of country of residence.

CONCLUSIONS

An association between training duration and the number of training tools represent potentially modifiable risk factors to reduce peritonitis rates within the pediatric PD population. A higher resolution version of the Graphical abstract is available as Supplementary information.

Retraining programme for older patients undergoing peritoneal dialysis: A randomised controlled trial

BACKGROUND

Peritonitis is a common cause of hospitalisation and death among patients undergoing peritoneal dialysis. Periodic retraining is recommended to prevent peritonitis, especially in older adults.

OBJECTIVES

We evaluated the effectiveness of a retraining programme for reducing peritonitis and exit site infection rates in older adults on peritoneal dialysis. The cost-benefit ratio was also calculated.

DESIGN

A two-arm prospective randomised controlled trial.

PARTICIPANTS

One hundred and thirty patients aged 55 years or older were recruited. Participants were randomly assigned to the intervention or control group. While both groups received usual care, the intervention group received a retraining programme (a knowledge and practical assessment and a one-on-one retraining session) 90 days after starting home-based continuous ambulatory peritoneal dialysis therapy.

MEASUREMENTS

The outcomes included peritonitis rate, exit site infection rate and direct medical costs at 180, 270, and 360 days after starting home-based continuous ambulatory peritoneal dialysis therapy.

RESULTS

No significant differences were found in the baseline characteristics between groups. The peritonitis rates were 0.11 episodes per patient-year in the intervention group versus 0.13 in the control group. The incidence of exit site infection was 20.0% in the intervention group and 12.3% in the control group. The cost-benefit ratio of retraining was 1:9.6. None of the results were statistically significant.

CONCLUSIONS

The absence of statistical significance may be partly explained by the premature termination of the study. Large-scale multi-centre trials are warranted to examine the effectiveness of retraining. The timing and long-term effects of retraining also need to be examined.

Peritoneal Dialysis Patient Training Program to Enhance independence and Prevent Complications: A Scoping Review

Background

Peritoneal dialysis (PD) training is essential to ensure patient independence and prevent life-threatening complications, such as peritonitis. The International Society for Peritoneal Dialysis (ISPD) recommends that every PD unit worldwide implement local PD training programs with the goal of improving self-care capabilities. This scoping review aims to give an overview of recent literature and recommendations on PD training programs aiming to improve the quality of care and outcomes for PD patients.

Methods

The literature search was conducted using the PC (Population, Concept) approach. The population of interest in this study is PD patients, and the study concept is the PD training program. Several databases were used to conduct the literature search, including PubMed, Science Direct, and CINAHL. The search process began from July 2022 until January 2023. The inclusion criteria for the search included research articles and recommendations.

Results

The search yielded 22 articles recommending training programs lasting from 5-8 days, with 1-3-hour sessions and a nurse-to-patient ratio of 1:1. A cumulative training time of 15 hours or more is recommended to enhance patient independence and reduce peritonitis rates. Home-based or in-unit PD training, conducted by experienced nurses using adult learning strategies, has shown significant value in improving self-care and preventing peritonitis. Evaluating training outcomes should encompass knowledge, skills, and attitudes, and the impact on peritonitis rates. Training programs should be flexible and consider physiological and psychosocial barriers to achieving the best results.

Conclusion

There are a variety of strategies for dialysis training concerning duration, session length, patient-to-trainer ratio, timing, methods, location, compliance, and the need for retraining. More evidence is needed to assess the impact of PD patient training programs on self-care capabilities and peritonitis incidence. Future studies should investigate the effects of training programs on compliance, self-efficacy, and patient and nurse perspectives.

Utilization of Home Dialysis and Permanent Vascular Access at Dialysis Initiation Following a Structured CKD Education Program

Rationale & Objective

Treatment options for kidney failure are complex, and the majority of patients transitioning to dialysis lack important information about treatment options and are not prepared to make informed decisions about their care. Correspondingly, the majority of patients who start dialysis default to in-center hemodialysis using a central venous catheter for vascular access as the initial modality; furthermore, hospital admissions, mortality, and infections are exceedingly common over the first few months.

Study Design

Matched retrospective cohort study.

Setting & Patients

2,398 adult patients with chronic kidney disease (CKD) who attended a structured CKD education program and pair-matched control patients who did not receive education before starting dialysis between January 2018 and June 2019.

Exposure

CKD education attendance documented from 2 months (60 days)-3 years before dialysis initiation. CKD education consisted of a 1-time, 90-minute, inperson or virtual class.

Outcome

Primary outcomes were dialysis modality and vascular access type on the first day of dialysis (day 0) and at day 90 after dialysis initiation. Secondary outcomes included hospitalizations and deaths during the first year of receiving dialysis.

Analytical Approach

Generalized linear models were used to compare outcomes between patients receiving CKD education and controls.

Results

Compared with controls, CKD education patients were more frequently receiving home dialysis (38.5% vs 12.6%, P < 0.001) and used a permanent vascular access (57.9% vs 33.8%, P < 0.001) at dialysis initiation; differences were minimally attenuated and remained statistically significant at day 90. Hospitalization rates were lower among CKD education patients than among controls during the first year of receiving dialysis (1.00 vs 1.38 admissions per patient-year; P < 0.001). CKD education patients also had lower mortality over the first year of receiving dialysis (P < 0.001).

Limitations

Bias and confounding cannot fully be accounted for in an observational study. Analyses only included patients with commercial and Medicare insurance who received CKD care before dialysis initiation and may not be generalizable to other patient populations.

Conclusions

Our findings indicate that attending a CKD education class before starting dialysis resulted in positive clinical outcomes, including reduction in hospitalization and mortality rates. Broad implementation of structured CKD education may result in more patients choosing home dialysis as their first treatment option and reduce the risk of adverse outcomes in the crucial early period after dialysis initiation.

International peritoneal dialysis training practices and the risk of peritonitis

BACKGROUND

The effects of training practices on outcomes of patients receiving peritoneal dialysis (PD) are poorly understood and there is a lack of evidence informing best training practices. This prospective cohort study aims to describe and compare international PD training practices and their association with peritonitis.

METHODS

Adult patients on PD < 3 months participating in the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) were included. Training characteristics (including duration, location, nurse affiliation, modality, training of family members, use of individual/group training, and use of written/oral competency assessments) were reported at patient and facility levels. Hazard ratio for time to first peritonitis was estimated using Cox models, adjusted for selected patient and facility case-mix variables.

RESULTS

1376 PD patients from 120 facilities across 7 countries were included. Training was most commonly performed at the facility (81%), by facility-affiliated nurses (87%) in a 1:1 setting (79%). In the UK, being trained by both facility and third-party nurses was associated with reduced peritonitis risk (aHR 0.31, 95% CI 0.15-0.62, vs facility nurses only). However, this training practice was utilized in only 5 of 14 UK facilities. No other training characteristics were convincingly associated with peritonitis risk.

CONCLUSIONS

There was no evidence to support that peritonitis risk was associated with when, where, how, or how long PD patients are trained.

Structured re-training to reduce peritonitis in a pediatric peritoneal dialysis program: a quality improvement intervention

BACKGROUND

Decline in skills and knowledge among patients and/or caregivers contributes to peritoneal-dialysis (PD)-related peritonitis. Re-training is important, but no guidelines exist. We describe the implementation of a structured re-training program to decrease peritonitis rates.

METHODS

This is a prospective quality improvement study involving pediatric patients on long-term home automated PD at National University Hospital, Singapore, between 2012 and 2018. With increasing peritonitis rates, systematic root cause analysis was performed, and based on the contributory factors identified, a structured re-training program was implemented from 2015. This was conducted in 5 cycles, each consisting of 4 modules (hand hygiene, exit site care, peritonitis, and PD troubleshooting).

RESULTS

Peritonitis rates were analyzed in 2 phases: Phase 1 (2012-2014) when no re-training was performed and Phase 2 (2016-2018) after re-training was instituted. Fifty-nine patients were included. Of these, 45 patients were in Phase 1, 32 in Phase 2, and 18 in both phases. Peritonitis rates decreased from 0.37 ± 0.67 episodes per patient-year in Phase 1 to 0.13 ± 0.32 episodes per patient-year in Phase 2. After adjusting for age at kidney failure onset, PD vintage, years of nursing experience, and the average patient-to-nurse ratio over the study period for each patient, the adjusted peritonitis rates decreased by 0.38 episodes per patient-year (95% CI, 0.09 to 0.67, p = 0.011) from Phase 1 to Phase 2.

CONCLUSION

Despite an improvement in staffing ratio, peritonitis rates only improved significantly after intensive structured re-training was instituted.

Trends in Peritoneal Dialysis Technique Survival, Death, and Transfer to Hemodialysis: A Decade of Data from the RDPLF

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.

Meaning of empowerment in peritoneal dialysis: focus groups with patients and caregivers

BACKGROUND

While peritoneal dialysis (PD) can offer patients more independence and flexibility compared with in-center hemodialysis, managing the ongoing and technically demanding regimen can impose a burden on patients and caregivers. Patient empowerment can strengthen capacity for self-management and improve treatment outcomes. We aimed to describe patients' and caregivers' perspectives on the meaning and role of patient empowerment in PD.

METHODS

Adult patients receiving PD (n = 81) and their caregivers (n = 45), purposively sampled from nine dialysis units in Australia, Hong Kong and the USA, participated in 14 focus groups. Transcripts were thematically analyzed.

RESULTS

We identified six themes: lacking clarity for self-management (limited understanding of rationale behind necessary restrictions, muddled by conflicting information); PD regimen restricting flexibility and freedom (burden in budgeting time, confined to be close to home); strength with supportive relationships (gaining reassurance with practical assistance, comforted by considerate health professionals, supported by family and friends); defying constraints (reclaiming the day, undeterred by treatment, refusing to be defined by illness); regaining lost vitality (enabling physical functioning, restoring energy for life participation); and personal growth through adjustment (building resilience and enabling positive outlook, accepting the dialysis regimen).

CONCLUSIONS

Understanding the rationale behind lifestyle restrictions, practical assistance and family support in managing PD promoted patient empowerment, whereas being constrained in time and capacity for life participation outside the home undermined it. Education, counseling and strategies to minimize the disruption and burden of PD may enhance satisfaction and outcomes in patients requiring PD.

Effects of educational practices on the peritonitis risk in peritoneal dialysis: a retrospective cohort study with data from the French peritoneal Dialysis registry (RDPLF)

Background

Peritoneal dialysis (PD) is a home-based therapy performed by patients or their relatives in numerous cases, and the role of patients’ educational practices in the risk of peritonitis is not well assessed. Our aim was to evaluate the effect of PD learning methods on the risk of peritonitis.

Methods

This was a retrospective multicentric study based on data from a French registry. All incident adults assisted by family or autonomous for PD exchanges in France between 2012 and 2015 were included. The event of interest was the occurrence of peritonitis. Cox and hurdle regression models were used for statistical analysis to asses for the survival free of peritonitis, and the risk of first and subsequent peritonitis.

Results

1035 patients were included. 967 (93%) received education from a specialized nurse. Written support was used for the PD learning in 907 (87%) patients, audio support in 221 (21%) patients, and an evaluation grid was used to assess the comprehension in 625 (60%) patients. In the “zero” part of the hurdle model, the use of a written support and starting PD learning with hands-on training alone were associated with a lower survival free of peritonitis (respectively HR 1.59, 95%CI 1.01–2.5 and HR 1.94, 95%CI 1.08–3.49), whereas in the “count” part, the use of an audio support and starting of PD learning with hands-on training in combination with theory were associated with a lower risk of presenting further episodes of peritonitis after a first episode (respectively HR 0.55, 95%CI 0.31–0.98 and HR 0.57, 95%CI 0.33–0.96).

Conclusions

The various PD education modalities were associated with differences in the risk of peritonitis. Prospective randomized trials are necessary to confirm causal effect. Caregivers should assess the patient’s preferred learning style and their literacy level and adjust the PD learning method to each individual.

Retraining for prevention of peritonitis in peritoneal dialysis patients: A randomized controlled trial

BACKGROUND

Peritonitis is more common in peritoneal dialysis (PD) patients nonadherent to the PD exchange protocol procedures than in compliant patients. We therefore investigated whether regular testing of PD knowledge with focus on infection prophylaxis could increase the time to first peritonitis (primary outcome) and reduce the peritonitis rate in new PD patients.

METHODS

This physician-initiated, open-label, parallel group trial took place at 57 centers in Sweden, Denmark, Norway, Finland, Estonia, Latvia, the Netherlands, and the United Kingdom from 2010 to 2015. New peritonitis-free PD patients were randomized using computer-generated numbers 1 month after the start of PD either to a control group (n = 331) treated according to center routines or to a retraining group (n = 340), which underwent testing of PD knowledge and skills at 1, 3, 6, 12, 18, 24, 30, and 36 months after PD start, followed by retraining if the goals were not achieved.

RESULTS

In all, 74% of the controls and 80% of the retraining patients discontinued the study. The groups did not differ significantly regarding cumulative incidence of first peritonitis adjusted for competing risks (kidney transplantation, transfer to hemodialysis and death; hazard ratio 0.84; 95% confidence interval (CI) 0.65-1.09) nor regarding peritonitis rate per patient year (relative risk 0.93; 95% CI 0.75-1.16).

CONCLUSIONS

In this randomized controlled trial, we were unable to demonstrate that regular, targeted testing and retraining of new PD patients increased the time to first peritonitis or reduced the rate of peritonitis, as the study comprised patients with a low risk of peritonitis, was underpowered, open to type 1 statistical error, and contamination between groups.

An Intervention Design: Supporting Skills Development for Peritoneal Dialysis Trainers

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.

Risk Factors And Prevention of Peritoneal Dialysis-Related Peritonitis

BACKGROUND

Peritonitis is a major complication and the main cause of peritoneal dialysis (PD) failure. The aim of the present study was to evaluate peritonitis risk factors and its prevention with a new peritoneal educational program (NPEP).

METHODS

We performed a retrospective analysis of a cohort of chronic PD patients, older than 16 years, who began PD in the period 1 January 1999 to 31 December 2015 at a Uruguayan PD center, with follow-up until 31 December 2016.

RESULTS

The population included 222 cases (219 patients, 128 men), median age 59 (interquartile range [IQR] 47.0 - 72.0) years, median time on PD 17.5 (IQR 6.0 - 36.2) months. Ninety-five patients suffered 1 or more episodes of peritonitis, and they had been on PD for a longer period and had nasal-positive culture more frequently. A NPEP started in September 2008; patients who trained with it, as well as younger patients, had longer peritonitis-free survival. After the NPEP, global peritonitis rates decreased significantly (from 0.48 to 0.29 episodes/patient-year, respectively), particularly gram-positive bacteria and Staphylococcus aureus / coagulase-negative (CoNS) (from 0.26 to 0.12 and 0.21 to 0.07 episodes/patient-year, respectively). In the multivariate Cox analysis of peritonitis risk factors, survival to first peritonitis was significantly associated only with age (hazard ratio [HR] 1.024, 95% confidence interval [CI] 1.007 - 1.397, p = 0.007) and the NPEP (HR 0.600, 95% CI 0.394 - 0.913, p = 0.017).

CONCLUSION

A multidisciplinary peritoneal educational program may improve peritonitis rates, independently of other risk factors.

Frequent patient retraining at home reduces the risks of peritoneal dialysis-related infections: A randomised study

The present study, entitled Trial on Education And Clinical outcomes for Home PD patients (TEACH), investigated the effect of frequent retraining at home on the outcomes of peritoneal dialysis (PD). TEACH is a multicentre, open-label, randomised, controlled trial with parallel arms. Patients starting PD were randomized into either the conventional retraining group (CG) or the frequent retraining group (FG). Patients in the FG were given more frequent home visits for retraining. The primary endpoint was exit site infection (ESI). Secondary endpoints were peritonitis, any PD-related infections, hospitalization, technique failure, and patient survival. A generalised estimating equations (GEE) approach was employed for the adjusted effect of training level on the outcomes. Cox regression was employed for peritonitis and other secondary outcomes. The subjects were randomised to either the FG (n = 51) or the CG (n = 53). Although the time of initial training did not differ between the 2 groups, the total time of training was longer and the frequency of training visits was higher in the FG. In the GEE model, the p-values for interactions between groups and time were significant for both ESI and any PD-related infections, suggesting that the event rates of the two groups significantly changed over time. The event rates for the FG decreased over time, and the event rates for the CG increased after month 12. In the older subgroup (age ≥ 60), frequent retraining had a significant effect in the risk reduction of the first episode of peritonitis (adjusted HR 0.01 [0.001–0.35], p = 0.01). Frequent retraining at home reduced the risk of PD-related infections.

A contemporary approach to the prevention of peritoneal dialysis-related peritonitis in children: the role of improvement science

Peritonitis is a leading cause of hospitalizations, morbidity, and modality change in pediatric chronic peritoneal dialysis (CPD) patients. Despite guidelines published by the International Society for Peritoneal Dialysis aimed at reducing the risk of peritonitis, registry data have revealed significant variability in peritonitis rates among centers caring for children on CPD, which suggests variability in practice. Improvement science methods have been used to reduce a variety of healthcare-associated infections and are also being applied successfully to decrease rates of peritonitis in children. A successful quality improvement program with the goal of decreasing peritonitis will not only include primary drivers directly linked to the outcome of peritonitis, but will also direct attention to secondary drivers that are important for the achievement of primary drivers, such as health literacy and patient and family engagement strategies. In this review, we describe a comprehensive improvement science model for the reduction of peritonitis in pediatric patients on CPD.

Psychosocial Factors Predict Nonadherence to PD Treatment: A Hong Kong Survey

Background

Nonadherence to hand hygiene and aseptic regimen, dialysis environment guidelines, and catheter and exit-site care guidelines are risk factors of peritonitis. However, little is known about the psychosocial factors that account for the nonadherent behavior of patients undergoing peritoneal dialysis (PD). Applying the health belief model, this study seeks to enhance the understanding of psychosocial influences on patients’ nonadherent behavior to the 3 regimen components.

Methods

Through referrals by 7 Hong Kong renal patient support groups, we surveyed patients undergoing PD treatment.

Results

A total of 244 Hong Kong PD patients completed the questionnaires. About 90% of the patients reported no deviation from catheter and exit-site care guidelines. However, the nonadherence rates of hand hygiene and aseptic regimen and of dialysis environment guidelines were 30.3% and 23%, respectively. Longer time on PD treatment and lower family monthly income were associated with nonadherence to dialysis environment guidelines. Employed patients tended toward nonadherence to catheter and exit-site care guidelines twice as much as unemployed patients. Of the 5 health beliefs, perceived benefits, perceived barriers, and efficacy belief were significant predictors of nonadherence to the 3 regimen components.

Conclusions

The findings of this study inform the design of intervention to change patients’ behavior in regimen nonadherence for preventing peritonitis. To identify the target audience for adherence intervention based on the 3 regimen components, the results suggest dividing patients into subgroups according to their sociodemographic background. To foster behavioral change, health communicators should address patients’ health beliefs when formulating intervention strategies.

The Current State of Peritoneal Dialysis

Technical innovations in peritoneal dialysis (PD), now used widely for the long-term treatment of ESRD, have significantly reduced therapy-related complications, allowing patients to be maintained on PD for longer periods. Indeed, the survival rate for patients treated with PD is now equivalent to that with in-center hemodialysis. In parallel, changes in public policy have spurred an unprecedented expansion in the use of PD in many parts of the world. Meanwhile, our improved understanding of the molecular mechanisms involved in solute and water transport across the peritoneum and of the pathobiology of structural and functional changes in the peritoneum with long-term PD has provided new targets for improving efficiency and for intervention. As with hemodialysis, almost half of all deaths on PD occur because of cardiovascular events, and there is great interest in identifying modality-specific factors contributing to these events. Notably, tremendous progress has been made in developing interventions that substantially reduce the risk of PD-related peritonitis. Yet the gains have been unequal among individual centers, primarily because of unequal clinical application of knowledge gained from research. The work to date has further highlighted the areas in need of innovation as we continue to strive to improve the health and outcomes of patients treated with PD.

The Needs of Older Patients for Peritoneal Dialysis: Training and Support at Home

Chronic kidney disease (CKD) in all its stages has become an important problem for older patients, stage 3 - 5 is expected to happen in 25 to 30% of the population, and a higher prevalence can be found in residential care and nursing homes, affecting the demand for patient education. Although older patients are able and keen to learn, there are specific needs that must be addressed. The focus of this paper is to review the demands to train and maintain older patients on peritoneal dialysis (PD) at home.

Educational strategies and challenges in peritoneal dialysis: a qualitative study of renal nurses' experiences

AIMS AND OBJECTIVES

The aim of the study was to explore renal nurses' experiences, strategies and challenges with regard to the patient education process in peritoneal dialysis.

BACKGROUND

Patient education in peritoneal dialysis is essential to developing a successful home-based peritoneal dialysis program. In this area research is scarce and there is a particular lack of focus on the perspective of the renal nurse.

DESIGN

Qualitative design formed by thematic qualitative text analysis.

METHODS

Five group interviews (n = 20) were used to explore the challenges peritoneal dialysis nurses face and the training strategies they use. The interviews were analyzed with thematic qualitative content analysis using deductive and inductive subcategory application.

RESULTS

The findings revealed the education barriers perceived by nurses that patients may face. They also showed that using assessment tools is important in peritoneal dialysis patient education, as is developing strategies to promote patient self-management. There is a need for a deeper understanding of affective learning objectives, and existing teaching activities and materials should be revised to incorporate the patient's perspective. Patients usually begin having questions about peritoneal dialysis when they return home and are described as feeling overwhelmed. Adapting existing conditions is considered a major challenge for patients and nurses.

CONCLUSIONS

The results provided useful insights into the best approaches to educating peritoneal dialysis patients and served to raise awareness of challenges experienced by renal nurses. Findings underline the need for nosogogy - an approach of teaching adults (andragogy) with a chronic disease. Flexibility and cooperation are competencies that renal nurses must possess.

RELEVANCE TO CLINICAL PRACTICE

Still psychomotor skills dominate peritoneal dialysis patient training, there is a need of both a deeper understanding of affective learning objectives and the accurate use of (self-)assessment tools, particularly for health literacy.

Focus on peritoneal dialysis training: working to decrease peritonitis rates

Patient training has widely been considered to be one of the most critical factors for achieving optimal peritoneal dialysis clinical outcomes, including avoidance of peritonitis. However, research in this important area has been remarkably scant to date. This article will critically review the clinical evidence underpinning PD patient training and will specifically focus on four key areas: who should provide training and how, when and where should it be performed to obtain the best results. Evidence gaps and future research directions will also be discussed.

Peritoneal dialysis-related peritonitis: towards improving evidence, practices, and outcomes

Peritonitis is a common serious complication of peritoneal dialysis that results in considerable morbidity, mortality, and health care costs. It also significantly limits the use of this important dialysis modality. Despite its importance as a patient safety issue, peritonitis practices and outcomes vary markedly and unacceptably among different centers, regions, and countries. This article reviews peritonitis risk factors, diagnosis, treatment, and prevention, particularly focusing on potential drivers of variable practices and outcomes, controversial or unresolved areas, and promising avenues warranting further research. Potential strategies for augmenting the existing limited evidence base and reducing the gap between evidence-based best practice and actual practice also are discussed.

Prevention of peritonitis in peritoneal dialysis

Reducing the frequency of peritonitis for patients undergoing peritoneal dialysis (PD) continues to be a challenge. This review focuses on recent updates in catheter care and other patient factors that influence infection rates. An experienced nursing staff plays an important role in teaching proper PD technique to new patients, but nursing staff must be cognizant of each patient's unique educational needs. Over time, many patients become less adherent to proper dialysis technique, such as washing hands or wearing a mask. This behavior is associated with higher risk of peritonitis and is modifiable with re-training. Prophylactic antibiotics before PD catheter placement can decrease the infection risk immediately after catheter placement. In addition, some studies suggest that prophylaxis against fungal superinfection after antibiotic exposure is effective in reducing fungal peritonitis, although larger randomized studies are needed before this practice can be recommended for all patients. Over time, exit site and nasal colonization with pathogenic organisms can lead to exit-site infections and peritonitis. For patients with Staphylococcus aureus colonization, exit-site prophylaxis with either mupirocin or gentamicin cream reduces clinical infection with this organism. Although there are limited data for support, antibiotic prophylaxis before gastrointestinal, gynecologic, or dental procedures may also help reduce the risk of peritonitis.

[Peritoneal dialysis from the beginnings up to today: which developments of the last decades were important?]

During the past years new developments in peritoneal dialysis (PD) technique have resulted in continuous improvement of patient outcome. The importance of salt and fluid balance, residual renal function and peritoneal glucose load are of increasing interest, whereas small solute clearances have lost importance. In patients with high peritoneal transport rates automated PD (APD) is indicated. However, APD can also be chosen as initial PD treatment since recent studies show comparable or even better survival as compared to continuous ambulatory PD patients. Alternative PD solutions improve peritoneal ultrafiltration (icodextrin), reduce peritoneal glucose load (amino acid solution, icodextrin) and protect the peritoneal membrane (solutions with low concentration of glucose degradation products). Infection risk can be reduced when using antibiotic creams, but resistances should be considered. Ongoing studies will clarify if non-antibiotic agents, e.g. medihoney, are effective in preventing PD-associated infections. Due to these improvements PD and hemodialysis have become equivalent treatments.
