Targeted Education ApproaCH to improve Peritoneal Dialysis Outcomes (TEACH-PD): A feasibility study

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.

Multi-center, pragmatic, cluster-randomized, controlled trial of standardized peritoneal dialysis (PD) training versus usual care on PD-related infections (the TEACH-PD trial): trial protocol

BACKGROUND

Peritoneal dialysis (PD)-related infections, such as peritonitis, exit site, and tunnel infections, substantially impair the sustainability of PD. Accordingly, PD-related infection is the top-priority research outcome for patients and caregivers. While PD nurse trainers teach patients to perform their own PD, PD training curricula are not standardized or informed by an evidentiary base and may offer a potential approach to prevent PD infections. The Targeted Education ApproaCH to improve Peritoneal Dialysis outcomes (TEACH-PD) trial evaluates whether a standardized training curriculum for PD nurse trainers and incident PD patients based on the International Society for Peritoneal Dialysis (ISPD) guidelines reduces PD-related infections compared to usual training practices.

METHODS

The TEACH-PD trial is a registry-based, pragmatic, open-label, multi-center, binational, cluster-randomized controlled trial. TEACH-PD will recruit adults aged 18 years or older who have not previously undergone PD training at 42 PD treatment units (clusters) in Australia and New Zealand (ANZ) between July 2019 and June 2023. Clusters will be randomized 1:1 to standardized TEACH-PD training curriculum or usual training practice. The primary trial outcome is the time to the first occurrence of any PD-related infection (exit site infection, tunnel infection, or peritonitis). The secondary trial outcomes are the individual components of the primary outcome, infection-associated catheter removal, transfer to hemodialysis (greater than 30 days and 180 days), quality of life, hospitalization, all-cause death, a composite of transfer to hemodialysis or all-cause death, and cost-effectiveness. Participants are followed for a minimum of 12 months with a targeted average follow-up period of 2 years. Participant and outcome data are collected from the ANZ Dialysis and Transplant Registry (ANZDATA) and the New Zealand Peritoneal Dialysis (NZPD) Registry. This protocol follows the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines.

DISCUSSION

TEACH-PD is a registry-based, cluster-randomized pragmatic trial that aims to provide high-certainty evidence about whether an ISPD guideline-informed standardized PD training curriculum for PD nurse trainers and adult patients prevents PD-related infections.

Development of an instrument to assess self-management capacity of patients receiving peritoneal dialysis: CAPABLE

BACKGROUND

Treatment of kidney failure with peritoneal dialysis (PD) at home implies that the patient and/or their caregiver develop a series of skills and basic knowledge about this therapy. There is not a specific inventory of the patient's abilities to safely perform the PD procedure at home. The objective of this study was to describe the development of an instrument that allows measuring the self-management capacity of patients receiving PD, locating the performance areas that justify the need for intervention by a caregiver.

METHODS

This is a qualitative study developed in three phases: The first phase was the identification of performance areas through bibliographic search and validation of the results with focus groups of experts in PD. The second phase was the design of a system to measure self-management capacities. The third phase was a pilot test of the preliminary version of the instrument applied in 20 incident PD patients.

RESULTS

Three domains were identified to evaluate the fundamental components of self-management capacity: cognitive and sensory, each one evaluated with four items and motor domain evaluated with eight items. After applying the instrument, we found that 15 patients (75%) did not require support from the caregiver in any of the items. PD patients and nurses found the tool valuable, easy to understand and applicable in the early evaluation of a PD patient.

CONCLUSIONS

We developed an easy-to-administer instrument to measure the self-management capacity of patients receiving PD. This inventory could locate areas that require specific support from a caregiver. Planning an individualised and focused education and training process could result in better health outcomes.

Repeat exit site infection in peritoneal dialysis patient with polycythemia vera - a case report

BACKGROUND

Infectious complications of peritoneal dialysis (PD) remain a common cause of catheter loss and discontinuation of PD. Exit site infection (ESI) constitutes a significant risk factor for PD-related peritonitis and determination of predisposing states is relevant. We here present a case of repeat ESI due to Pseudomonas aeruginosa in a PD patient with skin changes in the course of polycythemia vera (PV).

CASE PRESENTATION

A 73-year-old PD patient with chronic kidney disease secondary to renal amyloidosis and ankylosing spondylitis, presented to the nephrology unit with signs of ESI. In 2006 he was diagnosed with PV and since then has was successfully treated with hydroxyurea; however, he reported recurrent episodes of developing skin nodules in the course of the disease. Exit site swab yielded Pseudomonas aeruginosa and the infection developed in the ulcerated PV nodule that appeared in exit site 2 weeks earlier. Patient was treated with intraperitoneal amikacin and oral ciprofloxacin, however, due to neurological complications, the treatment had to be interrupted and finally catheter was removed. Similar episode of ESI with Pseudomonas aeruginosa developed in the patient two years earlier and also required catheter removal.

CONCLUSION

This is the first case report demonstrating the development of ESI on the polycythemia vera skin lesion in this area. Skin manifestations of PV might be a predisposing factor to ESI in PD patients.
