Peritoneal dialysis (PD) technique training: what features influence learning time?

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.

The association between embedded catheter implantation and hospitalization costs for peritoneal dialysis initiation: a retrospective cohort study

BACKGROUND

Compared with the conventional peritoneal dialysis (PD) catheter insertion, embedding PD catheter implantation is one of the procedures for planned PD initiation. However, facilities where embedded PD catheter implantation is available are limited, and the impact of embedded PD catheter implantation on hospitalization cost and length of hospitalization is unknown.

METHODS

This retrospective single-center cohort study included 132 patients with PD initiation between 2005 and 2020. The patients were divided into two groups: 64 patients in the embedding group and 68 patients in the conventional insertion group. We created a multivariable generalized linear model (GLM) with the gamma family and log-link function to evaluate the association among catheter embedding, the duration and medical costs of hospitalization for PD initiation. We also evaluated the effect modification between age and catheter embedding.

RESULTS

Catheter embedding (β coefficient - 0.13 [95% confidence interval - 0.21, - 0.05]) and age (per 10 years 0.08 [0.03, 0.14]) were significantly associated with hospitalization costs. Catheter embedding (- 0.21 [- 0.32, - 0.10]) and age (0.11 [0.03, 0.19]) were also identified as factors significantly associated with length of hospitalization. The difference between the embedding group and the conventional insertion group in hospitalization costs for PD initiation (P for interaction = 0.060) and the length of hospitalization (P for interaction = 0.027) was larger in young-to-middle-aged patients than in elderly patients.

CONCLUSIONS

Catheter embedding was associated with lower hospitalization cost and shorter length of hospitalization for PD initiation than conventional PD catheter insertion, especially in young-to-middle-aged patients.

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.

The Impact of Preoperative Risk Factors on Peritoneal Dialysis-Related Peritonitis: A Single-Center Prospective Study in Japan

Background and Objectives: Peritoneal dialysis (PD)-related peritonitis is a critical problem. However, preoperative risk factors for PD-related peritonitis have not been established. Thus, we aimed to determine the preoperative risk factors for PD-related peritonitis. Materials and Methods: This is a single-center prospective observational study. All peritonitis episodes during the study period were recorded, and preoperative and intraoperative clinical parameters were compared between patients with and without peritonitis to examine risk factors for PD-related peritonitis. Furthermore, subcutaneous and abdominal fat volumes were evaluated using computed tomography. Results: Among a total of 118 patients, 24 patients developed peritonitis. The proportion of male patients (83% vs. 61%, p = 0.04), body mass index (25 vs. 22 kg/m², p = 0.04), and subcutaneous fat area (120 vs. 102 cm², p = 0.01) were significantly higher and the proportion of patients living with family members (75% vs. 94%, p = 0.02) was significantly lower in the peritonitis group than in the non-peritonitis group. There were no significant differences in age, operation method, surgeon experience, previous abdominal surgery, medical history of diabetic nephropathy, serum albumin level, and renal function between the two groups. Conclusions: Male patients with high subcutaneous fat who are living alone might be at higher risk of PD-related peritonitis. These characteristics might be useful in risk assessment and patient education before PD induction.
