Good practices for dialysis education, treatment, and eHealth: A scoping review

Decision-Making Engagement Preferences among Older Adults with CKD

Key Points

Clinicians’ uncertainty about the degree to which older patients prefer to engage in decision making remains a key barrier to shared decision making. Most older adults with advanced CKD preferred a collaborative or active role in decision making.

Background

Older adults with kidney failure face preference-sensitive decisions regarding dialysis initiation. Despite recommendations, few older patients with kidney failure experience shared decision making. Clinician uncertainty about the degree to which older patients prefer to engage in decision making remains a key barrier.

Methods

This study follows a mixed-methods explanatory, longitudinal, sequential design at four diverse US centers with patients (English-fluent, aged ≥70 years, CKD stages 4–5, nondialysis) from 2018 to 2020. Patient preferences for engagement in decision making were assessed using the Control Preferences Scale, reflecting the degree to which patients want to be involved in their decision making: active (the patient prefers to make the final decision), collaborative (the patient wants to share decision making with the clinician), or passive (the patient wants the clinician to make the final decision) roles. Semistructured interviews about engagement and decision making were conducted in two waves (2019, 2020) with purposively sampled patients and clinicians. Descriptive statistics and ANOVA were used for quantitative analyses; thematic and narrative analyses were used for qualitative data.

Results

Among 363 patient participants, mean age was 78±6 years, 42% were female, and 21% had a high school education or less. Control Preferences Scale responses reflected that patients preferred to engage actively (48%) or collaboratively (43%) versus passively (8%). Preferred roles remained stable at 3-month follow-up. Seventy-six participants completed interviews (45 patients, 31 clinicians). Four themes emerged: control preference roles reflect levels of decisional engagement; clinicians control information flow, especially about prognosis; adapting a clinical approach to patient preferred roles; and clinicians' responsiveness to patient preferred roles supports patients' satisfaction with shared decision making.

Conclusions

Most older adults with advanced CKD preferred a collaborative or active role in decision making. Appropriately matched information flow with patient preferences was critical for satisfaction with shared decision making.

The experiences of people starting haemodialysis: A qualitative study

BACKGROUND AND OBJECTIVE

Starting dialysis is a life-changing transition for people living with kidney disease. People feel overwhelmed with diet changes, medications and surgical interventions, and often experience high levels of anxiety, depression and hospital admissions. The objective of this study was to explore and describe the experiences and perspectives of people starting dialysis.

STUDY DESIGN

Observational qualitative study using audio-recorded, individual, semi-structured interviews.

PARTICIPANTS

We conducted 20 semi-structured interviews with English-speaking adults who were within 90 days of starting in-centre haemodialysis at centres of a nonprofit dialysis provider in Northern California.

APPROACH

Trained qualitative researchers conducted interviews that were deidentified and transcribed verbatim before being inductively coded into codes, categories, and themes.

RESULTS

Three overarching themes emerged from the interviews. Being overwhelmed when starting dialysis, realises the emotional unpreparedness of patients starting dialysis and how the centre's environment (waiting and treatment areas) and staff behaviour impact the dialysis start experience. Making sense of it all, covers how the patient's symptoms, behaviour, and dialysis-related experiences impact the dialysis start. Moving forward, describes how education informed optimal decision-making, and can provide hope for a longer and better life.

LIMITATIONS

Predominantly college-educated participants were recruited from a single dialysis organisation which may limit the transferability of results.

CONCLUSION

Understanding the life-changing experiences that patients encounter when starting dialysis assist dialysis clinicians to help patients adjust and develop long-term coping strategies.

Functionality and Usability of mHealth Apps in Patients with Peritoneal Dialysis: A Systematic Review

mHealth has been utilized in the care of patients with chronic kidney disease, allowing the collection of patient health-related data, offering disease-related information, enabling the tracking and recording of biochemical parameters, and enabling communication with healthcare providers in real time through applications. mHealth may improve the health outcomes in patients with peritoneal dialysis. This systematic review aimed to summarize evidence regarding the functionality and usability of mHealth apps in patients with peritoneal dialysis. We conducted a comprehensive literature review, searching in five databases, including CINAHL, Cochrane, PsycINFO, PubMed, and Web of Science, to retrieve titles and abstracts related to peritoneal dialysis and mHealth applications for PRISMA recommendations from January 2013 to December 2023. Overall, 11 studies met all the inclusion criteria. The functionality of mHealth apps included inform, instruct, record, display, guide, remind/alert, and communicate. Most of the apps have multifunctionality. The usability was categorized into three aspects: efficiency (self-efficacy and usability), satisfaction, and effectiveness (underwent kidney transplantation and switched to hemodialysis, rehospitalization, peritonitis rate, infection rates at exit sites, mortality, fluid overload, inadequate solute clearance, biochemical values, quality of life, consumer quality index, and technology readiness). Generally, outcomes in the intervention group had better effects compared to those in the control group. Multifunctional mHealth apps show a good potential in improving the efficiency, satisfaction, and effectiveness for patients compared to traditional care. Future research should include more studies and participants to explore and verify the long-term effectiveness of mHealth apps.

Evaluating the Effects of Kidney Preservation at 10 °C with Hemopure and Sodium Thiosulfate in a Rat Model of Syngeneic Orthotopic Kidney Transplantation

Kidney transplantation is preferred for end-stage renal disease. The current gold standard for kidney preservation is static cold storage (SCS) at 4 °C. However, SCS contributes to renal graft damage through ischemia-reperfusion injury (IRI). We previously reported renal graft protection after SCS with a hydrogen sulfide donor, sodium thiosulfate (STS), at 4 °C. Therefore, this study aims to investigate whether SCS at 10 °C with STS and Hemopure (blood substitute), will provide similar protection. Using in vitro model of IRI, we subjected rat renal proximal tubular epithelial cells to hypoxia-reoxygenation for 24 h at 10 °C with or without STS and measured cell viability. In vivo, we preserved 36 donor kidneys of Lewis rats for 24 h in a preservation solution at 10 °C supplemented with STS, Hemopure, or both followed by transplantation. Tissue damage and recipient graft function parameters, including serum creatinine, blood urea nitrogen, urine osmolality, and glomerular filtration rate (GFR), were evaluated. STS-treated proximal tubular epithelial cells exhibited enhanced viability at 10 °C compared with untreated control cells (p < 0.05). Also, STS and Hemopure improved renal graft function compared with control grafts (p < 0.05) in the early time period after the transplant, but long-term function did not reach significance. Overall, renal graft preservation at 10 °C with STS and Hemopure supplementation has the potential to enhance graft function and reduce kidney damage, suggesting a novel approach to reducing IRI and post-transplant complications.

Normal Proteasome Function Is Needed to Prevent Kidney Graft Injury during Cold Storage Followed by Transplantation

Kidney transplantation is the preferred treatment for end-stage kidney disease (ESKD). However, there is a shortage of transplantable kidneys, and donor organs can be damaged by necessary cold storage (CS). Although CS improves the viability of kidneys from deceased donors, prolonged CS negatively affects transplantation outcomes. Previously, we reported that renal proteasome function decreased after rat kidneys underwent CS followed by transplantation (CS + Tx). Here, we investigated the mechanism underlying proteasome dysfunction and the role of the proteasome in kidney graft outcome using a rat model of CS + Tx. We found that the key proteasome subunits β5, α3, and Rpt6 are modified, and proteasome assembly is impaired. Specifically, we detected the modification and aggregation of Rpt6 after CS + Tx, and Rpt6 modification was reversed when renal extracts were treated with protein phosphatases. CS + Tx kidneys also displayed increased levels of nitrotyrosine, an indicator of peroxynitrite (a reactive oxygen species, ROS), compared to sham. Because the Rpt6 subunit appeared to aggregate, we investigated the effect of CS + Tx-mediated ROS (peroxynitrite) generation on renal proteasome assembly and function. We treated NRK cells with exogenous peroxynitrite and evaluated PAC1 (proteasome assembly chaperone), Rpt6, and β5. Peroxynitrite induced a dose-dependent decrease in PAC1 and β5, but Rpt6 was not affected (protein level or modification). Finally, serum creatinine increased when we inhibited the proteasome in transplanted donor rat kidneys (without CS), recapitulating the effects of CS + Tx. These findings underscore the effects of CS + Tx on renal proteasome subunit dysregulation and also highlight the significance of proteasome activity in maintaining graft function following CS + Tx.

Challenges in the Care of Patients with AKI Receiving Outpatient Dialysis: AKINow Recovery Workgroup Report

BACKGROUND

Up to one third of survivors of AKI that required dialysis (AKI-D) during hospitalization remain dialysis dependent at hospital discharge. Of these, 20%-60%, depending on the clinical setting, eventually recover enough kidney function to stop dialysis, and the remainder progress to ESKD.

METHODS

To describe the challenges facing those still receiving dialysis on discharge, the AKINow Committee conducted a group discussion comprising 59 participants, including physicians, advanced practitioners, nurses, pharmacists, and patients. The discussion was framed by a patient who described gaps in care delivery at different transition points and miscommunication between care team members and the patient.

RESULTS

Group discussions collected patient perspectives of ( 1 ) being often scared and uncertain about what is happening to and around them and ( 2 ) the importance of effective and timely communication, a comfortable physical setting, and attentive and caring health care providers for a quality health care experience. Provider perspectives included ( 1 ) the recognition of the lack of evidence-based practices and quality indicators, the significant variability in current care models, and the uncertain reimbursement incentives focused on kidney recovery and ( 2 ) the urgency to address communication barriers among hospital providers and outpatient facilities.

CONCLUSIONS

The workgroup identified key areas for future research and policy change to ( 1 ) improve communication among hospital providers, dialysis units, and patients/care partners; ( 2 ) develop tools for risk classification, subphenotyping, and augmented clinical decision support; ( 3 ) improve education to providers, staff, and patients/care partners; ( 4 ) identify best practices to improve relevant outcomes; ( 5 ) validate quality indicators; and ( 6 ) assess the effect of social determinants of health on outcomes. We urge all stakeholders involved in the process of AKI-D care to align goals and work together to fill knowledge gaps and optimize the care to this highly vulnerable patient population.

Patient engagement during the transition from nondialysis-dependent chronic kidney disease to dialysis: A meta-ethnography

INTRODUCTION

Patient engagement, encompassing both patient experience and opportunities for involvement in care, has been associated with increased patient satisfaction and the overall quality of care. Despite its importance, there is limited knowledge regarding patient engagement in the transition from nondialysis-dependent chronic kidney disease (CKD) to dialysis-dependent treatment. This systematic review employs meta-ethnography to synthesize findings from qualitative studies examining patients' experiences of engagement during this transition, with the aim of developing a comprehensive theoretical understanding of patient engagement in the transition from nondialysis-dependent CKD to dialysis.

METHODS

A systematic search of six databases, namely the Cochrane Library, PsycINFO, Scopus, Embase, PubMed and Web of Science was conducted to identify eligible articles published between 1990 and 2022. Meta-ethnography was utilized to translate and synthesize the findings and develop a novel theoretical interpretation of 'patient engagement' during the transition to dialysis.

RESULTS

A total of 24 articles were deemed eligible for review, representing 21 studies. Patient engagement during a transition to dialysis was found to encompass three major domains: psychosocial adjustment, decision-making and engagement in self-care. These three domains could be experienced as an iterative and mutually reinforcing process, guiding patients toward achieving control and proficiency in their lives as they adapt to dialysis. Additionally, patient engagement could be facilitated by factors including patients' basic capability to engage, the provision of appropriate education, the establishment of supportive relationships and the alignment with values and resources.

CONCLUSIONS

The findings of this review underscore the necessity of involving patients in transitional dialysis care, emphasizing the need to foster their engagement across multiple domains. Recommendations for future interventions include the provision of comprehensive support to enhance patient engagement during this critical transition phase. Additional research is warranted to explore the effects of various facilitators at different levels.

PATIENT OR PUBLIC CONTRIBUTION

The studies included in our review involved 633 participants (547 patients, 14 family members, 63 healthcare providers and 9 managers). Based on their experiences, views and beliefs, we developed a deeper understanding of patient engagement and how to foster it in the future.

The Optimization of Renal Graft Preservation Temperature to Mitigate Cold Ischemia-Reperfusion Injury in Kidney Transplantation

Renal transplantation is the preferred treatment for patients with end-stage renal disease. The current gold standard of kidney preservation for transplantation is static cold storage (SCS) at 4 °C. However, SCS contributes to renal ischemia-reperfusion injury (IRI), a pathological process that negatively impacts graft survival and function. Recent efforts to mitigate cold renal IRI involve preserving renal grafts at higher or subnormothermic temperatures. These temperatures may be beneficial in reducing the risk of cold renal IRI, while also maintaining active biological processes such as increasing the expression of mitochondrial protective metabolites. In this review, we discuss different preservation temperatures for renal transplantation and pharmacological supplementation of kidney preservation solutions with hydrogen sulfide to determine an optimal preservation temperature to mitigate cold renal IRI and enhance renal graft function and recipient survival.
