Patient and caregiver involvement in a multicentre clustered hemodialysis trial

The Ottawa Statement implementation guidance document for cluster randomized trials in the hemodialysis setting

Research teams are increasingly interested in using cluster randomized trial (CRT) designs to generate practice-guiding evidence for in-center maintenance hemodialysis. However, CRTs raise complex ethical issues. The Ottawa Statement on the Ethical Design and Conduct of Cluster Randomized Trials, published in 2012, provides 15 recommendations to address ethical issues arising within 7 domains: justifying the CRT design, research ethics committee review, identifying research participants, obtaining informed consent, gatekeepers, assessing benefits and harms, and protecting vulnerable participants. But applying the Ottawa Statement recommendations to CRTs in the hemodialysis setting is complicated by the unique features of the setting and population. Here, with the help of content experts and patient partners, we co-developed this implementation guidance document to provide research teams, research ethics committees, and other stakeholders with detailed guidance on how to apply the Ottawa Statement recommendations to CRTs in the hemodialysis setting, the result of a 4-year research project. Thus, our work demonstrates how the voices of patients, caregivers, and all stakeholders may be included in the development of research ethics guidance.

The impact of logo-therapy on disease acceptance and self-awareness of patients undergoing hemodialysis; a pre-test-post-test research

BACKGROUND

Acceptance is considered a key variable in chronic diseases such as chronic renal failure. To achieve adaptation and acceptance, people face obstacles, and identifying these obstacles primarily requires self-awareness. logo-therapy can help a person achieve this goal. To this end, this study aimed to investigate the effect of logo-therapy on disease acceptance and self-awareness of patients undergoing hemodialysis referred to a medical centers supervised by Kerman medical science university in 2021.

METHODS

This quasi-experimental study was conducted with a pre-test-post-test research design on 80 patients with chronic renal failure undergoing hemodialysis in Kerman. The patients who met the inclusion criteria were selected using convenience sampling and were then randomly assigned to intervention and control groups (40 patients in each group). The logo-therapy training program was performed for the participants in the intervention group during 4 sessions of 45-60 min, individually and three times a week. The instruments used for data collection were a demographic information questionnaire, the Acceptance of Illness Scale (AIS), and the Self-Awareness Outcomes Questionnaire (SAOQ). The collected data were analyzed using SPSS software (version 22).

RESULTS

The analysis didn't show a significant difference in the acceptance of illness scores in the intervention group before and after the intervention (P > 0.05). Besides, a statistically significant difference was observed between the intervention and control groups in terms of self-awareness, indicating that the intervention improved the dialysis patients' self-awareness (P < 0.05). Also, the patients' age, marriage length, and the number of children had statistically significant correlations with self-awareness and acceptance (P < 0.05).

CONCLUSION

The results of this study showed that meaning therapy intervention can positively affect disease acceptance and self-awareness of patients undergoing hemodialysis. Since logo-therapy has been effective in other patients and the patients in this study, health officials and managers are recommended to use this intervention method to promote disease acceptance and self-awareness in these patients.

Patient-centred clinical trial design

Patient involvement in clinical trial design can facilitate the recruitment and retention of participants as well as potentially increase the uptake of the tested intervention and the impact of the findings on patient outcomes. Despite these benefits, patients still have very limited involvement in designing and conducting trials in nephrology. Many trials do not address research questions and outcomes that are important to patients, including patient-reported outcomes that reflect how patients feel and function. This limitation can undermine the relevance, reliability and value of trial-based evidence for decision-making in clinical practice and health policy. However, efforts to involve patients with kidney disease are increasing across all stages of the trial process from priority setting, to study design (including selection of outcomes and approaches to improve participant recruitment and retention) and dissemination and implementation of the findings. Harnessing the patient voice in designing trials can ensure that efforts and resources are directed towards patient-centred trials that address the needs, concerns and priorities of patients living with kidney disease with the aim of achieving transformative improvements in care and outcomes.

Pretransplant Patient Education in Solid-organ Transplant: A Narrative Review

Education for pretransplant, solid-organ recipient candidates aims to improve knowledge and understanding about the transplant process, outcomes, and potential complications to support informed, shared decision-making to reduce fears and anxieties about transplant, inform expectations, and facilitate adjustment to posttransplant life. In this review, we summarize novel pretransplant initiatives and approaches to educate solid-organ transplant recipient candidates. First, we review approaches that may be common to all solid-organ transplants, then we summarize interventions specific to kidney, liver, lung, and heart transplant. We describe evidence that emphasizes the need for multidisciplinary approaches to transplant education. We also summarize initiatives that consider online (eHealth) and mobile (mHealth) solutions. Finally, we highlight education initiatives that support racialized or otherwise marginalized communities to improve equitable access to solid-organ transplant. A considerable amount of work has been done in solid-organ transplant since the early 2000s with promising results. However, many studies on education for pretransplant recipient candidates involve relatively small samples and nonrandomized designs and focus on short-term surrogate outcomes. Overall, many of these studies have a high risk of bias. Frequently, interventions assessed are not well characterized or they are combined with administrative and data-driven initiatives into multifaceted interventions, which makes it difficult to assess the impact of the education component on outcomes. In the future, well-designed studies rigorously assessing well-defined surrogate and clinical outcomes will be needed to evaluate the impact of many promising initiatives.

Patient Partner Perspectives Regarding Ethically and Clinically Important Aspects of Trial Design in Pragmatic Cluster Randomized Trials for Hemodialysis

BACKGROUND

Cluster randomized trials (CRTs) are trials in which intact groups such as hemodialysis centers or shifts are randomized to treatment or control arms. Pragmatic CRTs have been promoted as a promising trial design for nephrology research yet may also pose ethical challenges. While randomization occurs at the cluster level, the intervention and data collection may vary in a CRT, challenging the identification of research participants. Moreover, when a waiver of patient consent is granted by a research ethics committee, there is an open question as to whether and to what degree patients should be notified about ongoing research or be provided with a debrief regarding the nature and results of the trial upon completion. While empirical and conceptual research exploring ethical issues in pragmatic CRTs has begun to emerge, there has been limited discussion with patients, families, or caregivers of patients undergoing hemodialysis.

OBJECTIVE

To explore with patients and families with experience of hemodialysis research the challenges raised by different approaches to designing pragmatic CRTs in hemodialysis. Specifically, their perceptions of (1) the use of a waiver of consent, (2) notification processes and information provided to participants, and (3) any other concerns about cluster randomized designs in hemodialysis.

DESIGN

Focus group and interview discussions of hypothetical clinical trial designs.

SETTING

Focus groups and interviews were conducted in-person or via videoconference or telephone.

PARTICIPANTS

Patient partners in hemodialysis research, defined as patients with personal experience of dialysis or a family member who had experience supporting a patient receiving hemodialysis, who have been actively involved in discussions to advise a research team on the design, conduct, or implementation of a hemodialysis trial.

METHODS

Participants were invited to participate in focus groups or individual discussions that were audio recorded with consent. Recorded interviews were transcribed verbatim prior to analysis. Transcripts were analyzed using a thematic analysis approach.

RESULTS

Two focus groups, three individual interviews, and one interview involving a patient and family member were conducted with 17 individuals between February 2019 and May 2020. Participants expressed support for approaches that emphasized patient choice. Disclosure of patient-relevant risks and information were key themes. Both consent and notification processes served to generate trust, but bypassing patient choice was perceived as undermining this trust. Participants did not dismiss the option of a waiver of consent. They were, however, more restrictive in their views about when a waiver of consent may be acceptable. Patient partners were skeptical of claims to impracticability based on costs or the time commitments for staff.

LIMITATIONS

All participants were from Canada and had been involved in the design or conduct of a trial, limiting the degree to which results may be extrapolated.

CONCLUSIONS

Given the preferences of participants to be afforded the opportunity to decide about trial participation, we argue that investigators should thoroughly investigate approaches that allow participants to make an informed choice regarding trial participation. In keeping with the preference for autonomous choice, there remains a need to further explore how consent approaches can be designed to facilitate clinical trial conduct while meeting their ethical requirements. Finally, further work is needed to define the limited circumstances in which waivers of consent are appropriate.

Major Outcomes With Personalized Dialysate TEMPerature (MyTEMP): Rationale and Design of a Pragmatic, Registry-Based, Cluster Randomized Controlled Trial

BACKGROUND

Small randomized trials demonstrated that a lower compared with higher dialysate temperature reduced the average drop in intradialytic blood pressure. Some observational studies demonstrated that a lower compared with higher dialysate temperature was associated with a lower risk of all-cause mortality and cardiovascular mortality. There is now the need for a large randomized trial that compares the effect of a low vs high dialysate temperature on major cardiovascular outcomes.

OBJECTIVE

The purpose of this study is to test the effect of outpatient hemodialysis centers randomized to (1) a personalized temperature-reduced dialysate protocol or (2) a standard-temperature dialysate protocol for 4 years on cardiovascular-related death and hospitalizations.

DESIGN

The design of the study is a pragmatic, registry-based, open-label, cluster randomized controlled trial.

SETTING

Hemodialysis centers in Ontario, Canada, were randomized on February 1, 2017, for a trial start date of April 3, 2017, and end date of March 31, 2021.

PARTICIPANTS

In total, 84 hemodialysis centers will care for approximately 15 500 patients and provide over 4 million dialysis sessions over a 4-year follow-up.

INTERVENTION

Hemodialysis centers were randomized (1:1) to provide (1) a personalized temperature-reduced dialysate protocol or (2) a standard-temperature dialysate protocol of 36.5°C. For the personalized protocol, nurses set the dialysate temperature between 0.5°C and 0.9°C below the patient's predialysis body temperature for each dialysis session, to a minimum dialysate temperature of 35.5°C.

PRIMARY OUTCOME

A composite of cardiovascular-related death or major cardiovascular-related hospitalization (a hospital admission with myocardial infarction, congestive heart failure, or ischemic stroke) captured in Ontario health care administrative databases.

PLANNED PRIMARY ANALYSIS

The primary analysis will follow an intent-to-treat approach. The hazard ratio of time-to-first event will be estimated from a Cox model. Within-center correlation will be considered using a robust sandwich estimator. Observation time will be censored on the trial end date or when patients die from a noncardiovascular event.
