Multidisciplinary Support To Access Living Donor Kidney Transplant-Pilot

Living donor kidney transplantation is the optimal treatment for end-stage kidney disease patients, dramatically improving survival and quality of life, providing significant cost saving compared with dialysis, reducing the demand for deceased donor transplants and the pressure to increase dialysis capacity and infrastructure. Outcome data shows that only 16% of Canadians on dialysis survive past 10 years, whereas up to 74% of Canadians with a kidney transplant have a functioning kidney after 10 years. The ideal treatment trajectory is to avoid dialysis entirely and receive a living donor transplant prior to dialysis (pre-emptive), which unfortunately only occurs in 10.5% of eligible patients.

Patients with end-stage kidney disease report being overwhelmed with other issues (loss of work, family stress, fear of dialysis) and lack the skills needed to comfortably engage potential living donors - many feel uncomfortable doing so and do not know how to start. The purpose of this research is to test an intervention designed to support patients identification of potential donors and communication with their social network and ultimately increase the number of living donor kidney transplantations.

Justification:

The rate of living kidney donor transplantation is lower in Alberta compared to other provinces in Canada. As the rate of kidney failure has increased over the past few years in Alberta, it is necessary to improve and facilitate the process of living kidney donor transplantation for better patient care.

Primary Objective:

The primary objective of this study is to examine the efficacy of the MuST AKT program to facilitate patients' identification of potential living kidney donors compared to usual care.

Hypothesis:

The investigators hypothesize that the MuST AKT program will increase the proportion of participants with at least one potential living kidney donors who started evaluation (intervention vs control).

Additional Objectives:

The secondary objective is to evaluate patient outcome improvement by collecting Patient Reported Outcome Measures (PROMs) to assess the proportion of patients who find at least one potential living donor.

The tertiary objective is to evaluate patient experience by collecting Patient Reported Experience Measures (PREMs) to determine whether participants recommend this program to other patients and to what extent this program gave them confidence for finding a potential living kidney donor.

The quaternary objective is to evaluate the feasibility of this program by assessing consent rate, attendance, adherence, and drop-out.

Research Methods/Procedures:

This is a pilot parallel randomized controlled trial with a qualitative interview component. The intervention condition will receive a multidisciplinary, tailored person-centered intervention over three months (MuST AKT program), and the control condition will receive the current standard of care (social worker assessment).

Patients who have been referred for kidney transplantation assessment in Edmonton will be contacted during a standard care kidney transplant education session or over the telephone if patients have completed the transplant education and are on the deceased kidney donor wait-list. Patients who expressed interest will be contacted via telephone by a member of the research team to seek their consent, complete the initial screening assessment to confirm their eligibility and enrolment, and then complete a baseline questionnaire. Then participants will be randomized to either the intervention or control condition, using predetermined randomly-generated (by Stata MP 15·1) permuted blocks of 4 and 6. Assignment to condition will be concealed by the database up until the point of assignment. Participants in the intervention condition will receive the MuST AKT program and participants in the control condition will receive usual care. Consent rate, attendance, adherence, and drop-out will be tracked during enrollment and the duration of the intervention. Upon completion of the intervention (or usual care), participants will complete a post-intervention questionnaire to assess PREMs. Participants in the intervention condition will be contacted after they have completed the post-questionnaire to participate in a qualitative interview lasting approximately 40 minutes. Kidney transplant status will be tracked for a period of 24 months post-intervention. Participants in the intervention condition who do not have a potential donor come forward after 12 months will be contacted to complete an additional interview to explore factors contributing to their lack of success, which will last approximately 40 minutes.

Intervention Condition: MuST AKT is a multidisciplinary, tailored person-centered intervention aimed to support participants identification of potential donors and communication with their social network. A one-on-one introductory session will be followed by three 'one-on-one' sessions (A, B and C) and a final session D with participants family and friends (potential donors and advocates) identified in session A. All group and individual sessions will be arranged virtually during the COVID-19 pandemic, and may be held either virtually or in-person, at the participants discretion, in the event that the COVID-19 pandemic concludes and physical distancing requirements have been eliminated. Each education session will take approximately 90 minutes. Sessions will be facilitated by a trained licensed social worker, coordinator or social media expert with extra training in kidney disease, transplantation, living kidney donation, counselling and interviewing, and patient confidentiality.

Usual care (control condition): In the control condition, participants will go through the current standard of care, which is a social worker assessment. If the intervention is successful in the definitive RCT (to be conducted later) and approved by Alberta Health Services as the 'new standard of care', people in control condition will be contacted and given the option to participate in the MuST AKT program.

Additional interviews with separate informed consent procedures:

(Patients) If, during recruitment for the study, the individual indicates they do not want to participate, or if participants drop-out of the study, a research team member will invite them participate in a 20-40 minute interview to understand barriers to participation in the study.

(Friends and family of patients) Friends and family members of participants who take part in session D will be invited to participate in an interview approximately 40 minutes long which aims to explore their experiences of group session D.

Plan for Data Analysis - Quantitative:

All analyses will be completed in Stata/MP 17.0 (www.stata.com), using an intention-to-treat approach. The investigators will use the Fisher's exact tests (dichotomous outcomes) and t-tests or Wilcoxon rank-sum tests (continuous outcomes data), as appropriate.

Our primary analyses (of our primary and secondary outcomes #1-4) will pool data from both the current and the definitive trials. In secondary analyses, the investigators will generate within trial results to investigate potential heterogeneity of intervention delivery.

Plan for Data Analysis - Qualitative Telephone interviews will be conducted using semi-structured interview guides. Data will be analyzed using a thematic analysis approach, whereby common themes that emerge from the data are documented. The qualitative software NVivo-12 will be used in the analysis.
