Feasibility and acceptability of the ShareD dEciSIon making for patients with kidney failuRE to improve end-of-life care intervention: A pilot multicentre randomised controlled trial

Abstract

Background: Kidney failure is associated with a high disease burden and high mortality rates. National and international guidelines recommend health professionals involve patients with kidney failure in making decisions about end-of-life care, but implementation of these conversations within kidney services varies. We developed the DESIRE (ShareD dEciSIon-making for patients with kidney failuRE to improve end-of-life care) intervention from our studies investigating multiple decision maker needs and experiences of end-of-life care in kidney services. The DESIRE intervention's three components are a training programme for health professionals, a patient decision aid, and a kidney service consultation held to facilitate shared decision-making conversations about planning end-of-life care. Objectives: To assess the feasibility and acceptability of integrating the DESIRE intervention within kidney services. Design: A pilot study using a multicentre randomised controlled design. Setting: Four Danish nephrology departments. Participants: Patients with kidney failure who were 75 years of age or above, their relatives, and health professionals. Methods: Patients were randomised to either the intervention or usual care. Feasibility data regarding delivering the intervention, the trial design, and outcome measures were collected through questionnaires and audio recordings at four points in time: before, during, post, and 3 months after the intervention. Acceptability data were collected through semi-structured interviews with patients and relatives, as well as a focus group with health professionals post the intervention. Results: Twenty-seven patients out of the 32 planned were randomised either to the intervention (n= 14) or usual care (n= 13). In addition, four relatives and 12 health professionals participated. Follow-up was completed by 81 % (n= 22) of patient participants. We found that both feasibility and acceptability data suggested health professionals improved their decision support and shared decision-making skills via the training. Patient and relative participants experienced the intervention as supporting a shared decision-making process; from audio recordings, we showed health professionals were able to support proactively decision-making about end-of-life care within these consultations. All stakeholders perceived the intervention to be effective in promoting shared decision-making and relevant for supporting end-of-life care planning. Conclusions: Participant feedback indicated that the DESIRE intervention can be integrated into practice to support patients, relatives, and health professionals in planning end-of-life care alongside the management of worsening kidney failure. Minimising exhaustion and enhancing engagement with the intervention should be a focus for subsequent refinement of the intervention. Registration: The study has been registered at ClinicalTrials.gov with the identifier: NCT05842772. Date of first recruitment: March 20, 2023.
