AimTo describe the development of a shared decision making intervention for planning end‐of‐life care for patients with kidney failure, their relatives and health professionals in kidney services.BackgroundEnd‐of‐life care conversations within standard disease management consultations are challenging for patients with kidney failure, their relatives and health professionals. End‐of‐life care planning is about making difficult decisions in advance, which is why health professionals need shared decision making skills to be able to initiate end‐of‐life conversations. Health professionals report needing more skills to raise the issue of end‐of‐life care options within consultations and patients want to be able to discuss issues important to them about future care plans.MethodsThe development design was guided by the UK Medical Research Council's framework and a user‐centred approach was applied. Four workshops were conducted with end users. The Template for Intervention Description and Replication for Population Health and Policy interventions was used to shape which questions needed to be answered through the workshops and to present the intervention. The International Patient Decision Aid Standards (IPDAS) criteria set the standards to be achieved.ResultsAreas considered significant to a shared decision making intervention were training of health professionals, conversations about end‐of‐life care, planning and evaluation of the decisions, reporting decisions in health records and repetition of consultation. The development process went through 14 iterations.ConclusionAn intervention named DESIRE was developed that comprises: (1) a training programme for health professionals; (2) shared decision making conversations; and (3) a patient decision aid. The intervention met 30 out of 33 IPDAS criteria.Implications for practiceDESIRE is intended to support shared decision making about planning end‐of‐life care among patients with kidney failure, their relatives and health professionals. The study provides important tools for the stakeholders engaged that can be used within different models of care.ImpactWhat problem did the study address?International guidelines recommend health professionals involve patients with kidney failure in making decisions about end‐of‐life care, but there is variation in how this is implemented within and across kidney services. Furthermore, patients, relatives and health professionals find it challenging to initiate conversations about end‐of‐life care.What were the main findings?The study resulted in the development of a complex intervention, called DESIRE, about shared decision making and planning end‐of‐life care for patients with kidney failure, their relatives and health professionals in kidney services, including a training programme for health professionals, shared decision making conversations and a patient decision aid.Where and on whom will the research have an impact?The research contributes a shared decision making intervention to patients in the later stage of kidney failure, their relatives and health professionals. We believe that the DESIRE intervention could be introduced during consultations with health professionals at an earlier stage of the patient's illness trajectory, as well as being applied to other chronic diseases.Reporting MethodThis intervention development research is reported according to the GUIDance for the rEporting of intervention Development (GUIDED) checklist and the DEVELOPTOOLS Reporting Checklist.Patient or Public ContributionPatients, relatives and health professionals have been involved throughout the research process as part of the research team and advisory board. For this study, the advisory board has particularly contributed to the development process of the DESIRE intervention by actively participating in the four workshops, in the iterations between the workshops and in the preparation of the manuscript.
