Abstract Aims International studies have examined patients’ views concerning the discussion of deactivating an implantable cardioverter defibrillator (ICD). Findings reported that many patients were either not informed about the subject or were informed late in their illness trajectory. This study aimed to explore healthcare professionals’ perspectives on discussing ICD deactivation and identify priorities for clinical practice and future research. Methods and results Eleven interviews were conducted, involving heart failure nurses, physicians, and an allied professional. All were responsible for the care of patients with an ICD, from the UK or Sweden. A semi-structured guide was used. All interviews were audio-recorded, transcribed, translated (as applicable), and analysed independently by experienced researchers, using framework analysis. Findings were presented, along with published work at a stakeholder meeting, and a consensus agreement was reached on priorities for clinical practice and future research. Four themes emerged from the exploratory interviews. Healthcare professionals described the discussion about deactivation as challenging, requiring compassion and involvement of family members. They agreed that the topic should be initiated prior to, or shortly after, device implantation. This was reflected in the priorities to improve communication, through the increased availability and implementation of prompts and tools, as well as the provision of tailored information to patients and family members. Stakeholders recognized the future potential of digital technology in device education. Conclusion Discussing deactivation remains challenging. Healthcare professionals recognized the need to initiate the discussion early, with compassion and involvement of family members. Priorities were agreed by stakeholders, which require clinical implementation and further research.
