Videos to reduce racial disparities in ICD therapy Via Innovative Designs (VIVID) trial: Rational, design and methodology

Background Despite a higher prevalence of sudden cardiac death (SCD), black individuals are less likely than whites to have an implantable cardioverter defibrillator (ICD) implanted. Racial differences in ICD utilization is in part explained by higher refusal rates in black individuals. Decision support can assist with treatment-related uncertainty and prepare patients to make well-informed decisions. Methods The Videos to reduce racial disparities in ICD therapy Via Innovative Designs (VIVID) study will randomize 350 black individuals with a primary prevention indication for an ICD to a racially concordant/discordant video-based decision support tool or usual care. The composite primary outcome is (1) the decision for ICD placement in the combined video groups compared with usual care and (2) the decision for ICD placement in the racially concordant relative to discordant video group. Additional outcomes include knowledge of ICD therapy and SCD risk; decisional conflict; ICD receipt at 90 days; and a qualitative assessment of ICD decision making in acceptors, decliners, and those undecided. Conclusions In addition to assessing the efficacy of decision support on ICD acceptance among black individuals, VIVID will provide insight into the role of racial concordance in medical decision making. Given the similarities in the root causes of racial/ethnic disparities in care across health disciplines, our approach and findings may be generalizable to decision making in other health care settings.
