A video decision support tool for Black patients with heart failure increased patient knowledge but did not increase the rate of implantable cardioverterdefibrillator (ICD) implantation.
Background: Racial disparities in implantable cardioverterdefibrillator (ICD) implantation are multifactorial and are partly explained by higher refusal rates. Objective: To assess the effectiveness of a video decision support tool for Black patients eligible for an ICD. Design: Multicenter, randomized clinical trial conducted between September 2016 and April 2020. (ClinicalTrials.gov: NCT02819973) Setting: Fourteen academic and community-based electrophysiology clinics in the United States. Participants: Black adults with heart failure who were eligible for a primary prevention ICD. Intervention: An encounter-based video decision support tool or usual care. Measurements: The primary outcome was the decision regarding ICD implantation. Additional outcomes included patient knowledge, decisional conflict, ICD implantation within 90 days, the effect of racial concordance on outcomes, and the time patients spent with clinicians. Results: Of the 330 randomly assigned patients, 311 contributed data for the primary outcome. Among those randomly assigned to the video group, assent to ICD implantation was 58.6% compared with 59.4% in the usual care group (difference, -0.8 percentage point [95% CI, -13.2 to 11.1 percentage points]). Compared with usual care, participants in the video group had a higher mean knowledge score (difference, 0.7 [CI, 0.2 to 1.1]) and a similar decisional conflict score (difference, -2.6 [CI, -5.7 to 0.4]). The ICD implantation rate within 90 days was 65.7%, with no differences by intervention. Participants randomly assigned to the video group spent less time with their clinician than those in the usual care group (mean, 22.1 vs. 27.0 minutes; difference, -4.9 minutes [CI, -9.4 to -0.3 minutes]). Racial concordance between video and study participants did not affect study outcomes. Limitation: The Centers for Medicare & Medicaid Services implemented a requirement for shared decision making for ICD implantation during the study. Conclusion: A video-based decision support tool increased patient knowledge but did not increase assent to ICD implantation.
