MONDAY, April 3, 2023 (HealthDay News) — A video-based decision support tool increases knowledge for Black patients eligible for an implantable cardioverter-defibrillator (ICD), but does not increase assent to ICD implantation, according to a study published online April 4 in the Annals of Internal Medicine.
Kevin L. Thomas, M.D., from the Duke University School of Medicine in Durham, North Carolina, and colleagues examined the effectiveness of a video decision support tool for Black patients eligible for an ICD in a randomized clinical trial. A total of 330 patients were randomly assigned to an encounter-based video decision support tool or usual care; 311 contributed data for the primary outcome: the decision regarding ICD implantation.
The researchers found that assent to ICD implantation was 58.6 and 59.4 percent in the video group and usual care group, respectively. Participants in the video group had a higher mean knowledge score compared with the usual care group (difference, 0.7) and a similar decisional conflict score. The rate of ICD implantation was 67.5 percent within 90 days, with no differences noted by intervention. Compared with those in the usual care group, patients in the video group spent less time with their clinician (mean, 22.1 versus 27.0 minutes).

“Among Black patients who were eligible for an ICD, use of an encounter-based video decision support tool increased patient knowledge but did not affect assent to ICD implantation or actual ICD implantation compared with usual care,” the authors write.
