Abstract

Background Despite widespread use, there are few studies evaluating the consumer Choosing Wisely questions. Methods We evaluated the impact of the Choosing Wisely questions on consumers’ decision-making outcomes. Adults living in Australia were presented with a hypothetical low-value care scenario. Using a 2×2×2 between-subjects factorial design, they were randomized to either the Choosing Wisely questions (“Questions†), a shared decision-making (SDM) preparation video (“Video†), both interventions, or control (no intervention). Primary outcomes were 1) self-efficacy to ask questions and be involved in decision-making and 2) intention to engage in SDM. Results A total of 1,439 participants (45.6% with “inadequate†health literacy) were eligible and included in the analysis. Intention to engage in SDM was higher in people randomized to the Video (mean difference [MD] = 0.24 [scale 0–6], 95% confidence interval [CI]: 0.14, 0.35), Questions (MD = 0.12, 95% CI: 0.01, 0.22), and both interventions (MD = 0.33, 95% CI: 0.23–0.44, P   80%), but proactive access was low (1.7%–20.8%). Compared with control, participants who received one or both interventions asked more questions that mapped to the Choosing Wisely questions (all P
