High medication prices can create a financial burden for patients and reduce medication initiation. To improve decision making, public policy is supporting development of tools to provide real-time prescription drug prices. We reviewed the literature on medication cost conversations to characterize the context in which these tools may be used. Our review included 42 articles: a median of 84% of patients across four clinical specialties reported a desire for cost conversations (n = 7 articles) but only 23% reported having held a cost conversation across six specialties (n = 16 articles). Non-White and older patients were less likely to report having held a cost conversation than White and younger patients in 9 of 13 and 5 of 9 articles, respectively, examining these associations. Our review indicates that tools providing price information may not result in improved decision making without complementary interventions that increase the frequency of cost conversations with a focus on protected groups.
