Impact of Cost Conversation on Decision-Making Outcomes

To understand the impact of cost conversations on the following decision-making outcomes: patients' knowledge about their conditions and treatment options, decisional conflict, and patient involvement.

In 2020 we performed a secondary analysis of a randomly selected set of 220 video recordings of clinical encounters from trials run between 2007 and 2015. Videos were obtained from eight practice-based randomized trials and one pre-post-prospective study comparing care with and without shared decision-making (SDM) tools.

The majority of trial participants were female (61%) and White (86%), with a mean age of 56, some college education (68%), and an income greater than or equal to $40,000 per year (75%), and who did not participate in an encounter aided by an SDM tool (52%). Cost conversations occurred in 106 encounters (48%). In encounters with SDM tools, having a cost conversation lead to lower uncertainty scores (2.1 vs 2.6, P=.02), and higher knowledge (0.7 vs 0.6, P=.04) and patient involvement scores (20 vs 15.7, P=.009) than in encounters using SDM tools where cost conversations did not occur. In a multivariate model, we found slightly worse decisional conflict scores when patients started cost conversations as opposed to when the clinicians started cost conversations. Furthermore, we found higher levels of knowledge when conversations included indirect versus direct cost issues.

Cost conversations have a minimal but favorable impact on decision-making outcomes in clinical encounters, particularly when they occurred in encounters aided by an SDM tool that raises cost as an issue.
