Text-only and picture conversation aids both supported shared decision making for breast cancer surgery: Analysis from a cluster randomized trial.

To determine if two encounter conversation aids for early-stage breast cancer surgery increased observed and patient-reported shared decision making (SDM) compared with usual care and if observed and patient-reported SDM were associated. Surgeons in a cluster randomized trial at four cancer centers were randomized to use an Option Grid, Picture Option Grid, or usual care. We used bivariate statistics, linear regression, and multilevel models to evaluate the influence of trial arm, patient socioeconomic status and health literacy on observed SDM (via OPTION-5) and patient-reported SDM (via collaboRATE). From 311 recordings, OPTION-5 scores were 73/100 for Option Grid (n = 40), 56.3/100 for Picture Option Grid (n = 144), and 41.0/100 for usual care (n = 127; p < 0.0001). Top collaboRATE scores were 81.6 % for Option Grid, 80.0 % for Picture Option Grid, and 56.4 % for usual care (p < 0.001). Top collaboRATE scores correlated with an 8.60 point (95 %CI 0.66, 13.7) higher OPTION-5 score (p = 0.008) with no correlation in the multilevel analysis. Patients of lower socioeconomic status had lower OPTION-5 scores before accounting for clustering. Both conversation aids led to meaningfully higher observed and patient-reported SDM. Observed and patient-reported SDM were not strongly correlated. Healthcare providers could implement these conversation aids in real-world settings.
