Background: Pain is a significant problem in patients with cancer. Breakthrough cancer pain contributes to the pain experience, but it is often underassessed and underrecognized. Shared decision-making (SDM), where patient preferences, goals, and concerns are discussed and integrated into a shared decision, can potentially foster earlier identification of pain, including breakthrough cancer pain, and improve pain management. Objectives: To explore the use of SDM to evaluate its impact on cancer pain management. Methods: This prospective, multisite study engaged patients with advanced cancer to explore the use of SDM in managing cancer pain using a digital platform with an expanded pain assessment. Decision preferences were noted and incorporated into care. Outcomes included pain and patient-perceived pain care quality. Results: 51 patients with advanced cancer enrolled in the study. The mean pain score was 5 out of 10 throughout the three study time points. 88% of patients experienced breakthrough cancer pain of severe intensity at baseline and approximately 70% at visits two and three. The majority of breakthrough cancer pain episodes lasted longer than 30 minutes. The majority (86%) of participating patients desired shared decision-making or patient-driven decision-making. Most patients expressed satisfaction with the level of shared decisionmaking in managing their cancer pain. Breakthrough cancer pain remained significant for most patients. Conclusions: SDM incorporated into pain discussions has the potential to improve pain outcomes, but significant challenges remain in managing breakthrough cancer pain.
