Patient Confidence and Information Preferences During the Treatment Decision-making Process: Results From a Large Multiple Myeloma Patient Survey Across 12 Countries in Europe and Israel.

Background: The relapsing nature of multiple myeloma (MM) means that patients typically receive different and multiple lines of therapy, requiring many treatment decisions over the disease course. The aim of this study was to explore patient confidence and information preferences during the treatment decision-making process.

Patients And Methods: A multinational, cross-sectional survey enrolled patients with MM. It was co-developed and distributed by Myeloma Patients Europe across 12 countries in Europe and Israel from May 2019 to March 2020. Eligibility criteria included a self-reported diagnosis of MM and being able to recall the decision-making process at the start of their latest treatment line.

Results: A total of 1559 patients were included, with complete responses received from 1081 (69%) patients. The median age range was 54 to 64 years; there was an equal gender split and 57% had their latest treatment decision made within the past year. Overall, 54% of patients felt "very confident" in the latest treatment decision. Patients deemed the most important information to be safety/tolerability and treatment effectiveness, but the latter was among the least frequently received. Most patients reported that their primary physician treating MM was their main source for all types of information (range, 62%-94%), with 87% of patients reporting a "very good" or "good" relationship with them.

Conclusion: Over half of patients felt very confident in their latest treatment decision; however, patients reported not routinely receiving important treatment effectiveness information. Addressing the discrepancies between information that patients receive and consider important may enhance confidence in decision-making.
