Patient-Reported Factors in Treatment Satisfaction in Patients with Relapsed/Refractory Multiple Myeloma (RRMM)

Therapy choices in relapsed/refractory multiple myeloma (RRMM) should consider patient satisfaction with treatment, because it is associated with adherence to therapy, health outcomes, and medical safety. The primary objective of this pilot cross-sectional observational study was to ascertain factors associated with patient-reported treatment satisfaction in RRMM.

Patients with a self-reported diagnosis of RRMM recruited from PatientsLikeMe, MyelomaCrowd, and Facebook were administered an electronic survey that included questions on demographics and clinical history, treatment experience, economic burden, and standardized patient-reported outcome measures, including the Treatment Satisfaction Questionnaire for Medication, Eastern Cooperative Oncology Group performance status (ECOG PS) measure, and Work Productivity and Activity Impairment Questionnaire: Specific Health Problem V2.0. Univariable and multivariable analyses were used to identify predictors of patient-perceived treatment satisfaction.

One hundred sixty patients with RRMM participated in the study, with a median of two prior relapses and 66.3% reporting the most recent relapse within the last 12 months. ECOG PS ≥2 was associated with lower patient-reported global satisfaction and perceived effectiveness of current treatment. In addition to shorter time spent receiving therapy, orally administered treatment was the strongest predictor of higher satisfaction with treatment convenience. For patients receiving an injectable drug-containing regimen versus an all-oral regimen, respectively, time spent receiving multiple myeloma-directed therapy was higher (12.6 vs. 4.0 hours per month), and total monthly indirect costs were $1,033 and $241.

Poor ECOG PS was linked to reduced treatment satisfaction and perceived effectiveness of current therapy, whereas an all-oral regimen was associated with increased treatment convenience satisfaction.

This study suggests that attributes including better Eastern Cooperative Oncology Group performance status, less time spent receiving treatment, and oral route of treatment administration lead to higher patient-perceived satisfaction with relapsed/refractory multiple myeloma (RRMM) treatment. Oral route of administration was also associated with less time spent receiving treatment and reduced economic burden for patients. Increased attention to these factors in shared treatment decision making is warranted to help identify individual patient needs, preferences, and expectations for RRMM treatments, to resolve dissatisfaction issues, and to improve the experience of patients with RRMM.
