High adherence of patients with multiple myeloma who receive treatment with immunomodulatory drugs (IMIDS) in hematology/oncology group practices in Germany

Immunomodulatory drugs (IMIDS) have changed the treatment and outcome of patients suffering from multiple myeloma. However, with the oral administration adherence becomes an issue. Since there is no “gold standard” in measuring adherence, we assessed the adherence of myeloma patients with the help of different data sources.
All patients who have been receiving IMIDS for at least 3 months were eligible. Computer assisted personal interviews of patients and, if possible, their caregivers were carried out. Attending oncologists evaluated the patient’s adherence with the help of a standardized questionnaire. In addition, a retrospective analysis of prescription data was conducted. All data were analyzed statistically using SPSS.
One hundred myeloma patients, 35% female, 65% male, with a median age of 70 years (37–86) were interviewed. Prescription data could be evaluated in terms of adherence in 78 patients (78%), 56 caregivers could be questioned (56%). Ninety-seven percent of patients rated themselves as adherent in taking IMIDS. Data from treating oncologists, caregivers and prescriptions supported this result. IMID therapies were rated as very effective and significant, toxicities were acceptable and dosing regimens simple/uncomplicated.
Myeloma patients seem to be highly adherent to IMID treatments.
