Objective: To identify determinants of medication non-adherence in a Swedish population of systemic lupus erythematosus (SLE).
Methods: Patients with SLE from Karolinska and Örebro University Hospitals participated in a survey-based cross-sectional study. Demographics, disease activity, organ damage, HRQoL (LupusQol, EQ-5D-5 L), medication non-adherence (<80% on CQR-19 or MASRI) and beliefs about medicines (BMQ) were registered. MASRI was used to report adherence to different drugs/drug classes, categorised into (i) antimalarial agents (AMA), (ii) glucocorticoids and (iii) other SLE medications. Multivariable logistic regression adjusted for age, sex, disease activity and organ damage.
Results: Among 205 respondents, the median age was 52.0 years (IQR: 34.0-70.0), 86.3% were women, 66.8% were non-adherent to their medications according to CQR-19, and 6.6% and 6.3% were non-adherent to AMA and glucocorticoids, respectively, according to MASRI. Positive beliefs about glucocorticoids (OR; 95% CI: 0.77; 0.59-0.99; = .039) and medications overall (0.71; 0.52-0.97; = .029) were protective against non-adherence to glucocorticoids. Anxiety/depression (3.09; 1.12-8.54; = .029), medication concerns (1.12; 1.05-1.20; < .001) and belief that medications are overused (1.30; 1.15-1.46; < .001) or harmful (1.36; 1.19-1.56; < .001) were associated with medication non-adherence (CQR-19); beliefs in the necessity of medications (0.73; 0.65-0.82; < .001) and positive beliefs in medications were protective (0.72; 0.60-0.86; < .001). No associations were found between other investigated factors and medication non-adherence.
Conclusions: Beliefs about medications were a major determinant of medication non-adherence. Patient education may help alleviate the negative impact of misinformation/unawareness on adherence.
