Poor medication adherence is a critical challenge for clinicians in managing epilepsy patients. This study assessed the relationship between demographic, clinical, and neuropsychological factors and medication adherence in a population of 200 epilepsy patients. The results showed that female gender and older age were associated with better medication adherence. These findings could contribute to the development of decisional support systems in outpatient epilepsy clinics.
Objectives: Poor medication adherence in people with epilepsy (PwE) increases mortality, hospitalization, and poor quality of life, representing a critical challenge for clinicians. Several demographic, clinical, and neuropsychological factors were singularly found associated with medication adherence in several stud-ies, but the literature lacks a comprehensive study simultaneously assessing all these variables. Methods: We performed a multicenter and cross-sectional study using online questionnaires with the following clinical scales: Morisky Medication Adherence Scale (MMAS-8), Quality of Life in Epilepsy Inventory 31 (QoLIE-31), Beck Depression Inventory-II (BDI-II), Generalized Anxiety Disorder-7 (GAD-7) and 14-item Resilience scale (RES14) in a population of 200 PwE. We used the ANOVA test and Spearman's correlation to evaluate the relationship between medication adherence and demographic, clinical (seizure frequency, number of anti-seizure medications), and neuropsychological characteristics. We trained separate machine learning models (logistic regression, random forest, support vector machine) to classify patients with medium-high adherence (MMAS-8 >= 6) and poor adherence (MMAS-8 < 6) and to identify the main features that influence adherence. Results: Women were more adherent to medication (p-value = 0.035). Morisky Medication Adherence Scale-8 showed a direct correlation with RES14 (p-value = 0.001) and age (p-value = 0.001), while was inversely correlated with BDI-II (p-value = 0.001) and GAD-7 (p-value = 0.001). In our model, the variables mostly predicting treatment adherence were QoLIE-31 subitems, followed by age, resilience, anxiety, years of school, and disease duration. Conclusion: Our study confirms that gender, age, and neuropsychological traits are relevant factors in predicting medication adherence to PwE. Furthermore, our data provided the first evidence that machine learning on multidimensional self-report questionnaires could help to develop a decisional support sys-tem in outpatient epilepsy clinics.
