Pattern of anti-epileptic medications nonadherence and associated factors at ambulatory clinic of Jimma Medical Center, Southwestern Ethiopia: A prospective observational study.

Objective:This study is designed to assess the pattern of nonadherence, and associated factors among ambulatory patients with epilepsy at Jimma Medical Center, Southwestern Ethiopia, from November 2020 to April 2021. Methods:A hospital-based prospective observational study was employed. A consecutive sampling method was used to recruit study participants. Nonadherence was assessed by the Hill-Bone compliance to the high blood pressure therapy scale. A threshold of 18 scores was used to classify adherence status. Epi-Data manager version 4.6 was used for data entry and all statistical analysis was performed by Statistical Package for Social Science 25.0. Multivariable logistic regression was performed to explore associated factors. Results:A survey included 334 patients with epilepsy. One hundred twenty-two (36.52%) of the study participants were found to be non-adherent. The factors associated with nonadherence were poor involvement of the patient in the therapeutic decision (adjusted odds ratio = 1.74; 95% confidence interval: 1.04-2.90; p = 0.034), per month income of lesser than1000 Ethiopian birr (adjusted odds ratio = 2.66; 95% confidence interval: 1.03-6.84; p = 0.042), recent seizure episodes (adjusted odds ratio = 1.97; 95% confidence interval: 1.20-3.23; p = 0.007), adverse drug reaction (AOR = 2.13; 95% confidence interval: 1.31-3.47; p = 0.002), and negative medication belief (adjusted odds ratio = 1.28; 95% confidence interval: 1.53-2.25; p = 0.043). Conclusions:In our setting, the magnitude of nonadherence was substantially high. Hence, providing regular health-related information about the disease and treatment, supplying free antiepileptic drugs, routine assessment of adverse drug reactions, and a multidisciplinary approach involving patients may improve adherence.
