Magnitude of uncontrolled seizures and associated factors among people with epilepsy. Data from a major teaching hospital in Southwest Ethiopia.

BACKGROUND

Epilepsy is a major public health problem affecting 70 million people worldwide. 90% of global people with epilepsy were living in developing regions like Ethiopia. Due to the lack of clear guidelines for treatment selection and the difficulty of individualizing care in resource-poor settings, achieving seizure control can be challenging. Seizure control status among epileptic patients is affected by different factors. Accordingly, this study aimed to assess the magnitude of uncontrolled seizures and associated factors among people with epilepsy attending the outpatient clinic of Jimma Medical Center, Southwest Ethiopia.

METHODS

A hospital-based retrospective chart review and a respective patient interview conducted among people with epilepsy from October 2020 to June 2021. Sociodemographic, behavioral-related factors, medication adherence, and medication belief were obtained through patient interviews. Seizure control status in the last two years before the study period was retrospectively evaluated and recorded from the charts. Data were entered into Epi Data manager version 4.6 and then exported to SPSS version 23.0 for analysis. A backward logistic regression analysis was done to identify factors associated with uncontrolled seizures.

RESULTS

From a total of 314 medical charts reviewed, 149(47.5 %) of patients were with uncontrolled seizures. 28.7 %,12.8 %, and 6 % of the patients experienced 1-5,6-10, and >10 seizure episodes during the last two years respectively. Comorbidity [adjusted odds ratio [(AOR): 2.13, 95 % confidence interval (CI):1.26-3.58], nonadherence [AOR: 2.41, 95 %CI: 1.46-3.9], possible adverse drug reaction (ADR) [AOR:1.79, 95 %CI: 1.107-3.01], and drug interaction [AOR: 3.06, 95 %CI: 1.24-7.57] were associated with an uncontrolled seizure.

CONCLUSION AND RECOMMENDATION

Our study showed that a substantial proportion of the patients were with uncontrolled seizures. Epileptic patients with comorbidities, nonadherence, adverse drug reactions, and drug interactions were more prone to have uncontrolled seizures. Hence, to overcome these problems, strategies like community-based education, treatment intensification, and routine assessment of adverse drug reactions and drug interaction may help to improve seizure control status.
