Adherence to anti-seizure medications and self-reported availability and affordability of the medications in Addis Ababa, Ethiopia.

BACKGROUND

Anti-seizure medications (ASMs) are the primary therapeutic mode to control seizures in patients with epilepsy. Adherence to the medications is critical to achieving the goals of epilepsy therapy. However, the cost of the medications and the interrupted availability of ASMs contribute to non-adherence to epilepsy treatment. Therefore, this study aimed to assess ASM adherence and its association with self-reported medication availability and affordability.

OBJECTIVE

To assess whether self-reported availability and affordability of Anti-seizure medications affect medication adherence among Epileptic Patients at Eka Kotebe General Hospital, Addis Ababa, Ethiopia, from January 13, 2023 to March 23, 2023.

METHODS

A hospital-based analytical cross-sectional study was conducted among 357 epileptic patients using the Consecutive sampling method in Eka Kotebe General Hospital, Addis Ababa, Ethiopia. ASM adherence was measured using a self-report 3items questionnaire focusing on medication use patterns of patients from their last visit to the current visit. Statistical packages for Social Sciences 26.0 version statistical software cleaned, coded and analyzed the collected data. Binary logistic regression was fitted, and P-values less than 0.05 were considered to have statistical significance.

RESULT

The prevalence of ASM adherence was 55.2% with 95% CI (50.1%; 60.2%). About two-thirds (61.3%) of patients in this study had limited access to the ASMs or could not afford the medications. Self-reported availability of ASMs (AOR = 2.01, 95% CI = 1.01, 3.98) was significantly associated with ASM adherence. Self-reported affordability of ASMs was associated with ASM adherence in the Bivariate logistic regression analysis; however, when adjusted for other covariates in the multivariable logistic regression, no significant association was observed (p = 0.674).

CONCLUSION AND RECOMMENDATION

Only about half of the epileptic patients adhered to ASMs at Eka Kotebe General Hospital. Self-reported availability of ASMs was an essential factor. Improving access to ASMs is critical to improving adherence and management of epilepsy.
