Knowledge of epilepsy surgery: A survey among medical doctors in Nigeria

Background: Epilepsy surgery has been shown to significantly improve the quality of life of patients with drug resistant epilepsy. Despite this, epilepsy surgery remains remarkably underutilized in Nigeria. There are high misconceptions about epilepsy and its management among physicians and trainees. Methods: This study aims to identify knowledge gaps in epilepsy surgery among medical doctors in Nigeria and factors associated with their level of knowledge of the procedure. A cross-sectional study was carried out among 566 medical doctors in Nigeria, at different levels of post-graduate training (House officers, Medical officers, Resident doctors and Consultants). An online survey with a 24-item questionnaire adapted from a standardized pro forma was utilized. Binary and multiple logistic regression were used to identify associations between the independent variable and outcome variable (good or poor knowledge) Results: Majority of the respondents were medical officers (post-intern physicians) comprising 65.7 % of the participants. Significant predictors of poor knowledge included being a medical officer [P=0.006], working in north-central [P=0.017] and north-western Nigeria [P=0.045], seeing less than 20 epilepsy patients per month [1-10 patients, P=0.015; 11-20 patients, P=0.011], and enrolment in online epilepsy course [P=0.004]. Conclusion: Comprehensive education and awareness about epilepsy surgery are important in overcoming the knowledge gap and improving access to care.
