Antiepileptic Drug Treatment Outcomes and Seizure-Related Injuries Among Adult Patients with Epilepsy in a Tertiary Care Hospital in Ethiopia

The impact of COVID-19 on treatment follow-up and medication adherence among patients with epilepsy at a referral hospital in Ethiopia

BACKGROUND

The world continues to be challenged by the Coronavirus disease 2019 (COVID-19) and preventive measures like maintaining social distancing and lockdowns challenge patients to attend regular follow-ups and get a refill for medication that causes adherence problems. Hence, this study attempts to assess the impact of COVID-19 on treatment follow-up and medication adherence among patients with epilepsy.

METHOD

A total of 276 patients with epilepsy were enrolled in the study. Data collection was carried out through medical record reviews and patient interviews. Patients who visited Zewditu Memorial Hospital from August to September 2021 and those who had follow-up at least for two years before the outbreak of the pandemic were included. The data was analyzed using SPSS v.24.

RESULT

About 69.6% of patients were adherent to their treatment and 83.3% of the patients had a seizure-free period of less than 1 year. Ninety (32.6%) of the participants missed their treatment follow-up during the pandemic, mainly due to fear of being infected with COVID-19. Sixty-eight (24.6%) patients have experienced increased seizure episodes during the pandemic as compared to the previous times. Moreover, 56 (20.3%) participants were not taking their antiseizure medications (ASMs) during the pandemic because of the unavailability of medications and they discontinued hospital visits for their medication refills. Among those who missed their treatment follow-up, 20% had seizure-related physical injuries. Only educational level has a significant association with visiting health facilities during the pandemic. Thus, participants who completed college and above (OR = 2.58, 95% CI (1.32-6.38)) were more likely to attend their follow-up during the pandemics as compared to participants who can't read and write.

CONCLUSION

The present study revealed that COVID-19 might have impacts on treatment follow-up and medication adherence due to fear of infection, travel restrictions and the indirect impact on the availability and affordability of medications. These might lead to poor treatment outcomes like increased seizure frequency and seizure-related physical injuries.

Epilepsy Treatment Outcome and Its Predictors Among Children Who Had Chronic Follow Up at Dessie Comprehensive Specialized Hospital

Introduction

Epilepsy is a chronic non-communicable disease of the brain that affects millions of people worldwide. A significant number of children are affected globally, and most live in developing countries, often with physical and cognitive disabilities. Regardless of these factors, epilepsy is poorly controlled, particularly in the developing countries. Thus, this study aimed to assess the magnitude of treatment outcomes and its predictors among pediatrics patients with epilepsy who were followed-up at the Dessie Comprehensive Specialized Hospital, Northeast Ethiopia.

Methods

Hospital-based cross-sectional study was conducted from 1 June 2022 to 30 August 2022. A total of 200 patients with epilepsy were included in this study. Data were collected through face-to-face interviews, and by reviewing medical records. The collected data were entered into Epi-data version 4.6 and exported to SPSS version 25.0. Descriptive statistics such as frequencies, percentages, means and standard deviations were computed. Binary and multivariate logistic regression analyses were performed. Variables with p < 0.25 in bivariate analysis were entered into multivariable logistic regression. In multivariable analysis, adjusted odd ratio with 95% CI and p-value less than 0.05 were considered statistically significant.

Results

Of 200 pediatric patients with epilepsy, 66 (34.5%) had poor treatment outcomes. In the multivariate analysis, 11-15 years of age (AOR = 4.08; 95% CI = 1.202, 13.848), poor treatment adherence (AOR = 3.21; 95% CI = 1.421, 7.249), history of more seizure frequency before starting treatment (AOR = 4.19; 95% CI = 1.984, 8.834) and history of head injury (AOR = 3.03; 95% CI = 1.502, 6.112) were significantly associated with poor treatment outcomes in pediatric patients with epilepsy.

Conclusion

Significant proportion of pediatric patients with epilepsy had poor treatment outcomes. Therefore, health-care workers should strictly follow patient treatment especially for pediatric epileptic patients' who have poor treatment adherence, more seizure frequency history, head injury history and whose age were 11-15 years old.

Seizure Remission and Its Predictors Among Epileptic Patients on Follow-Up at Public Hospitals in Eastern Ethiopia: A Retrospective Cohort Study

Background

Epilepsy is one of the common chronic neurological disorders with varying therapeutic responses. Despite the high prevalence of epilepsy and the significant treatment gaps in developing nations, such as Ethiopia, there is a dearth of data on seizure remission and its predictors in Eastern Ethiopia in particular.

Objective

This study aimed to determine seizure remission and its predictors among epileptic patients on follow-up in Hiwot Fana Specialized University Hospital (HFSUH) and Dilchora Referral Hospital (DCRH), from July 2 to 31, 2021.

Methods

A retrospective cohort study was conducted among 418 newly diagnosed epilepsy patients receiving anti-seizure drugs (ASDs) between July 1, 2014, and July 31, 2019, in two public hospitals in Eastern Ethiopia. Relevant data were collected for all patients with a minimum follow-up period of two years. Data were analyzed using SPSS Version 21. Cox proportional hazards model was performed to identify predictors of seizure remission.

Results

Overall, 252 (60.3%) of the study participants have achieved seizure remission for at least one year. The mean time to achieve seizure remission was 1.9 ± 0.87 years. Regarding the seizure remission pattern, 171 (40.9%) patients achieved early remission, 81 (19.4%) achieved late remission, and 166 (39.7%) achieved no remission. Shorter pre-treatment duration (AHR = 2.36, 95% CI: 1.28-4.37); good adherence to ASDs (AHR = 2.40, 95% CI: 1.33-4.34); and monotherapy (AHR = 0.56, 95% CI: 0.32-0.98) were predictors of seizure remission.

Conclusion

We observed that less than two-thirds of epileptic patients had achieved seizure remission. A shorter pre-treatment duration, good adherence to ASDs, and monotherapy were predictors of seizure remission. Therefore, we recommend the requirement of an integrated effort from different health disciplines that increases patients' adherence to ASDs, promotes early visits to medical facilities, and improves the health-seeking behavior of epileptic patients.

Clinical Characteristics, Treatment Outcome and Associated Factors of Epilepsy Among Children at Hospitals of North-West Ethiopia

Background

Epilepsy is an important cause of neurological morbidity in children and adolescents. Clinical parameters are the main diagnostic tools, especially in developing countries. Although cost-effective treatments for epilepsy are available, studies have shown that uncontrolled seizures can occur in many patients.

Objective

To assess clinical characteristics, treatment outcomes, and associated factors for controlled epilepsy among children with epilepsy who underwent follow-up at the Debre Markos Comprehensive Specialized Hospital, North-west Ethiopia from October 28, 2020, to April 28, 2021.

Methods

An institutional-based retrospective cohort study was conducted from October 28, 2020, to April 28, 2021. A total of 385 participants who fulfilled the inclusion criteria were included in the study. A pretested, structured, interviewer-administered questionnaire with a chart review was used to collect data. The data were entered into the Epi-data software version 4.4.2.1 and then exported to the Stata version 14 statistical package for analysis. Descriptive statistics were used to describe the sociodemographic and clinical characteristics, treatment profiles, and treatment outcomes of patients with epilepsy. Bivariate and multivariate analyses were used to identify factors associated with treatment outcomes.

Results

The most frequent type of seizure among the 385 respondents was Generalized-tonic-clonic seizures (88.1%). The proximate cause of seizures was identified in 15% of patients, of whom 45 had a perinatal history (8.8%), head injury (3.6%), and CNS infection (2.3%). One-third of patients had poor seizure control. Caregiver relationship (father AOR=0.58; 95th CI:0.35,0.97) and poor adherence (AOR=2.97; 95th CI:1.82, 4.86) were significantly associated with treatment outcome.

Conclusion

One-third of children with epilepsy have poor seizure control. Poor adherence to treatment is implicated in poor control. Counseling caregivers on proper treatment and adherence to anti-epileptic medication is recommended to improve treatment outcome in children.

Recent Progress in the Development of New Antiepileptic Drugs with Novel Targets

Background

Epilepsy is a chronic neurological disorder that affects approximately 50-70 million people worldwide. Epilepsy has a significant economic and social burden on patients as well as on the country. The recurrent, spontaneous seizure activity caused by abnormal neuronal firing in the brain is a hallmark of epilepsy. The current antiepileptic drugs provide symptomatic relief by restoring the balance of excitatory and inhibitory neurotransmitters. Besides, about 30% of epileptic patients do not achieve seizure control. The prevalence of adverse drug reactions, including aggression, agitation, irritability, and associated comorbidities, is also prevalent. Therefore, researchers should focus on developing more effective, safe, and disease-modifying agents based on new molecular targets and signaling cascades.

Summary

This review overviews several clinical trials that help identify promising new targets like lactate dehydrogenase inhibitors, c-jun n-terminal kinases, high mobility group box-1 antibodies, astrocyte reactivity inhibitors, cholesterol 24-hydroxylase inhibitors, glycogen synthase kinase-3 beta inhibitors, and glycolytic inhibitors to develop a new antiepileptic drug.

Key messages

Approximately 30% of epileptic patients do not achieve seizure control. The current anti-seizure drugs are not disease modifying, cure or prevent epilepsy. Lactate dehydrogenase inhibitor, cholesterol 24-hydroxylase inhibitor, glycogen synthase kinase-3 beta inhibitors, and mTOR inhibitors have a promising antiepileptogenic effect.

Assessment of Treatment Outcome and Its Associated Factors among Adult Epileptic Patients in Public Hospitals in the Southern Ethiopia: A Multi-center Cross-sectional Study

Background

Epilepsy accounts for 0.5 % of the world's disease burden. Around 80 % of these are living in low and middle-income countries. In Ethiopia, the prevalence is 0.6 to 5 per 1000 population. There is a little study in our study area on the treatment and predictors of response of adult epilepsy. The purpose of this study was to determine the treatment outcome and its associated factors among adult epileptic patients in public hospitals in southern Ethiopia.

Methods

Multi-centered, Hospital-based cross-sectional study was conducted from October 2021 - august 2022. Data were collected by face-to-face interviews and record review. Data was analysed using SPSS. The bivariate and multivariable logistic regression analyses have been performed between the dependent and the independent variables.

Result

Of the total 422 participants, 55.9 % were males and 62.6% were below 30 years of age. The most common type of seizure was a generalized tonic-clonic seizure. Most (87.9 %) were treated by immunotherapy. Phenobarbitone is most common medication (77.5). One-quarter reported adverse effects of medication. The majority (78%) had good control (seizure free for at least one year) and 22% had poor control. Poor medication adherence (AOR=4.03) and shorter duration of seizure before treatment (AOR=4.233) were associated with poor control.

Conclusion

A significant number of patients had poor control of seizures. Early identification of issues on medication adherence and early initiation of treatment will improve treatment outcome.

Treatment outcome and associated factors among epileptic patients at ambulatory clinic of Mettu Karl Comprehensive Specialized Hospital: A cross-sectional study

Objective

The study was aimed to assess the magnitude and associated factors of 2-year seizure-free status of epileptic patients at Mettu Karl Comprehensive Specialized Hospital (MKCSH).

Methods

A retrospective cross-sectional study was conducted at MKCSH from 12 February 2020 to 11 August 2020. Treatment outcome was measured in terms of seizure control status and seizure frequency. Accordingly, good treatment outcome was declared if the patients had a 2-year seizure-free status and poor if the patient had episodes of seizure in the last 2 years. The pharmaceutical care network Europe guideline was used to assess the presence of medication-related problems. Multivariable logistic regression was used to analyze the variables by using crude odds ratio (COR) and adjusted odds ratio (AOR) with 95% confidence interval (CI). Finally, the predictors of epilepsy treatment outcome were declared if a P-value was ⩽0.05.

Results

Over the study period, more than half of the participants (172 (57.7%)) were males. The median age of participants was 29 and majorly distributed to 18-30 classes. More than one-fourth of the patients were suffering from absent seizure 85 (28.5%) and general tonic-clonic seizure 83 (27.9%). The most commonly prescribed medication was Phenobarbitone which accounts 34 (11.41%), whereas Valproic acid 8 (2.68%) was the least prescribed. Overall, less than half 131 (43.96%) of patients developed poor treatment outcomes. The predictors of treatment outcomes were having head the injury (AOR = 5.7; 95% CI: 3.18, 10.31), family history of epilepsy (AOR = 5.6; 95% CI: 3.07, 10.46) and the presence of drug therapy problems (AOR = 5.2; 95% CI: 2.79, 9.69).

Conclusion

The magnitude of poor epilepsy treatment outcome was found to be high. The predictors of epilepsy treatment outcome were the history of head injury, family history of epilepsy and drug therapy problems. Therefore, to improve the treatment outcome of epileptic patients, health care providers should pay close attention to the identified factors. Besides this, the clinical pharmacy service should be implemented to minimize any medication-related problems.

Seizure control and its associated factors among epileptic patients at Neurology Clinic, University of Gondar hospital, Northwest Ethiopia

Background

Epilepsy is characterized by two or more unprovoked recurrent seizures, which often respond to available antiseizure medications. However, seizure control among epileptic patients in the developing world is low. Factors determining seizure control among epileptic patients were not evidently explored in the study setting.

Objectives

This study aimed to determine the magnitude of uncontrolled seizures and associated factors among epileptic patients at the University of Gondar hospital.

Methods

This cross-sectional study was conducted at the University of Gondar hospital, Northwest Ethiopia. A convenience sampling method was used to recruit study subjects. Controlled seizure was defined as seizure freedom for the past 1 year. Logistic regression analysis was used to identify factors associated with seizure control. A p-value < 0.05 was used to declare a significant association.

Results

A total of 320 study subjects were included in the study. The mean (±SD) age of patients was 27.5 ± 7.6 years. More than half (182/320, 57%) of epileptic patients had uncontrolled seizures. Five or more pretreatment seizure episodes (adjusted odds ratio = 3.98, 95% confidence interval: 1.81-8.75, p = 0.001), less than 2 years on anti-seizure medications (adjusted odds ratio = 8.64, 95% confidence interval: 3.27-22.85, p < 0.001), taking 2 or more ASMs (adjusted odds ratio = 2.48, 95% confidence interval: 1.23-5.02, p = 0.011), poor adherence to ASMs (adjusted odds ratio = 9.37, 95% confidence interval: 4.04-21.75, p < 0.001), and living at a single trip distance from hospital equaled 1 h or more (adjusted odds ratio = 4.20, 95% confidence interval: 2.11-8.41, p < 0.001) were significantly associated with uncontrolled seizures.

Conclusion

The dose of a preferred anti-seizure medication should be optimized before combinations of anti-seizure medications are used. Adherence to anti-seizure medications should be reinforced for better seizure control. Epilepsy care should be integrated into primary health care services in the catchment region.

Significant Association of Antiepileptic Drug Polytherapy with Decreased FT4 Levels in Epileptic Patients

Epileptic patients have to continue anti-epileptic drugs (AED) over a long period of time which can have deleterious effects on the endocrine system including the thyroid hormones with rare check. Risk factors for the development of thyroid dysfunction are still unclear. Therefore the aim of study was to evaluate thyroid functions in epileptic patients receiving anti-epileptic drugs (AED) as monotherapy and polytherapy and to determine potential risk of low thyroid function in epileptic patients receiving treatment. This cross-sectional study included 100 epilepsy patients more than 12 years of age. Serum levels of free thyroxin (FT4), free triiodothyronine (FT3), and thyroid stimulating hormone (TSH) were evaluated in all subjects in addition to serum AED levels. TSH levels were found to be significantly higher in the polytherapy subgroup (p < 0.05) in comparison to the monotherapy group. 44% of the patients in the VPA monotherapy group had raised TSH levels and 41.2% of the patients on CBZ had low FT4. A significant negative correlation was observed between CBZ and FT4 (p < 0.05). Female sex and old age were additional risk factors detected for deranged thyroid function. Female patients with epilepsy, an older age and AED polytherapy were found to be associated with a higher risk of thyroid dysfunction. Thus, Thyroid function in these patients should be monitored closely. In conclusion, we observed significant changes in thyroid hormone levels in patients receiving antiepileptic treatment in both monotherapy and polytherapy. Elevated CBZ levels were significantly associated with decreased FT4 levels.

Non-Adherence to Antiepileptic Drugs and Associated Factors among Epileptic Patients at Ambulatory Clinic of Southwestern Ethiopian Hospital: A Cross-Sectional Study

BACKGROUND

Non-adherence to anti-epileptic drugs (AEDs) was the most common drug therapy issue that hampered epileptic patients' treatment success. As a result, the barriers to patients adhering to their treatment should be investigated in depth in order to prevent poor treatment outcomes.

METHODS

A hospital-based cross-sectional study was conducted on epileptic patients who had followed up at Mettu Karl Comprehensive Specialized Hospital (MKCSH). Data collection was done through patient interview and medical charts review. Hill-Bone Compliance to High Blood Pressure Therapy Scale was used to measure medication adherence. The data were analyzed using SPSS version 23 after data were entered by Epi Info7.2.1. The multivariable logistic regressions were utilized and P < 0.05 was used to declare association.

RESULTS

Over the study period, more than half of the participants 172 (57.7%) were males, and the median age of participants was 29 years. The magnitude of non-adherence to ant-epileptic drugs (AEDs) was 120 (40.27%). The results of multivariable analysis revealed that patients who had experienced the medication side effects, adjusted odds ratio (AOR) = 2.199; 95% CI: 1.21, 4.00, P = 0.010, a poly-pharmacy, adjusted odds ratio (AOR) = 5.166; 95% CI: 2.63, 10.14, P = <0.001 and the presence of a co-morbidity, adjusted odds ratio (AOR) =3.70; 95% CI: 2.058, 6.65, P = <0.001 were the predictors of medication non-adherence.

CONCLUSION

The magnitude of non-adherences to AEDs was found to be high. Phenobarbitone was the most prescribed AEDs. The number of medications taken by the patients, the presence of co-morbidity and the occurrence of medication side effects had a significant association with non-adherence to AEDs. Therefore, the pharmaceutical care in general and drug information services in particular should be established to enhance medication adherence in our study area.

Role of clinical pharmacists in epilepsy management at a general hospital in Vietnam: a before-and-after study

Background

Clinical pharmacists have an important role in inter-professional healthcare collaboration for epilepsy management. However, the pharmacy practices of managing epilepsy are still limited in Vietnam, deterring pharmacists from routine adjustments of antiepileptic drugs, which could decrease the patients’ quality of life. This study aimed to assess the effectiveness of pharmacist interventions in epilepsy treatment at a Vietnamese general hospital.

Methods

A before-and-after study was conducted from January 2016 to December 2018. All patients with a diagnosis of epilepsy and being treated at the investigated hospital were recruited and screened for eligibility and exclusion criteria. The primary outcome was the proportion of patients in good control of their epilepsy (with two seizures or less in a year). The secondary outcome was the number of patients maintaining optimized concentrations within the therapeutic range of carbamazepine (4–12 mg/L), phenytoin (10–20 mg/L), or valproic acid (50–100 mg/L). Collected data were analyzed using two proportions Z-test or Chi-square test.

Results

A total of 141 participants were enrolled in the study. While most patients were given lower prescribed daily doses than the recommendations from the World Health Organization, over 56% of the participants still experienced adverse drug effects. More than half of the patients received at least one pharmacists’ intervention, which increased by 25.0% the effectiveness of the therapy (p < 0.001) and by 14.6% the number of patients with optimized drug concentrations (p = 0.018).

Conclusion

Epilepsy management requires a multiple-stepped and comprehensive approach, with a focus on the health and safety of the patients. As part of the healthcare team, pharmacists need to engage at every stage to monitor the patient’s response and determine the most effective treatment with the fewest adverse drug reactions.

Treatment Outcome of Epileptic Patients Receiving Antiepileptic Drugs in Ethiopia: A Systematic Review and Meta-Analysis

Background

The prevalence and incidence rate of epilepsy were found to be higher in low- and middle-income countries. Uncontrolled epilepsy has a high risk of disability, stigma, discrimination, human rights violations, and premature death. The available studies of controlled seizure in Ethiopia have showed inconsistent results which calls for systematic review and meta-analysis. Therefore, this review intended to show the pooled prevalence of controlled seizure among people with epilepsy receiving antiepileptic drugs at outpatient department.

Methods

A systematic literature search was conducted using PubMed/Medline, Science Direct, PsycINFO, Hinnarri databases, and Google Scholar for grey literatures. Data were extracted with structured format prepared using Microsoft Excel and exported to Stata/MP 16.0 software for analyses. The I² test was used to check the heterogeneity between primary studies with a corresponding 95% confidence interval (CI).

Results

A total of 23 primary studies were included in the review showing the pooled prevalence of controlled seizure to be 46% (95% CI: 35, 56). A subgroup analysis of the primary studies showed a considerable variation in magnitude of seizure freedom by study regions, age groups, and seizure-free period. The highest prevalence was found in Addis Ababa 52% (95% CI: 29, 75), pediatric patients 77% (95% CI: 71, 83), and a seizure-free period of less than six months 58% (95% CI: 32, 83). On the other hand, the lowest prevalence of controlled seizure was found in Tigray 27% (95% CI: 11, 65), adult patients 43% (95% CI: 32, 54), and a seizure-free period of six or more 41% (95% CI: 32, 51). Higher frequency of seizure before treatment (2.23, 95% CI: 1.15, 3.31) and medication nonadherence (2.7, 95% CI: 1.25, 4.15) had statistically significant association with uncontrolled seizure.

Conclusion

In this review, the prevalence of controlled seizure was found to be low. This warrants that clinicians should give more focus to epileptic patients regarding monitoring and evaluation of treatment outcome of epilepsy and factors that affect seizure control in routine clinical services. The use of standardized definition of controlled seizure, designing strategies to identify pharmacoresistant epilepsy and its treatment, and increasing medication adherence are recommended in Ethiopia. The review protocol has been registered with PROSPERO registration number CRD42021215302.

A reappraisal of injuries and accidents in people with epilepsy

PURPOSE OF REVIEW

We review data on injuries and traffic accidents affecting people with epilepsy with emphasis on the overall risk of injuries, specific types of injuries, and risk factors.

RECENT FINDINGS

Population-based studies of incident epilepsy cohorts indicate that the risk of physical injuries in people with epilepsy in general is increased only modestly. The risk is higher in selected populations that attend epilepsy clinics or referral centers. Soft tissue injuries, dislocations, and fractures are the most common injures, whereas the greatest increase in risk is reported for more uncommon injuries such as drowning. People with epilepsy are at a two-fold to four-fold increased risk for fatal injuries. Comorbidities contribute to fatal as well as nonfatal injuries. The other major risk factor is poorly controlled major convulsive seizures (generalized as well as focal to bilateral tonic-clonic seizures). Serious transport accidents associated with increased risks for people with epilepsy include pedestrian, bicycle, as well as car accidents.

SUMMARY

Individualized information on the risk of physical injuries and accidents should be part of counseling of patients with epilepsy. Improved seizure control is likely the most effective way to reduce risks, but work place and home adjustments should also be considered.

Nonadherence to Antiepileptic Medications and Its Determinants among Epileptic Patients at the University of Gondar Referral Hospital, Gondar, Ethiopia, 2019: An Institutional-Based Cross-Sectional Study

Introduction

Nonadherence to antiepileptic medication is the extent of a patient's passive failure to follow the prescribed therapeutic regimen. The prevalence and impact of nonadherence to antiepileptic medication are high globally. The main purpose of this study was to assess nonadherence to antiepileptic medications and its associated factors among epileptic patients at the University of Gondar Referral Hospital, Gondar, Ethiopia, 2019.

Methods

An institutional-based cross-sectional study was conducted among 365 epileptic patients at the University of Gondar Referral Hospital, who were selected by a systematic random sampling technique. Data were collected by face to face interviews using a structured pretested questionnaire. Data were entered into EPI Info version 7 and then exported to SPSS version 22 for analysis. The data were described by descriptive statistics. Binary logistic regression analysis was used as a model, and variables with a p value of less than 0.05 were considered as statistically significant with nonadherence to antiepileptic medications.

Results

A total of 356 epileptic patients participated in the study yielding a response rate of 97.5%. The overall prevalence of nonadherence to antiepileptic medications among epileptic patients attending at the University of Gondar Referral Hospital was 38.5% (95% CI: 33.1–43.8). Divorced and/or widowed marital status (AOR: 3.38 (95% CI: 1.54, 7.44)), treatment duration of 3–5 years (AOR = 3.58 (95% CI: 1.38, 9.29)), treatment duration of 5 and above years (AOR: 3.49 (95% CI: 1.53, 7.95)), comorbidity (AOR: 2.42 (95% CI: 1.08, 5.43)), side effects of antiepileptic medications (AOR: 3.36 (95% CI: 1.67, 6.74)), absence of health information (AOR: 1.98 (95% CI: 1.11, 3.52)), epilepsy-related stigma (AOR: 2.81 (95% CI: 1.57, 5.02)), and negative attitude towards antiepileptic medications (AOR: 2.46 (95% CI: 1.36, 4.45)) were significantly associated with nonadherence to antiepileptic medications.

Conclusions

Prevalence of nonadherence to antiepileptic medications among epileptic patients at the University of Gondar Referral Hospital was found to be high. Hence, giving health information about epilepsy and its management will help to reduce antiepileptic medications' nonadherence.
