Models of community-based primary care for epilepsy in low- and middle-income countries

The impact of a newly established specialized pediatric epilepsy center in Tanzania: An observational study

PURPOSE

This study evaluated the impact of a newly established clinic for the diagnosis of pediatric epilepsy in a resource-limited center (Ifakara, Tanzania).

METHODS

Patients aged 0-18 years referred to the Pediatric Epilepsy Unit of Saint Francis Referral Hospital were recruited. Demographic and clinical data were collected through Kobo Toolbox and analyzed through a descriptive analysis..

RESULTS

143 patients were evaluated, and for 48 of them an EEG was recorded (abnormalities were detected in 80.85% of the cases). The diagnosis of epilepsy was confirmed in 87 patients. Focal epilepsy was diagnosed in 57 patients, generalized epilepsy in 24 patients, and forms of unknown onset in 6 patients. Epilepsy was excluded for 9 children. Etiologies included hypoxic-ischemic encephalopathy (39%), central nervous system infections (3.4%), and genetic diseases (3.4%). A specific epilepsy syndrome was diagnosed in 16 patients. 74 patients were under treatment; the most used antiseizure medication (ASM) was phenobarbital (43.36%), followed by carbamazepine (16.08%), sodium valproate (11.19%), phenytoin (2.8%), and lamotrigine (0.7%). Therapeutic changes were proposed to 95 patients, more frequently consisting of withdrawing phenobarbital (39.16%), switching to sodium valproate (27.97%), switching to or adjusting carbamazepine dosage (27.27%), and starting prednisone (2.8%). 76% of the patients with confirmed epilepsy achieved complete seizure freedom at the fourth follow-up consultation.

CONCLUSIONS

Our data depicted the epilepsy spectrum and highlighted the prognostic implications of improving the availability of ASMs such as sodium valproate and second- and third-generation ones in resource-limited countries.

Implementing WHO's Intersectoral Global Action Plan for epilepsy and other neurological disorders in Southeast Asia: a proposal

The World Health Assembly approved the Intersectoral Global Action Plan for epilepsy and neurological disorders. Member states, including those in Southeast Asia, must now prepare to achieve IGAP's strategic targets by embracing novel approaches and strengthening existing policies and practices. We propose and present evidence to support four such processes. The opening course should engage all stakeholders to develop people-centric instead of outcome-centric approaches. Rather than caring for convulsive epilepsy alone, as currently done, primary care providers should also be skilled in diagnosing and treating focal and non-motor seizures. This could reduce the diagnostic gap as over half of epilepsies present with focal seizures. Currently, primary care providers lack knowledge and skills to manage focal seizures. Technology-enabled aids can help overcome this limitation. Lastly, there is need to add newer "easy to use" epilepsy medicines to Essential Medicines lists in light of emerging evidence for better tolerability, safety and user-friendliness.

A cluster-randomized trial comparing home-based primary health care and usual clinic care for epilepsy in a resource-limited country

OBJECTIVE

To ascertain whether home-based care with community and primary healthcare workers' support improves adherence to antiseizure medications, seizure control, and quality of life over routine clinic-based care in community samples of people with epilepsy in a resource-poor country.

METHODS

Participants included consenting individuals with active epilepsy identified in a population survey in impoverished communities. The intervention included antiseizure medication provision, adherence reinforcement and epilepsy self- and stigma management guidance provided by a primary health care-equivalent worker. We compared the intervention group to a routine clinic-based care group in a cluster-randomized trial lasting 24 months. The primary outcome was antiseizure medication adherence, appraised from monthly pill counts. Seizure outcomes were assessed by monthly seizure aggregates and time to first seizure and impact by the Personal Impact of Epilepsy scale.

RESULTS

Enrolment began on September 25, 2017 and was complete by July 24, 2018. Twenty-four clusters, each comprising ten people with epilepsy, were randomized to either home- or clinic-care. Home-care recipients were more likely to have used up their monthly-dispensed epilepsy medicine stock (regression coefficient: 0.585; 95% confidence intervals, 0.289-0.881; P = 0.001) and had fewer seizures (regression coefficient: -2.060; 95%CI, -3.335 to -0.785; P = 0.002). More people from clinic-care (n = 44; 37%) than home-care (n = 23; 19%) exited the trial (P = 0.003). The time to first seizure, adverse effects and the personal impact of epilepsy were similar in the two arms.

SIGNIFICANCE

Home care for epilepsy compared to clinic care in resource-limited communities improves medication adherence and seizure outcomes and reduces the secondary epilepsy treatment gap.

Burden, Disability and Public Health Importance of Headache Disorders in India

Headache disorders, characterized by recurrent headache, are among the most common disorders of the nervous system. The aim of this study was to document epidemiological and economic burden due to headache globally and in India and suggest a public health approach to address headache disorders for India. We reviewed the available literature on burden due to headache, its management using a primary health care approach and health system barriers, with special emphasis on India. Globally, it has been estimated that prevalence of current headache disorder (symptomatic within last year) among adults is about 50%, around 30% report migraine and headache on 15 or more days every month affects 1.7-4% people. The Global Burden of Disease Study 2016 estimated that migraine caused 45·1 million (95% UI 29·0-62·8) and tension-type headache 7·2 million (95% UI 4·6-10·5) years of life lived with disability. Limited data available in India support such high burden. These studies also indicate high diagnostic and treatment gaps for headache disorders in India. Major challenges in addressing headache disorders effectively in India are low perceived severity, absence of burden data, lack of standard treatment protocols for headache disorders and primary care models for neurological disorders in developing country context. There needs to be a better appreciation of the burden and a public health approach among all stakeholders, if burden of headache disorders is to be addressed effectively in India.

The impact of COVID-19 pandemic on frail health systems of low- and middle-income countries: The case of epilepsy in the rural areas of the Bolivian Chaco

INTRODUCTION

The Coronavirus disease 2019 (COVID-19) has put some health systems under pressure, especially in low- and middle-income countries. We aimed at evaluating the impact of COVID-19 emergency on the management of people with epilepsy (PWE) living in the rural communities of the Gran Chaco area of the Plurinational State of Bolivia.

MATERIALS AND METHODS

We selected a sample of PWE living in the rural communities of the Bolivian Chaco. A standardized questionnaire was developed, consisting of six questions addressing drug availability, drug discontinuation, personnel responsible for drug retrieval during the lockdown, and the presence of seizures in the two months preceding the interview. Questionnaires were administered by community health workers of the rural health centers in September 2020.

RESULTS

Seventy PWE (38 men, 54.3%; mean age 26.9 ± 16.7) were interviewed. During the lockdown the large majority of them (n = 51, 73.9%) reported an irregular medication intake mainly due to the lack of antiseizure medications in the local health posts, leading to an increase in seizure frequency.

CONCLUSION

The COVID-19 pandemic has unmasked the frailty of the Bolivian health system, especially for the management of chronic diseases such as epilepsy in the rural communities.

Clinical characteristics of epilepsy in resource-limited communities in Punjab, Northwest India

OBJECTIVES

To describe clinical characteristics of a community-based epilepsy cohort from resource-limited communities in Punjab, Northwest India.

METHODS

The cohort was gathered following a two-stage screening survey. We cross-sectionally examined and followed up the cohort for one year. A panel of neurologists assigned seizure types, syndromes, and putative etiologies and categorized drug responsiveness.

RESULTS

The cohort of 240 included 161 (67.1%) men, 109 (45.4%) illiterates and 149 (62.1%) unemployed. Current age was >18 years in 155 (64.6%) but age at epilepsy onset was <18 years in 173 (72.1%). Epilepsies due to structural and metabolic causes were diagnosed in 99 (41.3%), but syndromic assignments were not possible in 97 (40.4%). After one year, drug-resistant epilepsy was established in 74 (30.8%). Perinatal events (n = 35; 14.6%) followed by CNS infections (n = 32; 13.3%) and traumatic brain injury (n = 12; 5.0%) were common risk factors. Most of those with CNS infections (n = 19; 63.3%), perinatal antecedents (n = 23; 76.7%), and other acquired risk factors (n = 27; 90.0%) presented with epilepsy due to structural and metabolic causes. Perinatal events were the putative etiology for nearly 40.7% of generalized epilepsies due to structural and metabolic causes and 28.2% of all epilepsies with onset <10 years.

SIGNIFICANCE

Existing classifications schemes should be better suited to field conditions in resource-limited communities in low- and middle-income countries. The finding of drug-resistant epilepsy in nearly at least a third in a community-based sample underscores an unmet need for enhancing services for this segment within healthcare systems. Perinatal events, CNS infections, and head injury account for a third of all epilepsies and hence preventative interventions focusing on these epilepsy risk factors should be stepped up.

Development and Evaluation of a Pediatric Epilepsy Training Program for First Level Providers in Zambia

Introduction. The developing world continues to face challenges in closing the large treatment gap for epilepsy, due to a high burden of disease and few experienced providers to manage the condition. Children with epilepsy are susceptible to higher rates of developmental impairments and refractory disease due to delays or absence of appropriate management as a result. We demonstrated that a structured education intervention on pediatric epilepsy can improve knowledge, confidence, and impact clinical practice of first level providers in Zambia. Methods. Three first-level facilities across Zambia were included. After initial pilot versions and revisions, the final course was implemented at each site. Pre- and post-intervention knowledge and confidence assessments were performed. Additionally, chart reviews were conducted prior to intervention and 4 months after completion of training at each site to assess change on management. Results. Twenty-three of the original 24 participants from all 3 sites completed the training; 48% clinical officers, 43% nurses, 9% other expertise. Of the 15 concepts tested by knowledge assessment, 12 showed trends in improvement, 7 of which were significant (P < .05). Chart reviews demonstrated significant improvement in documentation of seizure description (P = .008), seizure frequency (P = .00), and possible causes of seizures/epilepsy (P = .034). Discussion. Key elements of success to this program included hands on clinical skills building and case-based teaching, development of a program with direct and ongoing input from the target audience, and inclusion of assessments to monitor impact on clinical practice. Future studies looking at health outcomes are necessary to determine sustained impact.

Mortality implications and factors associated with nonengagement in a public epilepsy care initiative in a transient population

BACKGROUND

Community-based, public care programs are a requisite to close the epilepsy treatment gap in disadvantaged communities in low- and middle-income countries (LMICs). Potential beneficiaries may, however, choose not to engage in these programs.

AIMS

The aim of the study was to describe factors associated with and mortality consequences of nonacceptance of a public epilepsy care initiative.

METHODS

In this cross-sectional study, we contacted 207 (36%) people out of 575 who screened positive for epilepsy during a population-based survey of 59,509 people. They were invited for neurological evaluation and care provision (including antiseizure medications (ASMs)) but chose not to engage. Structured questionnaires and qualitative interviews were conducted to determine reason for their nonengagement. Factors associated with nonengagement were evaluated by univariate and multivariate analysis. We conducted verbal autopsies for those who had died.

RESULTS

Ten (5%) of the 207 individuals died since the initial screening; six with epilepsy-related causes. Of those who could be contacted (n = 48), 40 (19%) were confirmed to have epilepsy. Nonengaging individuals were likely to be older (odds ratio (OR): 1.02; 95% confidence interval (CI), 1.01, 1.11), locals (OR: 4.32; 95% CI, 1.55, 12.03), and earn less than US$ 78/month (OR: 3.6; 95% CI, 1.62, 8.06). Reasons for not engaging included a belief that epilepsy is inconsequential, loss of daily wages owing to healthcare facility visit and physical infirmity.

CONCLUSIONS

Nonacceptance of a community-based public epilepsy care initiative is associated with high premature mortality, mostly attributed to epilepsy-related causes. Older age, ethnic status, and economic deprivation are factors associated with nonacceptance, though the underlying reasons may be varied.

Community-based management of epilepsy in Southeast Asia: Two intervention strategies in Lao PDR and Cambodia

Background

Epilepsy affects more than 50 million people worldwide, 80% of whom live in low- and middle-income countries (LMICs). In Southeast Asia, the prevalence is moderate (6‰), and the main public health challenge is reducing the treatment gap, which reaches more than 90% in rural areas.

Methods

This 12-month comparative study (intervention vs. control areas) assessed the community effectiveness of two different strategies for the identification and home follow-up of people with epilepsy by Domestic Health Visitors for epilepsy (DHVes). In Lao PDR, DHVes were health center staff covering several villages via monthly visits; in Cambodia, DHVes were health volunteers living in the villages.

Findings

At baseline, the treatment gap was >95% in Lao PDR and 100% in Cambodia. After 12 months, the treatment gap in Lao PDR decreased by 5·5% (range: 4·0–12·2) in the intervention area and 0·5% (range: 0·4–0·8) in the control area (p<0·0001). In Cambodia, the treatment gap decreased by 34·9% (range: 29·0–44·1) in the intervention area and 8·1% (range: 6·7–10·2) in the control area (p<0·0001). Among the PWEs followed at home by the DHVes, the proportion adhering to drug treatment was 85·2% in Lao PDR and 78·1% in Cambodia. The cost associated with strategy implemented in Cambodia, compared with the control area, was lower than the cost associated with strategy implemented in Lao PDR.”

Interpretation

The treatment gap was significantly reduced with both intervention strategies, but the effect was larger in Cambodia. The results of this cost analysis pave the way for scaling-up in rural areas of Lao PDR and Cambodia, and experimental adaptation in other LMICs.

Funding

The study was funded by the Global Health Department of Sanofi and Grand Challenges Canada (grant number 0325–04).
