Medication prescribing and patient-reported outcome measures in people with epilepsy in Bhutan

Depression, sleep quality, and social isolation among people with epilepsy in Bhutan: A cross-sectional study

PURPOSE

The aim of this study was to analyze the possible contributions of seizure burden, sleep quality, and social integration to depression among people with epilepsy (PWE) in Bhutan.

METHODS

Bhutan is a lower-middle-income country in Southeast Asia with a public healthcare system without neurologists. People with epilepsy were prospectively recruited from psychiatrist-run epilepsy clinics at the National Referral Hospital in the capital city of Thimphu. Adult participants with epilepsy were interviewed for clinical history, sleep quality using the Pittsburgh Sleep Quality Index, social networks using the Berkman-Syme Social Network Index, and depressive symptoms using the Patient Health Questionnaire - 9 (PHQ-9). A multivariable regression model was built to assess the relationship between depression as an outcome and the possible contributors of sleep quality, sex, and seizure in the prior month.

RESULTS

Out of 80 participants (39 women, mean age: 29.4 years old, range: 18-56 years, 58 [73%] with a seizure in the previous month), 33% had poor sleep quality, 68% were socially isolated, 30% had a mild depressive symptom burden or more, and 18% reported suicidal ideation at the time of their interview. Women had a higher average PHQ-9 score versus men, which showed a trend towards statistical significance (5.6 versus 3.3 PHQ-9 points, p = 0.07), and on average met criteria for mild depression. Social integration was not significantly associated with sleep quality and had no relationship with depressive burden. There was a small positive correlation between poorer sleep quality and depressive symptoms which showed a trend towards statistical significance (r = 0.21, p = 0.06). In a multivariable regression, poor sleep quality was associated with higher depressive symptom burden, adjusting for participant sex and having a seizure in the previous month (p = 0.01).

CONCLUSIONS

Our exploratory study disentangles the multilayered psychosocial burden of disease experienced by PWE in Bhutan, a lower-middle-income country with access to antiseizure medications and psychiatrists but not expert epilepsy services or human resources. Further investigation into the interrelationships among social isolation, poor sleep quality, depression, and seizure burden could identify preventable and remediable constituents of this burden.

Parkinson's Disease in the Middle East, North Africa, and South Asia: Consensus from the International Parkinson and Movement Disorder Society Task Force for the Middle East

BACKGROUND

Understanding the regional needs and available healthcare resources to treat Parkinson's disease (PD) is essential to plan appropriate future priorities. The International Parkinson and Movement Disorder Society (MDS) Task Force for the Middle East was established to raise awareness and promote education across the region on PD and other movement disorders. Broadly, the task force encompasses the countries of the Middle East but has included North Africa and South Asia as well (MENASA).

OBJECTIVE

To create a list of needs and priorities in the advancement of PD in MENASA countries based on consensuses generated by the MDS task force for the Middle East.

METHODS

A Strengths Weaknesses-Opportunities-Threats (SWOT) analysis was conducted by the task force members to generate consensus about PD care this region.

RESULTS

Eight overarching principles emerged for the consensus statement on current needs: more movement disorders specialists, multidisciplinary care, accurate epidemiologic data, educational programs, availability of drugs, and availability of more advanced therapy, enhanced health care resources and infrastructure, and greater levels of awareness within the general population and among health care professionals.

CONCLUSION

This pilot study sheds light on unmet needs for providing care to people with PD in the MENASA region. These data offer directions on priorities to increase awareness of PD, to develop better infrastructure for research and management of PD, to foster healthcare policy discussions for PD and to provide educational opportunities within these countries.

Missed opportunities for epilepsy surgery referrals in Bhutan: A cohort study

OBJECTIVE

To quantify the missed opportunities for epilepsy surgery referral and operationalize the Canadian Appropriateness of Epilepsy Surgery (CASES) tool for use in a lower income country without neurologists.

METHODS

People with epilepsy were recruited from the Jigme Dorji Wangchuck National Referral Hospital from 2014-2016. Each participant was clinically evaluated, underwent at least one standard EEG, and was invited to undergo a free 1.5 T brain MRI. Clinical variables required for CASES were operationalized for use in lower-income populations and entered into the free, anonymous website tool.

FINDINGS

There were 209 eligible participants (mean age 28.4 years, 56 % female, 179 with brain MRI data). Of the 179 participants with brain MRI, 43 (24.0 %) were appropriate for an epilepsy surgery referral, 21 (11.7 %) were uncertain, and 115 (64.3 %) were inappropriate for referral. Among the 43 appropriate referral cases, 36 (83.7 %) were "very high" and 7 (16.3 %) were "high" priorities for referral. For every unit increase in surgical appropriateness, quality of life (QoL) dropped by 2.3 points (p-value <0.001). Among the 68 patients who took >1 antiepileptic drug prior to enrollment, 42 (61.8 %) were appropriate referrals, 14 (20.6 %) were uncertain, and 12 (17.6 %) were inappropriate.

CONCLUSION

Approximately a quarter of Bhutanese epilepsy patients who completed evaluation in this national referral-based hospital should have been evaluated for epilepsy surgery, sometimes urgently. Surgical services for epilepsy are an emerging priority for improving global epilepsy care and should be scaled up through international partnerships and clinician support algorithms like CASES to avoid missed opportunities.

A cascade of care for people with epilepsy: learning from "HIV/AIDS 90-90-90"

Epilepsy is now more prevalent in many countries than HIV/AIDS. Building upon the advances of global policymaking for HIV/AIDS and creating a framework for countries and organizations to monitor progress in epilepsy care will help direct and justify much-needed novel programming. Given the clarity of the HIV/AIDS care continuum model and the UNAIDS 90-90-90 targets, I propose this same approach to the cascade of care could be used as a viable framework for people with epilepsy. In this model, the targets of success include (1) ensuring 90% of all people with epilepsy are aware of their diagnosis as a brain disorder, (2) starting 90% of people with epilepsy on quality controlled, appropriately chosen and well stocked antiepileptic drugs, and (3) achieving seizure freedom in 70% of those treated. At least 90% of all people with epilepsy must also be linked to and retained in appropriate care. Although the precise numbers may be debated, this cascade of care approach will assist in deconstructing the barriers to epilepsy care in populations better than the more familiar concept of the epilepsy treatment gap. These reflect concrete goals for health systems for epilepsy care that, if achieved, could lead to seizure freedom for the many people in lower income countries living with poorly controlled epilepsy.

Caring electronically for young outpatients who have epilepsy

PURPOSE

The purpose of this study was to review electronic tools that might improve the delivery of epilepsy care, reduce medical care costs, and empower families to improve self-management capability.

METHOD

We reviewed the epilepsy-specific literature about self-management, electronic patient-reported or provider-reported outcomes, on-going remote surveillance, and alerting/warning systems.

CONCLUSIONS

The improved care delivery system that we envision includes self-management, electronic patient (or provider)-reported outcomes, on-going remote surveillance, and alerting/warning systems. This system and variants have the potential to reduce seizure burden through improved management, keep children out of the emergency department and hospital, and even reduce the number of outpatient visits.

The economic burden of epilepsy in Bhutan

OBJECTIVE

To assess the economic impact of epilepsy in Bhutan, a lower-middle-income country with a universal health care system, but with limited access to neurological care.

METHODS

A cross-sectional survey was conducted of patients with epilepsy at the Jigme Dorji Wangchuk National Referral Hospital from January to August 2016. Data were collected on clinical features, cost of care, impact of epilepsy on school or work and household economic status of participants and matched comparisons (a sibling or neighbour from a household without epilepsy).

RESULTS

A total of 172 individuals were included in the study (130 adults and 42 children). One-third of adults and 20 (48%) children had seizures at least once per month. Mean direct out-of-pocket cost for epilepsy care was 6054 Bhutanese Ngultrum (BTN; 91 USD) per year, of which transportation formed the greatest portion (53%). Direct costs of epilepsy were an average of 3.2% of annual household income. Adults missed 6.8 (standard deviation [SD]: 9.0) days of work or school per year on average, and children missed 18.6 (SD: 34.7) days of school. Among adults, 23 (18%) abandoned employment or school because of epilepsy; seven children (18%) stopped school because of epilepsy. Households with a person with epilepsy had a lower monthly per-person income (6434 BTN) than comparison households without epilepsy (8892 BTN; P = 0.027).

CONCLUSIONS

In Bhutan, despite universal health care services, households of people with epilepsy face a significant economic burden. With many adults and children unable to attend school or work, epilepsy causes a major disruption to individuals' livelihoods.

Contraception, pregnancy, and peripartum experiences among women with epilepsy in Bhutan

INTRODUCTION

Reports on the reproductive health of women with epilepsy (WWE) in low- and middle-income countries (LMICs) are limited. Bhutan is a lower income country with a high estimated prevalence of epilepsy and no out-of-pocket payment requirements for health visits or medications.

METHODS

We developed a 10-category survey to interview WWE ages 20-59 years in the Kingdom of Bhutan to understand their contraceptive use and peripartum experiences. WWE were recruited from 2016-2017 from an existing epilepsy cohort and their reproductive health data were merged with epilepsy and socioeconomic data obtained from initial clinical evaluations performed between 2014 and 2016.

RESULTS

Of the 134 WWE eligible for the study, 94 were reachable and there was 1 refusal to participate (response rate 99% among reachable WWE; 69% of all WWE in the cohort). Of the 93 WWE (median age 27 years, range 20-52), 50 (54%) reported prior pregnancies. Of the entire cohort, 55 women responded on contraception: 26 (47%) WWE had never used contraception in their lifetime. Of the 29 WWE who had ever used contraception, the most commonly reported form was male condoms (14/29, 48%), followed by depot medroxyprogesterone acetate injections (13/29, 45%), and intrauterine devices (5/29, 17%). Sixty-three percent of WWE recalled receiving information on family planning (31 of 49). Of the 50 WWE with prior pregnancies, 37 of 46 (80%) used folic acid; 6 WWE reported commencing it in the first trimester while 29 WWE began supplementation in the second trimester. Primary school education or higher was associated with folic acid supplementation during pregnancy (26/29 vs. 11/17, p=0.040). Epilepsy affected at least one of the pregnancies in 38 of the cases (76%) with an average of 2.3 pregnancies per woman). There was a total of 86 pregnancies and an average inter-pregnancy interval of 3.5 years. Ninety-five percent of women attended prenatal care (36/38), 22% had at least one miscarriage (8/37), 14% had at least one pre-term delivery (5/36), and 21% had Caesarean sections (8/38). Seventeen of 38 (45%) of WWE had seizures during pregnancy. A majority of WWE (97%, 37 of 38) with a prior pregnancy reported breastfeeding their infant.

CONCLUSIONS

Nearly half of Bhutanese WWE did not use contraception; among those who used it, male condoms were most common but 11% were at risk of potential drug-drug interactions between oral contraception and enzyme-inducing antiepileptic drugs. Bhutanese WWE had a high rate of prenatal visits. Folic acid was prescribed in most pregnant WWE but the majority began supplementation in the second trimester. The number of pregnancies in WWE in Bhutan (2.3 per woman) was comparable to the number of children per women in Bhutan (2.3). Breastfeeding was practiced almost universally. Points of intervention may include pre-conception initiation of folic acid, optimization of dosing of AEDs with contraceptives, guidelines for peripartum seizure treatment, and establishment of a prospective registry for WWE and their offspring.

Areca catechu (palm tree) nut chewing and seizures: An observational study

OBJECTIVE

The objective of this study was to report the impact of chronic abuse of Areca catechu nut wrapped in leaf (also known as doma, quid, paan), the fourth most commonly abused psychoactive substance worldwide, on the frequency of seizures among people with epilepsy.

METHODS

People with clinically diagnosed epilepsy (>14years old) residing in the Kingdom of Bhutan were surveyed for self-reported Areca catechu use, demographic variables, epilepsy characteristics, and seizure frequency. The relationship between seizure frequency in the prior month and chewing Areca catechu, adjusted for various confounders, was analyzed using multivariable regression models.

RESULTS

There were 152 people with epilepsy, including 50 chewers (33%) and 102 (67%) nonchewers. The median duration of chewing A. catechu was 62months (25th, 75th percentiles: 24, 120months). Chewers consumed an average of three nuts daily. There was no significant difference between chewers and nonchewers in the mean age, proportion of male vs. female, age at first epileptic seizure, or number of antiepileptic drugs presently taken; chewers were more likely to be rural dwellers (p=0.042). After adjustment for all of the above variables, on average, chewers had 58.7% fewer [95%CI: (-79.4, -17.0)] seizures in the prior month, equating to 2.1 fewer [95% CI: (-3.9, -0.3)] seizures.

CONCLUSIONS

Our observational study suggests that the social custom of chewing Areca catechu nut is associated with reduced seizure frequency among people with epilepsy. This association may be due to its natural stimulant properties, a novel antiepileptic property of the nut, or has another, yet unknown explanation.

Yield of Brain MRI in Clinically Diagnosed Epilepsy in the Kingdom of Bhutan: A Prospective Study

BACKGROUND

People with epilepsy (PWE) in low- and middle-income countries may not access the health resources that are considered optimal for epilepsy diagnosis. The diagnostic yield of magnetic resonance imaging (MRI) has not been well studied in these settings.

OBJECTIVES

To report the diagnostic yield of brain MRI and identify clinical associations of abnormal MRI findings among PWE in a neurocysticercosis-endemic, resource-limited setting and to identify the proportion and putative structural brain causes of drug-resistant epilepsy.

METHODS

PWE were prospectively enrolled at the Jigme Dorji Wangchuck National Referral Hospital in Bhutan (2014-2015). Each participant completed clinical questionnaires and a 1.5-Tesla brain MRI. Each MRI was reviewed by at least 1 radiologist and neurologist in Bhutan and the United States. A working definition of drug-resistant epilepsy for resource-limited settings was given as (a) seizures for >1 year, (b) at least 1 seizure in the prior year, and (c) presently taking 2 or more antiepileptic drugs (AEDs). Logistic regression models were constructed to test the cross-sectional association of an abnormal brain MRI with clinical variables.

FINDINGS

A total of 217 participants (125 [57%] female; 54 [25%] < 18 years old; 199 [92%] taking AEDs; 154 [71%] with a seizure in the prior year) were enrolled. There was a high prevalence of abnormal brain MRIs (176/217, 81%). Mesial temporal sclerosis was the most common finding (n = 115, 53%, including 24 children), exceeding the number of PWE with neurocysticercosis (n = 26, 12%, including 1 child) and congenital/perinatal abnormalities (n = 29, 14%, including 14 children). The number of AEDs (odds ratio = .59, P = .03) and duration of epilepsy (odds ratio = 1.11, P = .02) were significantly associated with an abnormal MRI. Seizure in the prior month was associated with the presence of mesial temporal sclerosis (odds ratio = .47, P = .01). A total of 25 (12%) participants met our definition of drug-resistant epilepsy, with mesial temporal sclerosis (n = 10), congenital malformations (n = 5), and neurocysticercosis (n = 4) being the more common findings.

CONCLUSIONS

The prevalence of abnormalities on brain MRI for PWE in resource-limited settings is high as a result of a diffuse range of etiologies, most commonly mesial temporal sclerosis. Drug-resistant epilepsy accounted for 12% of the referral population in a conservative estimation.
