RESUMO
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.

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.

Bhutan has been witnessing a trend of increasing diabetes in recent years. The increase is attributed to a rise in risk factors such as overweight, high blood pressure, unhealthy diet and sedentary lifestyle among the population. To address the rising burden, the health-services response has been to establish diabetes clinics in all hospitals and grade one basic health units. People visiting the health centres who have high risk factors and symptoms for diabetes are screened using the World Health Organization cut-off level for blood glucose. They are then classified into prediabetes and diabetes. Accordingly, diet, medicine and physical activity are recommended as per their body mass index. To improve prevention and control of noncommunicable diseases, which include diabetes, the country piloted the WHO Package of Essential Noncommunicable (PEN) disease interventions for primary health care in low-resource settings in 2009, to promote early screening, treatment and follow-up, and adopted it in 2013. The WHO PEN has now been successfully integrated into the primary health-care system nationwide. It is planned that diabetes clinics will be upgraded to NCD clinics.
