RESUMO

OBJECTIVE: The objective of this study is to estimate the prevalence of epilepsy with Tonic-Clonic (TC) seizures in rural areas of the Bolivian Gran Chaco and to evaluate the usefulness of telemedicine in this context. METHODS: The study was carried out in the Isozo Area, southern-eastern Bolivia. Twenty-five rural communities with a population of 8258 inhabitants were included in the survey. Trained community-health workers administered a validated single screening question to the householders (stage I). A second face-to-face questionnaire was administered to each positive subject (stage II). At stage II subjects were also screened using the smartphone app "Epilepsy Diagnosis Aid". Subjects screened positive at stage II underwent a complete neurological examination to confirm the diagnosis (stage III). Due to the COVID-19 lockdown, some subjects have been evaluated through a digital platform (Zoom®). RESULTS: One-thousand two-hundred and thirteen interviews were performed at stage I, corresponding to a total screened population of 6692 inhabitants. Thirty-eight screened positive were identified at stage I and II and of these, 28 people with epilepsy were identified, giving an overall prevalence of 4.2/1000 (95% CI 2.6-5.7). Prevalence rate steeply increased with age reaching a peak of 7.9/1000 in the population aged 20-29 years without significant differences between women and men. For almost 50% of the screened positive subjects, confirmation of epilepsy by a neurologist at stage III was achieved through simple videoconsultation. After a simultaneous awareness campaign, 22 self-reported PWE requested a consultation and, among them, 11 had a diagnosis of epilepsy confirmed. SIGNIFICANCE: This study shows a prevalence estimate close to those reported for LMIC. Simple videoconsultation and specific apps may be valuable tools in epidemiological research. Awareness campaigns are important allies for a full case identification, particularly in contexts where higher rates of stigma are recorded.

RESUMO

The Bolivian Chaco is a semiarid region with a low population density, situated in the southeast part of the Plurinational State of Bolivia. Here, despite the improvements of the last 15 years, poverty remains high in rural areas, where social vulnerability is widespread. The Guaraní ethnic group often lives in isolated communities with a low standard of hygiene and sanitation. This epidemiological scenario favors the spread of transmissible diseases, including several parasitic infections belonging to the neglected tropical diseases (NTDs) group. In this area, a long-standing research activity, built upon the synergism between local and foreign institutions, has been established since the late 1980s and helps to fill in the knowledge gap about the epidemiology dynamics of soil-transmitted helminths, vector-borne parasites, and other parasitic diseases. A 35-year history of cooperation programs in parasitology research has contributed to informing local health authorities of the NTD burden in the Bolivian Chaco and, ultimately, supports local healthcare providers in the management of parasitic diseases.

RESUMO

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 ±â€¯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.

RESUMO

INTRODUCTION: In low- and middle-income countries (LMIC), the diagnosis of epilepsy should be made by Non-Physician Health Workers (NPHW) who are widely available in these settings. Recently a smartphone app (Epilepsy Diagnosis Aid) has been developed and validated to be used by NPHW, in order to confirm the diagnosis of epilepsy. The aim of our study was to perform a validation of the app in two different contexts: a hospital-based setting of a high-income country (HIC) and a population-based setting of the rural communities of a LMIC. MATERIAL AND METHODS: For the hospital-based setting, the app was administered to a sample of patients with epilepsy (PWE) and to a sample of subjects affected by syncope attending the epilepsy center of the University of Catania. For the population-based setting, performed in the rural communities of the Gran Chaco region in Bolivia,the app was administered by NPHW to a sample of PWE previously identified. Sensitivity and specificity were calculated for the diagnosis of epilepsy. RESULTS: In the hospital-setting, the app was administered to 100 PWE and 20 syncopes. A probability score > 80 showed a sensitivity of 76% (95%CI 66.4-84) and a specificity of 100% (95%CI 83.2-100) for the diagnosis of epilepsy; higher values were found for active epilepsy with tonic-clonic seizures. In the rural-setting, the app was administered to 38 PWE, giving a sensitivity of 92.1% (95%CI 78.6-98.3). CONCLUSION: The app for epilepsy could represent a valuable instrument, which can be easily employed by trained NPHW to diagnose epilepsy in primary health-care settings of LMIC.

RESUMO

INTRODUCTION: In low- and middle-income countries (LMIC), epilepsy still represents a significant health challenge. In the Bolivian Chaco, we have previously found high levels of stigma towards people with epilepsy (PWE) especially expressed by high school students. In order to increase the knowledge about epilepsy, we have tested a comic book-based intervention on a sample of high school students. METHODS: The study has been conducted in the Bolivian Chaco region where two urban and two rural classrooms have been randomly selected. Students have been administered a knowledge, attitudes, and practices (KAP) questionnaire, and then they underwent a comic book-based educational program where they were randomly assigned either to an autonomous reading or a character interpretation methodology. The same KAP questionnaire has been administered after the teaching session and at a three months follow-up. Mean KAP scores at the baseline were compared with the after teaching and the three-month assessment. RESULTS: Eighty-three students with a mean age of 15.5 ±â€¯0.9 years, of whom 38 (45.8%) males, were recruited. After the comic book session, students improved in the global score (p < 0.001) and in the knowledge (p < 0.001), attitudes (p = 0.004), and practices (p < 0.001) subscores. Both the autonomous reading and the character interpretation groups significantly improved in the global score, but only the latter improved in all the subscores. At the three months follow-up, there were no differences in the global, knowledge, and attitudes subscores, compared with scores immediately after the intervention. CONCLUSION: Using a comic book to teach about epilepsy led to a significant improvement in the knowledge, attitudes, and practices about the disease in high school students of LMIC. This teaching strategy can be easily implemented in LMIC.

RESUMO

INTRODUCTION: Epilepsy represents around 0.7% of the overall global burden of diseases and is particularly prevalent and associated with significant disability in low- and middle-income countries (LMIC) in Latin American Countries (LAC). A community-based epilepsy awareness program was carried out by our group in the rural areas of the Chaco region, Plurinational state of Bolivia, to improve the knowledge about epilepsy, with a first part directed toward general practitioners and a second part toward nurses and community health workers (CHWs) of the rural communities with a positive outcome. The objective of the study was to assess the level of knowledge, attitudes, and practices toward epilepsy, the stigma related to epilepsy and the quality of life in people with epilepsy (PWE) before and after the interventional campaign directed toward representative members of the rural communities in the Chaco region in Bolivia. METHODS: The study was conducted in three areas of Bolivia. Key subjects from each community were randomly selected. Before and after the courses they answered a questionnaire to assess their knowledge, attitudes, beliefs, and practices about epilepsy, a validated Stigma Scale of Epilepsy (SSE) and Quality of Life in Epilepsy Inventory-10 (QOLIE-10). RESULTS: Two hundred sixteen subjects were involved in the program. Only 133 (61.6%) subjects completed the questionnaires a month after the educational program. A significant improvement was recorded in knowledge, attitudes, and practices toward epilepsy, and a significant reduction was found in the mean SSE total score (38.3 ±â€¯14.7 vs. 28.5 ±â€¯12.3; p < 0.01), reflecting a reduction of stigma levels. Regarding the quality of life, after the training, PWE stated to experience less depression, memory difficulties, work or social issues, and seizure worry. CONCLUSION: Our study confirms that continuous educational campaigns can lead to a significant change in the social perception and attitudes toward epilepsy.

RESUMO

INTRODUCTION: Epilepsy represents a major global healthcare issue, particularly in low- and middle-income countries (LMIC), where nonmedical health workers play a key role in providing care to people with epilepsy (PWE). Over the last 20 years, many projects have been carried out by our group in the Chaco region, Plurinational State of Bolivia, with the aim of enhancing knowledge about epilepsy. However, the level of knowledge of epilepsy that nonmedical health workers have reached has never been assessed until now. The main objective of our study was to assess the level of knowledge, attitudes, and practices (KAP) towards epilepsy among nonmedical health staff of the rural communities of the Chaco region in Bolivia. METHODS: The study was conducted in three departments of Bolivia. The nonmedical health personnel were invited to participate in a training program. They answered a validated questionnaire to evaluate their knowledge and attitudes towards epilepsy before and after the courses. RESULTS: One hundred nineteen subjects [42 men (36.2%); mean age 29.3 ±â€¯1.1 years] were interviewed among community health workers and nurses before the courses, demonstrating a very good level of knowledge regarding epilepsy and its causes. Only 55 health workers participated in the second training module, and their answer did not significantly differ from the baseline. CONCLUSION: Our study confirms the usefulness of continuous educational campaigns, especially directed to nonspecialist healthcare providers of rural communities of LMIC, as they may be the only persons responsible for providing healthcare to PWE in that setting. Moreover, the importance of the baseline assessment of KAP was highlighted in order to adapt the educational campaigns to the baseline level of knowledge found.

RESUMO

INTRODUCTION: Epilepsy represents a major health problem in low- and middle-income countries where treatment gap (TG) levels are high. The reduction of epilepsy TG in the rural area of the Chaco region, Plurinational State of Bolivia, has been the aim of many projects based on the reinforcement of the primary care setting. To plan educational campaigns directed to the healthcare professionals, it is necessary to establish their baseline knowledge level. The objective of our study was to assess the baseline level of knowledge, attitudes, and practices (KAP) towards epilepsy among general practitioners (GPs) of the rural communities of the Chaco region. METHODS: The study was conducted in three departments of Bolivia. All the GPs living in these areas were invited to participate in the study consisting of two training modules six months apart from each other, each with two-day duration. They answered a validated questionnaire to evaluate the KAP towards epilepsy before and after the courses. RESULTS: Fifty GPs [30 men (60%); mean age: 32.1±5.8years] participated in the first training course. After six months, 31 GPs (62%) [19 men (61.3%); mean age: 33±5.0years] participated in the second module. Before the training, the majority of GPs declared a low level of satisfaction about their epilepsy knowledge, which improved after the courses. A change in practices was recorded after the training, with an increased confidence to manage antiepileptic treatment. CONCLUSION: Our study showed the significant impact of specific training programs on epilepsy among GPs.

RESUMO

INTRODUCTION: Epilepsy is one of the most common neurological diseases in Latin American Countries (LAC) and epilepsy associated with convulsive seizures is the most frequent type. Therefore, the detection of convulsive seizures is a priority, but a validated Spanish-language screening tool to detect convulsive seizures is not available. We performed a field validation to evaluate the accuracy of a Spanish-language questionnaire to detect convulsive seizures in rural Bolivia using a three-stage design. The questionnaire was also administered face-to-face, using a two-stage design, to evaluate the difference in accuracy. METHODS: The study was carried out in the rural communities of the Gran Chaco region. The questionnaire consists of a single screening question directed toward the householders and a confirmatory section administered face-to-face to the index case. Positive subjects underwent a neurological examination to detect false positive and true positive subjects. To estimate the proportion of false negative, a random sample of about 20% of the screened negative underwent a neurological evaluation. RESULTS: 792 householders have been interviewed representing a population of 3,562 subjects (52.2% men; mean age 24.5 ± 19.7 years). We found a sensitivity of 76.3% (95% CI 59.8-88.6) with a specificity of 99.6% (95% CI 99.4-99.8). The two-stage design showed only a slightly higher sensitivity respect to the three-stage design. CONCLUSION: Our screening tool shows a good accuracy and can be easily used by trained health workers to quickly screen the population of the rural communities of LAC through the householders using a three-stage design.
