RESUMO

BACKGROUND AND PURPOSE: In Rwanda, epilepsy prevalence ranges between 29‰ and 49‰. Many women living with epilepsy (WwE) are of childbearing age. Epilepsy characteristics and management, contraception, pregnancy, puerperium and stigma in WwE presenting at the neurology clinic of Ndera, Rwanda, were investigated. METHODS: This prospective cross-sectional study investigated demographics, epilepsy characteristics, treatment, contraception, folic acid use, pregnancy, puerperium and stigma in WwE aged ≥18 years. Subgroups were analysed by status of any pregnancy and time of epilepsy diagnosis relative to pregnancy, with significant differences expected. RESULTS: During December 2020 and January 2021, a hundred WwE were enrolled (range 18-67 years). Fifty-two women had never been pregnant, 39 women had epilepsy onset before pregnancy and nine were diagnosed after pregnancy. No significant differences in age, marital status or occupation were observed. Contraception was used by 27%, of whom 50% were taking enzyme-inducing anti-epileptic medication. Valproate was used by 46% of WwE of reproductive age. Thirty-nine women with epilepsy onset before pregnancy reported 91 pregnancies, with 14% spontaneous abortions. None used folic acid before conception, and 59% only during pregnancy. Five of 78 newborns were preterm. No offspring had major congenital malformations. Nearly 25% of WwE were not compliant with their anti-epileptic medication schedule during pregnancy or breastfeeding. Internalized stigma was observed in more than 60%. Up to 25% had been discriminated against at school or work. CONCLUSION: A comprehensive strategy considering the reproductive health and societal challenges of WwE is needed to drive optimal epilepsy management, reproductive health outcomes and societal inclusion.

RESUMO

OBJECTIVES: Up to 85% of people living with epilepsy (PwE) reside in low-and middle-income countries. In sub-Saharan Africa, the lifetime prevalence of epilepsy is 16 per 1000 persons. In Northern rural Rwanda, a 47.7 per 1000 prevalence has been reported. As variations in prevalence across geographical areas have been observed, we studied the prevalence in Southern rural Rwanda using the same robust methodology as applied in the North. METHODS: We conducted a three-stage, cross-sectional, door-to-door survey in two rural villages in Southern Rwanda from June 2022 to April 2023. First, trained enumerators administered the validated Limoges questionnaire for epilepsy screening. Second, neurologists examined the persons who had screened positively to confirm the epilepsy diagnosis. Third, cases with an inconclusive assessment were separately reexamined by two neurologists to reevaluate the diagnosis. RESULTS: Enumerators screened 1745 persons (54.4% female, mean age: 24 ± 19.3 years), of whom 304 (17.4%) screened positive. Epilepsy diagnosis was confirmed in 133 (52.6% female, mean age: 30 ± 18.2 years) and active epilepsy in 130 persons. Lifetime epilepsy prevalence was 76.2 per 1000 (95% CI: 64.2-89.7‰). The highest age-specific rate occurred in the 29-49 age group. No gender-specific differences were noted. In 22.6% of the PwE, only non-convulsive seizures occurred. The treatment gap was 92.2%, including a diagnosis gap of 79.4%. CONCLUSION: We demonstrated a very high epilepsy prevalence in Southern rural Rwanda, with over 20% of cases having only non-convulsive seizures, which are often underdiagnosed in rural Africa. In line with previous Rwandan reports, we reiterate the high burden of the disease in the country. Geographic variation in prevalence throughout Africa may result from differences in risk and aetiological factors. Case-control studies are underway to understand such differences and propose adapted health policies for epilepsy prevention.

RESUMO

Objective: Up to one in four patients living with epilepsy (PwE) mentions financial constraints as a reason for loss to follow-up at the Ndera tertiary neuropsychiatry hospital. Therefore, we evaluated the annual direct medical cost (DMC) and direct non-medical cost (DnMC) of epilepsy and calculated costs assuming different follow-up frequency. Materials and Methods: DMC data were obtained from a descriptive retrospective study of medical records, pharmacy dispensation and hospital logs of PwE, following their initial consultation in 2018 and who adhered to the normal clinical practice of monthly consultations for one year. DnMC data were collected through structured interviews of PwE in a cross-sectional cohort in August 2020. DnMC included biomedical care costs (eg, transportation, hospitality) and non-biomedical costs (traditional healer visits). We report weighted means for total costs, health insurance costs, and out-of-pocket costs (OoP). Results: Mean annual total cost was 389.4 US$, of which 226.2 US$ was covered by the Rwandan Health Insurance co-payment for DMC and 163.2 US$ was OoP paid by patients. Mean weighted annual DMC (n = 55) was 248.9 US$. Mean weighted annual DMC for medical consultations and antiseizure medication accounted for 30.7 US$ and 161.7 US$, respectively. Based on structured interviews (n = 69), mean weighted annual DnMC for biomedical care was 73.0 US$. Mean DnMC for traditional healer care was 67.6 US$. Weighted annual total OoP was 163.2 US$ or 20% of the GDP per capita. OoP consisted of 14% DMC co-payment, 45% biomedical DnMC, and 41% traditional healer DnMC. Conclusion: Epilepsy-related costs at a tertiary center are an important economic burden for PwE and Rwandan Health Insurance. Biomedical and traditional healer DnMC constitute 86% of total OoP. Future prospective studies should evaluate outcomes and costs of reduced visit frequency, indirect costs, and costs of comorbidities.

RESUMO

INTRODUCTION: Depression is the most common psychiatric comorbidity for persons living with epilepsy. In Rwanda, the prevalence of epilepsy and depression are high, with 4,9% and 13.0% respectively. This prospective interventional study aimed to determine the prevalence and incidence of depression and the outcome of persons living with epilepsy (PwE) with depression attending the outpatient neurology department of a tertiary center. METHODS: Persons living with epilepsy enrolled between February and June 2018 in a screening cohort with a 12-month follow-up. At every 3-month study visit, PwE were screened for depression using the Patient Health Questionnaire (PHQ-9) questionnaire. Any positively screened subject was administered the Hamilton Depression Rating Scale (HDRS) to confirm the diagnosis and severity of depression. Subjects with moderate to severe depression (MSD), were started on treatment and were followed for another year. We describe the prevalence and incidence of depression, baseline characteristics, epilepsy and depression outcomes, and changes in PGI-C. RESULTS: Of 572 PwE enrolled, 46 were diagnosed with MSD in a twelve-month period, resulting in an incidence of MSD of 32.7/1000 patient-years. The prevalence of any depression and MSD was 14.2% and 4.7%, respectively. Longer epilepsy duration and seizure status at baseline were associated with MSD. Significant improvements in PGI-C and seizure frequency were observed after treatment optimization. CONCLUSION: The use of PHQ-9 and HDRS proved successful in identifying depression in PwE. Combined treatment of epilepsy and depression resulted in improved outcomes, warranting the implementation of depression screening every six months in daily neurology practice.

RESUMO

BACKGROUND: Patient satisfaction is an important outcome measure of health service and is one of the main reasons for the gradual deterioration of doctor-patient relationships in China. This study used the standardized patient (SP) method to explore patient satisfaction and its health provider-related determinants among primary health facilities in rural China. METHODS: The dataset comprised 1138 clinic cases in 728 rural primary health facilities in 31 counties, spread across four provinces. Information regarding the consultation interaction between the unannounced SPs and primary physicians was recorded. Patient satisfaction was gathered from the feedback of SPs after the visit. RESULTS: The overall average score of SP satisfaction with rural primary health facilities was only 13.65 (SD = 3.22) out of 20. The SP scores were found to be consistent with those of real patients. After controlling variances in patient population via the SP method, the regression analysis demonstrated that health provider-related factors, such as physician-level characteristics, consultation process, affordability, and convenience, have a significant correlation with patient satisfaction among primary physicians. Among factors relating to physician-level characteristics, affordability, convenience and the consultation process of the visit, the quality of the consultation process (e.g., consultation time, proactively providing necessary instructions and other crucial information) were found to be the prominent determinants. CONCLUSIONS: This study revealed the need to improve patient satisfaction in primary health facilities in rural China. To solve this issue, we recommend that policies to increase medical service quality be implemented in rural primary healthcare systems.

RESUMO

Poor knowledge, scarce resources, and lack of or misaligned incentives have been widely documented as drivers of the irrational use of medicine (IUM), which significantly challenges the efficiency of health systems across the globe. However, there is limited understanding of the influence of each factor on IUM. We used detailed data on provider treatment of presumptive asthma cases in rural China to assess the contributions of provider knowledge, resource constraints, and provider behavior on IUM. This study enrolled 370 village providers from southwest China. All providers responded to a clinical vignette to test their knowledge of how to treat presumptive asthma. Resource constraints ("capacity") were defined as the availability of the prescribed medicines in vignette. To measure provider behavior ("performance"), a subset of providers (104 of 370) were randomly selected to receive unannounced visits by standardized patients (SPs) who performed of presumptive asthma symptoms described in the vignette. We found that, 54% (201/370) of providers provided the vignette-based patients with prescriptions. Moreover, 67% (70/104) provided prescriptions for the SPs. For the vignette, only 10% of the providers prescribed the correct medicines; 38% prescribed only unnecessary medicines (and did not provide correct medicine); 65% prescribed antibiotics (although antibiotics were not required); and 55% prescribed polypharmacy prescriptions (that is, they prescribed five or more different types of drugs). For the SP visits, the numbers were 12%, 51%, 63%, and 0%, respectively. The lower number of medicines in the SP visits was due, in part, to the injections' not being allowed based on ethical considerations (in response to the vignette, however, 65% of providers prescribed injections). The difference between provider knowledge and capacity is insignificant, while a significant large gap exists between provider performance and knowledge/capacity (for 11 of 17 indicators). Our analysis indicated that capacity constraints play a minor role in driving IUM compared to provider performance in the treatment of asthma cases in rural China. If similar findings hold for other disease cases, this suggests that policies to reduce the IUM in rural China have largely been unsuccessful, and alternatives for improving aligning provider incentives with appropriate drug use should be explored.

RESUMO

INTRODUCTION: Engagement and training of community health workers (CHWs) have demonstrated their value in different conditions. Despite repeat epilepsy trainings of CHWs in Northern Rwanda, the treatment gap remained high. We hypothesized that effectiveness of CHWs on mobilization of patients living with epilepsy (PwE) could be improved using a validated tool for epilepsy screening. METHODS: CHWs associated with health centers (HCs) of Gataraga, Kimonyi and Karwasa attended a 1-day training on epilepsy and Limoges epilepsy screening questionnaire (Kinyarwanda version). Thereafter, CHWs screened households in their villages for persons with one or more positive answer. CHWs then accompanied positively screened persons to a consultation for clinical evaluation and diagnosis by neurologists, and demographic data were collected. CHW variables were collected retrospectively. RESULTS: A total of 1308 persons were screened positive by 281 CHWs. Clinical diagnosis of epilepsy was confirmed in 589 and in 93 additional unscreened PwE, presenting voluntarily at the consultation. Pre-intervention number of 48 PwE increased to 682 after, a 14.2-fold increase. The overall treatment gap amounted to 93.0%. The age distribution of male PwE preponderance at younger age inverted to females at older age. CHW characteristics showed non-significant differences within and across HCs. Logistic regression did not relate CHW age, gender, and experience to screening results. DISCUSSION: Equipping CHWs with a validated screening tool was effective in identifying and mobilizing PwE in a short time frame and offers opportunity for future scaling. Nonetheless, barriers to sustainability of care will need to be addressed before.

RESUMO

Objectives: To close the epilepsy treatment gap and reduce related stigma, eradication of misconceptions is importantIn 2014, Community Health Workers (CHWs) from Musanze (Northern Rwanda) were trained on different aspects of epilepsy. This study compared knowledge, attitude and practices (KAPs) towards epilepsy of trained CHWs 3 years after training, to untrained CHWs from Rwamagana (Eastern Rwanda). Methods: An epilepsy KAP questionnaire was administered to 96 trained and 103 untrained CHWs. Demographic and intergroup KAP differences were analysed by response frequencies. A multivariate analyses was performed based on desired and undesired response categories. Results: Epilepsy awareness was high in both groups, with better knowledge levels in trained CHWs. Negative attitudes were lowest in trained CHWs, yet 17% still reported misconceptions. Multivariate analysis demonstrated the impact of the training, irrespective of age, gender and educational level. Knowing someone with epilepsy significantly induced more desired attitudes. Conclusion: Despite demographic differences between trained and untrained CHWs, a single epilepsy training resulted in significant improvement of desired KAPs after 3 years. Nation-wide CHW training programs with focus on training-resistant items, e.g., attitudes, are recommended.

RESUMO

INTRODUCTION: In sub-Saharan Africa (SSA), the prevalence of lifetime epilepsy varies widely between subregions and is higher in rural compared to urban regions. Observed versus expected numbers of patients with epilepsy (PwE) in the northern province of Rwanda did not match the prevalence of 49‰ reported in 2005 in Rwanda. We report a confirmatory prevalence study focused on gender-specific observations. METHODS: A cross-sectional door-to-door approach was used in three rural villages. First, epilepsy screening using the Kinyarwanda version of the Limoges questionnaire was performed. Second, confirmation of epilepsy diagnosis was completed by trained physicians. RESULTS: In total, 2681 persons (56.14% female) were screened. Of 168 positively screened, 128 persons were diagnosed with epilepsy confirming the prevalence of lifetime epilepsy of 47.7‰ (CI 39.8-56.8). The diagnosis gap was 62.5% with 80 newly diagnosed. The overall female:male ratio was 1.61:1.00. A male preponderance below 9 years of age inverted to a female preponderance above 20 years of age. Female PwE had an older age at first seizure, reported different reasons for not seeking care, and differed from male PwE in possible etiology. For previously diagnosed PwE, the treatment gap was more than 77%. CONCLUSION: A high prevalence in rural areas was confirmed, with an observed female/male ratio among the highest of published door-to-door surveys in SSA. Gender differences in associated co-morbidities and age at first seizure warrant future research of underlying etiologies and possible survival bias. A better understanding and focus on gender-associated care-seeking patterns, education, and specific needs are recommended.

RESUMO

BACKGROUND: Although the progress in global health initiatives has improved the availability of primary health care (PHC), unqualified healthcare remains a serious challenge in low- and middle-income countries, where PHC is often underutilized. This study examines factors associated with patients' healthcare-seeking behaviors in rural Chin-seeking healthcare at village-level PHC providers, at higher-level health facilities, self-medicating, and refraining from seeking medical help. We focus on provider-side factors, including (1) the unobservable quality indicator, (2) the observable quality indicator, and (3) the observable signal indicator. METHODS: We analyzed 1578 episodes of healthcare-seeking behaviors of patients with diarrhea or cough/runny nose symptom from surveys conducted in July 2017 and January 2018 in 114 villages of the Yunnan province. We investigated the correlation between quality-related factors with patients' healthcare-seeking behaviors by multinomial logit regression. RESULTS: We found that rural patients were insensitive to the unobservable quality of healthcare providers, as measured by standardized clinical vignettes, which might be attributable to the credence nature of PHC. The observable quality indicator, whether the clinician has received full-time junior college formal medical education, was associated with patients' healthcare choices. Patients, however, were more likely to select healthcare based on the observable signal indicator, which was measured by the availability of medicines. Additionally, the observable signal indicator had no significant association with two quality indicators. Notably, socioeconomically-disadvantaged patients relied more on the village-level PHC, which emphasized the role of PHC in promoting the welfare of rural populations. CONCLUSIONS: Our study found an inconsistency between objective quality of healthcare provided by providers and subjective quality perceived by patients. Patients could not identify the actual quality of PHC precisely, while they were more likely to make decisions based on the observable signal indicator. Therefore, the quality of PHC should be more observable to patients. This study not only supplements the literature on healthcare-seeking choices by examining four types of behaviors simultaneously but also clarifies rural patients' perceptions of the quality of PHC for policy decision-making on increasing the utilization of PHC and improving the medical welfare of the vulnerable.

RESUMO

OBJECTIVE: Epilepsy is one of the most prevalent, treatable neurological diseases globally. In sub-Saharan Africa, people with epilepsy (PWE) frequently seek treatment from traditional or pastoral healers, who are more accessible than biomedical care providers. This often contributes to the substantial time delay in obtaining adequate biomedical care for these patients. In Uganda, the few biomedical providers who can treat epilepsy cannot meet the great need for epilepsy care. Additionally, patients are often hesitant to seek biomedical care, often preferring the easily accessible and trusted sociocultural treatment options. This study sought to elucidate the barriers to biomedical care for PWE as well as identify potential solutions to overcome these barriers from various stakeholder perspectives. METHODS: This study used qualitative research methods. Semistructured interviews and focus group discussions were conducted with four major stakeholder groups: PWE or family members of PWE, neurologists and psychiatrists, traditional healers, and pastoral healers. All interviews and focus group discussions that were in English were audio recorded and transcribed verbatim. Those that were not in English were translated live and audio recorded. A translator later translated the non-English portion of audio recording to ensure proper interpretation. Two independent coders coded the dataset and conducted an inter-rater reliability (IRR) assessment to ensure reliable coding of the data. Thematic analysis was then performed to discern themes from the data and compare nuances between each of the study design groups. RESULTS: Participants discussed several different causes of epilepsy ranging from spiritual to biological causes, often incorporating elements of both. Commonly endorsed spiritual causes of epilepsy included witchcraft and ancestral spirits. Commonly endorsed biological causes included genetics, fever, malaria, and brain injury. For patients and families, beliefs about the cause of epilepsy often played a role in whom they chose to seek treatment from. Three major barriers to biomedical care were discussed: practical barriers, medical infrastructure barriers, and barriers related to stigma. Practical barriers related to issues such as transportation, cost of medical care, and distance to the nearest healthcare facility. Under medical infrastructure, drug stock-outs and lack of access to antiepileptic drugs (AEDs) were the most consistent problems stated among patients. Stigma was heavily discussed and brought up by nearly every participant. Additionally, three significant solutions to improving epilepsy care in Uganda were highlighted by participants: collaboration among treatment providers, community sensitization efforts to address stigma, and building medical infrastructure. Within building infrastructure, all participant types, except traditional healers, proposed the development of an epilepsy clinic designed to specifically treat epilepsy. CONCLUSIONS: Based on these findings, there are four critical interventions that should be considered for improving epilepsy care in Uganda: the creation of dedicated epilepsy clinics, infrastructure strengthening to address medication stock-outs, community outreach programs for sensitization, and collaboration between biomedical providers and traditional healers.

RESUMO

In this summary paper, we review the body of research contained in this special issue, The Intersection of Culture, Resources, and Disease: Epilepsy Care in Uganda, and corollary recommendations for a way forward. We review key findings and conclusions for the studies, which tell a story of culture and care-seeking through discussions and data gleaned from a rich research landscape traversing community village dwellings, shared communal areas, churches, and urban hospitals. The voices and perspectives of over 16,000 study participants inclusive of people living with epilepsy, their neighbors and healthcare workers, traditional healers, and faith leaders are reported. From this, we synthesize findings and prioritize a set of recommendations to advance epilepsy care in Uganda. Progress will require infrastructure strengthening, multilevel educational investments, and an ambitious, extensive program of community sensitization. These proposed priorities and actions outline a way forward through formidable but surmountable challenges but require harmonized efforts by government and other relevant stakeholders, scholars, clinicians, and community leaders.

RESUMO

The expanding pandemic of coronavirus disease 2019 (COVID-19) requires the development of safe, efficacious and fast-acting vaccines. Several vaccine platforms are being leveraged for a rapid emergency response1. Here we describe the development of a candidate vaccine (YF-S0) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that uses live-attenuated yellow fever 17D (YF17D) vaccine as a vector to express a noncleavable prefusion form of the SARS-CoV-2 spike antigen. We assess vaccine safety, immunogenicity and efficacy in several animal models. YF-S0 has an excellent safety profile and induces high levels of SARS-CoV-2 neutralizing antibodies in hamsters (Mesocricetus auratus), mice (Mus musculus) and cynomolgus macaques (Macaca fascicularis), and-concomitantly-protective immunity against yellow fever virus. Humoral immunity is complemented by a cellular immune response with favourable T helper 1 polarization, as profiled in mice. In a hamster model2 and in macaques, YF-S0 prevents infection with SARS-CoV-2. Moreover, a single dose conferred protection from lung disease in most of the vaccinated hamsters within as little as 10 days. Taken together, the quality of the immune responses triggered and the rapid kinetics by which protective immunity can be attained after a single dose warrant further development of this potent SARS-CoV-2 vaccine candidate.

RESUMO

OBJECTIVE: Epilepsy is the most common chronic neurological disorder in the world and imposes a large economic burden on global healthcare systems, especially in low-income settings and rural areas as is found in sub-Saharan Africa (SSA). Despite the high epilepsy prevalence, there are no systematic descriptions of healthcare provider (HCP) perceptions and needs in managing people with epilepsy (PWE) in Uganda. Identifying these perceptions and needs is crucial for understanding community priorities, thereby enhancing the development of culturally sensitive communications, interventions, and research approaches. METHODS: In this qualitative study, we used semistructured interview guides to conduct focus group discussions that explored the perspectives of 32 providers of epilepsy care from health facilities around Mbarara, Uganda. Our sample included nonspecialized general physicians (n = 3), medical residents (n = 8), medical clinical officers (n = 3), psychiatric clinical nurses (n = 6), medical nurses and nursing assistants (n = 9), and other providers (n = 3), who were loosely grouped into discussion groups based on level or type of training. Self-assessed proficiency ratings were also administered to gain a better understanding of participants' confidence in their training, preparedness, and capabilities regarding epilepsy care. Thematic analysis of the focus group transcripts was conducted to ascertain commonly occurring themes about perceptions and challenges in epilepsy care. RESULTS: Our analyses identified nine major themes that dominated the perspectives of the study participants: care management, medications, diagnostics, HCP training, human resources, location, patient education, social support, and community knowledge and beliefs. Proficiency ratings prioritized areas of confidence as knowledge related to referrals, psychosocial impacts, and seizure neurophysiology. Areas of need were revealed as knowledge of diagnostic tools and antiepileptic drug (AED) regimens. CONCLUSIONS: Our findings delineate the perspectives of providers caring for PWE, with consistent recognition of challenges centering around resource augmentation, infrastructure strengthening, and education. Participants emphasized the urgent need to augment these resources to address limitations in medication types and access, trained human resources, and diagnostic tools. They overwhelmingly recognized the need for infrastructure strengthening to address human, diagnostic, medicinal, and capital resource limitations that place undue burden on patients with epilepsy and physicians. Providers indicated a clear desire to learn more about different diagnostic tools and medical management practices, potentially through continuing education, specialized training, or more intentional in-school diagnostic preparation. They also advocated for the powerful influence of patient and family education and clearly articulated the need for community sensitization and support.

RESUMO

OBJECTIVE: Epilepsy is a global public health concern, with the majority of cases occurring in lower- and middle-income countries where the treatment gap remains formidable. In this study, we simultaneously explore how beliefs about epilepsy causation, perceived barriers to care, seizure disorder characteristics, and demographics influence the initial choice of healthcare for epilepsy and its impact on attaining biomedical care (BMC). METHODS: This study utilized the baseline sample (n = 626) from a prospective cohort study of people with epilepsy (PWE) attending three public hospitals in Uganda (Mulago National Referral Hospital, Butabika National Referral Mental Hospital, and Mbarara Regional Referral Hospital) for epilepsy care. Patient and household demographics, clinical seizure disorder characteristics, and sociocultural questionnaires were administered. Logistic regression and principal component analyses (PCA) were conducted to examine associations with the choice of primary seizure treatment. RESULTS: The sample was 49% female, and 24% lived in rural settings. A biomedical health facility was the first point of care for 355 (56.7%) participants, while 229 (36.6%) first sought care from a traditional healer and 42 (6.7%) from a pastoral healer. Preliminary inspection of candidate predictors using relaxed criteria for significance (p < 0.20) identified several factors potentially associated with a greater odds of seeking BMC first. Demographic predictors included older caredriver (decision-maker for the participant) age (odds ratio [OR]: 1.01, 95% confidence interval [CI]: [0.99, 1.02], p-value: 0.09), greater caredriver education level (OR = 1.21, 95% CI: [1.07, 1.37], p-value = 0.003), and lower ratio of sick to healthy family members (OR = 0.77 [0.56, 1.05], P = 0.097). For clinical predictors, none of the proposed predictors associated significantly with seeking BMC first. Self-report causation predictors associated with a greater odds of seeking BMC first included higher belief in biological causes of epilepsy (OR = 1.31 [0.92, 1.88], P = 0.133) and lower belief in socio-spiritual causes of epilepsy (OR = 0.68 [0.56, 0.84], P < 0.001). In the multivariate model, only higher caredriver education (OR = 1.19 [1.04, 1.36], P = 0.009) and lower belief in socio-spiritual causes of epilepsy (OR = 0.69 [0.56, 0.86], P < 0.01) remained as predictors of seeking BMC first. Additionally, PCA revealed a pattern which included high income with low beliefs in nonbiological causes of epilepsy as being associated with seeking BMC first (OR = 1.32 [1.12, 1.55], p = 0.001). Despite reaching some form of care faster, individuals seeking care from traditional or pastoral healers experienced a significant delay to eventual BMC (P < 0.001), with an average delay of more than two years (traditional healer: 2.53 years [1.98, 3.24]; pastoral care: 2.18 [1.21, 3.91]). CONCLUSIONS: Coupled with low economic and educational status, belief in spiritual causation of epilepsy is a dominant determinant of opting for traditional or pastoral healing over BMC, regardless of concurrent belief in biological etiologies. There is a prolonged delay to eventual BMC for PWE who begin their treatment seeking with nonallopathic providers, and although nonallopathic healers provide PWE with benefits not provided by BMC, this notable delay likely prevents earlier administration of evidence-based care with known efficacy. Based on these findings, initiatives to increase public awareness of neurobiological causes of epilepsy and effectiveness of biomedical drug treatments may be effective in preventing delays to care, as would programs designed to facilitate cooperation and referral among traditional, faith-based, and biomedical providers.

RESUMO

Chronic diseases can be controlled through effective self-management. The purpose of this study is to explore the regularity of clinical visits and medication adherence of patients with hypertension or diabetes (PWHD), and its association with the first experience with care and individual factors in rural Southwestern China. This cross-sectional study was carried out in Yunnan province in 2018 and recruited 292 PWHD and 122 village clinics from 122 villages in 10 counties. Participants were interviewed using a structured questionnaire. Results show around 39% of hypertensive and 25% of diabetic patients neither visited physicians nor took medicine regularly during the preceding three months of the interview date. The regression results further indicated that individual characteristics of the PWHD, including patient age, health status, and economic level, as well as their first experience with care, were significantly associated with their regular healthcare behavior. In addition to providing medical services, on average each sample village clinic, with around two physicians, simultaneously managed 180 hypertensive and 45 diabetic patients. This study revealed the need for further reforms in terms of improving self-management and thus recommends an increase in the quantity and the quality of human resources in the primary healthcare realm in rural China.

RESUMO

INTRODUCTION: Mortality in persons living with epilepsy (PwE) is 1.6-9.3-fold higher than in the general population. Mortality from definite/probable Sudden Unexpected Death in EPilepsy (SUDEP) is estimated at 1.2 per 1000 person-years. We report mortality and SUDEP rate in a cohort of Rwandan PwE. METHODS: PwE presenting for a first visit at the Ndera epilepsy center between January and June 2016 were followed-up prospectively. For PwE who did not attend their follow-up visit, home visits were organized. Deaths were assessed using World Health Organization Verbal Autopsy Standards age-specific questionnaires. RESULTS: Of 235 PwE enrolled, home visits were organized for 81 (34.4%) PwE who did not return for their follow-up consultation. Seven fatalities (mortality 16.7/1000 patient-years [CI 6.7-34.3]) were recorded (aged 2-80 years). Four had an identified cause. Three were classified as probable SUDEP, resulting in a probable SUDEP rate of 7.1/1000 patient-years (CI 1.47-20.86). Probable SUDEP occurred in PwE (age: 2, 21, 34 years) showing no symptoms of illness while receiving antiepileptic treatment; in two cases, death occurred during sleep. CONCLUSION: Although autopsies were absent, the high mortality and probable SUDEP rates warrant future studies to establish causes of epilepsy-related deaths in Rwanda and sub-Saharan Africa.

RESUMO

Introduction: In Rwanda, major depressive disorder affects 11.9% of the population and up to 35% of genocide survivors. Mental health services remain underutilized due to stigma and lack of awareness. Increasing the ability and capacity to diagnose and treat mental disorders is considered important to close this gap. We describe the translation, validity, and reliability assessment of the Hamilton Depression Rating Scale (HDRS) as a diagnostic tool for moderate to severe depression in Rwanda. Methods: The HDRS-21 was translated by a multi-group taskforce. We validated the translation against expert assessment in a comparative study on a sample of patients living with depression and of healthy volunteers. Psychometric properties, namely internal structure, reliability, and external validity were assessed using confirmatory factor analysis, three reliability calculations, and correlation analysis, respectively. Maximized Youden's index was used for determining diagnostic cut-off. Results: The translated version demonstrated a kappa of 0.93. We enrolled 105 healthy volunteers and 105 patients with confirmed mild to severe depression. In the confirmatory factor analysis, HDRS had good factor loadings of 0.32-0.80. Reliability coefficients above 0.92 indicated strong internal consistency. External validity was shown by good sensitivity (0.95) and specificity (0.94) to differentiate depression from absence of depression. At a cut-off point of 17 for the diagnosis of depression, sensitivity and specificity were both 0.95 relative to gold standard. Conclusion: The validated HDRS in Kinyarwanda with diagnostic cut-off provides mental healthcare staff with an accurate tool to diagnose moderate to severe depression, enabling closure of the diagnosis and treatment gap.
