Cost-effectiveness of mass drug administration for control of scabies in Ethiopia: a decision-analytic model.

Background: The strategies to control scabies in highly endemic populations include individual case/household management and mass drug administration (MDA). We used a decision-analytic model to compare ivermectin-based MDA and individual case/household management (referred to as "usual care") for control of scabies in Ethiopia at different prevalence thresholds for commencing MDA. Methods: A decision-analytic model was based on a repeated population survey conducted in Northern Ethiopia in 2018-2020, which aimed to evaluate the secondary impact of single-dose ivermectin MDA for the control of onchocerciasis on scabies prevalence. The model estimates the number of scabies cases and costs of two treatment strategies (MDA and usual care) based on their effectiveness, population size, scabies prevalence, compliance with MDA, medication cost, and other parameters. Results: In the base-case analysis with a population of 100,000 and scabies prevalence of 15%, the MDA strategy was both more effective and less costly than usual care. The probability of MDA being cost-effective at the current cost-effectiveness threshold (equivalent to the cost of usual care) was 85%. One-way sensitivity analyses showed that the MDA strategy remained dominant (less costly and more effective) in 22 out of 26 scenarios. MDA was not cost-effective at scabies prevalence <10%, MDA effectiveness <85% and population size <5,000. An increase in the cost of ivermectin from 0 (donated) to 0.54 US$/dose resulted in a decrease in the probability of MDA being cost-effective from 85% to 17%. At 0.25 US$/dose, the MDA strategy was no longer cost-effective. Conclusions: The model provides robust estimates of the costs and outcomes of MDA and usual care and can be used by decision-makers for planning and implementing scabies control programmes. Results of our analysis suggest that single-dose ivermectin MDA is cost-effective in scabies control and can be initiated at a scabies prevalence >10%.

Distributed impact of severe mental health conditions in rural Ethiopia, a qualitative study.

AIM: To explore the distributed impact of severe mental health conditions (SMHCs) among people with lived experience of SMHCs, their family members, and community members. METHODS: We conducted in-depth interviews with family key informants of people with SMHCs (n = 32), people with SMHCs (schizophrenia, bipolar disorder, and major depression) (n = 10), and community members (n = 6) in rural Ethiopia. The study was nested within a long-standing population-based cohort of people with SMHCs. Interviews were conducted in Amharic and were audiotaped. We conducted a thematic analysis. RESULTS: We identified four themes: stress and physical tolls, lost expectations, social disruption, and economic threat. Family members reported stress and hopelessness; some also tried to harm themselves. Family members reported that their relationships with each other and with the wider community were disrupted significantly. Spouses and children did not get the support they needed, leading to unmet expectations: being left alone to care for children, unable to go to school or dropping out early. The study participants with SMHCs also spoke about the impacts of their illness on other family members and the community which appeared to be a source of shame and self-isolation. Both the family and the community respondents reported the economic effect of the illness which sometimes led to selling assets, debt, unemployment, forced migration, and food insecurity. Community members emphasised the economic burden and danger related to the aggressive behavior of the person with SMHCs, while the person with the illness and their family members blamed the community for the stigma and discrimination they experienced. CONCLUSION: SMHCs have profound consequences for the person with the illness, their family members, and the community. Future interventions for SMHCs should consider household-level interventions to address economic and care needs and mitigate the intergenerational impact. The community should be considered as a resource as well as a target for intervention.

A blended genome and exome sequencing method captures genetic variation in an unbiased, high-quality, and cost-effective manner.

We deployed the Blended Genome Exome (BGE), a DNA library blending approach that generates low pass whole genome (1-4× mean depth) and deep whole exome (30-40× mean depth) data in a single sequencing run. This technology is cost-effective, empowers most genomic discoveries possible with deep whole genome sequencing, and provides an unbiased method to capture the diversity of common SNP variation across the globe. To evaluate this new technology at scale, we applied BGE to sequence >53,000 samples from the Populations Underrepresented in Mental Illness Associations Studies (PUMAS) Project, which included participants across African, African American, and Latin American populations. We evaluated the accuracy of BGE imputed genotypes against raw genotype calls from the Illumina Global Screening Array. All PUMAS cohorts had R 2 concordance ≥95% among SNPs with MAF≥1%, and never fell below ≥90% R 2 for SNPs with MAF<1%. Furthermore, concordance rates among local ancestries within two recently admixed cohorts were consistent among SNPs with MAF≥1%, with only minor deviations in SNPs with MAF<1%. We also benchmarked the discovery capacity of BGE to access protein-coding copy number variants (CNVs) against deep whole genome data, finding that deletions and duplications spanning at least 3 exons had a positive predicted value of ~90%. Our results demonstrate BGE scalability and efficacy in capturing SNPs, indels, and CNVs in the human genome at 28% of the cost of deep whole-genome sequencing. BGE is poised to enhance access to genomic testing and empower genomic discoveries, particularly in underrepresented populations.

Quality of life among adults with scabies: A community-based cross-sectional study in north-western Ethiopia.

INTRODUCTION: Scabies undermines quality of life through its highly disturbing disease symptoms, by distorting self-perception, and secondary to social stigma. Knowledge of its effect on quality of life in general and on specific aspects of day-to-day life is key to addressing the health needs of individual patients and to evaluating gains from community-based disease control interventions. OBJECTIVES: To measure the effect of scabies on the quality of life of people with the infestation. METHODS: A community-based cross-sectional study was conducted in a scabies outbreak-affected district in north-western Ethiopia. The study involved 381 households and 86 adults with scabies. We used the ten-item Cardiff Dermatology Life Quality Index (DLQI) tool to collect data. Cronbach's alpha value was used to determine the internal consistency of the Amharic version of the scale. Overall and Dermatology Life Quality (DLQ) domain specific mean scores were calculated. The association between sociodemographic characteristics and scabies-related life quality impairment was tested using Kruskal-Wallis test. RESULTS: Scabies moderately affected the quality of life of adults with scabies. The overall mean DLQI (mDLQI) score was 9.2 (SD = 7.6). 'Symptoms and feelings' and 'daily activity' DLQ domains had the highest mDLQI scores (3.5, SD = 1.9 and 2.2, SD = 2.5, respectively). 'Leisure activities' was the least affected domain 0.8 (SD = 1.1). In terms of severity, scabies had moderate or severe effect on DLQ of 54.7% of the participants and extremely severe effect was reported among 27% of the participants. However, no association was observed between sociodemographic characteristics and quality of life impairment. CONCLUSION: Quality of life was moderately impaired among people affected by scabies. Refocusing attention on management of disease symptoms, using standard scabies treatment, and providing psychosocial support to improve self-perception of people affected with scabies may help reduce quality of life impairment.

The unmet mental health needs of adolescents with HIV in eastern Tanzania: Experiences of healthcare providers, adolescents, and caregivers.

Adolescents with Human Immunodeficiency Virus (HIV) are at greater risk for mental health problems than their HIV-negative counterparts. However, there is a dearth of evidence on the need for mental health services, including interventions for depression in adolescents with HIV (AWHIV), in most low- and middle-income countries (LMICs). This study's objective was to explore the unmet mental health needs of AWHIV to inform the development and implementation of a psychological intervention for depression in AWHIV in Dar es Salaam, Tanzania. A descriptive phenomenological qualitative study design was used. Consultative meetings with providers and 45 in-depth interviews were conducted with AWHIV, caregivers, and healthcare providers (HCPs) to explore their experiences and unmet mental health needs for AWHIV. Data from the consultative meetings were triangulated to validate the obtained information with those from interviews. Data were organized and managed with the aid of NVIvo-11. The thematic analysis framework guided data analysis. Five major themes emerged: Experience of complex symptoms, unmet need for services, impact of the unmet needs, ways utilized in managing symptoms, and preferred intervention. Complex depressive symptoms expressed as physical, behavioral, or somatic complaints adversely affected ART adherence and academic performance, led to substance use, and compromised overall quality of life in AWHIV. HIV-Care and Treatment Centers (HIV-CTCs) did not conduct formal mental health screenings. Instead, caregivers and HCPs addressed the symptoms of mental health problems with death threats and corporal punishments. No evidence-based depression interventions existed in HIV-CTCs for observed symptoms. This study reports on unmet mental health needs with a clear impact on the lives of AWHIV, which may have significant implications for treatment adherence. There is an urgent need to develop and implement effective and scalable interventions to address these mental health needs.

Barriers and enablers to improving integrated primary healthcare for non-communicable diseases and mental health conditions in Ethiopia: a mixed methods study.

BACKGROUND: The Ethiopian Primary Healthcare Clinical Guidelines (EPHCG) seek to improve quality of primary health care, while also expanding access to care for people with Non-Communicable Diseases and Mental Health Conditions (NCDs/MHCs). The aim of this study was to identify barriers and enablers to implementation of the EPHCG with a particular focus on NCDs/MHCs. METHODS: A mixed-methods convergent-parallel design was employed after EPHCG implementation in 18 health facilities in southern Ethiopia. Semi-structured interviews were conducted with 10 primary healthcare clinicians and one healthcare administrator. Organisational Readiness for Implementing Change (ORIC) questionnaire was self-completed by 124 health workers and analysed using Kruskal Wallis ranked test to investigate median score differences. Qualitative data were mapped to the Consolidated Framework for Implementation Science (CFIR) and the Theoretical Domains Framework (TDF). Expert Recommendations for Implementing Change (ERIC) were employed to select implementation strategies to address barriers. RESULTS: Four domains were identified: EPHCG training and implementation, awareness and meeting patient needs (demand side), resource constraints/barriers (supply side) and care pathway bottlenecks. The innovative facility-based training to implement EPHCG had a mixed response, especially in busy facilities where teams reported struggling to find protected time to meet. Key barriers to implementation of EPHCG were non-availability of resources (CFIR inner setting), such as laboratory reagents and medications that undermined efforts to follow guideline-based care, the way care was structured and lack of familiarity with providing care for people with NCDs-MHCs. Substantial barriers arose because of socio-economic problems that were interlinked with health but not addressable within the health system (CFIR outer setting). Other factors influencing effective implementation of EPHCG (TDF) included low population awareness about NCDs/MHCs and unaffordable diagnostic and treatment services (TDF). Implementation strategies were identified. ORIC findings indicated high scores of organisational readiness to implement the desired change with likely social desirability bias. CONCLUSION: Although perceived as necessary, practical implementation of EPHCG was constrained by challenges across domains of internal/external determinants. This was especially marked in relation to expansion of care responsibilities to include NCDs/MHCs. Attention to social determinants of health outcomes, community engagement and awareness-raising are needed to maximize population impact.

Studying the context of psychoses to improve outcomes in Ethiopia (SCOPE): Protocol paper.

BACKGROUND: Global evidence on psychosis is dominated by studies conducted in Western, high-income countries. The objectives of the Study of Context Of Psychoses to improve outcomes in Ethiopia (SCOPE) are (1) to generate rigorous evidence of psychosis experience, epidemiology and impacts in Ethiopia that will illuminate aetiological understanding and (2) inform development and testing of interventions for earlier identification and improved first contact care that are scalable, inclusive of difficult-to-reach populations and optimise recovery. METHODS: The setting is sub-cities of Addis Ababa and rural districts in south-central Ethiopia covering 1.1 million people and including rural, urban and homeless populations. SCOPE comprises (1) formative work to understand care pathways and community resources (resource mapping); examine family context and communication (ethnography); develop valid measures of family communication and personal recovery; and establish platforms for community engagement and involvement of people with lived experience; (2a) a population-based incidence study, (2b) a case-control study and (2c) a cohort study with 12 months follow-up involving 440 people with psychosis (390 rural/Addis Ababa; 50 who are homeless), 390 relatives and 390 controls. We will test hypotheses about incidence rates in rural vs. urban populations and men vs. women; potential aetiological role of khat (a commonly chewed plant with amphetamine-like properties) and traumatic exposures in psychosis; determine profiles of needs at first contact and predictors of outcome; (3) participatory workshops to develop programme theory and inform co-development of interventions, and (4) evaluation of the impact of early identification strategies on engagement with care (interrupted time series study). Findings will inform development of (5) a protocol for (5a) a feasibility cluster randomised controlled trial of interventions for people with recent-onset psychosis in rural settings and (5b) two uncontrolled pilot studies to test acceptability, feasibility of co-developed interventions in urban and homeless populations.

Perceived barriers and opportunities for implementing an integrated psychological intervention for depression in adolescents living with HIV in Tanzania.

BACKGROUND: Adolescents living with Human Immunodeficiency Virus (HIV) have an increased risk of depression, negatively affecting their adherence to antiretroviral therapy (ART) and treatment outcomes. Integrating mental health care in HIV care and treatment settings improves comprehensive care. However, integration remains challenging in Tanzania, like in other high-burden and low-resource settings. The overall objective of this work is to inform the development of a psychological intervention for depression in adolescents living with HIV (ALWHIV). We describe perceived barriers and opportunities for implementing an integrated, evidence-based psychological intervention to manage adolescent depression in HIV care and treatment centers (HIV-CTC) from the perspectives of adolescents, caregivers, and healthcare providers (HCPs) in Dar es Salaam, Tanzania. METHODS: To inform intervention development and implementation, this study utilized a qualitative design through a phenomenological approach informed by the Consolidated Framework for Implementation Research (CFIR) to explore implementation barriers and facilitators in ALWHIV, HCPs, and caregivers. Forty-five in-depth interviews were conducted in three HIV-CTCs in Kinondoni Dar es Salaam. Audio records were transcribed verbatim and analyzed deductively through NVIVO software. RESULTS: Barriers to implementing an integrated psychological intervention to address depression in ALWHIV included (A) poor mental health awareness among caregivers, adolescents, HCPs, and policy-makers, (B) high level of stigma against mental health care, (C) poor communication between adolescents and HCPs concerning mental health care, (D) lack of contextualized intervention of proven effectiveness and guidelines of mental health care, and (E) inadequate mental health care supportive supervision and mentorship. Facilitators for implementation included supportive infrastructure, positive pressure from HIV implementing partners, tension for change, and participant's perception of the advantage of a psychological intervention as compared to just usual HIV care and treatment counseling. CONCLUSION: Despite several modifiable barriers to implementing a psychological intervention in HIV CTC, there were encouraging facilitators and opportunities for implementing an integrated, evidence-based psychological intervention to address depression in ALWHIV in Kinondoni Dar es Salaam, Tanzania.

The role of a community conversation intervention in reducing stigma related to lower limb lymphoedema in Northern Ethiopia.

BACKGROUND: Stigma related to lower-limb lymphoedema poses a major psychosocial burden to affected persons and acts as a barrier to them accessing morbidity management and disability prevention (MMDP) services. Community Conversation (CC), which actively engages community members and disseminates health information amongst them, is believed to break the vicious cycle of stigma by enhancing disease-related health literacy at the community level. METHODS: A quasi-experimental study was conducted in Northern Ethiopia to assess the role of the CC intervention in reducing stigma. In two control districts, a comprehensive and holistic MMDP care package was implemented that included physical health, mental health and psychosocial interventions, whilst in the intervention district the CC intervention was added to the MMDP care package. A total of 289 persons affected by lymphoedema and 1659 community members without lymphoedema were included in the study. RESULTS: Over the course of the intervention, in all sites, community members' knowledge about the causes of lymphoedema increased, and perceived social distance and stigmatizing attitudes towards people with lymphoedema decreased in the community, whilst experienced and internalized stigma decreased amongst affected persons. There were no significant changes for perceived social support. However, the changes were greater in the control sites overall, i.e. those districts in which the holistic care package was implemented without CC. CONCLUSION: The findings suggest that the CC intervention provides no additional stigma reduction when used alongside a holistic MMDP care package. Provision of comprehensive and holistic MMDP services may be adequate and appropriate to tackle stigma related to lower-limb lymphoedema in a resource-constrained setting like Ethiopia.

Developing interventions to improve detection of depression in primary healthcare settings in rural Ethiopia.

BACKGROUND: The poor detection of depression in primary healthcare (PHC) in low- and middle-income countries continues to threaten the plan to scale up mental healthcare coverage. AIMS: To describe the process followed to develop an intervention package to improve detection of depression in PHC settings in rural Ethiopia. METHOD: The study was conducted in Sodo, a rural district in south Ethiopia. The Medical Research Council's framework for the development of complex interventions was followed. Qualitative interviews, observations of provider-patient communication, intervention development workshops and pre-testing of the screening component of the intervention were conducted to develop the intervention. RESULTS: A multicomponent intervention package was developed, which included (a) manual-based training of PHC workers for 10 days, adapted from the World Health Organization's Mental Health Gap Action Programme Intervention Guide, with emphasis on depression, locally identified depressive symptoms, communication skills, training by people with lived experience and active learning methods; (b) screening for culturally salient manifestations of depression, using a four-item tool; (c) raising awareness among people attending out-patient clinics about depression, using information leaflets and health education; and (d) system-level interventions, such as supportive supervision, use of posters at health facilities and a decision support mobile app. CONCLUSIONS: This contextualised, multicomponent intervention package may lead to meaningful impact on the detection of depression in PHC in rural Ethiopia and similar settings. The intervention will be pilot tested for feasibility, acceptability and effectiveness before its wider implementation.

No secondary impact of ivermectin mass drug administration for onchocerciasis elimination on the prevalence of scabies in northwestern Ethiopia.

BACKGROUND: Mass drug administration (MDA) is among the five major strategies that are currently in use to control, eliminate or eradicate Neglected Tropical Diseases (NTDs). Optimising MDA to control multiple NTDs maximises impact. The objective of this study is to estimate the secondary impact of ivermectin MDA for onchocerciasis on the prevalence of scabies. METHODS: This quasi-experimental study was conducted in Ayu Guagusa district, northwestern Ethiopia. Scabies prevalence was estimated in surveys before the MDA, at 6 and 12 months afterwards. The sample size was 1437 people from a panel of 381 randomly selected study households. Multistage sampling was employed in randomly selecting six kebeles (the lowest administrative unit) with respective gotes (small villages) and households. All members of the selected households were invited to participate in the study and participants who were available in all three surveys formed a cohort. RESULTS: Scabies prevalence was similar prior to the MDA (13.4%, 95% CI 11.7 to 15.2%) and 6 months after (11.7%, 95% CI 10.1 to 13.2%) but was substantially greater at 12 months (22.1%, 95% CI 20.1 to 24.1%). The 6-month incidence and disappearance rates were 10.8% (95% CI 8.8 to 13.2%) and 82.6% (95% CI 75.0 to 88.6%), respectively. CONCLUSIONS: Ivermectin MDA for onchocerciasis was not observed to have a secondary impact on the prevalence of scabies over the follow-up period of 12 months.

Challenges for research uptake for health policymaking and practice in low- and middle-income countries: a scoping review.

BACKGROUND: An estimated 85% of research resources are wasted worldwide, while there is growing demand for context-based evidence-informed health policymaking. In low- and middle-income countries (LMICs), research uptake for health policymaking and practice is even lower, while little is known about the barriers to the translation of health evidence to policy and local implementation. We aimed to compile the current evidence on barriers to uptake of research in health policy and practice in LMICs using scoping review. METHODS: The scoping review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses-extension for Scoping Reviews (PRISMA-ScR) and the Arksey and O'Malley framework. Both published evidence and grey literature on research uptake were systematically searched from major databases (PubMed, Cochrane Library, CINAHL (EBSCO), Global Health (Ovid)) and direct Google Scholar. Literature exploring barriers to uptake of research evidence in health policy and practice in LMICs were included and their key findings were synthesized using thematic areas to address the review question. RESULTS: A total of 4291 publications were retrieved in the initial search, of which 142 were included meeting the eligibility criteria. Overall, research uptake for policymaking and practice in LMICs was very low. The challenges to research uptake were related to lack of understanding of the local contexts, low political priority, poor stakeholder engagement and partnership, resource and capacity constraints, low system response for accountability and lack of communication and dissemination platforms. CONCLUSION: Important barriers to research uptake, mainly limited contextual understanding and low participation of key stakeholders and ownership, have been identified. Understanding the local research and policy context and participatory evidence production and dissemination may promote research uptake for policy and practice. Institutions that bridge the chasm between knowledge formation, evidence synthesis and translation may play critical role in the translation process.

Experience of traumatic events in people with severe mental illness in a low-income country: a qualitative study.

BACKGROUND: This study describes the trauma experiences of people with severe mental illness (SMI) in Ethiopia and presents a model of how SMI and trauma exposure interact to reduce functioning and quality of life in this setting. METHODS: A total of 53 participants living and working in a rural district in southern Ethiopia were interviewed: 18 people living with SMI, 21 caregivers, and 14 primary health care providers. RESULTS: Many participants reported that exposure to traumatic and stressful events led to SMI, exacerbated SMI symptoms, and increased caregiver stress and distress. In addition, SMI symptoms and caregiver desperation, stress or stigma were also reported to increase the possibility of trauma exposure. CONCLUSIONS: Results suggest it is incumbent upon health professionals and the broader health community to view trauma exposure (broadly defined) as a public health problem that affects all, particularly individuals with SMI.

Community-based rehabilitation intervention for people with schizophrenia in Ethiopia (RISE) cluster-randomised controlled trial: An exploratory analysis of impact on food insecurity, underweight, alcohol use disorder and depressive symptoms.

We evaluated the effectiveness of community-based rehabilitation (CBR) in reducing depressive symptoms, alcohol use disorder, food insecurity and underweight in people with schizophrenia. This cluster-randomised controlled trial was conducted in a rural district of Ethiopia. Fifty-four sub-districts were allocated in a 1:1 ratio to the facility-based care [FBC] plus CBR arm and the FBC alone arm. Lay workers delivered CBR over 12 months. We assessed food insecurity (self-reported hunger), underweight (BMI< 18.5 kg/m2), depressive symptoms (PHQ-9) and alcohol use disorder (AUDIT ≥ 8) at 6 and 12 months. Seventy-nine participants with schizophrenia in 24 sub-districts were assigned to CBR plus FBC and 87 participants in 24 sub-districts were assigned to FBC only. There was no evidence of an intervention effect on food insecurity (aOR 0.52, 95% CI 0.16-1.67; p = 0.27), underweight (aOR 0.44, 95% CI 0.17-1.12; p = 0.08), alcohol use disorder (aOR 0.82, 95% CI 0.24-2.74; p = 0.74) or depressive symptoms (adjusted mean difference - 0.06, 95% CI -1.35, 1.22; p = 0.92). Psychosocial interventions in low-resource settings should support access to treatment amongst people with schizophrenia, and further research should explore how impacts on economic, physical and mental health outcomes can be achieved.

Scabies in the Amhara region of northern Ethiopia: a cross-sectional study of prevalence, determinants, clinical presentation and community knowledge.

BACKGROUND: The WHO aims to prevent, eliminate or control neglected tropical diseases, including scabies, by 2030. However, limited epidemiological data presented a challenge to control efforts, especially in high burden countries. There was a major scabies outbreak in northern Ethiopia starting in 2015 and prevalence has since increased across much of the country. OBJECTIVE: To estimate scabies prevalence, identify its predictors, and assess community perception of, and knowledge about, the infestation. DESIGN: Population-based cross-sectional study. STUDY SETTING: Ayu Guagusa district, Amhara region, northern Ethiopia. PARTICIPANTS: 1437 people who were members of 381 randomly selected households participated in the study. Five trained mid-level health workers clinically diagnosed people with scabies. OUTCOME MEASURES: Clinically diagnosed scabies infestation. DATA ANALYSIS: Multi-level logistic regression models were fitted to adjust for individual and household-level confounding variables, and identify predictors of scabies infestation. RESULTS: Scabies prevalence was 13.4% (95% CI 11.8 to 15.5). Households of more than five people (adjusted OR (aOR)=3.5, 95% CI 1.2 to 10.2) were associated with increased odds of developing scabies, however, females had lower odds (aOR=0.5 95% CI 0.3 to 0.8). Scabietic lesions most frequently involved the trunk (62.0%), and vesicles were the most common types of lesions (67.7%). Two-thirds of adult study participants had heard about scabies and most obtained scabies related information from informal sources. Only 32% of cases sought care for scabies from any source. CONCLUSION: Scabies prevalence was high, signifying the need for community-based control interventions. Host density and sex were important predictors of scabies. Despite the favourable attitude toward the effectiveness of scabies treatment, healthcare seeking was low.

Burden of neglected tropical diseases and access to medicine and diagnostics in Ethiopia: a scoping review.

BACKGROUND: More than 1.7 billion people are affected by neglected tropical diseases (NTDs) worldwide. Forty percent of the NTD-affected people live in Africa with the poorest, most vulnerable, and hard to reach geographical areas. The NTDs cause significant social and economic burden and deepen marginalization and stigmatization. The World Health Organization's current roadmap for NTD aims to prevent, control, eliminate, or eradicate 20 tropical diseases. Ethiopia experiences a high burden of these diseases, but current access to diagnostics, medicine, and/or care has been little explored to inform the country's NTD strategic plan. The overall purpose of the scoping review was to map and characterize the burden of NTDs and challenges in access to diagnostics, medicine, and/or care in Ethiopia. METHODS: A systematic search of evidence was conducted in PubMed, Cochrane Library, and Google Scholar from January 2000 until May 2022, without restrictions of language or study design. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Review was followed for screening of studies. Key findings were extracted and narrated qualitatively. RESULTS: The search resulted in 4532 articles, of which 105 met the inclusion criteria and were included in the scoping review under three themes: burden of NTDs, access to diagnostics, medicine and/or care, and key barriers. Although gains have been made in the prevention and control of NTDs in Ethiopia, the burden remains high, and progress in access to diagnostics, medicine/drugs, and/or care is very slow. Poverty, poor quality of life, and underfunding of NTD programs decelerate the process of NTD elimination program in the country. CONCLUSIONS: The scoping review identified a considerable number of studies on the burden of NTDs in Ethiopia and strategies for diagnosis, treatment, and/or care; however, there is a paucity of evidence on the suitability and potential benefits of novel diagnostic technologies and medicines in the country. A regular review and analysis of such country-level evidence is important to inform the country NTDs roadmap and local implementation strategies.

Mobile Health-Supported Active Syndrome Surveillance for COVID-19 Early Case Finding in Addis Ababa, Ethiopia: Comparative Study.

BACKGROUND: Since most people in low-income countries do not have access to reliable laboratory services, early diagnosis of life-threatening diseases like COVID-19 remains challenging. Facilitating real-time assessment of the health status in a given population, mobile health (mHealth)-supported syndrome surveillance might help identify disease conditions earlier and save lives cost-effectively. OBJECTIVE: This study aimed to evaluate the potential use of mHealth-supported active syndrome surveillance for COVID-19 early case finding in Addis Ababa, Ethiopia. METHODS: A comparative cross-sectional study was conducted among adults randomly selected from the Ethio telecom list of mobile phone numbers. Participants underwent a comprehensive phone interview for COVID-19 syndromic assessments, and their symptoms were scored and interpreted based on national guidelines. Participants who exhibited COVID-19 syndromes were advised to have COVID-19 diagnostic testing at nearby health care facilities and seek treatment accordingly. Participants were asked about their test results, and these were cross-checked against the actual facility-based data. Estimates of COVID-19 detection by mHealth-supported syndromic assessments and facility-based tests were compared using Cohen Kappa (κ), the receiver operating characteristic curve, sensitivity, and specificity analysis. RESULTS: A total of 2741 adults (n=1476, 53.8% men and n=1265, 46.2% women) were interviewed through the mHealth platform during the period from December 2021 to February 2022. Among them, 1371 (50%) had COVID-19 symptoms at least once and underwent facility-based COVID-19 diagnostic testing as self-reported, with 884 (64.5%) confirmed cases recorded in facility-based registries. The syndrome assessment model had an optimal likelihood cut-off point sensitivity of 46% (95% CI 38.4-54.6) and specificity of 98% (95% CI 96.7-98.9). The area under the receiver operating characteristic curve was 0.87 (95% CI 0.83-0.91). The level of agreement between the mHealth-supported syndrome assessment and the COVID-19 test results was moderate (κ=0.54, 95% CI 0.46-0.60). CONCLUSIONS: In this study, the level of agreement between the mHealth-supported syndromic assessment and the actual laboratory-confirmed results for COVID-19 was found to be reasonable, at 89%. The mHealth-supported syndromic assessment of COVID-19 represents a potential alternative method to the standard laboratory-based confirmatory diagnosis, enabling the early detection of COVID-19 cases in hard-to-reach communities, and informing patients about self-care and disease management in a cost-effective manner. These findings can guide future research efforts in developing and integrating digital health into continuous active surveillance of emerging infectious diseases.

Mapping digital health ecosystems in Africa in the context of endemic infectious and non-communicable diseases.

Investments in digital health technologies such as artificial intelligence, wearable devices, and telemedicine may support Africa achieve United Nations (UN) Sustainable Development Goal for Health by 2030. We aimed to characterize and map digital health ecosystems of all 54 countries in Africa in the context of endemic infectious and non-communicable diseases (ID and NCD). We performed a cross-national ecological analysis of digital health ecosystems using 20-year data from the World Bank, UN Economic Commission for Africa, World Health Organization, and Joint UN Programme on HIV/AIDS. Spearman's rank correlation coefficients were used to characterize ecological correlations between exposure (technology characteristics) and outcome (IDs and NCDs incidence/mortality) variables. Weighted linear combination model was used as the decision rule, combining disease burden, technology access, and economy, to explain, rank, and map digital health ecosystems of a given country. The perspective of our analysis was to support government decision-making. The 20-year trend showed that technology characteristics have been steadily growing in Africa, including internet access, mobile cellular and fixed broadband subscriptions, high-technology manufacturing, GDP per capita, and adult literacy, while many countries have been overwhelmed by a double burden of IDs and NCDs. Inverse correlations exist between technology characteristics and ID burdens, such as fixed broadband subscription and incidence of tuberculosis and malaria, or GDP per capita and incidence of tuberculosis and malaria. Based on our models, countries that should prioritize digital health investments were South Africa, Nigeria, and Tanzania for HIV; Nigeria, South Africa, and Democratic Republic of the Congo (DROC) for tuberculosis; DROC, Nigeria, and Uganda for malaria; and Egypt, Nigeria, and Ethiopia for endemic NCDs including diabetes, cardiovascular disease, respiratory diseases, and malignancies. Countries such as Kenya, Ethiopia, Zambia, Zimbabwe, Angola, and Mozambique were also highly affected by endemic IDs. By mapping digital health ecosystems in Africa, this study provides strategic guidance about where governments should prioritize digital health technology investments that require preliminary analysis of country-specific contexts to bring about sustainable health and economic returns. Building digital infrastructure should be a key part of economic development programs in countries with high disease burdens to ensure more equitable health outcomes. Though infrastructure developments alongside digital health technologies are the responsibility of governments, global health initiatives can cultivate digital health interventions substantially by bridging knowledge and investment gaps, both through technology transfer for local production and negotiation of prices for large-scale deployment of the most impactful digital health technologies.

Safety of equine tetanus antitoxin for prophylactic use in Ethiopia: a retrospective multi-center study.

BACKGROUND: Tetanus remains a severe life-threatening infectious disease and neurological disorder in many parts of the world, where immunization programs are suboptimal. Any human injury or trauma has the possibility of getting infected with Clostridium tetani which is the sole causative bacterium of tetanus. Evidence is available that TAT may cause anaphylaxis and late serum sickness, while there has been no study conducted in Ethiopia. The Ethiopian Ministry of Health standard treatment guideline recommends tetanus prophylaxis for all tetanus-prone wounds. This study aimed to evaluate the safety of TAT administration in adults exposed to tetanus-prone wounds in Ethiopia. METHODS: The target product of this study was the equine tetanus antitoxin developed and manufactured by the ViNS Bioproducts Limited, India (Code: 130202084, A.W.No: 15/AAW/PI/02.00, DT: 25.04.2016). The product is delivered with the dose of 1000/1500 IU intramuscularly or subcutaneously to individuals at risk of tetanus infection for prophylactic purposes. The study was carried out in 11 healthcare facilities in Addis Ababa, Ethiopia, that had a relatively high clients load for tetanus-prone wounds. Medical records of patients with tetanus-prone wounds who received the equine TAT were reviewed retrospectively for any adverse events following immunization according to the World Health Organization (WHO) definition for adverse events following immunization (AEFI). RESULTS: There were more than 20,000 patients treated for trauma in the facilities from 2015 to 2019. Upon revision of available registration books, we identified 6000 charts to be eligible for the study, of which 1213 charts that had complete and reliable data on the AEFI profile of the TAT were included in the final analysis. The median age of the study participants was 26 years (IQR = 11 years, age range: 18-91 years) and 78% (949) were male. The tetanus-prone wounds resulted mainly from stab (44%, 535) and blunt force (30%, 362), and the most common sites of wounds were hand (22%, 270) and head (21%, 253). The most and least frequently occurring types of wounds were open wounds (77%, 930) and organ system injury (0.003%, 4), respectively. The mean time of presenting at health facilities from the onset of trauma was 2.96 h. Of the total 1231 participants, one male participant who presented within 3 h after experiencing a wound on his nose at the workplace had a severe local reaction immediately after injection of the TAT. No AEFI was recorded for the other participants. CONCLUSIONS: The adverse event following immunization of the equine tetanus antitoxin produced by the ViNS Bioproducts Limited was very rare. A regular review of the product's safety performance and systematic collection and analysis of adverse event reports are important to ensure the safety of the product.

Interventions to improve the detection of depression in primary healthcare: systematic review.

BACKGROUND: Several studies have been conducted on the effect of interventions on the detection of depression in primary healthcare (PHC). Systematic reviews have also been done on the effectiveness of separate interventions. However, systematic reviews are not done on the comparative effectiveness of several interventions. This study, therefore, aimed at synthesizing the global evidence on the effectiveness of interventions to improve the detection of depression in PHC. METHODS: We searched PubMed, Embase, PsycINFO, Web of Science, Cochrane Database of Systematic Reviews, Global Index Medicus, African Index Medicus, and African Journals Online, from the inception of the databases to until the 4th week of April 2020. We also searched references of the included articles. We included randomized trials, cluster randomized trials, or quasi-experimental studies, which evaluated the effectiveness of an intervention to improve detection of depression in the PHC setting. Two of the review authors independently extracted data from the included studies. The methodological quality of the included studies was assessed using the Assessment Tool for Quantitative Studies developed by the Effective Public Health Practice Project. The protocol for the review was registered on PROSPERO (CRD42020166291). RESULTS: Of 23,305 records identified, we included 58 articles in the review. Diverse types of interventions were evaluated to improve clinician diagnosis of depression in the PHC setting. Interventions related to implementation of guidelines, screening with feedback, educational interventions which incorporated active learning and clinical practice, and disclosure of screening results were found to be mostly effective. Interventions which combined education, screening, and feedback were particularly more effective. Most of the included studies were weak or moderate in their methodological quality. CONCLUSIONS: Our review indicates that implementation of a single type of intervention does not improve the detection of depression in PHC. Combining aspects of each type of intervention which are more effective may be useful. Education and training interventions which include more simulation and role playing are found to be effective over time. Most of the studies conducted in the area are from high-income countries and are weak in their methodological quality. There is need to conduct more number of studies in low-income settings.
