Effect of nature on the mental health and well-being of children and adolescents: meta-review.

BACKGROUND: Urbanisation is taking place worldwide and rates of mental illness are rising. There has been increasing interest in 'nature' and how it may benefit mental health and well-being. AIMS: To understand how the literature defines nature; what the characteristics of the nature intervention are; what mental health and well-being outcomes are being measured; and what the evidence shows, in regard to how nature affects the mental health and well-being of children and adolescents. METHOD: A meta-review was conducted, searching three databases for relevant primary and secondary studies, using key search terms including 'nature' and 'mental health' and 'mental well-being'. Inclusion criteria included published English-language studies on the child and adolescent population. Authors identified the highest quality evidence from studies meeting the inclusion criteria. Data were extracted and analysed using descriptive content analysis. RESULTS: Sixteen systematic reviews, two scoping reviews and five good quality cohort studies were included. 'Nature' was conceptualised along a continuum (the 'nature research framework') into three categories: a human-designed environment with natural elements; a human-designed natural environment; and a natural environment. The nature 'intervention' falls into three areas (the 'nature intervention framework'): access, exposure and engagement with nature, with quantity and quality of nature relevant to all areas. Mental health and well-being outcomes fit along a continuum, with 'disorder' at one end and 'well-being' at the other. Nature appears to have a beneficial effect, but we cannot be certain of this. CONCLUSIONS: Nature appears to have a beneficial effect on mental health and well-being of children and adolescents. Evidence is lacking on clinical populations, ethnically diverse populations and populations in low- and middle-income countries. Our results should be interpreted considering the limitations of the included studies and confidence in findings.

Anatomy education in low-resourced countries: What are challenges and effective and affordable educational strategies? A qualitative study.

PURPOSE: With limited means, resource-deprived countries must find ways to organize education to meet standards. Few reports exist about anatomical education in LLMICs. This study explores how anatomy teaching is sustained in countries with few resources and which affordable educational strategies are applied to uphold quality. METHODS: A mixed-methods study with anatomy teachers from public medical schools in low or lower-middle income countries (LLMICs) in Africa, Asia, Europe, and Latin-American was performed through survey via email combined with semi-structured online interview with teachers, exploring survey results at a deeper level. RESULTS: LLMICs available to be surveyed, 13 and 8 were found to respond to a written survey and oral interview invitation, face significant teaching challenges, primarily due to lack of funds. These are faculty shortages (low salaries and high student-to-teacher ratio) and inadequate infrastructure (internet, electricity, poor classroom conditions). Solutions were associated with didactic strategies (social media, e-learning, image-based learning, applied anatomy), expanding teaching capacity with less qualified and part-time faculty, student-organized education, and self-financing (teaching resources subsidized by teachers and students). Which was triking was teacher commitment despite difficult circumstances. Teachers propose better faculty management, increased anatomy staff recruitment, and collaboration with other institutions. CONCLUSIONS: Anatomical education in LLMIC is forced to adapt to the socio-economic context, rather than to trends in medical education worldwide. These adaptations are supported mainly by the teachers 'commitment.'

Comparing the effectiveness and cost-effectiveness of alternative Type 2 Diabetes monitoring intervals in resource limited settings.

Type 2 Diabetes (T2D) represents a growing disease burden in South Africa. While glycated haemoglobin (HbA1c) testing is the gold standard for long-term blood glucose management, recommendations for HbA1c monitoring frequency are based on expert opinion. This study investigates the effectiveness and cost effectiveness of alternative HbA1c monitoring intervals in the management of T2D. A Markov model with three health states (HbA1c <7%, HbA1c ≥ 7%, Dead) was used to estimate lifetime costs and quality-adjusted-life-years (QALYs) of alternative HbA1c monitoring intervals among patients with T2D, using a provider's perspective and a 3% discount rate. HbA1c monitoring strategies (three-monthly, four-monthly, six-monthly, and annual tests) were evaluated with respect to the incremental cost-effectiveness ratio (ICER) assessing each comparator against a less costly, undominated alternative. The scope of costs included the direct medical costs of managing diabetes. Transition probabilities were obtained from routinely collected public sector HbA1c data, while health service utilization and health-related-quality-of-life (HRQoL) data were obtained from a local cluster randomized controlled trial. Other parameters were obtained from published studies. Robustness of findings was evaluated using one-way and probabilistic sensitivity analyses. A South African indicative cost-effectiveness threshold of USD2,665 was adopted. Annual and lifetime costs of managing diabetes increased with HbA1c monitoring, while increased monitoring provides higher QALYs and Life Years. For the overall cohort, the ICER for six-monthly vs annual monitoring was cost-effective (USD 2,322.37 per QALY gained), whereas the ICER of moving from six-monthly to three-monthly monitoring was not cost-effective(USD 6,437.79 per QALY gained). The ICER for four-monthly vs six-monthly monitoring was extended dominated. The sensitivity analysis showed that the ICERs were most sensitive to health service utilization rates. While the factors influencing glycaemic control are multifactorial, six-monthly monitoring is potentially cost-effective while more frequent monitoring could further improve patient HrQoL.

A comparison of factors influencing the safety of pedestrians accessing bus stops in countries of differing income levels.

Pedestrian fatalities comprise a quarter of all traffic deaths in Low-and-Middle-Income Countries (LMICs). The use of safer modes of transport such as buses can reduce road trauma as well as air pollution and traffic congestion. Although travelling by bus is safer than most other modes, accessing bus stops can be risky for pedestrians. This paper systematically reviews factors contributing to the safety of pedestrians near bus stops in countries of differing income levels. The review included forty-one studies from high (20), upper-middle (13) and lower-middle income countries (8) during the last two decades. The earliest research was conducted in high-income countries (HICs), but research has spread in the last decade. The factors influencing pedestrian safety fell into three groups: (a) characteristics of road users, (b) characteristics of bus stops and (c) characteristics of the road traffic environment. Pedestrians near bus stops are frequently exposed to a high risk of collisions and fatalities due to factors such as unsafe pedestrian behaviours (e.g., hurrying to cross the road), lack of bus stop amenities such as safe footpaths, high traffic speeds and traffic volumes, multiple lanes, and roadside hazards (e.g., parked cars obscuring pedestrians). Road crash statistics are commonly used to identify unsafe bus stops in HICs but the unavailability and unreliability of data have prevented more widespread use in LMICs. Future research is recommended to focus on surrogate safety measures to identify hazardous bus stops for pedestrians.

Contextual Barriers to Implementing Open-Source Electronic Health Record Systems for Low- and Lower-Middle-Income Countries: Scoping Review.

BACKGROUND: Low- and lower-middle-income countries account for a higher percentage of global epidemics and chronic diseases. In most low- and lower-middle-income countries, there is limited access to health care. The implementation of open-source electronic health records (EHRs) can be understood as a powerful enabler for low- and lower-middle-income countries because it can transform the way health care technology is delivered. Open-source EHRs can enhance health care delivery in low- and lower-middle-income countries by improving the collection, management, and analysis of health data needed to inform health care delivery, policy, and planning. While open-source EHR systems are cost-effective and adaptable, they have not proliferated rapidly in low- and lower-middle-income countries. Implementation barriers slow adoption, with existing research focusing predominantly on technical issues preventing successful implementation. OBJECTIVE: This interdisciplinary scoping review aims to provide an overview of contextual barriers affecting the adaptation and implementation of open-source EHR systems in low- and lower-middle-income countries and to identify areas for future research. METHODS: We conducted a scoping literature review following a systematic methodological framework. A total of 7 databases were selected from 3 disciplines: medicine and health sciences, computing, and social sciences. The findings were reported in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) checklist. The Mixed Methods Appraisal Tool and the Critical Appraisal Skills Programme checklists were used to assess the quality of relevant studies. Data were collated and summarized, and results were reported qualitatively, adopting a narrative synthesis approach. RESULTS: This review included 13 studies that examined open-source EHRs' adaptation and implementation in low- and lower-middle-income countries from 3 interrelated perspectives: socioenvironmental, technological, and organizational barriers. The studies identified key issues such as limited funding, sustainability, organizational and management challenges, infrastructure, data privacy and protection, and ownership. Data protection, confidentiality, ownership, and ethics emerged as important issues, often overshadowed by technical processes. CONCLUSIONS: While open-source EHRs have the potential to enhance health care delivery in low- and lower-middle-income-country settings, implementation is fraught with difficulty. This scoping review shows that depending on the adopted perspective to implementation, different implementation barriers come into view. A dominant focus on technology distracts from socioenvironmental and organizational barriers impacting the proliferation of open-source EHRs. The role of local implementing organizations in addressing implementation barriers in low- and lower-middle-income countries remains unclear. A holistic understanding of implementers' experiences of implementation processes is needed. This could help characterize and solve implementation problems, including those related to ethics and the management of data protection. Nevertheless, this scoping review provides a meaningful contribution to the global health informatics discipline.

Status of functional neurosurgery in lower middle-income countries (LMICs): A multinational cross sectional survey based analysis of exposure, utilization and perceived barriers.

INTRODUCTION: Functional Neurosurgery (FNS) is a non-invasive and highly efficacious neurosurgical subspecialty but lower middle-income countries (LMICs) are disadvantaged in terms of access and availability of FNS. Through this study we have tried to assess the availability, exposure, utilization, and perceived barriers to five major FNS modalities including deep brain stimulation (DBS), vagal nerve stimulation (VNS), stereotactic radiosurgery (SRS), MRI-guided focused ultrasound (MRgfUS) and percutaneous rhizotomy in LMICs. METHODOLOGY: We designed a survey using google forms while following the CHERRIES guidelines. Responses were collected from practicing neurosurgeons, neurosurgical fellows, and residents in LMICs. Statistical analysis was performed using SPSS software 26.0 RESULTS: A total of 100 responses were recorded of which 96 % were males. 68 % worked in an educational setup. Respondents had the most exposure to SRS (36 %) followed by DBS (28 %) while MRgFUS was the least exposed modality (4 %) (p<0.001). For all modalities except MRgFUS, majority of the respondents were 'Fairly confident' (p<0.001). No statistically significant association was observed in the availability of the modalities with the type of working setup. Majority of the respondents did not consider legal issues (p=0.003) and patient preferences (p=0.007) to be perceived barriers for any modality. Accessibility, affordability, Lack of training were not significant factors for any modality except DBS (52 %, p<0.001; 55 %, p<0.001 and 53 %, p=0.002 respectively) CONCLUSION: An integrated approach including international collaborations, traveling fellowships, novel policies must be adopted to enhance the reach of FNS to LMICs to share the extensive neurosurgical burden and to ease the neurosurgical decision making.

COVID-19 vaccination in low and middle-income countries: Creating a sustainable roadmap for promoting public health intervention.

The Coronavirus Disease 2019 (COVID-19) pandemic is a global public health threat ravaging the health systems. In low and middle-income countries (LMICs), COVID-19 and several other challenges concurrently worsen the health outcome indicators. Interestingly, vaccines have been identified as the most reliable and cost-effective public health intervention, and the governments in LMICs have instituted an array of plans to ensure every eligible person gets vaccinated. However, there is still considerable apathy around the use of the available COVID-19 vaccines in LMICs which is impeding the fight against the COVID-19 pandemic. In this paper, we explore the multiple interrelated factors behind low COVID-19 vaccination coverage in LMICs. It is therefore recommended that the governments in LMICs embrace multicomponent and wide-ranging strategies. This should involve utilising community-based approaches such as community pharmacy-led vaccination to promote community access to COVID-19 vaccines and to revive trust in national health authorities by offering population-specific, target-driven, transparent, and timely communication to the community who they serve about the safety and efficacy of the COVID-19 vaccine. Communication strategies should be tailored to reflect diverse political orientations as this can enhance vaccine acceptance. Additionally, local political parties and representative should be engaged in broad alliances to facilitate community mobilisation and support for vaccination campaigns. Also, relevant Nongovernmental Organisations and Community-based Organisations should institute programs at the grassroots that incorporate the gatekeepers to the community aimed at influencing population behaviour regarding COVID-19 vaccine hesitancy. Besides, the public health department in the ministry of health in LMICs should create more awareness, through social and mass media, particularly in the rural, semi-urban, and slum communities about the pivotal role of vaccination. Thus, we opined that these strategies will help LMICs achieve the COVID-19 vaccination target and further reposition the healthcare systems, and promote other public health interventions now and in the future.

Factors Associated With Major Lower Extremity Amputations in Diabetic Foot Infections at a County Hospital in Guatemala.

INTRODUCTION: Outcomes from diabetic foot infections (DFIs) at the major referral hospital (Hospital Nacional de San Benito) in El Petén, Guatemala have not been analyzed. We hypothesized that poor diabetic control might be associated with a high rate of major lower extremity amputations (mLEAs; above the ankle). METHODS: We performed a retrospective analysis at Hospital Nacional de San Benito between (8/14 and 6/23) in patients presenting with DFIs. Patients receiving mLEAs were compared with all others (AO = [trans-metatarsal amputations, toe amputations, incision and drainage, and antibiotic treatment]). Interviews surgeons were undertaken to ascertain reasons for index operation choice. Univariable and multivariable analyses were undertaken to determine factors associated with mLEAs. RESULTS: Of 110 patients with DFIs, there were 23 mLEAs (above the knee = 21, below the knee = 2). Age, duration with diabetes, and a prior ipsilateral minor amputation were associated with mLEAs. Multivariable analysis identified white blood cell count as significant for mLEA (odds ratio = 1.5 95% confidence interval [1.0 to 2.5]). Cited reasons for a high rate of above the knee amputation (AKAs) versus below the knee amputation were patient related (advanced disease, patient frailty, and poor compliance), systemic (lack of vascular equipment and knee immobilizer), and surgeon related. CONCLUSIONS: This cohort of patients presented with an average of 15 years with diabetes mellitus and poor adherence to diabetic treatment (40%). Many of these diabetic patients developed a DFI requiring mLEAs (21%), most of which were AKAs (91%). Efforts to minimize the number of AKA versus below the knee amputation require immediate attention. Programs to adhere to DM control and foot care in patients with DM are urgently needed.

Clinical features, biomarkers and diabetic ketoacidosis at diagnosis of type 1 diabetes among children and adolescents in Sana'a, Yemen.

INTRODUCTION: There is little published information on type 1 diabetes (T1D) in children in Yemen. We aimed to identify the clinical characteristics, biomarkers and diabetic ketoacidosis (DKA) at diagnosis of T1D among children and adolescents in a diabetes centre in Sana'a, Yemen. METHODS: A total of 485 children and adolescents aged ≤18 years diagnosed with T1D during the period 2010-2020 were included in the study. The variables investigated were demographic and clinical characteristics, biomarkers, subtypes of T1D, and the risk factors for severe DKA at diagnosis. RESULTS: At diagnosis, children aged <10 years compared with those aged ≥10 years had higher mean plasma glucose (p<0.001) and mean HbA1c (p=0.026), and lower mean C-peptide (pmol/L) (p=0.019), and a higher frequency of DKA at diagnosis than older children (p<0.001). A majority of the study population (383, 79%) presented in DKA . Children aged <10 years presenting with DKA had significantly longer median appraisal interval (p=0.009) and median total diagnosis interval (p=0.025), and significantly lower mean C-peptide (p=0.001) as compared with their peers without DKA. The prevalence of autoantibody-negative 'idiopathic' T1D was 36 (32%) of the total number tested for autoantibody and familial T1D 61 (12.6%) of all the study population. CONCLUSION: In Yemen children aged <10 years with new-onset T1D frequently faced the challenge of a delay in diagnosis and treatment initiation, with severe hyperglycaemia and a higher risk of DKA at diagnosis.

Impact of planned delivery mode on neonatal outcomes and costs in twin pregnancies in Kenya.

Background: Twin pregnancies are associated with higher risks of adverse neonatal outcomes compared to singleton pregnancies. The choice of delivery mode, when twin A presents cephalic, remains a subject of debate. In low- and middle-income countries, where healthcare resources are limited, the decision on the mode of delivery is even more critical. Objective: To evaluate the neonatal outcomes and the hospital costs of planned vaginal delivery compared to cesarean section (CS) in twin pregnancies with twin A presenting cephalic at Tenwek Hospital, Kenya. Study Design: This retrospective cohort study analyzed data from all twin deliveries at Tenwek Hospital, Kenya from, April 1, 2017, to March 30, 2023. Maternal data, mode of delivery, and neonatal data were collected from delivery logs, electronic health records, and neonatal records. Neonatal outcomes were a composite of either Appearance, Pulse, Grimace, Activity, and Respiration score less than seven at 5 minutes, neonatal intensive care unit admission, resuscitation, birth trauma, or neonatal complications, including death before discharge from the hospital. A logistic regression model was created to assess the impact of the planned mode of delivery on neonatal outcomes, controlling for antenatal care clinic visits, noncephalic presentation of twin B, and birth weight category. Results: The study included 177 twin deliveries: 129 (72.9%) were planned as vaginal deliveries and 48 (27.1%) were planned for CS. Among the planned vaginal deliveries, 66 (51.2%) experienced adverse outcomes, compared to 14 (29.2%) in the CS group (P=.009). Logistic regression showed that the odds of adverse outcomes were 0.35 times lower in the CS group compared to the planned vaginal delivery group (95% CI: 0.15-0.83; P=.017). The average total hospital costs for planned vaginal delivery were 104,608 Kenya Shillings (standard deviation 111,761) compared to 100,708 Kenya Shillings (standard deviation 75,468) for CS (P=.82). Conclusion: Planned cesarean deliveries in twin pregnancies with twin A presenting cephalic at Tenwek Hospital were associated with fewer adverse neonatal outcomes compared to planned vaginal deliveries. There was no significant difference in hospital costs. These findings raise the question of the safest mode of delivery for patients in a resource-constrained setting.

Exploring help-seeking pathways and disparities in substance use disorder care in India: A multicenter cross-sectional study.

Background: Substance use disorders (SUDs) are among the leading causes of morbidity in the population. In low- and medium-income countries like India, there is a wide treatment gap for SUD. A multicentric study on the care pathways for SUD in India can help to understand service provision, service utilization, and challenges to improve existing SUD care in India. Aim: We aimed to map pathways to care in SUD. We compared the clinical and demographic characteristics of patients who first consulted specialized services versus other medical services. Methods: This was a cross-sectional study of consecutive, consenting adults (18-65 years) with SUD registered to each of the nine participating addiction treatment services distributed across five Indian regions. We adapted the World Health Organization's pathway encounter form. Results: Of the 998 participants, 98% were males, 49.4% were rural, and 20% were indigenous population. Addiction services dominated initial (50%) and subsequent (60%) healthcare contacts. One in five contacted private for-profit healthcare. Primary care contact was rare (5/998). Diverse approaches included traditional healers (4-6%) and self-medication (2-8%). There was a 3-year delay in first contact; younger, educated individuals with opioid dependence preferred specialized services. Conclusion: There is a need to strengthen public healthcare infrastructure and delivery systems and integrate SUD treatment into public healthcare.

Defining a screening tool for post-traumatic stress disorder in East Africa: a penalized regression approach.

Background: Scalable PTSD screening strategies must be brief, accurate and capable of administration by a non-specialized workforce. Methods: We used PTSD as determined by the structured clinical interview as our gold standard and considered predictors sets of (a) Posttraumatic Stress Checklist-5 (PCL-5), (b) Primary Care PTSD Screen for the DSM-5 (PC-PTSD) and, (c) PCL-5 and PC-PTSD questions to identify the optimal items for PTSD screening for public sector settings in Kenya. A logistic regression model using LASSO was fit by minimizing the average squared error in the validation data. Area under the receiver operating characteristic curve (AUROC) measured discrimination performance. Results: Penalized regression analysis suggested a screening tool that sums the Likert scale values of two PCL-5 questions-intrusive thoughts of the stressful experience (#1) and insomnia (#21). This had an AUROC of 0.85 (using hold-out test data) for predicting PTSD as evaluated by the MINI, which outperformed the PC-PTSD. The AUROC was similar in subgroups defined by age, sex, and number of categories of trauma experienced (all AUROCs>0.83) except those with no trauma history- AUROC was 0.78. Conclusion: In some East African settings, a 2-item PTSD screening tool may outperform longer screeners and is easily scaled by a non-specialist workforce.

Understanding modifiable caregiver factors contributing to child development among young children in rural Malawi.

This study examined modifiable caregiver factors influencing child development in Malawi using baseline data from 1,021 mothers and their children <2 years of age participating in a cluster-randomized controlled trial implemented in rural Malawi (2022-2025). We fit an evidence-based theoretical model using structural equation modelling examining four caregiver factors: (1) diet diversity (sum of food groups consumed in the past 24 h), (2) empowerment (assessed using the project-level Women's Empowerment in Agriculture Index), (3) mental health (assessed using the Self-Reported Questionnaire, SRQ-20), and (4) stimulation (number of stimulation activities the mother engaged in the past 3 days). Child development was assessed using the Malawi Development Assessment Tool (norm-referenced aggregate Z-score). The model controlled for child, caregiver, and household socioeconomic characteristics. Results showed that caregiver dietary diversity was directly associated with higher child development scores (standardized coefficient 0.091 [95% CI 0.027, 0.153]) and lower SRQ-20 scores -0.058 (-0.111, -0.006). Empowerment was directly associated with higher child development scores (0.071 [0.007, 0.133]), higher stimulation score (0.074 [0.013, 0.140]), higher dietary diversity (0.085 [0.016, 0.145]), and lower SRQ-20 scores (-0.068 [-0.137, -0.002]). Further, higher empowerment was indirectly associated with improved child development through enhancement of caregiver dietary diversity, with an indirect effect of 0.008 (0.002, 0.018). These findings highlight the important role that caregiver diet and empowerment play in directly influencing child development and other aspects of caregiver well-being. Interventions aimed at enhancing child development should consider these factors as potential targets to improve outcomes for children and caregivers.

The Urban-Rural Divide in Neurocritical Care in Low-Income and Middle-Income Countries.

The term "urban-rural divide" encompasses several dimensions and has remained an important concern for any country. The economic disparity; lack of infrastructure; dearth of medical specialists; limited opportunities to education, training, and health care; lower level of sanitation; and isolating effect of geographical location deepens this gap, especially in low-income and middle-income countries (LMICs). This article gives an overview of the rural-urban differences in terms of facilities related to neurocritical care (NCC) in LMICs. Issues related to common clinical conditions such as stroke, traumatic brain injury, myasthenia gravis, epilepsy, tubercular meningitis, and tracheostomy are also discussed. To facilitate delivery of NCC in resource-limited settings, proposed strategies include strengthening preventive measures, focusing on basics, having a multidisciplinary approach, promoting training and education, and conducting cost-effective research and collaborative efforts. The rural areas of LMICs bear the maximum impact because of their limited access to preventive health services, high incidence of acquired brain injury, inability to have timely management of neurological emergencies, and scarcity of specialist services in a resource-deprived health center. An increase in the health budget allocation for rural areas, NCC education and training of the workforce, and provision of telemedicine services for rapid diagnosis, management, and neurorehabilitation are some of the steps that can be quite helpful.

Barriers and facilitators to the delivery of a biopsychosocial education and exercise programme for patients with chronic low back pain in Ghana. A qualitative study.

PURPOSE: Low back pain management has evolved with researchers advocating for a biopsychosocial management model. The biopsychosocial management model has been predominantly applied in high-income countries and underexplored in low- and middle-income countries including Ghana. This study aimed to explore the potential barriers and facilitators to patients with chronic low back pain (CLBP) and physiotherapists engagement with a biopsychosocial intervention (exercise and patient education) as part of a feasibility study. MATERIAL AND METHODS: This was a qualitative study embedded within a mixed-methods, sequential, feasibility study, in Ghana, applying semi-structured interviews. Two categories of participants involved in this study were, two trained physiotherapists, and six patients with CLBP, sampled within the feasibility study. RESULTS: Regarding the barriers and facilitators to the delivery of the BPS intervention, five interlinked themes emerged from the thematic analysis. These were: structure and process of delivery; patients' expectations; patients' health beliefs, autonomy, and engagement; external influences and personal and professional characteristics of physiotherapists. CONCLUSION: The themes that emerged from this study demonstrated many positive facilitators based on participants' improved understanding of LBP and the clarity and purpose of the biopsychosocial intervention. The results therefore demonstrate a potential to deliver the biopsychosocial intervention in a Ghanaian context.

A biopsychosocial approach to managing chronic low back pain offers a promising alternative to patients and physiotherapists in Ghana.A biopsychosocial approach to managing chronic low back pain has the potential to improve physiotherapists' thoughts and attitudes, and have a positive influence on their professional development in Ghana.A biopsychosocial approach to managing chronic low back pain has the potential to reverse patients' maladaptive beliefs, improve their understanding of their condition, improve outcomes in Ghana.

Use of artificial intelligence to address health disparities in low- and middle-income countries: a thematic analysis of ethical issues.

OBJECTIVES: Artificial intelligence (AI) is reshaping health and medicine, especially through its potential to address health disparities in low- and middle-income countries (LMICs). However, there are several issues associated with the use of AI that may reduce its impact and potentially exacerbate global health disparities. This study presents the key issues in AI deployment faced by LMICs. STUDY DESIGN: Thematic analysis. METHODS: PubMed, Scopus, Embase and the Web of Science databases were searched, from the date of their inception until September 2023, using the terms "artificial intelligence", "LMICs", "ethic∗" and "global health". Additional searches were conducted by snowballing references before and after the primary search. The final studies were chosen based on their relevance to the topic of this article. RESULTS: After reviewing 378 articles, 14 studies were included in the final analysis. A concept named the 'AI Deployment Paradox' was introduced to focus on the challenges of using AI to address health disparities in LMICs, and the following three categories were identified: (1) data poverty and contextual shifts; (2) cost-effectiveness and health equity; and (3) new technological colonisation and potential exploitation. CONCLUSIONS: The relationship between global health, AI and ethical considerations is an area that requires systematic investigation. Relying on health data inherent with structural biases and deploying AI without systematic ethical considerations may exacerbate global health inequalities. Addressing these challenges requires nuanced socio-political comprehension, localised stakeholder engagement, and well-considered ethical and regulatory frameworks.

A hybrid digital parenting programme to prevent abuse of adolescents in Tanzania: statistical analysis plan for a pragmatic cluster randomised controlled trial.

BACKGROUND: Globally, violence against children poses substantial health and economic challenges, with estimated costs nearing USD 7 trillion. This prompts the urgent call for effective evidence-based interventions in preventing and mitigating violence against children. ParentApp is a mobile, open-source application designed to offer a remote version of the Parenting for Lifelong Health (PLH) programme. ParentApp is the first digital parenting intervention for caregivers of adolescents aged 10-17 years to be tested in low- and middle-income settings. METHODS: This study is a pragmatic, two-arm, cluster-randomised trial in Mwanza, Tanzania's urban and peri-urban areas. Assessments are set for baseline, 1 month post-intervention, and 12 months post-intervention. We randomised 80 clusters, each with about 30 caregiver-adolescent dyads, with a 1:1 ratio stratified by urban or peri-urban location. Both arms receive an entry-level smartphone preloaded with Kiswahili apps-ParentApp for intervention and WashApp control. The primary method of analysis will be generalised linear mixed-effects models with adjustment for person-level characteristics and multiple imputation. In three-level models, measurement waves are nested within a person, nested within a sub-ward. Regressions will constrain groups to be equal at baseline and include covariates for stratification, percentage of male caregivers, and individual-level characteristics. DISCUSSIONS: Preparations for the trial began in December 2022, including community mobilisation and sensitisation. Rolling recruitment, baseline data collection, and implementation onboarding took place between April and September 2023. One-month post-test data collection began in August 2023 and thus far achieved 97% and 94% retention rates for caregivers and adolescents respectively. Final post-test data collection will begin in September 2024, anticipated to run until April 2025. This SAP was submitted to the journal before the interim analysis to preserve scientific integrity under a superiority hypothesis testing framework. TRIAL REGISTRATION: The trial was registered on the Open Science Framework on 14 March 2023: https://doi.org/10.17605/OSF.IO/T9FXZ . The trial protocol was published in Trials 25, 119 (2024): Baerecke, L., Ornellas, A., Wamoyi, J. et al.

Interventions addressing routine childhood immunization and its behavioral and social drivers.

Introduction: Despite the advances in vaccination, there are still several challenges in reaching millions of children in low- and middle-income countries (LMICs). In this review, we present an extensive summary of the various strategies used for improving routine immunization in LMICs to aid program implementers in designing vaccination interventions. Methods: Experimental and quasi-experimental impact evaluations conducted in LMICs evaluating the effectiveness of interventions in improving routine immunization of children aged 0-5 years or the intermediate outcomes were included from 3ie's review of systematic reviews. Some additional impact evaluation studies published in recent years in select LMICs with large number of unvaccinated children were also included. Studies were coded to identify interventions and the barriers in the study context using the intervention framework developed in 3ie's Evidence Gap Map and the WHO's Behavioral and Social Drivers (BeSD) of vaccination framework, respectively. Qualitative analysis of the content was conducted to analyze the intervention strategies and the vaccination barriers that they addressed. Results and conclusion: One hundred and forty-two impact evaluations were included to summarize the interventions. To address attitudinal and knowledge related barriers to vaccination and to motivate caregivers, sensitization and educational programs, media campaigns, and monetary or non-monetary incentives to caregivers, that may or may not be conditional upon certain health behaviors, have been used across contexts. To improve knowledge of vaccination, its place, time, and schedule, automated voice messages and written or pictorial messages have been used as standalone or multicomponent strategies. Interventions used to improve service quality included training and education of health workers and providing monetary or non-monetary perks to them or sending reminders to them on different aspects of provision of vaccination services. Interventions like effective planning or outreach activities, follow-up of children, tracking of children that have missed vaccinations, pay-for-performance schemes and health system strengthening have also been used to improve service access and quality. Interventions aimed at mobilizing and collaborating with the community to impact social norms, attitudes, and empower communities to make health decisions have also been widely implemented.
