Abstract Background Screening for HPV has led to significant reductions in cervical cancer deaths in high-income countries. However, the same results have not been achieved in low- and middle-income countries (LMICs). HPV self-sampling is a novel approach that could improve screening rates. Methods This study’s objective is to summarize the recent literature on HPV self-sampling in LMICs, focusing on sensitivity/specificity, and feasibility/acceptability of self-sampling compared to traditional screening methods. We conducted a PubMed search for articles published in English within the last 10 years on self-sampling in LMICs. Results Fifty eligible articles from 26 countries were included, 19 of which came from sub-Saharan Africa and 18 from Latin America/Caribbean. Seven studies examined sensitivity, with five reporting rates higher than 91%. Six reported on specificity, which was also very high at 86–97.8%. Six studies examined self-sampling concordance with provider-collected sampling, with concordance rates ranging from 87 to 97.5%. A total of 38 studies examined the feasibility/acceptability of HPV self-sampling. Participation rates were very high in all studies, even when self-sampling was done at participants’ homes (over 89% participation). Overall, participants reported that HPV self-sampling was easy to perform (75–97%, 18 studies), painless (60–90%, nine studies), and preferred over provider-collected sampling (57–100%, 14 studies). Eight studies reported follow-up rates for participants who completed self-sampling; however, these rates varied widely-from 13.7 to 90%. The major benefits of self-sampling include convenience of screening from home, less embarrassment, and less travel. Improved education and awareness of self-sampling, combined with support from community health workers, could reduce perceptions of self-sampling being inferior to provider-collected sampling. Improving follow-up of abnormal results and improving linkages to treatment are also essential. Conclusion Our literature review highlights HPV self-sampling is a well-performing test that shows promise in terms of expanding screening efforts for the prevention of cervical cancer-related deaths in LMICs.

Abstract 28 Background: The global burden of cancer is growing in low- and middle-income countries where availability of specialists to treat cancer is acutely low. To detect cancer earlier, patients must be educated about their risk for cancer and be screened when appropriate. In response to a growing need for cancer education in primary health care, ASCO International created the Cancer Control in Primary Care course, which was piloted in 2015. The purpose of the program is to increase the knowledge of primary health workers so as to recognize signs and symptoms of cancer, increase their ability to talk with patients about their risk, and to know how and when to refer patients for additional screening or diagnostic testing. Methods: ASCO collects data from participants in two stages: an on-site evaluation and a follow-up survey 12 months after the workshop. The survey instruments include questions about practice changes, learning objectives, and demographic information. Results: Follow-up surveys have been conducted for four courses. Ninety-three percent of respondents have reported that they made practice changes after the course. In addition, 90% reported that communication with patients about their risk for cancer had increased, 76% reported that they are screening patients for cancer more than before, and 74% reported that they have worked with specialists to plan treatment for their patients with cancer. Conclusion: Results of the Cancer Control in Primary Care course are positive, and ASCO will continue to collaborate with society and institutional partners to train primary health workers around the world to raise awareness of cancer.

IntroductionSince resources are finite, investing in services that produce the highest health gain ‘return on investment’ is critical. We assessed the extent to which low and middle-income countries (LMIC) have included cost-saving interventions in their national strategic health plans.MethodsWe used the Tufts Medical Center Global Health Cost-Effectiveness Analysis Registry, an open-source database of English-language cost-per-disability-adjusted life year (DALY) studies, to identify analyses published in the last 10 years (2008–2017) of cost-saving health interventions in LMICs. To assess whether countries prioritised cost-saving interventions within their latest national health strategic plans, we identified 10 countries, all in sub-Saharan Africa, with the highest measures on the global burden of disease scale and reviewed their national health priority plans.ResultsWe identified 392 studies (63%) targeting LMICs that reported 3315 cost-per-DALY ratios, of which 207 ratios (6%) represented interventions reported to be cost saving. Over half (53%) of these targeted sub-Saharan Africa. For the 10 countries we investigated in sub-Saharan Africa, 58% (79/137) of cost-saving interventions correspond with priorities identified in country plans. Alignment ranged from 95% (21/22 prioritised cost-saving ratios) in South Africa to 17% (2/12 prioritised cost-saving ratios) in Cameroon. Human papillomavirus vaccination was a noted priority in 70% (7/10) of national health prioritisation plans, while 40% (4/10) of countries explicitly included prenatal serological screening for syphilis. HIV prevention and treatment were stated priorities in most country health plans, whereas 40% (2/5) of countries principally outlined efforts for lymphatic filariasis. From our sample of 45 unique interventions, 36% of interventions (16/45) included costs associated directly with the implementation of the intervention.ConclusionOur findings indicate substantial variation across country and disease area in incorporating economic evidence into national health priority plans in a sample of sub-Saharan African countries. To make health economic data more salient, the authors of cost-effectiveness analyses must do more to reflect implementation costs and other factors that could limit healthcare delivery.

The majority of individuals with autism spectrum disorder live in low- and middle-income countries and receive little or no services from health or social care systems. The development and validation of autism spectrum disorder interventions has almost exclusively occurred in high-income countries, leaving many unanswered questions regarding what contextual factors would need to be considered to ensure the effectiveness of interventions in low- and middle-income countries. This study qualitatively explored contextual factors relevant to the adaptation of a caregiver-mediated early autism spectrum disorder intervention in a low-resource South African setting. We conducted four focus groups and four in-depth interviews with 28 caregivers of young children with autism spectrum disorder and used thematic analysis to identify key themes. Eight contextual factors including culture, language, location of treatment, cost of treatment, type of service provider, support, parenting practices, and stigma emerged as important. Caregivers reported a preference for an affordable, in-home, individualized early autism spectrum disorder intervention, where they have an active voice in shaping treatment goals. Distrust of community-based health workers and challenges associated with autism spectrum disorder-related stigma were identified. Recommendations that integrate caregiver preferences with the development of a low-cost and scalable caregiver-mediated early autism spectrum disorder intervention are included.

Abstract Background: This paper explores the extent of community-level stock-out of essential medicines among Community Health Workers (CHWs) in Low- and Middle-Income Countries (LMICs) and identifies the reasons for and consequences of essential medicine stock-outs. Methods: A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted. Five electronic databases were searched with a prespecified strategy and the grey literature examined, January 2006 - March 2021. Papers containing information on (i) the percentage of CHWs stocked out or (ii) reasons for stock-outs along the supply chain and consequences of stock-out were included and appraised for risk of bias. Outcomes were quantitative data on the extent of stock-out, summarized using descriptive statistics, and qualitative data regarding reasons for and consequences of stock-outs, analyzed using thematic content analysis and narrative synthesis. Results: Two reviewers screened 1083 records; 78 evaluations were included. Over the last fifteen years, CHWs experienced stock-outs of essential medicines nearly one third of the time and at a significantly (p < 0.01) higher rate than the health centers to which they are affiliated (28.93% [CI 95%: 28.79 - 29.07] vs 9.17 % [CI 95%: 8.64 - 9.70], respectively). A comparison of the period 2006-2015 and 2016-2021 showed a significant (p < 0.01) increase in CHW stock-out level from 26.36% [CI 95%: 26.22 -26.50] to 48.65% [CI 95%: 48.02- 49.28] while that of health centers increased from 7.79% [95% CI: 7.16 - 8.42] to 14.28% [95% CI: 11.22- 17.34]. Distribution barriers were the most cited reasons for stock-outs. Ultimately, patients were the most affected: stock-outs resulted in out-of-pocket expenses to buy unavailable medicines, poor adherence to medicine regimes, dissatisfaction, and low service utilization. Conclusion: Community-level stock-out of essential medicines constitutes a serious threat to achieving universal health coverage and equitable improvement of health outcomes. This paper suggests stock-outs are getting worse, and that there are particular barriers at the last mile. There is an urgent need to address the health and non-health system constraints that prevent the essential medicines procured for LMICs by international and national stakeholders from reaching the people who need them the most.

Background A high burden of preventable morbidity and mortality due to surgical site infections (SSIs) occurs in low- and middle-income countries (LMICs), and most of these SSIs occur following discharge. There is a high loss to follow-up due to a wide geographical spread of patients, and cost of travel can result in delayed and missed diagnoses. Objective This review analyzes the literature surrounding the use of telemedicine and assesses the feasibility of using mobile phone technology to both diagnose SSIs remotely in LMICs and to overcome social barriers. Methods A literature search was performed using Medline, Embase, CINAHL, PubMed, Web of Science, the Cochrane Central Register of Controlled Trials and Google Scholar. Included were English language papers reporting the use of telemedicine for detecting SSIs in comparison to the current practice of direct clinical diagnosis. Papers were excluded if infections were not due to surgical wounds, or if SSIs were not validated with in-person diagnosis. The primary outcome of this review was to review the feasibility of telemedicine for remote SSI detection. Results A total of 404 articles were screened and three studies were identified that reported on 2082 patients across three countries. All studies assessed the accuracy of remote diagnosis of SSIs using predetermined telephone questionnaires. In total, 44 SSIs were accurately detected using telemedicine and an additional 14 were picked up on clinical follow-up. Conclusions The use of telemedicine has shown to be a feasible method in remote diagnosis of SSIs. Telemedicine is a useful adjunct for clinical practice in LMICs to decrease loss to postsurgical follow-up.

Objective Migration of healthcare workers could result in shortage of human resources and rising inequalities in service provision in resource poor countries. The aim of this review was to determine the factors influencing the migration decisions of medical and dental graduates migrating from low- and middle-income countries as well as introducing a practical model for health professional’s migration. Methods Google Scholar and PubMed were searched together with relevant journals for English studies from January 2005 to January 2020. The original studies which evaluated the motivational factors of dental and medical graduates migrating from low or middle income countries were included. The migration model was developed by investigating the factors and frameworks of selected studies. Results Twenty-five articles were met the inclusion criteria. Push and pull theory was the most popular way to describe the driving factors of migration. These factors were classified into three macro-, meso- and micro-level with eight key domains.  Poor income, unfavorable socio-economic situation, political instability, lack of professional and educational opportunities together with family and personal concerns found as strong common reasons perpetuating migration. Conclusion Despite the fact that health workers migrate for different reasons, they follow a same route for decision to stay or leave their home countries. Un-fulfillment of expectations in mother land in addition to media reconstructed reality of life in foreign land can develop a positive attitude for better quality of life improvement after migration. Once individuals could overpass their national identity and barriers of migration, the final decision toward migration would be more feasible.

Background: Stroke is the second leading cause of death globally and an increasing concern in low- and middle-income countries (LMIC) where, due to limited capacity to treat stroke, preventative efforts are critically important. Although some research on evidence-based interventions for stroke prevention in LMIC exists, there remains a significant gap in understanding of their implementation across various contexts in LMIC. Objectives: In this scoping review, our objective was to identify and synthesize the implementation outcomes (using Proctor et al.’s taxonomy, 2011) for stroke prevention interventions, as well as to describe the diverse interventions employed. Methods: Eligible studies were empirical, focused on implementation of stroke prevention programs or policies, and occurred in at least one LMIC. Five databases were searched, including PubMed, PsycINFO, CINAHL, EMBASE, and Web of Science. Two reviewers independently assessed studies for selection and charted data; discrepancies were resolved through discussion with a third reviewer until consensus was reached. Narrative synthesis was used to analyze and interpret the findings. Results: Studies were predominantly focused in Asia, targeting primary or secondary prevention, and facility-based. Interventions were conducted at the level of individual (n=11), system (n=12), or both (n=4). Various implementation outcomes were reported, most commonly cost (n=10), acceptability (n=7), fidelity (n=7), and feasibility (n=6), but also adoption (n=4), penetration (n=3), appropriateness (n=1), and sustainability (n=1). Conclusions: Findings highlight the breadth of evidence-based interventions for stroke prevention available to implement in LMIC settings, including culturally acceptable education interventions, cost-effective medications, and community-based interventions implemented by community health workers. Implementation outcomes remain under-reported, and more rigorous research is needed to better plan and evaluate the implementation of these interventions to prevent stroke.
