Utilization of community health workers for malaria treatment: results from a three-year panel study in the districts of Kaya and Zorgho, Burkina Faso

Factors Associated with Communities' Satisfaction with Receiving Curative Care Administered by Community Health Workers in the Health Districts of Bousse and Boussouma in Burkina Faso, 2024

BACKGROUND

Since 2010, Burkina Faso has developed and initiated community-based management of childhood illnesses. Following the increased presence of community health workers and the adoption of free community health care, this study aims to assess community satisfaction with curative care administered by community health workers.

METHODOLOGY

This was a descriptive and analytical cross-sectional study. Data were collected in the health districts of Boussé and Boussouma from 20 February to 30 March 2023 for quantitative data and from 12 to 30 January 2024 for qualitative data using a questionnaire (household survey) and an interview grid (focus groups). Analyses were conducted using SPSS IBM 25 and Nvivo 14.

RESULTS

Households benefit from oral curative care when using Community health workers, but are not satisfied with the temporal accessibility of these community health workers. Temporal accessibility and awareness during care have a significant influence on household satisfaction.

CONCLUSIONS

Curative care by community health workers is effective, but its use could be improved by addressing the unavailability of community health workers, inputs and better communication during care.

Prevalence of asymptomatic malaria at the communal level in Burkina Faso: an application of the small area estimation approach

BACKGROUND

In malaria-endemic countries, asymptomatic carriers of plasmodium represent an important reservoir for malaria transmission. Estimating the burden at a fine scale and identifying areas at high risk of asymptomatic carriage are important to guide malaria control strategies. This study aimed to estimate the prevalence of asymptomatic carriage at the communal level in Burkina Faso, the smallest geographical entity from which a local development policy can be driven.

METHODS

The data used in this study came from several open sources: the 2018 Multiple Indicator Cluster Survey on Malaria and the 2019 general census of the population data and environmental. The analysis involved a total of 5489 children under 5 from the malaria survey and 293,715 children under 5 from the census. The Elbers Langjouw and Langjouw (ELL) approach is used to estimate the prevalence. This approach consists of including data from several sources (mainly census and survey data) in a statistical model to obtain predictive indicators at a sub-geographical level, which are not measured in the population census. The method achieves this by finding correlations between common census variables and survey data.

FINDINGS

The findings suggest that the spatial distribution of the prevalence of asymptomatic carriage is very heterogeneous across the communes. It varies from a minimum of 5.1% (95% CI 3.6-6.5) in the commune of Bobo-Dioulasso to a maximum of 41.4% (95% CI 33.5-49.4) in the commune of Djigoué. Of the 341 communes, 208 (61%) had prevalences above the national average of 20.3% (95% CI 18.8-21.2).

CONTRIBUTIONS

This analysis provided commune-level estimates of the prevalence of asymptomatic carriage of plasmodium in Burkina Faso. The results of this analysis should help to improve planning of malaria control at the communal level in Burkina Faso.

An examination of the structural linkages between households and community health services in realization of accelerated primary healthcare delivery in Kisumu County, Kenya: a systematic review

Background

The provision of community health services (CHS) is critical in accelerating primary health care delivery to vulnerable and deprived populations. This systematic review study has been conducted to interrogate the interrelationship between households and community health services in accelerating primary healthcare delivery synthesizing the available empirical studies. The findings are to inform a primary research on structural linkages between households and CHS in Kisumu County, Kenya.

Methods

This study applied a descriptive approach using a systematic review technique to provide context and substance to the two main research questions: (1) how does the interaction between households and CHWs affect utilization of CHS to promote equity and right to health? (2) How do health-seeking behaviours of households influence their decision-making regarding choices of CHS? We screened the literature from Google scholar, JSTOR, SAGE and EBSCO based on our inclusion criteria, resulting in 21 studies. These studies were assessed for quality and eligibility and data extracted based on relevance to the research study.

Results

Households place primacy on trust and confidentiality in the interaction with CHWs and this affects uptake of CHS. The social determinants of health are also critical in influencing the health-seeking behaviour of households and individuals and their choice of CHS. The successful models of CHS share the characteristic of community ownership and participation and provides for comprehensive health care teams.

Conclusion

CHS are critical for the acceleration of primary health care delivery. It forms an important pathway for the achievement of universal health coverage, which is an outcome required for Sustainable Development Goal 3 on health.

The longitudinal impact of an evidence-based multiple family group intervention (Amaka Amasanyufu) on oppositional defiant disorder and impaired functioning among children in Uganda: analysis of a cluster randomized trial from the SMART Africa-Uganda scale-up study (2016-2022)

BACKGROUND

Oppositional Defiant Disorders (ODDs) and other Disruptive Behavior Disorders (DBDs) are common among children and adolescents in poverty-impacted communities in sub-Saharan Africa. Without early intervention, its progression into adulthood can result in dire consequences. We examined the impact of a manualized family strengthening intervention called Amaka Amasanyufu designed to reduce ODDs and other DBDs among school-going children residing in low-resource communities in Uganda.

METHODS

We used longitudinal data from the SMART Africa-Uganda study (2016-2022). Public primary schools were randomized to: (1) Control condition (receiving usual care comprising generalized psychosocial functioning literature), 10 schools; (2) intervention delivered via parent peers (Amaka-parents), 8 schools or; (3) intervention delivered via community healthcare workers (Amaka-community), 8 schools. All the participants were blinded. At baseline, 8- and 16-weeks postintervention initiation, caregivers completed the Iowa Conners Scale, which measured Oppositional Defiant Disorder (ODD) and Impairment Rating Scale to evaluate children's overall impairment and impaired functioning with peers, siblings, and parents; impaired academic progress, self-esteem, and family functioning. Three-level linear mixed-effects models were fitted to each outcome. Pairwise comparisons of postbaseline group means within each time point were performed using Sidak's adjustment for multiple comparisons. Only children positive for ODD and other DBDs were analyzed.

RESULTS

Six hundred and thirty-six children screened positive for ODDs and other DBDs (Controls: n = 243; Amaka-parents: n = 194; Amaka-community: n = 199). At 8 weeks, Amaka-parents' children had significantly lower mean scores for overall impairment compared to controls, (mean difference: -0.71, p = .001), while Amaka-community children performed better on ODD (mean difference: -0.84, p = .016). At 16 weeks, children in both groups were performing better on ODD and IRS than controls, and there were no significant differences between the two intervention groups.

CONCLUSIONS

The Amaka Amasanyufu intervention was efficacious in reducing ODD and impaired functioning relative to usual care. Hence, the Amaka Amasanyufu intervention delivered either by Amaka-community or Amaka-parents has the potential to reduce negative behavioral health outcomes among young people in resource-limited settings and improve family functioning.

Stakeholder perceptions on the deployment of multiple first-line therapies for uncomplicated malaria: a qualitative study in the health district of Kaya, Burkina Faso

Background

In Burkina Faso, malaria remains the first cause of medical consultation and hospitalization in health centres. First-line case management of malaria in the country’s health facilities is based on the use of artemisinin-based combination therapy (ACT). To optimize the use of these anti-malarial drugs in the perspective of mitigating the emergence of artemisinin resistance, which is a serious threat to malaria control and elimination, a pilot programme using multiple first-line therapies (MFTs) [three artemisinin-based combinations—pyronaridine–artesunate, dihydroartemisinin–piperaquine and artemether-lumefantrine] has been designed for implementation. As the success of this MFT pilot programme depends on the perceptions of key stakeholders in the health system and community members, the study aimed to assess their perceptions on the implementation of this strategy.

Methods

Semi-structured interviews, including 27 individual in-depth interviews and 41 focus groups discussions, were conducted with key stakeholders including malaria control policymakers and implementers, health system managers, health workers and community members. Volunteers from targets stakeholder groups were randomly selected. All interviews were recorded, transcribed and translated. Content analysis was performed using the qualitative software programme QDA Miner.

Results

The interviews revealed a positive perception of stakeholders on the implementation of the planned MFT programme. They saw the strategy as an opportunity to strengthen the supply of anti-malarial drugs and improve the management of fever and malaria. However, due to lack of experience with the products, health workers and care givers expressed some reservations about the effectiveness and side-effect profiles of the two anti-malarial drugs included as first-line therapy in the MFT programme (pyronaridine–artesunate, dihydroartemisinin–piperaquine). Questions were raised about the appropriateness of segmenting the population into three groups and assigning a specific drug to each group.

Conclusion

The adherence of both populations and key stakeholders to the MFT implementation strategy will likely depend on the efficacy of the proposed drugs, the absence of, or low frequency of, side-effects, the cost of drugs and availability of the different combinations.

A Systematic Review and Meta-Analysis of Malaria Test Positivity Outcomes and Programme Interventions in Low Transmission Settings in Southern Africa, 2000-2021

Malaria is one of the most significant causes of mortality and morbidity globally, especially in sub-Saharan Africa (SSA) countries. It harmfully disturbs the public’s health and the economic growth of many developing countries. Despite the massive effect of malaria transmission, the overall pooled proportion of malaria positivity rate in Southern Africa is still elusive. Therefore, the objective of this systematic review and meta-analysis is to pool estimates of the incidence of the malaria positivity rate, which is the first of its kind in South African countries. A literature search is performed to identify all published articles reporting the incidence of malaria positivity in Southern Africa. Out of the 3359 articles identified, 17 studies meet the inclusion for systematic review and meta-analysis. In addition, because substantial heterogeneity is expected due to the studies being extracted from the universal population, random-effects meta-analyses are carried out to pool the incidence of the malaria positivity rate from diverse diagnostic methods. The result reveals that between-study variability is high (τ2 = 0.003; heterogeneity I2 = 99.91% with heterogeneity chi-square χ2 = 18,143.95, degree of freedom = 16 and a p-value < 0.0001) with the overall random pooled incidence of 10% (95%CI: 8−13%, I2 = 99.91%) in the malaria positivity rate. According to the diagnostic method called pooled incidence estimate, the rapid diagnostic test (RDT) is the leading diagnostic method (17%, 95%CI: 11−24%, I2 = 99.95%), followed by RDT and qPCR and RDT and loop mediated isothermal amplification (LAMP), respectively, found to be (3%, 95%CI: 2−3%, I2 = 0%) and (2%, 95%CI: 1−3%, I2 = 97.94%).Findings of the present study suggest high malaria positive incidence in the region. This implies that malaria control and elimination programmes towards malaria elimination could be negatively impacted and cause delays in actualising malaria elimination set dates. Further studies consisting of larger samples and continuous evaluation of malaria control programmes are recommended.

Using experience to create evidence: a mixed methods process evaluation of the new free family planning policy in Burkina Faso

BACKGROUND

In 2019, Burkina Faso was one of the first countries in Sub-Saharan Africa to introduce a free family planning (FP) policy. This process evaluation aims to identify obstacles and facilitators to its implementation, examine its coverage in the targeted population after six months, and investigate its influence on the perceived quality of FP services.

METHODS

This process evaluation was conducted from November 2019 through March 2020 in the two regions of Burkina Faso where the new policy was introduced as a pilot. Mixed methods were used with a convergent design. Semi-directed interviews were conducted with the Ministry of Health (n = 3), healthcare workers (n = 10), and women aged 15-49 years (n = 10). Surveys were also administered to the female members of 696 households randomly selected from four health districts (n = 901).

RESULTS

Implementation obstacles include insufficient communication, shortages of consumables and contraceptives, and delays in reimbursement from the government. The main facilitators were previous experience with free healthcare policies, good acceptability in the population, and support from local associations. Six months after its introduction, only 50% of the surveyed participants knew about the free FP policy. Higher education level, being sexually active or in a relationship, having recently seen a healthcare professional, and possession of a radio significantly increased the odds of knowing. Of the participants, 39% continued paying for FP services despite the new policy, mainly because of stock shortages forcing them to buy their contraceptive products elsewhere. Increased waiting time and shorter consultations were also reported.

CONCLUSION

Six months after its introduction, the free FP policy still has gaps in its implementation, as women continue to spend money for FP services and have little knowledge of the policy, particularly in the Cascades region. While its use is reportedly increasing, addressing implementation issues could further improve women's access to contraception.

Definitions of Severity in Treatment Seeking Studies of Febrile Illness in Children in Low and Middle Income Countries: A Scoping Review

Objectives: Understanding treatment seeking for severe febrile illness (SFI) is methodologically challenging. In this scoping review, we investigate definitions of severe febrile illness in treatment seeking studies on children under 5 years of age in low and middle income countries. We analyze the association of SFI definitions with different concepts of treatment seeking and identify related research gaps.

Methods: We searched Pubmed, Scopus and WHOLIS, and screened references of included publications for eligibility.

Results: Definitions of SFI had either a biomedical perspective (predominantly in quantitative studies) or a caregiver perspective (predominantly in qualitative studies). In quantitative analyses of treatment seeking, severity was more often conceptualized as a determinant rather than an outcome of a treatment seeking process. The majority of quantitative analyses only included surviving children or did not explicitly mention dead children.

Conclusion: Different research questions lead to diverse definitions and concepts of severity and treatment seeking outcomes, which limits the comparability of the available evidence. Systematic exclusion of dead children is likely to bias inferences on the association of treatment seeking and health outcomes of children with SFI in low and middle income countries.

Community Perceptions of Village Health Workers in Kisoro, Uganda

Background:

Village health workers (VHWs) can serve as a valuable resource to address public health needs in resource-limited settings such as Uganda. However, the successful implementation of VHW programs can be limited by poor acceptability among community members. Kisoro District Hospital (KDH) in Kisoro District, Uganda operates a VHW program and, at the time of the study, was expanding its services to 11 additional villages.

Objective:

The objective of this study was to evaluate community perceptions of VHWs in villages of Kisoro District with no prior exposure to the KDH VHW program in order to improve community acceptance when expanding the program to additional villages.

Methods:

We administered surveys to 658 community members from 11 villages to evaluate their perceptions of VHWs prior to receiving VHW services. Additionally, we conducted focus group discussions among 97 participants to explore perceptions of VHWs in further depth.

Findings:

Community members were generally accepting of VHWs. They preferred that VHWs provide both curative and preventive services across a broad range of health domains as opposed to a single disease. Expectations of the responsibilities of a VHW were influenced by agricultural occupational and household responsibilities, particularly for women. Participants expressed a preference to be actively involved in the selection and oversight of VHWs and that VHWs receive compensation.

Conclusions:

1) Community members’ expectations of VHWs are shaped by environmental, cultural, and social factors. 2) Active community engagement in the VHW program is key. 3) Aligning a VHW program with community perceptions may improve acceptance, in turn influencing effectiveness and sustainability. These findings were used to expand the KDH VHW Program into the participating villages in a manner consistent with community preferences. Our findings may provide guidance on enhancing the uptake of community-based VHW programs for VHW stakeholders and policymakers in other settings.

Moving From Community-Based to Health-Centre Based Management: Impact on Urban Community Health Worker Performance in Ethiopia

Community health worker (CHW) performance is influenced by the way in which management arrangements are configured vis-a-vis the community and health services. While low/middle-income contexts are changing, the literature provides few examples of country efforts to strategically modify management arrangements to support evolving CHW roles (e.g. chronic disease care) and operating environments (e.g. urbanization). This paper aims to understand the performance implications of changing from community-based to health centre-based management, on Ethiopia's Urban Health Extension Professionals (UHEPs), and the tensions/trade-offs associated with the respective arrangements. We conducted semi-structured interviews/focus groups to gather perspectives and preferences from those involved with the transition (13 managers/administrators, 5 facility-based health workers, 20 UHEPs). Using qualitative content analysis, we deductively coded data to four program elements impacted by changed management arrangements and known to affect CHW performance (work scope; community legitimacy; supervision/oversight/ownership; facility linkages) and inductively identified tensions/trade-offs. Community-based management was associated with wider work scope, stronger ownership/regular monitoring, weak technical support, and weak health center linkages, with opposite patterns observed for health center-led management. Practical trade-offs included: heavy UHEP involvement in political/administrative activities under Kebele-based management; resistance to working with UHEPs by facility-based workers; and, health centre capacity constraints in managing UHEPs. Whereas the Ministry of Health/UHEPs favoured health centre-led management to capitalize on UHEPs' technical skills, Kebele officials were vested in managing UHEPs and argued for community interests over UHEPs' professional interests; health facility managers/administrators held divided opinions. Management arrangements influence the nature of CHW contributions towards the achievement of health, development, and political goals. Decisions about appropriate management arrangements should align with the nature of CHW roles and consider implementation setting, including urbanization, political decentralization, and relative capacity of managing institutions.

The distinctive roles of urban community health workers in low- and middle-income countries: a scoping review of the literature

Addressing urban health challenges in low- and middle-income countries (LMICs) has been hampered by lack of evidence on effective mechanisms for delivering health services to the poor. The urban disadvantaged experience poor health outcomes (often worse than rural counterparts) and face service barriers. While community health workers (CHWs) have been extensively employed in rural communities to address inequities, little attention has been given to understanding the roles of CHWs in urban contexts. This study is the first to systematically examine urban CHW roles in LMICs. It aims to understand their roles vis-à-vis other health providers and raise considerations for informing future scope of practice and service delivery models. We developed a framework that presents seven key roles performed by urban CHWs and position these roles against a continuum of technical to political functions. Our scoping review included publications from four databases (MEDLINE, EMBASE, CINAHL and Social Sciences Citation Index) and two CHW resource hubs. We included all peer-reviewed, CHW studies situated in urban/peri-urban, LMIC contexts. We identify roles (un)commonly performed by urban CHWs, present the range of evidence available on CHW effectiveness in performing each role and identify considerations for informing future roles. Of 856 articles, 160 met the inclusion criteria. Programmes spanned 34 LMICs. Studies most commonly reported evidence on CHWs roles related to health education, outreach and elements of direct service provision. We found little overlap in roles between CHWs and other providers, with some exceptions. Reported roles were biased towards home visiting and individual-capacity building, and not well-oriented to reach men/youth/working women, support community empowerment or link with social services. Urban-specific adaptations to roles, such as peer outreach to high-risk, stigmatized communities, were limited. Innovation in urban CHW roles and a better understanding of the unique opportunities presented by urban settings is needed to fully capitalize on their potential.

The community health worker as service extender, cultural broker and social change agent: a critical interpretive synthesis of roles, intent and accountability

This paper is a critical interpretive synthesis of community health workers (CHWs) and accountability in low-income and middle-income countries. The guiding questions were: What factors promote or undermine CHWs as accountability agents? (and) Can these factors be intentionally fostered or suppressed to impel health system accountability? We conducted an iterative search that included articles addressing the core issue of CHWs and accountability, and articles addressing ancillary issues that emerged in the initial search, such as 'CHWs and equity.'CHWs are intended to comprise a 'bridge' between community members and the formal health system. This bridge function is described in three key ways: service extender, cultural broker, social change agent. We identified several factors that shape the bridging function CHWs play, and thus, their role in fomenting health system accountability to communities, including the local political context, extent and nature of CHW interactions with other community-based structures, health system treatment of CHWs, community perceptions of CHWs, and extent and type of CHW unionisation and collectivisation.Synthesising these findings, we elaborated several analytic propositions relating to the self-reinforcing nature of the factors shaping CHWs' bridging function; the roles of local and national governance; and the human resource and material capacity of the health system. Importantly, community embeddedness, as defined by acceptability, social connections and expertise, is a crucial attribute of CHW ability to foment local government accountability to communities.

Barriers to the utilization of community-based child and newborn health services in Ethiopia: a scoping review

The Ethiopian Federal Ministry of Health and partners have scaled up integrated community case management (iCCM) and community-based newborn care (CBNC), allowing health extension workers (HEWs) to manage the major causes of child and newborn death at the community level. However, low service uptake remains a key challenge. We conducted a scoping review of peer-reviewed and grey literature to assess barriers to the utilization of HEW services and to explore potential solutions. The review, which was conducted to inform the Optimizing the Health Extension Program project, which aimed to increase the utilization of iCCM and CBNC services, included 24 peer-reviewed articles and 18 grey literature documents. Demand-side barriers to utilization included lack of knowledge about the signs and symptoms of childhood illnesses and danger signs; low awareness of curative services offered by HEWs; preference for home-based care, traditional care, or religious intervention; distance, lack of transportation and cost of care seeking; the need to obtain husband’s permission to seek care and opposition of traditional or religious leaders. Supply-side barriers included health post closures, drug stockouts, disrespectful care and limited skill and confidence of HEWs, particularly with regard to the management of newborn illnesses. Potential solutions included community education and demand generation activities, finding ways to facilitate and subsidize transportation to health facilities, engaging family members and traditional and religious leaders, ensuring consistent availability of services at health posts and strengthening supervision and supply chain management. Both demand generation and improvement of service delivery are necessary to achieve the expected impact of iCCM and CBNC. Key steps for improving utilization would be carrying out multifaceted demand generation activities, ensuring availability of HEWs in health posts and ensuring consistent supplies of essential commodities. The Women’s Development Army has the potential to improving linkages between HEWs and communities, but this strategy needs to be strengthened to be effective.

Needs assessment of community health workers to enhance efficient delivery of their services for community case management of malaria in Kenya

Background

Malaria continues to be the leading cause of morbidity and mortality in Africa. Community Case Management of malaria (CCMm) which is undertaken by engaging Community Health Workers (CHWs) to effectively address management of malaria cases in some endemic communities was explored in this study. The aim was to assess the needs of CHWs that would help sustain and retain their services to enhance the efficient delivery of CCMm.

Methods

Using semi-structured questionnaires, data on the needs of CHWs was gathered through a qualitative study consisting of in-depth interviews and focus group discussions (FGDs) conducted among study participants in five districts in western Kenya. The study participants comprised of 100 CHWs, 100 mothers of children under five years and 25 key informants made up of public health officers and clinicians involved in the CCMm. The interviews were conducted in English and Swahili or Dholuo, the local language. The recorded audio interviews were transcribed later. The analysis was done using NVivo version 7 software and transcripts were coded after which themes related to the objectives of the study were identified.

Results

All the study participants recognized the need to train and update CHWs on their work as well as remunerating them for their services to enhance efficient delivery of services. The CHWs on their part perceived the provision of gloves, rapid diagnostic test kits (RDTs), lancets, cotton wool and ethanol, bins (to dispose of RDTs and lancets), together with drugs for treating clients as the essential needs to undertake CCMm in the communities. Other logistical needs and incentives mentioned by CHWs and key informants for the successful delivery of CCMm included: gumboots, raincoats, torch lights, mobile phones, means of transportation (bicycles and motorbikes), uniforms and ID cards for identification.

Conclusions

CHWs would perform tasks better and their services retained for a sustainable CCMm if: properly incentivized; offered refresher trainings (and updates) on malaria; and equipped with the requisite tools identified in this study.

Evaluating fidelity of community health worker roles in malaria prevention and control programs in Livingstone District, Zambia-A bottleneck analysis

BACKGROUND

Community Health Workers (CHWs) are an important human resource in improving community malaria intervention coverages and success in reducing malaria incidence has been attributed to them. However, despite this attribution, malaria resurgence cases have been reported in various countries including Zambia. This study aims to evaluate the implementation fidelity of CHW roles in malaria prevention and control programs in Livingstone through performance and service quality assessment.

METHODS

A mixed method concurrent cross-sectional study based on quantitative and qualitative approaches was used to evaluate performance and service quality of the CHW roles for selected catchments areas in Livingstone district. For the quantitative approach, (34) CHWs were interviewed and a community survey was also done with 464 community participants. For qualitative approach, two focused group discussions with CHWs and three key informant interviews from the CHW supervisors were done.

RESULTS

Overall implementation fidelity to the CHW roles was low with only 5(14.7%) of the CHWs having good performance and least good quality service while 29 (85.3%) performed poorly with substandard service. About 30% of house-holds reported having experienced malaria cases but CHWs had low coverage in testing with RDT (27%) for malaria index case service response with treatment at 14% coverage and provision of health education at 23%. For other households without malaria cases, only 27% had received malaria health education and 15% were screened for malaria. However, ITN distribution, sensitization for IRS were among other CHW services received by the community but were not documented in CHW registers for evaluation. Factors that shaped fidelity were being married, record for reports, supervision, and work experience as significant factors associated with performance. Lack of supplies, insufficient remuneration and lack of ownership by the supervising district were reported to hinder ideal implementation of the CHW strategy.

CONCLUSION

Fidelity to the malaria CHW roles was low as performance and quality of service was poor. A systems approach for malaria CHW facilitation considering supervision, stock supply and recruiting more CHWs on a more standardized level of recognition and remuneration would render an effective quality implementation of the CHW roles in malaria.

Coverage of community case management for malaria through CHWs: a quantitative assessment using primary household surveys of high-burden areas in Chhattisgarh state of India

BACKGROUND

Community Case Management of Malaria (CCMM) has been implemented through community health workers (CHWs) in many countries. Existing studies have shown that CHWs can be viable means of implementing CCMM. However, not many studies have examined the coverage under large-scale CCMM programmes. India is a big contributor to global malaria burden. Chhattisgarh is a leading state in India in terms of malaria incidence and mortality. CCMM was implemented on a large scale through the 'mitanin' CHWs in rural Chhattisgarh from 2015. Under CCMM, 37,696 CHWs in 84 high-burden administrative blocks of the state were trained and equipped with rapid diagnostic tests (RDT), artemisinin-based combination therapy (ACT) and chloroquine.

METHODS

This descriptive quantitative study assesses coverage of CCMM in detection and treatment of Malaria over three rounds of household surveys-2015, 2016 and 2018. Household-interviews covered more than 15,000 individuals in each round, using multi-stage random sampling across the 84 blocks. The main objectives were to find out the coverage in identification and treatment of malaria and the share of CHWs in them. A 15-days recall was used to find out cases of fever and healthcare sought by them.

RESULTS

In 2018, 62% of febrile cases in rural population contacted CHWs. RDT, ACT and chloroquine were available with 96%, 80% and 95% of CHWs, respectively. From 2015 to 2018, the share of CHWs in testing of febrile cases increased from 34 to 70%, while it increased from 28 to 69% in treatment of malaria cases. CHWs performed better than other providers in treatment-completion and administered medication under direct observation to 72% of cases they treated.

CONCLUSION

This study adds to one of the most crucial but relatively less reported area of CCMM programmes, i.e. the extent of coverage of the total febrile population by CHWs, which subsequently determines the actual coverage of case-management in malaria. Mitanin-CHWs achieved high coverage and treatment-completion rates that were rarely reported in context of large-scale CCMM elsewhere. Close to community, well-trained CHWs with sufficient supplies of rapid tests and anti-malarial drugs can play a key role in achieving the desired coverage in malaria-management.

Longitudinal analysis of the capacities of community health workers mobilized for seasonal malaria chemoprevention in Burkina Faso

Background

Seasonal malaria chemoprevention (SMC) relies on community health workers to distribute drugs. This study assessed: (1) the capacity of community-based distributors (CBDs) at the start and end of a campaign and from one campaign to another after training or refresher courses before each round; (2) to what extent CBDs’ experience over several campaigns contributed to measurable increase in their capacities; and (3) to what extent the training and experience of committed CBDs helped the less productive to catch up.

Methods

A longitudinal analysis was conducted in one Burkina Faso health district during the 2017 and 2018 campaigns. A panel including all CBDs was created. Their capacities were observed after: (1) initial training for the 2017 season; (2) refresher training for that year’s fourth round; and (3) initial training for the 2018 season. All were invited to complete a questionnaire at the end of training with 27 multiple-choice questions on their main tasks. Observers noted content coverage and conditions under which training sessions were conducted.

Results

The 612 CBDs showed, on average, high understanding of their tasks from the start of the annual campaigns. Tasks related to communicating with parents and reporting were best mastered. Their capacities grew from round to round and campaign to campaign, after most had undergone training and been supervised by head nurses. The greatest progress was in the technical components, considered more complex, which involved selecting eligible children, choosing the correct drug packet, and referring children to health professionals. Retaining CBDs from one round to the next benefited everyone, whatever their starting level. Groups that initially obtained the lowest scores (women, illiterates, youngest/oldest) progressed the most.

Conclusion

These results confirm the potential of using CBDs under routine programme implementation. Mandating CBDs with targeted tasks is a functional model, as they achieve mastery in this context where investments are made in training and supervision. Losing this specificity by extending CBDs’ mandates beyond SMC could have undesirable consequences. The added value of retaining committed CBDs is high. It is suggested that motivation and commitment be considered in recruitment, and that a supportive climate be created to foster retention.

Factors associated with home visits by volunteer community health workers to implement a home-fortification intervention in Bangladesh: a multilevel analysis

Objective:

BRAC, an international development organization based in Bangladesh, engages community health workers called Shasthya Shebikas (SS) to implement home fortification of foods with micronutrient powders (MNP). We identified factors associated with home visits by SS, at different levels of the BRAC programme-delivery hierarchy, to implement home-fortification interventions.

Design:

We conducted a cross-sectional survey, semi-structured interviews, and collected programme-related data from sub-districts included in the caregiver survey of BRAC’s home-fortification programme and performed multilevel logistic regression modelling to investigate factors associated with home visits by SS.

Settings:

Sixty-eight sub-districts in Bangladesh.

Participants:

Caregivers of children aged 6–59 months (n 1408) and BRAC’s SS (n 201).

Results:

Households with older children (0·55; 0·42, 0·72; P < 0·001) and located >300 m from the SS’s house (0·67; 0·50, 0·89; P = 0·006) were less likely to have been visited by the SS, whereas those with caregivers who had ≥5 years of schooling (1·53; 1·10, 2·12; P = 0·011) were more likely to have been visited by the SS (adjusted OR; 95 % CI). Households in the catchment area of older SS aged >50 years (0·44; 0·21, 0·90; P = 0·025) were less likely to have been visited by the SS, whereas those with SS who received incentives of >800 BDT (3·00; 1·58, 5·58; P = 0·001) were more likely to have been visited by the SS (adjusted OR; 95 % CI).

Conclusions:

The number of home visits is a function of the characteristics of SS, factors that characterize the households they serve and characteristics of their organizational context, particularly to implement home fortification of foods with MNP.

Proactive case detection of common childhood illnesses by community health workers: a systematic review

INTRODUCTION

Identifying design features and implementation strategies to optimise community health worker (CHW) programmes is important in the context of mixed results at scale. We systematically reviewed evidence of the effects of proactive case detection by CHWs in low-income and middle-income countries (LMICs) on mortality, morbidity and access to care for common childhood illnesses.

METHODS

Published studies were identified via electronic databases from 1978 to 2017. We included randomised and non-randomised controlled trials, controlled before-after studies and interrupted time series studies, and assessed their quality for risk of bias. We reported measures of effect as study investigators reported them, and synthesised by outcomes of mortality, disease prevalence, hospitalisation and access to treatment. We calculated risk ratios (RRs) as a principal summary measure, with CIs adjusted for cluster design effect.

RESULTS

We identified 14 studies of 11 interventions from nine LMICs that met inclusion criteria. They showed considerable diversity in intervention design and implementation, comparison, outcomes and study quality, which precluded meta-analysis. Proactive case detection may reduce infant mortality (RR: 0.52-0.94) and increase access to effective treatment (RR: 1.59-4.64) compared with conventional community-based healthcare delivery (low certainty evidence). It is uncertain whether proactive case detection reduces mortality among children under 5 years (RR: 0.04-0.80), prevalence of infectious diseases (RR: 0.06-1.02), hospitalisation (RR: 0.38-1.26) or increases access to prompt treatment (RR: 1.00-2.39) because the certainty of this evidence is very low.

CONCLUSION

Proactive case detection may provide promising benefits for child health, but evidence is insufficient to draw conclusions. More research is needed on proactive case detection with rigorous study designs that use standardised outcomes and measurement methods, and report more detail on complex intervention design and implementation.

Proximity to a community health worker is associated with utilization of malaria treatment services in the community among under-five children: a cross-sectional study in rural Uganda

BACKGROUND

In rural areas of sub-Saharan Africa, health facilities are difficult to access for prompt treatment of malaria. Community health workers (CHWs) have been trained and equipped to treat malaria. Utilization of their service has not been adequately evaluated. The aim of this study was to determine the level of utilization of CHWs, and whether distance and other factors influence the utilization.

METHODS

The authors conducted a cross-sectional study among households with a child below 5 y of age and interviewed caregivers in Sheema district, rural western Uganda. Logistic regression was used to calculate adjusted ORs (aOR) for factors associated with use of CHW services.

RESULTS

Among 547 households, 64% (338/528) reported using CHWs as the first point of consultation for their febrile children. Factors associated with the use of CHWs services were lower asset index (aOR=1.9, p=0.02), mother being the decision maker for site of first consultation (aOR=1.9, p=0.01), distance to nearest CHW of <3 km (aOR=2.1, p=0.03) compared to >3 km, and trust for CHWs services (aOR=7.8, p<0.001).

CONCLUSION

Proximal location to a CHW is associated with use of CHW services. Programs should ensure that CHW are well located to enable easy access.

Proactive community case management and child survival: protocol for a cluster randomised controlled trial

INTRODUCTION

Community health workers (CHWs)-shown to improve access to care and reduce maternal, newborn, and child morbidity and mortality-are re-emerging as a key strategy to achieve health-related Sustainable Development Goals (SDGs). However, recent evaluations of national programmes for CHW-led integrated community case management (iCCM) of common childhood illnesses have not found benefits on access to care and child mortality. Developing innovative ways to maximise the potential benefits of iCCM is critical to achieving the SDGs.

METHODS AND ANALYSIS

An unblinded, cluster randomised controlled trial in rural Mali aims to test the efficacy of the addition of door-to-door proactive case detection by CHWs compared with a conventional approach to iCCM service delivery in reducing under-five mortality. In the intervention arm, 69 village clusters will have CHWs who conduct daily proactive case-finding home visits and deliver doorstep counsel, care, referral and follow-up. In the control arm, 68 village clusters will have CHWs who provide the same services exclusively out of a fixed community health site. A baseline population census will be conducted of all people living in the study area. All women of reproductive age will be enrolled in the study and surveyed at baseline, 12, 24 and 36 months. The survey includes a life table tracking all live births and deaths occurring prior to enrolment through the 36 months of follow-up in order to measure the primary endpoint: under-five mortality, measured as deaths among children under 5 years of age per 1000 person-years at risk of mortality.

ETHICS AND DISSEMINATION

The trial has received ethical approval from the Ethics Committee of the Faculty of Medicine, Pharmacy and Dentistry, University of Bamako. The results will be disseminated through peer-reviewed publications, national and international conferences and workshops, and media outlets.

Analysis of the quality of seasonal malaria chemoprevention provided by community health Workers in Boulsa health district, Burkina Faso

Background

Since 2014, the Burkina Faso government has made Seasonal Malaria Chemoprevention (SMC) a priority in its strategic plan to fight against malaria among children aged from 3 to 59 months. Very few studies have examined the care provided by community health workers in the framework of this strategy. The purpose of this study was to evaluate the level of quality of care provided by the latter.

Methods

This was a mixed study. The quantitative component consisted of a non-participant observation of community health workers during the administration of care. The qualitative component consisted of one-on-one interviews with community health workers, child caregivers and head nurses. Five dimensions (organizational accessibility, interpersonal relationship, technical competence, safety of care and satisfaction of child caregivers) adapted from the Donabedian quality of care model were used to assess the quality level of care. The Corlien et al. Health Systems Research Program Implementation Scale was used to establish quality scores for each of the five dimensions. The study sites were the health centers located in the administrative centers of the 4 communes of the health district of Boulsa. The data were collected during the first cycle of the 2017 SMC campaign.

Results

A total of 14 active pairs (28 CHWs) were observed and 40 in-depth interviews with community health workers, Head nurses in duty and community leaders were conducted. The results show that community health workers worked in pairs. They had all received SMC training and possessed equipment to do their job. The dimensions of organizational accessibility and satisfaction of the caregivers were rated as good. The dimensions of interpersonal relationship and technical competence were judged to be of an acceptable score. Safety of care was judged to be of a low-level score. The overall quality of care was considered acceptable.

Conclusion

The results of this study have shown that despite the difficulties faced by community health workers, they manage to deliver acceptable quality of care. Their use would be an asset for SMC in particular and for the health system in general.

Exploring communities' and health workers' perceptions of indicators and drivers of malaria decline in Malindi, Kenya

BACKGROUND

Since 2000, a decrease in malaria burden has been observed in most endemic countries. Declining infection rates and disease burden and reduction in asymptomatic carriers are the outcome of improved quality of care and related health system factors. These include improved case management through better diagnosis, implementation of highly effective antimalarial drugs and increased use of bednets. We studied communities' and health workers' perceptions of indicators and drivers in the context of decreasing malaria transmission in Malindi, Kenya.

MATERIALS AND METHODS

A variety of qualitative methods that included participatory rural appraisal (PRA) tools such as community river of life and trend lines, focus group discussions (FGDs) and key informant interviews were used. Studies took place between November 2013 and April 2014.

RESULTS

Providing residents with bednets contributed to malaria reduction, and increasing community awareness on the causes and symptoms of malaria and improved malaria treatment were also perceived to contribute to the decline of malaria. The study identified three perceived drivers to the reported decline in malaria: a) community health workers' enhanced awareness creation towards household owners regarding malaria-related activities through visitations and awareness sessions, b) Women involvement in Savings Internal Lending Community was perceived to have increased their financial base, thereby improving their decision-making power towards the care of their sick child(ren), c) Non Governmental Organizations (NGOs) and partners played a promoter part in health and general economic development initiatives.

CONCLUSIONS

To achieve the goal of malaria elimination, collaboration between governmental and NGOs will be crucial when improving the financial base of women and enhancing participation of community health workers.

Impact of training of mothers, drug shop attendants and voluntary health workers on effective diagnosis and treatment of malaria in Lagos, Nigeria

Background:

The National Malaria Eradication Program and international agencies are keen on scaling up the use of malaria rapid diagnostic tests (mRDTs) and artemisinin-based combination therapies (ACTs) for effective diagnosis and treatment of the disease. However, poor diagnostic skills and inappropriate treatment are limiting the efforts. In Nigeria, a large proportion of infected patients self-diagnose and treat while many others seek care from informal drug attendants and voluntary health workers.

Aims:

This study describes the impact of training voluntary health workers, drug shop attendants, and mothers on effective case detection and treatment of malaria in Lagos, Nigeria. METHODS: We trained mothers accessing antenatal care, drug shop attendants, and voluntary health workers selected from the three districts of Lagos, on the use of histidine-rich protein-2-based mRDTs and ACTs. Pre- and post-training assessments, focus group discussions (FGDs), and in-depth interviews (IDIs) were carried out.

Results:

The knowledge, attitude, and skill of the participants to achieve the goal of “test, treat, and track” using mRDT and ACTs were low (11%–55%). There was a low awareness of other non-malaria fevers among mothers. Self-medication was widely practiced (31.3%). FGDs and IDIs revealed that health-care providers administered antimalarials without diagnosis. Training significantly improved participants' knowledge and expertise on the use of mRDTs and ACTs (P = 0.02). The participants' field performance on mRDT use was significantly correlated with their category (bivariate r = 0.51, P = 0.001). There was no statistically significant association between the participants' level of education or previous field experience and their field performance on mRDT (r = 0.12, P = 0.9; χ ²= 38, df = 2 and P = 0.49).

Conclusion:

These findings suggest that training of stakeholders in malaria control improves diagnosis and treatment of malaria. However, a broader scope of training in other settings may be required for an effective malaria control in Nigeria.

Spatial distribution and determinants of asymptomatic malaria risk among children under 5 years in 24 districts in Burkina Faso

BACKGROUND

In malaria endemic countries, asymptomatic cases constitute an important reservoir of infections sustaining transmission. Estimating the burden of the asymptomatic population and identifying areas with elevated risk is important for malaria control in Burkina Faso. This study analysed the spatial distribution of asymptomatic malaria infection among children under 5 in 24 health districts in Burkina Faso and identified the determinants of this distribution.

METHODS

The data used in this study were collected in a baseline survey on "evaluation of the impact of pay for performance on the quality of care" conducted in 24 health districts in Burkina Faso, between October 2013 and March 2014. This survey involved 7844 households and 1387 community health workers. A Bayesian hierarchical logistic model that included spatial dependence and covariates was implemented to identify the determinants of asymptomatic malaria infection. The posterior probability distribution of a parameter from the model was summarized using odds ratio (OR) and 95% credible interval (95% CI).

RESULTS

The overall prevalence of asymptomatic malaria infection in children under 5 years of age was estimated at 38.2%. However, significant variation was observed between districts ranging from 11.1% in the district of Barsalgho to 77.8% in the district of Gaoua. Older children (48-59 vs < 6 months: OR: 6.79 [5.62, 8.22]), children from very poor households (Richest vs poorest: OR: 0.85 [0.74-0.96]), households located more than 5 km from a health facility (< 5 km vs  ≥ 5 km: OR: 1.14 [1.04-1.25]), in localities with inadequate number of nurses (< 3 vs  ≥ 3: 0.72 [0.62, 0.82], from rural areas (OR: 1.67 [1.39-2.01]) and those surveyed in high transmission period of asymptomatic malaria (OR: 1.27 [1.10-1.46]) were most at risk for asymptomatic malaria infection. In addition, the spatial analysis identified the following nine districts that reported significantly higher risks: Batié, Boromo, Dano, Diébougou, Gaoua, Ouahigouya, Ouargaye, Sapouy and Toma. The district of Zabré reported the lowest risk.

CONCLUSION

The analysis of spatial distribution of infectious reservoir allowed the identification of risk areas as well as the identification of individual and contextual factors. Such national spatial analysis should help to prioritize areas for increased malaria control activities.

Distance to care, care seeking and child mortality in rural Burkina Faso: findings from a population-based cross-sectional survey

Objective

Although distance has been identified as an important barrier to care, evidence for an effect of distance to care on child mortality is inconsistent. We investigated the association of distance to care with self‐reported care seeking behaviours, neonatal and post‐neonatal under‐five child mortality in rural areas of Burkina Faso.

Methods

We performed a cross‐sectional survey in 14 rural areas from November 2014 to March 2015. About 100 000 women were interviewed on their pregnancy history and about 5000 mothers were interviewed on their care seeking behaviours. Euclidean distances to the closest facility were calculated. Mixed‐effects logistic and Poisson regressions were used respectively to compute odds ratios for care seeking behaviours and rate ratios for child mortality during the 5 years prior to the survey.

Results

Thirty per cent of the children lived more than 7 km from a facility. After controlling for confounding factors, there was a strong evidence of a decreasing trend in care seeking with increasing distance to care (P ≤ 0.005). There was evidence for an increasing trend in early neonatal mortality with increasing distance to care (P = 0.028), but not for late neonatal mortality (P = 0.479) and post‐neonatal under‐five child mortality (P = 0.488). In their first week of life, neonates living 7 km or more from a facility had an 18% higher mortality rate than neonates living within 2 km of a facility (RR = 1.18; 95%CI 1.00, 1.39; P = 0.056). In the late neonatal period, despite the lack of evidence for an association of mortality with distance, it is noteworthy that rate ratios were consistent with a trend and similar to or larger than estimates in early neonatal mortality. In this period, neonates living 7 km or more from a facility had an 18% higher mortality rate than neonates living within 2 km of a facility (RR = 1.18; 95%CI 0.92, 1.52; P = 0.202). Thus, the lack of evidence may reflect lower power due to fewer deaths rather than a weaker association.

Conclusion

While better geographic access to care is strongly associated with increased care seeking in rural Burkina Faso, the impact on child mortality appears to be marginal. This suggests that, in addition to improving access to services, attention needs to be paid to quality of those services.

Household costs and time to treatment for children with severe febrile illness in rural Burkina Faso: the role of rectal artesunate

Background

Community health workers (CHWs) were trained to identify children with malaria who could not take oral medication, treat them with rectal artesunate (RA) and refer them to the closest healthcare facility to complete management. However, many children with such symptoms did not seek CHWs’ care. The hypothesis was that the cost of referral to a health facility was a deterrent. The goal of this study was to compare the out-of-pocket costs and time to seek treatment for children who sought CHW care (and received RA) versus those who did not.

Methods

Children with symptoms of severe malaria receiving RA at CHWs and children with comparable disease symptoms who did not go to a CHW were identified and their parents were interviewed. Household out-of-pocket costs per illness episode and speed of treatment were evaluated and compared between RA-treated children vs. non-RA treated children and by central nervous symptoms (CNS: repeated convulsions, altered consciousness or coma).

Results

Among children with CNS symptoms, costs of RA-treated children were similar to those of non-RA treated children ($5.83 vs. $4.65; p = 0.52), despite higher transport costs ($2.74 vs. $0.91; p < 0.0001). However, among children without CNS symptoms, costs of RA-treated children were higher than the costs of non-RA treated children with similar symptoms ($5.62 vs. $2.59; p = 0.0001), and the main driver of the cost difference was transport. After illness onset, CNS children reached CHWs for RA an average of 9.0 h vs. 16.1 h for non-RA treated children reaching first treatment [difference 7.1 h (95% CI − 1.8 to 16.1), p = 0.11]. For non-CNS patients the average time to CHW-delivered RA treatment was 12.2 h vs. 20.1 h for those reaching first treatment [difference 7.9 h (95% CI 0.2–15.6), p = 0.04]. More non-RA treated children developed CNS symptoms before arrival at the health centre but the difference was not statistically significant (6% vs. 4%; p = 0.58).

Conclusions

Community health worker-delivered RA does not affect the total out-of-pocket costs when used in children with CNS symptoms, but is associated with higher total out-of-pocket costs when used in children with less severe symptoms. RA-treated children sought treatment more quickly.

The feasibility of task-sharing the identification, emergency treatment, and referral for women with pre-eclampsia by community health workers in India

BACKGROUND

Hypertensive disorders are the second highest direct obstetric cause of maternal death after haemorrhage, accounting for 14% of maternal deaths globally. Pregnancy hypertension contributes to maternal deaths, particularly in low- and middle-income countries, due to a scarcity of doctors providing evidence-based emergency obstetric care. Task-sharing some obstetric responsibilities may help to reduce the mortality rates. This study was conducted to assess acceptability by the community and other healthcare providers, for task-sharing by community health workers (CHW) in the identification and initial care in hypertensive disorders in pregnancy.

METHODS

This study was conducted in two districts of Karnataka state in south India. A total of 14 focus group discussions were convened with various community representatives: women of reproductive age (N = 6), male decision-makers (N = 2), female decision-makers (N = 3), and community leaders (N = 3). One-to-one interviews were held with medical officers (N = 2), private healthcare OBGYN specialists (N = 2), senior health administrators (N = 2), Taluka (county) health officers (N = 2), and obstetricians (N = 4). All data collection was facilitated by local researchers familiar with the setting and language. Data were subsequently transcribed, translated and analysed thematically using NVivo 10 software.

RESULTS

There was strong community support for home visits by CHW to measure the blood pressure of pregnant women; however, respondents were concerned about their knowledge, training and effectiveness. The treatment with oral antihypertensive agents and magnesium sulphate in emergencies was accepted by community representatives but medical practitioners and health administrators had reservations, and insisted on emergency transport to a higher facility. The most important barriers for task-sharing were concerns regarding insufficient training, limited availability of medications, the questionable validity of blood pressure devices, and the ability of CHW to correctly diagnose and intervene in cases of hypertensive disorders of pregnancy.

CONCLUSION

Task-sharing to community-based health workers has potential to facilitate early diagnosis of the hypertensive disorders of pregnancy and assist in the provision of emergency care. We identified some facilitators and barriers for successful task-sharing of emergency obstetric care aimed at reducing mortality and morbidity due to hypertensive disorders of pregnancy.

Integrated primary health care in low- and middle-income countries: a double challenge

Background

The lack of primary healthcare integration has been identified as one of the main limits to programs’ efficacy in low- and middle-income countries. This is especially relevant to the Millennium Development Goals, whose health objectives were not attained in many countries at their term in 2015. While global health scholars and decision-makers are unanimous in calling for integration, the objective here is to go further and contribute to its promotion by presenting two of the most important challenges to be met for its achievement: 1) developing a “crosswise approach” to implementation that is operational and effective; and 2) creating synergy between national programs and interventions driven by non-State actors.

Main body

The argument for urgently addressing this double challenge is illustrated by drawing on observations made and lessons learned during a four-year research project (2011–2014) evaluating the effects of interventions against malaria in Burkina Faso. The way interventions were framed was mostly vertical, leaving little room for local adaptation. In addition, many non-governmental organizations intervened and contributed to a fragmented and heteronomous health governance system. Important ethical issues stem from how interventions against malaria were shaped and implemented in Burkina Faso. To further explore this issue, a scoping literature review was conducted in August 2016 on the theme of integrated primary healthcare. It revealed that no clear definition of the concept has been advanced or endorsed thus far. We call for caution in conceptualizing it as a simple juxtaposition of different tasks or missions at the primary care level. It is time to go beyond the debate around selective versus comprehensive approaches or fragmentation versus cohesion. Integration should be thought of as a process to reconcile these tensions.

Conclusions

In the context that characterizes many low- and middle-income countries today, better aid coordination and public health systems strengthening, as promoted by multisectoral approaches, might be among the best options to sustainably and ethically integrate primary healthcare interventions.

Measuring effective coverage of curative child health services in rural Burkina Faso: a cross-sectional study

OBJECTIVE

To estimate both crude and effective curative health services coverage provided by rural health facilities to under 5-year-old (U5YO) children in Burkina Faso.

METHODS

We surveyed 1298 child health providers and 1681 clinical cases across 494 primary-level health facilities, as well as 12 497 U5YO children across 7347households in the facilities' catchment areas. Facilities were scored based on a set of indicators along three quality-of-care dimensions: management of common childhood diseases, management of severe childhood diseases and general service readiness. Linking service quality to service utilisation, we estimated both crude and effective coverage of U5YO children by these selected curative services.

RESULTS

Measured performance quality among facilities was generally low with only 12.7% of facilities surveyed reaching our definition of high and 57.1% our definition of intermediate quality of care. The crude coverage was 69.5% while the effective coverages indicated that 5.3% and 44.6% of children reporting an illness episode received services of only high or high and intermediate quality, respectively.

CONCLUSION

Our study showed that the quality of U5YO child health services provided by primary-level health facilities in Burkina Faso was low, resulting in relatively ineffective population coverage. Poor adherence to clinical treatment guidelines combined with the lack of equipment and qualified clinical staff that performed U5YO consultations seemed to be contributors to the gap between crude and effective coverage.

Towards a framework for analyzing determinants of performance of community health workers in malaria prevention and control: a systematic review

BACKGROUND

Community health workers (CHWs) are an important human resource in improving coverage of and success to interventions aimed at reducing malaria incidence. Evidence suggests that the performance of CHWs in malaria programs varies in different contexts. However, comprehensive frameworks, based on systematic reviews, to guide the analysis of determinants of performance of CHWs in malaria prevention and control programs are lacking.

METHODS

We systematically searched Google Scholar, Science Direct, and PubMed including reference lists that had English language publications. We included 16 full text articles that evaluated CHW performance in malaria control. Search terms were used and studies that had performance as an outcome of interest attributed to community-based interventions done by CHWs were included.

RESULTS

Sixteen studies were included in the final review and were mostly on malaria Rapid Diagnosis and Treatment, as well as adherence to referral guidelines. Factors determining performance and effective implementation of CHW malaria programs included health system factors such as nature of training of CHWs; type of supervision including feedback process; availability of stocks, supplies, and job aids; nature of work environment and reporting systems; availability of financial resources and transport systems; types of remuneration; health staff confidence in CHWs; and workload. In addition, community dynamics such as nature of community connectedness and support from the community and utilization of services by the community also influenced performance. Furthermore, community health worker characteristics such marital status, sex, and CHW confidence levels also shaped CHW performance.

CONCLUSIONS

Effectively analyzing and promoting the performance of CHWs in malaria prevention and control programs may require adopting a framework that considers health systems and community factors as well as community health worker characteristics.

Proactive community case management and child survival in periurban Mali

The majority of the world's population lives in urban areas, and regions with the highest under-five mortality rates are urbanising rapidly. This 7-year interrupted time series study measured early access to care and under-five mortality over the course of a proactive community case management (ProCCM) intervention in periurban Mali. Using a cluster-based, population-weighted sampling methodology, we conducted independent cross-sectional household surveys at baseline and at 12, 24, 36, 48, 60, 72 and 84 months later in the intervention area. The ProCCM intervention had five key components: (1) active case detection by community health workers (CHWs), (2) CHW doorstep care, (3) monthly dedicated supervision for CHWs, (4) removal of user fees and (5) primary care infrastructure improvements and staff capacity building. Under-five mortality rate was calculated using a Cox proportional hazard survival regression. We measured the percentage of children initiating effective antimalarial treatment within 24 hours of symptom onset and the percentage of children reported to be febrile within the previous 2 weeks. During the intervention, the rate of early effective antimalarial treatment of children 0-59 months more than doubled, from 14.7% in 2008 to 35.3% in 2015 (OR 3.198, P<0.0001). The prevalence of febrile illness among children under 5 years declined after 7 years of the intervention from 39.7% at baseline to 22.6% in 2015 (OR 0.448, P<0.0001). Communities where ProCCM was implemented have achieved an under-five mortality rate at or below 28/1000 for the past 6 years. In 2015, under-five mortality was 7/1000 (HR 0.039, P<0.0001). Further research is needed to elucidate the mechanisms of action and generalizability of ProCCM.

Impact Evaluation of Seasonal Malaria Chemoprevention under Routine Program Implementation: A Quasi-Experimental Study in Burkina Faso

Seasonal malaria chemoprevention (SMC) for children < 5 is a strategy that is gaining popularity in West African countries. Although its efficacy to reduce malaria incidence has been demonstrated in trials, the effects of SMC implemented in routine program conditions, outside of experimental contexts, are unknown. In 2014 and 2015, a survey was conducted in 1,311 households located in Kaya District (Burkina Faso) where SMC had been recently introduced. All children < 72 months were tested for malaria and anemia. A pre–post study with control group was designed to measure SMC impact during high transmission season. A difference-in-differences approach was coupled in the analysis with propensity score weighting to control for observable and time-invariant nonobservable confounding factors. SMC reduced the parasitemia point and period prevalence by 3.3 and 24% points, respectively; this translated into protective effects of 51% and 62%. SMC also reduced the likelihood of having moderate to severe anemia by 32%, and history of recent fever by 46%. Self-reported coverage for children at the first cycle was 83%. The SMC program was successfully added to a package of interventions already in place. To our knowledge, with prevalence < 10% during the peak of the transmission season, this is the first time that malaria can be reported as hypo-endemic in a sub-Sahelian setting in Burkina Faso. SMC has great potential, and along with other interventions, it could contribute to approaching the threshold where elimination strategies will be envisioned in Burkina Faso.

Integrated community case management in a peri-urban setting: a qualitative evaluation in Wakiso District, Uganda

BACKGROUND

Integrated community case management (iCCM) strategies aim to reach poor communities by providing timely access to treatment for malaria, pneumonia and diarrhoea for children under 5 years of age. Community health workers, known as Village Health Teams (VHTs) in Uganda, have been shown to be effective in hard-to-reach, underserved areas, but there is little evidence to support iCCM as an appropriate strategy in non-rural contexts. This study aimed to inform future iCCM implementation by exploring caregiver and VHT member perceptions of the value and effectiveness of iCCM in peri-urban settings in Uganda.

METHODS

A qualitative evaluation was conducted in seven villages in Wakiso district, a rapidly urbanising area in central Uganda. Villages were purposively selected, spanning a range of peri-urban settlements experiencing rapid population change. In each village, rapid appraisal activities were undertaken separately with purposively selected caregivers (n = 85) and all iCCM-trained VHT members (n = 14), providing platforms for group discussions. Fifteen key informant interviews were also conducted with community leaders and VHT members. Thematic analysis was based on the 'Health Access Livelihoods Framework'.

RESULTS

iCCM was perceived to facilitate timely treatment access and improve child health in peri-urban settings, often supplanting private clinics and traditional healers as first point of care. Relative to other health service providers, caregivers valued VHTs' free, proximal services, caring attitudes, perceived treatment quality, perceived competency and protocol use, and follow-up and referral services. VHT effectiveness was perceived to be restricted by inadequate diagnostics, limited newborn care, drug stockouts and VHT member absence - factors which drove utilisation of alternative providers. Low community engagement in VHT selection, lack of referral transport and poor availability of referral services also diminished perceived effectiveness. The iCCM strategy was widely perceived to result in economic savings and other livelihood benefits.

CONCLUSIONS

In peri-urban areas, iCCM was perceived as an effective, well-utilised strategy, reflecting both VHT attributes and gaps in existing health services. Depending on health system resources and organisation, iCCM may be a useful transitional service delivery approach. Implementation in peri-urban areas should consider tailored community engagement strategies, adapted selection criteria, and assessment of population density to ensure sufficient coverage.

Research dissemination workshops: observations and implications based on an experience in Burkina Faso

Background

In Burkina Faso, malaria remains the primary cause of healthcare use, morbidity and child mortality. Therefore, efforts are needed to support the knowledge transfer and application of the results of numerous studies to better formulate and implement programs in the fight against the malaria pandemic. To this end, a 2-day dissemination workshop was held to share the most recent results produced by a multidisciplinary research team. The objective of the present study was to evaluate the workshop and the policy briefs distributed there, the effects these produced on research results use and the processes that facilitated, or not, the application of the knowledge transmitted.

Methods

A mixed-methods design was used. The data were drawn from a quantitative evaluation questionnaire completed after the workshop (n = 25/31) and qualitative interviews conducted with the researchers and various actors who attended the workshop (n = 11) and with participants in working groups (n = 40) that later analysed the policy briefs distributed at the workshop.

Results

The participants recognised the quality of the research results presented, but felt that more needed to be done to adapt the researchers’ language and improve the functioning of the workshop. The potential effects of the workshop were rather limited. Effects were mainly at two levels: individual (e.g. acquisition of new knowledge, personal awareness raising) and local (e.g. change of practice in a local non-governmental organisation). Most participants perceived the utility of the research results, but several reported that their narrow decisional power limited their ability to apply this knowledge.

Conclusions

This study showed the importance of workshops to inform key actors of research results and the need to undertake several different activities to increase the chances that the knowledge will be applied. Several recommendations are proposed to improve knowledge translation approaches in the West African context, including organising working and discussion groups, developing an action plan at the end of the workshop and offering support to participants after the workshop, among others.

Effect of interrupting free healthcare for children: Drawing lessons at the critical moment of national scale-up in Burkina Faso

With solid evidence that free healthcare increases the utilization of health services, Burkina Faso recently exempted all children under five and pregnant women from direct payment at health facilities. However, there is little insight into the capacity to maintain the gains attributable to free healthcare under routine conditions of implementation at the national scale. In particular, the repercussions of its interruption are unknown. The objective is to assess the effects of a sequence of natural interventions including the introduction, interruption and reintroduction of free healthcare on health-seeking practices and utilization of healthcare facilities by children under five. This is an embedded mixed methods study conducted in Kaya district, Burkina Faso. The quantitative component is based on a reversal longitudinal design. Pooled interrupted time-series analysis was performed to assess changes in the monthly number of visits from January 2005 to March 2015. Qualitative data were collected through in-depth interviews with health personnel and mothers to better understand the quantitative results. The results show that visits to health centres dropped immediately and significantly when free healthcare was interrupted (-146, CI_95% [-255; -37]). They increased again when free healthcare was reintroduced (+89, CI_95% [-11; 187]). Both urban and rural centres were affected. Self-medication and visits to traditional healers were reported more frequently during the withdrawal of free healthcare, and tensions between the population and health personnel increased. Implementation problems other than insufficient funding limited the coverage or intensity of free healthcare. While removing user fees could potentially improve mothers and children's health in Burkina Faso, this study shows that demand for healthcare remains highly sensitive to price changes. Gains in utilization attributable to free healthcare may vanish rapidly if user fees are reintroduced. It is essential to support an effective and sustainable implementation of this ambitious initiative.

Towards eliminating malaria in high endemic countries: the roles of community health workers and related cadres and their challenges in integrated community case management for malaria: a systematic review

BACKGROUND

Human resource for health crisis has impaired global efforts against malaria in highly endemic countries. To address this, the World Health Organization (WHO) recommended scaling-up of community health workers (CHWs) and related cadres owing to their documented success in malaria and other disease prevention and management. Evidence is inconsistent on the roles and challenges they encounter in malaria interventions. This systematic review aims to summarize evidence on roles and challenges of CHWs and related cadres in integrated community case management for malaria (iCCM).

METHODS

This systematic review retrieved evidence from PubMed, CINAHL, ISI Web of Knowledge, and WHO regional databases. Terms extracted from the Boolean phrase used for PubMed were also used in other databases. The review included studies with Randomized Control Trial, Quasi-experimental, Pre-post interventional, Longitudinal and cohort, Cross-sectional, Case study, and Secondary data analysis. Because of heterogeneity, only narrative synthesis was conducted for this review.

RESULTS

A total of 66 articles were eligible for analysis out of 1380 studies retrieved. CHWs and related cadre roles in malaria interventions included: malaria case management, prevention including health surveillance and health promotion specific to malaria. Despite their documented success, CHWs and related cadres succumb to health system challenges. These are poor and unsustainable finance for iCCM, workforce related challenges, lack of and unsustainable supply of medicines and diagnostics, lack of information and research, service delivery and leadership challenges.

CONCLUSIONS

Community health workers and related cadres had important preventive, case management and promotive roles in malaria interventions. To enable their effective integration into the health systems, the identified challenges should be addressed. They include: introducing sustainable financing on iCCM programmes, tailoring their training to address the identified gaps, improving sustainable supply chain management of malaria drugs and diagnostics, and addressing regulatory challenges in the local contexts.

Impact of contaminated household environment on stunting in children aged 12-59 months in Burkina Faso

BACKGROUND

Stunting affects 165 million children worldwide, with repercussions on their survival and development. A contaminated environment is likely to contribute to stunting: frequent faecal-oral transmission possibly causes environmental enteropathy, a chronic inflammatory disorder that may contribute to faltering growth in children. This study's objective was to assess the effect of contaminated environment on stunting in Burkina Faso, where stunting prevalence is persistently high.

METHODS

Panel study of children aged 1-5 years in Kaya. Household socioeconomic characteristics, food needs and sanitary conditions were measured once, and child growth every year (2011-2014). Using multiple correspondence analysis and 12 questions and observations on water, sanitation, hygiene behaviours, yard cleanliness and animal proximity, we constructed a 'contaminated environment' index as a proxy of faecal-oral transmission exposure. Analysis was performed using a generalised structural equation model (SEM), adjusting for repeat observations and hierarchical data.

RESULTS

Stunting (<2 SD height-for-age) prevalence was 29% among 3121 children (median (IQR) age 36 (25-48) months). Environment contamination was widespread, particularly in rural and peri-urban areas, and was associated with stunting (prevalence ratio 1.30; p=0.008), controlling for sex, age, survey year, setting, mother's education, father's occupation, household food security and wealth. This association was significant for children of all ages (1-5 years) and settings. Lower contamination and higher food security had effects of comparable magnitude.

CONCLUSIONS

Environment contamination can be at least as influential as nutritional components in the pathway to stunting. There is a rationale for including interventions to reduce environment contamination in stunting prevention programmes.

Acceptability of malaria rapid diagnostic tests administered by village health workers in Pangani District, North eastern Tanzania

Background

Malaria continues to top the list of the ten most threatening diseases to child survival in Tanzania. The country has a functional policy for appropriate case management of malaria with rapid diagnostic tests (RDTs) from hospital level all the way to dispensaries, which are the first points of healthcare services in the national referral system. However, access to these health services in Tanzania is limited, especially in rural areas. Formalization of trained village health workers (VHWs) can strengthen and extend the scope of public health services, including diagnosis and management of uncomplicated malaria in resource-constrained settings. Despite long experience with VHWs in various health interventions, Tanzania has not yet formalized its involvement in malaria case management. This study presents evidence on acceptability of RDTs used by VHWs in rural northeastern Tanzania.

Methods

A cross-sectional study using quantitative and qualitative approaches was conducted between March and May 2012 in Pangani district, northeastern Tanzania, on community perceptions, practices and acceptance of RDTs used by VHWs.

Results

Among 346 caregivers of children under 5 years old, no evidence was found of differences in awareness of HIV rapid diagnostic tests and RDTs (54 vs. 46 %, p = 0.134). Of all respondents, 92 % expressed trust in RDT results, 96 % reported readiness to accept RDTs by VHWs, while 92 % expressed willingness to contribute towards the cost of RDTs used by VHWs. Qualitative results matched positive perceptions, attitudes and acceptance of mothers towards the use of RDTs by VHWs reported in the household surveys. Appropriate training, reliable supplies, affordability and close supervision emerged as important recommendations for implementation of RDTs by VHWs.

Conclusion

RDTs implemented by VHWs are acceptable to rural communities in northeastern Tanzania. While families are willing to contribute towards costs of sustaining these services, policy decisions for scaling-up will need to consider the available and innovative lessons for successful universally accessible and acceptable services in keeping with national health policy and sustainable development goals.

High mobility, low access thwarts interventions among seasonal workers in the Greater Mekong Sub-region: lessons from the malaria containment project

BACKGROUND

During the process of malaria elimination in the Greater Mekong Sub-region, mobile and migrant populations (MMPs) have been identified as the most at-risk demographic. An important sub-group of MMPs are seasonal workers, and this paper presents an evaluation of the reach and effectiveness of interventions tailored towards this group and was carried out as part of the Containment Project from 2009-11.

METHODS

A mixed-methods study was conducted in Pailin Province in Western Cambodia. Three-hundred-and-four seasonal workers were surveyed using a structured questionnaire. Qualitative data were gathered through a total of eight focus group discussions and 14 in-depth interviews. Data triangulation of the qualitative and quantitative data was used during analysis.

RESULTS

High mobility and low access of the target population to the interventions, as well as lack of social and anthropological research that led to implementation oversights, resulted in under-exposure of seasonal workers to interventions. Consequently, their reach and impact were severely limited. Some services, particularly Mobile Malaria Workers, had the ability to significantly impact key factors, such as risky behaviours among those they did reach. Others, like Listening and Viewing Clubs and mass media campaigns, showed little impact.

CONCLUSIONS

There is potential in two of the interventions assessed, but high mobility and inadequate exposure of seasonal workers to these interventions must be considered in the development and planning of future interventions to avoid investing in low-impact activities and ensure that all interventions perform according to their maximum potential. This will be critical in order for Cambodia to achieve its aim of malaria elimination. The lessons learned from this study can be extrapolated to other areas of health care in Cambodia and other countries in order to reduce the gap between healthcare provided to MMPs, especially seasonal workers, and to the general population.

A qualitative study of health professionals' uptake and perceptions of malaria rapid diagnostic tests in Burkina Faso

Background

Since 2012, rapid diagnostic tests (RDT) for malaria have been in use nationwide in Burkina Faso. The objective is to strengthen health professionals’ diagnostic capabilities and promote good therapeutic practices. A qualitative study was conducted to learn about the adoption of this tool in the natural context of a national scale-up policy.

Methods

This study involved five health centres in two health districts. Twenty-eight individual interviews were conducted in 2013 with health professionals and members of the health district management teams. Health professionals’ RDT use and drug prescription practices were observed during 278 curative care consultations over 5 weeks.

Results

Health professionals assessed the use of RDT positively as it allowed them to reach clear and accurate diagnoses and above all to deliver appropriate, rational care. However, the introduction of RDTs did not really change their diagnostic practices or prescribing practices for artemisinin-based combination therapy (ACT). They continued to rely predominantly on symptoms in establishing their diagnoses because of doubts regarding the reliability of the tests and the occasional stockouts of RDTs experienced by the health centres. Patients with negative RDT results continued to receive anti-malarial treatments. However, the situation remains quite heterogeneous.

Conclusion

The use of RDTs points to the co-existence of official standards and different standards applied in practice. Setting up regular supervision activities provided an opportunity to observe and understand the various obstacles encountered by health professionals and to monitor how official directives are put into practice. For efficient use of RDTs and their results, health professionals need information and directives that are up-to-date and standardized.

Domestic Larval Control Practices and Malaria Prevalence among Under-Five Children in Burkina Faso

Introduction

Larval source management has contributed to malaria decline over the past years. However, little is known about the impact of larval control practices undertaken at the household level on malaria transmission.

Methods

The study was conducted in Kaya health district after the 2010 mass distribution of insecticide treated-nets and the initiation of malaria awareness campaigns in Burkina Faso. The aim was to (i) estimate the level of domestic larval control practices (cleaning of the house and its surroundings, eradication of larval sources, and elimination of hollow objects that might collect water); (ii) identify key determinants; and (iii) explore the structural relationships between these practices, participation in awareness-raising activities and mothers’ knowledge/attitudes/practices, and malaria prevalence among under-five children.

Results

Overall, 2004 households were surveyed and 1,705 under-five children were examined. Half of the mothers undertook at least one action to control larval proliferation. Mothers who had gone to school had better knowledge about malaria and were more likely to undertake domestic larval control practices. Living in highly exposed rural areas significantly decreased the odds of undertaking larval control actions. Mothers’ participation in malaria information sessions increased the adoption of vector control actions and bednet use. Malaria prevalence was statistically lower among children in households where mothers had undertaken at least one vector control action or used bed-nets. There was a 0.16 standard deviation decrease in malaria prevalence for every standard deviation increase in vector control practices. The effect of bednet use on malaria prevalence was of the same magnitude.

Conclusion

Cleaning the house and its surroundings, eradicating breeding sites, and eliminating hollow objects that might collect water play a substantial role in preventing malaria among under-five. There is a need for national malaria control programs to include or reinforce training activities for community health workers aimed at promoting domestic larval control practices.

Abolishing Fees at Health Centers in the Context of Community Case Management of Malaria: What Effects on Treatment-Seeking Practices for Febrile Children in Rural Burkina Faso?

Introduction

Burkina Faso started nationwide community case management of malaria (CCMm) in 2010. In 2011, health center user fees for children under five were abolished in some districts.

Objective

To assess the effects of concurrent implementation of CCMm and user fees abolition on treatment-seeking practices for febrile children.

Methods

This is a natural experiment conducted in the districts of Kaya (CCMm plus user fees abolition) and Zorgho (CCMm only). Registry data from 2005 to 2014 on visits for malaria were collected from all eight rural health centers in the study area. Annual household surveys were administered during malaria transmission season in 2011 and 2012 in 1,035 randomly selected rural households. Interrupted time series models were fitted for registry data and Fine and Gray’s competing risks models for survey data.

Results

User fees abolition in Kaya significantly increased health center use by eligible children with malaria (incidence rate ratio for intercept change = 2.1, p <0.001). In 2011, in Kaya, likelihood of health center use for febrile children was three times higher and CHW use three times lower when caregivers knew services were free. Among the 421 children with fever in 2012, the delay before visiting a health center was significantly shorter in Kaya than in Zorgho (1.46 versus 1.79 days, p <0.05). Likelihood of visiting a health center on the first day of fever among households <2.5km or <5 km from a health center was two and three times higher in Kaya than in Zorgho, respectively (p <0.001).

Conclusions

User fees abolition reduced visit delay for febrile children living close to health centers. It also increased demand for and use of health center for children with malaria. Concurrently, demand for CHWs’ services diminished. User fees abolition and CCMm should be coordinated to maximize prompt access to treatment in rural areas.
