Intermittent preventive treatment of malaria in children: a qualitative study of community perceptions and recommendations in Burkina Faso and Mali

Contextual Factors to Improve Implementation of Malaria Chemoprevention in Children: A Systematic Review

Malaria remains a leading cause of childhood morbidity and mortality in sub-Saharan Africa, particularly among children under 5 years of age. To help address this challenge, the WHO recommends chemoprevention for certain populations. For children and infants, the WHO recommends seasonal malaria chemoprevention (SMC), perennial malaria chemoprevention (PMC; formerly intermittent preventive treatment in infants [IPTi]), and, more recently, intermittent preventive treatment in school children (IPTsc). This review describes the contextual factors, including feasibility, acceptability, health equity, financial considerations, and values and preferences, that impact implementation of these strategies. A systematic search was conducted on July 5, 2022, and repeated April 13, 2023, to identify relevant literature. Two reviewers independently screened titles for eligibility, extracted data from eligible articles, and identified and summarized themes. Of 6,295 unique titles identified, 65 were included. The most frequently evaluated strategy was SMC (n = 40), followed by IPTi (n = 18) and then IPTsc (n = 6). Overall, these strategies were highly acceptable, although with IPTsc, there were community concerns with providing drugs to girls of reproductive age and the use of nonmedical staff for drug distribution. For SMC, door-to-door delivery resulted in higher coverage, improved caregiver acceptance, and reduced cost. Lower adherence was noted when caregivers were charged with giving doses 2 and 3 unsupervised. For SMC and IPTi, travel distances and inclement weather limited accessibility. Sensitization and caregiver education efforts, retention of high-quality drug distributors, and improved transportation were key to improving coverage. Additional research is needed to understand the role of community values and preferences in chemoprevention implementation.

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.

Acceptability and feasibility of malaria prophylaxis for forest goers: findings from a qualitative study in Cambodia

BACKGROUND

In the Greater Mekong Subregion, adults are at highest risk for malaria, particularly those who visit forests. The absence of effective vector control strategies and limited periods of exposure during forest visits suggest that chemoprophylaxis could be an appropriate strategy to protect forest goers against malaria.

METHODS

Alongside a clinical trial of anti-malarial chemoprophylaxis in northern Cambodia, qualitative research was conducted, including in-depth interviews and observation, to explore the acceptability of malaria prophylaxis for forest goers, the implementation opportunities, and challenges of this strategy.

RESULTS

Prophylaxis with artemether-lumefantrine for forest goers was found to be acceptable under trial conditions. Three factors played a major role: the community's awareness and perception of the effectiveness of prophylaxis, their trust in the provider, and malaria as a local health concern. The findings highlight how uptake and adherence to prophylaxis are influenced by the perceived balance between benefits and burden of anti-malarials which are modulated by the seasonality of forest visits and its influence on malaria risk.

CONCLUSIONS

The implementation of anti-malarial prophylaxis needs to consider how the preventive medication can be incorporated into existing vector-control measures, malaria testing and treatment services. The next step in the roll out of anti-malarial prophylaxis for forest visitors will require support from local health workers.

Assessment of the Feasibility, Acceptability, and Impact of Implementing Seasonal Malaria Chemoprevention in Nampula Province, Mozambique: Protocol for a Hybrid Effectiveness-Implementation Study

Background

Malaria is a significant cause of morbidity and mortality in children aged under 5 years in Mozambique. The World Health Organization recommends seasonal malaria chemoprevention (SMC), the administration of four monthly courses of sulfadoxine-pyrimethamine (SP) and amodiaquine (AQ), to children aged 3-59 months during rainy season. However, as resistance to SP is widespread in East and Southern Africa, SMC has so far only been implemented across the Sahel in West Africa.

Objective

This protocol describes the first phase of a pilot project that aims to assess the protective effect of SP and AQ when used for SMC and investigate the levels of molecular markers of resistance of Plasmodium falciparum to antimalarial medicines in the study districts. In addition, it is important to understand whether SMC is a feasible and acceptable intervention in the context of Nampula Province, Mozambique.

Methods

This study will adopt a hybrid effectiveness-implementation design to conduct a mixed methods evaluation with six objectives: a molecular marker study, a nonrandomized controlled trial, an analysis of reported malaria morbidity indicators, a documentation exercise of the contextual SMC adaptation, an acceptability and feasibility assessment, and a coverage and quality assessment.

Results

Ethical approval for this study was granted by the Mozambican Ministry of Health National Bioethics Committee on September 15, 2020. Data collection began in October 2020, and data analysis is expected to be completed by August 2021.

Conclusions

This research will make a unique contribution to our understanding of whether the combination of SP and AQ, when used for SMC, can confer a protective effect against malaria in children aged 3-59 months in a region where malaria transmission is seasonal and SP resistance is expected to be high. If the project is successful, subsequent phases are expected to provide a more comprehensive assessment of the effectiveness and sustainability of SMCs.

End-user perspectives on preventive antimalarials: A review of qualitative research

Antimalarials have been administered widely to prevent clinical malaria and researchers have explored how end-users' perspectives influence uptake and adherence. Drawing on a systematic search, this review aims to synthesise qualitative research on end-user perceptions of antimalarials for disease prevention. Searches were undertaken in PubMed and ISI Web of Knowledge. After applying exclusion criteria, identified sources underwent thematic analysis. Identified sources were published between 2000 and 2020 and drew on studies undertaken across Africa, Asia, Europe, Oceania and America. The sources revealed end-user concerns about the potential benefits and harms of preventive treatment that are entwined with broader understandings of the disease, the intervention, its implementation, accompanying information, and how it is embedded in wider healthcare and social relationships. The implications for antimalarials as preventive therapy encompass the need to build trust, including interpersonal trust, engage diverse stakeholders and to address broader health and wellbeing concerns during implementation.

Are We Using the Right Approach to Change Newborn Care Practices in the Community? Qualitative Evidence From Ethiopia and Northern Nigeria

In Ethiopia, high community-level exposure to consistent messages and the perceptions of community health workers and relationships with them drove newborn care behavior change. In Nigeria, exposure to messages was limited, community health workers were less trusted, and behavior change was reported less frequently.

Changing behaviors is usually a core component of the role of community health workers (CHWs), but little is known about the mechanisms through which they change behavior. We collected qualitative data from 8 sites in Ethiopia and northern Nigeria where CHWs were active to understand how they change newborn care behaviors. In each country, we conducted 12 narrative interviews and 12–13 in-depth interviews with recent mothers and 4 focus group discussions each with mothers, fathers, grandmothers, and CHWs. We identified 2 key mechanisms of behavior change. The first was linked to the frequency and consistency of hearing messages that led to a perception that change had occurred in community-wide behaviors, collective beliefs, and social expectations. The second was linked to trust in the CHW, obligation, and hierarchy. We found little evidence that constructs that often inform the design of counseling approaches, such as knowledge of causality and perceived risks and benefits, were mechanisms of change.

Community facilitators and barriers to a successful implementation of mass drug administration and indoor residual spraying for malaria prevention in Uganda: a qualitative study

Background

There is growing interest to add mass drug administration (MDA) to the already existing malaria prevention strategies, such as indoor residual spraying (IRS). However, successful MDA and IRS requires high population-wide coverage, emphasizing the importance of community acceptance. This study’s objectives were to identify community-level facilitators and barriers during the implementation of both MDA and IRS in communities with high malaria transmission intensity.

Methods

This was a qualitative study conducted in two sub-counties in Katakwi district. Kapujan sub-county residents received two rounds of IRS and MDA while Toroma sub-county residents received two rounds of IRS only. Key informant interviews and focus group discussions were conducted with key influential district and sub-county personnel and community members. Data were analysed using thematic analysis. Transcripts and interview notes from the in-depth interviews were analysed using a coding scheme developed from pre-defined topics together with themes emerging from the data. The Nvivo software program was used to aggregate the data by codes and to present study findings.

Results

Overall, 14 key informants were interviewed: 4 from Katakwi district and 5 each from Kapujan and Toroma sub-counties. Five focus group discussions were conducted: 4 with community members (men and women), 2 in each sub-county and one with medical staff of Toroma health centre IV. Important themes for consideration raised by the respondents include community sensitization, conducting implementation during the low activity dry season, involvement of government and local leadership, use of the competent locally composed team, community knowledge of malaria effects and consequences, combining interventions and evidence of malaria reduction from interventions. Potential barriers such as spreading of misinformation regarding interventions, the strong unpleasant smell from Actellic and inadequate duration of engagement with the community should be taken into consideration.

Conclusion

This study documents important community engagement strategies that need to be considered when implementing malaria MDA in combination with IRS, for malaria prevention in such settings. This information is useful for malaria programmes, especially during the design and implementation of such community level interventions.

Implementation, coverage and equity of large-scale door-to-door delivery of Seasonal Malaria Chemoprevention (SMC) to children under 10 in Senegal

SMC has been introduced widely in the Sahel since its recommendation by WHO in 2012. This study, which provided evidence of feasibility that supported the recommendation, included school-age and pre-school children. School-age children were not included in the 2012 recommendation but bear an increasing proportion of cases. In 2006, consultations with health-staff were held to choose delivery methods. The preferred approach, door-to-door with the first daily-dose supervised by a community-health-worker (CHW), was piloted and subsequently evaluated on a large-scale in under-5’s in 2008 and then in under-10’s 2009–2010. Coverage was higher among school-age children (96%(95%CI 94%,98%) received three treatments in 2010) than among under 5’s (90%(86%,94%)). SMC was more equitable than LLINs (odds-ratio for increase in coverage for a one-level rise in socioeconomic-ranking (a 5-point scale), was 1.1 (0.95,1.2) in 2009, compared with OR 1.3 (1.2,1.5) for sleeping under an LLIN. Effective communication was important in achieving high levels of uptake. Continued training and supervision were needed to ensure CHWs adhered to treatment guidelines. SMC door-to-door can, if carefully supervised, achieve high equitable coverage and high-quality delivery. SMC programmes can be adapted to include school-age children, a neglected group that bears a substantial burden of malaria.

Evaluation of the implementation fidelity of the seasonal malaria chemoprevention intervention in Kaya health district, Burkina Faso

BACKGROUND

Burkina Faso implemented the seasonal malaria chemoprevention (SMC) in 2014 in seven pilot health districts, following the new recommendation by the WHO in 2012 for the prevention of the disease in children under five years old, for areas of highly seasonal malaria transmission.The objective of this study was to assess the implementation fidelity of the seasonal malaria chemoprevention strategy in one of the districts, Kaya Health District.

METHODOLOGY

We conducted a case study, with a quantitative and qualitative mixed methods. Data were collected after two campaigns of implementation of the intervention, in 2014 and 2015, through a review of specific documents of SMC intervention, and individual interview with key informants (n = 21) involved at various levels in the implementation of the strategy and a household survey with the parents (n = 284) of eligible children for the SMC strategy in 2015 in the Kaya health district. The analysis framework focused on the fidelity of the intervention's content, its coverage, and its schedule, as well as the potential moderating factors, using the model proposed by Hasson, originally from Carroll.

RESULTS

All components of the intervention were implemented. Villages and sectors were covered at 100%. In terms of intervention doses received, less than one-third of eligible children (32.3%) received the recommended four doses in 2015. Implementation of the strategy faced some difficulties due to insufficient training of community distributors, inadequate supply of inputs and insufficient financial resources for remuneration, advocacy and supervision, but also because of the contextual constraints due to the rainy season. Moreover, an interaction between the different moderating factors, influencing the degree of implementation of the strategy was noted.

CONCLUSION

Taking into account the moderating factors of the implementation is necessary for achieving the highest possible degree of implementation fidelity and then, reach the expected beneficial effects.

Seasonal malaria chemoprevention: successes and missed opportunities

Seasonal malaria chemoprevention (SMC) was recommended in 2012 for young children in the Sahel during the peak malaria transmission season. Children are given a single dose of sulfadoxine/pyrimethamine combined with a 3-day course of amodiaquine, once a month for up to 4 months. Roll-out and scale-up of SMC has been impressive, with 12 million children receiving the intervention in 2016. There is evidence of its overall benefit in routine implementation settings, and a meta-analysis of clinical trial data showed a 75% decrease in clinical malaria compared to placebo. SMC is not free of shortcomings. Its target zone includes many hard-to-reach areas, both because of poor infrastructure and because of political instability. Treatment adherence to a 3-day course of preventive treatment has not been fully documented, and could prove challenging. As SMC is scaled up, integration into a broader, community-based paradigm which includes other preventive and curative activities may prove beneficial, both for health systems and for recipients.

Facilitators and Barriers to Uptake of an Extended Seasonal Malaria Chemoprevention Programme in Ghana: A Qualitative Study of Caregivers and Community Health Workers

Background

Seasonal Malaria Chemoprevention (SMC) is currently recommended for children under five in areas where malaria transmission is highly seasonal. We explored children’s caregivers’ and community health workers’ (CHWs) responses to an extended 5-month SMC programme.

Methods

Thirteen in-depth interviews and eight focus group discussions explored optimal and suboptimal ‘uptake’ of SMC to examine facilitators and barriers to caregivers’ uptake.

Results

There did not appear to be major differences between caregivers of children with optimal and sub-optimal SMC uptake in terms of their knowledge of malaria, their perceptions of the effect of SMC on a child’s health, nor their understanding of chemoprevention. Caregivers experienced difficulty in prioritising SMC for well children, perceiving medication being for treatment rather than prevention. Prior to the study, caregivers had become accustomed to rapid diagnostic testing (RDT) for malaria, and therefore blood testing for malaria during the baseline survey at the start of the SMC programme may have positively influenced uptake. Facilitators of uptake included caregivers’ trust in and respect for administrators of SMC (including CHWs), access to medication and supportive (family) networks. Barriers to uptake related to poor communication of timings of community gatherings, travel distances, absence during SMC home deliveries, and limited demand for SMC due to lack of previous experience. Future delivery of SMC by trained CHWs would be acceptable to caregivers.

Conclusion

A combination of caregivers’ physical access to SMC medication, the drug regimen, trust in the medical profession and perceived norms around malaria prevention all likely influenced caregivers’ level of uptake. SMC programmes need to consider: 1) developing supportive, accessible and flexible modes of drug administration including home delivery and village community kiosks; 2) improving demand for preventive medication including the harnessing of learnt trust; and 3) developing community-based networks for users to support optimal uptake of SMC.

The role of community participation in intermittent preventive treatment of childhood malaria in southeastern Ghana

BACKGROUND

Malaria remains a major cause of morbidity and mortality in Ghana. Very little attention was paid to community participation in malaria control in the past and this has affected most of the desired outcomes. The recent recognition of the importance of community participation in malaria control had informed the implementation of Intermittent Preventive Treatment of Childhood Malaria (IPTc). The intervention was implemented in the Shime sub-district of the Keta District in Ghana and this paper reports the evaluation of the community involvement aspect of the project.

METHOD

Semi-structured questionnaire were administered to 105 randomly selected caregivers. A focus group discussion was organized for nine Community Assistants (CAs) and 16 in-depth interviews were conducted with opinion leaders. The tools were used to investigate community attitudes towards, level of awareness and acceptance of the intervention. The benefits of the project and the preferred mode of drug delivery were also investigated.

RESULTS

Findings indicated that, the people were aware of the project in their communities. They showed high level of participation and have accepted the intervention as their own. There was a reported reduction in hospital attendance from 52.4% to 6.7%, which led to perceived savings for caregivers. The people preferred that community members deliver the drugs because they are more approachable, caring and sensitive to their health needs than the nurses.

CONCLUSION

The approach adopted by entrusting the intervention into the hands of the community members by allowing them to select their own CAs coupled with the observation of necessary community protocols had led to high level of participation, acceptance and successful outcome of the intervention.

What do community health workers have to say about their work, and how can this inform improved programme design? A case study with CHWs within Kenya

BACKGROUND

Community health workers (CHWs) are used increasingly in the world to address shortages of health workers and the lack of a pervasive national health system. However, while their role is often described at a policy level, it is not clear how these ideals are instantiated in practice, how best to support this work, or how the work is interpreted by local actors. CHWs are often spoken about or spoken for, but there is little evidence of CHWs' own characterisation of their practice, which raises questions for global health advocates regarding power and participation in CHW programmes. This paper addresses this issue.

DESIGN

A case study approach was undertaken in a series of four steps. Firstly, groups of CHWs from two communities met and reported what their daily work consisted of. Secondly, individual CHWs were interviewed so that they could provide fuller, more detailed accounts of their work and experiences; in addition, community health extension workers and community health committee members were interviewed, to provide alternative perspectives. Thirdly, notes and observations were taken in community meetings and monthly meetings. The data were then analysed thematically, creating an account of how CHWs describe their own work, and the tensions and challenges that they face.

RESULTS

The thematic analysis of the interview data explored the structure of CHW's work, in terms of the frequency and range of visits, activities undertaken during visits (monitoring, referral, etc.) and the wider context of their work (links to the community and health service, limited training, coordination and mutual support through action and discussion days, etc.), and provided an opportunity for CHWs to explain their motivations, concerns and how they understood their role. The importance of these findings as a contribution to the field is evidenced by the depth and detail of their descriptive power. One important aspect of this is that CHWs' accounts of both successes and challenges involved material elements: leaky tins and dishracks evidenced successful health interventions, whilst bicycles, empty first aid kits and recruiting stretcher bearers evidenced the difficulties of resourcing and geography they are required to overcome.

CONCLUSION

The way that these CHWs described their work was as healthcare generalists, working to serve their community and to integrate it with the official health system. Their work involves referrals, monitoring, reporting and educational interactions. Whilst they face problems with resources and training, their accounts show that they respond to this in creative ways, working within established systems of community power and formal authority to achieve their goals, rather than falling into a 'deficit' position that requires remedial external intervention. Their work is widely appreciated, although some households do resist their interventions, and figures of authority sometimes question their manner and expertise. The material challenges that they face have both practical and community aspects, since coping with scarcity brings community members together. The implication of this is that programmes co-designed with CHWs will be easier to implement because of their relevance to their practices and experiences, whereas those that assume a deficit model or seek to use CHWs as an instrument to implement external priorities are likely to disrupt their work.

Factors likely to affect community acceptance of a malaria vaccine in two districts of Ghana: a qualitative study

Malaria is a leading cause of morbidity and mortality among children in Ghana. As part of the effort to inform local and national decision-making in preparation for possible malaria vaccine introduction, this qualitative study explored community-level factors that could affect vaccine acceptance in Ghana and provides recommendations for a health communications strategy. The study was conducted in two purposively selected districts: the Ashanti and Upper East Regions. A total of 25 focus group discussions, 107 in-depth interviews, and 21 semi-structured observations at Child Welfare Clinics were conducted. Malaria was acknowledged to be one of the most common health problems among children. While mosquitoes were linked to the cause and bed nets were considered to be the main preventive method, participants acknowledged that no single measure prevented malaria. The communities highly valued vaccines and cited vaccination as the main motivation for taking children to Child Welfare Clinics. Nevertheless, knowledge of specific vaccines and what they do was limited. While communities accepted the idea of minor vaccine side effects, other side effects perceived to be more serious could deter families from taking children for vaccination, especially during vaccination campaigns. Attendance at Child Welfare Clinics after age nine months was limited. Observations at clinics revealed that while two different opportunities for counseling were offered, little attention was given to addressing mothers’ specific concerns and to answering questions related to child immunization. Positive community attitudes toward vaccines and the understanding that malaria prevention requires a comprehensive approach would support the introduction of a malaria vaccine. These attitudes are bolstered by a well-established child welfare program and the availability in Ghana of active, flexible structures for conveying health information to communities. At the same time, it would be important to improve the quality of Child Welfare Clinic services, particularly in relation to communication around vaccination.

Traditional medicine practitioners' knowledge and views on treatment of pregnant women in three regions of Mali

BACKGROUND

Despite the widespread use of medicinal plants in Mali, knowledge about how traditional practitioners (TPs) treat pregnant and lactating women is lacking.

AIM OF THE STUDY

The aim of this study was to investigate how traditional practitioners in Mali treat common diseases and ailments during pregnancy.

METHODS

Data was collected through structured interviews of traditional practitioners in one urban (Bamako) and two rural areas (Siby and Dioila) in Mali. The TPs were interviewed about how they treat common diseases and ailments during pregnancy. They were also asked to name harmful plants in pregnancy and plants that could affect breast milk production. In addition, we asked about nine specific medicinal plants commonly used in Mali; Opilia amentacea (syn. Opilia celtidifolia), Ximenia americana, Cola cordifolia, Combretum glutinosum, Parkia biglobosa, Trichilia emetica, Combretum micranthum, Lippia chevalieri and Vepris heterophylla.

RESULTS

A total of 72 traditional practitioners (64% women, age: 34 to 90 years) were interviewed during an eight week period October 2011 to December 2011. They treated between 1 and 30 pregnant women with medicinal plants per months. We found a relatively high consensus for treatment of pregnant women with common diseases and ailments like nausea and dermatitis. The highest informer consensus was found for the treatment of malaria during pregnancy. TPs generally recommended pregnant women to avoid medicinal plants with bitter tastes like stem and root bark of Khaya senegalensis and Opilia amentacea (syn. Opilia celtidifolia). TPs distinguished between oral (potentially unsafe) and dermal use (safe) of Opilia amentacea (syn. Opilia celtidifolia). Cola cordifolia was used to facilitate labor.

CONCLUSION

Experience and knowledge about treatment of pregnant women with medicinal plants was broad among the traditional practitioners in the three investigated regions in Mali. Collaborating with traditional practitioners on the safe use of medicinal plants in pregnancy may promote safer pregnancies and better health for mothers and their unborn infants in Mali.

Selective intermittent preventive treatment of vivax malaria: reduction of malaria incidence in an open cohort study in brazilian Amazon

In children, the Intermittent Preventive Treatment (IPTc), currently called Seasonal Malaria Chemoprevention (SMC), was considered effective on malaria control due to the reduction of its incidence in Papua New Guinea and in some areas with seasonal malaria in Africa. However, the IPT has not been indicated because of its association with drug resistance and for hindering natural immunity development. Thus, we evaluated the alternative IPT impact on malaria incidence in three riverside communities on Madeira River, in the municipality of Porto Velho, RO. We denominate this scheme Selective Intermittent Preventive Treatment (SIPT). The SIPT consists in a weekly dose of two 150 mg chloroquine tablets for 12 weeks, for adults, and an equivalent dose for children, after complete supervised treatment for P. vivax infection. This scheme is recommend by Brazilian Health Ministry to avoid frequent relapses. The clinic parasitological and epidemiological surveillance showed a significant reduction on vivax malaria incidence. The results showed a reduction on relapses and recurrence of malaria after SIPT implementation. The SIPT can be effective on vivax malaria control in localities with high transmission risk in the Brazilian Amazon.
