Parents' perceptions, attitudes and acceptability of treatment of childhood malaria with artemisinin combination therapies in ghana

Insights into the Affordable Medicines Facility-malaria in Ghana: the role of caregivers and licensed chemical sellers in four regions

Background

The Affordable Medicine Facility-malaria (AMFm) was an innovative global financing mechanism for the provision of quality-assured artemisinin-based combination therapy (ACT) across both the private and public health sectors in eight countries in sub-Saharan Africa. This study evaluated the effectiveness of AMFm subsidies in increasing access to ACT in Ghana and documented malaria management practices at the household and community levels during the implementation of the AMFm.

Methods

This study, conducted in four regions in Ghana between January, 2011 to December, 2012, employed cross-sectional mixed-methods design that included qualitative and quantitative elements, specifically household surveys, focus group discussions (FGD) and in-depth interviews.

Results

The study indicated high ACT availability, adequate provider knowledge and reasonably low quality-assured ACT use in the study areas, all of which are a reflection of a high market share of ACT in these hard-to-reach areas of the country. Adequate recognition of childhood malaria symptoms by licensed chemical seller (LCS) attendants was observed. A preference by caregivers for LCS over health facilities for seeking treatment solutions to childhood malaria was found.

Conclusions

Artemisinin-based combination therapy with the AMFm logo was accessible and affordable for most people seeking treatment from health facilities and LCS shops in rural areas. Caregivers and LCS were seen to play key roles in the health of the community especially with children under 5 years of age.

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.

Adherence to Artemisinin-Based Combination Therapy for the Treatment of Uncomplicated Malaria: A Systematic Review and Meta-Analysis

Adherence to artemisinin-based combination therapy (ACT) is not clearly defined. This meta-analysis determines the prevalence and predictors of adherence to ACT. Twenty-five studies and six substudies met the inclusion criteria. The prevalence of ACT adherence in the public sector was significantly higher compared to retail sector (76% and 45%, resp., P < 0.0001). However, ACT adherence was similar across different ACT dosing regimens and formulations. In metaregression analysis prevalence estimates of adherence significantly decrease with increasing year of study publication (P = 0.046). Factors found to be significant predictors of ACT adherence were years of education ≥ 7 {odds ratio (OR) (95% CI) = 1.63 (1.05–2.53)}, higher income {2.0 (1.35–2.98)}, fatty food {4.6 (2.49–8.50)}, exact number of pills dispensed {4.09 (1.60–10.7)}, and belief in traditional medication for malaria {0.09 (0.01–0.78)}. The accuracy of pooled estimates could be limited by publication bias, and differing methods and thresholds of assessing adherence. To improve ACT adherence, educational programs to increase awareness and understanding of ACT dosing regimen are interventions urgently needed. Patients and caregivers should be provided with an adequate explanation at the time of prescribing and/or dispensing ACT.

The effects of co-infection with human parvovirus B19 and Plasmodium falciparum on type and degree of anaemia in Ghanaian children

OBJECTIVE

To determin the extent to which parvovirus B19 (B19V) and co-infection of B19V and malaria contribute to risk of anaemia in children.

METHODS

B19V DNA and malaria parasites were screened for 234 children at the PML Children's Hospital in Accra. The role of B19V and co-infection with B19V and malaria in anaemia was evaluated by analysing full blood cell counts, malaria and B19V DNA results from these children.

RESULTS

The prevalence of B19V, malaria and co-infection with B19V and malaria was 4.7%, 41.9% and 2.6%, respectively. Malaria posed a greater risk in the development of mild anaemia compared to severe anaemia (OR=5.28 vrs 3.15) whereas B19V posed a higher risk in the development of severe anaemia compared to mild anaemia (OR=4.07 vrs 1.00) from a non-anaemic child. Persons with co-infection with B19V and malaria had 2.23 times the risk (95% CI=0.40-12.54) of developing severe anaemia should they already have a mild anaemia. The degree of anaemia was about three times affected by co-infection (Pillai's trace=0.551, P=0.001) as was affected by malaria alone (Pillai's trace=0.185, P=0.001). B19V alone did not significantly affect the development of anaemia in a non-anaemic child. Microcytic anaemia was associated with B19V and co-infection with B19V and malaria more than normocytic normochromic anaemia.

CONCLUSIONS

B19V was associated with malaria in cases of severe anaemia. The association posed a significant risk for exacerbation of anaemia in mild anaemic children. B19V and co-infection with B19V and malaria may be associated with microcytic anaemia rather than normocytic normochromic anaemia as seen in cases of B19V infection among persons with red cell abnormalities.

Treating uncomplicated malaria in children: comparing artemisinin-based combination therapies

PURPOSE OF REVIEW

In response to increased resistance to conventional drugs, the WHO is promoting artemisinin-based combination therapy (ACT) for treating uncomplicated malaria. The objective of this report is to review the available evidence on the efficacy and effectiveness, acceptability, and deployment of ACT in resource-limited settings with a focus on sub-Saharan Africa.

RECENT FINDINGS

ACTs are very effective in the treatment of uncomplicated Plasmodium falciparum malaria in children. ACTs are relatively safe and tolerable with no reported resistance in sub-Saharan Africa despite indications of delayed clearance of infections in south-east Asia. The major challenges to the widespread use of ACT include its high cost, availability, and inefficient delivery due to, among other things, weak healthcare systems.

SUMMARY

ACTs are an essential tool in the fight to control and eliminate malaria. They are currently the most effective drugs against P. falciparum malaria. They should be deployed through programs that address availability, cost, adherence, and quality assurance. Initiatives including home-based management of malaria, improving public sector procurement and supply chains, and reducing private sector pricing should make ACTs more accessible for sub-Saharan African children who bear the brunt of the burden of malarial disease.
