Evaluating COVID-19-Related Disruptions to Effective Malaria Case Management in 2020-2021 and Its Potential Effects on Malaria Burden in Sub-Saharan Africa.

The COVID-19 pandemic has led to far-reaching disruptions to health systems, including preventative and curative services for malaria. The aim of this study was to estimate the magnitude of disruptions in malaria case management in sub-Saharan Africa and their impact on malaria burden during the COVID-19 pandemic. We used survey data collected by the World Health Organization, in which individual country stakeholders reported on the extent of disruptions to malaria diagnosis and treatment. The relative disruption values were then applied to estimates of antimalarial treatment rates and used as inputs to an established spatiotemporal Bayesian geostatistical framework to generate annual malaria burden estimates with case management disruptions. This enabled an estimation of the additional malaria burden attributable to pandemic-related impacts on treatment rates in 2020 and 2021. Our analysis found that disruptions in access to antimalarial treatment in sub-Saharan Africa likely resulted in approximately 5.9 (4.4-7.2 95% CI) million more malaria cases and 76 (20-132) thousand additional deaths in the 2020-2021 period within the study region, equivalent to approximately 1.2% (0.3-2.1 95% CI) greater clinical incidence of malaria and 8.1% (2.1-14.1 95% CI) greater malaria mortality than expected in the absence of the disruptions to malaria case management. The available evidence suggests that access to antimalarials was disrupted to a significant degree and should be considered an area of focus to avoid further escalations in malaria morbidity and mortality. The results from this analysis were used to estimate cases and deaths in the World Malaria Report 2022 during the pandemic years.

Feasibility and Acceptability of a Strategy Deploying Multiple First-Line Artemisinin-Based Combination Therapies for Uncomplicated Malaria in the Health District of Kaya, Burkina Faso.

(1) Background: Effective malaria case management relies on World Health Organization (WHO) recommended artemisinin-based combination therapies (ACTs), but partial resistance to artemisinin has emerged and is spreading, threatening malaria control and elimination efforts. The strategy of deploying multiple first-line therapies (MFT) may help mitigate this threat and extend the therapeutic life of current ACTs. (2) Methods: A district-wide pilot quasi-experimental study was conducted, deploying three different ACTs at the public health facility (PHF) level for uncomplicated malaria treatment from December 2019 to December 2020 in the health district (HD) of Kaya, Burkina Faso. Mixed methods, including household and health facility-based quantitative and qualitative surveys, were used to evaluate the pilot programme. (3) Results: A total of 2008 suspected malaria patients were surveyed at PHFs, of which 79.1% were tested by rapid diagnostic test (RDT) with 65.5% positivity rate. In total, 86.1% of the confirmed cases received the appropriate ACT according to the MFT strategy. The adherence level did not differ by study segment (p = 0.19). Overall, the compliance level of health workers (HWs) with MFT strategy was 72.7% (95% CI: 69.7-75.5). The odds of using PHF as the first source of care increased after the intervention (aOR = 1.6; 95% CI, 1.3-1.9), and the reported adherence to the 3-day treatment regimen was 82.1%; (95% CI: 79.6-84.3). Qualitative results showed a high acceptance of the MFT strategy with positive opinions from all stakeholders. (4) Conclusions: Implementing an MFT strategy is operationally feasible and acceptable by stakeholders in the health systems in Burkina Faso. This study provides evidence to support the simultaneous use of multiple first-line artemisinin combination therapies in malaria-endemic countries such as Burkina Faso.

The influence of training outcome and competency on effective utilization of malaria microscopy result amongst health professionals in South Eastern Nigeria

Malaria diagnosis in Nigeria mostly relied on clinical manifestations until 2011, when the government issued a policy requiring parasitological confirmation of all suspected malaria cases prior to treatment. Poor usage of malaria test results in health care delivery is one of the possible causes of over-diagnosis and over-treatment of malaria in Nigeria. This study demonstrated the influence of in-service training on malaria microscopy amongst medical laboratory scientists on the utilization of malaria microscopy results in a selected Government Health Facility in Nigeria. In 2014, a baseline study was conducted, and a follow-up study was conducted in which end users of laboratory results in selected secondary health facilities were given a pre-tested questionnaire on perception and utilization of malaria microscopy results by health care providers in malaria case management. Medical laboratory scientists working in these selected facilities were then given basic malaria microscopy training in accordance with the World Health Organization's (WHO) basic microscopy training manual. The training was followed by a supporting supervision visit to the Medical Laboratories, where other factors that can skew microscopy results, such as the need for special equipment, were addressed during the basic and refresher training. We conducted paired t-test to determine statistically significant differences between pre-test and post-test results at 0.05 significance level and ANOVA to determine if there were differences in knowledge level before and after the training and between the basic and refresher training. The study demonstrates a significant improvement in both the basic and refresher training mean parasite detection pre-and post-tests scores from 56.3% (95% CI 53.6-58.8%) to 77.7% (95% CI 74.4-80.2%) and 76.7 (95% CI 74.2-79.2%) to 91.2% (95% CI 88.3-94.1%)(P< 0.001). When comparing the rate of utilization of malaria results from trained Medical Laboratory Scientists to the baseline and follow-up studies, as well as the assessment of facilities' malaria test requests and utilization pattern during the study period, there was a substantial difference (p< 0.001). The increase in utilization of malaria microscopy result for effective case management of malaria in the study area was influenced by training outcome and competency of Medical Laboratory Scientists. Key words: Malaria results, microscopy T raining, medical Laboratory scientists, health care providers.

Community and healthcare providers\u2019 perceptions of quality of private sector outpatient malaria care in North-western Ethiopia: a qualitative study

BackgroundMalaria is one of the most important public health problems in Ethiopia contributing to significant patient morbidity and mortality. Prompt diagnosis and effective malaria case management through public, private and community health facilities has been one of the key malaria prevention, control and elimination strategies. The objective of this study was to evaluate adult malaria patients and healthcare providers’ perception of the quality of malaria management at private sector outpatient facilities.MethodsAn exploratory, descriptive, contextual and qualitative research methodology was conducted with 101 participants (33 in-depth interviews (INIs) and ten focus group discussions (FGDs) with 68 participants). All interview and focus group discussions were audio recorded, transcribed verbatim and analysed, using eight steps of Tesch.ResultsDuring data analysis a single theme, two categories and six sub-categories emerged, namely (1) perceived quality of malaria management at outpatient facilities; (a) essential resources; (a1) safe outpatient services; (a2) anti-malarial drugs and supplies; (a3) health workers; (b) factors influencing service utilization; (b1) physical accessibility; (b2) “art of care’’; and (b3) efficient malaria diagnosis and treatment services. Both FGDs and INIs participants had a positive perception of the quality of malaria outpatient services at private health facilities. The positive perceptions include safe and clean facility; availability of supplies and comprehensive services; convenient working hours; short waiting hours and motivated, competent and compassionate health workers. However, some participants raised their safety concerns due to perceived poor infection control practices, small working areas, interruption of anti-malarial supplies and inefficient malaria diagnosis and treatment services.ConclusionBoth community members and healthcare providers had more positive perceptions towards outpatient malaria services offered at private health facilities. However, positive behaviour must be maintained and concerns must be dealt with by enhancing functional public private partnership for malaria care services to improve private sector malaria case management; build the service providers’ capacity; ensure uninterrupted anti-malarial supplies and empower the community with early health-seeking behaviour.

Challenges affecting prompt access to adequate uncomplicated malaria case management in children in rural primary health facilities in Chikhwawa Malawi

BackgroundReducing the burden of malaria highly depends on access to prompt and effective malaria diagnosis and treatment. The aim of this study was to identify challenges affecting prompt access to effective uncomplicated malaria case management in children below 10 years old in rural primary health care facilities in Malawi.MethodsA cross sectional health facility survey was conducted in six primary health facilities in Chikhwawa district, Malawi. Officers-in-charge of health facilities were interviewed on availability of staff, supplies and drugs. All consecutive children presenting at the facility with fever or suspected malaria, aged 6 months to 10 years old, were eligible to participate in exit interviews. Exit interviews with participants’ guardians assessed duration of illness, demographic information and distance travelled. Adherence to recommended malaria case management guidelines included performing malaria rapid diagnostic tests (mRDTs) in children with fever or suspected malaria and prescribing recommended weight-based dose of artemether-lumefantrine (AL) when mRDT was positive. Multivariate logistic regression was used to determine factors associated with prompt care seeking within 24 h of onset of illness.ResultsHealth facilities were staffed by at least two health workers. Of 265 children screened, nine were excluded due to severe illness. Twenty-one percent of children presenting at a health facility with fever were not tested for malaria. Adherence to positive and negative mRDT results for those tested was 99.4, 95% CI [98.1–100] and 97, 95% CI [88.9–100], respectively. AL was prescribed as recommended by weight in 152 children (92.2%). Temporary stock outs of AL occurred in five of six facilities. In total, 146 (57, 95% CI [52.7–64.1]) guardians of patients sought care within 24 h after fever onset. Children aged 5 to 10 years were less likely to present within 24 h of fever onset than children below 5 years of age (unadjusted odds ratio 0.40, 95% CI [0.2–0.7]).ConclusionAdherence to malaria diagnosis and treatment guidelines was high. However, delayed care seeking and stock outs may affect prompt and effective malaria case management. Further qualitative work is required to determine, and address factors associated with delay in care seeking for fever.

Parasite-based confirmation of malaria with rapid diagnostic tests: Challenges and Advantages

The key to effective case management of malaria is prompt and accurate diagnosis of malaria which is necessary to prevent morbidity and mortality. Accurate and practical malaria diagnostic such as immunochromatographic rapid diagnostic test can avert unnecessary treatments and save lives. Malaria presents a diagnostic challenge in most tropical countries. The urgency and importance of obtaining results quickly from the examination of blood samples from patient with suspected malaria is possible with the introduction of rapid malaria diagnostic test. Rapid diagnostic tests are useful in guiding therapeutic intervention, can be accessible to rural and urban populations, easy to perform and to interpret, affordable, requires no sophicated equipment and prompt treatment of malaria. The use of rapid diagnostic test in the case management of malaria has a lot of challenges which includes: persistent of histidine rich protein 2 in circulation after therapy and parasite death, effect of genetic diversity, lack of quality control on microscopy examination, poor transportation and storage condition, poor regulatory mechanism, lot-to-lot variation, parasite density and lack of extensive training prior to the use of rapid diagnostic test and supervision.

Challenges of achieving sustainable community health services for community case management of malaria

BackgroundCommunity Case Management of malaria (CCMm) using Community Health Workers (CHWs) is an approach to improve access to timely and effective malaria case management in malaria endemic countries. So far the programme has been shown to be effective in many communities in sub-Saharan Africa. However, questions remain on the sustainability of this programme due to the high dropout cases of CHWs given their modest remuneration. The aim of the study was to identify challenges of achieving sustainable community health services for CCMm.MethodsA community based qualitative study was conducted in five districts in western Kenya where CCMm was being undertaken. In-depth interviews and focus group discussions were conducted with the CHWs, mothers of children under-five years and key informants such as public health officers and clinicians involved in the CCMm. The interviews were audio recorded and conducted in English, Swahili and the local language. Recorded interviews were transcribed. Analysis was conducted using NVivo version 7 software, where transcripts were coded after which themes related to the objectives of the study were identified.ResultsThe community members, the CHWs and stakeholders perceived CCMm as an important approach for reducing the burden of malaria. Key informants perceived lack of basic supplies (RDTs, gloves), drugs, inadequate remuneration of CHWs and lack of basic working equipment as challenges for CCM. CHWs highlighted that lack of drugs and basic supplies such as gloves at the health facilities, inadequate community sensitization by health workers, inadequate stipend to meet basic needs, as challenges of achieving sustainable CCMm. Some clinicians perceived that CHWs should not be given Artemisinin-based combination therapy (ACT) as part of the CCMm since they might misuse them.ConclusionThis study shows that for CCMm to be sustainable, concerted efforts from stakeholders are needed to boost the programme. Commodities needed for implementation of the programme need to be readily available and the morale of the CHWs who undertake CCMm needs boosting.

Ex vivo susceptibility and genotyping of Plasmodium falciparum isolates from Pikine, Senegal

BackgroundThe monitoring of Plasmodium falciparum sensitivity to anti-malarial drugs is a necessity for effective case management of malaria. This species is characterized by a strong resistance to anti-malarial drugs. In Senegal, the first cases of chloroquine resistance were reported in the Dakar region in 1988 with nearly 7% population prevalence, reaching 47% by 1990. It is in this context that sulfadoxine–pyrimethamine temporarily replaced chloroquine as first line treatment in 2003, pending the introduction of artemisinin-based combination therapy in 2006. The purpose of this study is to assess the ex vivo sensitivity to different anti-malarial drugs of the P. falciparum population from Pikine.MethodsFifty-four samples were collected from patients with non-complicated malaria and aged between 2 and 20 years in the Deggo health centre in Pikine in 2014. An assay in which parasites are stained with 4′, 6-di-amidino-2-phenylindole (DAPI), was used to study the ex vivo sensitivity of isolates to chloroquine, amodiaquine, piperaquine, pyrimethamine, and dihydroartemisinin. High resolution melting was used for genotyping of pfdhps, pfdhfr, pfmdr1, and pfcrt genes.ResultsThe mean IC50s of chloroquine, amodiaquine, piperaquine, dihydroartemisinin, and pyrimethamine were, respectively, 39.44, 54.02, 15.28, 2.23, and 64.70 nM. Resistance mutations in pfdhfr gene, in codon 437 of pfdhps gene, and an absence of mutation at position 540 of pfdhps were observed. Mutations in codons K76T of pfcrt and N86Y of pfmdr1 were observed at 51 and 11% population prevalence, respectively. A relationship was found between the K76T and N86Y mutations and ex vivo resistance to chloroquine.ConclusionAn increase in sensitivity of isolates to chloroquine was observed. A high sensitivity to dihydroartemisinin was observed; whereas, a decrease in sensitivity to pyrimethamine was observed in the parasite population from Pikine.

The malaria testing and treatment market in Kinshasa, Democratic Republic of the Congo, 2013

BackgroundThe Democratic Republic of Congo (DRC) is one of the two most leading contributors to the global burden of disease due to malaria. This paper describes the malaria testing and treatment market in the nation’s capital province of Kinshasa, including availability of malaria testing and treatment and relative anti-malarial market share for the public and private sector.MethodsA malaria medicine outlet survey was conducted in Kinshasa province in 2013. Stratified multi-staged sampling was used to select areas for the survey. Within sampled areas, all outlets with the potential to sell or distribute anti-malarials in the public and private sector were screened for eligibility. Among outlets with anti-malarials or malaria rapid diagnostic tests (RDT) in stock, a full audit of all available products was conducted. Information collected included product information (e.g. active ingredients, brand name), amount reportedly distributed to patients in the past week, and retail price.ResultsIn total, 3364 outlets were screened for inclusion across Kinshasa and 1118 outlets were eligible for the study. Among all screened outlets in the private sector only about one in ten (12.1%) were stocking quality-assured Artemisinin-based Combination Therapy (ACT) medicines. Among all screened public sector facilities, 24.5% had both confirmatory testing and quality-assured ACT available, and 20.2% had sulfadoxine-pyrimethamine (SP) available for intermittent preventive therapy during pregnancy (IPTp). The private sector distributed the majority of anti-malarials in Kinshasa (96.7%), typically through drug stores (89.1% of the total anti-malarial market). Non-artemisinin therapies were the most commonly distributed anti-malarial (50.1% of the total market), followed by non quality-assured ACT medicines (38.5%). The median price of an adult quality-assured ACT was $6.59, and more expensive than non quality-assured ACT ($3.71) and SP ($0.44). Confirmatory testing was largely not available in the private sector (1.1%).ConclusionsWhile the vast majority of anti-malarial medicines distributed to patients in Kinshasa province are sold within the private sector, availability of malaria testing and appropriate treatment for malaria is alarmingly low. There is a critical need to improve access to confirmatory testing and quality-assured ACT in the private sector. Widespread availability and distribution of non quality-assured ACT and non-artemisinin therapies must be addressed to ensure effective malaria case management.

Quality of Artemisinin-based Combination Therapy for malaria found in Ghanaian markets and public health implications of their use.

BackgroundGhana changed their antimalarial drug policy from monotherapies to Artemisinin-based Combination Therapies in 2004 in order to provide more efficacious medicines for treatment of malaria. The policy change can be eroded if poor quality Artemisinin-based Combination Therapies are allowed to remain on the Ghanaian market unchecked by regulatory bodies and law enforcement agencies. The presence and prevalence of substandard and counterfeit Artemisinin-based Combination Therapies need to be determined on open markets in Ghana; a review of the current policy; identifying any gaps and making recommendations on actions to be taken in addressing gaps identified are essential as the data provided and recommendations made will help in ensuring effective control of malaria in Ghana.MethodsA field survey of antimalarial drugs was conducted in the central part of Ghana. The amount of active pharmaceutical ingredient in each Artemisinin-based Combination Therapy sample identified in the survey was measured using high performance liquid chromatographic analyses. Active pharmaceutical ingredient within the range of 85–115 % was considered as standard and active pharmaceutical ingredient results out of the range were considered as substandard. All samples were screened to confirm stated active pharmaceutical ingredient presence using mass spectrometry.ResultsA total of 256 Artemisinin-based Combination Therapies were purchased from known medicine outlets, including market stalls, hospitals/clinics, pharmacies, drug stores. Artemether lumefantrine (52.5 %) and artesunate amodiaquine (43.2 %) were the predominant Artemisinin-based Combination Therapies purchased. Of the 256 Artemisinin-based Combination Therapies purchased, 254 were tested, excluding two samples of Artesunate-SP. About 35 % of Artemisinin-based Combination Therapies were found to be substandard. Nine percent of Artemisinin-based Combination Therapies purchased were past their expiry date; no counterfeit (falsified) medicine samples were detected by either high performance liquid chromatographic or mass spectrometry.ConclusionA high proportion of Artemisinin-based Combination Therapies sold in central Ghana were found to be substandard. Manufacturing of medicines that do not adhere to good manufacturing practices may have contributed to the poor quality of the Artemisinin-based Combination Therapies procured. A strict law enforcement and quality monitoring systems is recommended to ensure effective malaria case management as part of malaria control.

Placental Malaria is Rare Among Zanzibari Pregnant Women who did not Receive Intermittent Preventive Treatment in Pregnancy

Zanzibar has transitioned from malaria control to the pre-elimination phase, and the continued need for intermittent preventive treatment during pregnancy (IPTp) has been questioned. We conducted a prospective observational study to estimate placental malaria positivity rate among women who did not receive IPTp with sulfadoxine-pyrimethamine. A convenience sample of pregnant women was enrolled from six clinics on the day of delivery from August of 2011 to September of 2012. Dried placental blood spot specimens were analyzed by polymerase chain reaction (PCR); 9 of 1,349 specimens (0.7%; precision estimate = 0.2–1.1%) were PCR-positive for Plasmodium falciparum. Placental infection was detected on both Pemba (N = 3) and Unguja (N = 6). Placental malaria positivity in Zanzibar was low, even in the absence of IPTp. It may be reasonable for the Ministry of Health to consider discontinuing IPTp, intensifying surveillance efforts, and promoting insecticide-treated nets and effective case management of malaria in pregnancy.

Contextualizing Child Malaria Diagnosis and Treatment Practices at an Outpatient Clinic in Southwest Nigeria: A Qualitative Study

Background. This study sought to explore contextual features of an outpatient clinic located in southwest Nigeria that enable and/or discourage effective diagnosis and treatment of child malaria. Methods. We conducted in-depth interviews with mothers of 135 febrile children attending a pediatric outpatient clinic in southwest Nigeria. Also, participant observations and informal discussions with physicians were conducted to examine the potential impact of context on effective child malaria diagnosis and treatment. Results. The findings indicate that availability of drugs and laboratory testing for malaria, affordability of antimalarial drugs, access to the clinic (particularly access to pediatricians), adequacy of the outpatient clinic, and acceptability of services provided at the clinic are key contextual factors that influence effective case management of malaria in children. Conclusion. If the Millennium Development Goal 6 of reversing malaria incidence by 2015 particularly among children is to be achieved, it is necessary to identify the contextual factors that may act as potential barriers to effective diagnosis and treatment practices at clinical settings. Understanding the context in which case management of child malaria occurs can provide insights into the factors that influence mis- and over-diagnosis of malaria in clinical settings.

Factoring Quality Laboratory Diagnosis into the Malaria Control Agenda for Sub-Saharan Africa

Recent progress in malaria control in sub-Saharan Africa has been achieved primarily through provision of insecticide-treated nets, indoor residual spraying, and antimalarial drugs. Although these interventions are important, proper case identification and accurate measurement of their impact depend on quality diagnostic testing. Current availability of diagnostic testing for malaria in sub-Saharan Africa is inadequate to support disease management, prevention programs, and surveillance needs. Challenges faced include a dearth of skilled workforce, inadequate health systems infrastructure, and lack of political will. A coordinated approach to providing pre-service clinical and laboratory training together with systems that support a scale-up of laboratory services could provide means not only for effective malaria case management but also, management of non-malaria febrile illnesses, disease surveillance, and accurate control program evaluation. A synthesis of the challenges faced in ensuring quality malaria testing and how to include this information in the malaria control and elimination agenda are presented.

Creative solutions to extraordinary challenges in clinical trials: methodology of a phase III trial of azithromycin and chloroquine fixed-dose combination in pregnant women in Africa

BackgroundMalaria in pregnancy is one of the most common preventable causes of maternal and neonatal morbidity and mortality in sub-Saharan Africa. To prevent its adverse effects, such as maternal anaemia, placental parasitaemia and low birth weight (LBW) neonates, the World Health Organization recommends effective malaria case management, use of insecticide-treated bed nets and intermittent preventive therapy in pregnancy (IPTp). Sulphadoxine-pyrimethamine (SP) has been the standard for IPTp in several countries, but parasite resistance to SP is growing. Therefore, new IPTp therapies are urgently needed. One candidate being evaluated for IPTp is a fixed-dose combination of azithromycin and chloroquine (AZCQ). This paper describes the challenges and the innovative solutions implemented in designing and conducting a pivotal AZCQ-IPTp trial, sponsored by Pfizer Inc and co-funded by Pfizer Inc and the Medicines for Malaria Venture.MethodsThe AZCQ-IPTp pivotal trial is a multicentre, multicountry, phase III, open-label, randomized superiority study of AZCQ-IPTp versus SP-IPTp in pregnant women of sub-Saharan Africa. The trial was designed to meet stringent regulatory agency scientific advice and IPTp policy makers’ recommendations, and incorporates an innovative adaptive design to manage programme risk, maintain the operating characteristics of the study and optimize resources. The trial’s novel composite primary endpoint is the proportion of participants with a suboptimal pregnancy outcome (abortion [≤28 weeks], stillbirths [>28 weeks], premature [<37 weeks] deliveries, LBW [<2,500 g] live neonates, missing neonatal birth weight data or loss to follow-up). The study employs a prospective group sequential design with three unblinded analyses when 50%, 70% and 100% of participants achieve the primary endpoint; the study team will remain blinded to the analyses until after the completion of the study. The number of participants randomized will be adaptive, based on the blinded review of the observed pooled primary endpoint data across the two treatment arms, when approximately 1,000 participants complete the primary endpoint assessments.ResultsThis study is ongoing and expected to complete in 2014.ConclusionThis report describes the unique challenges and innovative solutions implemented in designing and conducting this pivotal AZCQ-IPTp trial, which may serve as a prototype for future IPTp and other studies involving similar conditions.

Uncomplicated malaria among pregnant women in the Brazilian Amazon: Local barriers to prompt and effective case management

Malaria in pregnancy is associated with increased risks of maternal anemia, spontaneous abortion, low birth weight, premature delivery and other adverse effects on health. In Brazil, disease transmission is highly concentrated in the multi-state region that constitutes the Brazilian Amazon (more than 99% of all cases). This study, conducted between the first bimesters of 2007 and 2008, aims to identify the local barriers to prompt and effective case management of malaria in pregnancy and was carried out in health facilities located in three endemic municipalities of the Brazilian Amazon (Manaus, Presidente Figueiredo and Porto Velho). The study design combined both qualitative and quantitative descriptive methods. The qualitative design involved semi-structured interviews with health personnel who routinely deal with malaria care. The quantitative design involved a review of medical records of pregnant women in the visited health facilities. Additionally, data were abstracted from SIVEP-Malaria Epidemiological Surveillance Information System (Brasil, 2007) and Primary Care Information System (SIAB) databases. Flaws were detected in diagnosis (only 6.8% of women tested for malaria) and treatment (for Plasmodium falciparum infections, only 44.8% of patients received recommended first-line therapy; 10.2% of prescription presented treatments were not found in national guideline and 7.3% of the prescriptions for Plasmodium vivax and 17.9% of the prescriptions for P. falciparum were not sanctioned by the official guidelines). Training (only 37.3% had had some training), knowledge and counseling were also sub-optimal. These results indicated the need to improve the health-worker performance through training. Close supervision and feedback on the health-worker performance are also needed. These findings also highlighted the need to put into practice a series of government recommendations that encourage close collaboration between the National Malaria Control Program and Primary Health Care actions in order to achieve safer pregnancies.

The magnitude and trend of artemether-lumefantrine stock-outs at public health facilities in Kenya

BackgroundHealth facility stock-outs of artemether-lumefantrine (AL), the common first-line therapy for uncomplicated malaria across Africa, adversely affect effective malaria case-management. They have been previously reported on various scales in time and space, however the magnitude of the problem and trends over time are less clear. Here, 2010-2011 data are reported from public facilities in Kenya where alarming stock-outs were revealed in 2008.MethodsData were collected between January 2010 and June 2011 as part of 18 monthly cross-sectional surveys undertaken at nationally representative samples of public health facilities. The primary monitoring indicator was total stock-out of all four weight-specific AL packs. The secondary indicators were stock-outs of at least one AL pack and individual stock-outs for each AL pack. Monthly proportions and summary means of the proportions over the monitoring period were measured for each indicator. Stock-out trends were assessed using linear regression.ResultsThe number of surveyed facilities across 18 time points ranged between 162 and 176 facilities. The stock-out means of the proportion of health facilities were 11.6% for total AL stock-out, 40.6% for stock-out of at least one AL pack, and between 20.5% and 27.4% for stock-outs of individual AL packs. Monthly decrease of the total AL stock-out was 0.005% (95% CI: -0.5 to +0.5; p = 0.983). Monthly decrease in the stock-out of at least one AL pack was 0.7% (95% CI: -1.5 to +0.3; p = 0.058) while stock-outs of individual AL packs decreased monthly between 0.2% for AL 24-pack and 0.7% for AL six-pack without statistical significance for any of the weight-specific packs.ConclusionsDespite lower levels of AL stock-outs compared to the reports in 2008, the stock-outs at Kenyan facilities during 2010-2011 are still substantial and of particular worry for the most detrimental:- simultaneous absence of any AL pack. Only minor decrease was observed in the stock-outs of individual AL packs. Recently launched interventions to eliminate AL stock-outs in Kenya are fully justified.

Preliminary enquiry into the availability, price and quality of malaria rapid diagnostic tests in the private health sector of six malaria‐endemic countries

This enquiry aimed to provide a snap-shot of availability, price and quality of malaria rapid diagnostic tests (RDTs) in private health facilities at selected sites in six malaria-endemic countries in Africa, South East Asia and South America. In each study site, data collectors surveyed private healthcare facilities which were selected based on accessibility from their home institution. Using a questionnaire, information was recorded about the facility itself and the malaria RDT(s) available. Where possible, a small number of RDTs were procured and quality control tested using a standardized procedure. Of the 324 private healthcare facilities visited, 35 outlets (mainly private clinics and hospitals) were found to supply 10 different types of RDTs products. RDT prices across the six countries ranged from US$1.00 to $16.81. Five of the 14 malaria RDTs collected failed quality control testing. In the private outlets sampled, the availability of RDTs was limited. Some of the RDTs whose quality we tested demonstrated inadequate sensitivity. This presents a number of risks. Given the more widespread distribution of antimalarials currently planned for private sector facilities, parasite-based diagnosis in this sector will be essential to adhere to the WHO guidelines for effective case management of malaria. Considerable regulation and quality control are also necessary to assure the availability of accurate and reliable RDTs, as well as adequate case management and provider adherence to RDT results. Public sector engagement is likely to be essential in this process.

Community case management of malaria using ACT and RDT in two districts in Zambia: achieving high adherence to test results using community health workers

BackgroundAccess to prompt and effective treatment is a cornerstone of the current malaria control strategy. Delays in starting appropriate treatment is a major contributor to malaria mortality. WHO recommends home management of malaria using artemisininbased combination therapy (ACT) and Rapid Diagnostic tests (RDTs) as one of the strategies for improving access to prompt and efective malaria case management.MethodsA prospective evaluation of the effectiveness of using community health workers (CHWs) as delivery points for ACT and RDTs in the home management of malaria in two districts in Zambia.ResultsCHWs were able to manage malaria fevers by correctly interpreting RDT results and appropriately prescribing antimalarials. All severe malaria cases and febrile non-malaria fevers were referred to a health facility for further management. There were variations in malaria prevalence between the two districts and among the villages in each district. 100% and 99.4% of the patients with a negative RDT result were not prescribed an antimalarial in the two districts respectively. No cases progressed to severe malaria and no deaths were recorded during the study period. Community perceptions were positive.ConclusionCHWs are effective delivery points for prompt and effective malaria case management at community level. Adherence to test results is the best ever reported in Zambia. Further areas of implementation research are discussed.

District level external quality assurance (EQA) of malaria microscopy in Pakistan: pilot implementation and feasibility.

BackgroundPrompt, quality assured laboratory diagnosis is key to effective malaria case management and control, especially since the introduction of the more expensive artemisinin combination therapy (ACT). The malaria programme and its non-government partners, on the basis of WHO recommended Lot Quality Assurance methods, have developed a district level external quality assurance (EQA) system. This study was designed to assess the feasibility, under programme conditions, of an integrated district level external quality assurance and supervision approach for malaria microscopy.Design and MethodsA prospective study conducted over seven months period (May-November 2007). In addition to the standard WHO EQA elements, three operational innovations were introduced, with the a district laboratory supervisor: a) onsite re-checking of slides, b) in ensuring uninterrupted availability of laboratory reagents and supplies at diagnostic centers, and c) supervision of administrative and technical components. The quantitative data for the study came from the service records/documents, whereas the qualitative data came from the key informant interviews.ResultsDuring the seven month period in four districts, a total of 8,118 slides were examined of which 209 (2.6%) were found positive for malaria parasites (slide positivity range between1.6% to 6.0%). The District Laboratory Supervisors in four districts reexamined a total of 1,770 slides (22%). The proportion of slides found discordant ranged from 0.5% to 1%. The quality of smear preparation was found acceptable in 73% slides.ConclusionsA district-based EQA, based on lot quality assurance methods was implemented, using context-specific operational guidelines, tools and training modules, and other inputs from the malaria control programme and partners. This EQA and supervision approach was found to be feasible and acceptable to those involved. Further study is required on the microscopy quality and cost-effectiveness of adding external quality assurance and supervision to district malaria microscopy services.

The development of a treatment guideline for childhood malaria in rural Southwest Nigeria using participatory approach

Objective To describe the development of a treatment guideline for the effective case management of malaria in children at the home level. Methods Thirty-three mothers selected from 11 communities in a rural health district, community members and the research team developed a guideline for treatment of malaria at home by caregivers using a participatory approach. This was done in phases using modified focus group discussion sessions. Suggested ideas were depicted in illustrations by a graphic artist. Results A guideline which illustrated the presentation of clinical types of malaria, the appropriate steps to take for each type and the correct dosage schedule of chloroquine (based on the age of the child) for treatment of uncomplicated malaria was developed. The guideline was in cartoon format and the script in the local language. Conclusion Use of a participatory approach was found acceptable and effective in the development of the guideline. This approach is therefore recommended irrespective of the target population or the intervention to be developed. Practice implications Preparation of educational materials with contributions from end users does not only build capacity at the local level but also increases the acceptability and ownership of such materials.
