ABSTRACT

Quality improvement of malaria services aims to ensure that more patients receive accurate diagnosis, appropriate treatment, and referral. The Outreach Training and Supportive Supervision Plus (OTSS+) approach seeks to improve health facility readiness and provider competency through onsite supportive supervision, troubleshooting, and on-the-job training. As part of a multicomponent evaluation, qualitative research was conducted to understand the value of the OTSS+ approach for malaria quality improvement. Semistructured key informant interviews, focus group discussions, and structured health facility-based interviews were used to gather stakeholder perspectives at subnational, national, and global levels. Data were collected globally and in 11 countries implementing OTSS+; in-depth data collection was done in four: Cameroon, Ghana, Niger, and Zambia. Study sites and participants were selected purposively. Verbatim transcripts were analyzed thematically, following the Framework approach. A total of 262 participants were included in the analysis; 98 (37.4%) were supervisees, 99 (37.8%) were supervisors, and 65 (24.8%) were other stakeholders. The OTSS+ approach was perceived to improve provider knowledge and skills in malaria service delivery and to improve data and supply management indirectly. Improvements were attributed to a combination of factors. Participants valued the relevance, adaptation, and digitization of supervision checklists; the quality and amount of contact with problem-solving supervisors; and the joint identification of problems and solutions, and development of action plans. Opportunities for improvement were digitized checklist refinement, assurance of a sufficient pool of supervisors, prioritization of health facilities, action plan dissemination and follow-up, and data review and use. The OTSS+ approach was perceived to be a useful quality improvement approach for malaria services.

ABSTRACT

Outreach Training and Supportive Supervision (OTSS) of malaria services at health facilities has been adopted by numerous malaria-endemic countries. The OTSS model is characterized by a hands-on method to enhance national guidelines and supervision tools, train supervisors, and perform supervision visits. An independent evaluation was conducted to evaluate the effectiveness of OTSS on health worker competence in the clinical management of malaria, parasitological diagnosis, and prevention of malaria in pregnancy. From 2018 to 2021, health facilities in Cameroon, Ghana, Niger, and Zambia received OTSS visits during which health workers were observed directly during patient consultations, and supervisors completed standardized checklists to assess their performance. Mixed-effects logistic regression models were developed to assess the impact of increasing OTSS visit number on a set of eight program-generated outcome indicators, including overall competency and requesting a confirmatory malaria test appropriately. Seven of eight outcome indicators showed evidence of beneficial effects of increased OTSS visits. Odds of health workers reaching competency thresholds for the malaria-in-pregnancy checklist increased by more than four times for each additional OTSS visit (odds ratio [OR], 4.62; 95% CI, 3.62-5.88). Each additional OTSS visit was associated with almost four times the odds of the health worker foregoing antimalarial prescriptions for patients who tested negative for malaria (OR, 3.80; 95% CI, 2.35-6.16). This evaluation provides evidence that successive OTSS visits result in meaningful improvements in indicators linked to quality case management of patients attending facilities for malaria diagnosis and treatment, as well as quality malaria prevention services received by women attending antenatal services.

ABSTRACT

BACKGROUND: Use of antigen-detecting malaria rapid diagnostic tests (RDTs) has increased exponentially over the last decade. WHO's Global Malaria Programme, FIND, and other collaborators have established a quality assurance scheme to guide product selection, lot verification, transport, storage, and training procedures. Recent concerns over the quality of buffer packaging and test accessories suggest a need to include these items in product assessments. This paper describes quality problems with buffer and accessories encountered in a project promoting private sector RDT use in five African countries and suggests steps to avoid or more rapidly identify and resolve such problems. METHODS: Private provider complaints about RDT buffer vials and kit accessories were collected during supervisory visits, and a standard assessment process was developed. Using 100 tests drawn from six different lots produced by two manufacturers, lab technicians visually assessed alcohol swab packaging, blood transfer device (BTD) usability, and buffer appearance, then calculated mean blood volume from 10 BTD transfers and mean buffer volume from 10 individual buffer vials. WHO guided complaint reporting and follow-up with manufacturers. RESULTS: Supervisory visits confirmed user reports of dry alcohol swabs, poorly functioning BTDs, and non-uniform volumes of buffer. Lot testing revealed further evidence of quality problems, leading one manufacturer to replace buffer vials and accessories for 40,000 RDTs. In December 2014, WHO issued an Information Notice for Users regarding variable buffer volumes in single-use vials and recommended against procurement of these products until defects were addressed. DISCUSSION: Though not necessarily comprehensive or generalizable, the findings presented here highlight the need for extending quality assessment to all malaria RDT test kit contents. Defects such as those described in this paper could reduce test accuracy and increase probability of invalid, false positive, or false negative results. Such deficiencies could undermine provider confidence in RDTs, prompting a return to presumptive treatment or reliance on poor quality microscopy. In partial response to this experience, WHO, FIND, and other project partners have developed guidance on documenting, troubleshooting, reporting, and resolving such problems when they occur.

ABSTRACT

BACKGROUND: Many patients with malaria-like symptoms seek treatment in private medicine retail outlets (PMR) that distribute malaria medicines but do not traditionally provide diagnostic services, potentially leading to overtreatment with antimalarial drugs. To achieve universal access to prompt parasite-based diagnosis, many malaria-endemic countries are considering scaling up malaria rapid diagnostic tests (RDTs) in these outlets, an intervention that may require legislative changes and major investments in supporting programs and infrastructures. This review identifies studies that introduced malaria RDTs in PMRs and examines study outcomes and success factors to inform scale up decisions. METHODS: Published and unpublished studies that introduced malaria RDTs in PMRs were systematically identified and reviewed. Literature published before November 2016 was searched in six electronic databases, and unpublished studies were identified through personal contacts and stakeholder meetings. Outcomes were extracted from publications or provided by principal investigators. RESULTS: Six published and six unpublished studies were found. Most studies took place in sub-Saharan Africa and were small-scale pilots of RDT introduction in drug shops or pharmacies. None of the studies assessed large-scale implementation in PMRs. RDT uptake varied widely from 8%-100%. Provision of artemisinin-based combination therapy (ACT) for patients testing positive ranged from 30%-99%, and was more than 85% in five studies. Of those testing negative, provision of antimalarials varied from 2%-83% and was less than 20% in eight studies. Longer provider training, lower RDT retail prices and frequent supervision appeared to have a positive effect on RDT uptake and provider adherence to test results. Performance of RDTs by PMR vendors was generally good, but disposal of medical waste and referral of patients to public facilities were common challenges. CONCLUSIONS: Expanding services of PMRs to include malaria diagnostic services may hold great promise to improve malaria case management and curb overtreatment with antimalarials. However, doing so will require careful planning, investment and additional research to develop and sustain effective training, supervision, waste-management, referral and surveillance programs beyond the public sector.

ABSTRACT

Rapid diagnostic tests (RDTs) are widely used for malaria diagnosis, but lack of quality control at point of care restricts trust in test results. Prototype positive control wells (PCW) containing recombinant malaria antigens have been developed to identify poor-quality RDT lots. This study assessed community and facility health workers' (HW) ability to use PCWs to detect degraded RDTs, the impact of PCW availability on RDT use and prescribing, and preferred strategies for implementation in Lao People's Democratic Republic (Laos) and Uganda. A total of 557 HWs participated in Laos (267) and Uganda (290). After training, most (88% to ≥ 99%) participants correctly performed the six key individual PCW steps; performance was generally maintained during the 6-month study period. Nearly all (97%) reported a correct action based on PCW use at routine work sites. In Uganda, where data for 127,775 individual patients were available, PCW introduction in health facilities was followed by a decrease in antimalarial prescribing for RDT-negative patients ≥ 5 years of age (4.7-1.9%); among community-based HWs, the decrease was 12.2% (P < 0.05) for all patients. Qualitative data revealed PCWs as a way to confirm RDT quality and restore confidence in RDT results. HWs in malaria-endemic areas are able to use prototype PCWs for quality control of malaria RDTs. PCW availability can improve HWs' confidence in RDT results, and benefit malaria diagnostic programs. Lessons learned from this study may be valuable for introduction of other point-of-care diagnostic and quality-control tools. Future work should evaluate longer term impacts of PCWs on patient management.

ABSTRACT

BACKGROUND: Successful scale-up in the use of malaria rapid diagnostic tests (RDTs) requires that patients accept testing and treatment based on RDT results and that healthcare providers treat according to test results. Patient-provider communication is a key component of quality care, and leads to improved patient satisfaction, higher adherence to treatment and better health outcomes. Voiced or perceived patient expectations are also known to influence treatment decision-making among healthcare providers. While there has been a growth in literature on provider practices around rapid testing for malaria, there has been little analysis of inter-personal communication around the testing process. We investigated how healthcare providers and patients interact and engage throughout the diagnostic and treatment process, and how the testing service is experienced by patients in practice. METHODS: This research was conducted alongside a larger study which explored determinants of provider treatment decision-making following negative RDT results in a rural district (Kibaale) in mid-western Uganda, ten months after RDT introduction. Fifty-five patients presenting with fever were observed during routine outpatient visits at 12 low-level public health facilities. Observation captured communication practices relating to test purpose, results, diagnosis and treatment. All observed patients or caregivers were immediately followed up with in-depth interview. Analysis followed the 'framework' approach. A summative approach was also used to analyse observation data. RESULTS: Providers failed to consistently communicate the reasons for carrying out the test, and particularly to RDT-negative patients, a diagnostic outcome or the meaning of test results, also leading to confusion over what the test can detect. Patients appeared to value testing, but were frustrated by the lack of communication on outcomes. RDT-negative patients were dissatisfied by the absence of information on an alternative diagnosis and expressed uncertainty around adequacy of proposed treatment. CONCLUSIONS: Poor provider communication practices around the testing process, as well as limited inter-personal exchange between providers and patients, impacted on patients' perceptions of their proposed treatment. Patients have a right to health information and may be more likely to accept and adhere to treatment when they understand their diagnosis and treatment rationale in relation to their perceived health needs and visit expectations.

ABSTRACT

BACKGROUND: The large-scale introduction of malaria rapid diagnostic tests (RDTs) promises to improve management of fever patients and the rational use of valuable anti-malarials. However, evidence on the impact of RDT introduction on the overprescription of anti-malarials has been mixed. This study explored determinants of provider decision-making to prescribe anti-malarials following a negative RDT result. METHODS: A qualitative study was conducted in a rural district in mid-western Uganda in 2011, ten months after RDT introduction. Prescriptions for all patients with negative RDT results were first audited from outpatient registers for a two month period at all facilities using RDTs (n = 30). Facilities were then ranked according to overall prescribing performance, defined as the proportion of patients with a negative RDT result prescribed any anti-malarial. Positive and negative deviant facilities were sampled for qualitative investigation; positive deviants (n = 5) were defined ex post facto as <0.75% and negative deviants (n = 7) as >5%. All prescribing clinicians were targeted for qualitative observation and in-depth interview; 55 fever cases were observed and 22 providers interviewed. Thematic analysis followed the 'framework' approach. RESULTS: 8344 RDT-negative patients were recorded at the 30 facilities (prescription audit); 339 (4.06%) were prescribed an anti-malarial. Of the 55 observed patients, 38 tested negative; one of these was prescribed an anti-malarial. Treatment decision-making was influenced by providers' clinical beliefs, capacity constraints, and perception of patient demands. Although providers generally trusted the accuracy of RDTs, anti-malarial prescription was driven by perceptions of treatment failure or undetectable malaria in patients who had already taken artemisinin-based combination therapy prior to facility arrival. Patient assessment and other diagnostic practices were minimal and providers demonstrated limited ability to identify alternative causes of fever. Provider perceptions of patient expectations sometimes appeared to influence treatment decisions. CONCLUSIONS: The study found high provider adherence to RDT results, but that providers believed in certain clinical exceptions and felt they lacked alternative options. Guidance on how the RDT works and testing following partial treatment, better methods for assisting providers in diagnostic decision-making, and a context-appropriate provider behaviour change intervention package are needed.

ABSTRACT

We conducted a health facility-based survey to estimate the prevalence of malaria among febrile patients at health facilities (HFs) in Maputo City. Patients answered a questionnaire on malaria risk factors and underwent malaria testing. A malaria case was defined as a positive result for malaria by microscopy in a patient with fever or history of fever in the previous 24 hours. Among 706 patients with complete information, 111 (15.7%) cases were identified: 105 were positive for Plasmodium falciparum only, two for Plasmodium ovale only, and four for both P. falciparum and P. ovale. Fever documented at study enrollment, age ≥ 5 years, rural HF, and travel outside Maputo City were statistically significantly associated with malaria by multivariate analysis. We found a high prevalence of laboratory-confirmed malaria among febrile patients in Maputo City. Further studies are needed to relate these findings with mosquito density to better support malaria prevention and control.

ABSTRACT

BACKGROUND: Although the molecular basis of resistance to a number of common antimalarial drugs is well known, a geographic description of the emergence and dispersal of resistance mutations across Africa has not been attempted. To that end we have characterised the evolutionary origins of antifolate resistance mutations in the dihydropteroate synthase (dhps) gene and mapped their contemporary distribution. METHODS AND FINDINGS: We used microsatellite polymorphism flanking the dhps gene to determine which resistance alleles shared common ancestry and found five major lineages each of which had a unique geographical distribution. The extent to which allelic lineages were shared among 20 African Plasmodium falciparum populations revealed five major geographical groupings. Resistance lineages were common to all sites within these regions. The most marked differentiation was between east and west African P. falciparum, in which resistance alleles were not only of different ancestry but also carried different resistance mutations. CONCLUSIONS: Resistant dhps has emerged independently in multiple sites in Africa during the past 10-20 years. Our data show the molecular basis of resistance differs between east and west Africa, which is likely to translate into differing antifolate sensitivity. We have also demonstrated that the dispersal patterns of resistance lineages give unique insights into recent parasite migration patterns.

ABSTRACT

A malária continua a ser o principal desafio para a saúde pública e para o desenvolvimento sustentável em Moçambique. Apesar dos esforços empreendidos pelo MISAU e Parceiros na luta contra Malária, esta doença para além do impacto directo na saúde da população, ainda exerce um peso socioeconómico enorme na população em geral, perpetuando desta forma o ciclo vicioso de doença/pobreza sobretudo nas comunidades mais desfavorecidas e vulneráveis. Dados do Programa Nacional de Controlo da Malária indicam uma tendência crescente de número de casos de malária notificados nos últimos 3 anos, associado ao aumento da taxa de reporte e melhoria da notificação. Por outro lado, observa-se com satisfação a diminuição do número de óbitos causados pela doença. A redução dos óbitos devido a malária pode ser atribuída ao conjunto de esforços empreendidos do Programa Nacional de Controlo da Malária, na implementação de medicamentos e intervenções eficazes na componente de manejo de casos doença. No manejo das síndromes febris, é necessário ter em conta que muitos casos de febre não são

ABSTRACT

The prevalence and frequency of the dihydrofolate reductase (dhfr) and dihydropteroate synthetase (dhps) mutations associated with sulfadoxine-pyrimethamine (SP) resistance at 13 sentinel surveillance sites in southern Mozambique were examined regularly between 1999 and 2004. Frequency of the dhfr triple mutation increased from 0.26 in 1999 to 0.96 in 2003, remaining high in 2004. The dhps double mutation frequency peaked in 2001 (0.22) but declined to baseline levels (0.07) by 2004. Similarly, parasites with both dhfr triple and dhps double mutations had increased in 2001 (0.18) but decreased by 2004 (0.05). The peaking of SP resistance markers in 2001 coincided with a SP-resistant malaria epidemic in neighboring KwaZulu-Natal, South Africa. The decline in dhps (but not dhfr) mutations corresponded with replacement of SP with artemether-lumefantrine as malaria treatment policy in KwaZulu-Natal. Our results show that drug pressure can exert its influence at a regional level rather than merely at a national level.

ABSTRACT

BACKGROUND: It is estimated that over 70% of patients with suspected malaria in sub-Saharan Africa, diagnose and manage their illness at home without referral to a formal health clinic. Of those patients who do attend a formal health clinic, malaria overdiagnosis rates are estimated to range between 30-70%. METHODS: This paper details an observational cohort study documenting the number and cost of repeat consultations as a result of malaria overdiagnosis at two health care providers in a rural district of Mozambique. 535 adults and children with a clinical diagnosis of malaria were enrolled and followed over a 21 day period to assess treatment regimen, symptoms, number and cost of repeat visits to health providers in patients misdiagnosed with malaria compared to those with confirmed malaria (determined by positive bloodfilm reading). RESULTS: Diagnosis based solely on clinical symptoms overdiagnosed 23% of children (<16y) and 31% of adults with malaria. Symptoms persisted (p = 0.023) and new ones developed (p < 0.001) in more adults than children in the three weeks following initial presentation. Adults overdiagnosed with malaria had more repeat visits (67% v 46%, p = 0.01-0.06) compared to those with true malaria. There was no difference in costs between patients correctly or incorrectly diagnosed with malaria. Median costs over three weeks were $0.28 for those who had one visit and $0.76 for > or = 3 visits and were proportionally highest among the poorest (p < 0.001) CONCLUSION: Overdiagnosis of malaria results in a greater number of healthcare visits and associated cost for adult patients. Additionally, it is clear that the poorest individuals pay significantly more proportionally for their healthcare making it imperative that the treatment they receive is correct in order to prevent wastage of limited economic resources. Thus, investment in accurate malaria diagnosis and appropriate management at primary level is critical for improving health outcomes and reducing poverty.

ABSTRACT

A malária ainda continua sendo um dos principais problemas de saúde pública em Moçambique. O Ministério de Saúde através do Programa Nacional de Controlo da Malária delineou estratégias para a expansão massiva de intervenções com o objectivo de acelerar a redução do peso da malária. A avaliação sistemática destas intervenções, através de indicadores-chave é de extrema importância para a monitorização dos resultados e consequentemente guiar na tomada de decisões para futuras estratégias de implementação, bem como no ajuste das intervenções de prevenção e controlo da malária. Este relatório apresenta os resultados do primeiro Inquérito sobre os Indicadores da Malária (IIM) em Moçambique, realizado pelo Programa Nacional de Controlo da Malária em parceria com instituições nacionais e estrangeiras, entre Junho e Julho de 2007, como parte da avaliação e estabelecimento de uma linha de base de alguns indicadores malariométricos chave (propostos pela parceria Fazer Recuar a Malária ­ FRM) ao nível das comunidades e ao nível dos agregados familiares. O IIM de Moçambique foi desenhado de acordo com as recomendações gerais de IIM publicado pelo Grupo de Referência de Monitoria e Avaliação (MERG) da FRM com algumas modifi cações necessárias para se adequar a situação particular do país. A amostra foi desenhada pelo Instituto Nacional de Estatística usando a amostra primária ou "mãe" que é uma amostra grande, estratifi cada com três etapas de selecção usada no recenseamento geral da população (RGPH) de 1997 e é usada para todos os inquéritos nacionais de agregados familiares em Moçambique. Desta forma, 346 aglomerados com 5990 agregados familiares foram seleccionados dos 1510 aglomerados da amostra primária. O princípio de desenho da amostra é o de uma amostra de probabilidade representativa, estratifi cada de modo a produzir estimativas para o país como um todo, as áreas rurais e urbanas em separado e pelos principais domínios (províncias). Um total de 5745 registos completos de agregados familiares foram usados para a análise fi nal, tendo-se observado uma perda de apenas 4.1%. As amostras da análise também incluíram 5637 mulheres com idades entre 15-49 anos, 589 mulheres grávidas e 1268 crianças com um episódio de febre nos últimos 14 dias anteriores à data do inquérito. As principais áreas de estudo deste inquérito contemplavam a cobertura e uso de redes mosquiteiras tratadas com insecticida de longa duração (RMILD); a cobertura com a pulverização intra-domiciliária; o Tratamento Intermitente Presumptivo (TIP) na gravidez; prevalência da infecção malárica e anemia a ela relacionada; a procura de cuidados de saúde e manejo da febre em crianças; e os conhecimentos da mulher em relação à malária. Em resumo, os principais resultados do inquérito foram os seguintes: A cobertura de redes mosquiteiras ainda é muito baixa, estima-se em cerca de 15.8% a proporção de agregados familiares com pelo menos uma rede mosquiteira (RMTI) e cerca de 18.5% a proporção de agregados familiares com uma mulher grávida e/ou crianças menores de cinco anos de idade que possuem pelo menos uma RMTI. Em relação ao uso de redes mosquiteiras, a proporção de crianças menores de cinco anos de idade que dormiu em baixo de uma rede mosquiteira na noite anterior ao inquérito foi de 6.7% enquanto que a proporção de mulheres grávidas que dormiu debaixo duma rede mosquiteira na noite anterior ao inquérito foi de 7.3%. Programa Nacional de Controlo da Malária Inquérito Nacional sobre Indicadores de Malária em Moçambique (IIM 2007) 12 No que diz respeito à cobertura pela pulverização intradomiciliária, a proporção de casas pulverizadas nos últimos 12 meses anteriores ao inquérito nos distritos-alvo foi de 52.4%. Esta cobertura ainda está longe do desejado para se atingir uma protecção efi caz. Em relação ao TIP, durante a gravidez, o inquérito mostrou que a proporção de mulheres que terminou uma gravidez no ano anterior ao inquérito e que recebeu pelo menos duas ou mais doses de TIP durante aquela gravidez foi de 20.3% e a proporção de mulheres que terminou uma gravidez no ano anterior ao inquérito e frequentou a consulta pré-natal pelo menos duas vezes e que recebeu duas ou mais doses de TIP durante aquela gravidez foi de 23.3%. O inquérito mostrou que a prevalência da febre (temperatura axilar >37,5) foi de 9.7%. Aproximadamente 38.5% das crianças eram portadoras de parasita da malária. A proporção de crianças menores de 5 anos com anemia (hb<11g/dL) foi de 67.7% e cerca de 11.9% apresentava uma anemia severa (hb<8d/dL). Em relação às mulheres grávidas, 16.3% era portadoras de parasitas de malária, proporção com anemia foi de 48.1% e cerca de 5.1% tinha anemia severa. Outro aspecto pesquisado foi a procura de cuidados médicos para o tratamento de episódios de febre em crianças menores de cinco anos de idade. O inquérito mostrou que a proporção de crianças com febre nas 2 semanas anteriores para as quais foi procurado tratamento em 24 horas foi de 36.3%, enquanto que a proporção de crianças menores de cinco anos de idade com febre nas duas semanas anteriores, que receberam qualquer tratamento para a malária em 24 horas após o início da febre foi de 17.6% e destas apenas 4.5% receberam tratamento com anti-maláricos combinados com derivados de artemizinina. Em relação ao conhecimento sobre a malária, a proporção de mulheres que sabe que a febre é o principal sintoma da malária foi bastante alta cerca de 70.0%, mas somente 12.4% referiu que a anemia é um sintoma importante da malária. Para o modo de transmissão da doença, 35.3% dos entrevistados relacionou transmissão da malária apenas pelos mosquitos. Nas medidas de prevenção, somente 28.6% das mulheres entrevistadas sabiam que as redes mosquiteiras são um meio de prevenção da malária, contudo cerca de 60% das mulheres sabem que a mulher grávida e crianças menores constituem um grupo de maior risco. Com os resultados deste inquérito pode-se concluir que a malária e a anemia associada à malária ainda constituem um problema de saúde pública, sobretudo nas comunidades rurais de Moçambique. A procura de cuidados de saúde para crianças, especialmente aquelas com um síndrome febril ainda é muito baixo e a maioria dos que procuram se têm suspeita de malária as unidades sanitárias ainda fazem tratamento mono-terapêutico, apesar da política vigente que recomenda a combinação terapêutica com derivados da artemisinina. A maior parte das mulheres que zelam pela saúde da criança, não associam alguns sintomas importantes da malária com a da doença, como por exemplo a anemia. Na comunidade a falta de conhecimentos sobre a malária foi notória, sobretudo no modo de transmissão e nos métodos de prevenção da doença. A posse de rede mosquiteira por agregado familiar é muita baixa e menos de metade desses agregados familiares reportaram o uso da rede na noite anterior ao inquérito. Este IIM fornece assim uma avaliação compreensiva das intervenções chave de cobertura e um marco do progresso alcançado na expansão. Por ser o primeiro estudo do género, irá certamente fornecer linhas de base para vários indicadores do Plano Nacional de Prevenção e Controlo da Malária período 2010 ­ 2014
