Omale UI, Azuogu BN, Agu AP, Ossai EN. Use of malaria rapid diagnostic test and anti-malarial drug prescription practices among primary healthcare workers in Ebonyi state, Nigeria: An analytical cross-sectional study. PLoS One 2024; 19:e0304600. [PMID: 38833491 PMCID: PMC11149890 DOI: 10.1371/journal.pone.0304600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Accepted: 05/14/2024] [Indexed: 06/06/2024] Open
Abstract
BACKGROUND The recommendation of universal diagnostic testing before malaria treatment aimed to address the problem of over-treatment with artemisinin-based combination therapy and the heightened risk of selection pressure and drug resistance and the use of malaria rapid diagnostic test (MRDT) was a key strategy, particularly among primary healthcare (PHC) workers whose access to and use of other forms of diagnostic testing were virtually absent. However, the use of MRDT can only remedy over-treatment when health workers respond appropriately to negative MRDT results by not prescribing anti-malarial drugs. This study assessed the use of MRDT and anti-malarial drug prescription practices, and the predictors, among PHC workers in Ebonyi state, Nigeria. METHODS We conducted an analytical cross-sectional questionnaire survey, among consenting PHC workers involved in the diagnosis and treatment of malaria, from January 15, 2020 to February 5, 2020. Data was collected via structured self-administered questionnaire and analysed using descriptive statistics and bivariate and multivariate generalized estimating equations. RESULTS Of the 490 participants surveyed: 81.4% usually/routinely used MRDT for malaria diagnosis and 18.6% usually used only clinical symptoms; 78.0% used MRDT for malaria diagnosis for all/most of their patients suspected of having malaria in the preceding month while 22.0% used MRDT for none/few/some; 74.9% had good anti-malarial drug prescription practice; and 68.0% reported appropriate response to negative MRDT results (never/rarely prescribed anti-malarial drugs for the patients) while 32.0% reported inappropriate response (sometimes/often/always prescribed anti-malarial drugs). The identified predictor(s): of the use of MRDT was working in health facilities supported by the United States' President's Malaria Initiative (PMI-supported health facilities); of good anti-malarial drug prescription practice were having good opinion about MRDT, having good knowledge about malaria diagnosis and MRDT, being a health attendant, working in PMI-supported health facilities, and increase in age; and of appropriate response to negative MRDT results was having good opinion about MRDT. CONCLUSIONS The evidence indicate the need for, and highlight factors to be considered by, further policy actions and interventions for optimal use of MRDT and anti-malarial drug prescription practices among the PHC workers in Ebonyi state, Nigeria, and similar settings.

Omale UI. A qualitative study on determinants of the use of malaria rapid diagnostic test and anti-malarial drug prescription practices by primary healthcare workers in Ebonyi state, Nigeria. Malar J 2024; 23:120. [PMID: 38664678 PMCID: PMC11046898 DOI: 10.1186/s12936-024-04958-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Accepted: 04/22/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND The increased availability and use of malaria rapid diagnostic test (RDT) by primary healthcare (PHC) workers has made universal diagnostic testing before malaria treatment more feasible. However, to meaningfully resolve the problem of over-treatment with artemisinin-based combination therapy and the heightened risk of selection pressure and drug resistance, there should be appropriate response (non-prescription of anti-malarial drugs) following a negative RDT result by PHC workers. This study explored the determinants of the use of RDT and anti-malarial drug prescription practices by PHC workers in Ebonyi state, Nigeria. METHODS Between March 2 and 10, 2020, three focus group discussions were conducted in English with 23 purposively-selected consenting PHC workers involved in the diagnosis and treatment of malaria. Data was analysed thematically as informed by the method by Braun and Clarke. RESULTS The determinants of the use of RDT for malaria diagnosis were systemic (RDT availability and patient load), provider related (confidence in RDT and the desire to make correct diagnosis, PHC worker's knowledge and training, and fear to prick a patient), client related (fear of needle prick and refusal to receive RDT, and self-diagnosis of malaria, based on symptoms, and insistence on not receiving RDT), and RDT-related (the ease of conducting and interpreting RDT). The determinants of anti-malarial drug prescription practices were systemic (drug availability and cost) and drug related (effectiveness and side-effects of the drugs). The determinants of the prescription of anti-malarial drugs following negative RDT were provider related (the desire to make more money and limited confidence in RDT) and clients' demand while unnecessary co-prescription of antibiotics with anti-malarial drugs following positive RDT was determined by the desire to make more money. CONCLUSIONS This evidence highlights many systemic, provider, client, and RDT/drug related determinants of PHC workers' use of RDT and anti-malarial drug prescription practices that should provide tailored guidance for relevant health policy actions in Ebonyi state, Nigeria, and similar settings.

Request for Antimalarial Medicines and Their Dispensing Without a Prescription in Community Pharmacies in Rwanda. INTEGRATED PHARMACY RESEARCH AND PRACTICE 2023; 12:195-212. [PMID: 37928945 PMCID: PMC10625414 DOI: 10.2147/iprp.s428105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 10/20/2023] [Indexed: 11/07/2023] Open
Abstract
Purpose This study aimed to explore the request and dispensing of antimalarial medicines without a prescription in community pharmacies in Rwanda, as well as factors associated. Methods We employed an embedded mixed-methods design that involved a convenience sample of 235 licensed community pharmacists between February and April 2022. To simultaneously collect qualitative and quantitative data, we used a self-administered questionnaire containing a combination of close and open-ended questions. Bivariate and multivariate regression analyses were performed to examine the relationship between dispensing antimalarial medicines without a prescription and the selected independent variables. Statistical significance was set at p<0.05, and a 95% confidence interval was applied. The factors influencing the dispensing of antimalarial medicines without a prescription were analyzed using thematic content analysis as a qualitative analysis approach. Results Most respondents (88.5%) were asked to dispense antimalarial medicines by clients without a prescription. More than half of them (54%) agreed, but 34.5% refused; instead, they referred clients to malaria diagnostic testing facilities. Those who had rapid diagnostic tests for malaria in stock (OR=2.08, 95% CI:1.1-3.94), and thought that antimalarials were over-the-counter medicines (OR=7.03, 95% CI:2.01-24.5) were more likely to dispense antimalarial medicines without prescriptions. The primary reasons reported by community pharmacists for dispensing antimalarial medicines without prescriptions included their prior knowledge of malaria diagnosis, client pressure, and fear of losing clients. However, non-adherence to negative results obtained from formal health facilities and long queues at these institutions have also been cited as additional factors driving clients to seek antimalarial medicines without prescriptions. Conclusion Dispensing antimalarial medicines without prescriptions is a common practice in community pharmacies in Rwanda. The main factors contributing to this practice include lack of awareness regarding the classification of antimalarials as prescription medicines, the availability of malaria diagnostic tests, client pressure, and fear of losing clients.

Malaria rapid diagnostic tests in community pharmacies in Rwanda: availability, knowledge of community pharmacists, advantages, and disadvantages of licensing their use. Glob Health Res Policy 2023; 8:40. [PMID: 37700374 PMCID: PMC10496312 DOI: 10.1186/s41256-023-00324-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 08/22/2023] [Indexed: 09/14/2023] Open
Abstract
BACKGROUND Presumptive treatment of malaria is often practiced in community pharmacies across sub-Saharan Africa (SSA).To address this issue, the World Health Organization (WHO) recommends that malaria Rapid Diagnostic Tests (m-RDTs) be used in these settings, as they are used in the public sector. However, their use remains unlicensed in the community pharmacies in Rwanda. This can lessen their availability and foster presumptive treatment. Therefore, this study investigated the availability of m-RDTs, knowledge of community pharmacists on the use of m-RDTs, and explored Pharmacists' perceptions of the advantages and disadvantages of licensing the use of m-RDTs in community pharmacies. METHODS This was a cross-sectional study among 200 licensed community pharmacists who were purposefully sampled nationwide from 11th February to 12th April 2022. Data was collected using an online data collection instrument composed of open-ended and closed-ended questions. Statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 25.0. The chi-square test was used to evaluate the association between the availability of m-RDTs and independent variables of interest. Content analysis was used for qualitative data. RESULTS Although 59% were consulted by clients requesting to purchase m-RDTs, only 27% of the participants had m-RDTs in stock, 66.5% had no training on the use of m-RDTs, and 18.5% were not at all familiar with using the m-RDTs. Most of the participants (91.5%) agreed that licensing the use of m-RDTs in community pharmacies could promote the rational use of antimalarials. The chi-square test indicated that being requested to sell m-RDTs (x2 = 6.95, p = 0.008), being requested to perform m-RDTs (x2 = 5.39, p = 0.02),familiarity using m-RDTs (x2 = 17.24, p = 0.002), availability of a nurse in the Pharmacy (x2 = 11.68, p < 0.001), and location of the pharmacy (x2 = 9.13, p = 0.048) were all significantly associated with the availability of m-RDTs in the pharmacy. CONCLUSIONS The availability of m-RDTs remains low in community pharmacies in Rwanda, and less training is provided to community pharmacists regarding the use of m-RDTs. Nevertheless, community pharmacists had positive perceptions of the advantages of licensing the use of m-RDTs. Thus, licensing the use of m-RDTs is believed to be the first step toward promoting the rational use of antimalarial medicines in Rwanda.

Abstract
BACKGROUND Point-of-care testing (POCT) using rapid diagnostic tests for infectious disease can potentially guide appropriate use of antimicrobials, reduce antimicrobial resistance, and economise use of healthcare resources. POCT implementation in private retail settings such as pharmacies and drug shops could lessen the burden on public healthcare. We performed a narrative review on studies of POCTs in low- and middle-income countries (LMICs), and explored uptake, impact on treatment, and feasibility of implementation. METHODS We searched MEDLINE/PubMed for interventional studies on the implementation of POCT for infectious diseases performed by personnel in private retail settings. Data were extracted and analysed by two independent reviewers. RESULTS Of the 848 studies retrieved, 23 were included in the review. Studies were on malaria (19/23), malaria and pneumonia (3/23) or respiratory tract infection (1/23). Nine randomised controlled studies, four controlled, non-randomised studies, five uncontrolled interventions, one interventional pre-post study, one cross-over interventional study and three retrospective analyses of RCTs were included. Study quality was poor. Overall, studies showed that POCT can be implemented successfully, leading to improvements in appropriate treatment as measured by outcomes like adherence to treatment guidelines. Despite some concerns by health workers, customers and shop providers were welcoming of POCT implementation in private retail settings. Main themes that arose from the review included the need for well-structured training with post-training certification covering guidelines for test-negative patients, integrated waste management, community sensitization and demand generation activities, financial remuneration and pricing schemes for providers, and formal linkage to healthcare and support. CONCLUSION Our review found evidence that POCT can be implemented successfully in private retail settings in LMICs, but comprehensive protocols are needed. High-quality randomised studies are needed to understand POCTs for infectious diseases other than malaria.

Abstract
BACKGROUND Inappropriate antibiotic dispensing is one of the key drivers of antibiotic resistance. This review documents the effectiveness of interventions aimed at improving antibiotic dispensing practices at the community level by drug dispensers in low and middle income countries (LMIC). METHODS We conducted a systematic search in PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science (November 11, 2019). Studies were included if they reported data on the outcome measure: appropriate dispensing of medicine including antibiotics. The effectiveness of studies was assessed based on quantitative results reported in the studies included. RESULTS A total of 1158 papers were screened. Thirteen studies from Asia (6), Africa (5), South America (one) and one study from both Africa and Asia were included in this review. Nine (69.2%) studies reported significant effectiveness of interventions on all or more than 50% of antibiotic related outcomes. Cochrane Effective Practice and Organization of Care interventions frequently applied were educational meetings (9/13), distribution of educational materials (7/13), educational outreach meetings (7/13), reminders (6/13), local consensus processes (6/13), distribution of supplies (6/14) and clinical practice guidelines (4/14), Nine studies reported on stakeholder involvement. CONCLUSION This review shows that it is possible to improve antibiotic dispensing practices at the community level in LMIC. Stakeholders' involvement was key in the design and implementation of interventions.

Abstract
Introduction community volunteers have limited skills but are an important link between the community and health facilities. We determined the effect of a capacity building intervention on knowledge of malaria control and attitudes towards community involvement among female community volunteers as part of a larger community-based intervention study on pregnant women and children under five. Methods we conducted a before and after intervention study (no randomization or controls) among female community volunteers in Amagu community in Abakaliki Local Government Area. The intervention consisted of training sessions on knowledge of malaria and its control. The training took the form of lectures, role plays and practical demonstrations. Supportive supervision by trained community health extension workers was also provided during their field work. We compared pre-training test and post-training test scores after six months interval and analysed the data using paired t test at 5% level of significance with EPI INFO software version 7.2.3. Results the mean age of the participants was 28.5(± 6.0) years. All had a minimum level of secondary education. There was significant improvement in the mean scores of their knowledge of malaria signs and symptoms (p < 0.001), preventive measures (p < 0.001) and appropriate drug treatment (p < 0.001) in the post-training test when compared with the pre-training test. The overall mean knowledge scores pre and posttest were 147.8 and 169.8 respectively (p < 0.001) out of a maximum achievable score of 195. Also there was significant improvement in the perception of the participants on community involvement in promoting referral of pregnant women with fever (p = 0.001), the use of intermittent preventive therapy with sulphadoxine-pyrimethamine (p = 0.048) and funding initiatives to sustain activities (p = 0.037). Conclusion capacity building of female community volunteers coupled with supportive supervision by trained community health workers improved the female community volunteers´ knowledge of malaria, its control and their perception of community involvement in control activities. It is recommended that the use of community volunteers as a low cost health resource can be explored further for incorporation into existing policies on malaria control in resource constrained environments.

Abstract
Background Nigeria accounts for approximately 25% of the global malaria burden. Malaria is a major cause of morbidity and mortality, especially in children and pregnant women. Pharmacists play vital roles in the fight against malaria. However, in Nigeria, the role of the community pharmacist in managing cases of malaria has received very little research attention. This study aimed to evaluate the level of participation of community pharmacists in the management of malaria cases in Enugu metropolis and to explore factors associated with such participation. Methods A cross-sectional survey was conducted among community pharmacists in Enugu metropolis using a modified and re-validated 16-item self-administered questionnaire. The questionnaire was distributed to participants in selected pharmacies for completion. Descriptive statistics and the chi-square test were used for statistical analysis. Results Out of the 103 participants, more than half (55.3%) were male. More than half of the pharmacists satisfactorily provided preventive (57.3%), pharmaceutical (62.1%), and curative (51.1%) services for patients with malaria. Overall, 57% of the pharmacists satisfactorily participated in the management of malaria cases. The number of years of practice was significantly associated with the pharmacists level of involvement in preventive (P=0.003) and curative (P=0.018) services. However, the provision of pharmaceutical care services for malaria patients was significantly associated with the sex of the respondents (P=0.023). Conclusions Our results suggest that more than half of the community pharmacists in Enugu metropolis were satisfactorily involved in the management of malaria cases. However, the number of years of practice and sex were factors associated with the extent of pharmacist involvement in the management of malaria cases.

Abstract
OBJECTIVES To summarise the literature regarding the use of point-of-care test (POCT) in pharmacies versus control/usual care. DESIGN AND SETTING Systematic review and random-effects meta-analysis in community pharmacy. DATA SOURCES MEDLINE, Cochrane Central Register of Controlled Trials, Embase, ClinicalTrial.gov and Web of Science databases were searched. ELIGIBILITY CRITERIA Articles were included if they: involved a POCT conducted by a community pharmacist, member of pharmacy staff or local equivalent; measured a clinically relevant outcome for example, clinical parameter monitoring. No clinical condition or language limits were set. PATIENT AND PUBLIC INVOLVEMENT No patient involvement. DATA EXTRACTION AND SYNTHESIS Data were independently extracted by two members of the review team to capture changes in clinical care that resulted from the use of the POCTs. The methodological quality of included studies was assessed, using the Cochrane Risk of Bias tool and Newcastle-Ottawa scale. RESULTS Thirteen of the 1584 articles found were included in the meta-analyses. Studies covered four therapeutic areas: targeted anti-malarial therapy (n=3 studies), glycated haemoglobin (HbA1c) in diabetes (n=2 studies), lipid control (n=3 studies) and international normalised ratio (INR) control in patients taking warfarin (n=5 studies). POCT in pharmacies reduced the risk of receiving antimalarial treatment when not clinically indicated (risk ratio 0.34, 95% CI 0.31 to 0.37). Lipid and HbA1c control appeared largely unaffected by pharmacy POCTs, and the impact on INR time-in-therapeutic-range was inconclusive. CONCLUSIONS Only 4 out of 13 included studies used a gold-standard randomised controlled trial (RCT) design, limiting our ability to conclusively determine the clinical utility of POCT conducted in pharmacies. Further RCTs are needed, particularly in areas such as upper respiratory tract infections, which have gathered momentum among service commissioners in recent years.

Gmanyami JM, Ameko A, Ahiafe SS, Bosoka SA, Kweku M, Ansah EK. Effect of pre-consultation testing on clinicians' adherence to malaria test results and waiting time among children under 5 years in the Northern Zone of Volta Region of Ghana. Malar J 2020; 19:120. [PMID: 32197616 PMCID: PMC7085133 DOI: 10.1186/s12936-020-03189-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 03/11/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The Ministry of Health, Ghana, in accordance with global policy, recommends that all suspected malaria cases be confirmed parasitologically before treatment. Not all clinicians, however, base their treatment on test results. Patients also spend a lot of time at health facilities waiting to consult a clinician before being asked to go for testing and to see a clinician with test results. The purpose of the study was to determine if testing all children aged 6 to 59 months with fever reporting at an outpatients department (OPD) for malaria before consultation with a clinician (pre-consultation testing) will influence clinicians to adhere to test results and also reduce the time spent by such patients. METHODS A quasi-experimental study design was used involving two randomly selected government-owned hospitals in the Northern Volta, Ghana. In each hospital, 439 children were recruited between November 2018 and January 2019. The intervention hospital implemented pre-consultation testing. In the comparator arm, standard practices, which involved patients seeing the clinician before he/she decides whether to send the patient for testing or not, were maintained. RESULTS Out of 878 children screened the overall prevalence of malaria was 31.9% by malaria rapid diagnostic test (RDT) and 26.7% by microscopy. Clinicians in the intervention arm adhered more to the malaria test results than those in the comparator arm (93.2 vs. 84.3%; p < 0.001). The proportion of children who tested negative but were still diagnosed with malaria was significantly lower in the intervention arm compared to the comparator arm (8.4 vs. 21.2%: p < 0.001). Clinicians and mothers/caregivers in both arms preferred pre-consulting testing. Six out of every 10 mothers/caregivers in the comparator arm viewed the waiting time as 'too long'' compared to 4 out of every 10 mothers in the intervention arm. On average, patient waiting time was significantly lower in the intervention arm (2.61 h) than in the comparator arm (3.42 h). CONCLUSION Pre-consultation testing significantly improves clinicians' adherence to malaria test results, shortens patients' waiting time and leads to overall patient satisfaction. There is a need to establish RDT corners at OPDs of health facilities to implement pre-consultation testing.

Social group and health care provider interventions to increase the demand for malaria rapid diagnostic test among community members in Ebonyi state, Nigeria: study protocol for a cluster randomized controlled trial. Trials 2019; 20:581. [PMID: 31601250 PMCID: PMC6785898 DOI: 10.1186/s13063-019-3620-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2019] [Accepted: 07/29/2019] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND The World Health Organization recommended (in 2010) universal testing for suspected malaria, due to some fundamental changes in malaria trends such as the declining incidence of malaria in high-burden countries, the emergence of parasite resistance to anti-malarial drugs especially artemisinin-based combination therapies (ACTs) and the increased availability of diagnostic testing such as the malaria rapid diagnostic test (MRDT). The Nigerian government has long adopted this recommendation and with the support of foreign partners has scaled up the availability of MRDT. However, the malaria/MRDT rate in the communities is still far short of the recommendation. This study aims to evaluate the effectiveness of social group and social group/provider interventions in increasing the demand (use and/or request) for MRDT among community members with fever or malaria-like illness in Ebonyi state, Nigeria. METHODS A three-arm, parallel, stratified cluster randomized design will be used to evaluate the effect of two interventions compared to control: control involves the usual practice of provision of MRDT services by public primary healthcare providers and patent medicine vendors; social group intervention involves the sensitization/education of social groups about MRDT; social group/provider intervention involves social group treatment plus the training of healthcare providers in health communication about MRDT with clients. The primary outcome is the proportion of children under 5 years of age with fever/malaria-like illness, in the 2 weeks preceding a household survey, who received MRDT. The co-primary outcome is the proportion of children ages 5 years and above and adults (excluding pregnant women) with fever/malaria-like illness, in the 2 weeks preceding a household survey, who received MRDT. The primary outcome will be assessed through household surveys at baseline and at the end of the study. DISCUSSION The pragmatic and behavioural nature of the interventions delivered to groups of individuals and the need to minimize contamination informed the use of a cluster-randomized design in this study in investigating whether the social group and social group/provider interventions will increase the demand for MRDT among community members. "Pragmatic" means the interventions would occur in natural settings or real- life situations. TRIAL REGISTRATION ISRCTN, ISRCTN14046444 . Registered on 14 August 2018.

Can malaria rapid diagnostic tests by drug sellers under field conditions classify children 5 years old or less with or without Plasmodium falciparum malaria? Comparison with nested PCR analysis. Malar J 2018; 17:365. [PMID: 30326926 PMCID: PMC6192306 DOI: 10.1186/s12936-018-2508-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 10/06/2018] [Indexed: 01/02/2023] Open
Abstract
Background Malaria rapid diagnostic tests (RDTs) available as dipsticks or strips, are simple to perform, easily interpretable and do not require electricity nor infrastructural investment. Correct interpretation of and compliance with the RDT results is a challenge to drug sellers. Thus, drug seller interpretation of RDT strips was compared with laboratory scientist re-reading, and PCR analysis of Plasmodium DNA extracted from RDT nitrocellulose strips and fast transient analysis (FTA) cards. Malaria RDT cassettes were also assessed as a potential source of Plasmodium DNA. Methods A total of 212 children aged between 2 and 60 months, 199 of whom had complete records at two study drug shops in south western Uganda participated in the study. Duplicate 5 μL samples of capillary blood were picked from the 212 children, dispensed onto the sample well of the CareStart™ Pf-HRP2 RDT cassette and a FTA, Whatman™ 3MM filter paper in parallel. The RDT strip was interpreted by the drug seller within 15–20 min, visually re-read centrally by laboratory scientist and from it; Plasmodium DNA was recovered and detected by PCR, and compared with FTA recovered P. falciparum DNA PCR detection. Results Malaria positive samples were 62/199 (31.2%, 95% CI 24.9, 38.3) by drug seller interpretation of RDT strip, 59/212 (27.8%, 95% CI 22.2, 34.3) by laboratory scientist, 55/212 (25.9%, 95% CI 20.0, 32.6) by RDT nitrocellulose strip PCR and 64/212 (30.2%, 95% CI 24.4, 37.7). The overall agreement between the drug seller interpretation and laboratory scientist re-reading of the RDT strip was 93.0% with kappa value of 0.84 (95% CI 0.75, 0.92). The drug seller compliance with the reported RDT results was 92.5%. The performance of the three diagnostic strategies compared with FTA-PCR as the gold standard had sensitivity between 76.6 and 86.9%, specificity above 90%, positive predictive values ranging from 79.0 to 89.8% and negative predictive values above 90%. Conclusion Drug sellers can use RDTs in field conditions and achieve acceptable accuracy for malaria diagnosis, and they comply with the RDT results. Plasmodium DNA can be recovered from RDT nitrocellulose strips even in the context of drug shops. Future malaria surveillance and diagnostic quality control studies with RDT cassette as a source of Plasmodium DNA are recommended.

Misuse of Artemisinin Combination Therapies by Clients of Medicine Retailers Suspected to Have Malaria Without Prior Parasitological Confirmation in Nigeria. Int J Health Policy Manag 2018; 7:542-548. [PMID: 29935131 PMCID: PMC6015511 DOI: 10.15171/ijhpm.2017.122] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2016] [Accepted: 10/06/2017] [Indexed: 12/05/2022] Open
Abstract
Background: Prompt and effective case detection and treatment are vital components of the malaria case management strategy as malaria-endemic countries implement the testing, treating and tracking policy. The implementation of this policy in public and formal private sectors continue to receive great attention while the informal private retail sector (mostly the patent and propriety medicine vendors [PPMVs]) where about 60% of patients with fever in Nigeria seek treatment is yet to be fully integrated. The PPMVs sell artemisinin combination therapies (ACTs) without prior testing and are highly patronized. Without prior testing, malaria is likely to be over-treated. The need to expand access to diagnosis in the huge informal private health sector among PPMVs is currently being explored to ensure that clients that patronize retail drug stores are tested before sales of ACTs.
Methods: A cross-sectional multistage study was conducted among 1279 adult clients, 20 years and above, who purchased malaria medicines from 119 selected PPMVs in five administrative areas (States) of Nigeria, namely: Adamawa, Cross River, Enugu, Lagos and Kaduna, as well as the Federal Capital Territory, Abuja. Exit interviews using a standard case report questionnaire was conducted after the purchase of the antimalarial medicine and thick/thin blood smears from the clients’ finger-prick were prepared to confirm malaria by expert microscopy.
Results: Of the 1279 clients who purchased malaria medicines from the PPMV outlets, 107 (8.4%) were confirmed to have malaria parasites. The malaria prevalence in the various study areas ranged from 3.5% to 16%. A high proportion of clients in the various study sites who had no need for malaria medicines (84%-96.5%) purchased and used antimalarial medicines from the PPMVs. This indicated a high level of over-treatment and misuse of antimalarials. Common symptoms that are widely used as indicators for malaria such as, fever, headache, and tiredness were not significantly associated with malaria. Nausea/vomiting, poor appetite, chills, bitter taste in the mouth and dark urine were symptoms that were significantly associated with malaria among the adult clients (P<.05) but not fever (P=.06).
Conclusion: Misuse of ACTs following overtreatment of malaria based on clinical diagnosis occurs when suspected cases of malaria are not prior confirmed with a test. Non-testing before sales of malaria medicines by PPMVs will perpetuate ACT misuse with the patients not benefiting due to poor treatment outcomes, waste of medicines and financial loss from out-of-pocket payment for unneeded medicines.

Abstract
BACKGROUND Rapid diagnostic test (RDT) positivity is supplanting microscopy as the standard measure of malaria burden at the population level. However, there is currently no standard for externally validating RDT results from field surveys. METHODS Individuals' blood concentration of the Plasmodium falciparum histidine rich protein 2 (HRP2) protein were compared to results of HRP2-detecting RDTs in participants from field surveys in Angola, Mozambique, Haiti, and Senegal. A logistic regression model was used to estimate the HRP2 concentrations corresponding to the 50 and 90% level of detection (LOD) specific for each survey. RESULTS There was a sigmoidal dose-response relationship between HRP2 concentration and RDT positivity for all surveys. Variation was noted in estimates for field RDT sensitivity, with the 50% LOD ranging between 0.076 and 6.1 ng/mL and the 90% LOD ranging between 1.1 and 53 ng/mL. Surveys conducted in two different provinces of Angola using the same brand of RDT and same study methodology showed a threefold difference in LOD. CONCLUSIONS Measures of malaria prevalence estimated using population RDT positivity should be interpreted in the context of potentially large variation in RDT LODs between, and even within, surveys. Surveys based on RDT positivity would benefit from external validation of field RDT results by comparing RDT positivity and antigen concentration.

Abstract
BACKGROUND Deployment of sound diagnostic tests remains a crucial component of malaria management, prevention and control in Africa. We undertook a comparative assessment of sensitivity, specificity and efficiency of three popular brands of rapid diagnostic tests (RDT) available in Nigerian market alongside with traditional microscopy. MATERIALS AND METHODS 525 samples of patients that presented with acute uncomplicated malaria through clinical diagnosis were evaluated with the various tests. Total WBC count and haematocrit were also measured. RESULTS Of the 525 samples, 300 (57.1%) were found positive by Giemsa microscopy. SD Bioline had a positivity rate of 49.5% (260/525), while the positivity rate for Acon was significantly lower (38.1%; 200/525) and Paracheck (28.6%; 150/525). The sensitivity, specificity and efficiency of the three RDTs were: SD Bioline (86.3%, 99.6%, 92%); Paracheck (50%, 97.7%, 70.4%) and Acon (66.7%, 100%, 80.9%), respectively. Pre-teens aged 6-12 yrs had the highest mean malaria parasite densities with 6,631.26 at p< 0.01. The dominant malaria species was Plasmodium falciparum with 280 (93.3%) cases. Co-infections of P. falciparum/vivax (15; 5.0%) and P. falciparum/malariae (5; 1.7%) were detected and confirmed with microscopy. Haematocrit values correlated inversely with parasite density (r = -0.744; p< 0.01). CONCLUSIONS Microscopy still remains the reference standard for malaria diagnosis in limited resource settings in endemic areas. In furtherance to this, there is need for consistent monitoring of RDT product quality as part of the distribution process to end-users across Nigeria.

Abstract
Background Artemisinin-based combination therapy (ACT) is recommended as the first-line anti-malarial treatment strategy in sub-Saharan African countries. WHO policy recommends parasitological confirmation by microscopy or rapid diagnostic test (RDT) in all cases of suspected malaria prior to treatment. Gaps remain in understanding the factors that influence patient treatment-seeking behaviour and anti-malarial drug purchase decisions in the private sector. The objective of this study was to identify patient treatment-seeking behaviour in Ghana, Kenya, Nigeria, Tanzania, and Uganda. Methods Face-to-face patient interviews were conducted at a total of 208 randomly selected retail outlets in five countries. At each outlet, exit interviews were conducted with five patients who indicated they had come seeking anti-malarial treatment. The questionnaire was anonymous and standardized in the five countries and collected data on different factors, including socio-demographic characteristics, history of illness, diagnostic practices (i.e. microscopy or RDT), prescription practices and treatment purchase. The price paid for the treatment was also collected from the outlet vendor. Results A total of 994 patients were included from the five countries. Location of malaria diagnosis was significantly different in the five countries. A total of 484 blood diagnostic tests were performed, (72.3% with microscopy and 27.7% with RDT). ACTs were purchased by 72.5% of patients who had undergone blood testing and 86.5% of patients without a blood test, regardless of whether the test result was positive or negative (p < 10−4). A total of 531 patients (53.4%) had an anti-malarial drug prescription, of which 82.9% were prescriptions for an ACT. There were significant differences in prescriptions by country. A total of 923 patients (92.9%) purchased anti-malarial drugs in an outlet, including 79.1% of patients purchasing an ACT drug: 98.0% in Ghana, 90.5% in Kenya, 80.4% in Nigeria, 69.2% in Tanzania, and 57.7% in Uganda (p < 10−4). Having a drug prescription was not a significant predictive factor associated with an ACT drug purchase (except in Kenya). The number of ACT drugs purchased with a prescription was greater than the number purchased without a prescription in Kenya, Nigeria and Tanzania. Conclusions This study highlights differences in drug prescription and purchase patterns in five sub-Saharan African countries. The private sector is playing an increasingly important role in fever case management in sub-Saharan Africa. Understanding the characteristics of private retail outlets and the role they play in providing anti-malaria drugs may support the design of effective malaria interventions.

Abstract
BACKGROUND In malaria elimination settings, all malaria cases must be identified, documented and investigated. To facilitate complete and timely reporting of all malaria cases and effective case management and follow-up, engagement with private providers is essential, particularly in settings where the private sector is a major source of healthcare. However, research on the role and performance of the private sector in malaria diagnosis, case management and reporting in malaria elimination settings is limited. Moreover, the most effective strategies for private sector engagement in malaria elimination settings remain unclear. METHODS Twenty-five experts in malaria elimination, disease surveillance and private sector engagement were purposively sampled and interviewed. An extensive review of grey and peer-reviewed literature on private sector testing, treatment, and reporting for malaria was performed. Additional in-depth literature review was conducted for six case studies on eliminating and neighbouring countries in Southeast Asia and Southern Africa. RESULTS The private health sector can be categorized based on their commercial orientation or business model (for-profit versus nonprofit) and their regulation status within a country (formal vs informal). A number of potentially effective strategies exist for engaging the private sector. Conducting a baseline assessment of the private sector is critical to understanding its composition, size, geographical distribution and quality of services provided. Facilitating reporting, referral and training linkages between the public and private sectors and making malaria a notifiable disease are important strategies to improve private sector involvement in malaria surveillance. Financial incentives for uptake of rapid diagnostic tests and artemisinin-based combination therapy should be combined with training and community awareness campaigns for improving uptake. Private sector providers can also be organized and better engaged through social franchising, effective regulation, professional organizations and government outreach. CONCLUSION This review highlights the importance of engaging private sector stakeholders early and often in the development of malaria elimination strategies.

Malar J 2017; 16:231. [PMID: 28569154 PMCID: PMC5452350 DOI: 10.1186/s12936-017-1880-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Accepted: 05/26/2017] [Indexed: 11/17/2022] Open
Abstract
Background The national strategy against malaria in an endemic country should involve all the health stakeholders. In Benin, the private sector is rarely present in the activities of the National Malaria Control Programme (NMCP), and its surveillance system does not cover private sector outlets that are a non-negligible part of the healthcare system. Objective The aim of this study was to describe the drug delivery practices within private pharmacies of Cotonou and Porto-Novo and the awareness of medicine providers concerning the national policy of malaria treatment. Methods A survey was performed among pharmacy staff members responsible for dispensing medicines and providing advice to patients within pharmacies of Cotonou and Porto-Novo. Dispensing/pharmacy assistants (‘dispensators’) from 82 pharmacies in Cotonou and 19 in Porto-Novo were surveyed. Data entry was performed using Epidata 3.1 software and data analysis was carried out using SPSS software version 21.1. Chi square test was used to compare proportions. A significance threshold of 0.05 was defined for the p value. Results 46% of providers did not know the artemisinin-based combination therapy recommended by the NMCP for treating uncomplicated malaria. 58.7% were not able to recognize the gravity signs of malaria. 89.8% of dispensators were used to deliver an anti-malarial upon patient request, without prior biological confirmation as requested by the NMCP policy. Conclusions Dispensing practices within the studied pharmacies from Cotonou and Porto-Novo were not in adequacy with the NMCP guidelines for uncomplicated malaria, which is a striking weakness in the training of drug providers on key elements of the guidelines for managing malaria. The NMCP needs to help dispensator from private pharmacies sector to standardize drug delivery practices according to its guidelines.

Boyce MR, O'Meara WP. Use of malaria RDTs in various health contexts across sub-Saharan Africa: a systematic review. BMC Public Health 2017; 17:470. [PMID: 28521798 PMCID: PMC5437623 DOI: 10.1186/s12889-017-4398-1] [Citation(s) in RCA: 74] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2016] [Accepted: 05/08/2017] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND The World Health Organization recommends parasitological confirmation of malaria prior to treatment. Malaria rapid diagnostic tests (RDTs) represent one diagnostic method that is used in a variety of contexts to overcome limitations of other diagnostic techniques. Malaria RDTs increase the availability and feasibility of accurate diagnosis and may result in improved quality of care. Though RDTs are used in a variety of contexts, no studies have compared how well or effectively RDTs are used across these contexts. This review assesses the diagnostic use of RDTs in four different contexts: health facilities, the community, drug shops and schools. METHODS A comprehensive search of the Pubmed database was conducted to evaluate RDT execution, test accuracy, or adherence to test results in sub-Saharan Africa. Original RDT and Plasmodium falciparum focused studies conducted in formal health care facilities, drug shops, schools, or by CHWs between the year 2000 and December 2016 were included. Studies were excluded if they were conducted exclusively in a research laboratory setting, where staff from the study team conducted RDTs, or in settings outside of sub-Saharan Africa. RESULTS The literature search identified 757 reports. A total of 52 studies were included in the analysis. Overall, RDTs were performed safely and effectively by community health workers provided they receive proper training. Analogous information was largely absent for formal health care workers. Tests were generally accurate across contexts, except for in drug shops where lower specificities were observed. Adherence to RDT results was higher among drug shop vendors and community health workers, while adherence was more variable among formal health care workers, most notably with negative test results. CONCLUSIONS Malaria RDTs are generally used well, though compliance with test results is variable - especially in the formal health care sector. If low adherence rates are extrapolated, thousands of patients may be incorrectly diagnosed and receive inappropriate treatment resulting in a low quality of care and unnecessary drug use. Multidisciplinary research should continue to explore determinants of good RDT use, and seek to better understand how to support and sustain the correct use of this diagnostic tool.

A cross-sectional study of the availability and price of anti-malarial medicines and malaria rapid diagnostic tests in private sector retail drug outlets in rural Western Kenya, 2013. Malar J 2016; 15:359. [PMID: 27406179 PMCID: PMC4942924 DOI: 10.1186/s12936-016-1404-5] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2016] [Accepted: 06/17/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Although anti-malarial medicines are free in Kenyan public health facilities, patients often seek treatment from private sector retail drug outlets. In mid-2010, the Affordable Medicines Facility-malaria (AMFm) was introduced to make quality-assured artemisinin-based combination therapy (ACT) accessible and affordable in private and public sectors. METHODS Private sector retail drug outlets stocking anti-malarial medications within a surveillance area of approximately 220,000 people in a malaria perennial high-transmission area in rural western Kenya were identified via a census in September 2013. A cross-sectional study was conducted in September-October 2013 to determine availability and price of anti-malarial medicines and malaria rapid diagnostic tests (RDTs) in drug outlets. A standardized questionnaire was administered to collect drug outlet and personnel characteristics and availability and price of anti-malarials and RDTs. RESULTS Of 181 drug outlets identified, 179 (99 %) participated in the survey. Thirteen percent were registered pharmacies, 25 % informal drug shops, 46 % general shops, 13 % homesteads and 2 % other. One hundred sixty-five (92 %) had at least one ACT type: 162 (91 %) had recommended first-line artemether-lumefantrine (AL), 22 (12 %) had recommended second-line dihydroartemisinin-piperaquine (DHA-PPQ), 85 (48 %) had sulfadoxine-pyrimethamine (SP), 60 (34 %) had any quinine (QN) formulation, and 14 (8 %) had amodiaquine (AQ) monotherapy. The mean price (range) of an adult treatment course for AL was $1.01 ($0.35-4.71); DHA-PPQ was $4.39 ($0.71-7.06); QN tablets were $2.24 ($0.12-4.71); SP was $0.62 ($0.24-2.35); AQ monotherapy was $0.42 ($0.24-1.06). The mean AL price with or without the AMFm logo did not differ significantly ($1.01 and 1.07, respectively; p = 0.45). Only 17 (10 %) drug outlets had RDTs; 149 (84 %) never stocked RDTs. The mean RDT price was $0.92 ($0.24-2.35). CONCLUSIONS Most outlets never stocked RDTs; therefore, testing prior to treatment was unlikely for customers seeking treatment in the private retail sector. The recommended first-line treatment, AL, was widely available. Although SP and AQ monotherapy are not recommended for treatment, both were less expensive than AL, which might have caused preferential use by customers. Interventions that create community demand for malaria diagnostic testing prior to treatment and that increase RDT availability should be encouraged.

Abstract
Most patients with suspected malaria do not receive diagnostic confirmation before beginning antimalarial treatment. We investigated the extent to which uncertainty about malaria diagnosis contributes to patient nonadherence to artemether-lumefantrine (AL) treatment through a randomized controlled trial in central Uganda. Among 1,525 patients purchasing a course of AL at private drug shops, we randomly offered 37.6% a free malaria rapid diagnostic test (RDT) and then assessed adherence through home visits 3 days later. Of these subjects, 68.4% tested positive for malaria and 65.8% adhered overall. Patients who tested positive did not have significantly higher odds of adherence than those who were not offered the test (adjusted odds ratio [OR]: 1.07, 95% confidence interval [CI]: 0.734-1.57,P= 0.719). Patients who received a positive malaria test had 0.488 fewer pills remaining than those not offered the test (95% CI: -1.02 to 0.043,P= 0.072). We found that patients who felt relatively healthy by the second day of treatment had lower odds of completing treatment (adjusted OR: 0.532, 95% CI: 0.394-0.719,P< 0.001). Our results suggest that diagnostic testing may not improve artemisinin-based combination therapy adherence unless efforts are made to persuade patients to continue taking the full course of drugs even if symptoms have resolved.

Abstract
Objectives To characterise the differences in care seeking behaviour and dispensing outcomes between adults and children purchasing drugs for malaria at retail shops in Nigeria. Methods In Nasarawa State, retail drug shops were enumerated and a subset of those stocking antimalarials were selected as study sites and surveyed. Customers exiting shops after purchasing antimalarial drugs were surveyed and tested with a malaria rapid diagnostic test. Sick adults and caregivers accompanying sick children were eligible, but individuals purchasing drugs for a sick person that was not present were excluded. Multivariate regression analysis was used to identify the correlates of care seeking and the quality of interaction at the shop. Results Of 737 participants, 80% were adults and 20% were children (under age 18). Caregivers of sick children were more likely to obtain a prescription prior to attending a drug retailer than adults seeking care for themselves and waited a shorter time before seeking care. Caregivers of sick children were also more likely than sick adults to have been asked about symptoms by the retailer, to have been given an examination, and to have purchased an ACT. Fewer than half of respondents had purchased an ACT. Only 14% of adults, but 27% of children were RDT-positive; RDT-positive children were more likely to have had an ACT purchased for them than RDT-positive adults. Conclusions Children with suspected malaria tend to receive better care at drug retailers than adults. The degree of overtreatment and prevalence of dispensing non-recommended antimalarials emphasise the need for routine diagnosis before treatment to properly treat both malaria and non-malaria illnesses.

Abstract
BACKGROUND In Uganda, as in most other malaria-endemic countries, presumptive treatment for malaria based on symptoms without a diagnostic blood test is still very common. While diagnostic testing in public sector facilities is increasing, many people in Uganda who suspect malaria visit private sector outlets to purchase medications. Increasing the availability and uptake of rapid diagnostic tests (RDTs) for malaria in private outlets could help increase diagnostic testing for malaria but raises questions about the patient demand for and valuation of testing that are less critical for public sector introduction. METHODS In preparation for a behaviour change campaign to encourage and sustain the demand for RDTs in drug shops, eight focus group discussions with a total of 84 community members were conducted in six districts across Uganda's Eastern Region in November-December 2011. Focus groups explored incentives and barriers to seeking diagnosis for malaria, how people react to test results and why, and what can be done to increase the willingness to pay for RDTs. RESULTS Overall, participants were very familiar with malaria diagnostic testing and understood its importance, yet when faced with limited financial resources, patients preferred to spend their money on medication and sought testing only when presumptive treatment proved ineffective. While side effects did seem to be a concern, participants did not mention other potential costs of taking unnecessary or ineffective medications, such as money wasted on excess drugs or delays in resolution of symptoms. Very few individuals were familiar with RDTs. CONCLUSION In order to boost demand, these results suggest that private sector RDTs will have to be made convenient and affordable and that targeted behaviour change campaigns should strive to increase the perceived value of diagnosis.

Abstract
Background Rapid diagnostic tests (RDTs) are now widely used for laboratory confirmation of suspected malaria cases to comply with the World Health Organization recommendation for universal testing before treatment. However, many malaria programmes lack quality control (QC) processes to assess RDT use under field conditions. Prior research showed the feasibility of using the dried tube specimen (DTS) method for preserving Plasmodium falciparum parasites for use as QC samples for RDTs. This study focused on the use of DTS for RDT QC and proficiency testing under field conditions. Methods DTS were prepared using cultured P. falciparum at densities of 500 and 1,000 parasites/μL; 50 μL aliquots of these along with parasite negative human blood controls (0 parasites/μL) were air-dried in specimen tubes and reactivity verified after rehydration. The DTS were used in a field study in the Oromia Region of Ethiopia. Replicate DTS samples containing 0, 500 and 1,000 parasites/μL were stored at 4°C at a reference laboratory and at ambient temperatures at two nearby health facilities. At weeks 0, 4, 8, 12, 16, 20, and 24, the DTS were rehydrated and tested on RDTs stored under manufacturer-recommended temperatures at the RL and on RDTs stored under site-specific conditions at the two health facilities. Reactivity of DTS stored at 4°C at the reference laboratory on RDTs stored at the reference laboratory was considered the gold standard for assessing DTS stability. A proficiency-testing panel consisting of one negative and three positive samples, monitored with a checklist was administered at weeks 12 and 24. Results At all the seven time points, DTS stored at both the reference laboratory and health facility were reactive on RDTs stored under the recommended temperature and under field conditions, and the DTS without malaria parasites were negative. At the reference laboratory and one health facility, a 500 parasites/μL DTS from the proficiency panel was falsely reported as negative at week 24 due to errors in interpreting faint test lines. Conclusions The DTS method can be used under field conditions to supplement other RDT QC methods and health worker proficiency in Ethiopia and possibly other malaria-endemic countries.

Abstract
Background Despite substantial investments made over the past 40 years in low income countries, governments cannot be viewed as the principal health care provider in many countries. Evidence on the role of the private sector in the delivery of health services is becoming increasingly available. In this study, we set out to determine the extent to which the private sector has been utilized in providing integrated care for sick children under 5 years of age with community–acquired malaria, pneumonia or diarrhoea. Methods We reviewed the published literature for integrated community case management (iCCM) related experiences within both the public and private sector. We searched PubMed and Google/Google Scholar for all relevant literature until July 2014. The search terms used were “malaria”, “pneumonia”, “diarrhoea”, “private sector” and “community case management”. Results A total of 383 articles referred to malaria, pneumonia or diarrhoea in the private sector. The large majority of these studies (290) were only malaria related. Most of the iCCM–related studies evaluated introduction of only malaria drugs and/or diagnostics into the private sector. Only one study evaluated the introduction of drugs and diagnostics for malaria, pneumonia and diarrhoea in the private sector. In contrast, most iCCM–related studies in the public sector directly reported on community case management of 2 or more of the illnesses. Conclusions While the private sector is an important source of care for children in low income countries, little has been done to harness the potential of this sector in improving access to care for non–malaria–associated fever in children within the community. It would be logical for iCCM programs to expand their activities to include the private sector to achieve higher population coverage. An implementation research agenda for private sector integrated care of febrile childhood illness needs to be developed and implemented in conjunction with private sector intervention programs.
