Misuse of Artemisinin Combination Therapies by Clients of Medicine Retailers Suspected to Have Malaria Without Prior Parasitological Confirmation in Nigeria

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

Psychosocial factors associated with racial disparities in exclusive breastfeeding

Despite the well-documented benefits of exclusive breastfeeding, many child-bearing people wean their infants before the recommended six months. Black child-bearing people exclusively breastfeed for a shorter time than people of other racial and ethnic groups. The reasons for these continued breastfeeding disparities are unclear; therefore, it is crucial to examine how psychosocial factors contribute to this disparity. This dissertation compared exclusive breastfeeding rates obtained from the 24-hour recall and the since birth methods and estimated the magnitude of difference between both across race and demographic characteristics. I examined the influence of psychosocial factors such as perceived stress, perceived and received social support, racial and gender discrimination, and microaggressions on exclusive breastfeeding. Data were derived from a National Heart, Lung, and Blood Institute (NHLBI) funded study (Postpartum Mobile Mothers Study -PMOMS) collected using ecological momentary assessment (EMA) for 12 months postpartum. The analyses included: 1) Mixed-effects logistic regression model with random intercepts to establish the relationship between perceived stress, social support, and exclusive breastfeeding; 2) Generalized structural equation modeling to test the hypothesized pathway through which racial and gender discrimination and microaggression would directly or indirectly influence exclusive breastfeeding through perceived stress. The 24-hour recall exclusive breastfeeding rates were higher across the first six months postpartum than the since birth exclusive breastfeeding rates. Participants who reported higher perceived stress were less likely to breastfeed exclusively for six months. Perception of social support moderated the relationship between perceived stress and breastfeeding. In contrast, receiving social support did not moderate the relationship between perceived stress and exclusive breastfeeding but directly increased the likelihood of exclusive breastfeeding. Black participants were less likely to exclusively breastfeed in the study. Perceived stress mediated the relationship between microaggressions and exclusive breastfeeding such that microaggressions increased stress, which in turn reduced the likelihood of exclusive breastfeeding. This study shows that racial differences, stress, social support, and microaggressions influence exclusive breastfeeding and may contribute to the racial disparities observed in exclusive breastfeeding rates. Addressing these factors would improve exclusive breastfeeding rates among child-bearing people and bridge the racial gap

Demand-related factors influencing caregivers' awareness of malaria tests and health workers' testing practices, in Makarfi, Nigeria.

BackgroundDespite the World Health Organization's recommendation of malaria test-treat strategy, which is the treatment of parasitological confirmed malaria cases with anti-malarials, presumptive diagnosis of malaria remains fairly common in Nigeria. The reasons for this have not been established in Makarfi, Nigeria, despite the high burden of malaria in the area. A study was conducted among caregivers of febrile children less than 5&nbsp;years presenting for treatment to understand their awareness of malaria diagnostic testing and being offered testing by clinicians, the determinants of these outcomes, and caregivers' perspectives of health workers' testing practices.MethodsUsing mixed-methods, data was combined from sub-analysis of cross-sectional survey data (n&nbsp;=&nbsp;295) and focus group discussions (n&nbsp;=&nbsp;4) with caregivers conducted in Makarfi General Hospital (Kaduna State, Nigeria) and surrounding communities in 2011. Bivariate and multivariate analysis of the quantitative survey data was conducted to examine associations of caregivers' sociodemographic characteristics with testing awareness and having ever been offered testing. Transcripts from focus group discussions (FGD) were analysed for emerging themes related to caregivers' perspectives on malaria testing.ResultsAmong surveyed caregivers who were predominantly female (81.7%), not formally educated (72.5%), and were housewives (68.8%); only 5.3% were aware of any diagnostic testing for malaria, and only 4.3% had ever been offered a malaria test by a health worker. Having at least a primary level education (adjusted odds ratio [aOR] 20.3, 95% CI 4.5-92.1) and living within 5&nbsp;km of the hospital (aOR 4.3, 95% CI 1.5-12.5) were determinants of awareness of malaria testing. Also, these were determinants of previously having been offered a test (aOR 9.9, 95% CI 2.1-48.7; and aOR 4.0, 95% CI 1.1-14.7). FGD showed many caregivers believed that malaria testing was for severe illness only, and that proximity to a health facility and cost of treatment influenced the seeking and receiving of care.ConclusionsUptake of malaria testing prior to treatment can be improved by increasing its awareness and addressing misunderstandings among caregivers, promoting testing practices among health workers, and availing caregivers living farther from health centres alternative opportunities for community case management of febrile illnesses

The role of drug vendors in improving basic health-care services in Nigeria.

ObjectiveTo characterize patent and proprietary medicine vendors and shops in Nigeria and to assess their ability to help improve access to high-quality, primary health-care services.MethodsIn 2013 and 2014, a census of patent and proprietary medicine shops in 16 states of Nigeria was carried out to determine: (i) the size and coverage of the sector; (ii) the basic characteristics of shops and their staff; and (iii) the range of products stocked for priority health services, particularly for malaria, diarrhoea and family planning. The influence of the medical training of people in charge of the shops on the health-care products stocked and registration with official bodies was assessed by regression analysis.FindingsThe number of shops per 100,000 population was higher in southern than in northern states, but the average percentage of people in charge with medical training across local government areas was higher in northern states: 52.6% versus 29.7% in southern states. Shops headed by a person with medical training were significantly more likely to stock artemisinin-based combination therapy, oral rehydration salts, zinc, injectable contraceptives and intrauterine contraceptive devices. However, these shops were less likely to be registered with the National Association of Patent and Proprietary Medicine Dealers and more likely to be registered with the regulatory body, the Pharmacist Council of Nigeria.ConclusionMany patent and proprietary medicine vendors in Nigeria were medically trained. With additional training and oversight, they could help improve access to basic health-care services. Specifically, vendors with medical training could participate in task-shifting interventions

Presumptive treatment of malaria from formal and informal drug vendors in Nigeria.

BACKGROUND: Despite policies that recommend parasitological testing before treatment for malaria, presumptive treatment remains widespread in Nigeria. The majority of Nigerians obtain antimalarial drugs from two types of for-profit drug vendors-formal and informal medicine shops-but little is known about the quality of malaria care services provided at these shops. AIMS: This study seeks to (1) describe the profile of patients who seek treatment at different types of drug outlets, (2) document the types of drugs purchased for treating malaria, (3) assess which patients are purchasing recommended drugs, and (4) estimate the extent of malaria over-treatment. METHODS: In urban, peri-urban, and rural areas in Oyo State, customers exiting proprietary and patent medicine vendor (PPMV) shops or pharmacies having purchased anti-malarial drugs were surveyed and tested with malaria rapid diagnostic test. A follow-up phone survey was conducted four days after to assess self-reported drug administration. Bivariate and multivariate regression analysis was conducted to determine the correlates of patronizing a PPMV versus pharmacy, and the likelihood of purchasing an artemisinin-combination therapy (ACT) drug. RESULTS: Of the 457 participants who sought malaria treatment in 49 enrolled outlets, nearly 92% had diagnosed their condition by themselves, a family member, or a friend. Nearly 60% pharmacy customers purchased an ACT compared to only 29% of PPMV customers, and pharmacy customers paid significantly more on average. Multivariate regression results show that patrons of PPMVs were younger, less wealthy, waited fewer days before seeking care, and were less likely to be diagnosed at a hospital, clinic, or laboratory. Only 3.9% of participants tested positive with a malaria rapid diagnostic test. CONCLUSIONS: Poorer individuals seeking care at PPMVs are more likely to receive inappropriate malaria treatment when compared to those who go to pharmacies. Increasing accessibility to reliable diagnosis should be explored to reduce malaria over-treatment
