Improving access to appropriate case management for common childhood illnesses in hard-to-reach areas of Abia State, Nigeria

# Background Studies have demonstrated that trained community health workers can improve access to quality health services for under five children. Under the World Health Organization's Rapid Access Expansion Progamme, integrated community case management of childhood illnesses (iCCM) was introduced in Abia and Niger States, Nigeria in 2013. The objective of the program was to increase the number of children 2-59 months receiving quality life-saving treatment for malaria, pneumonia and diarrhoea by extending case management through community-oriented resource persons (CORPs). We present findings from household surveys comparing baseline and endline data to assess changes in sick child care-seeking, assessment, and treatment coverage provided over the project period in Abia State. # Methods A baseline household survey was conducted in May 2014 and an endline survey in February 2017. The surveys used multi-stage cluster sampling of primary caregivers of children aged 2-59 months who had been recently sick with diarrhoea, fever, or cough with difficult breathing. # Results Care-seeking from an appropriate provider improved significantly from 69% at baseline to 77% at endline (*P*\<0.01). At baseline, patent and proprietary medicine vendors (PPMVs) (55%) and health centers (34%) were the main providers of care for iCCM services; by endline, CORPs became the main source (48%), followed by PPMVs (36%) and health centers (25%). # Conclusions Overall, the findings demonstrate improvements in care-seeking. Care-seeking practices shifted over the course of the project, with more caregivers seeking care from CORPs by the end of the project. The findings suggest that scaling up iCCM in Nigeria may improve access to appropriate treatment for under five children living in hard-to-reach areas.

Using 'Theories of Change' and responsive feedback to design a digital service business for patent and proprietary medicine vendors in Nigeria.

In a paper titled "Responsive feedback: Towards a new paradigm to enhance intervention effectiveness", Viswanath et al. argue that dominant models of intervention design do not account for the complexity and unpredictability of implementation challenges. Particularly in the behavioural sciences, intervention designs need to consider many factors that will be uncertain, or unknown, at the beginning of a new project. This letter describes how we were able to respond to feedback during the design phase of a proof-of-concept project to create a digital service business for Nigerian patent and proprietary medicine vendors (PPMVs). Our approach was to create an initial 'Theory of Change' (ToC) based on a similar project with Kenyan shopkeepers. This ToC was revised following user feedback and a landscape analysis with key stakeholders. The new ToC required us to access additional funding to create a 'digital ordering' facility for the PPMVs. Digital ordering provides a mechanism whereby we can reduce the prevalence of counterfeit medicines, offer the PPMVs credit and group-buying facilities, and reduce supply chain costs through co-distribution with fast-moving consumer goods. An important learning point was that while our focus was on designing a platform to meet users' needs, changes in regulation meant that we spent considerably more time than anticipated meeting the needs of multiple stakeholders. However, the importance of ensuring stakeholders' continued buy-in cannot be underestimated and has likely increased the sustainability of the project in the longer term. As Viswanath et al. suggest, for responsive approaches to be widely adopted needs more flexibility than exists in current funding models and project plans. Both funding bodies and grantees will need to be more responsive to feedback coming from the field.

Malaria testing and treatment knowledge among selected rural patent and proprietary medicine vendors (PPMV) in Nigeria

BackgroundMalaria is a leading cause of illness and death in Nigeria, but access of poor people to quality anti-malarial services remains low especially in the rural areas. Patent and proprietary medicine vendors (PPMVs) provide the majority of malaria treatment in rural areas, but little is known about their knowledge of malaria testing and treatment of uncomplicated malaria as recommended in the 2011 National Malaria Control Programme policy.MethodsA cross-sectional survey was conducted in two purposively selected states (Oyo and Bayelsa) in Nigeria with each state representing a different geographic and linguistic–ethnic region in the southern part of the country. Two rural LGAs were randomly selected from each state and data were collected from 160 randomly selected PPMVS (40 per LGA) using a structured questionnaire. Data were analysed using descriptive statistics.ResultsThe 2011 National Policy on Malaria Diagnosis and Treatment is mostly unknown to PPMVs. Although most PPMVs (89%) knew that artemisinin-based combination therapy (ACT) is recommended in the national policy, 91% also thought non-ACT were endorsed. The proportion of PPMVs who stated they would treat a malaria case with an artemisinin-based combination at the correct dose was 33% for a child under five, 47% for an adult male and 14% for a pregnant woman in her second trimester. The proportion of PPMVs who reported they would diagnose a case of malaria prior to treatment using a malaria rapid diagnostic test (RDT) kit was 1.9% for children under five, 7.5% for adult males and 3.1% for pregnant women in their first trimester due to lack of knowledge. Almost two-thirds (65.6%) would correctly refer children with severe malaria to health facility.ConclusionsSubstantial knowledge gaps on the use of RDTs and treatment with artemisinin-based combinations exist among rural PPMVs. Given existing evidence regarding the effectiveness of private retail outlets in malaria case management, PPMVs should be provided with competency-based training and supervision to improve the quality of care they provide.

Preference for Artemisinin\u2013based combination therapy among healthcare providers, Lokoja, North-Central Nigeria

BackgroundIn Nigeria, Artemisinin-based Combination Therapy (ACT) is the recommended first line antimalarial medicine for uncomplicated malaria. However, health care providers still continue the use of less efficacious medicines such as Sulphadoxine-pyrimethamine and chloroquine. We therefore determined preference for ACT (PFA) and factors associated with PFA among healthcare providers (HCP) in Lokoja, North-Central Nigeria as well as assessed healthcare providers’ knowledge of malaria case management.MethodsWe conducted a cross-sectional study among physicians, nurses, pharmacists, community health officers (CHOs), community health extension workers (CHEWs) and, patent and proprietary medicine vendors (PPMVs). Interviewer-administered questionnaires were administered to collect data on respondents’ characteristics, previously received malaria case management training and knowledge of malaria treatment. Knowledge scores ≥3 were categorised as good, maximum obtainable being 5.ResultsOf the 404 respondents, 214 (53.0%) were males. Overall, 219 (54.2%) respondents who received malaria case management training included PPMVs: 79 (65.8%), CHEWs: 25 (64.1%), CHOs: 5 (55.6%), nurses: 72 (48.7%), physicians: 35 (47.3%) and pharmacists: 3 (23.1%). Overall, 202 (50.0%) providers including physicians: 69 (93.2%), CHO: 8 (88.9%), CHEWs: 33 (84.6%), pharmacists: 8 (61.5%), nurses: 64 (43.2%) and PPMVs: 20 (16.5%), had good knowledge of malaria treatment guidelines. Overall, preference for ACT among healthcare providers was 39.6%. Physicians: 50 (67.6%), pharmacists: 7 (59.3%) CHOs: 5 (55.6%), CHEWS: 16 (41.0%), nurses: 56 (37.8%) and PPMV: 24 (19.8%) had PFA. Receiving malaria case management training (adjusted odds ratio [aOR]) = 2.3; CI = 1.4 – 3.7) and having good knowledge of malaria treatment (aOR = 4.0; CI = 2.4 – 6.7) were associated with PFA.ConclusionsOverall preference for ACT use was low among health care providers in this study. Preference for ACTs and proportion of health workers with good knowledge of malaria case management were even lower among PPMVs who had highest proportion of those who received malaria case management training. We recommend evaluation of current training quality, enhanced targeted training, follow-up supportive supervision of PPMVs and behavior change communication on ACT use.

Feasibility of patent and proprietary medicine vendor provision of injectable contraceptives: preliminary results from implementation science research in Oyo and Nasarawa, Nigeria

BackgroundNigerian policymakers are debating task-shifting injectable contraceptive services to Patent and Proprietary Medicine Vendors (PPMVs). MethodologyOne hundred fifty-two PPMVs were trained to provide injectable contraceptives in Oyo and Nasarawa states. Data were collected before and 1, 3 and 9 months posttraining. χ2 tests were conducted to assess associations between survey time points. Main findingsFew PPMVs had the necessary knowledge to provide injectables pretraining. A majority demonstrated increased knowledge after the training. Knowledge required for screening and counseling clients was lower than knowledge on administration. ConclusionPPMVs should be trained before providing injectable services. Additional research is needed on the benefits of job aids for screening and counseling.

Effectiveness of peer detailing in a diarrhea program in Nigeria

Diarrhea causes more than 500,000 deaths of children younger than 5 years, globally, each year. A combination of oral rehydration salts (ORS) and zinc is regarded as the most effective treatment to prevent diarrhea-related deaths among children. We study the effectiveness of a program in Nigeria aimed at increasing usage of ORS and zinc. Peer detailers (educators) reinforce the benefits of the treatment to patent and proprietary medicine vendors (PPMVs), a main source of healthcare in the country. Two aspects of program effectiveness are analyzed: 1) PPMV knowledge that this combination is the most effective treatment and 2) PPMV inventory of ORS and zinc. Hypothesis tests reveal that the percentage of PPMVs with knowledge of the most effective treatment increases significantly in most of the tested Nigerian states after peer detailing. Surprisingly, no significant patterns were detected regarding the percentage of PPMVs with inventory of ORS and zinc. Logistic regression results suggest that PPMVs that were detailed have significantly higher odds ratios for both knowledge and inventory. We discuss our findings regarding the overall effectiveness of the program and the limitations of the study, as well as suggestions for future activities to support information dissemination.

Care-seeking at patent and proprietary medicine vendors in Nigeria.

BackgroundTo achieve health development goals, policymakers are increasingly focused on improving primary care in low- and middle-income countries, and private sector drug retailers offer one channel through which basic services may be delivered. In Nigeria, patent and proprietary medicine vendors (PPMVs) serve as a main source of medications, but little is known about their clientele or how care is sought at PPMVs for common illnesses. We explore differences in care-seeking at PPMV shops based on the most commonly reported symptoms.MethodsIn Kogi and Kwara states, Nigeria, 250 PPMV shop workers and 2,359 customers purchasing drugs were surveyed, and each worker-customer interaction was observed. Multivariate regression analysis was used to assess the association of commonly reported symptoms with care-seeking behavior prior to attending the shop and while interacting with the provider at the shop.ResultsMost customers sought care for headache (30.5 %), fever (22.9 %), cough/cold (18.1 %), or diarrhea (8.4 %). Customers with fever were more likely to report being diagnosed by a formally trained person, to have discussed the illness with and be examined by the shop worker, and have more difficulty paying. In contrast, customers with headache symptoms were less likely to experience these outcomes and spent less money purchasing drugs. Those reporting cough or cold symptoms were less likely to have been diagnosed by a formally trained person, waited longer before visiting the PPMV shop, and were more likely to discuss the illness with the shop worker, but were less likely to be examined or to recommend the purchased drug themselves. If a sick child was brought to the shop, a discussion of the illness and an exam were more likely and more money was spent on drugs.ConclusionsBecause care-seeking behaviors vary by symptoms and the sick person’s age, PPMVs should be trained to treat common illnesses for which customers are unlikely to seek a formal medical consultation. Interventions aimed at improving primary care need to target the places where most people access care, and equip PPMV workers with knowledge and tools to provide basic services.

Management of paediatric illnesses by patent and proprietary medicine vendors in Nigeria.

BackgroundIn Nigeria and elsewhere, informal drug sellers, or patent and proprietary medicine vendors (PPMVs), are a common source of care for children with malaria, diarrhoea, and pneumonia. However, their knowledge and stocking of recommended treatments for these common childhood illnesses are not well understood.MethodsA census of PPMV shops was conducted in Kogi and Kwara states. A shop survey was conducted on a subset of 250 shops. Multivariate regression analysis was used to assess associations between shop worker characteristics and (1) knowledge of optimal treatments for malaria, diarrhoea, and pneumonia, and (2) stocking of essential medicines to treat these illnesses.ResultsFrom the census, 89.9 % of shops stocked oral rehydration solution (ORS), while 61.1 % of shops stocked artemisinin-based combination therapies and 72.2 % of shops stocked amoxicillin. Stocking patterns varied by state, urban/rural location, and according to whether or not the shop was headed by someone with formal health training (e.g. having a professional health education degree). In multivariate analyses, selling drugs wholesale and participating in any training in the past year was associated with a higher likelihood of naming the correct treatment for malaria, and having formal health training was associated with stocking ORS. However, few other PPMV characteristics were predictive of correct knowledge of optimal treatments and stocking behaviour.ConclusionMany PPMVs lack the knowledge and tools to properly treat common childhood illnesses. PPMV knowledge and selling of essential medicines for these illnesses should be strengthened to improve child health in Nigeria.

A Systematic Review of the Role of Proprietary and Patent Medicine Vendors in Healthcare Provision in Nigeria

BackgroundInterventions to reduce the burden of disease and mortality in sub-Saharan Africa increasingly recognize the important role that drug retailers play in delivering basic healthcare services. In Nigeria, owner-operated drug retail outlets, known as patent and proprietary medicine vendors (PPMVs), are a main source of medicines for acute conditions, but their practices are not well understood. Greater understanding of the role of PPMVs and the quality of care they provide is needed in order to inform ongoing national health initiatives that aim to incorporate PPMVs as a delivery mechanism.Objective and MethodsThis paper reviews and synthesizes the existing published and grey literature on the characteristics, knowledge and practices of PPMVs in Nigeria. We searched published and grey literature using a number of electronic databases, supplemented with website searches of relevant international agencies. We included all studies providing outcome data on PPMVs in Nigeria, including non-experimental studies, and assessed the rigor of each study using the WHO-Johns Hopkins Rigor scale. We used narrative synthesis to evaluate the findings.ResultsWe identified 50 articles for inclusion. These studies provided data on a wide range of PPMV outcomes: training; health knowledge; health practices, including drug stocking and dispensing, client interaction, and referral; compliance with regulatory guidelines; and the effects of interventions targeting PPMVs. In general, PPMVs have low health knowledge and poor health treatment practices. However, the literature focuses largely on services for adult malaria, and little is known about other health areas or services for children.ConclusionsThis review highlights several concerns with the quality of the private drug retail sector in Nigeria, as well as gaps in the existing evidence base. Future research should adopt a more holistic view of the services provided by PPMV shops, and evaluate intervention strategies that may improve the services provided in this sector.
