A health technology assessment of COVID-19 vaccination for Nigerian decision-makers: Identifying stakeholders and pathways to support evidence uptake.

BACKGROUND: Nigeria commenced rollout of vaccination for coronavirus disease 2019 (COVID-19) in March 2021 as part of the national public health response to the pandemic. Findings from appropriately contextualized cost-effectiveness analyses (CEA) as part of a wider process involving health technology assessment (HTA) approaches have been important in informing decision-making in this area. In this paper we outline the processes that were followed to identify COVID-19 vaccine stakeholders involved in the selection, approval, funding, procurement and rollout of vaccines in Nigeria, and describe the process routes we identified to support uptake of HTA-related information for evidence-informed policy in Nigeria. METHODS: Our approach to engaging with policy-makers and other stakeholders as part of an HTA of COVID vaccination in Nigeria consisted of three steps, namely: (i) informal discussions with key stakeholders; (ii) stakeholder mapping, analysis and engagement; and (iii) communication and dissemination strategies for the HTA-relevant evidence produced. The analysis of the stakeholder mapping uses the power/interest grid framework. RESULTS: The informal discussion with key stakeholders generated six initial policy questions. Further discussions with policy-makers yielded three suitable policy questions for analysis: which COVID-19 vaccines should be bought; what is the optimal mode of delivery of these vaccines; and what are the cost and cost-effectiveness of vaccinating people highlighted in Nigeria's phase 2 vaccine rollout prioritized by the government, especially the inclusion of those aged between 18 and 49 years. The stakeholder mapping exercise highlighted the range of organizations and groups within Nigeria that could use the information from this HTA to guide decision-making. These stakeholders included both public/government, private and international organizations The dissemination plan developed included disseminating the full HTA results to key stakeholders; production of policy briefs; and presentation at different national and international conferences and peer-reviewed publications. CONCLUSIONS: HTA processes that involve stakeholder engagement will help ensure important policy questions are taken into account when designing any HTA including any underpinning evidence generation. Further guidance about stakeholder engagement throughout HTA is required, especially for those with low interest in vaccine procurement and use.

Antihypertensive medicine use differs between Ghana and Nigeria.

BACKGROUND: Non-communicable diseases are a growing burden in many African countries; cardiovascular disease is the main disease. Antihypertensive medicines (AHM) are a common treatment option but we know little about community use in most low- and medium-income countries (LMIC). We aimed to describe the use of antihypertensive medicines (AHM) in Ghana and Nigeria using a novel data source. METHODS: We used data from mPharma-a health and pharmaceutical company which distributes pharmaceuticals to hospital and retail pharmacies. We extracted data using the anatomical therapeutic chemical (ATC) classification codes and calculated use in defined daily doses and explored patterns by class, medicines, dose, and originator or generic product. RESULTS: AHM use differed between Ghana and Nigeria. The most used classes in Ghana were angiotensin receptor blockers (ARB) followed by calcium channel blockers (CCB) and angiotensin-converting-enzyme inhibitors (ACEi). The five most used products were 16 mg candesartan, 30 mg nifedipine, 10 mg lisinopril, 5 mg amlodipine and 50 mg losartan. In Nigeria ARB, CCB and diuretics were widely used; the top five products were 50 mg losartan, 10 mg lisinopril, 30 mg nifedipine, 40 mg furosemide, and 5 mg amlodipine. More originator products were used in Ghana than Nigeria. CONCLUSION: The differences between Ghana and Nigeria may result from a combination of medical, contextual and policy evidence and reflect factors related to clinical guidance (e.g. standard treatment guidelines), accessibility to prescribers and the role of community pharmacies, and structure of the health system and universal health coverage including funding for medicines. We show the feasibility of using novel data sources to gain insights on medicines use in the community.

Sex differences in the experience of COVID-19 post-traumatic stress symptoms by adults in South Africa.

BACKGROUND: The COVID-19 pandemic has created multiple mental health challenges. Many residents in South Africa face pre-existing elevated levels of stress and the pandemic may have had varying impacts on sub-populations. The aims of this study were to determine: 1) the factors associated with post-traumatic stress symptoms (PTSS) and 2) sex differences in the factors associated with PTSS in adults residing in South Africa during the COVID-19 pandemic. METHODS: Study participants aged 18 years and above, were recruited for this cross-sectional study through an online survey implemented from June 29, 2020 to December 31, 2020. The outcome variable was PTSS; explanatory variables were sex at birth, COVID-19 status, social isolation and access to emotional support. Confounders considered were age, education level completed and current work status. Logistic regressions were used to determine the association between the outcome and explanatory variables after adjusting for confounders. OUTCOMES: There were 489 respondents. Among all respondents, those who were older (AOR: 0.97; 95% CI: 0.95 - 0.99) and had access to emotional support from family and relatives (AOR: 0.27; 95% CI: 0.14 - 0.53) had significantly lower odds of PTSS. Respondents who felt socially isolated had higher odds of PTSS (AOR: 1.17; 95% CI: 1.08 - 1.27). Females had higher PTSS scores and higher odds of PTSS compared to males (AOR: 2.18; 95% CI: 1.41-3.39). Females (AOR: 0.27; 95% CI: 0.08 - 0.95) and males (AOR: 0.26; 95% CI: 0.11, 0.59) who had access to emotional support had significantly lower odds of PTSS than those who had no support. Females (AOR: 1.15; 95% CI: 1.04 -1.27) and males (AOR: 1.19; 95% CI: 0.11, 0.59) who felt socially isolated had higher odds of PTSS compared to those who did not feel socially isolated. INTERPRETATION: Compared to males, females had higher scores and higher odds of reporting PTSS during the COVID-19 pandemic. Access to emotional support ameliorated the odds of having PTSS for both sexes, while feeling socially isolated worsened the odds for both sexes.

Validation of a COVID-19 mental health and wellness survey questionnaire.

BACKGROUND AND AIM: COVID-19 affected mental health and wellbeing. Research is needed to assess its impact using validated tools. The study assessed the content validity, reliability and dimensionality of a multidimensional tool for assessing the mental health and wellbeing of adults. METHODS: An online questionnaire collected data in the second half of 2020 from adults in different countries. The questionnaire included nine sections assessing: COVID-19 experience and sociodemographic profile; health and memory; pandemic stress (pandemic stress index, PSI); financial and lifestyle impact; social support; post-traumatic stress disorder (PTSD); coping strategies; self-care and HIV profile over 57 questions. Content validity was assessed (content validity index, CVI) and participants evaluated the test-retest reliability (Kappa statistic and intra-class correlation coefficient, ICC). Internal consistency of scales was assessed (Cronbach α). The dimensionality of the PSI sections and self-care strategies was assessed by multiple correspondence analysis (MCA) using all responses and SPSS. For qualitative validation, we used a semi-structured interview and NVivo was used for coding and thematic analysis. RESULTS: The overall CVI = 0.83 with lower values for the memory items. Cronbach α for the memory items = 0.94 and ICC = 0.71. Cronbach α for PTSD items was 0.93 and ICC = 0.89. Test-retest scores varied by section. The 2-dimensions solution of MCA for the PSI behavior section explained 33.6% (precautionary measures dimension), 11.4% (response to impact dimension) and overall variance = 45%. The 2-dimensions of the PSI psychosocial impact explained 23.5% (psychosocial impact of the pandemic dimension), 8.3% (psychosocial impact of the precautionary measures of the pandemic dimension) and overall variance = 31.8%. The 2-dimensions of self-care explained 32.9% (dimension of self-care strategies by people who prefer to stay at home and avoid others), 9% (dimension of self-care strategies by outward-going people) and overall variance = 41.9%. Qualitative analysis showed that participants agreed that the multidimensional assessment assessed the effect of the pandemic and that it was better suited to the well-educated. CONCLUSION: The questionnaire has good content validity and can be used to assess the impact of the pandemic in cross-sectional studies especially as individual items. The PSI and self-care strategies need revision to ensure the inclusion of items with strong discrimination.

Feasibility of implementing formal long-distance mentorship for public health physicians: a case study of Association of Public Health Physicians of Nigeria.

BACKGROUND: Conflicting schedules and geographic access limit prospects for mutually beneficial relationships between experts and early career professionals. A formal long-distance mentorship program could address these barriers and potentially bridge the gap of traditional face-to-face mentorship. This study was done to determine the feasibility of implementing a formal long-distance mentorship program amongst public health physicians of Nigeria. METHOD: A mixed-method study comprising of in-depth interviews and surveys was used to collect information from members of the Association of Public Health Physicians in Nigeria. A total of 134 survey participants were recruited consecutively during an annual scientific meeting of the association. In-depth interviewees were purposively selected to ensure diversity in expertise, experience, and social stratifiers such as age. Quantitative data were analyzed using descriptive and inferential statistics, while qualitative data were analyzed using thematic content analysis. RESULTS: Public health physicians of Nigeria are willing to participate in a formal Long-Distance Mentorship Program, and four elements of feasibility were highlighted as necessary for implementing the program. Namely i) capacity to coordinate LDMP, ii) technical expertise and individual competence to provide mentorship, iii) financial capacity to implement and sustain LDMP, and iv) demand for mentorship by mentees. There is a consensus that the organizational structure of the National Postgraduate Medical College of Nigeria and West African College of Physicians provide an enabling environment to initiate a LDMP for public health physicians of Nigeria. The vast human resources with various expertise and the annual National conferences can be leveraged upon to champion and administer the program. However, there is a need for an administrative structure and technical expertise to enable proper coordination. More so, the need for demand creation and the financial requirement was considered gaps that need to be filled to be able to ensure feasibility. Bivariate analysis showed a significant relationship between the dependent variable (preferred role- mentor/mentee) and independent variables (age, year of graduation, and the number of years of practice), while the binary logistic regression model showed that physicians are more likely to participate as mentors with each unit increase in the number of years of practice. This further buttressed the need to commence the mentoring process as soon as trainees gain entrance into the program, as mentorship does not just prepare them for excellent public health practice, but also builds their capacity to mentor the younger and upcoming public health physicians. CONCLUSION: There are enabling structures to incorporate a formal long-distance mentorship program for public health physicians in Nigeria, and physicians are willing to participate in such a program. However, the feasibility of establishing a successful and sustainable program will require robust coordination, technical expertise, demand creation, and financial commitment at both institutional and college levels.

Health technology assessment and priority setting for universal health coverage: a qualitative study of stakeholders' capacity, needs, policy areas of demand and perspectives in Nigeria.

INTRODUCTION: Health technology assessment (HTA) is an effective tool to support priority setting and generate evidence for decision making especially en route to achieving universal health coverage (UHC). We assessed the capacity needs, policy areas of demand, and perspectives of key stakeholders for evidence-informed decision making in Nigeria where HTA is still new. METHODS: We surveyed 31 participants including decision makers, policy makers, academic researchers, civil society organizations, community-based organizations, development partners, health professional organizations. We revised an existing survey to qualitatively examine the need, policy areas of demand, and perspectives of stakeholders on HTA. We then analyzed responses and explored key themes. RESULTS: Most respondents were associated with organizations that generated or facilitated health services research. Research institutes highlighted their ability to provide expertise and skills for HTA research but some respondents noted a lack of human capacity for HTA. HTA was considered an important and valuable priority-setting tool with a key role in the design of health benefits packages, clinical guideline development, and service improvement. Public health programs, medicines and vaccines were the three main technology types that would especially benefit from the application of HTA. The perceived availability and accessibility of suitable local data to support HTA varied widely but was mostly considered inadequate and limited. Respondents needed evidence on health system financing, health service provision, burden of disease and noted a need for training support in research methodology, HTA and data management. CONCLUSION: The use of HTA by policymakers and communities in Nigeria is very limited mainly due to inadequate and insufficient capacity to produce and use HTA. Developing sustainable and institutionalized HTA systems requires in-country expertise and active participation from a range of stakeholders. Stakeholder participation in identifying HTA topics and conducting relevant research will enhance the use of HTA evidence produced for decision making. Therefore, the identified training needs for HTA and possible research topics should be considered a priority in establishing HTA for evidence-informed policy making for achieving UHC particularly among the most vulnerable people in Nigeria.

Policy dialogue to support maternal newborn child health evidence use in policymaking: The lessons learnt from the Nigeria research days first edition.

The use of evidence in decision-making and practice can be improved through diverse interventions, including policy dialogue. The Department of Family Health, Federal Ministry of Health of Nigeria initiated and organized the Nigeria Research Days (NRD), to serve as a platform for exchange between researchers and policymakers for improving maternal, new-born and child health. The study reports on the conceptualization, organization and lessons learned from the first edition. A cross-sectional study was designed to assess the effectiveness of a policy dialogue during the NRDs. Data were collected from the feasibility and workshop evaluation surveys. A descriptive analysis of data was performed. As a result, the Nigeria Research Days meets all the criteria for a successful policy dialogue. The participants positively rated the content and format of the meeting and made suggestions for improvement. They were willing to implement the recommendations of the final communiqué. The lessons learned from this first edition will be used to improve future editions.

Analysing key influences over actors' use of evidence in developing policies and strategies in Nigeria: a retrospective study of the Integrated Maternal Newborn and Child Health strategy.

BACKGROUND: Evidence-informed policymaking has been promoted as a means of ensuring better outcomes. However, what counts as evidence in policymaking lies within a spectrum of expert knowledge and scientifically generated information. Since not all forms of evidence share an equal validity or weighting for policymakers, it is important to understand the key factors that influence their preferences for different types of evidence in policy and strategy development. METHOD: A retrospective study was carried out at the national level in Nigeria using a case-study approach to examine the Nigerian Integrated Maternal Newborn and Child Health (IMNCH) strategy. Two frameworks were used for conceptualization and data analysis, namely (1) to analyse the role of evidence in policymaking and (2) the policy triangle. They were used to explore the key contextual and participatory influences on choice of evidence in developing the IMNCH strategy. Data was collected through review of relevant national documents and in-depth interviews of purposively selected key policy and strategic decision makers. Thematic analysis was applied to generate information from collected data. RESULTS: The breadth of evidence used was wide, ranging from expert opinions to systematic reviews. The choice of different types of evidence was found to overlap across actor categories. Key influences over actors' choice of evidence were: (1) perceived robustness of evidence - comprehensive, representative, recent, scientifically sound; (2) roles in evidence process, i.e. their degree and level of participation in evidence generation and dissemination, with regards to their role in the policy process; and (3) contextual factors such as global agenda and influence, timeline for strategy development, availability of resources for evidence generation, and lessons learnt from previous unsuccessful policies/plans. CONCLUSION: Actors' preferences for different types of evidence for policy are influenced not only by the characteristics of evidence itself, but on actors' roles in the evidence process, their power to influence the policy, and the context in which evidence is used.

How do health workers perceive and practice monitoring and evaluation of malaria control interventions in South-east Nigeria?

BACKGROUND: The Anambra state Malaria Control Booster Project (ANMCBP) depends on an effective monitoring and evaluation (M&E) system to continuously improve the implementation of the malaria control interventions. However, it is not clear how the health workers that are expected to be the fulcrum of the malaria M&E perceive and practise M&E. The study was carried out to determine the knowledge, perception, and practice of Malaria M&E among selected health staff, and to identify related socio-demographic factors, including cadre of staff. METHODS: A semi-structured questionnaire and an observation checklist were used to collect information from selected health workers in public primary health centres in all 21 local government areas of the State. Multistage sampling technique was used in selection of respondents. The questionnaire explored knowledge, perception and practice of malaria M&E from 213 health workers. The observation checklist was used to record the actual practice of malaria M&E as observed by trained supervisors. RESULTS: Over 80% of health workers interviewed were able to correctly identify the malaria M&E forms; 25.4% knew the basis for categorizing Artemisinin-based combination therapy (ACT) into ACT1 - ACT4; 97.6% of the respondents felt there was need to keep proper records to have information available and 7.5% of them kept records because they were asked to do so. Over 90% of respondents reported correct practice of M&E, but on verification of actual practice, 55.6% of the respondents had at least one wrongly filled form, and half of these had none of their forms properly filled; about 68.4% of respondents had met specified timeline for data transmission. Differences observed in knowledge, perception and practice of M&E across age categories and cadres were only significant in ability to identify malaria M&E forms; diagnosis of malaria based on blood film microscopy result; perception of how age should be recorded; and reported practice of keeping data till they are requested. Among lower cadre of staff, gaps still exist in knowledge, perception and practice of malaria M&E. CONCLUSIONS: Gaps still exist in health workers' understanding of malaria data management, perception of efficient data transmission and observed practice of malaria M&E.

What, how and who: Cost-effectiveness analyses of COVID-19 vaccination to inform key policies in Nigeria.

While safe and efficacious COVID-19 vaccines have achieved high coverage in high-income settings, roll-out remains slow in sub-Saharan Africa. By April 2022, Nigeria, a country of over 200 million people, had only distributed 34 million doses. To ensure the optimal use of health resources, cost-effectiveness analyses can inform key policy questions in the health technology assessment process. We carried out several cost-effectiveness analyses exploring different COVID-19 vaccination scenarios in Nigeria. In consultation with Nigerian stakeholders, we addressed three key questions: what vaccines to buy, how to deliver them and what age groups to target. We combined an epidemiological model of virus transmission parameterised with Nigeria specific data with a costing model that incorporated local resource use assumptions and prices, both for vaccine delivery as well as costs associated with care and treatment of COVID-19. Scenarios of vaccination were compared with no vaccination. Incremental cost-effectiveness ratios were estimated in terms of costs per disability-adjusted life years averted and compared to commonly used cost-effectiveness ratios. Viral vector vaccines are cost-effective (or cost saving), particularly when targeting older adults. Despite higher efficacy, vaccines employing mRNA technologies are less cost-effective due to high current dose prices. The method of delivery of vaccines makes little difference to the cost-effectiveness of the vaccine. COVID-19 vaccines can be highly effective and cost-effective (as well as cost-saving), although an important determinant of the latter is the price per dose and the age groups prioritised for vaccination. From a health system perspective, viral vector vaccines may represent most cost-effective choices for Nigeria, although this may change with price negotiation.

Increasing access to modern contraceptives: the potential role of community solidarity through altruistic contributions.

BACKGROUND: There is an urgent need for universal access to modern contraceptives in Nigeria, to facilitate the achievement of the Millennium Development Goals and other national goals. This study provides information on the potential role of community solidarity in increasing access to contraceptives for the most-poor people through exploration of the role of altruism by determining level of altruistic willingness to pay (WTP) for modern contraceptives across different geographic contexts in Nigeria. METHODS: It was a cross-sectional national survey which took place in six states spread across the six-geopolitical zones of the country. In each state, an urban and a rural area were selected for the study, giving a total of 6 urban and 6 rural sites. A pre-tested interviewer-administered questionnaire was used to collect information from at least 720 randomly selected householders from each state. The targeted respondent in a household was a female primary care giver of child bearing age (usually the wives), or in her absence, another female household member of child bearing age. A scenario on altruistic WTP was presented before the value was elicited using a binary with open-ended follow-up question format. Test of validity of elicited altruistic WTP was undertaken using Tobit regression. FINDINGS: More than 50 % of the respondents across all the states were willing to contribute some money so that the very poor would be provided with modern contraceptives. The average amount of money that people were willing to contribute annually was 650 Naira (US$4.5). Mean altruistic WTP differed across SES quintiles and urban-rural divide (p < .01). Multiple regression analysis showed that age was negatively related to altruistic WTP (p < 0.05). However, years of schooling, being employed by government or being a big business person, prior experience of paying for contraceptives and socioeconomic status had statistically significant effects on altruistic WTP (p < 0.05). CONCLUSION: There is room for community solidarity to ensure that the very poor benefit from modern contraceptives and assure universal coverage with modern contraceptives. The factors that determine altruistic WTP should be harnessed to ensure that altruistic contributions are actually made. The challenge will be how to collect and pool the altruistic contributions for purchasing and delivering modern contraceptives to the most-poor, within the context of community financing.

Examining equity in access to long-lasting insecticide nets and artemisinin-based combination therapy in Anambra State, Nigeria.

BACKGROUND: In order to achieve universal health coverage, the government of Anambra State, southeast Nigeria has distributed free Long-lasting Insecticide treated Nets (LLINs) to the general population and delivered free Artemisinin-based Combination Therapy (ACT) to pregnant women and children less than 5 years. However, the levels of coverage with LLINS and ACTs is not clear, especially coverage of different socio-economic status (SES) population groups. This study was carried out to determine the level of coverage and access to LLINs and ACTs amongst different SES groups. METHODS: A questionnaire was used to collect data from randomly selected households in 19 local government areas of the State. Selected households had a pregnant woman and/or a child less than 5 years. The lot quality assurance sampling (LQAS) methodology was used in sampling. The questionnaire explored the availability and utilization of LLINs and ACTs from 2394 households. An asset-based SES index was used to examine the level of access of LLINS and ACTs to different SES quintiles. RESULTS: It was found that 80.5% of the households had an LLIN and 64.4% of the households stated that they actually used the nets the previous night. The findings showed that 42.3% of pregnant women who had fever within the past month received ACTs, while 37.5% of children<5 years old who had malaria in the past month had received ACTs. There was equity in ownership of nets for the range 1-5 nets per household. No significant SES difference was found in use of ACTs for treatment of malaria in children under five years old and in pregnant women. CONCLUSIONS: The free distribution of LLINs and ACTs increased household coverage of both malaria control interventions and bridged the equity gap in access to them among the most vulnerable groups.

Factors Associated With Coverage of Health Insurance Among Women in Malawi.

Introduction: Access to healthcare for the vulnerable groups including women has long been a theme encouraged worldwide from the first general assembly on health to the current sustainable development goals. Despite many countries having a free public healthcare system, there are inequalities in access to care and significant out-of-pocket spending, pushing most women into poverty against the principles of universal health coverage. Coverage of Malawian women with health insurance is poor; thus, there is limited cushioning and high risk of poverty, as women bear costs of care as primary caregivers. There is need to explore determinants of coverage of health insurance among women in Malawi to inform health policy. Methodology: This study was quantitative in nature, using cross-sectional secondary data from the 2015 to 2016 Malawi Demographic and Health Survey involving women aged between 15 and 49 years. We assessed factors associated with insurance coverage by comparing women with and without insurance schemes using binary logistic regression. Analysis was done using STATA statistical package version 13. Results: The analysis included a total of 24,562 women with a mean age of 28 SD (9.3). Of these cases, 1.5% had health insurance. High education attainment, occupation, and wealth were significantly associated with health insurance ownership, with all having p-values of < 0.01. On the other hand, a woman's residence, marital status, and who heads a household were not associated with ownership of health insurance significantly. Conclusion: Education, occupation, and wealth have a key role in influencing a woman's choice in owning health insurance. This informs policymakers and health insurance providers on how best to approach women's health financing and factors to target in social security programs and health insurance products that speak to women's needs and capacity.

Treatment of uncomplicated malaria at public health facilities and medicine retailers in south-eastern Nigeria.

BACKGROUND: At primary care facilities in Nigeria, national treatment guidelines state that malaria should be symptomatically diagnosed and treated with artemisinin-based combination therapy (ACT). Evidence from households and health care providers indicates that many patients do not receive the recommended treatment. This study sought to determine the extent of the problem by collecting data as patients and caregivers leave health facilities, and determine what influences the treatment received. METHODS: A cross-sectional cluster survey of 2,039 respondents exiting public health centres, pharmacies and patent medicine dealers was undertaken in urban and rural settings in Enugu State, south-eastern Nigeria. RESULTS: Although 79% of febrile patients received an anti-malarial, only 23% received an ACT. Many patients (38%) received sulphadoxine-pyrimethamine (SP). A further 13% of patients received an artemisinin-derivative as a monotherapy. An estimated 66% of ACT dispensed was in the correct dose. The odds of a patient receiving an ACT was highly associated with consumer demand (OR: 55.5, p < 0.001). CONCLUSION: Few febrile patients attending public health facilities, pharmacies and patent medicine dealers received an ACT, and the use of artemisinin-monotherapy and less effective anti-malarials is concerning. The results emphasize the importance of addressing both demand and supply-side influences on malaria treatment and the need for interventions that target consumer preferences as well as seek to improve health service provision.

Examining appropriate diagnosis and treatment of malaria: availability and use of rapid diagnostic tests and artemisinin-based combination therapy in public and private health facilities in south east Nigeria.

BACKGROUND: Rapid diagnostic tests (RDTs) and Artemisinin-based combination therapy (ACT) have been widely advocated by government and the international community as cost-effective tools for diagnosis and treatment of malaria. ACTs are now the first line treatment drug for malaria in Nigeria and RDTs have been introduced by the government to bridge the existing gaps in proper diagnosis. However, it is not known how readily available these RDTs and ACTs are in public and private health facilities and whether health workers are actually using them. Hence, this study investigated the levels of availability and use of RDTs and ACTs in these facilities. METHODS: The study was undertaken in Enugu state, southeast Nigeria in March 2009. Data was collected from heads of 74 public and private health facilities on the availability and use of RDTs and ACTs. Also, the availability of RDTs and the types of ACTs that were available in the facilities were documented. RESULTS: Only 31.1% of the health facilities used RDTs to diagnose malaria. The majority used the syndromic approach. However, 61.1% of healthcare providers were aware of RDTs. RDTs were available in 53.3% of the facilities. Public health facilities and health facilities in the urban areas were using RDTs more and these were mainly bought from pharmacy shops and supplied by NGOs. The main reasons given for non use are unreliability of RDTs, supply issues, costs, preference for other methods of diagnosis and providers' ignorance. ACTs were the drug of choice for most public health facilities and the drugs were readily available in these facilities. CONCLUSION: Although many providers were knowledgeable about RDTs, not many facilities used it. ACTS were readily available and used in public but not private health facilities. However, the reported use of ACTs with limited proper diagnosis implies that there could be high incidence of inappropriate case management of malaria which can also increase the economic burden of illnesses. Government and donors should ensure constant availability of RDTs in both public and private facilities, so that every treatment with ACTs is accompanied with proper diagnosis.

Investigating determinants of out-of-pocket spending and strategies for coping with payments for healthcare in southeast Nigeria.

BACKGROUND: Out-of-pocket spending (OOPS) is the major payment strategy for healthcare in Nigeria. Hence, the paper assessed the determinants socio-economic status (SES) of OOPS and strategies for coping with payments for healthcare in urban, semi-urban and rural areas of southeast Nigeria. This paper provides information that would be required to improve financial accessibility and equity in financing within the public health care system. METHODS: The study areas were three rural and three urban areas from Ebonyi and Enugu states in South-east Nigeria. Cross-sectional survey using interviewer-administered questionnaires to randomly selected householders was the study tool. A socio-economic status (SES) index that was developed using principal components analysis was used to examine levels of inequity in OOPS and regression analysis was used to examine the determinants of use of OOPS. RESULTS: All the SES groups equally sought healthcare when they needed to. However, the poorest households were most likely to use low level and informal providers such as traditional healers, whilst the least poor households were more likely to use the services of higher level and formal providers such as health centres and hospitals. The better-off SES more than worse-off SES groups used OOPS to pay for healthcare. The use of own money was the commonest payment-coping mechanism in the three communities. The sales of movable household assets or land were not commonly used as payment-coping mechanisms. Decreasing SES was associated with increased sale of household assets to cope with payment for healthcare in one of the communities. Fee exemptions and subsidies were almost non-existent as coping mechanisms in this study CONCLUSIONS: There is the need to reduce OOPS and channel and improve equity in healthcare financing by designing and implementing payment strategies that will assure financial risk protection of the poor such pre-payment mechanisms with government paying for the poor.

Predictors of current tobacco smoking by adolescents in Nigeria: Interaction between school location and socioeconomic status.

INTRODUCTION: Tobacco smoking is the largest preventable cause of global mortality, with its prevalence increasing in Sub-Saharan Africa, particularly among adolescents. We sought to determine the factors associated with tobacco smoking among Nigerian school adolescents and investigate the interaction between school location and socioeconomic status (SES). METHODS: Using a cross-sectional study design, 4332 eighth to tenth grade students in rural and urban secondary schools in Enugu State, Nigeria, were selected by stratified two-stage cluster sampling. We collected data using a modified Global Youth Tobacco Survey (GYTS) Core Questionnaire. Outcome measures were current smoking of cigarettes and other smoked tobacco. Multilevel mixed effects logistic regression models were used to determine factors associated with current tobacco smoking and were considered statistically significant at p<0.05. RESULTS: Prevalences of current smoking of cigarettes and other smoked tobacco were 13.3% (95% CI: 11.3-15.7) and 5.8% (95% CI: 4.6-7.2), respectively. Possession of higher weekly allowance, exposure to secondhand smoke or tobacco advertisements, having smoking parents, friends or classmates who smoke, and sale of cigarettes near school, were positively associated with current smoking of tobacco. Female sex, having both parents employed and being exposed to tobacco teaching in school were negatively associated with current cigarette smoking while increasing age and high father's SES were negatively associated with current smoking of other tobacco products. There was an interaction between school location and father's SES in the association with cigarette smoking. The higher odds of smoking in rural versus urban schools were much higher for students with fathers of high SES compared to low SES. In rural schools, high SES was associated with higher odds of smoking, but in urban schools low SES was associated with higher odds of smoking. CONCLUSIONS Environmental factors are associated with adolescent tobacco smoking. Tobacco control programs should use targeted strategies that vary depending on the local context.

Improving childhood malaria treatment and referral practices by training patent medicine vendors in rural south-east Nigeria.

BACKGROUND: Malaria remains a major cause of morbidity and mortality among children under five years of age in Nigeria. Most of the early treatments for fever and malaria occur through self-medication with anti-malarials bought over-the-counter (OTC) from untrained drug vendors. Self-medication through drug vendors can be ineffective, with increased risks of drug toxicity and development of drug resistance. Global malaria control initiatives highlights the potential role of drug vendors to improve access to early effective malaria treatment, which underscores the need for interventions to improve treatment obtained from these outlets. This study aimed to determine the feasibility and impact of training rural drug vendors on community-based malaria treatment and advice with referral of severe cases to a health facility. METHODS: A drug vendor-training programme was carried out between 2003 and 2005 in Ugwuogo-Nike, a rural community in south-east Nigeria. A total of 16 drug vendors were trained and monitored for eight months. The programme was evaluated to measure changes in drug vendor practice and knowledge using exit interviews. In addition, home visits were conducted to measure compliance with referral. RESULTS: The intervention achieved major improvements in drug selling and referral practices and knowledge. Exit interviews confirmed significant increases in appropriate anti-malarial drug dispensing, correct history questions asked and advice given. Improvements in malaria knowledge was established and 80% compliance with referred cases was observed during the study period, CONCLUSION: The remarkable change in knowledge and practices observed indicates that training of drug vendors, as a means of communication in the community, is feasible and strongly supports their inclusion in control strategies aimed at improving prompt effective treatment of malaria with referral of severe cases.

Cost-effectiveness analysis of rapid diagnostic test, microscopy and syndromic approach in the diagnosis of malaria in Nigeria: implications for scaling-up deployment of ACT.

BACKGROUND: The diagnosis and treatment of malaria is often based on syndromic presentation (presumptive treatment) and microscopic examination of blood films. Treatment based on syndromic approach has been found to be costly, and contributes to the development of drug resistance, while microscopic diagnosis of malaria is time-consuming and labour-intensive. Also, there is lack of trained microscopists and reliable equipment especially in rural areas of Nigeria. However, although rapid diagnostic tests (RDTs) have improved the ease of appropriate diagnosis of malaria diagnosis, the cost-effectiveness of RDTs in case management of malaria has not been evaluated in Nigeria. The study hence compares the cost-effectiveness of RDT versus syndromic diagnosis and microscopy. METHODS: A total of 638 patients with fever, clinically diagnosed as malaria (presumptive malaria) by health workers, were selected for examination with both RDT and microscopy. Patients positive on RDT received artemisinin-based combination therapy (ACT) and febrile patients negative on RDT received an antibiotic treatment. Using a decision tree model for a hypothetical cohort of 100,000 patients, the diagnostic alternatives considered were presumptive treatment (base strategy), RDT and microscopy. Costs were based on a consumer and provider perspective while the outcome measure was deaths averted. Information on costs and malaria epidemiology were locally generated, and along with available data on effectiveness of diagnostic tests, adherence level to drugs for treatment, and drug efficacy levels, cost-effectiveness estimates were computed using TreeAge programme. Results were reported based on costs and effects per strategy, and incremental cost-effectiveness ratios. RESULTS: The cost-effectiveness analysis at 43.1% prevalence level showed an incremental cost effectiveness ratio (ICER) of 221 per deaths averted between RDT and presumptive treatment, while microscopy is dominated at that level. There was also a lesser cost of RDT ($0.34 million) compared to presumptive treatment ($0.37 million) and microscopy ($0.39 million), with effectiveness values of 99,862, 99,735 and 99,851 for RDT, presumptive treatment and microscopy, respectively. Cost-effectiveness was affected by malaria prevalence level, ACT adherence level, cost of ACT, proportion of non-malaria febrile illness cases that were bacterial, and microscopy and RDT sensitivity. CONCLUSION: RDT is cost-effective when compared to other diagnostic strategies for malaria treatment at malaria prevalence of 43.1% and, therefore, a very good strategy for diagnosis of malaria in Nigeria. There is opportunity for cost savings if rapid diagnostic tests are introduced in health facilities in Nigeria for case management of malaria.

Perception and practice of breastfeeding among HIV positive mothers receiving care for prevention of mother to child transmission in South-East, Nigeria.

BACKGROUND: Although the risk of HIV transmission through breastfeeding is reduced considerably with the use of antiretroviral therapy, infant feeding by HIV positive mothers remains controversial. Weighing risks against benefits generates intense debate among policymakers, program managers and service providers in sub-Saharan Africa, considering that the major causes of infant death of malnutrition and infectious diseases, could be prevented if mothers breastfeed their babies. Whereas breastfeeding involves some risk of HIV transmission, not breastfeeding poses considerable risk to infant survival. This study investigated perceptions and practice of breastfeeding of HIV-exposed infants among HIV positive mothers. METHODS: A cross-sectional descriptive study was conducted in Enugu metropolis among HIV positive mothers receiving care for prevention of mother-to-child transmission of HIV from two public and two private hospitals. Interviewer-administered questionnaire survey was done with 550 participants as they exited the final point of service delivery. Descriptive statistics of perception and practice variables and cross tabulation of selected variables was performed. RESULTS: Most mothers knew that HIV could be transmitted through breast milk. The majority perceived any type of breastfeeding as beneficial to the infant: 230 (83.6%) in private facilities, and 188 (68.4%) public facilities. Over three-quarters of the mothers breastfed their infants and their reasons for breastfeeding included personal choice, cultural norms, fear of HIV status being disclosed and pressure from family members. A statistical significant association was found between; (i) practice of breastfeeding and marital status, (p < 0.01), and (ii) practice of breastfeeding and household income provider (p = 0.02). However, neither marital status (AOR 1.4; 95% CI 0.3, 6.8) nor being the household income provider (AOR 4.9; 95% CI 0.6, 12.9) is a significant predictor of breastfeeding of HIV-exposed infants. CONCLUSIONS: Breastfeeding remains a common trend among HIV positive women and it is associated with economic independence of women and social support. Fear of stigma negatively affects practice of breastfeeding. Hence, HIV positive mothers need economic independence and the support of family members to practice recommended infant feeding options.
