Stated and actual altruistic willingness to pay for insecticide-treated nets in Nigeria: validity of open-ended and binary with follow-up questions.

OBJECTIVES: To determine whether the binary with follow-up (BWFU) or open-ended (OPED) contingent valuation question format would yield better valid estimates of altruistic willingness to pay (WTP) and examine the feasibility of using intra-community altruistic contributions to procure insecticide-treated nets (ITNs) for the poor in Nigeria. METHODS: Structured questionnaires were used to elicit stated altruistic WTP from a random sub-sample of respondents that had either the OPED or BWFU used to elicit WTP in Southeast Nigeria. One month after the survey the respondents were asked to redeem their WTP pledges. Construct validity was determined using econometric analyses, while phi correlation coefficient was used to determine criterion validity. FINDINGS: More than 57% of the respondents were hypothetically willing to pay for altruism in both BWFU and OPED groups. Altruistic WTP was positively related to respondents' WTP for own nets (p<0.01) and nets for other household members (p<0.05) in both groups. A total of 27.0% and 33.1% of the respondents with positive hypothetical WTP in the BWFU and OPED actually contributed. Phi correlation coefficient was 0.23 (95%CI 0.20-0.29) in BWFU and 0.49 (95%CI 0.44-0.54) in OPED. The money realised was used to buy some ITNs, which were presented to poor people selected by community leaders. CONCLUSION: The OPED elicited better valid estimates of altruistic WTP than BWFU. The potential for more capable people to contribute for the poor in ITNs programmes actually exist and malaria control programmes should explore altruistic contributions as a means to increase net coverage

Exemption policies and community preferences for tropical endemic diseases in the Bamako initiative programme in Nigeria.

We determined the actual written policies/guidelines and practices of fee exemptions aimed at the primary health-care level for tropical diseases treatment within the Bamako initiative system and the community's and decision makers' preferences for exemption in Nigeria. Health policy documents from the federal and state ministries of health were reviewed to determine the guidelines for exemptions, services, goods and category of people to receive exemptions. The records of the local government areas, health centres and community health committees were also reviewed to check who had received exemptions and modalities for doing so. In addition, household surveys using questionnaires was conducted. There is no clear-cut national policy regarding exemption. In areas where exemption exists, these are largely unofficial, as no official documents exist to support exemption. A total of 1594 individuals were surveyed. Community members prefer pregnant women, children and patients with TB, malaria, onchocerciasis and leprosy to be exempted from payment of fees: decision makers prefer the poor, children and patients with malaria, TB and leprosy to be exempted from payment for drugs, registration, consultation and preventive services such as immunization and antenatal services. One area of divergence between the preferences of the community and decision makers is the issue of exempting people with malaria and HIV/AIDS

Examining inequities in incidence of catastrophic health expenditures on different healthcare services and health facilities in Nigeria.

OBJECTIVE: There is limited evidence about levels of socio-economic and other differences in catastrophic health spending in Nigeria and in many sub-Saharan African countries. The study estimated the level of catastrophic healthcare expenditures for different healthcare services and facilities and their distribution across socioeconomic status (SES) groups. METHODS: The study took place in four Local Government Areas in southeast Nigeria. Data were collected using interviewer-administered questionnaires administered to 4873 households. Catastrophic health expenditures (CHE) were measured using a threshold of 40% of monthly non-food expenditure. We examined both total monthly health expenditure and disaggregated expenditure by source and type of care. RESULTS: The average total household health expenditure per month was 2354 Naira ($19.6). For outpatient services, average monthly expenditure was 1809 Naira ($15.1), whilst for inpatient services it was 610 Naira ($5.1). Higher health expenditures were incurred by urban residents and the better-off SES groups. Overall, 27% of households incurred CHE, higher for poorer socioeconomic groups and for rural residents. Only 1.0% of households had a member that was enrolled in a health insurance scheme. CONCLUSION: The worse-off households (the poorest SES and rural dwellers) experienced the highest burden of health expenditure. There was almost a complete lack of financial risk protection. Health reform mechanisms are needed to ensure universal coverage with financial risk protection mechanisms

Valuing the benefits of a health intervention using three different approaches to contingent valuation: re-treatment of mosquito bed-nets in Nigeria.

OBJECTIVES: To determine the level of willingness to pay (WTP) for re-treatment of mosquito nets and to compare the theoretical validity of WTP estimates from three contingent valuation question formats: the bidding game, binary with follow-up technique, and a novel structured haggling technique that mimicked price-taking behaviour in the study area. METHODS: WTP was elicited from randomly selected respondents from three villages in Southeast Nigeria, using pretested interviewer-administered questionnaires. Respondents' WTP for insecticide-treated nets (ITNs) was first elicited before their WTP for re-treatment of ITNs. Ordinary least-squares regression was used to assess theoretical validity. RESULTS: More than 95% of the respondents were willing to pay for re-treatment. The mean WTP was 37.1 Naira, 43.4 Naira and 49.2 Naira in the bidding game, binary with follow-up and structured haggling groups, respectively (US dollar 1.00 = 120 Naira). The WTP estimates elicited across the three question formats were statistically different (P < 0.01). Ordinary least-squares estimation showed that WTP was positively related to many variables, especially stated WTP for ITNs (P < 0.05). Structured haggling generated the highest number of statistically significant variables to explain WTP. CONCLUSIONS: The three contingent valuation approaches generated different distributions of WTP for net retreatment, possibly due to their inherent differences. Structured haggling generated the most theoretically valid estimates of WTP. The levels of WTP identified suggest that user fees exceeding 50 Naira per net re-treatment may discourage demand for the service. This is an important challenge for ITN programmes

Can Strategic Health Purchasing Reduce Inefficiency and Corruption in the Health Sector? The Case of Nigeria

Despite limited government budgets for health in many sub-Saharan African countries, some countries have improved health outcomes at low cost by being strategic in allocating and spending available resources. Strategic health purchasing is receiving increasing attention as a way to improve health system performance within financial constraints. Health purchasing, one of the health financing functions of health systems, is the transfer of pooled funds to health providers to deliver covered services. Strategic health purchasing uses evidence and information about population health needs and health provider performance to make decisions about which health services should have priority for public funding, which providers will provide these services, and how and how much providers will be paid to deliver those services. Strategic purchasing has enabled some countries to make progress on health sector goals while improving efficiency, equity, transparency, and accountability. However, when countries have high levels of corruption and low levels of accountability, as in Nigeria, strategic purchasing may be less effective and more money for health may not yield the expected public health benefits. This commentary uses the Strategic Health Purchasing Progress Tracking Framework developed by the Strategic Purchasing Africa Resource Center (SPARC) and its technical partners to examine health purchasing functions in Nigeria’s main health financing schemes, how corruption affects the effectiveness of health purchasing in Nigeria, and opportunities to use strategic purchasing as a tool to address corruption in health financing by improving the transparency and accountability of health resource allocation and use.</p

Do malaria preventive interventions reach the poor? Socioeconomic inequities in expenditure on and use of mosquito control tools in Sudan.

OBJECTIVES: To determine levels of socioeconomic inequities in the prevention of malaria, and to examine the implications of the findings for improving the equitable control of malaria in the Sudan. METHODS: A cross-sectional survey using a pre-tested interviewer-administered questionnaire was administered to 720 randomly selected householders from six localities in Gezira and Khartoum States. A socioeconomic status (SES) index, which was developed using principal components analysis, was used to examine socioeconomic inequity in the prevention of malaria. FINDINGS: Socioeconomic status was positively related to expenditures and use of vector control tools. The poorest households spent the least amounts of money to prevent malaria and were the least likely to own mosquito nets. CONCLUSION: The inequity in the prevention of malaria in the study areas has to be redressed before malaria can be effectively controlled in Sudan. Malaria control managers should continually determine the extent to which malaria preventive tools reach the poorest socioeconomic groups, and fashion strategies that will ensure that equity is always maintained

Are malaria treatment expenditures catastrophic to different socio-economic and geographic groups and how do they cope with payment? A study in southeast Nigeria.

OBJECTIVES: To determine the inequities in the household income depletion resulting from malaria treatment expenditures, the sacrifice of basic household needs (catastrophe) and the differences in payment strategies among different socio-economic and geographic groups in southeast Nigeria. METHODS: Data were gathered through pre-tested, structured questionnaires from a random sample of 2 250 householders in rural and urban parts of southeast Nigeria. The level of catastrophic malaria treatment expenditure was computed as the percentage of average monthly malaria treatment expenditure divided by the average monthly non-food household expenditure, using a threshold of 5%. Socio-economic inequity was established using a socio-economic status (SES) index, while a rural-urban comparison examined geographic disparities. RESULTS: The average cost to treat a case of malaria was 796.5 Naira ($6.64) for adults and 789.0 Naira ($6.58) for children. The monthly malaria treatment expenditure as a proportion of monthly household non-food expenditure was 7.8%, 8.5%, 5.5% and 3.9% for the most poor, very poor, poor and least poor SES groups respectively. Malaria treatment accounted for 7.1% and 5.0% of non-food expenditures for rural and urban dwellers, respectively. More than 95% of the people financed their treatment through out-of-pocket payment (OOP), with no SES and rural-urban variance, as opposed to insurance payment mechanisms and fee exemptions. CONCLUSION: There were socio-economic and geographic inequities in the financial burden resulting from malaria treatment. The treatment expenditure depleted more of the aggregate income of the two worse-off SES (Q1 and Q2) and of the rural dwellers. Government and donor agencies should institute the abolition of user fees for malaria, the transition from OOP to pre-payment mechanisms and the improvement of physical access to appropriate malaria treatment services, as well as subsidies and deferrals in order to engender financial risk protection from malaria treatment

Willingness to pay for community-based health insurance in Nigeria: do economic status and place of residence matter?

OBJECTIVE: We examine socio-economic status (SES) and geographic differences in willingness of respondents to pay for community-based health insurance (CBHI). METHODS: The study took place in Anambra and Enugu states, south-east Nigeria. It involved a rural, an urban and a semi-urban community in each of the two states. A pre-tested interviewer-administered questionnaire was used to collect information from a total of 3070 households selected by simple random sampling. Contingent valuation was used to elicit willingness to pay (WTP) using the bidding game format. Data were examined for correlation between SES and geographic locations with WTP. Log ordinary least squares (OLS) was used to examine the construct validity of elicited WTP. RESULTS: Generally, less than 40% of the respondents were willing to pay for CBHI membership for themselves or other household members. The proportions of people who were willing to pay were much lower in the rural communities, at less than 7%. The average that respondents were willing to pay as a monthly premium for themselves ranged from 250 Naira (US$1.7) in a rural community to 343 Naira (US$2.9) in an urban community. The higher the SES group, the higher the stated WTP amount. Similarly, the urbanites stated higher WTP compared with peri-urban and rural dwellers. Males and people with more education stated higher WTP values than females and those with less education. Log OLS also showed that previously paying out-of-pocket for health care was negatively related to WTP. Previously paying for health care using any health insurance mechanism was positively related to WTP. CONCLUSION: Economic status and place of residence amongst other factors matter in peoples' WTP for CBHI membership. Consumer awareness has to be created about the benefits of CBHI, especially in rural areas, and the amount to be paid has to be augmented with other means of financing (e.g. government and/or donor subsidies) to ensure success and sustainability of CBHI schemes

Increasing coverage of insecticide-treated nets in rural Nigeria: implications of consumer knowledge, preferences and expenditures for malaria prevention

BACKGROUND: The coverage of insecticide-treated nets (ITNs) remains low despite existing distribution strategies, hence, it was important to assess consumers' preferences for distribution of ITNs, as well as their perceptions and expenditures for malaria prevention and to examine the implications for scaling-up ITNs in rural Nigeria. METHODS: Nine focus group discussions (FGDs) and questionnaires to 798 respondents from three malaria hyper-endemic villages from Enugu state, south-east Nigeria were the study tools. RESULTS: There was a broad spectrum of malaria preventive tools being used by people. The average monthly expenditure on malaria prevention per household was 55.55 Naira ($0.4). More than 80% of the respondent had never purchased any form of untreated mosquito net. People mostly preferred centralized community-based sales of the ITNS, with instalment payments. CONCLUSION: People were knowledgeable about malaria and the beneficial effects of using nets to protect themselves from the disease. The mostly preferred community-based distribution of ITNs implies that the strategy is a potential untapped additional channel for scaling-up ITNs in Nigeria and possibly other parts of sub-Saharan Africa
