The differences in characteristics between health-care users and non-users: implication for introducing community-based health insurance in Burkina Faso.

The purposes of this study are to describe the characteristics of different health-care users, to explain such characteristics using a health demand model and to estimate the price-related probability change for different types of health care in order to provide policy guidance for the introduction of community-based health insurance (CBI) in Burkina Faso. Data were collected from a household survey using a two stage cluster sampling approach. Household interviews were carried out during April and May 2003. In the interviewed 7,939 individuals in 988 households, there were 558 people reported one or more illness episodes; two-thirds of these people did not seek professional care. Health care non-users display lower household income and expenditure, older age and lower perceived severity of disease. The main reason for choosing no-care and self-care was 'not enough money'. Multinomial logistic regression confirms these observations. Higher household cash-income, higher perceived severity of disease and acute disease significantly increased the probability of using western care. Older age and higher price-cash income ratio significantly increased the probability of no-care or self-care. If CBI were introduced the probability of using western care would increase by 4.33% and the probability of using self-care would reduce by 3.98%. The price-related probability change of using western care for lower income people is higher than for higher income although the quantity changed is relatively small. In conclusion, the introduction of CBI might increase the use of medical services, especially for the poor. Co-payment for the rich might be necessary. Premium adjusted for income or subsidies for the poor can be considered in order to absorb a greater number of poor households into CBI and further improve equity in terms of enrollment. However, the role of CBI in Burkina Faso is rather limited: it might only increase utilisation of western health care by a probability of 4%.

Biomass solid fuel and acute respiratory infections: the ventilation factor.

Biomass solid fuel smoke is linked to acute respiratory infections (ARI). In future, its use will likely increase among poor households, and better ventilation is one important measure that can reduce this health impact. The authors aimed to study the extent to which improvement in ventilation-related factors reduces the fraction of ARI attributable to exposure to biomass smoke in children under 5 years old. An explorative study was carried out in 2004 by applying a questionnaire on 51 households randomly selected from a health district in Burkina Faso. The prevalence of exposure in the population was estimated using ventilation coefficients, and proportions of households with different stove types and locations. An attributable fraction of 0.56 (95% CI: 0.47-0.62) was estimated using the traditional formula for attributable fraction, and 0.26 (95% CI: 0.19-0.31) after weighting exposure by ventilation coefficients, stove type and location. Two scenarios were created: (1) Assuming that most households cooked inside, the fraction becomes 0.54 (95% CI: 0.45-0.61). (2) Assuming that indoor ventilation and cooking device are improved by 20%, the fractions decreased slightly. Improving cooking devices and indoor ventilation reduces the fraction of ARI in children under 5 years attributable to exposure to biomass smoke, but a higher reduction is achieved by cooking outdoors.

Housing conditions and Plasmodium falciparum infection: protective effect of iron-sheet roofed houses.

BACKGROUND: Identification and better understanding of potential risk factors for malaria are important for targeted and cost-effective health interventions. Housing conditions have been suggested as one of the potential risk factors. This study aims to further investigate this risk factor, and is focused on the effect of the type of roof on Plasmodium falciparum infection among children below five years in the North West of Burkina Faso. METHODS: In a cross-sectional study design, 661 children aged six to 60 months were randomly selected from three rural and one semi-urban site at the end of the rainy season (November 2003). The children were screened for fever and tested for Plasmodium falciparum infection. In addition, data on bed net use and house characteristics was collected from the household were each child lived. Using adjusted odds ratios, children living in house roofed with iron-sheet were compared with those in house with mud or grass roof. RESULTS: Overall P. falciparum infection prevalence was 22.8 % with a significant variation between (Chi-square, p < 0.0001). The prevalence in Cissé (33.3 %) and Goni (30.6 %) were twice times more than in Nouna (15.2 %) and Kodougou (13.2 %). After adjusting for age, sex, use of bed net and housing conditions, children living in houses with mud roofs had significantly higher risk of getting P. falciparum infection compared to those living in iron-sheet roofed houses (Odds Ratio 2.6; 95% Confidence Interval, 1.4-4.7). CONCLUSION: These results suggest that house characteristics should be taken into consideration when designing health intervention against P. falciparum infection and particular attention should be paid to children living in houses with mud roofs.

Understanding enrolment in community health insurance in sub-Saharan Africa: a population-based case-control study in rural Burkina Faso.

OBJECTIVE: To identify factors associated with decision to enrol in a community health insurance (CHI) scheme. METHODS: We conducted a population-based case-control study among 15 communities offered insurance in 2004 in rural Burkina Faso. For inclusion in the study, we selected all 154 enrolled (cases) and a random sample of 393 non-enrolled (controls) households. We used unconditional logistic regression (applying Huber-White correction to account for clustering at the community level) to explore the association between enrolment status and a set of household head, household and community characteristics. FINDINGS: Multivariate analysis revealed that enrolment in CHI was associated with Bwaba ethnicity, higher education, higher socioeconomic status, a negative perception of the adequacy of traditional care, a higher proportion of children living within the household, greater distance from the health facility, and a lower level of socioeconomic inequality within the community, but not with household health status or previous household health service utilization. CONCLUSION: Our study provides evidence that the decision to enrol in CHI is shaped by a combination of household head, household, and community factors. Policies aimed at enhancing enrolment ought to act at all three levels. On the basis of our findings, we discuss specific policy recommendations and highlight areas for further research.

"To enrol or not to enrol?": A qualitative investigation of demand for health insurance in rural West Africa.

In spite of the fact that feeble levels of participation have long been identified as a major constraint to the successful long-term implementation of community-based health insurance (CBI) in low-income countries, evidence on determinants of enrolment in CBI is still lacking. The application of econometric modelling has provided a partial answer to the question, but on its own it has proved to be insufficient to guide policy making. This paper aims to fill this gap in knowledge using qualitative research methods. In-depth interviews with 32 household heads were conducted in the Nouna Health District, Burkina Faso, West Africa to assess determinants of enrolment in a newly established CBI scheme. The findings highlight that factors previously neglected in the literature, such as institutional rigidities and socio-cultural practices, play an important role in shaping the decision to enrol. The discussion of the findings focuses on the policy implications, offering concrete recommendations to maximise enrolment, within and beyond Burkina Faso.

Modelling the effectiveness of financing policies to address underutilization of children's health services in Nepal.

OBJECTIVE: To estimate the price responsiveness of utilization of formal children's health-care services in Nepal and to use this information to model the impact on utilization of subsidies or increases in user fees. METHODS: A total of 8112 individual observations (of children aged < 15 years) from 2847 households in 274 communities were obtained from the 1996 Nepal Living Standards Survey. A logit model was applied to determine the net impact of price on a parent or caregiver's decision to seek care for a given instance of illness. The model's coefficients were used to calculate the price responsiveness of utilization decisions. FINDINGS: Parents or caregivers reported that 9.7% of children (788/8112) had been ill or injured in the previous month. Parents reported that they had sought care in 566 (71.8%) of these cases; care was most frequently sought from public providers. The price elasticity of demand for children's health-care services in the formal sector was estimated at -0.16. As prices rise, the demand curve exhibits continuous and declining price elasticity. Overall, a 100% subsidy of user fees would increase current utilization rates by 56%, while a 100% increase in fees would lead to a drop in utilization of only 12%. The differential in utilization across income groups was substantial after changes in fees were implemented. CONCLUSION: While the effect of price on the utilization of children's health-care services in Nepal is statistically significant, the size of the impact is modest. Policies to subsidize fees could increase utilization substantially, while fee increases would lead to modest declines in utilization and generate increased revenue.

Understanding consumers' preferences and decision to enrol in community-based health insurance in rural West Africa.

This paper presents a qualitative investigation of consumers' preferences regarding the single elements of a community-based health insurance (CBI) scheme recently implemented in a rural region in west Africa. The aim is to provide adequate policy-guidance to decision makers in low and middle income countries by producing an in-depth understanding of how consumers' preferences may affect decision to participate in such schemes. Although it has long been suggested that feeble levels of participation may very well be an expression of consumers' dissatisfaction with scheme design, little systematic efforts have so far been channelled towards supporting such argument with empirical evidence. Consumers' preferences were explored through means of 32 individual interviews with household heads. Analysis used the method of constant comparison and was conducted by two independent researchers. Data from 10 focus group discussions provided an additional valuable source of triangulation. Findings suggest that decision to enrol is closely linked to whether the single elements of the scheme match consumers' needs and expectations. In particular, consumers justified decision to join or not to join the insurance scheme in relation to their preference for the unit of enrolment, the premium level and the payment modalities, the benefit package, the health service provider network and the CBI managerial structure. The discussion of the findings focuses on how understanding consumers' preferences and incorporating them in the design of a CBI scheme may result in increased participation rates, ensuring that poor populations gain better access to health services and enjoy greater protection against the cost of illness.

Gender role and child health care utilization in Nepal.

OBJECTIVE: To study the gender role in child health care utilization in Nepal. METHODS: We analysed 8112 individual observations of age </=15 years from 2847 households in 274 communities, obtained from the 1996 Nepal Living Standard Survey. Four steps of a health seeking action, namely illness reporting, choosing an external care, choosing a specific health care provider, and spending money to treat the sick child, were examined using discrete/continuous choice models. RESULTS: There was no statistically significant difference between boys and girls by demographic, socio-economic and geographical status in the sample. However, gender was associated with all four utilization decision steps. While the net effect of being a boy was modest in illness reporting (p<0.10), it appeared stronger in the choice of external care, in the choice of public provider and in the choice of expenditure with the private provider (p<0.05). CONCLUSION: Gender role not only affects illness reporting but also affects the decision to choose a health care provider and how much to spend on the sick child, i.e. it affects the entire steps of a health seeking action.

Inequality in willingness-to-pay for community-based health insurance.

The purpose was to provide information for devising community-based health insurance (CBI) policies that reduce inequality in enrolment and further inequality in access to health services. A two-stage cluster sampling was used in the household survey. Inequalities in willingness-to-pay (WTP) for CBI are examined by expenditure quintile using data collected from a household survey. Interviews were conducted with 2414 individuals, 705 of whom were household heads. A bidding game method was used to elicit WTP. Individuals and households were assigned to 6-month expenditure quintiles. We found that mean and median individual WTP for CBI was significantly higher for higher spending quintiles, as was mean and median household WTP. The curves of cumulative percentage of individual and household WTP shifted rightwards for higher quintiles, implying that at any given premium the lower the quintile the lower the uptake of CBI. The Gini coefficient for individual WTP and household WTP was 0.15 and 0.08, respectively, and for individual 6-month expenditure and household 6-month expenditure is 0.68 and 0.63, respectively. The results imply that the premium needs to be adjusted for income; otherwise, a lower proportion of poor people will enrol in CBI and without exemptions or subsidies the poor will have less access to health services than the rich. Thus, exemptions and subsidies for the poor for enrolling in CBI are an important issue for decision-makers with an objective of improving equity of health and helping the poor to break out of the cycle of poverty. Since the distribution of WTP by household is less unequal than the distribution of WTP by individuals, the household might be a better unit of enrolment in terms of equity than the individual.

Willingness to pay for hypothetical malaria vaccines in rural Burkina Faso.

AIMS: This study aims to set priorities for anti-disease malaria vaccines by determining community preference in a hyperendemic area. METHODS: A bidding game technique was used to elucidate willingness to pay in rural Burkina Faso and 2,326 adults were interviewed. RESULTS: It is shown that there are significant differences between community preference for an anti-disease vaccine aimed at reducing pathology in pregnant women, and for a vaccine directed against childhood malaria. While the target population was willing to pay CFAfr 2101 for a vaccine against maternal malaria, its members were prepared to pay only CFAfr 1433 for a vaccine against childhood malaria. CONCLUSIONS: Whilst it is increasingly likely that anti-disease malaria vaccines will become available in the foreseeable future, lessons from the past suggest that a lack of acceptance and support from the intended recipients may lead to less than optimal compliance, and hence efficacy. For the planning of vaccine development and application strategies, it is therefore highly important to take community views into account. Here it is argued that such information could help researchers and funding agencies to set priorities for future vaccine research.

The two faces of enhancing utilization of health-care services: determinants of patient initiation and retention in rural Burkina Faso.

OBJECTIVE: To explore the factors that determine whether a patient will initiate treatment within a system of health-care services, and the factors that determine whether the patient will be retained in the chosen system, in Nouna, rural Burkina Faso. METHODS: The data used were pooled from four rounds of a household survey conducted in Nouna, rural Burkina Faso. The ongoing demographic surveillance system provided a sampling framework for this survey in which 800 households were sampled using a two-stage cluster sampling procedure. More than one treatment episode was observed for a single episode of illness per patient. The multinomial logit model was used to explore the determinants of patient initiation to systems of modern, traditional and home treatment, and a binary logit model was used to explore the determinants of patient retention within the chosen health-care provider system. FINDINGS: The results suggest that the determinants of patient initiation and their subsequent retention are different. Household income, education, urban residence and expected competency of the provider are positive predictors of initiation, but not of retention, for modern health-care services. Only perceived quality of care positively predicted retention in modern health-care services. CONCLUSION: Interventions focusing on patient initiation and patient retention are likely to be different. Policies directed at enhancing initiation for modern health-care services would primarily focus on reducing financial barriers, while those directed at increasing retention would primarily focus on attributes that improve the perceived quality of care.

The feasibility of community-based health insurance in Burkina Faso.

To ensure the acceptability of community-based insurance (CBI) by the community and its sustainability, a feasibility study of CBI was conducted in Burkina Faso, including preference for benefit package of CBI, costing of health services, costing of the benefit package and willingness-to-pay (WTP) for the package. Qualitative methods were used to collect information about preferences for the benefit package. Cost per unit health services, health demand obtained from household survey and physician-judged health needs were used to estimate the cost of the benefit package. The bidding game method was used to elicit household head's WTP for the package. We found that there were strong preferences for inclusion of high-cost healthservices such as operation, essential drugs and consultation fees in the benefit package. It is estimated that the cost of the package per capita was 1673 CFA (demand-based) and 9630 CFA (need-based), including 58% government subsidies (euro 1 = 655 CFA). The average household head with eight household members agreed to pay from 7500 (median) to 9769 CFA (mean) to join the CBI for his/her household. The WTP results were influenced by household characteristics, such as location, household size and age composition. Under certain assumptions (household as the enrolment unit, median household head's WTP as premium for the average household, 50% enrolment rate), it would be feasible to run CBI in Nouna, Burkina Faso if enrolees' health demand did not increase by more than 28% or if the underwriting of the initial losses was covered by extra funds.

Differential willingness of household heads to pay community-based health insurance premia for themselves and other household members.

OBJECTIVE: This study compares household heads' willingness-to-pay (WTP) for community-based health insurance (CBI) for themselves with their WTP for other household members, in order to provide information for policy makers on setting the premium and choosing the enrollment unit. METHOD: A random sample of 698 heads of households was interviewed in the northwest of Burkina Faso and a bidding game approach was used to elicit WTP. Factors associated with differences in WTP were identified, including characteristics of the household head and of the household. RESULTS: Mean WTP by the heads of households for insurance for themselves (3575 CFA) was twice their mean WTP per capita for the household as a whole (1759 CFA). The old have a lower WTP than the young, females have lower WTP than males, the poor have a lower WTP than the rich, and that those with less schooling have a lower WTP than those with more years of schooling. CONCLUSION: The differences in household heads' WTP for insurance for themselves and their WTP to insure their households as a whole need to be considered when setting the insurance premium. WTP information can assist decision makers with the complex problem of choosing the enrollment unit and setting the premium.

Household decision-making on child health care in developing countries: the case of Nepal.

Quantitative studies on health care utilization often overlook the importance of capturing the 'pathway' of household decision-making processes. This paper offers a four-step construct which maps out a hierarchical scale of household decision-making regarding child health care. The construct begins with the perception of illness, moves on to choice of care and provider, and finally ends with health care expenditure. The construct is substantiated by means of a descriptive analysis of nationally representative data from the 1996 round of the Nepal Living Standards Survey. About 10% of the total population reported illness, 69% of whom sought care, and depending upon the provider they chose, spent between 2.5 to 4.3% of their per capita household total annual expenditure on health care. Bivariate analysis detected age and gender biases in the perception of illness, but if a child was reported ill, all subsequent steps were found to be free from such differences. Further analysis, that took into account the changing effects of income and mother's education, indicated that there may be conceptually different household dynamics that underlie boys' and girls' illness perception; this ultimately determines whether or not health care is sought. The authors put forward a hypothesis to be tested by future studies. They argue that gender role significantly affects the perception of illness, but not necessarily the subsequent care-seeking. The relevance of this hypothesis to explaining the typical South Asian characteristic of differential child mortality rates is discussed.

The effects of mandatory health insurance on equity in access to outpatient care in Indonesia.

This paper examines the effects of mandatory health insurance on access and equity in access to public and private outpatient care in Indonesia. Data from the second round of the 1997 Indonesian Family Life Survey were used. We adopted the concentration index as a measure of equity, and this was calculated from actual data and from predicted probability of outpatient-care use saved from a multinomial logit regression. The study found that a mandatory insurance scheme for civil servants (Askes) had a strongly positive impact on access to public outpatient care, while a mandatory insurance scheme for private employees (Jamsostek) had a positive impact on access to both public and private outpatient care. The greatest effects of Jamsostek were observed amongst poor beneficiaries. A substantial increase in access will be gained by expanding insurance to the whole population. However, neither Askes nor Jamsostek had a positive impact on equity. Policy implications are discussed.

Willingness-to-pay for community-based insurance in Burkina Faso.

PURPOSE: To study the willingness-to-pay (WTP) for a proposed community-based health insurance (CBI) scheme in order to provide information about the relationship between the premium that is required to cover the costs of the scheme and expected insurance enrollment levels. In addition, factors that influence WTP were to be identified. METHODS: Data were collected from a household survey using a two-stage cluster sampling approach, with each household having the same probability of being selected. Interviews were conducted with 2414 individuals and 705 household heads. The take-it-or-leave-it (TIOLI) and the bidding game were used to elicit WTP. RESULTS: The average individual was willing to pay 2384 (elicited by the TIOLI) or 3191 (elicited by the bidding game) CFA (3.17 US dollars or 4.25 US dollars) to join CBI for him/herself. The head of household agreed to pay from 6448 (elicited by the TIOLI) or 9769 (elicited by the bidding game) CFA (8.6 US dollars or 13.03 US dollars) to join the health insurance scheme for his/her household. These results were influenced by household and individual ability-to-pay, household and individual characteristics, such as age, sex and education. The two methods yielded similar patterns of estimated WTP, in that higher WTP was obtained for higher income level, higher previous medical expenditure, higher education, younger people and males. A starting point bias was found in the case of the bidding game. CONCLUSIONS: Both TIOLI and bidding game methods can elicit a value of WTP for CBI. The value elicited by the bidding game is higher than by the TIOLI, but the two approaches yielded similar patterns of estimated WTP. WTP information can be used for setting insurance premium. When setting the premiums, it is important to consider differences between the real market and the theoretical one, and between the WTP and the cost of benefits package. The beneficiaries of CBI should be enrolled at the level of households or villages in order to protect vulnerable groups such as women, elders and the poor.
