A review of the incidence and determinants of catastrophic health expenditure in Nigeria: Implications for universal health coverage

Long-term effects of establishing outpatient pooling funds on financial protection: Empirical evidence from a quasi-natural experiment in China

BACKGROUND

A limited benefit package for outpatient care in Chinese universal health coverage led to high out-of-pocket outpatient payments, and even medical impoverishment. The outpatient pooling fund model was introduced in China's Urban Employee Basic Medical Insurance to reduce cost-sharing for outpatient care. This study attempts to examine the dynamic effects of the outpatient pooling scheme on financial risk protection for its enrollees.

METHODS

A total of 18,097 individual-level observations covering 52 prefectures were extracted from six waves of China Health and Nutrition Survey (2000-2015). The difference-in-differences model with multiple periods and event study were employed to investigate the dynamic effects of reform on catastrophic health expenditure (CHE) and impoverishing health expenditure (IHE) and potential mechanisms.

RESULTS

Our results showed outpatient pooling scheme generated a significant effect on reducing the probability of incurring CHE (β = -0.004, 95% CI = -0.009 to -0.006) and IHE (β = -0.007, 95% CI = -0.012 to -0.001), especially for elderly people over 60 years old. The realization of this effect may depend on the reduction of outpatient cost-sharing, increased outpatient care utilization, as well as decreased inpatient care utilization after reform. However, event study found the effectiveness of outpatient pooling reducing CHE and IHE occurrences appeared to be weak even insignificant in more recent years relative to the initial years of policy implementation.

CONCLUSIONS

Establishing an outpatient pooling system is effective to alleviate the financial risk caused by health expenditures in China. Optimising health service delivery aimed at enhancing health insurance purchasing efficiency are deemed imperative for sustaining the policy effectiveness.

Determinants of health insurance coverage among women in Mauritania: a multilevel analysis

BACKGROUND

Health insurance has been documented as one of the primary methods of financing healthcare for Sustainable Development Goals (SDGs) by 2030. Yet, there is a dearth of evidence on the determinants of health insurance coverage among women in Mauritania. We examine the factors associated with health insurance coverage among women in Mauritania using a nationally representative survey dataset.

METHODS

We analyzed secondary data from the 2019-2021 Mauritania Demographic and Health Survey. A weighted sample of 15,714 women of reproductive age (15-49 years) was included in the study. Multilevel regression analysis was used to examined the factors associated with health insurance coverage. The results were presented using an adjusted odds ratio (aOR) with a 95% confidence interval (CI).

RESULTS

The coverage of health insurance among women was 8.7%. The majority of the women subscribed to social security health insurance (7.6%). Women aged 35 years and above [aOR = 1.54; 95% CI = 1.24, 1.92] were more likely to be covered by health insurance relative to those aged 15-24. The likelihood of being covered by health insurance increased with increasing level of education with the highest odds among women with higher education [aOR = 6.09; 95% CI = 3.93, 9.42]. Women in the richest wealth index households [aOR = 22.12; 95% CI = 9.52, 51.41] and those with grand parity [aOR = 2.16; 95% CI = 1.62, 2.87] had the highest odds of being covered by health insurance. Women who were working, those who watched television, and those who used the internet were more likely to be covered by health insurance relative to their counterparts who were not working, those who did not watch television, and those who did not use the internet. Women residing in Tiris zemour et Inchiri [aOR = 3.60; 95%CI = 1.60, 8.10], Tagant (aOR = 3.74; 95% CI = 1.61, 8.68], and Adrar [aOR = 2.76; 95% CI = 1.36, 5.61] regions were more likely to be covered by health insurance compared with those from Hodh Echargui.

CONCLUSION

Health insurance coverage among the women in our study was low. Achieving the SDG targets of ensuring universal health coverage and lowering maternal mortality to less than 70 deaths per 100,000 live births requires the implementation of interventions to increase health insurance coverage, taking into consideration the identified factors in the study. We recommend effective public education and awareness creation on the importance of being covered by health insurance by leveraging television and internet platforms. Also, interventions to increase health insurance coverage should consider younger women and those in rural areas.

Experiences of membership in munno mubulwadde (your friend indeed) - a novel community-based health insurance scheme in Luwero district in rural central Uganda

BACKGROUND

Community-Based Health Insurance (CBHI) schemes are recognized as an important health financing pathway to achieving universal health coverage (UHC). Although previous studies have documented CBHIs in low-income countries, the majority of these have been provider-based. Non-provider based schemes have received comparatively less empirical attention. We sought to describe a novel non-provider based CBHI munno mubulwadde (your friend indeed) comprising informal sector members in rural central Uganda to understand the structure of the scheme, the experiences of scheme members in terms of the perceived benefits and barriers to retention in the scheme.

METHODS

We report qualitative findings from a larger mixed-methods study. We conducted in-depth interviews with insured members (n = 18) and scheme administrators (n = 12). Four focus groups were conducted with insured members (38 participants). Data were inductively analyzed by thematic approach.

RESULTS

Munno mubulwadde is a union of ten CBHI schemes coordinated by one administrative structure. Members were predominantly low-income rural informal sector households who pay annual premiums ranging from $17 and $50 annually and received medical care at 13 scheme-contracted private health facilities in Luwero District in Central Uganda. Insured members reported that scheme membership protected them from catastrophic health expenditure during episodes of sickness among household members, and especially so among households with children under-five who were reported to fall sick frequently, the scheme enabled members to receive perceived better quality health care at private providers in the study district relative to the nearest public facilities. The identified barriers to retention in the scheme include inconvenient dates for premium payment that are misaligned with harvest periods for cash crops (e.g. maize corn) on which members depended for their agrarian livelihoods, long distances to insurance-contracted private providers, falling prices of cash crops which diminished real incomes and affordability of insurance premiums in successive years after initial enrolment.

CONCLUSION

Munno mubulwadde was perceived by as a valuable financial cushion during episodes of illness by rural informal sector households. Policy interventions for promoting price stability of cash crops in central Uganda could enhance retention of members in this non-provider CBHI which is worthy of further research as an additional funding pathway for realizing UHC in Uganda and other low-income settings.

Catastrophic health expenditure and its inequality in rural China: based on longitudinal data from 2013 to 2018

BACKGROUND

Catastrophic health expenditure (CHE) is an important indicator of measuring health inequality. Previous studies mainly focused on specific vulnerable populations rather than a wider range of vulnerable areas through panel data. Rural China is often associated with an underdeveloped economy and insufficient health resources. This study aims to update the information on the extent of and trends in the incidence and inequality of CHE among the households of rural China through longitudinal survey data.

METHODS

Data were obtained from three waves of the China Health and Retirement Longitudinal Study (CHARLS): 2013, 2015, and 2018. In total, 2,575 households were included in the analysis. CHE was defined as household health expenditures exceeding 40% of non-food expenditures. Inequality in CHE was measured using the concentration curve and concentration index. The contribution to CHE inequality was decomposed using the concentration index decomposition method.

RESULTS

The incidence of CHE was 0.2341 (95% CI: 0.22, 0.25) in 2013, 0.2136 (95% CI: 0.20, 0.23) in 2015, and 0.2897 (95% CI: 0.27, 0.31) in 2018 in rural China. The concentration curve lay above the equality line, and the concentration index was negative: -0.1528 (95% CI: -0.1941, -0.1115) in 2013, -0.1010 (95% CI: -0.1442, -0. 0577) in 2015, and -0.0819 (95% CI: -0.1170, -0.0467) in 2018. Economic status, age, and chronic diseases were the main contributors to inequality in CHE.

CONCLUSIONS

The incidence of CHE in rural China displayed an upward trend from 2013 to 2018, although it was not continuous. Furthermore, a strong pro-low-economic inequality in CHE existed in rural China. Mainly economic status, age, and chronic diseases contributed to this pro-low-economic inequality. Health policies to allocate resources and services are needed to satisfy the needs of rural households and provide more accessible and affordable health services. More concern needs to be directed toward households with chronic diseases and older persons to reduce the incidence of CHE and promote health equality.

Economic burden of non-communicable diseases on households in Nigeria: evidence from the Nigeria living standard survey 2018-19

BACKGROUND

The importance of non-communicable diseases (NCDs) in Nigeria is reflected in their growing burden that is fast overtaking that of infectious diseases. As most NCD care is paid for through out-of-pocket (OOP) expenses, and NCDs tend to cause substantial income losses through chronic disabilities, the rising NCD-related health burden may also be economically detrimental. Given the lack of updated national-level evidence on the economic burden of NCDs in Nigeria, this study aims to produce new evidence on the extent of financial hardship experienced by households with NCDs in Nigeria due to OOP expenditure and productivity loss.

METHODS

This study analysed cross-sectional data from the most recent round (2018-19) of the Nigeria Living Standard Survey (NLSS). Household-level health and consumption data were used to estimate catastrophic health expenditure (CHE) and impoverishing effects due to OOP health spending, using a more equitable method recently developed by the World Health Organization European region in 2018. The productivity loss by individuals with NCDs was also estimated from income and work-time loss data, applying the input-based human capital approach.

RESULTS

On average, a household with NCDs spent ₦ 122,313.60 or $ 398.52 per year on NCD care, representing 24% of household food expenditure. The study found that OOP on cancer treatment, mental problems, and renal diseases significantly contribute to the cost of NCD care. The OOP expenditure led to catastrophic and impoverishing outcomes for households. The estimations showed that about 30% of households with NCDs experienced CHE in 2018, using the WHO Europe method at the 40% threshold. The study also found that the cost of NCD medications was a significant driver of CHE among NCD-affected households. The results showed heterogeneity in CHE and impoverishment across states and geographical regions in Nigeria, with a higher concentration in rural and North East geopolitical locations. The study also found that 20% of NCD-affected households were impoverished or further impoverished by OOP payment, and another 10% were on the verge of impoverishment. The results showed a negligible rate of unmet needs among households with NCDs.

CONCLUSIONS

The study highlights the significant effect of NCDs on Nigerian households and the need for effective policy interventions to address this challenge, particularly among the poor and vulnerable.

Catastrophic health-care payments and multidimensional poverty: Are they related?

The negative impact of health-related out-of-pocket (OOP) payments is a well-known problem in low and middle-income countries (LMICs). Cross-sectional analysis reveals that households use different coping mechanisms to mitigate or overcome the effect of OOP payments, but little is known from a longitudinal perspective. We explore this link using panel data for Colombia, Mexico, India, Malawi, Nigeria, Uganda, and Tanzania. Using a fixed-effect model, we computed the association between multidimensional poverty (MP) and facing catastrophic health payments (CHP) using a capacity-to-pay approach. We estimated different heterogeneous effects, including variables such as area of residence, facing CHP, being poor in the first wave, and facing CHP in period two. While using cross-sectional data, we found that the association between CHP and MP is present for six of the seven countries; it is not the case for the time variation in most of them. The results provide evidence that OOP induce a long-term impact on MP only in Colombia, India and Nigeria. In the last two countries, the levels of poverty and CHP were the highest of all seven, and the association between both situations was found by using different poverty cutoffs and thresholds to define CHP.

Stated preferences for human papillomavirus vaccination for adolescents in selected communities in Ibadan, Southwest Nigeria: A discrete choice experiment

Administration of the human papillomavirus (HPV) vaccine in early adolescence is effective in preventing cervical cancer, a common cancer in sub-Saharan Africa. Nigeria is in the pre-introduction era of the HPV vaccine. Understanding the preferences of the population for the vaccine can help design the HPV immunization program to ensure high uptake of the vaccine. This study explored the preferences for the HPV vaccine among stakeholders in selected communities in Ibadan, Nigeria. A discrete choice experiment survey based on six attributes of the HPV vaccine (which were the number of doses, the efficacy of the vaccine, cost of the vaccine, location of the service point, other benefits of the vaccine apart from prevention of cervical cancer and the odds of a side effect from the vaccine) was carried out in five communities. Data were analyzed using conditional and mixed logit models. Seven hundred community members were recruited, 144 (20.7%) were adolescents and 248 (35.4%) were males. In line with expectations, respondents preferred vaccines with higher efficacy, less severe side effects and lower costs. Preference heterogeneity was identified for adolescents that were less price-sensitive and other community members who were less likely to prefer using schools as the service point. The high socioeconomic class preferred a vaccine that also prevents genital warts. There were variabilities in the preferences for the attributes of the HPV vaccine in the study communities. These variabilities need to be considered in the introduction of the HPV vaccine to ensure high uptake of the vaccine.

Towards the achievement of universal health coverage in the Democratic Republic of Congo: does the Country walk its talk?

In 2009, the Democratic Republic of Congo (DRC) started its journey towards achieving Universal Health Coverage (UHC). This study examines the evolution of financial risk protection and health outcomes indicators in the context of the commitment of DRC to UHC. To measure the effects of such a commitment on financial risk protection and health outcomes indicators, we analyse whether changes have occurred over the last two decades and, if applicable, when these changes happened. Using five variables as indicators for the measurement of the financial risk protection component, there as well retained three indicators to measure health outcomes. To identify time-related effects, we applied the parametric approach of breakpoint regression to detect whether the UHC journey has brought change and when exactly the change has occurred.Although there is a slight improvement in the financial risk protection indicators, we found that the adopted strategies have fostered access to healthcare for the wealthiest quantile of the population while neglecting the majority of the poorest. The government did not thrive persistently over the past decade to meet its commitment to allocate adequate funds to health expenditures. In addition, the support from donors appears to be unstable, unpredictable and unsustainable. We found a slight improvement in health outcomes attributable to direct investment in building health centres by the private sector and international organizations. Overall, our findings reveal that the prevention of catastrophic health expenditure is still not sufficiently prioritized by the country, and mostly for the majority of the poorest. Therefore, our work suggests that DRC's UHC journey has slightly contributed to improve the financial risk protection and health outcomes indicators but much effort should be undertaken.

Exploring dynamics in catastrophic health care expenditure in Nigeria

BACKGROUND

The Nigeria's National Health Insurance Scheme aimed at making health care accessible and affordable since it's became operational in 2005. However, many Nigerians still pay out of pocket for medical expenses, and this drive them to incurring catastrophic health expenditures. Although monitoring progress towards UHC is crucial, one single study exploring the dynamics in catastrophic health expenditure proportion, associated factors, inequality concentration, inequality size, together with decomposition using a longer period Nigeria panel household survey datasets is very scarce.

METHODS

Data was drawn from three rounds of the Nigeria General Household Survey. The fixed percentage and rank-dependent thresholds were used to calculate and compare the proportion of households that incur catastrophic health expenditures. The logistic regression model was employed in analyzing the factors associated with catastrophic health expenditures. The concentration of catastrophic health expenditures inequality was assessed using the concentration curve, whereas the inequality size was determined using the concentration index. The decomposition method was used to decompose the concentration index into determining components.

RESULTS

Relative to the fixed threshold value, the rank-dependent threshold revealed a higher share of households facing catastrophic health expenditures i.e., from 27% in 2010/2011 to 48% in 2015/2016. The two thresholds reveal similar trend, but differ in percentage points. The key factors associated with catastrophic health expenditures were economic status and geopolitical zone. Inequality in catastrophic health expenditures was found to be concentrated among the poor. The household economic status was uncovered as the major positive contributor to catastrophic health expenditures inequality across the sample periods.

CONCLUSION

The findings of the study imply that narrowing economic status gap across households, and increasing the depth of insurance are crucial mechanisms to reduce the probability of incurring catastrophic health expenditures among the poor in Nigeria.

Identifying priorities for research on financial risk protection to achieve universal health coverage: a scoping overview of reviews

OBJECTIVES

Financial risk protection (FRP) is an indicator of the Sustainable Development Goal 3 universal health coverage (UHC) target. We sought to characterise what is known about FRP in the UHC context and to identify evidence gaps to prioritise in future research.

DESIGN

Scoping overview of reviews using the Arksey & O'Malley and Levac & Colquhoun framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews reporting guidelines.

DATA SOURCES

MEDLINE, PsycINFO, CINAHL-Plus and PAIS Index were systematically searched for studies published between 1 January 1995 and 20 July 2021.

ELIGIBILITY CRITERIA

Records were screened by two independent reviewers in duplicate using the following criteria: (1) literature review; (2) focus on UHC achievement through FRP; (3) English or French language; (4) published after 1995 and (5) peer-reviewed.

DATA EXTRACTION AND SYNTHESIS

Two reviewers extracted data using a standard form and descriptive content analysis was performed to synthesise findings.

RESULTS

50 studies were included. Most studies were systematic reviews focusing on low-income and middle-income countries. Study periods spanned 1990 and 2020. While FRP was recognised as a dimension of UHC, it was rarely defined as a concept. Out-of-pocket, catastrophic and impoverishing health expenditures were most commonly used to measure FRP. Pooling arrangements, expansion of insurance coverage and financial incentives were the main interventions for achieving FRP. Evidence gaps pertained to the effectiveness, cost-effectiveness and equity implications of efforts aimed at increasing FRP. Methodological gaps related to trade-offs between single-country and multicountry analyses; lack of process evaluations; inadequate mixed-methods evidence, disaggregated by relevant characteristics; lack of comparable and standardised measurement and short follow-up periods.

CONCLUSIONS

This scoping overview of reviews characterised what is known about FRP as a UHC dimension and found evidence gaps related to the effectiveness, cost-effectiveness and equity implications of FRP interventions. Theory-informed mixed-methods research using high-quality, longitudinal and disaggregated data is needed to address these objectives.

The cost of illness for childhood clinical pneumonia and invasive pneumococcal disease in Nigeria

BACKGROUND

Pneumococcal disease contributes significantly to childhood morbidity and mortality and treatment is costly. Nigeria recently introduced the pneumococcal conjugate vaccine (PCV) to prevent pneumococcal disease. The aim of this study is to estimate health provider and household costs for the treatment of pneumococcal disease in children aged <5 years (U5s), and to assess the impact of these costs on household income.

METHODS

We recruited U5s with clinical pneumonia, pneumococcal meningitis or pneumococcal septicaemia from a tertiary level hospital and a secondary level hospital in Kano, Nigeria. We obtained resource utilisation data from medical records to estimate costs of treatment to provider, and household expenses and income loss data from caregiver interviews to estimate costs of treatment to households. We defined catastrophic health expenditure (CHE) as household costs exceeding 25% of monthly household income and estimated the proportion of households that experienced it. We compared CHE across tertiles of household income (from the poorest to least poor).

RESULTS

Of 480 participants recruited, 244 had outpatient pneumonia, and 236 were hospitalised with pneumonia (117), septicaemia (66) and meningitis (53). Median (IQR) provider costs were US$17 (US$14-22) for outpatients and US$272 (US$271-360) for inpatients. Median household cost was US$51 (US$40-69). Overall, 33% of households experienced CHE, while 53% and 4% of the poorest and least poor households, experienced CHE, respectively. The odds of CHE increased with admission at the secondary hospital, a diagnosis of meningitis or septicaemia, higher provider costs and caregiver having a non-salaried job.

CONCLUSION

Provider costs are substantial, and households incur treatment expenses that considerably impact on their income and this is particularly so for the poorest households. Sustaining the PCV programme and ensuring high and equitable coverage to lower disease burden will reduce the economic burden of pneumococcal disease to the healthcare provider and households.

Prevalence and factors associated with catastrophic health expenditure among slum and non-slum dwellers undergoing emergency surgery in a metropolitan area of South Western Nigeria

BACKGROUND

Out of Pocket (OOP) payment continues to persist as the major mode of payment for healthcare in Nigeria despite the introduction of the National Health Insurance Scheme (NHIS). Although the burden of health expenditure has been examined in some populations, the impact of OOP among slum dwellers in Nigeria when undergoing emergencies, is under-researched. This study sought to examine the prevalence, factors and predictors of catastrophic health expenditure amongst selected slum and non-slum communities undergoing emergency surgery in Southwestern Nigeria.

METHODS

The study utilised a descriptive cross-sectional survey design to recruit 450 households through a multistage sampling technique. Data were collected using pre-tested semi-structured questionnaires in 2017. Factors considered for analysis relating to the payer were age, sex, relationship of payer to patient, educational status, marital status, ethnicity, occupation, income and health insurance coverage. Variables factored into analysis for the patient were indication for surgery, grade of hospital, and type of hospital. Households were classified as incurring catastrophic health expenditure (CHE), if their OOP expenditure exceeded 5% of payers' household budget. Analysis of the data took into account the multistage sampling design.

RESULTS

Overall, 65.6% (95% CI: 55.6-74.5) of the total population that were admitted for emergency surgery, experienced catastrophic expenditure. The prevalence of catastrophic expenditure at 5% threshold, among the population scheduled for emergency surgeries, was significantly higher for slum dwellers (74.1%) than for non-slum dwellers (47.7%) (F = 8.59; p = 0.019). Multiple logistic regression models revealed the significant independent factors of catastrophic expenditure at the 5% CHE threshold to include setting of the payer (whether slum or non-slum dweller) (p = 0.019), and health insurance coverage of the payer (p = 0.012). Other variables were nonetheless significant in the bivariate analysis were age of the payer (p = 0.017), income (p<0.001) and marital status of the payer (p = 0.022).

CONCLUSION

Although catastrophic health expenditure was higher among the slum dwellers, substantial proportions of respondents incurred catastrophic health expenditure irrespective of whether they were slum or non-slum dwellers. Concerted efforts are required to implement protective measures against catastrophic health expenditure in Nigeria that also cater to slum dwellers.

Examining the distribution of benefits of a free Maternal and Child Health programme in Enugu State, Nigeria: a benefit incidence analysis

OBJECTIVE

To determine the population groups that benefit from a Free Maternal and Child Health (FMCH) programme in Enugu State, South-east Nigeria, so as to understand the equity effects of the programme.

METHOD

A community-based survey was conducted in rural and urban local government areas (LGAs) to aid the benefit incidence analysis (BIA) of the FMCH. Data were elicited from 584 randomly selected women of childbearing age. Data on their level of utilisation of FMCH services and their out-of-pocket expenditures on various FMCH services that they utilised were elicited. Benefits of the FMCH were valued using the unit cost of providing services while the net benefit was calculated by subtracting OOP expenditures made for services from the value of benefits. Costs were calculated in local currency (Naira (₦)) and converted to US Dollars. The net benefits were disaggregated by urban-rural locations and socio-economic status (SES). Concentration indices were computed to provide the level of SES inequity in BIA of FMCH.

RESULTS

The total gross benefit incidence was ₦2.681 million ($7660). The gross benefit that was consumed by the urban dwellers was ₦1.581 million ($4517.1), while the rural dwellers consumed gross benefits worth ₦1.1 million ($3608.20). However, OOP expenditure for the supposedly FMCH was ₦6 527 580 (US$18 650.2) in the urban area, while it was ₦3, 194, 706 (US$ 9127.7) among rural dwellers. There was negative benefit incidence for the FMCH because the OOP exceeded the gross benefits at the point of use of services. There was no statistically significant difference in the benefit incidence and OOP expenditure between the urban and rural dwellers and across socio-economic groups.

CONCLUSION

The distribution of the gross benefits of the FMCH programme indicates that it may not have achieved the desired aim of enhanced access particularly to the low-income population. Crucially, the high level of OOP erased whatever societal gain the FMCH was developed to provide. Hence, there is a need to review its implementation and re-strategise to reduce OOP and achieve greater access for improved effectiveness of the programme.
