Background: Every year, 808 million people face catastrophic health expenditure (CHE), and 122 million people were pushed into poverty. It aggravates healthcare inequalities, incurs double burden opportunity costs, and pushes households to sit in a deep poverty trap. A few studies have been done so far; however, it is not enough to inform policy decisions. Therefore, this study aimed to assess the catastrophic out-of-pocket health expenditure and associated factors among rural households in Mandura District, Western Ethiopia.
Methods: We conducted a community-based cross-sectional study among the Mandura district’s 488 rural households from April to May 2017. We used a multistage systematic sampling technique to select the participants. We fitted a binary logistic regression model to identify the factors associated with catastrophic out-of-pocket health expenditure. We used the adjusted odds ratio (AOR) with 95% CI and the p-value < 0.05 to determine the variables associated with catastrophic out-of-pocket health expenditure.
Results: Catastrophic health expenditure (CHE) with a 40% capacity to pay (CTP) households in the study area was 22.5%. Female household head (AOR = 2.92; 95% CI: 1.44, 5.93) and household with chronic illnesses (AOR = 3.93; 95% CI: 1.78, 9.14) were positively associated with CHE and, while households who had adult household members (AOR = 0.32; 95% CI: 0.16, 0.63) were negatively associated.
Conclusion: The overall CHE, with a 40% CTP threshold, was high. Prevention of chronic illness might help to reduce the burden of the expenditure. Strengthening financial risk protection mechanisms, such as community-based health insurance, could help bring healthcare services equity.

Background

Out-of-pocket (OOP) health expenditure refers to the payments made by households at the point they receive health services,1 and it is the principal payment methods for health care services in developing countries.1–3 Fee for service, capitation, case-based, and global budget- based provider payment mechanisms are other payment mechanisms for health care services.4 Out-of-pocket for healthcare is termed as catastrophic when the total health expenditure equals or exceeds 40% of the total household’s capacity to pay.1,2,5 The household’s capacity to pay (CTP) is the non-subsistence effective household income and the minimum requirement to maintain basic life in society. Households’ ability to pay for health care and the denominator is total household expenditure (or sometimes income), which assumes that all household resources are available for spending on health using the budget share method.1,2,6 A study conducted across 133 countries in 2010 indicated that more than 808 million people incurred catastrophic health expenditure (CHE)7 and 122 million people were pushed into poverty.8 Between 2000 and 2010, CHE incidence increased from 9.7% to 11.7%, proving the lack of financial protection progress.7,8 In low- and middle-income countries, CHE pulverizes households’ income and labor supply.9 It disrupts households’ welfare and pushes them into impoverishment, exacerbates their poverty, and hampers healthcare-seeking behaviors.10–13 It also creates socio-economic and health disparity among households; and compels them to cut spending on necessities, sell assets, and borrow from the wealthiest households; and makes them sink into the poverty trap.14

Studies showed that CHE with a 40% CTP threshold ranged from 4.12–73% [15–19], and CHE concentration among the poor was also high.15–18 Evidence also showed that socio-demographic and economic factors healthcare service and disease-related factors are significantly associated with CHE. These include wealth status, residence, employment and educational status of household head, working conditions of adults, vulnerable and aged members in the household, household size, age, and sex of the household head.12,14,19–21 Healthcare financing in Ethiopia is still dependent on OOP expenditure with low government spending, which may lead to inefficient and inequitable healthcare utilization, and households to be impoverished because of poorly harmonized and unpredictable donors.22 Community-Based Health Insurance (CBHI) schemes and subsidizing some priority interventions’ costs through exemptions22,23 can protect households from financial risks.

However, subsidizing some treatment costs on specific diseases remains unclear, and whether the subsidies have been providing reasonable financial protection to the target households. Previous studies conducted to assess the effect of disease-specific medical costs on household economic status have not well described which illnesses had the highest impact on household expenditures. Health facilities provided a fee waiver for the poorest households, but the health access for a fee waiver has not been adequately addressed because of unclear selection criteria.22

In developing countries, including Ethiopia, the payment mechanism for the healthcare cost is mainly OOP paid at the time of sickness or point of service delivery, which could inhibit healthcare access and lead to impoverishment.24 To curb this problem, the Government of Ethiopia began to implement the Community Based Health Insurance (CBHI) in 2010.25 The CBHI is a non-profit health insurance scheme for the informal sector, formed based on an ethic of mutual aid and the collective pooling of health risks, in which members participate in its management.26 In Ethiopia, the premium for CBHI has been the same (US$ 8.27 per annum) for all households, regardless of economic status.25

As such a flat premium is inequitable, the government is working to introduce a stratified premium based on households’ willingness and ability to pay. However, CBHI was not introduced in the study area at the time of our study, and the households in the district had been paid a fee for service to the health service provider facilities for the services received. A few studies have been done so far; however, the findings did not explain the local context. Therefore, this study aimed to assess the CHE and associated factors among rural households in Mandura district in western Ethiopia.

Materials and Methods

Study Design and Settings

We used a community-based cross-sectional study to assess CHE and associated factors among the Mandura District’s rural households in Benishangul-Gumuz National Regional State (BGNRS) from April May 2017. The district is located in the western part of Ethiopia, and it is 547 kilometers far away from Addis Ababa, the capital city of Ethiopia. It has 20 kebeles (the lowest administrative unit), of which two were urban and 18 rural kebeles. The 2017 Central Statistical Agency (CSA) report indicated that the district had a total population of 55,371 and total households of 12,304.

Population and Sampling Procedures

All households in the selected rural kebeles of Mandura District were the study population. We included all self-reliant households in the selected rural kebeles of Mandura District in the study. However, we excluded new couples who became a household for less than a month during the data collection period from the study.

The sample size was determined using the single population proportion formula with the assumptions of 10.3% proportion (p) of OOPHE in Kenya,27 4% margin of error, design effect of 2, and 10% non-response rate. As a result, the final sample was 488. We used a multistage systematic sampling technique to select the households. In this study, we randomly selected six kebeles from 18 rural kebeles, and the sample size, ie, we proportionally allocated 488 households for each selected kebele. Then, we used the most recent number of households in the district health office to determine the interval and a systematic random sampling technique to select households after a random selection of the first household.

Study Variables

Response Variable

The response variable for this study was CHE. It was categorized into two: Yes if the total health expenditure of a household equals or exceeds 40% of the total household’s capacity to pay, and No if the total health expenditure of a household is below 40% of the total household’s capacity to pay. We collected data on household’s food expenditure; household’s OOP payments for health, including direct health expenditures such as diagnosis and treatment, and health service utilization; and household’s capacity to pay; household’s subsistence expenditure; and equivalent household’s size to estimate CHE.

We assessed the household food expenditure by measuring the amount of money spent on all foodstuffs by the household, plus the values of home-made food consumptions within the household. On some occasions, we measured food expenditure using a day recall period. We used the six-month recall period to assess the cost of clothes’ expenditures to reduce recall bias. Finally, we converted the costs incurred daily for a month by multiplying by 30. However, the costs for alcoholic beverages, tobacco, and food consumption outside the home, such as hotels and restaurants, were excluded from the cost calculation.1 At last, we converted all the expenditures to a monthly figure.

A 30 days’ household OOPHE expenditure was estimated by asking the respondents how much their households had spent for consultation or diagnosis, drugs, other medical supplies, hospitalization, traditional healers, and home remedies. We calculated the household’s capacity to pay by subtracting subsistence expenditure for each household from the household’s total expenditure. We calculated subsistence expenditure for each household by multiplying the equivalent household size by the poverty line. Similarly, the equivalent household size was determined by multiplying the household size by the household scale multiplier (β) = 0.56.1

Explanatory Variables

The study’s explanatory variables were socio-demographic and economic characteristics and health-related characteristics of the participants. These included sex, marital status, ethnicity, educational status, family size, number of children, number of working adults, number of elderly, age and occupation of the head of household, vulnerable members, employment status of head of household, wealth status, perception towards healthcare seeking, type of disabilities, and occurrence of other co-morbidities including in the last 12 months before the actual data collection.28–33

Data Collection Procedures

A structured interviewer-administered questionnaire was developed by reviewing literature.20,21,27 The questionnaire (Appendix 1) was first developed in English and translated to Amharic and back to English to check its consistency. We gave one day of training to data collectors and supervisors on the basic techniques of data collection. The data were collected using six diploma graduated clinical nurses supervised by two BSc graduated clinical nurses and a medical laboratory technologist.

The questionnaire was pre-tested to check for its validity among 24 participants in Gigda Selase kebele. This kebele was excluded from the sample during the actual data collection period to reduce information contamination. We corrected any unclear and ambiguous findings during the pre-testing of the questionnaire. Then, in the final data collection, the data collectors supervised by the supervisors and the principal investigator filled in the questionnaire. All the collected data were checked for completeness, accuracy, and consistency by the supervisors and the principal investigator daily.

Data Management and Analysis

The collected data were entered into Epi Info version 7 and exported to SPSS version 20 for analysis. We used graphs and tables to present descriptive statistics. We fitted a binary logistic regression model and entered variables with a p-value of less than 0.2 in the bivariable logistic regression into multivariable logistic regression analysis. We used a p-value less than 0.05 and Adjusted Odds Ratio (AOR) with 95% CI to identify variables significantly associated with CHE.

Results

Socio-Demographic and Economic Characteristics

A total of 479 household heads participated in the study with a response rate of 98.2%. The study revealed that 84.8% of respondents’ household heads were males, 84.3% were married and lived together with their spouses, 62.8% were Gumuz ethnic groups and 87.5% had no formal education, and 50.5% were Orthodox Christian followers. Ninety percent of the households had at least one <5 children, and 51.1% had more than five family members. About 90% of the households had working adult HH members, and 40.08% were poor. The average HHs size was 5.7 ± (1.99 SD) (Table 1).

Disease and Service-Related Characteristics

The study revealed that 5.4% of the households had a household member with chronic illnesses, and 30.1% had a household member with acute illness and/or injury in the last month. Among those who had a chronic illness or acute and/o injury, 97.6% got medical treatment or counseling services for their illnesses, 75.3% got treatment from a public facility, and 86.1% were treated at the outpatient department. The study also revealed that 96.6% of the participants did not get any subsidies for their treatment cost, and the duration of treatment for 57.8% of the participants was shorter than six days (Table 2).

Distributions and Level of Catastrophic OOP Health Expenditures

The study revealed that 22.5% (95% CI: 19.0, 26.3) of the households had encountered CHE with a 40% capacity to pay threshold. The total average monthly household expenditure in this study was Ethiopian Birr (ETB) 1796± 927.90 ETB (Ethiopian Birr), which was equivalent to 64.88±33.52 US$ (United States of America Dollar). The respondents spent US$ 53.33± 18.49 or ETB 1476.09 ± 511.8 for food and US$ 6.39±22.69 or ETB 177.0 ± 628.0 for their health per household. The study also revealed that the mean subsistence expenditure that the households had spent on maintaining their basic life was US$ 53.76± 11.14 or ETB 1488.0 ± 308.30, and the mean of household’s ability to pay for healthcare services was US$ 15.53± 4.15 or ETB 429.9 ± 115.0 (Table 3).

Factors Associated with Catastrophic Out-of-Pocket Health Expenditures

This study indicated that the sex of the household’s head, the presence of working adults in the household, and having members of the household with any chronic diseases were factors significantly associated with CHE with a 40% capacity to pay threshold. Households which had female household head were 2.92 times (AOR = 2.92; 95% CI: 1.44, 5.93) more likely to encounter CHE compared with male HH heads. Households that had a member of working adults were 68% (AOR = 0.32; 95% CI: 0.16, 0.63) times less likely to face CHE compared to households who had no working adults. Moreover, household members with any chronic illnesses were 3.93 (AOR = 3.93; 95% CI: 1.78, 9.14) times more likely to encounter CHE than their counterparts (Table 4).

Discussion

CHE pulverizes households’ income and labor supply in low and middle-income countries.9 It disrupts households’ welfare and pushes them into impoverishment, and hampers healthcare-seeking behaviors.10–13 The level of CHE with 40% of the capacity to pay (CTP) in the Mandura district was 22.5% (95% CI: 19.0, 26.3). This study finding is consistent with CHE studies conducted in Iran (22.2%) and India (23.4%),30,31 and gastrointestinal cancer patients in Iran (73%).17 This finding was lower than the studies done in China (24.79%) and Kenya (28.3%).32,33 On the other hand, the CHE in this study was higher than studies done in Egypt (6.0%),12 Colombia (9.6%),14 Iran (4.12_17.7%),15–18,34,35 Nepal (13.8%),28 and Tanzania (18%).29 The possible reasons for these differences might be the variability in key preconditions for catastrophic health expenditures since the amount of OOP payments was reliant on the health service utilization.22 The other reason might be most rural dwellers had only hand-to-mouth living standards due to a lack of modern farming systems. As a result, they are economically deteriorated and might have a low capacity to pay for healthcare services. Similarly, the differences in thresholds, socioeconomic status, study participants, period, area and design might also affect the variability of catastrophic OOP health expenditure. Additionally, the practice of early treatment was not practiced in the study area; they usually waiting until the illnesses become severe. This might also affect the OOPHE as a result of the difference in healthcare seeking behavior.

In this study, female-headed households were more likely to face CHE compared with male-headed households. This finding is consistent with studies conducted in China and India.31,36,37 The reason might be due to better educational status, and male household heads’ jobs might enhance households’ capacity to cope with the healthcare costs and reduce households from CHE. On the contrary, this finding is contradicted with the results in India, Egypt, and Korea.12,31,38 The possible reasons might be that most female-headed households might not give too many births than male-headed households. As a result, the household members’ small size might incur less catastrophic OOPHE than larger household members.

Households who had productive adult household members were less likely to encounter catastrophic OOPHE compared with their counterparts. This finding is supported by studies done in Colombian and Kenyan slum communities.14,32 The possible justification might be that households with productive adults were economically better than households with no working adults. As a result, they can afford the cost of any medical expenditure. Furthermore, wealthier households emanated from working adults’ contribution, and they could pay for any medical expenses. Another major factor for catastrophic expenditure was the presence of vulnerable individuals in the household.

The study also indicated that households having a household member with any chronic illnesses were more likely to face CHE. This result is supported by the findings of studies done in Egypt, Tanzania, Cambodia, China, Korea, Iran, and India.12,29,31,35–38 The possible justification might be longer duration, and high treatment frequency might associate with higher medical costs and continuous medical care costs. As a result, this might drive to high healthcare service expenditure. This study’s potential limitation might be the presence of recall bias during the estimation of food and health expenditures by their requested items. Furthermore, seasonal variation of illnesses might cause high variability in CHE. The cross-sectional survey may also over or underestimate health expenditure.

Conclusion

This study revealed that the proportion of households facing catastrophic OOPHE was high. Variables, such as the sex of the household head, working adults, and having members with any chronic illnesses in the households, affected catastrophic OOPHE. Prevention of chronic diseases and introducing financial risk protection mechanisms, such as community-based health insurance, can help bring equity in healthcare services.
