April, 2017 - SUPPORT Summary of a systematic review | print this article |
People with low incomes often have poor access to health services and limited ability to pay for medical care. For such individuals and households, substantial out-of-pocket healthcare expenditure may have catastrophic financial consequences and worsen poverty. Health insurance schemes are intended to reduce the burden of health costs on individuals and households.
For many people in low-income countries, poverty may both reduce access to healthcare and be worsened by large out-of-pocket payments for healthcare. Poor people include individuals working in the formal sector with low salaries and most of those employed in the informal sector.
Health insurance is a method of reducing the difficulties related to paying for healthcare. The intended impacts of health insurance include improvements in healthcare coverage and health status and reductions in out-of-pocket payments for individuals and households.
Social health insurance (SHI) involves compulsory contributions levied largely on the earnings of formal sector workers and the payment of healthcare providers through an independent mechanism (a health care purchaser).
Community-based health insurance (CHI) are not-for-profit schemes based on voluntary enrolment in which a community (which may be geographic, religious, professional or ethnic) is actively engaged in mobilizing, pooling, and allocating resources for healthcare.
|Review objectives: To systematically examine studies that show the impact of nationally or sub-nationally sponsored health insurance schemes on the poor and near poor.|
|Type of||What the review authors searched for||What the review authors found|
|Study designs & interventions||Randomised trials, non-randomised trials, controlled before-after studies, regression studies and qualitative studies that measured the impact of national health insurance.
||24 studies were included: 4 randomised trials, 10 non-randomised trials and 10 observational studies. 16 studies reported on SHI and 3 on CHI. 19 studies strongly met the review inclusion criteria and 5 partially met the inclusion criteria.|
|Participants||People taking up health insurance.
||People who enrolled in social and community health insurance schemes.
|Settings||Low- and middle-income countries
||Burkina Faso, China (6 studies), Colombia (2 studies), Costa Rica, Egypt, Georgia, India (2 studies), Mexico (3 studies), Nicaragua, Philippines, Tanzania and Vietnam (3 studies). One study was done in Senegal, Mali and Ghana.
|Outcomes||Access or utilisation, healthcare expenditure and health status.
||Access or utilisation, healthcare expenditure and health status.
|Date of most recent search: July 2010|
|Limitations: This is a well-conducted systematic review. However, the methods for assessing the risk of bias of the included studies were unclear.|

The review included 24 studies, conducted in low- and middle-income countries. The review did not report quantitative data and therefore the results are reported narratively.
Twenty studies reported on this comparison.
Social health insurance comparaded to no insurance
|People: Poor people including those working in the informal sector
Settings: Low- and middle-income countries (Nicaragua, Mexico, Colombia, Georgia, Ghana, China, Vietnam, Egypt, Indonesia)
Intervention: Social health insurance
Comparison: No health insurance
|Outcomes||Impact||Certainty of the evidence
|Utilisation of health services (use of different types of health facilities including public and private; use of specific health services like diabetes care or prenatal care; visits to physicians; outpatient / inpatient services; use of formal / traditional medicine)||14 studies reported this outcome. Eight studies reported higher utilisation of health services and 5 studies found no increased utilisation among the insured.
|Out-of-pocket expenditure on healthcare services
||14 studies reported this outcome. Seven studies found reduced OOP expenditure among insured participants; 6 studies found little or no changes in expenditure; and 1 study found an increase in expenditure.||Very Low
|Health outcomes (e.g. glucose control in diabetic patients, infant mortality and health status of communities)||Five studies reported this outcome. Three studies found little or no improvement in health outcomes for the insured and 2 studies found improvements in health outcomes.||Very low|
|Equity||Some studies assessed impacts on poorer groups and found mixed results for utilisation of services and out-of-pocket expenditure.||Very Low|
|GRADE: GRADE Working Group grades of evidence (see above and last page)|
These were community-based health insurance programmes, some of which were initiated by the government
of the countries.
Community health insurance compared to no insurance
|People: Poor people including those in the informal sector
Settings: Low- and middle- income countries (Burkina Faso, China and India)
Intervention: Community health insurance
Comparison: No health insurance
|Outcomes||Impact||Quality of the evidence
|Utilisation of health services (use of different types of health facilities including public and private; use of specific health services like diabetes care or pre-natal care; visits to physicians; outpatient / inpatient services; use of formal / traditional medicine)
||All three studies that reported this outcome found higher utilisation of health services among those enrolled in community health insurance schemes.
|Out-of-pocket expenditure on health services||Two studies measured this outcome. A decrease in OOP expenditure was reported for one study while the results of the other study were seen as not valid due to a small sample size.||Very Low|
|Health outcomes (e.g., glucose control in diabetic patients, infant mortality and health status of communities)||One study reported improvements in health outcomes.||Very Low|
|GRADE: GRADE Working Group grades of evidence (see above and last page)
