Non-Contributory Health Insurance and Catastrophic Health Expenditure: A Structured Review of Financial Risk Protection in Nigeria
This structured review examines evidence from Asia, sub-Saharan Africa, and Nigeria to conclude that while non-contributory health insurance schemes improve healthcare utilization, their impact on reducing catastrophic health expenditure is mixed and heavily dependent on scheme design, funding predictability, and facility capacity.

Imagine a family in a low-income country facing a sudden illness. In many places, there is no safety net to catch them when they fall. Instead of a bill being covered by an insurance plan or the government, the family must pay for every pill, every bandage, and every doctor's visit directly from their own pocket. When these costs become too high, they are forced to stop buying food, selling their livestock, or pulling their children out of school just to survive the medical crisis. This moment, when a medical bill threatens to destroy a family's financial stability, is known as catastrophic health expenditure. For decades, the global goal has been to build systems that prevent this, often by creating health insurance schemes where the poorest people do not have to pay a monthly fee to join. The idea is simple: if you remove the price tag at the hospital door, the poor will get care, and they will not be ruined by the cost. But does this simple promise actually hold up in the real world?
A team of researchers from Nasarawa State University in Nigeria set out to find the answer by looking closely at the actual evidence from around the globe. They did not just read headlines or policy documents; they dug into the hard data from studies conducted in countries like Vietnam, China, Ghana, Tanzania, Kenya, and Nigeria. Their goal was to separate what happens when people sign up for these free or subsidized insurance plans from what happens to their bank accounts. They wanted to know if the act of getting insurance truly stops families from falling into poverty when they get sick, or if the reality is more complicated than the policy makers hope.
The researchers found that the first part of the promise works very well. When governments or donors set up these non-contributory insurance schemes, people do start going to the doctor more often. The studies showed a clear pattern: once the financial barrier of a direct fee is removed, families who were previously afraid to seek help begin visiting clinics and hospitals. They stop relying on untrained street vendors for medicine and start using formal health facilities. This shift in behavior is consistent across every country examined, from the rural villages of Vietnam to the states of Nigeria. The insurance successfully gets people through the door.
However, the second part of the promise—the protection from financial ruin—is far less certain. The researchers discovered that simply getting people into the system does not automatically stop them from spending a dangerous amount of their money on health. In some cases, the insurance did not lower the total amount families spent at all. In China, for instance, one major study found that while insurance encouraged people to use more medical services, it actually led to an increase in overall spending for those who were already better off, while the poorest families saw no change in their financial burden. The poorest households, who needed protection the most, often still faced costs they could not afford, such as transport fees, accommodation while traveling to a hospital, or hidden charges that the insurance did not cover.
The picture becomes even more nuanced when looking at where people go for care. In Nigeria, a specific study in Ekiti State revealed that the type of hospital a person visits matters just as much as whether they have insurance. Families using private facilities were twice as likely to face catastrophic costs compared to those using public facilities, even within the same state. This suggests that the design of the insurance plan is not enough; the quality and funding of the hospitals themselves are critical. If the local clinic runs out of medicine or if the government is slow to send the money needed to pay the staff, the insurance card becomes useless, and the family is left paying out of pocket again. The researchers noted that in some Nigerian states, funds meant to support these schemes were delayed or never arrived, leaving the system broken before it could even help anyone.
The review also highlighted that measuring success is tricky. How researchers define a "catastrophic" bill can change the results entirely. If a study counts a bill as catastrophic when it takes up ten percent of a family's income, the number of affected families looks high. If the definition is changed to twenty-five percent, the number drops dramatically. This means that some reports claiming success might just be using a different ruler to measure the same problem. The researchers emphasized that counting how many people have insurance cards is not the same as measuring how safe those people are financially.
Ultimately, the study concludes that while these insurance schemes are powerful tools for getting people to seek care, they are not a magic wand that instantly solves the problem of medical poverty. The path from having a health card to being truly protected from financial disaster is not a straight line. It depends on whether the hospitals have the resources to treat patients, whether the government pays its bills on time, and whether the insurance covers the hidden costs of getting to the hospital. The researchers argue that policymakers should stop assuming that enrollment numbers equal financial safety. Instead, they must look deeper at the specific details of how the money flows and where the patients actually go. Until these gaps are fixed, the promise of universal health coverage will remain only half-fulfilled, leaving the most vulnerable families exposed to the very risks the system was designed to prevent.
