When Healthcare Breaks the Bank: Catastrophic Healthcare Expenditure and Impoverishment Among Chronic Disease Patients Across Public Healthcare Facility Tiers in Lagos, Nigeria
This study of chronic disease patients in Lagos, Nigeria, reveals that out-of-pocket healthcare costs frequently lead to catastrophic expenditure and impoverishment, with financial burdens escalating significantly at higher-tier public facilities and being strongly mitigated by health insurance coverage.

For millions of people around the world, managing a long-term illness like high blood pressure or diabetes is a constant balancing act. It is not just about taking medicine; it is about paying for it. In many places, especially where health insurance is rare, families must pay for every doctor visit, every pill, and every test directly from their own pockets. This system creates a dangerous financial trap known as catastrophic health expenditure. This happens when the cost of medical care becomes so high that it consumes a dangerous portion of a family's income, leaving them with nothing left for food, rent, or other basic needs. When this spending pushes a family that was previously doing okay into poverty, it is called impoverishment. Understanding how these costs build up is critical because it reveals whether a health system is protecting its people or breaking them.
A team of researchers set out to measure exactly how severe this financial burden is for patients with chronic diseases in Lagos, Nigeria. They focused on the public healthcare system, which serves the majority of the population, and looked at how costs change as patients move through different levels of care. The study examined 480 adults receiving treatment for long-term conditions across six public hospitals, ranging from small community clinics to large, specialized teaching hospitals. The researchers asked detailed questions about the patients' lives, their household income, and every single expense they incurred for their health, from the price of medication to the cost of transportation to the clinic. They wanted to see if the type of facility a patient visited made a difference in whether their family would face financial ruin.
The results paint a stark picture of economic strain. Before they even began paying for treatment, the median monthly income for these households was already low, sitting at 250,000 Nigerian Naira. Once the illness struck, that income dropped to 200,000 Naira, showing that the disease itself had already eroded their financial stability. When the researchers looked at the actual cost of care, they found a dramatic increase as patients moved up the ladder of medical facilities. A patient visiting a primary care clinic spent a median of 21,800 Naira per month. For those at secondary hospitals, the cost rose to 37,000 Naira. But for patients at the tertiary, or highest-level, hospitals, the monthly bill skyrocketed to 95,500 Naira. The main drivers of these costs were not the doctor's fees, but the price of medicines and diagnostic tests. These expenses dominated the budgets of families at every level, but they were particularly crushing for those seeking specialized care.
The study defined "catastrophic" spending in two ways to ensure the findings were robust. First, they looked at whether health costs took up more than 10 percent of a family's total income. Under this measure, 68 percent of all patients in the study were experiencing catastrophic spending. The second measure looked at whether health costs ate up more than 40 percent of the money a family had left after buying food. By this stricter standard, 66 percent of patients were still in the red. The pattern was clear: the higher the level of care, the higher the risk. While just over half of the patients at primary clinics faced catastrophic spending, nearly 94 percent of those at tertiary hospitals did. This suggests that the very act of seeking more advanced medical help, while often necessary for survival, pushes families deeper into financial crisis.
Perhaps the most sobering finding was about poverty. The researchers found that the vast majority of these patients were already living in poverty before they even paid a single cent for their medical care. About 80 percent of the households were already below the international poverty line before their health expenses were deducted. Because so many families were already so poor, the act of paying for healthcare did not significantly change the number of families classified as "poor" in a statistical sense; they were already there. Instead, the healthcare costs acted as a heavy weight on families that were already struggling to survive. The study showed that older age and having a larger family were the main factors that predicted whether a household would be impoverished, rather than the type of hospital they visited. This indicates that the financial danger comes from a combination of deep-seated poverty and the relentless cost of treating chronic illness.
The researchers also discovered that having health insurance offered a real shield against financial disaster. Patients who were insured were significantly less likely to face catastrophic spending compared to those who were not. However, the study noted that insurance coverage was extremely low, with only about 14 percent of the participants having any form of health plan. This leaves the vast majority of patients exposed to the full force of out-of-pocket costs. The study concludes that the current system is failing to protect the most vulnerable. The financial burden is not just an occasional hardship; it is a structural feature of how chronic disease is managed in this setting. To fix this, the authors suggest that simply expanding access to hospitals is not enough. Instead, there must be a concerted effort to expand insurance coverage, subsidize the cost of essential medicines and tests, and find ways to make the purchasing of these goods more efficient. Without these changes, the path to better health for chronic disease patients in Lagos remains paved with financial ruin.
