Multidomain chronic kidney disease knowledge and associated factors among adults attending a nephrology clinic in Nigeria: identifying gaps for patient intervention to improve outcomes
This study of 304 adults at a Nigerian nephrology clinic reveals that overall and domain-specific chronic kidney disease knowledge is critically low, with only 8.8% of patients demonstrating adequate understanding, and identifies higher educational attainment as the sole independent predictor of better knowledge, underscoring the urgent need for structured, literacy-sensitive patient education to improve health outcomes.

Chronic kidney disease is a condition where the body's internal filters, the kidneys, slowly lose their ability to clean the blood and remove waste. Over time, this failure leads to a buildup of toxins that can damage the heart, bones, and nerves. For patients living with this condition, knowing how the disease works is not just helpful; it is a vital tool for survival. Understanding what causes the illness, recognizing the warning signs, and knowing which tests track its progress allows a person to manage their health effectively. Without this knowledge, patients may miss critical steps in their treatment, leading to faster disease progression and a lower quality of life. In many parts of the world, especially in regions with fewer medical resources, patients often struggle to get clear, consistent information about their condition, leaving them to navigate complex medical advice on their own.
In a recent study conducted at a major teaching hospital in Lagos, Nigeria, researchers set out to measure exactly how much adults with chronic kidney disease understood about their own condition. The team, led by Williams Braimoh Rotimi and colleagues, invited 304 patients who were already receiving specialist care to answer a series of questions. These questions covered five specific areas: general facts about the disease, how the kidneys actually work, the symptoms that signal trouble, the risk factors that can cause the disease, and the medical tests used to diagnose it. The researchers wanted to see if simply visiting a specialist clinic was enough to ensure patients were well-informed, or if significant gaps in understanding remained even among those under professional care.
The results revealed a stark reality. Despite being under the care of kidney specialists, the average patient in this group knew less than half of what they needed to know. When the researchers calculated the total score for all participants, the average knowledge level was just 36.8 percent. This means that for every ten facts a patient should know about their disease, they were only getting about four right. Only a tiny fraction of the group, fewer than nine out of every hundred people, demonstrated a good level of understanding. The study broke down the knowledge into its specific parts to see where the confusion lay. Patients were most familiar with the tests doctors use to check their health, such as blood and urine tests, where they scored nearly 48 percent. They also had a decent grasp of the symptoms, scoring around 44 percent. However, their understanding of how the kidneys function and what factors put them at risk was much weaker. Knowledge of kidney function was the lowest of all, with an average score of just 28.9 percent, and understanding of risk factors was only slightly better at 31.7 percent.
The researchers looked closely at the people in the study to see if age, gender, income, or how long they had been sick made a difference in what they knew. They found that none of these factors were the deciding element. A patient's age, their job, their monthly income, or how severe their kidney disease was did not independently predict whether they had good knowledge. The only factor that stood out clearly was education. People who had attended university or college were significantly more likely to understand their condition than those with only primary or secondary schooling, or no formal education at all. Even among patients who had been seeing a specialist for years, those with less formal education struggled to grasp the core concepts of their disease.
This pattern suggests that the way medical information is currently delivered in these clinics is not reaching everyone equally. The study indicates that simply being present in a specialist clinic does not guarantee that a patient will learn how to manage their kidney disease. The gaps in knowledge, particularly regarding how the kidneys work and what causes them to fail, are dangerous because they prevent patients from making informed choices about their diet, medication, and lifestyle. The authors conclude that to improve health outcomes, doctors and nurses need to integrate structured, easy-to-understand education into every visit. This education must be sensitive to the patient's level of literacy, ensuring that complex medical ideas are explained in plain language that anyone can grasp, regardless of their educational background. Without this targeted approach, the cycle of poor understanding and poor health outcomes is likely to continue.
