Chronic kidney disease is one of the leading public health problems in the world. Approximately one out of 10 adults have some form of kidney disease. Mortality rate from cardiovascular disease at all stages of chronic kidney disease is very high. Early identification and appropriate treatment may slow down progression of chronic kidney disease. Therefore, it is important to raise awareness of the presence of kidney disease in population, both among potential patients and among physicians. Research goals of thesis included estimation of value of the written material for their education (eg., health and educational manual "Chronic kidney disease"), as well as to determine whether patients of different age, formal education, and duration of disease understand content of the health-educational materials, whether and how it helps in understanding and acceptance of their disease and better treatment. The study was conducted in 80 patients with chronic kidney disease (stage severity of illness was I to IV). Both genders were equally represented. The age range of patients was 25 to 89 years. The average age was 62 years. According to the formal education patients were divided into 4 groups: primary, secondary, higher and university grade education. Younger and better educated patients have read the entire manual and understood its contents. The differences compared to older participants were statistically significant. Most patients (91.3%) expressed opinion that this manual meets their needs for knowledge, isn’t verbose and helped them to better understand and treat their illnesses. According to our results patients with chronic kidney disease have to learn a lot about their illness in order to be able to actively participate in decisions regarding the treatment. Good education encourages patient compliance, thereby contributing to the reduction of complications and better treatment success. Manuals printed as health education materials are indispensable element in the training and have demonstrated exceptional value.
