INTRODUCTION: Chronic Kidney Disease (CKD) is a major public health problem worldwide. In Chile, the prevalence of the disease is expected to increase due to the aging of the population and the high prevalence of its risk factors. Moreover, the economic burden of CKD contributes significantly to the overall healthcare spending in the country. OBJECTIVES: To estimate the economic and health consequences of CKD in the Chilean population older than 60 years old, up to the year 2030 from the perspective of Chilean public health system. METHODS: An economic model based on future estimates of population older than 60 years old, prevalence of disease for this group of age, progression of CKD, mortality, and total costs for this population were made using a stock & flow modelling framework. The model was built using Stella Architect®. Key parameters of the model were current cases of CKD which were extracted from the Chilean National Health survey 2016-2017 and progression rates of the disease, estimates simulated based on international evidence. A potential introduction of an intensive medical treatment was simulated in order to estimate the reduction in the progression of the disease and expected cost per year for the Chilean health system. RESULTS: By the year 2030, there is an expected increase in the number of prevalent patients in end stage renal disease of 30,000 people. The expected increase in total cost of all CKD stages US529 million per year. An early intensive intervention is expected to avoid costs around US45 million per year. CONCLUSIONS: The estimates in this study show an important increase in the costs of CKD. This model can be a useful tool for the development of preventive or treatment plans, such as the intensive medical treatment, reducing and delaying the progression of the disease.
