Chronic kidney disease – a major public health problem

Abstract

Introduction. Chronic kidney disease (CKD) is a major and growing global public health problem, contributing to significant morbidity, mortality, and financial strain on healthcare systems. Despite available preventive measures, CKD often remains underdiagnosed and insufficiently addressed by health policies worldwide.

Materials and methods. A literature review was conducted using the MEDLINE electronic database via PubMed, Scopus, and the HINARI (Research4Life) program, focusing on studies published since 2001. Search terms included “primary care”, “chronic kidney disease”, “chronic kidney disease public health”, and “chronic kidney disease costs”. Original articles, meta-analyses, and systematic reviews were included, with English-language articles prioritized. Bibliographic references of selected publications were also examined to identify additional relevant studies.

Results. CKD affects approximately 700-850 million people globally, with rising prevalence and mortality rates, especially in low- and middle-income countries. The disease disproportionately burdens vulnerable populations and health systems due to high direct and indirect costs, particularly for advanced-stage care. While cost-effective prevention and early detection strategies are available, their implementation is uneven, and policy responses have historically lagged. Successful national initiatives demonstrate that early intervention and integrated care can reduce the incidence and economic impact of end-stage kidney disease.

Conclusions. CKD is a preventable, yet increasingly prevalent disease that requires urgent public health action. Prioritizing early detection, integrated care models, and policy reforms can significantly curb its global burden. Coordinated efforts at international, national, and local levels are essential to translate existing knowledge into effective practice and reduce the societal and financial costs of CKD.
