Healthcare networks are essential to address the challenges posed by an aging population and the increasing prevalence of chronic diseases. Brazil faces a triple burden of diseases, including infectious diseases, external causes, and chronic conditions. Current healthcare systems are fragmented and focused on acute care, leading to inefficiencies in managing chronic conditions. The solution lies in implementing healthcare networks, which integrate different levels of care to provide continuous, coordinated, and quality-focused services. Evidence from international literature suggests that healthcare networks can improve clinical quality, sanitation outcomes, user satisfaction, and reduce healthcare costs. The Brazilian healthcare system needs to adapt to the demographic and epidemiological transition by restructuring to address the growing prevalence of chronic diseases. This involves creating integrated systems that prioritize chronic care, ensure continuity of care, and promote health equity. Healthcare networks are defined as structured systems that coordinate care across different levels, emphasizing primary care as the central point of coordination. These networks aim to provide comprehensive, continuous, and integrated care, addressing the complex needs of populations with multiple health conditions. The implementation of healthcare networks is crucial for improving the effectiveness and efficiency of healthcare systems in Brazil and globally.Healthcare networks are essential to address the challenges posed by an aging population and the increasing prevalence of chronic diseases.
