The demographic and epidemiological transitions, characterized by an increase in life expectancy and the prevalence of chronic conditions, have led to a crisis in healthcare systems. This crisis is marked by fragmented systems that focus primarily on acute conditions and lack communication between different levels of healthcare. Brazil's healthcare situation is characterized by a triple burden of diseases, including infectious diseases, external causes, and chronic conditions. To address this crisis, the implementation of health care networks is proposed to restore coherence between the triple burden of diseases and the current healthcare system. International literature suggests that health care networks can improve clinical quality, sanitation results, user satisfaction, and reduce healthcare costs. These networks are characterized by a continuous and integrated approach to healthcare, coordinated by primary care, and involve a population-based approach. The concept of health care networks includes elements such as the population, operational structure, and healthcare models. Evidence from various countries indicates that integrated healthcare systems can enhance clinical outcomes, user satisfaction, and cost efficiency. In Brazil, while there are limited experiences and robust evaluations, case studies suggest that health care networks can significantly impact health levels with sustainable costs.The demographic and epidemiological transitions, characterized by an increase in life expectancy and the prevalence of chronic conditions, have led to a crisis in healthcare systems.
