**Introduction**: Population aging drives the development of home care practices, expanding the role of healthcare teams. The Home Care Service (SAD) is characterized by comprehensive actions in health promotion, prevention, treatment, and rehabilitation performed at home, ensuring continuity of care and effective integration with healthcare networks and the user. **Objective**: To highlight the relationship between the Home Care Service (SAD) and healthcare networks. **Methodology**: This is a descriptive study in the form of a narrative literature review, which sought to highlight the relationship between the Home Care Service (SAD) and healthcare networks. The research was conducted through online access to the PubMed, Medline, and Scielo databases, using the descriptors "home care services," "SUS," and "healthcare networks." Inclusion criteria were: articles available in full text, in Portuguese and English, addressing the topic, and published between 2019 and 2023. **Results**: The results highlight the importance of home care services in assessing, identifying, and training caregivers, promoting self-care and user autonomy. The lack of professional guidance for caregivers presents an opportunity for improvement in care practices. Furthermore, SAD stands out as an innovative strategy in healthcare, surpassing primary care and emergency services, adopting a humanized approach aligned with SUS. By replacing or complementing hospital stays, it seeks equity in resource distribution for efficient access to home care, with active intervention in caregiver training, playing a crucial role in preventing complications, and consolidating itself as a key agent for a patient-centered approach within the SUS framework. **Conclusion**: The intervention of SAD with the user and caregiver is of utmost importance in training caregivers to assist users, avoiding unnecessary complications and ensuring continuity of care within SUS. Thus, the service complements the care provided in primary care and emergency services and substitutes or complements hospital stays.
