This is a theoretical-reflective study, with the objective of discussing the concepts of continuity and coordination of care, its conceptual interface and nurses’ actions for its effectiveness in health services, based on international and national scientific publications. The concepts have been studied for decades and, although they are interrelated, they are used in a similar way, indicating a lack of conceptual understanding. The concept of continuity underwent paradigm shifts and began to adopt patients’ perspectives. Currently, it involves interpersonal, longitudinal, management and informational domains. Coordination consists of establishing connections between the possible elements involved in care. It is classified as horizontal and vertical and is organized into categories: sequential, parallel and indirect. Nurses stand out through actions aimed at coordination and continuity at different levels of care, which contributes to strengthening a cohesive and people-centered care. The interface between concepts indicates that, in order to achieve integrated and continuous services, continuity and coordination of care need to be interconnected and act together.
