The idea of agency has long been used in the nursing literature in the study of nurses' roles regarding the patients they take care of, but it has not often been used to study its relationship with nurses themselves and their status in the healthcare system. The purpose of this article is to analyze how the idea of agency is used in nursing research to better understand how we might advance our thinking around nurses' agency to shape nursing and healthcare (...) with an emancipatory intent. Based on the results of a literature review focused on the study of conceptions, treatments, and applications of the concept of agency in nursing, we present a critical discussion to reflect on the need to consistently define the idea of nurses' agency, to guide research concerned with this topic in theoretical frameworks with emancipatory and social change tenets, and to make a call to develop the idea of agency as a central one to rework nurses' relationship with themselves. The idea of agency provides a valuable analytical framework for the study of a wide range of issues around nurses' status in healthcare organizations and in the healthcare system while offering a means for nurses' emancipation.
