The concept of self-care is multidimensional, with many defining elements. This paper describes the origin of this comprehensive concept. It examines the response of the nursing discipline to citizen self-care initiatives and the subsequent effects this response has had on the development of nursing knowledge. The evolution of self-care as a core concept within Canadian health policy is presented; the potential readiness fo citizens to accept self-care as an aspect of healthcare delivery is explored, identifying potential benefits and obstacles. The paper concludes with a proposed self-care approach to healthcare reform in Canada and the subsequent influence this approach may have on the discipline of nursing. The congruency between a self-care healthcare delivery system and the theoretical foundations and perspective of healthcare delivery held by the nursing discipline is discussed. The role nurses might assume in shaping a self-care healthcare delivery system is delineated.
