Access to health services is a major concern across North America and abroad, with particular salience for the residents of rural and remote areas and the health professionals committed to providing services to them. Intrinsic to this discussion is clarification of the phenomenon of access to health services, a concept that remains nebulous and obscure to consumers, health care providers, and policymakers alike. Multiple understandings of access to health services impedes progress in the development of policy, the creation of programs, and the transformation of health services. Considerable discussion of theory concerning access to health services is articulated in public or community health literature and that of other disciplines; however, limited attention to this topic is apparent in nursing literature. This report articulates definitions, dimensions, and frameworks of access to health services from available literature and existing theory. Further, key points are identified and discussed for consideration in nursing research on the term access and implications for practice.
