Toward a new definition of health disparity: a concept analysis.

In response to federal requests for investigation into measures to eradicate health disparities, a concept analysis of the term health disparity was conducted. Health-related and multidisciplinary literature was reviewed. Multiple terms were explored alone and in combination with no limitations on search date parameters. Findings indicated several definitions of the concept,with the term health care disparity being used interchangeably with the term health disparity. New theoretical and operational definitions, antecedents, characteristics, and consequences of the concept are proffered. Model, borderline, and contrary cases are developed to illustrate the concept. Nursing implications and recommendations for future research are discussed.
