The internationally accepted definition of PHC is qualitatively different from that of PC. Both PC, which produces professionally and institutionally driven services, and PHC, which creates community-based and community-driven services, can serve Nursing's Agenda for Health Care Reform.

Although economic impoverishment has long been recognized as a health risk, it has not generally been targeted as a modifiable risk factor. A number of methodologic and conceptual issues have impeded and obscured explanation of the nature and characteristics of the relationship between socioeconomic status and health. Further investigation is needed to address directional effects, confounding factors, and measurement difficulties. Conceptual representations of the links between economic impoverishment and health need to be clarified and expanded. Until this relationship is better understood, development of effective strategies to improve health for the economically disadvantaged will be problematic.

Researcher/participant matching has been used in nursing research as a strategy for the development of culturally competent knowledge. In this manuscript, the complexities inherent in matching in nursing research are discussed. In raising and discussing issues and questions related to matching, we argue that although matching may be one of the strategies used to generate culturally competent knowledge, it is frequently too complex for operationalization. Therefore, we propose that researchers reflect on questions related to their knowledge of culture, their cultural sensitivity, and the nature of collaboration during every phase of the research. Reflecting on and responding to these questions in every research project may facilitate the development of more culturally competent knowledge.
