Elucidating the role of place in health care disparities: the example of racial/ethnic residential segregation.

To develop a conceptual framework for investigating the role of racial/ethnic residential segregation on health care disparities. Review of the MEDLINE and the Web of Science databases for articles published from 1998 to 2011. The extant research was evaluated to describe mechanisms that shape health care access, utilization, and quality of preventive, diagnostic, therapeutic, and end-of-life services across the life course. The framework describes the influence of racial/ethnic segregation operating through neighborhood-, health care system-, provider-, and individual-level factors. Conceptual and methodological issues arising from limitations of the research and complex relationships between various levels were identified. Increasing evidence indicates that racial/ethnic residential segregation is a key factor driving place-based health care inequalities. Closer attention to address research gaps has implications for advancing and strengthening the literature to better inform effective interventions and policy-based solutions. © Health Research and Educational Trust.
