Shared decision-making for cancer care among racial and ethnic minorities: a systematic review.

To assess decision-making for cancer treatment among racial/ethnic minority patients, we systematically reviewed and synthesized evidence from studies of "shared decision-making," "cancer," and "minority groups," using PubMed, PsycInfo, CINAHL, and EMBASE. We identified significant themes that we compared across studies, refined, and organized into a conceptual model. Five major themes emerged: treatment decision-making, patient factors, family and important others, community, and provider factors. Thematic data overlapped categories, indicating that individuals' preferences for medical decision-making cannot be authentically examined outside the context of family and community. The shared decision-making model should be expanded beyond the traditional patient-physician dyad to include other important stakeholders in the cancer treatment decision process, such as family or community leaders.
