Using comparative effectiveness research to remedy health disparities

A Culture-Centered Community-Grounded Approach to Disseminating Health Information among African Americans

This study highlights the role of local communities in creating culturally rooted health information resources based on comparative effectiveness research (CER), depicting the role of culture in creating entry points for building community-grounded communication structures for evidence-based health knowledge. We report the results from running a year-long culture-centered campaign that was carried out among African American communities in two counties, Lake and Marion County, in Indiana addressing basic evidence-based knowledge on four areas of cardiovascular disease (CVD). Campaign effectiveness was tested through an experimental design with post-test knowledge of CER among African Americans in these counties compared to CER knowledge among African Americans in a comparable control county (Allen). Our campaign, based on the principles of the culture-centered approach (CCA), increased community CER knowledge in the experimental communities relative to a community that did not receive the culturally centered health information campaign. The CCA-based campaign developed by community members and distributed through the mass media, community wide channels such as health fairs and church meetings, postcards, and face-to-face interventions explaining the postcards improved CER knowledge in specific areas (ACE-I/ARBs, atrial fibrillation, and renal artery stenosis) in the CCA communities as compared to the control community.

Using community-based participatory research in patient-centered outcomes research to address health disparities in under-represented communities

The emergence of patient-centered outcomes research (PCOR) has created a paradigm shift in the way health outcomes research is designed, conducted and disseminated. While PCOR expands the potential for patients to play a key advisory role in every aspect of the research process, community-based participatory research (CBPR) has long provided this opportunity for engaging communities in research. CBPR is an excellent tool for achieving PCOR goals of improving the health of all people by providing them with evidence-based information for making informed healthcare decisions. We propose ways by which PCOR can effectively use CBPR principles to engage patients in general, and specifically patients from underserved communities. The hope is that this will help to reduce and eventually eliminate health disparities.
