Unequal access to high-quality health care is a key contributor to health disparities. Data is a critical piece of eliminating these inequities; it can allow providers to recognize gaps that exist, identify where improvements are needed, and enable payers to reward providers that can reduce or eliminate disparities. Under a previous grant from the foundation, Yale’s Center for Outcomes Research and Evaluation (CORE) developed an approach to measuring health care quality disparities based on race and ethnicity. This funding will support the next phase of this work, including additional validation to ensure providers have faith in the methodology, and work to strengthen the case for incorporating health equity quality metrics into health care delivery to reduce racial and ethnic health disparities.
