Introduction of a Health Care System Lens-of-Equity Measurement Strategy to Optimize Breast Cancer Screening

Health equity is greatly impacted by the systems and processes with which health systems deliver care. Given the minimal guidance on measurement and reporting of health inequities specific to key population health outcomes, a solution for measurement of health equity is proposed.The concept of a <i>lens of equity</i> was adopted to disaggregate common measures such as breast cancer screening rates to expose inequities across neighborhoods and races in populations served. Two measures were introduced into the corporate measurement systems, race/ethnicity as measured in the electronic health record, and a surrogate measure of family income.An equity category was added to system scorecards and counted toward corporate goals along with data insights and discovery tools to support the efforts of the breast cancer screening improvement teams. Over a 1-year timeframe, Endeavor Health not only met but exceeded its breast cancer screening equity goal, increasing mammography adherence from 73 to 82.6% among residents in the lowest-income neighborhoods served.The analytics and data systems that support complex health care measurement tools require diligent and thoughtful design to meet external reporting requirements and support the internal teams who aim to improve the care of populations served. The analytic approach presented may be readily extended to populations with other potentially impactful differences in social determinants and health status. A "lens-of-equity" tool may be established along similar lines, allowing policy and strategy initiatives to be appropriately targeted and successfully implemented.
