Hospital equity officers have become critical leaders in the effort to address the determinants of health care disparities, including structural racism. In this mixed-methods study, we surveyed a national sample of equity officers and interviewed a subset of respondents to provide additional perspective. About one-half of survey respondents reported at least some obstacles to achieving their health equity objectives, including racist beliefs among people working in their hospitals and health care systems, policies that perpetuate racism, and a lack of staff diversity. To address these challenges, some hospitals are collecting information about instances of racism, reviewing clinical algorithms for evidence of bias, or forming community partnerships. However, in interviews, equity officers pointed out that racism is a public health issue that cannot be adequately addressed solely within the health care system. Given the relative newness of most hospital equity officer positions, our research may be viewed as an early glimpse into the challenges and opportunities of this evolving work.
