How effects of racism were mistaken for “race” in clinical algorithms: What clinicians should know

For years, when physicians order tests to assess lung function, or blood work to determine kidney function, or look up guidelines for managing high blood pressure the results have been adjusted for race. This practice has been based on studies that seemed to indicate that the same result means different things if the patient is Black vs white. So, for instance, an “uncorrected’ creatinine of 1.6 was thought to be less concerning in a Black than white patient as Blacks were thought to have greater muscle mass (not true). These correction factors masked underlying environmental and social stressors disproportionately affecting Black Americans. Regrettably they also contributed to delays in care for chronic conditions, as Black patients had to be sicker than white patients to trigger therapeutic interventions – further exacerbating disparities. We talk with two physicians who lead an anti-racism equity committee based in a Chicago VA hospital to understand the history and science that led to these “corrections,” and how they have successfully been removing them through education and advocacy across their organization and nationally. Their activism is especially meaningful because of its immediate, tangible, benefit for affected patients.
