Introduction: The use of race in estimation of glomerular filtration rate (eGFR) started a critical national conversation on numerous areas of medicine touched by racism; with a call for removal of race from calculation of eGFR. We scrutinized use of "Black race" coefficient in Modification of Diet in Renal Disease (MDRD) eGFR calculation and consequence of its use on our local community in SW Michigan.
Methods: A cross-sectional analysis of de-identified electronic health record data from routine outpatient primary care visits, from January 1, 2019, to December 31, 2019, included variables such as age, race, gender, serum creatinine levels, and calculated eGFRs (if any), using χ2 tests for association and Wald-approximation 95% confidence interval.
