An estimated one million black adults would be transferred earlier for kidney disease if US health systems removed a ‘race-based correction factor’ from an algorithm they use to diagnose people and decide whether to administer medication. There is a debate surrounding whether or not race-based correction should be removed, on the one hand, it perpetuates the problematic idea that people of different ethnicities have different biology, but on the other hand it’s not actually clear whether or not its removal would help or hurt the health of those one million black adults. The article upon assessing this correction factor examines how it might be corrected.
