From @oziadias @m_sendhil et al: ‘...bias arises because algorithm predicts health care costs rather than illness, but unequal access to care means that we spend less money caring for Black patients than for White patients.’

Reporting
@washingtonpost by@Carolynyjohnson: 'The problem was caught in an algorithm sold by a leading health services company, called@Optum, to guide care decision-making for millions of people.’ https://www.washingtonpost.com/health/2019/10/24/racial-bias-medical-algorithm-favors-white-patients-over-sicker-black-patients/ …#disparities#biasPrikaži ovu nit -
Furthermore… 'Correcting the bias would more than double number of black patients flagged as at risk of complicated medical needs w/i the health system the researchers studied, & they are already working with
@Optum on a fix.’ [but are they stopping selling it in the meantime?]Prikaži ovu nit - Još 5 drugih odgovora

In a strange way, the study of algorithmic bias is a faster route to fairness than the study of human bias

Highly recommend the Science podcast interviewing
@oziadias - he discusses the company's response to their findings. https://www.sciencemag.org/podcast/worldwide-worm-survey-and-racial-bias-health-care-algorithm …. Also@brianwpowers tweet thread on the article:https://twitter.com/brianwpowers/status/1187448348489461760?s=20 … - Još 1 odgovor
