You need actual data on the incidence of medical conditions and risk factors
If you start allocating and recommending treatment based on past treatment of, let's say, the African-American population, then you are begging for inaccuracies in the future. African-Americans may have received fewer medical appointments and procedures, due to racial animus against treating them, lack of doctors in areas with larger African-American populations, based on lower African-American incomes and employment restricting access to medical services and due to African-American populations being anxious about seeking help from the largely white medical profession.
So if you bake all that biased past data into current coverage models, then you can definitely carry forward past racial and racist disparities.
