Race is too important in medicine to merely be a social construct. Different races have significantly different disease rates (incidence rates), such that you cannot erase them even if you control for environment (born in the same city, at the same time, went to the same school, etc). If you were to open a large hospital in town X, you would very much want to know X's demographic structure to make informed decisions on how many highly specialized professionals and equipment you would need to effectively treat the population. Making design mistakes at this stage would literally cost lives.
