An SS medical academy was established in Berlin in 1938 to train Waffen-SS physicians.[312] SS medical personnel did not often provide actual medical care; their primary responsibility was medicalized genocide.[313] At Auschwitz, about three-quarters of new arrivals, including almost all children, women with small children, all the elderly, and all those who appeared on brief and superficial inspection by an SS doctor not to be completely fit were killed within hours of arrival.[314] In their role as Desinfektoren (disinfectors), SS doctors also made selections among existing prisoners as to their fitness to work, and supervised the killing of those deemed unfit.
