I'd take it one step further. It eliminated their need to analyze disease and focused their attention on recognizing symptoms. They learned that they should input those symptoms into Big Pharma supplied software computer which spits out what drugs are needed to treat. This formed the basis for hospital treatment protocols. What's missing is the clinical analysis of the disease with an eye toward curing. No money in curing a disease when the symptoms can be treated with expensive medications for years on end. More money means more and bigger hospitals, more beds, more drugs and more money in a never ending cycle. Instead of doctors we have high paid systems analysts that do as instructed by big pharma.
