Along with changes of medical model, hospitals need to provide best outcome with lowest cost and best patient′s experience rather than merely medical treatments. It is the cultivation of lean awareness to the doctors that could acquire such outcome. The healthcare lean awareness can be summarized as responsibility awareness, digitalized awareness, detail awareness, and outstanding awareness. Through the cultivation of lean awareness, humanism can immerse into the doctors′practice, which is conducive to train for the great masters of the medicine.
