Sometimes this new knowledge substantiates traditional care, and sometimes it offers alternatives and improvements. In either case, today's physician is faced with an overwhelming amount of scientific knowledge. Relatively few patients know their doctors well, at least in the USA, and the converse is true as well. As patients and doctors become socially distanced, there is less interest in treating the social side of problems. Instead, care is compartmentalized, specialized, and distanced.
Science is used as the excuse for insensitivity.
All of this white coat veneer gives science a bad name. Comfort is just as important as surgical skill, and science can be practiced with humanity. This problem certainly isn't unique to medicine. My local automobile dealership doesn't have mechanics who listen to the problem, think about likely causes, and then repair the car. Likewise, doctors are being asked to see more patients each hour, order fewer tests, and generally do more with less.
