What’s the process of hospitals adopting new medical practices as new medical information is discovered?

Are there meetings were doctors go over new medical discoveries and choose which ones they trust to implement? Is it purely a cost issue? Are there approval barriers? Thanks!

Every hospital has committees for this. The medical executive committee will discuss things like this and whether to adopt recommendations or policies. This happens infrequently and there is usually a huge discussion about it. 

One month we discussed evidence that people given X before surgery had fewer heart attacks during surgery. The next month we discussed new evidence that people given X had a higher rate of hemorrhage. Therefore no recommendation to give X was made. Surgeons could opt to do either.

I promise you it is more complicated than you think :)
