Guidelines for Practice--what are the experts saying?
National Guideline Clearinghouse
http://www.guideline.gov/

There are guidelines out there, but they are scattered all over at various association websites.
Fortunately, the National Guideline Clearinghouse has gathered them into one place, updated regularly and searchable. So the next time you have to revise a policy or look for benchmarks, start with guideline.gov

And as always, if you don't have time to do that, call the Librarian!
