InterQual is a product of the InterQual division of McKesson, but you can find lots of samples of their decision or criteria flow sheets on line. They have > 3500 customers (hospitals, managed care orgs, etc) so they must be doing something right. These also cover all kinds of case management, such as outpatience cases, when to refer to a specialist, etc. Think of them as consensus statements, which they are in part based on as well as McKesson's medical experts. Just some of what I am uncovering from considering interviewing with them, so I am biased.
