I don't know why I am chiming in since I know nothing of this. But, I know solo providers who do things similarly so you could do it for multiple doctors.

Do all the triaging up front. One off staff member takes in the faxes and distributes them to the providers via the computers (shortcuts, etc.) The doctor then reads the lab or x-ray and using a sticky note "signs off" and gives directions to his or her nurse. Sticky notes in PDF/Adobe, etc. have names and time stamps so that can be nice.

So, the doctor just reads the lab, comments as to what needs to be done and forwards it again through the computer to his or her MA. The trick is to make your MA a medical student or something high enough so she/he can import the file. License issues sure, but many work around this.
