Average Inpatient CM case load?

we have a pilot going in our facility.
3 case managers responsible (insurance reveiw, 6 questions for screen as to what should be refered to sw)
1 case manager associate( gets auth, faxes ,pris, phone calls writes in disharge notes of canopy home care and pri auth information order equipment
nurse RATIO 1:17 1:16
they should do all the requested reveiws and all their news. We would like them to get 1/2 of their reveiws in canopy meeting criteia. this may include the requested reveiws and their news. they also document in the discharge note of canopy. comment greatly appreciated
