EPIC or Lawson to Generate Demand?

Wanted to get feedback from those of you using EPIC and Lawson and how inventory is decremented and patient charges are captured.

I've seen a variety of processes leveraged to enter reqs/issues to create demand/decrement inventory throughout surgical areas using EPIC and Infor. Options where the req/issue and patient charge is entered in EPIC and interfaced into Infor using IC500 and options where a req is entered in Infor and the patient charge is entered separately in EPIC. The challenge with entering in EPIC is if goods need to be returned if they are not used and the challenge with entering in Infor is automating the patient charge.

What are you doing? Trying to finalize some best practice models to make the decrement of inventory and patient charge process is a automated as possible.
