Agency Nurse Orientation

Hi....I am in staff development at a rapidly expanding 250 bed hospital. I am in charge of nursing department orientation. Besides our new employees, my hospital has recently been hiring a large number of agency nurses. We are on the path to going "paper free", and with the advent of computerized documentation it is near impossible to do a "quick" agency orientation. Our computerized documentation training for new employees runs approximately 6 hours. Would anyone mind sharing what you do for agency orientation? Any thoughts??? We also run into the same issue with student nurses.
