Computerized provider order entry in the emergency department: pilot evaluation of a return on investment analysis instrument.

The Vanderbilt Center for Better Health conducted a workflow analysis study to determine the benefits of implementing a computerized provider order entry system in the adult Emergency Department. Time savings by role was 1619 hours/year for nurses, 815 for medical receptionist, -95 for attendings, and -100 for residents. Translating time savings into bottom line savings (FTE/overtime reduction, additional charges) resulted in $31,424 in time savings and $40,000 cost savings (paper forms).
