Brief Summary
-----------------
This study will evaluate various performance metrics of emergency department operations after the implementation of computerized physician order entry in an academic emergency department.

Detailed Description
-----------------
The study will be a prospective before-after study comparing various operational and performance metrics before and after the implementation of a computerized physician order entry system in the emergency department. The investigators will collect 6 month before, 6 month after of data along with a 2-4 week washout period. The investigators will also administer a computerized physician order entry survey after the study is completed.
