Although your facility has a state-of-the-art electronic health record (EHR), it lacks specific functionality to address the needs of emergency department (ED) care. In the interest of patient safety and to integrate emergency department activities into the EHR, your team has been tasked to explore the following four options:  

1. implement and integrate a triage system;  
2. incorporate clinical vocabularies in the EHR to support Emergency Department nursing and physician documentation requirements; 
3. implement radio frequency identification (RFID) technology for patient tracking, and
4. interface emergency medical services (EMS) documentation records into the EHR (e.g., paramedic, ambulance documentation).
