When our ambulance service was hospital bases, we used paramedics in our triage. It has worked well. They helped ED out in their downtime this way. I took my children in several times, and was very happy with how well they triaged real emergencies from the misc ear aches, sprains etc. I took children in for things from airway issues due to allergic reactions to non-emergent sprains. The paramedics got it right every time.
