Hi! I'd suggest that you call a few travel agencies and ask them where their top demand is. Recently I did this because I am thinking about traveling in the future but have been in a clinic setting. I need to get back into an acute care setting for a year or so first. The top needs of the agencies I polled were (in descending order) ICU, CCU, Telemetry, ER, Med-Surg. Katieglo
