In my part of the US they've changed the names of a lot of these places from "Urgent Care" to "Walk-in Clinic", which is really what they are: a doctors office you can go to without an appointment for pressing but non-life threatening issues. For point of reference the Emergency Room is where an ambulance would take you if you called for one. If you are in a similar type of life threatening situation and you choose not to call an ambulance but to drive yourself most Americans know they need to go to the ER.
