My lede:

Nurse practitioners and physician assistants account for at least 10% of outpatient visits and increasingly are being used to handle patient care in emergency departments, according to previous research.

But a new survey said 80% of patients expect to see a physician when they come to the ED. Fewer than half would be willing to see an NP or PA for an ankle injury — they would rather wait two more hours to be cared for by a physician.

The whole shebang.
