Kevin,MD ( http://www.kevinmd.com/blog/) recently discussed a newday article about medical interpreters:
Many smaller hospitals do not have trained interpreters available. Often family members/friends are pressed into service. This can create problems:
"We had a case where a patient was being treated for a venereal disease and asked the doctor how she could have contracted it. The doctor explained it, but her husband, who was interpreting, told her that she got it from a public toilet," Sala said.
