Say you're a Midwestern farmer in a hospital bed, recovering from surgery or a major illness. It's time for the nurse's check-in, but there's no knock on the door.
At Mercy Hospital in St. Louis, a camera attached to the wall over the foot of the bed whirls around, as a video monitor next to the camera lights up to show a smiling face with a headset on.
"Good afternoon, this is Jeff with SafeWatch," the smiling face says. "Just doing my afternoon rounds."
