ER physicians (the smart ones,at least) practice defensive medicine more vigorously than any other specialty.
Unfortunately, she does have a legitamate complaint. It is standard of care in my area to scan “drunk with head bonk.” Not defensive medicine or CYA, simply SOC. I’m sure she got a nice check.
Unfortunately, stupid sometimes pays and I’m certain she did not learn a lesson. In my experience the learning-from-bad-experience neuron is turned off when drunk.
