A friend of mine who is a pediatrician told me the following story.
He has a patient who is a little girl with some chronic medical issues. The girl's mother had some legitimate issues with the nursing care that the girl was receiving while hospitalized as an inpatient. Although this was not the pediatrician's fault, the mother apparently laid into him, screaming at him publicly for a good five minutes.
Of course, the girl is still hospitalized and he's the pediatrician on the inpatient service right now. So now he has this awkward situation with the patient's mom. He said that if this girl had been one of his clinic patients and he'd been treated that way, he would have requested she find a new doctor. But since the girl is hospitalized and probably will be for another week or so, he's stuck.
"I just have to suck it up," he told me.
That's a rough situation though. Even though the mom screamed at him, she didn't fire him so he's still allowed to see her daughter. Is there really no alternative to treating a person whose family was verbally abusive to you?
