I advise against the use of ties. I've seen more than one occasion where the tie was used as a weapon. The patient squeezed the tie, choking the doctor.
On one occasion, even after the patient was separated from the doctor, the tie could not be loosened, and the doctor was suffocating as a result of reduced blood flow to his head. The staff had to quickly cut his $100 tie using scissors.
An attending once in the psychiatry crisis center where I did residency had a policy that he wanted no medical student or resident wearing a tie. Made sense to me. The crisis center was the place where patients were most likely to be acutely dangerous. There was little room in that center.
On the inpatient unit, we were not told we had to wear ties, but were encouraged to look professional. I wore ties on that unit, but whenever there was a code, I immediately took my tie off and put it in one of the drawers in the nurse's station.
I hope the programs that force residents to wear ties are very aware of this problem. If they still make the residents wear ties, they should at least tell them to buy a clip-on. This would suggest they are at least aware that ties can be used as a weapon.
if you ever actually feel unsafe then interview the pt with security staff present in a public area
Problem there is you sometimes don't know there's a danger until after the fact....
I know this may have been in jest, but in several places, if you fight back, even in self defense, you can get in trouble. In several institutions, even if the patient attacked first, there are specific rules of engagement. E.g. some places, any action you take then must be to escape, not to fight back. Others, you can only respond with similar force.
