The hospital guards used to escort me to my car after I worked the late shift at the YNHH Emergency room as a Medical resident. Why? Because New Haven is the second most dangerous city in Connecticut after Bridgeport. It's 37th in the country.
And one night when I was working they brought a 18 y.o. black women to the medical part of the ER from the psych unit? Why, because her heart rate was 150 beats per minute. Well, that's way above normal, so I proceeded to examine her after talking with her.
Turns out her ex-boy friend was chasing her down Howard Avenue with a knife. After a short time, her heart rate returned to normal, her exam checked out fine so I escorted her back to the doctor who had brought her to see me.
