Most of their workload is bullshit. People with colds and sore throats, depressing people using ER as primary care, assholes using 911 to score Medicaid cab vouchers.
And at any time, any number of people can show up with any kind of personal tragedies from stokes to various traumas. My sister quit after a 13 year old bled out from a gsw, and she walked out of the room and got kicked in the head by an prisoner who had been stabbed after he bit the ears off of three other prisoners, and broke the arm of a guard.
