My friend was sitting outside then a patient approached him asking for a cigarette he said he doesn’t have any. He looked around and saw a man wearing a mask from the hospital staring at her and following her. She said to my friend I think I am going to kill myself, jump in front of a car or commit a crime. My friend who is a healthcare worker asked her to come with him inside the hospital he asked her what happened to her she said her family died. And her friend too. My friend asked her to wait for him and went to the ER and said I work here and a patient just approached me and explained how he is concerned over her safety. They kept dismissing my friend and reapting that a psychiatrist discharged her. The woman said then she never seen a psychiatrist and she was just left on bed for two hours. The man then whispered to my friend she is just drugs abuser. My friend left after hearing this and tried to explain to security what happened they said she is just a homeless person. We dont keep them here. My friend tried to call a social worker and no one was available. Can a hospital kick a suicidal patient out?
