Not necessarily.
I used to work for a social services type agency and on occasion had contact with clients who voiced suicidal ideation or had actually attempted suicide right before they called me. I drove many of them to the ER and, at least in the 1980s, it wasn't that easy to get admitted to a psych unit. Even for people who had actually attempted suicide before showing up at the ER.<snipped for space>
I agree, GrainneDhu. I'm sorry, that had to be so hard! It should IMO be the case they're held but it isn't around here, either - lack of resources, and I suspect it's the same in a lot of places. One other thought, in my experience by the time the pysch docs/nurses arrive, the person's in a somewhat better frame of mind. If someone's only gone through "the system" once I don't think they realize what they just got themselves into in terms of hospital, psych clinics, etc. Which is probably what they need but they hate/hated it. Those who've done it more than once know how to talk themselves out of being committed/hospitalized. All IMO and sadly based on several people I know. Just to be clear no fault of the doctors, staff, etc. - they've got a practically impossible job IMO.
My comment's also based on my experiences of waiting in emergency rooms... sheesh. I had to go in a few months ago and waited for 12-13 hours before I saw a nurse or doc, because a lot of people were (justifiably) taken in ahead of me. While I waited, there was this woman who made my heart ache. Hospital/ER was out of beds, out of chairs, and wouldn't let me stand for awhile to give her the bed I'd been on for 6 or 7 hours. She was sobbing for HOURS and every so often would stop to say over and over "please someone help me." It was hard to understand what else she said but the gist was she wanted to kill herself but didn't want to die. She finally got a bed and I think she was so exhausted she couldn't help but sleep for a bit. By the time the psych consult doc got there she was a little more "together" and convinced them she was ok enough to go home with discharge orders to see a psychologist. I (obviously) still think about her and wonder what happened.
Anyway I'm sorry that was kinda OT but it reminds me how easily someone who may still be in danger can be discharged. Relating back to the girls and their families, I feel so sad for them. It made me even more sad to hear about what happened with Misty today. I feel like she needs to at least know her daughter is safe and alive. I'm not much of a religious person so it wouldn't be right to say my "prayers" are with them but the sentiment is the same, my thoughts are sure with all of them.
ETA: I was there for dehydration and saw everything from car accident victims to gunshot wounds to "construction nail through the head" (eek!) to this distraught woman... felt sort of stupid for being there for dehydration after all that - would've probably left if not referred there by a doc.
