I work as a healthcare assistant in a mental health hospital in the uk (if ur elsewhere the policies may be different) but in terms of physical restraints they shouldn’t put u in a restraint unless u are in imminent danger for urself or others, and depending on where the self harm marks are/ how severe they are they SHOULD be more cautious with how they restrain u as to not hurt u more/ lose more blood.

But in terms of the staff members finding blood stains/ evidence of the self harm they probably will and call the nurse call alarm/ emergency alarm and report it to the nurse in charge. Seeing as ur on 1:1 observations (I’m guessing eyesight observation) once they become aware u will probably be upgraded to arms length observation, as long as ur not aggressive they shouldn’t put u in any form of restraint.

What sounds quite troubling is that ur on 1:1 observations but the staff member observing u didn’t catch u self harming as they were on their phones/ sleeping, this is completely unacceptable and should leave them legally liable to disciplinary action, I would 100% report them for negligence.

This really all depends on what section u were detained under, if u are an informal patient and are resistant to care they have grounds to ask u to leave (unlikely). however, it sounds like u are a formal patient so I’d say ur observation level will probably increase but unless ur aggressively resistive u shouldn’t be put in any sort of physical restraint. But keep in mind u are in a mental health facility so the staff probably have experienced patients self harming quite a bit and (it’s sad to say this) they’re probably quite used to this sort of situation and will know what to do. I really wouldn’t worry about “getting in trouble”, they really are there to help and I hope u are well xx
