@theunknown - Id like to mention that no one is talking about a DoL order - which is something that has to be ruled by a court. What we are talking about is Deprivation of Liberty
safeguarding assessment.
My mum had to move to a secure care home because she would be at risk being outside on her own - she used to get on random buses and end up very distressed at the back of beyond; she would also go walkabout in the wee small hours of the morning, very inadequately dressed, and would bang on random peoples doors because she was lost. She also had no traffic sense and would just step out into the road, whether it was safe or not and was very likely to cause/be injured in a road traffic accident. For these reasons I could not keep mum safe and so she moved to a secure dementia home and was not allowed out unaccompanied, but that didnt mean that she couldnt go out at all. The care home organised weekly outings, which mum went on, and I used to take her out most times I visited.
Because she was not allowed out unaccompanied she had to have an annual assessment to make sure that this was reasonable - the so-called DoLs assessment.
