I am so shocked at all the explosive angry posts on this thread!! Take a step back and think about this logically - could it actually god forbid be because they feel family input is the best approach for the patient?! And they won't 'expect it' a simple conversation with the staff setting out what you can and can't manage is all that's needed. If noone says anything they will just think you are all ok with the arrangement. They won't begrudge you, they can't change something they aren't aware is a problem. It's also not 'you' and 'them', approach its as a team who are working to make sure your mil is safe - this is why they will ring you to come in, they recognise your family are best placed and skilled at managing her distress and not them. But if you can't do it then they absolutely will, it might just not be with the finesse of those who know her inside out.
It's a hard line to tread as alot of families would be incredibly angry if you hadn't contacted them to help! So open conversations are probably the way forward.
We dont want to sedate people - they fall, they break things, they become confused, even more aggited in some cases. Sedation =not good=absolute last resort
Also to address some of the language used in previous posts, patients with dementia are not 'disruptive' , they have a set of behaviours associated with their disease that can be successfully managed in a number of ways, they certainly are not purposefully doing things to disrupt or upset people. They are normaly scared, in pain, disorientated and especially in a ward environment.
Get the hosp social worker I volved as they are often good as objectively assessing and talking to relatives where care needs arnt being met at home and putting forward/recommending other care options e.g. care homes. It is a very difficult decision but they are skilled at supporting through this.
Best wishes and hope she gets better soon x
