Continuing Care Assessment meeting - Advice sought

Hello,
I have a request for advice concerning what to expect at an "all agencies meeting" concerning the ongoing care for my father.
Some time yet (end June) but things moving fast.

Brief background: Father in 80's with moderate Alzheimer’s.
Been in half-way care / nursing specialised as result from discharge pathway from multiple hospital stays for UTI.

Wasn't being looked after properly by second relationship partner which included estrangement from children. Placed in temporary home who assessed him as needing nursing care. Poor physical state when arrived at hospital hence discharge into care.

Mental capacity deteriorated whilst in home. Social worker started to take control of affairs but then stepped back. Care authority after 4 weeks decided needed another month in home to assess needs. Now have stated Assessment completed and wish to arrange all agencies meeting (including us) at home.

I don’t know anything about the format of meeting and what sort of decision will have been made or need to be made on behalf of my father. I know funding of placement will be covered but don’t know what sort of questions will need to be answered of if this meeting is for the “agencies” to decide and then inform us (children) of outcome.

Father is past mental capacity, had no POA or EPA with either us or partner. Social worker / Court of Protection will be in charge of finances of welfare considerations. We are not concerned with regard to sale of assets or protection from home charges, just really Dad’s welfare so he receives best care.

Main areas of advice needed:
What questions do I need to be prepared for?
What are possible outcome of meeting decision?
What is the “all agencies meeting” (after assessment) concerned with?
And, what are outside the scope of this meeting?

Additionally, I have a couple of concerns regarding the (very good) home he currently is in.
Over the past couple of days he has not been drinking very much. The carer stated this and addressed my father with a “you must keep up your fluids” comment but them promptly left the room. My father isn’t capable to immediately process this and will not then drink without patience with his initial refusal and perseverance eventually overcomes this with consumption of a glass of water. I don’t think this is being done and have concerns this might result in rapid deterioration should this continue to occur – How can this be handled – ask for meeting with home manager for reassurance or directly asking staff. I hope this is my overreaction.

I don’t know how much hand-over information gets exchanged between shift staff. If my father has not eaten / drank much during the day should there not be some sort of concern log written so this information is not lost between changes of staff?

Thanks in advance for any advice. New to posting so apologies if this is in the wrong section: moderators, please move and advise.
Did search but couldn’t find suitable topic for this query, if there is one, please just reply with section/title and I will research. Any search terms on web / links appreciated, I’m prepared to do the leg-work, but just need some key words to start queries on.

Lastly, I only have time to concentrate on this specific issue at the moment, so by all means state opinions on related aspects to this but please excuse me from supplying any response as I have to focus all of my efforts of getting the best for my Father, and only this.

Regards BB
