A Personal Assistant in the context of caring usually means someone supporting/enabling an impaired person to live as independently as possible. Some people believe that the term "carer" can carry negative connoations of being patronisied and "cared for"
Pat and I are looking for someone to support Pat rather than "care for" her. Duties include domestic work, driving and companionship but also just being around.
Perhaps you might be able to advertise locally for a Companion, which may cover things rather better than looking for a Carer. For some reason, the word 'Carer' seems to imply a slightly up market Tea Lady for many people and a Personal Assistant may sound a bit secretarial.
As carers, we probably do all of the above, don't we? ...
Sadly, within the present system I suspect your requirements do not exist. In my life I have been a PA at such a level of responsibility and financial reimbursement as to now make me blush; however, I am, and very proudly non-PC so, a 'carer' at such a level it makes me blush that I can't afford the balm for the cheeks. I love, therefore I care.
Never do I find it patronising until I cross the path of the various agencies and the minefield that is a system typical of today's policy making mess of the powers that be. The system allows only care within those parameters laid down by the 'rules' and the finances for such defined by those same rules.
I think that what you need you are going to have to pay for - a nurse come companion - and it costs.....lots of money. Where you will find what you are looking for will be within a private nursing agency. I doubt very much whether you will find much shared experience of this on TP.........but I could be wrong (it has been known!).
