As your mother already has a care package in existence, she should be assessed on a fairly regular basis. If you are worried that she is deteriorating, you can ask for an assessment. If the decision is that she is no longer capable of living alone, even with the support of visiting carers, they will first of all try to persuade her that it is in her best interest to move into a residential care home. If this fails, then there is usually a case meeting involving her doctor and social services staff. If it is then decided that she is a danger to herself when alone, then they can obtain a kind of protection order which will enable them to advise the family to look for a suitable care home for her. You do have a choice of care home, and can visit by appointment to inspect the home to ensure it meets with your approval. I must add that I am not an expert in this matter, and can only tell you that this was the procedure undertaken for our friend who had lived independently until he was 101yrs, at which time he did become unable to care for himself, even with support. He is now 104 and settled and well cared for. We did look at six care homes before deciding on the best one. I do hope all goes well for you and your mother.
