Hello Snuffy
In the past I have always found the Inspector at Care Standards (CSCI) who had special responsibility for the care home was very approachable and friendly and helpful. There is usually one inspector who does all of the Inspections (2 a year) of each home - so that there is continuity and he or she can start building up a picture of the home - in all its complexities. They are very aware that their visits & Inspections only give them a snapshot of the home & what goes ton here but they receive letters, tel calls all the time & know a great deal about the home. They also keep everything totally confidential.
You can easily find out who the Inspector for any care home is from the website Sandy has given - the CSCI. Then you could give them a call - you may find a duty Inspector answers the call or a receptionsit but if you wish to speak to a particular Inspector that can be arranged.
I believe (only my opinion here) that every care home resident has the right to see their own records, just as we have the right to ask for all our health records now - (I understand there can be a charge for providing these !!) - that includes all important Care Plans - and of course in the case of a resident who needs someone to lookafter their affairs or advocate for them (as all our relatives here do) then their next of kin or carer can act for them & request to see records.
The other thing you might find useful is an Advocacy Service - at a time when emotions run very high it is difficult to stay relaxed (putting it mildly - from experience I speak !) adn when dealing with care homes & you are on your own - its not easy (again have had lot of experience - lonely experience) - ther eare organisations that will offer services of an advocate who can accompany you & speak for you if necessary - they remain totally unprejudiced & are there simply to make sure your views are made clear and that you understand what has been said too (thats my interpretation anyhow) - its hard doing these things on your own. If you are - try to write everything down as it happens and take someone with you if you can. Take care.
