Hi, I spent many years working in care and that includes care homes, I understand your issue and the frustrations it causes, in a care home that specialises in dementia or at least claims too ( in my experience its only really a couple of people that actually understand dementia, the rest are basically given 1 or 2 training videos and then left to do everything ) there are a number of issues here, often a person may believe that they are being kidnapped or something similar ( I'm putting this in a very very broad way so please stay with me here haha ) so they lock themselves into rooms believing it's for there own safety, it's rare that a care home has locks these days however you should have a lock on the outside, this is incase a person keeps themselves in there room and it becomes a safety issue or a health issue, the doors should have latches aswell to open in both directions, although most staff would be unaware of this other than the fire marshal that day ( at the start of shift a fire Marshall should be allocated who is appropriately trained ) care homes are dictated by the CQC and it is illegal to lock a patient in there room at any time, locking them out is a different story, lots of paper work and other procedures I won't bore you with ) but if staff lock a door with a person inside then the home can be in a lot of trouble usually resulting in fines and loss of jobs, so yeh, can't be done, a good practise is label everything with a name, care homes often sow names onto clothing due to residents walking and taking clothing. You can't restrain anyone in a care home generally speaking and staff arnt trained to do it, even if they were trained in a mental health facility, they couldn't use restraints in a care home, all they can do is redirect people useing distraction techniques and verbal prompts. So yeh, label everything, use sticky labels if you have too and record everything she has, the care home should have done the recording already but I bet its not done properly, if it is, it's a very very good home. Give staff a copy of what you've recorded, and when your there do a check, if something is missing then ask staff to find it, you CAN, get a lock box for jewelry and things, I would advise to get one, they are little boxes and godliness. Remeber you can't take something away from a person they would have normally, same with something that is there human right to have, that's called DOLS and to explain that here would take a lot more explaining haha. so providing your family member has retained capacity they have a right to hold the key with them for any lockbox. If you went to a carehome and properly, you would see so many things that could be classed as abuse, for example, it's institutional abuse to make everyone get out of bed and have breakfast at a specific time just because that's the rules, however every care home I've worked out the staff have to get everyone out of bed, washed and dressed between 730 and 830 in time for meds and breakfast, of they miss that or refuse to get up, they are pressured into getting out of bed and often told theve missed breakfast, which is the very definition of institutional abuse, but the home will always say its not..but remeber, the staff there are likely on minimum wage or close to it, probably have 13 hour shifts, havnt really had a break that day, they won't finish on time, probably cleaned someone every time they soiled themselves and then told off for being behind, the home won't have enough staff and working on a bare minimum, often being forced to use agency staff that don't know the residents at all due to keep to what's known as safe staffing levels which is a legal requirement however it isn't really enough to do everything, so often, they won't have time to watch every resident at all times, even though that's what the care home advertises, it simply isn't true other wise you would have 24 residents and 26 floor staff ( 2 to cover breaks ) care homes are a money making buisness, hence why they charge 1000's weekly but pay minimum wage, I would also reccomend setting a meeting with your key worker to resolve the issues or put something in the care plan to mitigate risks, something that you agree is suitable. If its in the care plan, it has to be followed, care plans are legal documents. Hope this helps and sorry for the long winded answer, any other questions feel free to ask and I will do what I can to advice, if you want to know my credentials, ba hons health and social care, and was a registered manager for a number of years before having to stop work due to genetic illnesses
