You said it. Saves me a bunch of bandwidth.
1- privacy
2- abusers know where the cameras are
Now, if family would set up surveillance without staff knowing, that would be different. Of course residents without family or support are more so a target than those who have someone caring about them.
I think a big problem is our health care system. Fees for retirement homes are huge, yet it seems they never have enough money to hire caring staff. It is a scary dilemma.
You have touched on the heart of the problems but it goes deeper. Nursing homes, skilled nursing facilities, assisted living, etc. all have one thing in common they're facilities for people that are either aged, mentally unable to care for themselves at home or chronically ill.
Here's the problem. Regulations vary dramatically from state to state. I happen to live in Connecticut and our state regulations for nursing homes and assisted livings are extremely rigid. Our tough regs came after the mid-sixties when there were some scandals in our facilities concerning abuse or neglect. The State Dept of Health inspects each facility on a regular basis and without warning beforehand.
I am a nurse, but for 10 years I ran a nursing agency, had 4 office locations in the state. We provided temporary nurses and nurse aides for nursing homes primarily on a shift basis. If a home was short a nurse for 11-7 night shift, they called us, we sent a nurse. But in the beginning when we were acquiring clients (nursing homes) I personally went in to do the shift myself, just to get the 'lay of the land' the protocols, procedures, etc. That way I was able to tell my nurse before she went to the place how it worked there. I've worked in no less than 10 different facilities, and reported 'cold' without knowing a thing about any of them. There was a vast difference between those operated by 'corporate' owners and those run by private families. Nevertheless, they were all compliant with our rigid state regulations.
My sister is also a nurse and moved to Florida. She got a job as an administrator for one of the nursing homes there. She was shocked at the differences in the regulations between our state and Florida. She hated it because she was a old school nurse as I was and we always did things 'by the book' and to the letter. Florida wasn't like that at all. Their regulations are lax, their inspections aren't regular and when they happen, many infractions are ignored or overlooked. The quality of care just wasn't up to par. But this is the case across the country. Regulations differ from state to state, some facilities are wonderful with a loving, caring staff. Some are horrible with staff that's there for the buck, not for their love of geriatrics.
As a nurse, I have had only three experiences where I've witnessed and reported either patient abuse or nurse abusing drugs. Yep, one of my head nurses was stealing narcotics. The patient abuse was something I never witnessed, but I listened to the old man who I found crying one day. He was shaking and I asked him what was wrong. And he said that the aide threatened him and was 'rough' with him. The first thing I did was remove the aide. I sent him to work in the dining room moving patients in and out. Then got on the phone with my supervisor and told her what I suspected. The aide was called in to the supervisor's office and fired. He never denied it and left without a fuss.
Here's the bottom line - in my opinion anyway. Training of nurse's aides is paramount to having a staff that's reliable, caring and considerate of their patients. Without supervision of aides, the bad ones get away with things. The next thing is listen to the patients, ask them, 'how was Mary today, did she put your favorite dress on today?' 'How was Peter, did he make sure you got everything you need?' ASK. Then look for any signs from the patients, signs of fear, signs of finger marks on a patient's arm, signs of skin breakdown - that means they aren't being washed or changed properly. There's so many things that a nurse's eyes can see and ear can hear that will certainly catch any type of patient abuse before it goes on any further.
Sorry that was a long post. I got carried away. But patient abuse should never be tolerated in any setting, whether it's a hospital, rehab facility, nursing home or VA hospital -- which by the way, I've witnessed some pretty bad things in our VA hospital.
