Hey 563501: Welcoming to the Community!Sorry that you mom is unstable in her living situation. Finding suitable (and agreeable) living situations for people without BPD can be challenging, so you likely have a higher level of challenge.
My mother has BPD and dementia and has been very unstable in her independent senior living apartment.
It might be helpful to check out the link below. Some guidelines are mentioned, as well as a link to whatever state you live in.
www.assistedliving.com/laws-by-state/My mom wasn't the one with BPD/BPD traits, but she spent the last 5 months of her life between hospital stays and skilled nursing facilities. Nursing facilities have more regulations and oversight, than assisted living facilities.
Your options can vary, in accordance with where you live. Possible care options can depend on the level of dementia combined with BPD behaviors. As you do your homework on facilities, might as well document options for different levels of care. Although, she might currently do well in a less expensive facility, with a lesser level of care, her needs will likely change over the coming years. Additionally, other aspects of her health may well enter the equation.
Just before my mom passed, we were close to exhausting all Medicare supplementation for extended care options, so we were approaching an "out of pocket" cost situation. One option we considered, at that time, was a "Board & Care" facility. They are not for someone who needs skilled nursing, but can present a home-like environment, while being considerably less expensive than alternatives. The patients have their own room and then share common areas. There is usually a nurse's aid, or someone with low level nursing skills in attendance to offer 24/7 help with daily care management and feeding. The situations with medical care would vary by patient and their medical coverage.
There is no easy answer, and it will take some homework. I made a spreadsheet and rated various aspects of the facilities. One primary thing for us was to make sure the facility was within a zone for the preferred hospital, where our mom's doctors were on staff. Some of the aspects to look at are: cost, location, staffing level, the facility in general, aspects that might suit your mom, activities offered, etc. If a facility is licensed and rated, you will want to consider ratings, complaints, etc.
When all is said and done, all you can do is make your best effort to choose a facility. I'm in California. Even though we did research, visited facilities, read reviews, evaluated State code violations, etc., we still encountered problems. Institutional-type settings can be environments to catch various infectious medical conditions (staph, MRSA, Influenza, various new superbugs,). Then, there is a battle with bed sores.
Staffing was an issue we became very familiar with, particularly after the day shift left. The standard is to do more with less and to use the lowest skill level possible. The more independent your mom is, the easier the situation is. We found that, with a rather passive patient, who needed assistance to use the restroom, the nursing facilities (as opposed to hospitals) all wanted to put diapers on the patients. Once they do that, it becomes a standard and good luck with getting prompt attention for a change. (then, you have an adult with diaper rash)
I'm sure our situation was unusual. Our mom's original issue was a sudden onset of Pulmonary Fibrosis and a severe UTI. My mom was septic 3 times in a 5 month period of time (many people don't survive one episode). She contracted MRSA at one skilled nursing facility, then contracted another superbug called VRE, while in different nursing facilities. The nail in the coffin was when the last skilled nursing facility had an outbreak of Influenza "A". She was moved to a room with a patient who already had contracted Influenza "A", while recovering from back surgery.
All you can do is make your best effort to find the best suitable facility, for your situation. Then, all you can do is monitor and advocate as possible. Everything is relative to each unique situation and set of circumstances. We had an awful experience with care facilities (and my uBPD sister made everything more difficult). I'm sure others, with a different set of circumstances, had different experiences.
