This morning I received a call from my mother's care center telling me she fell from her bed, hit her head, it was bleeding and they called 911. I rushed to the hospital and from where her wound was I immediately questioned in my mind the logistics of her fall. When I finally spoke to the manager on duty I found out that the CNA, who was the lead CNA this morning and very experienced, had just finished changing mom's "briefs", turned to put them aside and in that split second, mom fell out of bed, hitting her head on the carpeted floor. She has two cuts and was bleeding badly. She has been in a hospital bed at the facility and they are NOT allowed to use guard rails. We had mom in a normal double bedded mattress and box springs and her ability to move around in her bed was next to impossible as she is totally infirmed. The facility recently encouraged me very strongly, to change her bed to a hospital bed, for the CNA's benefit of changing her and moving her with the ability of the bed being more portable. I complied immediately. Soon after that they suggested I buy a floor mat in case she falls as it was found that mom actually was able to shift her body some. I bought the mat immediately and they use it. However in this case, the CNA moved the mat as she needed to change mom and standing on the mat while doing that did not make sense. Apparently the CNA left mom on the edge of the bed, on her side for a second to turn away and put the soiled briefs in a bag and then on a chair within arm's reach. The next thing she knew, my mothers yelped in pain as she hit the floor. The rest is what has been mentioned. The manager on duty said these exact words. "The fall was preventable" With that, I plan on making the facility pay for all medical bills that the insurance will not pay and over and above that, is there anything else that I can request from them, aside from a plan to prevent this in the future? How liable are they and should I bring a lawsuit for negligence? Mom is 91 and has been in their care for 3 years and they love her dearly. The CNA is beside herself with regret and I really like her, but this is something that could have been prevented and we are not out of the woods yet. Any advice would be helpful.
