Should I call the hospital after my grandmother fell?

When the ambulance comes to get her the EMTs need to be told she has Dementia so is not able to make informed decisions for her care. I so hope one of your parents has POA (Power of Attorney).
She needs a full physical. A test for a UTI (urinary tract infection) with a culture so the correct antibiotic is given. Mom and Dad need to tell the doctors about grandma getting aggressive enough 911 had to be called. There are medications for this aggressiveness. Its no longer what grandma wants, its what is best for her.

If grandma can afford it, Memory Care would be a good option. If she does not have money, then its a Longterm Care Facility with Medicaid helping to pay for her care.

Grandmom no longer has the choice of where she will live if it effects your family. If Mom and Dad work, they also cannot care for her, too. Its hard dealing with someone suffering from Dementia because its so unpredictable. They need 24/7 care.

When in doubt, always call 911.

Wishing you and your family the best.

Yes, do call 911. She doesn’t have to know until they show up at the door. With dementia patients, it’s sometimes best not to let them know what you’re doing on their behalf because that gives them time to freak out before it happens. She needs more help and this is the way to get it. Good luck and congratulations for being a responsible and concerned grandkid!

What a kind and smart teen you are to take the time to research and reach out on behalf of your grandmother. She’s definitely blessed to have you in her corner. A diagnosis of dementia means that, sadly, your grandmother cannot be responsible for making good, sound decisions. She’s relying on her family to make good choices for her, even though she may not be able to appreciate that now. Your parents need to have her seen by a doctor as soon as possible, if she won’t go willingly, they can call 911 and have her transported. Your parents need to tell the doctor and hospital staff that your grandmother has made threats, and isn’t safe to live in a home environment. This may sound harsh, and it may look that way when it happens, but it’s the way to get her the help she needs. This isn’t your responsibility, it’s for the adults to handle, but it’s amazing to see your concern. I wish you all the best
