Is a stage 2 bedsore an indication of end of life?

My mother went on hospice on January 1, 2021 with a terrible pressure sore on her heel, and she had it when she died July 26. Hospice did a wonderful job treating and dressing that ghastly wound to keep it from becoming infected, so it had nothing to do with the end of her life and fortunately did not contribute to the ending of it either.

The best predictor of the end of life is age itself. Life expectancy varies from person to person. 70's, 80's, or 90's. Disease plays a secondary role. As one approaches his life expectancy, the body becomes more vulnerable to acquiring a disease. A disease or health problem will give the final push. However, nobody can fool Mother Nature. If it's your day, you can die from a common cold without any bedsores.

is your mom on hospice. ? If not, please consider asking. My mom just recently passed, and hospice is a Godsend. My mom s hospice nurse knows when to get tools in advance into my mother‘s room. First came to hospital bed table, then the wheelchair, then the hospital bed, and the special wheelchair. I would say that a hospital bed would be advantageous for your mom. I don’t know if she has one.. But not only is the tools that your mom needs, staffing becomes more hands-on. The registered nurse came weekly, the CNA came twice a week, she was bathed, Did her nails, manicures she loved them. A minister came almost weekly, who my mother absolutely would light up when he walked through the door.

My mom’s had bed sores starting and I truly believe if it hadn’t been for Hospice that the staff at the memory care would not have been on top of this the way Hospice was.

I Wish your mom and you blessings in this journey

She is close to the end of life because of her advanced age, independently from Alzheimer's and bed sores.

It may reoccur and it is "probable" that it will given age, condition, mobility. The stage of a bedsore is fairly irrelevant to its prognosis. A stage II may be healed with treatment, lessening of pressure, or it may progress until the sore is all the way through all tissue and bone is exposed. Much of this depends on ability to lessen pressure, deliver nutrition and treatment, keep area clean of urine and feces, treat the sore appropriately, and etc.
As to whether this or any sore is an indication of end of life nearing, the age and general condition indicates that yes, you are approaching end of life irregardless of bed sores. The bedsores are but one side effect of all that happens at end of life with lack of muscle, lack of mobility, poor nutrition, incontinence and etc.
Often bedsores move to sepsis which can kill very quickly with failure of all major organs.
I am uncertain why you wish to list "bedsore" or anything else as an indication of "end of life" approaching. You don't need a specific for that. The end of life is approaching and general condition will tell you this. Whether that means weeks, months or even years you cannot know. Your MD may be willing to order hospice tho on his "best guess" that with all that has occurs the end of life is "likely" within the next 6 months or so. If your Mom is still living then (or even "better") she can be reassessed for need at that time.
Do know that Hospice doesn't mean that a bedsore won't be treated. It will be, as the goal at end of life care is comfort and quality of life.
Best out to you.

Gut reaction..
A Stage 2 pressure sore leads me to think that she is not getting the proper care that she should be.
There is a particular pressure sore called a Kennedy Ulcer that some get and that is usually observed up 72 hours before death.
There are other indications that a person is "actively dying". Skin breakdown, breathing changes, skin discoloration, increased sleeping, sometimes a burst of energy, refusing food or fluids are a few.
Is she on Hospice? If not it might be a good idea to call a Hospice service and have them step in. She will remain where she is but there will be more eyes on her, more direct care for her. And the goal of Hospice is the same as yours ... mom's remaining time to be pain free and comfortable...
2 good ways to prevent pressure sores are:
Proper mattress that will relieve pressure.
Repositioning her at least every 2 hours.

People in nursing homes often get bedsores if not turned regularly, and even often if they are, so no a bedsore is not an indication of end of life.
And the fact that your mothers is now closed and healed is a very good sign, as often it can create issues if it doesn't heal up.
The only bedsore that is pretty much a death sentence, or a sign that death is imminent is what is called a Kennedy ulcer, and it's usually located on a persons tailbone, and can be quite large.
So for now just enjoy whatever time your mother has left, because at the age of 96 you know she doesn't have a lot lot of time left here on this earth.
Blessings to you and your mom.
