Hello OP, I’m a nurse. Ward based care normally refers to a ‘ceiling of care’ - essentially how far medics should go in treating someone.
If someone was deemed to have a ward based ceiling of care, then it usually means that the team feels that they are unlikely to benefit from being admitted to intensive care, with invasive monitoring and breathing tubes.
That isn’t to say that they think that the patient is going to die, but that they won’t benefit from intensive care, and should they become critically unwell, they would be unlikely to survive even with high level support.
There’s still lots of care that can be given on a ward (antibiotics, fluids, monitoring etc), and they aren’t saying that they won’t treat the patient. However they are saying that should they become unwell enough to need intensive care, they wouldn’t survive regardless.
I hope that makes sense, and that things get a bit better for you!
