Actually, this is one area where the USA is street ahead of the UK.

My late wife Jacqui's mother Edie just died in stroke related circumstances. She had had a stroke (not a major one) some years ago and her left leg had remained a bit less controllable. Last week she fell, in her semi-sheltered (retirement community) flat. No limbs were broken, but she banged her head, and a blood vessel in the brain was damaged. The medicine for her blood pressure meant the bleeding continued. It was inoperable. After about 12 hours in hospital (Queen Mary's Sidcup), she died.
