Mother-of-two Michaela Fowler, from Wakefield, fell from a stairwell at Pinderfields Hospital in June 2018, the day after she was admitted with breathing difficulties.
The family of the 60-year-old, who suffered with chronic obstructive pulmonary disease (COPD) and osteoporosis, said she appeared to be delirious and wandered off after a nurse left her alone for a few minutes to change some bedding.
