An 85-year-old man with peripheral vascular disease, coronary artery disease, congestive heart failure, dementia, a history of falls, and atrial fibrillation, which was being treated with warfarin, was admitted for a left transmetatarsal amputation. On postoperative day two, the patient slipped as he was getting out of bed to use the bathroom. He hit his head on his IV pole, and a CT scan demonstrated an acute right subdural hemorrhage. He subsequently suffered eight months of delirium before passing away at a skilled nursing facility. How could this incident have been prevented?

Hospitalization represents a vulnerable time for elderly people. The presence of acute illness, an unfamiliar environment, and the frequent addition of new medications predispose an elderly patient to such iatrogenic hazards of hospitalization as falls, pressure ulcers, and delirium.1 Inpatient falls are the most common type of adverse hospital event, accounting for 70% of all inpatient accidents.2 Thirty percent to 40% of inpatient falls result in injury, with 4% to 6% resulting in serious harm.2 Interestingly, 55% of falls occur in patients 60 or younger, but 60% of falls resulting in moderate to severe injury occur in those 70 and older.3
A fall is a seminal event in the life of an elderly person. Even a fall without injury can initiate a vicious circle that begins with a fear of falling and is followed by a self-restriction of mobility, which commonly results in a decline in function.4 Functional decline in the elderly has been shown to predict mortality and nursing home placement.5
Inpatient falls are thought to occur via a complex interplay between medications, inherent patient susceptibilities, and hospital environmental hazards (see Figure 1, below).
