Prevention of Falls in Community-Dwelling Older Adults

A 79-year-old woman presents for her annual wellness visit. She reports having fallen 9 months ago and again a few weeks ago. She does not remember the details of the first fall, but for the second fall, she notes having tripped over uneven pavement while walking outside of her home. Despite some difficulty, she was able to get up unassisted and did not seek medical attention; she recalls having taken an over-the-counter "sleep aid" the night before. She said she has no fear of falling, dizziness, or loss of consciousness. Office staff perform a Timed Up and Go test, and it takes her 15 seconds to complete the test (>= 12 seconds indicates an increased risk of falls). How would you evaluate this patient and manage the risk of future falls?
