An estimated one in three adults, aged 65 years or older, falls each year (CDC, 2013).
Fall rates increase exponentially with age; older adults, age 80 years or older, have a 50% chance of falling each year (de Negreiros Carbral et al, 2013).
Falls are the leading cause of death due to injury in the elderly (CDC, 2013).
The most important risk factor for falling is a history of falls, so health care providers need to ask about falls at every visit!
Adults age 75 and older who fall are 4 to 5 times more likely than their 65-74 year old age cohort to be admitted to a long term care facility for a year or longer following a fall (Stevens & Dellinger, 2002).
Exercise is an effective intervention for falls. Older adults should exercise regularly focusing on increasing core and leg strength, as well as improving balance (CDC, 2013). Tai Chi exercise programs are very effective in meeting these exercise goals.
Interprofessional team work is critical to successful fall protection. Geriatric best practices include preventing polypharmacy, ophthalmology consults to assess for diminishing vision (cataracts) and to update glass prescriptions, dietary consults to insure adequate food intake including calcium and vitamin D, osteoporosis diagnostic work-ups when clinically indicated, physical therapy consults to assess gait and balance dysfunction and provide an exercise therapeutic plan, and interprofessional team home visits to conduct home safety evaluations (Gillespse et al, 2012).
Falls are defined as an unintentional lowering to rest from a higher to a lower position, not due to loss of consciousness or violent impact (Kellogg International Work Group on the Prevention of Falls by the Elderly, 1987). Falls often go unrecognized by health care professionals because they are not routinely evaluated while taking a patient’s history or during a physical exam (unless there is frank injury).
Many patients do not admit to falling for fear of losing their independence.
The incidence of falls varies with age. Persons aged 65 to 79 years living at home have a fall incidence of 30-40%. Persons aged 80 years and older living at home have an increased fall incidence of 50%.
Complications resulting from falls are the leading cause of death from injury in men and women aged 65 and older.
Many factors that contribute to fall risk in older adults. The World Health Organization Europe (2004) has characterized risks into two broad categories, intrinsic and extrinsic risk factors for falls.
Intrinsic risk factors include a history of falls, age, gender, medical conditions, impaired mobility and gait, sedentary behavior, psychological status, nutritional deficiencies, impaired cognition, visual impairments and foot problems.
Many older adults have multiple comorbidities including neurological, cardiovascular, metabolic, urinary, musculoskeletal, and psychological disorders that may increase their risk of falls. In addition, medications to treat these conditions may produce side effects that further impair their physical or psychological status.
Extrinsic risk factors for falls include environmental hazards such as uneven surfaces, poor lighting, and unstable or inappropriately placed furnishings, inappropriate assistive devices, ill- fitting clothing and footwear that lacks support.
Falls are multifactorial in nature. Health care providers should always ask patients, aged 65 and older, if they have fallen recently or have a history of falling. If the patient admits to a recent fall, query for specific circumstances surrounding the fall. Inquire about gait and balance dysfunction. A medication review is critical for both prescribed and over the counter medications. Ask your patient about current medical co-morbidities such as cardiovascular disease, musculoskeletal diseases (i.e. arthritis, osteoporosis) and genitourinary (i.e. urinary tract infection, BPH).
For those that have had a fall or a near fall, obtain a functional history. CATASTROPHE (Sloan, 1997) is a mnemonic for a complete functional history.
C Caregiver and housing

S Syncope (any episodes of fainting)

O Ocular problems
P Pain with mobility
H Hearing (necessary to avoid hazards)
E Environmental hazards
Observing your patient’s gait while entering the room, sitting on the exam table or in the chair, and their ability to move around your examination room will provide a tremendous amount of information. Physical examination should include a detailed assessment of the neurological and musculoskeletal system (gait, balance, ability to ambulate, lower extremity range of motion, muscle strength, assessment of extrapyramidal and cerebellar function). The cardiovascular system should be assessed including orthostatic blood pressure readings and heart rate/rhythm. Vision should be examined for reduced visual acuity (i.e. cataracts). The patient’s feet should be inspected as well as their footwear.
The American Geriatrics Society recommends conducting a fall risk assessment during routine primary care visits. High risk groups should have a more intensive assessment including the Timed Get Up and Go screening test.
