The American Geriatrics Society recommends at least annual screening for falls in the elderly population. Medicare is also requiring fall screening as a HEDIS measurement. Despite these requirements, screening rates are low. Additionally, the multifactorial nature of falls makes it difficult for clinicians to sort through the causes of falls in any given patient unless they have a framework for evaluation.
1. Discuss the multifactorial nature of falls in the elderly.

Falls are a substantial source of morbidity and mortality in the community-dwelling elderly, leading to physical and psychological injury, increased healthcare costs, and risk of long-term care admission. There are multiple risk factors for falls, including a hazardous home environment, increasing age, a history of falls, and polypharmacy. Physicians caring for elderly patients should perform annual risk assessments and be prepared to provide advice on fall-risk modification strategies.
Falls are a common occurrence among the elderly, with greater than one in four community-dwelling elderly falling each year.1 Falls are a significant source of morbidity and mortality in the elderly, and are the leading cause of death from injury in persons older than 65 years.2 In Floridians greater than 65, unintentional falls are the leading cause of fatal and non-fatal injuries.3 Falls in the elderly can cause physical injuries including fractures, lacerations, traumatic brain injury, and wounds. Recurrent falls increase the risk of long-term care institution admissions, and may lead to a fear of falling and patients imposing functional limits on themselves.4 Falls in the elderly are also expensive, with Medicare costs for falls in 2015 costing over $31 billion, mostly due to hospital-associated costs.5
There are many risk factors for falls, and the combination of such factors cause an increased likelihood of falling.6 The leading cause of falls is a hazardous environment, with increasing age, a history of falls, lower extremity weakness, arthritis, use of a cane or other assistive device, and visual and cognitive impairment.4,7 Certain medications increase the risk of falls including antidepressants, anti-hypertensives such as diuretics, antipsychotics, anti-convulsants, benzodiazepines, sedatives, and hypnotics.8 Polypharmacy, in particular the use of more than four medications, increases the risk for falls.9 The American and British Geriatrics Societies recommend routine screening for falls at least yearly, with a brief screening for low-risk populations.4 Patients who present with a history of falls, or who display gait and/or balance abnormalities on examination should undergo a more thorough evaluation. Discussing and managing fall risk is also an annual Medicare Healthcare Effectiveness Data and Information Set (HEDIS) requirement.10
The evaluation of falls in the community-dwelling elderly is primarily based on the history and physical. Given that falls are usually multifactorial, a detailed history and physical can help to differentiate the extent to which external, environmental factors and intrinsic, personal factors contribute to a fall or history of falls.6 The evaluation of a patient with a history of falls should begin with a comprehensive history. One of the most important parts of the history should be a detailed account of the patients’ previous falls. The provider should ask about the location and time of the most recent and previous falls.6 It is important to note the activities in which the patient was engaged prior to and during the falls. Providers should also inquire about the patient’s history of chronic diseases, such as osteo-arthritis, chronic musculoskeletal pain, and diabetes, and the status of these diseases.11 Providers should thoroughly review the patients’ medications list. Studies have shown sedatives and hypnotics, antidepressants, and benzodiazepines to be significantly associated with falls.12 Other classes of medications including antihypertensive agents, neuroleptics, narcotics, and nonsteroidal anti-inflammatory drugs also increase the risk of falls.13 Additionally, patients on more than four medications are at an increased risk for falls.14 A patient’s neurological status including cognitive status should also be assessed. Cognitive impairments can be determined during the history.6 The patient’s evaluation of their ability to complete the activities of daily living should be noted.15 The history should also include questions about the patient’s home environment and social supports.16 The physical examination also plays an important role in the evaluation of an elderly patient with a history of falls. It should hone in on the intrinsic factors that may play a role in falls and include assessment of the patient’s vital signs along with a vision and hearing screening. A comprehensive neurological examination should also be performed including an assessment of the patient’s gait and muscular strength. The patient’s postural stability and coordination can be evaluated using a variety of tests such as the Timed Up and Go Test, Tinetti’s Mobility Scale, or the Physical Performance Test.15 The Timed Up and Go Test is widely used. With this test, patients are timed while covering a fixed distance after rising from a standard chair, covering the required distance and then returning to a seated position in the chair. The patient’s recorded time is compared to the mean time for other adults in their age group.17 The Tinetti’s Mobility Scale is a 16-item assessment of a patient’s gait and balance. The patient’s gait and balance are gauged in a variety of situations including transferring and changing directions. The Physical Performance Test helps identify functional and physical changes in elderly adults. Laboratory studies should be directed by the results of the history and physical and may include a complete blood count, BUN/creatinine, thyroid stimulation hormone, Vitamin B12, and 25-0H Vitamin D levels.6,15,16 These studies may rule out reversible causes of falls including anemia, dehydration, and nutritional deficiencies. Radiological studies and other diagnostic tests are often not needed; however, imaging of the brain and/or spine, echocardiography, and Holter monitoring may be recommended.
Fall-risk modification counseling for all elderly patients is recommended by the U.S. Preventive Services Task Force.18 Due to the multifactorial risk factors for falls, there is no single superior method to prevent falls. While interventional approaches targeting a single risk-factor are effective, numerous studies validate that a multifaceted, yet individualized, approach to interventions is most effective.19,20,21 Physicians who are unable to coordinate a multifactorial intervention from their office may consider a referral to a fall prevention program. Exercise programs including targeted muscle strengthening, walking programs, and gait and balance training, when performed under the supervision of a physical therapist, significantly reduce fall-risk.19 Fall prevention programs incorporating balance retraining, including Tai-Chi & the Otago exercise program, are most effective.19,22,23 Patients requiring assistive devices should undergo an occupational therapy evaluation to ensure they are using the correct device and in an appropriate manner.24 Referral to an optometrist or ophthalmologist is indicated for any patient displaying a vision impairment on examination. It should be noted, however, that patients undergoing correction for a visual problem may initially experience an increase in falls as they adjust to their improved sense of vision and perception. Since hazardous living environments are the leading cause of falls, a home safety assessment is an important part of a fall risk modification. An assessment should be performed by family members instructed on safety measures or a home health agency as part of a comprehensive falls prevention program. Identified hazards should be removed, and the home environment modified (Table 1).
Appropriate home safety assessment and modification was shown to decrease risk of falls by 20 percent in patients recently discharged from the hospital.24 A patient-oriented home safety checklist is available on the Centers for Disease Control and Prevention’s website.25
Falls are a significant source of physical and psychosocial morbidity, and increased financial costs amongst the elderly. Physicians should perform screening for falls on their elderly patients at least yearly, and the evaluation for fall risk should include a review of medications, co-morbid conditions, physical examination including gait evaluation, and laboratory or other studies for select patients. Fall prevention programs should be multifactorial in nature including physical strengthening and balance programs, home safety assessment and modification, and medication review and modification.
