Falls are a common clinical problem affecting nearly one third of community-dwelling older adults and more than half of institutionalized older persons in the United States. Falling is a major health problem for those older than 65 (Hausdorff, Rios, &Edelber, 2001). In 2005, 15,800 people 65 or older died from injuries related to unintentional falls; about 1.8 million people 65 or older were treated in emergency departments for nonfatal injuries from falls, and more than 433,000 of these patients were hospitalized (Centers for Disease Control and Prevention [CDC], 2005b). Falling occurs among people of all ages, but falling results in higher rates of morbidity and mortality among those older than 75 because of the higher incidence of frailty and a limited physiologic reserve among the aging population (CDC, 2005b). After age 75, white men have the highest fall-related fatality rates, followed by white women, black men, and black women; non-Hispanics have a higher fatal fall rate than Hispanics (CDC, 2005b). In terms of serious injury, falls are the leading cause of hip fractures, accounting for more than 270,000 occurrences annually. In 2000, traumatic brain injury accounted for 46% of fatal falls among older adults (Stevens, 2006). Older individuals who fall are also more likely than other age groups to be hospitalized or institutionalized as a result of the fall or a concomitant serious injury. Fall-related injuries account for 5.3% of all hospitalizations for those 65 years or older (Bell, Talbot-Stern, & Hennessy, 2000; Jager et al, 2000). Women sustain about 80% of all hip fractures (Stevens & Sogolow, 2005). In a research study by Tideiksaar (2005), falls accounted for nursing facility placement in 40% of the population seeking institutionalization. Client education is the cornerstone of fall prevention and management. The gerontologic nurse must explore client beliefs and misconceptions about falling. Older individuals may consider falling to be a normal part of the aging process. For some, it is an expectation of growing old. Individuals who hold these stereotypes must be educated about the normal aging process, which is distinct from diseases and the adverse effects of medications. It is important to tell older adults that the etiology of falling can most often be determined by a health care professional who has expertise in fall assessment and that falls can be reduced and even prevented through some simple interventions (Box 12–1). The treatable causes of falling must also be emphasized in continuing education and staff development programs in all health care settings. Once the clients’ and staff’s knowledge of falling improves, the reporting of falls in an effort to seek treatment may improve. It is crucial for the gerontologic nurse to recognize that older individuals define falling in variable ways and are influenced by perceptions of aging and disease and the context of the situation. For instance, older individuals may not perceive a slip that results in a fall to the floor to be an actual “fall”; rather it may be termed a slip, trip, or accident but not a fall. Box 12–2 illustrates some common reasons given by older adults to explain the fall. The falling event needs to be reviewed in detail to determine whether the person fell to the lowest level (i.e., the ground). Moreover, how individuals define falling is likely to influence the reporting of falls. A fall can be anything that causes a person to unintentionally move from one level plane to another. An example of this is a sudden and unexpected drop from standing upright into a seat or onto the floor. Injuries such as bruising, sprains, strains, or fractures can result from minimal height drops. History taking should be detailed enough for the examiner to envision the details leading to the fall. Refer to the later section Evaluation of Clients Who Fall for specific questions to ask during history taking (Tideiksaar, 2005). Falling, in a broad sense, is a concept that holds negative connotations because it is associated with a decline, drop, or descent to a lower level. As it relates specifically to client falling, the same negative connotation appears to hold true, as evidenced by the plethora of research that presents the significant negative consequences of falling. However, to clients, falling may mean something entirely different. It may not be associated with an actual dropping to a lower level, such as the ground; falling might mean a perceived loss in status. In a research investigation of community-dwelling older adults’ statements about falls, the extent to which the fall was attributed to a person’s own limitations instead of the environment depended on self-rated health, among other variables (Arfken et al, 1994; Sterling, O’Connor, & Bonadies, 2001). Thus the meaning of falling involves several related variables and most likely is determined according to an individual perception of how serious the fall is in terms of daily living. Numerous age-related changes can predispose older adults to falling, especially when these changes affect functional ability and give rise to sensory impairment or gait and balance instability. This section highlights the salient age-related changes associated with falling, along with nursing interventions directed at modifying the impact of these changes to prevent falling. Normal age-related changes in organ function can contribute to an intrinsic risk for falling (Tideiksaar, 2005). Overall, most published research on falls and falling pertains to determining fall risk. There are clearly identified antecedents (e.g., diseases such as stroke, delirium, dementia, or urinary incontinence) that can lead to falls (Box 12–3), but many individuals with these disease-related risk factors do not fall. Thus fall risk is not determined solely on the basis of the number and kind of diseases but also on how these risk factors influence an older adult’s functional ability, specifically in the areas of mobility, transferring, and negotiating within the environment. As mentioned, risk for falling is different from actual intrinsic or extrinsic causes of falling. In the latter case, a fall has actually occurred and is the result of either intrinsic disease, extrinsic causes in the environment, or a combination of the two. These falls are likely to occur among those deemed at “risk for falling.” The workup seeks to identify the underlying cause so that it can be treated, thus ultimately preventing or reducing recurrent falling. One aim of fall management is the reduction of risk factors to promote safety while still respecting client autonomy. Because falling is individually determined and not always preventable or predictable, it is important to avoid classifying clients according to the clinician’s perception of their risk for falling (i.e., high risk versus low risk). As previously discussed, falling does not necessarily occur among individuals who are deemed at greatest risk. The effect of functional ability has significance as it relates to older individuals who fall. Research has shown that the individual with frailty and physical functional limitations is at greatest risk for falling (Tideiksaar, 2005). Intrinsic risk for falling refers to the combined effect of normal age-related changes and concurrent disease. The most salient observations for intrinsic risk relate to gait, balance, stability, and cognition. This requires the gerontologic nurse to observe and analyze older individuals’ gait and balance and determine whether impairment exists. Measurement tools have been developed to rate both gait and balance. These tools identify key components of gait such as step length and height, step symmetry, and path. Important areas of balance assessment include sitting and standing balance, turning, and the ability to sit without loss of balance. The Tinetti Gait and Tinetti Balance instruments are measurement tools that quantitatively score gait and balance. These tools have been tested through clinical research and hold acceptable validity and reliability ratings (Tinetti, 1986). Before managing gait or balance impairments with assistive aids or physical therapy, older individuals require medical workups for treatable causes of gait and balance abnormalities (Table 12–1). TABLE 12–1 TREATABLE CAUSES OF GAIT AND BALANCE ABNORMALITIES The modification of environmental risk factors is also critical for fall prevention. Environmental hazards are those that contribute to accidental falls. Research has found that about 30% of falls can be prevented through environmental modification (Warde, 1997). The key areas that require evaluation for safety are steps, floor surfaces, edges and curbs, lighting, and grab rails; nursing interventions are directed at environmental assessment of the indoor living space in these key areas. Whenever possible, steps that are uneven should be repaired or at least have a sturdy handrail to hold onto for support. Floor surfaces should have low-pile carpeting in good repair. Tears should be sewn to prevent shoe heels from becoming caught. Throw rugs should be eliminated because they are a tripping hazard. Curbs and cement landing surfaces should be painted with a contrasting color to outline edges. Lighting should be adequate in high-traffic and dimly lit areas. On a more global scale, a community effort to notify the local Housing Commission of areas needing improvement is an important step in the design of future homes that are safe for older adults. The most commonly cited place where falls occur in the home is the last step of a staircase. The last step is a problem area primarily because of visual changes or functional impairment. Handrails should be present on both sides of a staircase or series of steps. The handrail typically ends at the second to last step; if a person descending the stairs is using the handrail as a guide for the landing surface, it will place the individual at the second to last step. Interventions to correct this include educating clients about this situation, teaching individuals to count the steps (i.e., keeping a mental tally of the number of steps ascending or descending), and reinstalling handrails that meet individuals’ needs. Another problematic area on the staircase is an unevenness of steps (Fig. 12–1). Observation and correction of this phenomenon may be the first step toward fall prevention in the home. A small percentage of older individuals who fall are at the greatest risk for serious physical injury (Box 12–4). It is vital for the gerontologic nurse to identify these individuals because they possess intrinsic risk factors that can be identified and often modified to prevent serious injury. Additionally, recognition and treatment of these individuals are part of the gerontologic nurse’s role in preventing foreseeable accidents. Serious injuries such as hip fractures, head trauma, and internal bleeding affect only a relatively small percentage of older individuals who fall. Although falls are the leading cause of hip fractures, only about 5% to 6% of older individuals who fall sustain them (CDC, 2004). There is a high mortality rate associated with hip fractures, and the cost of their treatment places great economic strain on society for rehabilitation and other ancillary services (Liporace et al, 2005). Behavioral modification is a broad term applied to interventions that alter behavior to effect positive outcomes. The gerontologic nurse is in a pivotal position to educate older individuals, especially those at risk for serious injury from falling, about fall prevention measures. Older individuals’ knowledge base and receptivity to changing behavior are important aspects for the gerontologic nurse to assess before initiating a teaching program. Specific teaching points will vary individually, but general guidelines for fall prevention and home safety can be illustrated through a pictorial display of high-risk environmental hazards or by issuing a handout with teaching points. As they relate to those conditions most likely to result in serious injury, specific interventions can be reinforced (Table 12–2). TABLE 12–2 BEHAVIORAL INTERVENTIONS TO PREVENT SERIOUS INJURY Falling occurs when persons are upright and walking, termed bipedal or ambulatory, or when they are sitting or lying down, termed nonbipedal. Falls may also be considered serious or nonserious, depending on the consequences for clients. Individuals who fall but not to the lowest level (the ground) and those who catch themselves are considered to be experiencing “near falls”; those who actually fall to the ground are experiencing true falls. Falling can be classified according to the cause of the fall (intrinsic, extrinsic, or multifactorial), frequency of falling, and the timing of falling in relation to other diseases. Most falls in the older adult are multifactorial in etiology, that is, a combination of both intrinsic and extrinsic factors. Because so many different circumstances lead to falls in older adults, it is important to determine the type of fall according to a classification system (Box 12–5). Thus classifications of falls will often aid in determining the underlying causes of the falls. Box 12–6 illustrates the risk factors associated with the various types of falls. It is important to note that individuals can experience any one of these types of falls singularly or in combination. If an older resident experiences a premonitory fall on one occasion, the next fall may be from a different cause altogether. Because falls are often unpredictable and therefore not always preventable, it behooves the clinician to start the evaluation with the goal of identifying and managing those falls that are treatable. The incidence of fall-related injuries spans from trivial trauma, such as skin tears and sprains, to serious injury, such as hip fractures, internal bleeding, or subdural hematomas. Each year thousands of older Americans fall at home. Many of them are seriously injured, and some are disabled. In 2001 more than 11,500 people older than 65 died because of falls (CDC, 2004). Overall the rate of serious injury is low; from 5% to 6% of falls result in hip fractures (Nevitt & Cummings, 1994). Research investigations have found that cognitive impairment, gait and balance impairment, low body mass index, and at least two chronic conditions were factors independently associated with serious injury during a fall (Tinetti, McAvay, & Claus, 1996). Among older adults most injuries caused by falling are considered minor. Perhaps because of the low incidence of serious injury, older individuals often do not perceive falling to be a problem that warrants a report or a medical evaluation. Older individuals who fall may or may not experience psychologic trauma after the fall. Many factors influence the development of postfall trauma, including personality, depression, anxiety, and stress-related syndromes. Overall, little research has been done to elucidate the incidence, prevalence, and occurrence of postfall psychologic trauma. One significant consequence of falling may be fear of falling again or fear of being able to get up independently after a fall. Both these conditions have been researched more extensively than other psychologic trauma associated with the postfall period. However, the fear is not limited to those who fall; it has also been reported among nonfallers (Howland et al, 1998). Fear of falling appears to occur variably in the older adult population. One study found that the majority of a sample of community-dwelling older adults expressed no fear of falling (Arfken et al, 1994). In still other community-based research of older adults, fear of falling existed in both those who had fallen and in those who had not and was evenly distributed between the groups (Gray-Miceli, 1997). Some research has shown that if older persons express a fear of falling, they may avoid activities (Vellas, Wayne, Romero, et al, 1997; Tideiksaar, 2005) and become physically dependent (Burker et al, 1995). One researcher found that chronic dizziness is strongly associated with a fear of falling (Franzoni et al, 1994). The gerontologic nurse’s role is to determine whether fear of falling or other psychologic trauma has occurred after the fall. The best time to elicit this information is during history taking with older individuals who fall. The nurse focuses attention on how confident the older adults are in performing activities that might predispose them to falling. One exception to consider, however, is an older individual who falls when nonambulatory, as in the case of a fall from bed. In this case, confidence may be unaffected during mobility. Possible indicators of a fear of falling are presented in Box 12–7.
