Falls in the Elderly Secondary to Urinary Symptoms

Prevention and Management Update

Prevention and ManageMent UPdate Falls in the Elderly Secondary to Urinary Symptoms Yousef Soliman, MD,1 Richard Meyer, MD,2 Neil Baum, MD3 1Cairo, Egypt; 2Department of Orthopedics, Touro Infirmary, New Orleans, LA; 3Department of Urology, Tulane Medical School, New Orleans, LA Falls and fractures have a significant impact on our patients, their families, and caregivers, and cost the health care system billions of dollars. Each year, millions of adults aged 65 and older fall. Falls can cause moderate to severe injuries, such as hip fractures and head traumas, and can increase the risk of early death. Fortunately, falls are a public health problem that is largely preventable. Because many patients with falls and subsequent fractures have urologic conditions, urologists are positioned to help with the prevention of these significant and costly injuries. This article discusses the epidemiology of falls and fractures, and the urologic comorbidities that increase their risk.

Unfortunately, fewer than half of these people discuss falling with their health care provid1 Among older adults, falls are the leading cause ers. of both fatal and nonfatal injuries. In 2013, 2.5 million nonfatal falls among older adults were treated in emergency departments and more than 734,000 of these patients required hospitalization.2 In 2012, the direct medical costs of falls in the United States were $30 billion when adjusted for inflation.3 Falls are the leading cause of injury-related visits to emergency departments in the United States, as well as the primary etiology of accidental deaths in people over age 65.4,5 The mortality rate for falls increases dramatically with age in both sexes and in all racial and ethnic groups, with falls accounting for 70% of accidental deaths in people aged 75 years and older.4,5 Falls can be indicators of declining health and deteriorating motor function, and they are associated with significant morbidity. More than 90% of hip fractures occur as a result of falls, with most of these fractures occurring in people over age 70 years.4,5 One-third of community-dwelling elderly persons, and 60% of nursing home residents, 28 • Vol. 18 No. 1 • 2016 • Reviews in Urology 4004170006_RIU0686.indd 28 05/04/16 3:14 pm Falls in the Elderly Secondary to Urinary Symptoms fall each year.5 From 1992 through 1995, 147 million injury-related visits were made to emergency departments in the United States.6 Falls were the leading cause of external injury, accounting for 24% of these visits.6 Emergency department visits related to falls are most common in children under age 5 years and in railings, lack of grab bars in the bathroom, and clutter on the floor. In older patients, a fall may be a nonspecific presenting sign of many acute illnesses, including pneumonia, urinary tract infection, or myocardial infarction. It may also be the sign of acute exacerbation of a chronic disease.10 In older patients, a fall may be a nonspecific presenting sign of many acute illnesses, including pneumonia, urinary tract infection, or myocardial infarction. adults over age 65 years. Compared with children, elderly persons who fall are 10 times more likely to be hospitalized and 8 times more likely to die as the result of a fall.7 Trauma is the fifth leading cause of death in persons older than age 65 years,4,5 and falls are responsible for 70% of accidental deaths in persons age 75 years and older.4,5 The elderly, who represent 12% of the population, account for 75% of deaths from falls.4,5 Annually, 1800 falls directly result in death.8 Approximately 9500 deaths in older Americans are associated with falls each year.9 Benign Prostatic Hyperplasia and Overactive Bladder Falls do not occur de novo and people do not fall just because they age. Often, more than one underlying comorbid condition or risk factor is involved in a fall. As the number of risk factors rises, so does the possibility of falling. Many falls are linked to a person’s physical condition or a medical problem, such as arthritis, benign prostatic hyperplasia (BPH), or overactive bladder (OAB). Other causes include safety hazards in the person’s home or community environment; examples include a slick floor or a poorly lit stairway, loose rugs, lack of stair Medication There are multiple medications that can contribute to falls. The leading medication culprits are psychotropic (especially benzodiazepines, antidepressants, and antipsychotics), blood pressure-lowering drugs, and anticonvulsants.11 Sedative medication, including hypnotics, may impair coordination and cause falls.12 There is a particular risk of falls in agitated patients with cognitive impairment. Medications that cause orthostatic hypotension can result in falls. Examples of medica- Major injuries, including head trauma, soft tissue injuries, fractures, and dislocations, occur in 5% to 15% of falls.14 Fractures account for 75% of serious injuries, with hip fractures occurring in 1% to 2% of falls.14 In 1996, more than 250,000 older Americans suffered fractured hips, at a cost in excess of $10 billion. More than 90% of hip fractures are associated with falls, and most of these fractures occur in persons over age 70 years.11 Hip fracture is the leading fall-related injury that results in hospitalization, which is often prolonged and costly.15 Lower Urinary Tract Symptoms Lower urinary tract symptoms (LUTS) represent a cluster of highly prevalent chronic urinary disorders that occur among 15% to 60% of men over age 40.16,17 The prevalence increases sharply with age.1719 The most common etiologies for chronic LUTS are BPH and OAB, conditions that collectively affect Medications that cause orthostatic hypotension can result in falls. tions causing orthostatic hypotension include the following13: • Diuretics (can cause dehydration and may cause urgency and falls) • Vasodilators (including calcium channel blockers and nitrates) • Angiotensin-converting enzyme inhibitors • α-blockers • Phenothiazines • Tricyclic antidepressants • Levodopa • Bromocriptine • β-blockers • Insulin tens of millions of older men and women.16,20 BPH affects 70% of men aged 75 or older; 42% describe symptoms consistent with OAB.20 Both BPH and OAB are associated with nocturia, which is often the prevailing factor leading to nighttime falls and fractures. The most common etiologies of falls are listed in Table 1.16-20 Nearly one in four communitydwelling men over age 65 have one or more falls each year.21,22 A substantial proportion of these individuals will have serious injury, pain, depression, and other comorbidities.

Published reports have suggested that urgency, frequency, nocturia, and urinary incontinence are associated with an increased likelihood of falls in older adults.24,25 The mechanistic inference is that these symptoms may force abrupt, unexpected alterations of daily physical routines and compel affected individuals to engage in potentially senior citizens, urinary frequency or incontinence was reported more frequently among fallers than nonfallers, and were among six factors that predicted the risk of falls.28 In addition to urgency and urgency incontinence, stress urinary incontinence and daytime or nocturnal urinary frequency have also been associated with increased risk of falls.29,30 Data from a longitudinal health-screening program of 1508 ambulatory older men and women revealed that nocturia episodes at least twice nightly signifi- … these symptoms may force abrupt, unexpected alterations of daily physical routines and compel affected individuals to engage in potentially risky behaviors, such as arising several times a night to urinate. risky behaviors, such as arising several times a night to urinate. Thus, if this association is confirmed, urinary symptoms may be a potential target for preventive interventions to reduce fall risk in communitydwelling men and women. In one US study of 6049 community-based women, one or more episodes per week of urgency incontinence were independently associated with fall risk.26 Similar findings from Finland were reported for 1016 older home-dwelling adults with both urinary urgency and urinary incontinence.27 In a prospective study of 405 Taiwanese community cantly increased risk of falls, and that risk increased dramatically in those reporting more than three episodes.31 Prevention Many clinical commissioning groups now have multidisciplinary fall teams that can assess and treat those at risk, but we believe that members of the primary care team should also contribute to the fall prevention strategy. Patient care providers and local communities can also play a role in prevention of falls.32 One study found that encouraging patients to manage their own exercise-based fall prevention program improves compliance, and that physiotherapists should become part of the fall prevention program.33 The most effective prevention of falls involves a multidisciplinary, holistic, and patient-specific approach. Measures should take into account the person’s medical conditions, social circumstances, and psychologic factors. Moreover, proactive prevention of falls could include increasing exercise and physical activity, improving management of any medical conditions, reviewing medication, and changing adverse environmental factors. Examples of prevention include the following: 1. Adapting the home: stairs, bathrooms, and kitchens can present hazards for older people; even if changes don’t need to be made immediately, perform an annual safety review in order to make necessary updates as individual needs change. 2. Exercising and training: falls are serious in older people— they often result in fractures that can lead to disability, further health problems, or even death; safety precautions are important, but so are exercises that can improve balance and strength. An effective screening tool for urologists who care for patients at risk for falls consists of five items: (1) assessing previous falls, (2) agitation, (3) visual impairment, (4) toileting frequency, and (5) transfer/mobility problems, using the Barthel Index Scoring System. Each item is scored with 1 point for a “yes” or 0 points for a “no” response to questions related to the above five items; loadings 30 • Vol. 18 No. 1 • 2016 • Reviews in Urology 4004170006_RIU0686.indd 30 05/04/16 3:14 pm Falls in the Elderly Secondary to Urinary Symptoms are not used, giving each risk equal value. A score of  2 is used to determine a high risk of falling.34 Communication With Colleagues to Prevent Falls and Fractures Patients who are at risk for falls and fractures with urologic conditions, such as BPH, incontinence, and OAB, will need more attention inform the primary care physician of concerns and alert him or her in the referral letter that this risk has been identified. If a patient has decreased bone mineral density, which is determined by bone densitometry scanning, it is prudent to be certain that the patient is taking supplemental calcium and vitamin D and to refer the patient to a physical therapist for instructions on weight-bearing exercises.

Other colleagues include the primary care physician, the orthopedist, the physical therapist, and the patient’s pharmacist. When urologists have provided care for a patient who is at risk of falls and fractures, it is helpful to Finally, if there is a question of decrease in the patient’s vision, the urologist should suggest that the patient have his or her eyes checked by an eye doctor at least annually and update his or her eyeglass prescription to maximize vision. Patients should consider getting a pair of glasses with single vision distance lenses for some activities, such as walking outside. Conclusions Falls and fractures are, for the most part, preventable. Physicians need to be aware of the morbidity and mortality associated with falls and fractures. Many patients who experience falls and subsequent fractures have associated urologic comorbidities. Urologists need to help patients who are at risk for falls and fractures by making every effort to bring these risk factors to the attention of patients and care givers, and find ways to help prevent falls and fractures.
