Falls in older adults are a significant cause of morbidity and mortality and are a major class of preventable injuries. Falling is one of the most common accidents that cause a loss in the quality of life for older adults, and is usually precipitated by a loss of balance and weakness in the legs. [1] [2] The cause of falling in old age is often multifactorial and may require a multidisciplinary approach both to treat any injuries sustained and to prevent future falls. [3] Falls include dropping from a standing position or from exposed positions such as those on ladders or stepladders. The severity of injury is generally related to the height of the fall. The state of the ground surface onto which the victim falls is also important, harder surfaces causing more severe injury. Falls can be prevented by ensuring that carpets are tacked down, that objects like electric cords are not in one's path, that hearing and vision are optimized, dizziness is minimized, alcohol intake is moderated and that shoes have low heels or rubber soles. [4]
A review of clinical trial evidence by the European Food Safety Authority led to a recommendation that people over the age of 60 years should supplement the diet with vitamin D to reduce the risk of falling and bone fractures. [5] Falls are an important aspect of geriatric medicine.
Other definitions are more inclusive and do not exclude "major intrinsic events" as a fall. [6] Falls are of concern within medical treatment facilities. Fall prevention is usually a priority in healthcare settings. [7]
A 2006 review of literature identified the need for standardization of falls taxonomy due to the variation within research. [8] The Prevention of Falls Network Europe (ProFane) taxonomy for the definition and reporting of falls aimed at mitigating this problem. [9] ProFane recommended that a fall be defined as "an unexpected event in which the participants come to rest on the ground, floor, or lower level." [9] The ProFane taxonomy is currently used as a framework to appraise falls-related research studies in Cochrane Systematic Reviews. [10] [11] [12]
Falls are often caused by a number of factors. The faller may live with many risk factors for falling and only have problems when another factor appears. As such, management is often tailored to treating the factor that caused the fall, rather than all of the risk factors a patient has for falling. Risk factors may be grouped into intrinsic factors, such as existence of a specific ailment or disease. External or extrinsic factors include the environment and the way in which it may encourage or deter accidental falls. Such factors as lighting and illumination, personal aid equipment and floor traction are all important in fall prevention. [13]
When assessing a person who has fallen, an eyewitness account of the incident is helpful. However the person who fell may have been temporarily unconscious, and may not be able to give an accurate description of the fall. In practice, these eyewitness accounts are often unavailable.
The relationship between the person at risk of falling and their environment is important for determining the risk falls and taking measures to prevent falls. An assessment with an occupational therapist may be helpful to determine an appropriate rehabilitation plan to prevent falls by taking into consideration both the person and their living environment. [14] [15] A large body of evidence shows that efforts to include exercise decrease the risk of falls, [16] [17] and yet the fear of falling can lead to a decrease in participation in physical exercise. [14]
Possible interventions to prevent falls include:
Improvements to the person's environment such as their home or workplace may help to reduce the risk of falling. [14] [18]
Cognitive behavioral therapy (CBT) has been suggested as a prevention approach to improve confidence and help older people reduce the fear of falling. [25] There is moderate evidence to suggest that this technique can be effective at reducing the fear of falling for up to and beyond 6 months. [25] CBT appears to have a positive effect on activity avoidance and risk of depression; however, it is not clear whether CBT reduces the incidence of falls in older people. [25]
People who are hospitalized are at risk for falling. A randomized trial showed that use of a tool kit reduced falls in hospitals. Nurses complete a valid fall risk assessment scale. From that, a software package develops customized fall prevention interventions to address patients' specific determinants of fall risk. The kit also has bed posters with brief text and an accompanying icon, patient education handouts, and plans of care, all communicating patient-specific alerts to key stakeholders. [27]
The American Geriatrics Society and the British Geriatrics Society recommend that all older adults should be screened for "falls in the past year". Fall history is the strongest risk factor associated with subsequent falls. [28] Older people who have experienced at least one fall in the last 6 months, or who believe that they may fall in the coming months, should be evaluated with the aim of reducing their risk of recurrent falls. [29]
Many health institutions in the USA have developed screening questionnaires. Enquiry includes difficulty with walking and balance, medication use to help with sleep/mood, loss of sensation in feet, vision problems, fear of falling, and use of assistive devices for walking.
Older adults who report falls should be asked about their circumstances and frequency to assess risks from gait and balance which may be compromised. A clinician performs a fall risk assessment, to include history, physical exam, functional capability, and environment. [30]
Prevention approaches that target the whole population of older people in a particular area are defined as population-based interventions. These include policies put in place by governments for vitamin supplementation, maintenance programs to reduce risks in public spaces and homes, public health programs offering exercise classes and sharing resources widely (not just to people identified as being high risk), improving access to gyms (for example allowing seniors to access a gym for free if over a certain age). [31] The evidence supporting population-based interventions is weak. It is not clear if population-based interventions that improve access to medications or nutritional program are effective. [31]
The incidence of falls increases progressively with age. According to the existing scientific literature, around one-third of the elderly population experience one or more falls each year, while 10% experience multiple falls annually. For people over 80, the annual incidence of falls can reach 50%. [32] [33] [34] [35] [36]
Researchers have tried to create a consensual definition of a fall since the 1980s. Tinneti et al. defined a fall as "an event which results in a person coming to rest unintentionally on the ground or other lower level, not as a result of a major intrinsic event (such as a stroke) or overwhelming hazard." [37]
The health care impact and costs of falls in older adults are significantly rising all over the world. The cost of falls is categorized into two aspects: direct cost and indirect cost.
Direct costs are what patients and insurance companies pay for treating fall-related injuries. This includes fees for the hospital and nursing home, doctors and other professional services, rehabilitation, community-based services, use of medical equipment, prescription drugs, changes made to home and insurance processing.
Indirect costs include the loss of productivity of family caregivers and long-term effects of fall-related injuries such as disability, dependence on others and reduced quality of life.
In the United States alone, the total cost of falling injuries for people 65 and older was $31 billion in 2015. The costs covered millions of hospital emergency room visits for non-fatal injuries and more than 800,000 hospitalizations. By 2030, the annual number of falling injuries is expected to be 74 million older adults. [38]
Furthermore, a 2012 systematic review has demonstrated that performing dual-task tests (for example, combining a walking task with a counting task) may help in predicting which people are at an increased risk of a fall. [3]
Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk.
Dementia is a syndrome associated with many neurodegenerative diseases, characterized by a general decline in cognitive abilities that affects a person's ability to perform everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Dementia ultimately has a significant effect on the individual, their caregivers, and their social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than might be caused by the normal aging process.
Asthma is a common long-term inflammatory disease of the airways of the lungs. Asthma occurs when allergens, pollen, dust, or other particles, are inhaled into the lungs, causing the bronchioles to constrict and produce mucus, which then restricts oxygen flow to the alveoli. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. These may occur a few times a day or a few times per week. Depending on the person, asthma symptoms may become worse at night or with exercise.
Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms itself. It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a major cause of premature death worldwide.
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. Common symptoms include increased thirst, frequent urination, fatigue and unexplained weight loss. Other symptoms include increased hunger, having a sensation of pins and needles, and sores (wounds) that heal slowly. Symptoms often develop slowly. Long-term complications from high blood sugar include heart disease, stroke, diabetic retinopathy, which can result in blindness, kidney failure, and poor blood flow in the lower-limbs, which may lead to amputations. The sudden onset of hyperosmolar hyperglycemic state may occur; however, ketoacidosis is uncommon.
Delirium is a specific state of acute confusion attributable to the direct physiological consequence of a medical condition, effects of a psychoactive substance, or multiple causes, which usually develops over the course of hours to days. As a syndrome, delirium presents with disturbances in attention, awareness, and higher-order cognition. People with delirium may experience other neuropsychiatric disturbances including changes in psychomotor activity, disrupted sleep-wake cycle, emotional disturbances, disturbances of consciousness, or, altered state of consciousness, as well as perceptual disturbances, although these features are not required for diagnosis.
Smoking cessation, usually called quitting smoking or stopping smoking, is the process of discontinuing tobacco smoking. Tobacco smoke contains nicotine, which is addictive and can cause dependence. As a result, nicotine withdrawal often makes the process of quitting difficult.
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone. It is believed to be the fourth leading cause of disability in the world, affecting 1 in 7 adults in the United States alone. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs, the knee and hip joints, and the joints of the neck and lower back. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are affected.
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis.
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. Most infections are viral in nature, and in other instances, the cause is bacterial. URTIs can also be fungal or helminthic in origin, but these are less common.
Low back pain or lumbago is a common disorder involving the muscles, nerves, and bones of the back, in between the lower edge of the ribs and the lower fold of the buttocks. Pain can vary from a dull constant ache to a sudden sharp feeling. Low back pain may be classified by duration as acute, sub-chronic, or chronic. The condition may be further classified by the underlying cause as either mechanical, non-mechanical, or referred pain. The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people recovered by six weeks.
Pressure ulcers, also known as pressure sores, bed sores or pressure injuries, are localised damage to the skin and/or underlying tissue that usually occur over a bony prominence as a result of usually long-term pressure, or pressure in combination with shear or friction. The most common sites are the skin overlying the sacrum, coccyx, heels, and hips, though other sites can be affected, such as the elbows, knees, ankles, back of shoulders, or the back of the cranium.
A hip fracture is a break that occurs in the upper part of the femur, at the femoral neck or (rarely) the femoral head. Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. Usually the person cannot walk.
Respiratory tract infections (RTIs) are infectious diseases involving the lower or upper respiratory tract. An infection of this type usually is further classified as an upper respiratory tract infection or a lower respiratory tract infection. Lower respiratory infections, such as pneumonia, tend to be far more severe than upper respiratory infections, such as the common cold.
Fall prevention includes any action taken to help reduce the number of accidental falls suffered by susceptible individuals, such as the elderly (idiopathic) and people with neurological or orthopedic indications.
A hip protector is a specialized form of pants or underwear containing pads along the outside of each hip/leg, designed to prevent hip fractures following a fall. Recent developments include the use of double-sided adhesive films that are breathable and more comfortable to wear than specialised pants. The adhesive films are safer because they can be worn in the bath or shower, or when toileting. Hip protectors are most commonly used in elderly individuals who have a high risk of falls and hip fractures.
Falling is the action of a person or animal losing stability and ending up in a lower position, often on the ground. It is the second-leading cause of accidental death worldwide and a major cause of personal injury, especially for the elderly. Falls in older adults are a major class of preventable injuries. Construction workers, electricians, miners, and painters are occupations with high rates of fall injuries.
Prevention of type 2 diabetes can be achieved with both lifestyle changes and use of medication. The American Diabetes Association categorizes people with prediabetes, who have glycemic levels higher than normal but do not meet criteria for diabetes, as a high-risk group. Without intervention, people with prediabetes progress to type 2 diabetes with a 5% to 10% rate. Diabetes prevention is achieved through weight loss and increased physical activity, which can reduce the risk of diabetes by 50% to 60%.
Hypertension is managed using lifestyle modification and antihypertensive medications. Hypertension is usually treated to achieve a blood pressure of below 140/90 mmHg to 160/100 mmHg. According to one 2003 review, reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21% and reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease.
