An accident is an unintended, normally unwanted event that was not directly caused by humans. The term accident implies that nobody should be blamed , but the event may have been caused by unrecognized or unaddressed risks . Most researchers who study unintentional injury avoid using the term accident and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm , its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however, English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry.
76-709: Physical examples of accidents include unintended motor vehicle collisions, tongue biting while eating, electric shock by accidentally touching bare electric wire, drowning, falls , being injured by touching something sharp or hot, or bumping into something while walking. Non-physical examples are unintentionally revealing a secret or otherwise saying something incorrectly, accidental deletion of data, or forgetting an appointment. It has been argued by some critics that vehicle collisions are not truly accidents, given that they are mostly caused by preventable causes such as drunk driving and intentionally driving too fast, and as such should not be referred to as accidents . Since 1994,
152-489: A stroke have higher fall rates. Approximately 30% fall at least once a year and 15% fall twice or more. Risk factors for falls in stroke survivors are: Most people with Parkinson's disease (PD) fall and many experience recurrent falls. A study reported that over 50% of persons with PD fell recurrently. Direct and indirect causes of falls in patients with PD: There is a high prevalence of falls among persons with multiple sclerosis (MS), with approximately 50% reporting

The United States also collects statistically valid injury data (sampled from 100 hospitals) through the National Electronic Injury Surveillance System administered by
304-539: A 30% chance of falling each year, making fall-related injuries the leading cause of accident-related death for this demographic. Current approaches to fall prevention are problematic because even though awareness is high among professionals that work with seniors and fall prevention activities are pervasive among community living establishments, fall death rates among older adults have more than doubled. The challenges are believed to be three-fold. First, insufficient evidence exists that any fall risk screening instrument
380-451: A 54% reduction in falls. After the age of 50, adults experience a decrease in muscle mass ( sarcopenia ) by approximately 2% every year. A systematic review concluded that resistance training can slow down the rate of loss in muscle mass and strength. It has been recommended that older adults participate in resistance training two to three times a week to weaken the effects of sarcopenia. Assistive technology can also be applied, although it

Environmental risk arises from environmental hazards or environmental issues . In the environmental context, risk is defined as "The chance of harmful effects to human health or to ecological systems". Environmental risk assessment aims to assess the effects of stressors, often chemicals, on
608-739: A couple of studies that have found that an increase in muscle strength will also strengthen an older person’s balance due to their nervous and muscular systems are not as fully functional. One of these exercises is Tai-Chi, which not only improves balance, but also quality of life, flexibility, and strength. Environmental modifications, like improving lighting, removing tripping hazards, and repairing uneven surfaces, further contribute to fall prevention. Addressing these hazards within everyday settings helps make interventions practical and accessible, empowering older adults to actively engage in improving their stability and reducing fall risks. Challenges such as transportation barriers, gaps in care continuity, and

The trial also showed a significant improvement in walking speed which is a risk factor for morbidity, hospitalization, and disability. A meaningful change in walking speed is defined as an increase of 0.05 meters per second. The Resistance and Balance training group showed an improvement of 0.37 meters per second, contrasting
760-504: A fall risk. Physical and Occupational therapist use similar exercises to treat fall risk patients. Structured exercise programs allow seniors to reduce fall risk and generally increase quality of life. Proprioception (the ability to sense where the body is in a space) increases and muscular strength and endurance allow for older adults to help themselves if a fall where to occur. Another type of exercise that has been seen to be beneficial in decreasing fall risk, specifically in older women,
836-496: A fall within the past six months. About 30% of those individuals report falling multiple times. Studies suggest that men are twice as likely to fall as women. Common causes of falls in dementia include: Basophobia is a term used in many circumstances to describe the fear of falling in either normal or special situations. It refers to uncomfortable sensations that may be experienced by older people. These sensations can include lower-body weakness or loss of balance, which can induce

#1732765909046912-488: A frightening sensation of falling that can lead to serious and potentially fatal injuries. Fear of falling has become a serious and common concern among older adults and impedes on one’s participation in daily activities. Negative consequences can result to impaired mobility, loss of independence, and a decreased quality of life. The state of an individual’s quality of life is important when regarding both positive and negative elements that may prohibit them from living life to
988-725: A high-cost physical therapist or longer-term wellness activity provided in a low-cost group setting. Neither arrangement is optimum in preventing falls over a large population, especially as these evidence-based physical exercise programs have limited effectiveness (approximately 25%). Even multifactorial interventions, which include extensive physical exercise , medication adjustment, and environmental modification only lower fall risk by 31% after 12 months, and by 21% after 24 months. Questions around effectiveness of current approaches (physical exercise and multifactorial interventions) have been found in multiple settings, including long-term care facilities and hospitals. The final challenge
1064-511: A higher prevalence of falls. Accidents are the most common cause of falls involving healthy adults, which may be the result of tripping on stairs, improper footwear, dark surroundings, slippery surfaces, uneven ground, or lack of exercise. Studies suggest that women are more prone to falling than men in all age groups. The most common injuries among younger patients occur in the hands, wrists, knees, and ankles. The home environment can present many hazards. Common places for injurious falls include
1140-405: A highly quantified way. The technique is usually referred to as probabilistic risk assessment (PRA). See WASH-1400 for an example of this approach. The incidence rate can also be reduced due to the provision of better occupational health and safety programmes. Security is freedom from, or resilience against, potential harm caused by others. A security risk is "any event that could result in
1216-608: A history of falls and 33.0% to 46.0% among those who do not have a history of falling. Basophobia and its related activity avoidance among the elderly may lead to a vicious cycle of falls and functional impairment. It is important to be aware of this when working with the older population and recommending preventive strategies. Many strategies include the participation in community and home-based exercise programs, cognitive behavioral therapy, yoga, meditation, and practicing good sleep hygiene. Restriction of these activities could lead to muscle weakness, postural instability, deconditioning and
1292-420: A history of falls. Beers Criteria is a list of medications that are potentially inappropriate for use in the elderly and some of them increase the risk of falls. Falls are well known amongst community-dwelling individuals ages 65 and older. The risk of fall-related incidents nearly doubles when individuals are institutionalized. The impact on different falls in certain situation of fall prevention programs on

Risk management refers to a systematic approach to managing risks, and sometimes to the profession that does this. A general definition is that risk management consists of "coordinated activities to direct and control an organization with regard to risk". ISO 31000 ,
1444-437: A lower fall risk. Due to pilates showing positive effects on balance, leg strength, and mental well-being, this allows older adults to be more physically and mentally strong. These factors can allow for elderly people to be more confident to decrease their fall risk. Studies have also found VR on Xbox Kinect is beneficial for an elderly persons’ balance and their fear of falling. A study conducted on 60 older individuals living in
1520-486: A nursing home participated in VR exercises on an Xbox Kinect for 30-45 minutes every week for 6 weeks. Once the study was completed, those in the intervention group were found to have better balance as well as a decreased score of fear of falling. Other forms of training, such as aerobic, anaerobic, and proprioceptive exercises can also be used to increase balance to lower the risk of falls in the elderly population. There have been
1596-431: A pool of risks including market risk, credit risk, operational risk, interest rate risk, mortality risk, longevity risks, etc. The term "risk" has a long history in insurance and has acquired several specialised definitions, including "the subject-matter of an insurance contract", "an insured peril" as well as the more common "possibility of an event occurring which causes injury or loss".

#17327659090461672-622: A simple summary, defining risk as "the possibility of something bad happening". The International Organization for Standardization (ISO) 31073 provides basic vocabulary to develop common understanding on risk management concepts and terms across different applications. ISO 31073 defines risk as: effect of uncertainty on objectives Note 1: An effect is a deviation from the expected. It can be positive, negative or both, and can address, create or result in opportunities and threats . Note 2: Objectives can have different aspects and categories, and can be applied at different levels. Note 3: Risk
1748-521: A variety of hazards that may result in accidents causing harm to people, property and the environment. In the safety field, risk is typically defined as the "likelihood and severity of hazardous events". Safety risks are controlled using techniques of risk management. A high reliability organisation (HRO) involves complex operations in environments where catastrophic accidents could occur. Examples include aircraft carriers, air traffic control, aerospace and nuclear power stations. Some HROs manage risk in
1824-428: Is adherence . Average adherence in group-based fall prevention exercise programs is around 66%, mostly due to the highly repetitive nature of the programs and the extremely long duration required for noticeable benefits accrue. Adherence to physical therapy can be even lower. When adherence is below 70%, effectiveness of fall prevention physical exercise programs can drop to less than 10%. Practitioners are aware that
1900-485: Is a high agreement on guidelines for fall prevention across clinical practices. These include (but are not limited to): the use of specific tests for gait and balance assessments, multifactorial interventions, medication review, physical exercises, vision and footwear intervention, physiotherapy referral, environment modification, risk stratification, management of osteoporosis and fracture risk, and cardiovascular interventions. Balance of Older adults can be examined through

Health, safety, and environment (HSE) are separate practice areas; however, they are often linked. The reason is typically to do with organizational management structures; however, there are strong links among these disciplines. One of the strongest links is that a single risk event may have impacts in all three areas, albeit over differing timescales. For example,
2052-574: Is a type of training shown to improve the postural system. Resistance training also has a positive impact on older adults. It is shown that it causes a major increase in strength and muscle size. It is important to combine muscle strengthening exercises and balance training together to ensure reduced risks of falls. An older adult should be focusing more on strengthening their legs, hip, and core muscles. Strengthening these muscles will provide them with more stability. These exercises may minimize or reduce physical frailty. The elderly population can benefit
2128-522: Is adequate for predicting falls. While the strongest predictors of fall risk tend to include a history of falls during the past year, gait , and balance abnormalities, existing models show a strong bias and therefore mostly fail to differentiate between adults that are at low risk and high risk of falling. Second, current fall prevention interventions in the United States are limited between short-term individualized therapy provided by
2204-416: Is an individual or collaborative undertaking planned to achieve a specific aim. Project risk is defined as, "an uncertain event or condition that, if it occurs, has a positive or negative effect on a project's objectives". Project risk management aims to increase the likelihood and impact of positive events and decrease the likelihood and impact of negative events in the project. Safety is concerned with

2432-619: Is mostly reactive in case of a fall. Exercise as a single intervention has been shown to prevent falls in community-dwelling older adults. A systematic review suggests that having an exercise regimen that includes challenging balance workouts for three or more hours per week results in a lesser chance of falling. Resistance training has been shown to be beneficial beyond fall prevention, as it also helps improve functional mobility and activities of daily living such as walking endurance, gait speed, and stair climbing. Research explains that this significant increase in performance can be accomplished after

Evidence suggests that pre-discharge home assessments are associated with a reduced risk of falling. Important improvements to prevent falls include handrails and grab bars, which should be easy to grip or grasp and should be near any stairs or change in floor level. Floors should always be flat and level, with no exposed corners or edges. Patterned floors can be dangerous if they create misleading or distorted images of
5396-508: The societal value of comprehensive, community-based fall-prevention interventions. Risk In simple terms, risk is the possibility of something bad happening. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences. Many different definitions have been proposed. One international standard definition of risk
