Falls Flashcards
What is a fall
World Health Organization defines a fall as:
- “An event which results in a person coming to rest inadvertently on the ground or floor or other lower level”.
- There’s a challenge to an individual’s balance or strength > Ability to stay upright
Significance of falls
• Falls is a quality indicator for residential care: four selected quality indicators for home and residential care settings, specifically signs and symptoms of depression, pain, pressure ulcers and falls
• On an individual level falls are very significant for the elder, it impacts ADLs
• On a systemic level, falls are used as a quality indicator; once someone falls the hospital has to pay
• Falls are the #1 reason for hospitalizations of older people (81%)
• They can be quite striking; extremely fragile skin and takes a long time to heal
• Falls are also the top reason for injury among seniors seen in the ER
• Falls accounted for 60% of all reported ER visits among seniors, with an estimated 20% admitted to
the hospital
Epidemiology of fall-related injuries in older adults
Hip fractures • 23,000/yr in Canada • 25% die within one year • 50% lose independence • 95% caused by falls
Wrist fractures
• Similar in frequency to hip fractures
• 90% caused by falls
Traumatic brain injuries • 20,000/yr in Canda • 80% caused by falls • 41% of fall deaths • 2-fold increased in past decade
Spinal cord injuries
• 1,800/yr in Canada
• 50% caused by falls
How are falls studied?
- Examining the velocity of falling and how people may fall in certain ways that would lead to injuries of hips and wrists
- Recording how well people recover fro various movement patterns
- Can measure effectiveness of intervention in a controlled setting
Types of falls
Common types of falls
• Slips and trips
• Falls on stairs
• Falls from furniture
People fall when they are • Turning • Incorrect weight shifting • Transferring • Forward walking • Standing quietly • Sitting down
Etiology of falls
- Falls result from complex interactions between intrinsic and extrinsic factors
- Physiological
- Environmental
- Behavioural
Intrinsic risk factors for falls
- Advanced age
- Previous falls
- Muscle weakness
- Gait and balance problems
- Poor vision
- Postural hypotension
- Fear of falling
- Chronic conditions; arthritis, stroke, incontinence, diabetes, Parkinson’s, dementia
Extrinsic risk factors for falls
- Lack of stair handrails
- Poor stair design
- Lack of bathroom grab bars
- Dim lighting or glare
- Obstacles and tripping hazards
- Slippery or uneven surfaces
- Psychoactive medications
- Improper use of assistive devices
GOAL; reduce modifiable risk factors
Modifiable risk factors for falls
Risk factor (relative risk) • Muscle weakness (4.4x) • Gait and balance problems (2.9x) • Vision problems (2.5x) • Psychoactive medications (1.7x)
Multifactorial interventions to address and prevent falls is best
How do drugs contribute to falls?
- Decreased mental alertness
- Impaired cognitive function and/or judgment
- Impaired postural stability
- Hypotension
- Postural Hypotension
- Arrhythmias
Risk factors for significant injury due to falling
1) Current use of anticoagulants
- Slow down rate of clotting in blood to prevent heart attack
- But makes it slower for blood to stop bleeding so increased risk of injury
2) Patients wth osteoporosis
3) Post surgical patients
- Use of ansthesia or anaglesic
4) History of falls
Osteoporosis and falls
- A bone disease that occurs when the body loses too much bone, makes too little bone, or both
- As a result, bones become weak and may break from a fall
Risk factors:
• Older women are much more likely to develop osteoporosis than are men.
• Advanced age. The older you get, the greater your risk of osteoporosis.
• Race. You’re at greatest risk if white or Asian.
• Family history. Having a parent or sibling with osteoporosis
• Body frame size. Men and women who have small body frames tend to have a higher risk because they might have less bone mass to draw from as they age.
Prevention of falls in OAs; clinical practice guidelines
- Screen for Falls or Risk for Falling
- The screening for falls and risk for falling is aimed at preventing or reducing fall risk. - Evaluation of Gait and Balance
- Gait and balance deficits should be evaluated in older individuals reporting a single fall as a screen.
- E.g. Timed Up and Go Test - Determination of Multifactorial Fall Risk.
- A multifactorial fall risk assessment can reveal the factors that put an older adult at risk of falling and can help identify the most appropriate interventions. - Initiate Multifactorial or Multicomponent Interventions
- To Address Identified Risk(s) and Prevent Falls
Multifactorial approach to falls interventions
1) Minimize medications
2) Provide individually tailored exercise program
3) Treat vision impairment
4) Manage postural hypotension
5) Manage heart rate and rhythm abnormalities
6) Supplement vitamin D
7) Manage foot and footwear problems
8) Modify the home environment
9) Provide education and information
Environmental: clinical setting falls risks
- Cluttered path
- Spill on floor
- Cords
- Lighting too bright or too low
- Table far away from bed
- Bed at high awkward height
- Brake not one equipment and/or table or bed
- Sheets or blanket hanging off the bed loosely
