1 in 3 community-dwelling Canadian seniors experience a fall each year (It is estimated that only 1 in 13 falls are reported) In 1997, falls accounted for 20% of all injury deaths among seniors 56% of all people admitted to hospital with injuries due to falls are over 65 The estimated annual direct costs of falls is $2.4 billion – caring for seniors injured from a fall represents 41% of these costs, or $1 billion Health Canada / Veterans Affairs Canada Falls Prevention Initiative, Fact Sheet No. 6, 2002 FACTS ON FALLS AMONG SENIORS
FALLS IN OLDER ADULT What is a fall? A fall is "an event that results in a person coming to rest inadvertently on the ground or floor or other lower level." This could include an event where the person landed on the ground, tripped on stairs, slipped, or lost his or her balance and hit against an object like a chair or bed. Kellogg International Work Group, 1987; RNAO, 2002, Nursing Best Practice Guideline Prevention.
POST-FALL SYNDROME Fall Loss of Confidence Activity Restriction Loss of Mobility Increased Dependence
“Only frail seniors need to worry about serious falls” SENIOR’S PERSPECTIVES REGARDING FALLS “People will think I’m too old to live by myself if I use a cane” “My home is not a home without the scatter rugs” “My doctor is in charge of my medications” “My home is safe from falls because I can avoid all the hazards”
I dropped something and reached for it. I fell, bumped my head on the night table and rolled on the floor. I can’t get up because of an operation on my knees. I crawled up using my comforter, got onto the bed, fell forward and my nose started to bleed. The next morning, my back hurt, and I had a purple lump on my head. My nephew came over. He was angry because I wasn’t using my cane. He told people in the building to notify him if they see me without my cane. A SENIOR RECOUNTS HIS FALL
WHAT ASSISTIVE DEVICES ARE MEANT TO DO Minimize the effects of many age-related changes: impaired mobility range of motion balance coordination muscular strength endurance Axtell & Yasuda, 1993; Bynum & Rogers, 1987; Tinetti, 1986
The Biomechanical View: Maintaining & improving mobility Increase standing and walking base of support and stability Increase standing and walking base of support and stability Provide proprioreceptive feedback through the handle Provide proprioreceptive feedback through the handle Shift the load on weight-bearing joints to the upper limb Shift the load on weight-bearing joints to the upper limb Provides a visual presence of support and instill confidence during ambulation Provides a visual presence of support and instill confidence during ambulation (R Tideiksaar, 2003) (R Tideiksaar, 2003)
The Psychosocial View: Social support, sense of confidence Canes provide increased confidence for performance of daily activities (Dean & Ross, 1993, Aminzadeh & Edwards, 1997) Canes provide increased confidence for performance of daily activities (Dean & Ross, 1993, Aminzadeh & Edwards, 1997) Individuals hold unique preferences for image and autonomy (Pippin & Fernie, 1997) Individuals hold unique preferences for image and autonomy (Pippin & Fernie, 1997) Device acceptance is dependent on context (Pippin & Fernie, 1997) Device acceptance is dependent on context (Pippin & Fernie, 1997) Habitual versus seasonal patterns of device use (Edwards, et al., 1999) Habitual versus seasonal patterns of device use (Edwards, et al., 1999)
Perceived Importance of risk factors for falls among community dwelling elderly (n=68/52) Braun, 1998 Risk Factor Importance for a fall among general elderly (they fall) Importance for a personal fall (I am likely to fall) Grab bars not present or not in a helpful position 7.7 (2.4) 2.7 (3.3) Handrails not present or poorly positioned 7.7 (2.7) 4.6 (3.4) Coordination or balance problem 8.2 (2.1) 2.7 (3.3) Doing unsafe or risky things 8.0 (2.7) 1.9 (2.5) Sidewalks poorly maintained 8.7 (1.8) 7.2 (2.8)
Older adults estimate standing reach more accurately than bending reach Older adults tend to overestimate reach ability and negate the “safety factor” Greatest overestimation of bending reach ability was observed for the most motor-impaired elderly Robinovitch (1998); Robinovitch & Cronin (1999) SENIOR’S PERSPECTIVES ON THEIR ABILITIES
Possession of Selected Devices Assistive Device Possession Sweden (n=734) (Sonn & Grimby, 1994) Possession Belgium (n=117) (Roelands et al., 2002) Grab bars 15.9%15.9% Walking canes 15.3%59.1% Bath seat 8.2% Free standing lifting pole -26.1% Anti-slip bathmat -67.8%
Mobility aids: Canes WHAT DEVICES ARE WE TALKING ABOUT? Figure 1. Schematic of two types of hip protector (A) worn over clothing and (B) worn within specially designed underwear Hip protectors Bath safety devices
WHY BATHROOM ASSISTIVE DEVICES 10-15% of falls happen in bathroom 73% result in injuries 55% of bathroom falls are related to bathing activities of these, almost 2/3 happen during transfers ~ 50% of seniors have difficulty with bath transfers (either getting in/out or up/down) (Aminzadeh et al., 2001)
80% of seniors who have grab bars use them (Aminzadeh et al., 2001) A lab study noted that 99% of participants spontaneously used grab bars when available (Sveistrup et al., 2003) In the absence of proper grab bars, seniors use hazardous supports (Aminzadeh, Edwards, Lockett, 1999) WHY BATHROOM GRAB BARS?

WHY CANES? they have been linked to improved independence and/or reduced risk or perceived risk of falls seniors are often reluctant to use these or abandon use they are most likely to be independently sought by seniors, and are often selected and used incorrectly Aminzadeh & Edwards, 1997

WHY HIP PROTECTORS? 1993/94: 23,375 hip fractures reported in Canada - this number will increase to 88,124 annually by the year 2041 (CMAJ, 1998). Hip fractures are the 3 rd most common type of fracture following a fall – 19% of all fractures (Statistics Canada, 1999). Of all fractures, hip fractures cause the greatest number of deaths and lead to the most severe health problems and reduced quality of life (Wolinsky 1997; Hall 2000). 40% of hospital admissions following falls are related to hip fractures (HC, 2003). The average 1 year cost of a hip fracture is $27,527 - annually in Canada cost of $650 million (expected to rise to $2.4 billion by 2041) (Wiktorowicz et al., 2001).
WHY HIP PROTECTORS 12 months following a fracture: 20 to 24% of individuals older than age 50 will die within 12 months of suffering a hip fracture 24 to 40 % will require nursing home care 40% are still unable to walk independently 50% will require an assistive device like a cane or walker 60% will need help with one essential activity of daily living (e.g. bathing, dressing, food preparation) 80% are unable to perform at least one instrumental activity of daily living ( National Osteoporosis Association, 2003) 80% of participants in one study said they would rather be dead than experience the loss of independence and quality of life resulting from a bad hip fracture and the subsequent admission to a nursing home (Salkeld et al., 2000)
60-90% OF HIP FRACTURES ARE CAUSED BY FALLS (Lauritzen & Askegaard, 1992)
HOW HIP PROTECTORS CAN PREVENT HIP FRACTURES Shields placed against the unprotected hip Energy absorbing (soft pads) Energy shunting: Disperse impact across a wider area (typically hard shells*) (Lips & Ooms, 2000) * Some energy shunting materials are made of materials that are not hard plastic, e.g. HipShield is made of Trauma-Lite, the material used in motorcycle wear

DO ASSISTIVE DEVICES PREVENT FALLS? Canes: Review of literature concluded that “any links between AD use and falls in seniors are tenuous, at best” (Watzke, 2001) Research inconclusive because: people who use assistive devices are at higher risk of falling poor compliance with use of device most interventions have targeted multiple risk factors most studies descriptive in nature – unable to draw conclusions some video data studies, but in long-term care facilities poor controls in studies – studies needed that compare seniors using their mobility aid to those who should but are not using AD
Grab bars: Men with no grab bars were 3.7 times as likely to fall as men with grab bars (Sattin et al., 1998) DO ASSISTIVE DEVICES PREVENT FALLS?
Hip protectors: A review from the Cochrane group of elderly people in nursing homes, residential care, or supportive living at home concluded that “hip protectors appear to reduce the risk of hip fracture within a selected population at high risk of sustaining a hip fracture. The genereralization of the results is unknown beyond high-risk populations.” (Parker et al., 2003 ) NOTE: ENERGY SHUNTING + ABSORBING MOST EFFECTIVE
Assistive devices as innovations
The Diffusion of Innovation Relative advantage Extent to which an innovation is perceived as better than the idea it replaces Compatibility Consistency of intervention with existing norms, values, past experiences or needs Complexity Difficulty in understanding or using an innovation Trialability Option to experiment with an innovation before making a final choice about its use Observability Extent to which innovation results are visible to others
