WHAT IS A FALL?
DEFINTION OF A FALL?
“An involuntary event producing a change in
posture resulting in an unplanned change in
position.”
Most falls are multifactorial in origin, resulting
from interaction between the impaired stability
of an individual and the hazards and demands
of the environment.
FALLS DEFINED
ACCORDING TO THE MERCK MANUEL OF
GERIATRICS :
A FALL IS ANY DROP FROM A HIGHER
TO A LOWER POSITION
Outline
 Frightening statistics
 An organized approach
 Intrinsic versus Extrinsic factors
 Physiological versus Pathological
 Preventative strategies
 Specific gait disturbances related to falls
FALLS !!!
 1 in 3 people over age 65 fall each year
 Falls incidence per Cochrane review 2009
 111 trials (55,303 participants)
 30% of older adults fall each year
 Increased to over 40% of elderly over 80
Keeping the hospitals
busy
10% of falls result in injury
5% result in fractures
5th leading cause of death in elderly
Bad prognostic indicator
65% of LTC residents with >6 falls were dead
within 2 years
 5.3% of admissions related to falls.
 8% of >70 will visit ER post fall during year.

Let us learn from others
Every 18 seconds an
older adult is treated
in an emergency
department for a fall,
and every 35 minutes
someone in this
population dies as a
result of their injuries.

Message for you
 Falls rarely associated with single factor
 Intervention often reduces risk factors
without eliminating risk
 “Any condition which decreases ‘well
being’, will increase sway, reduce
stability, decrease judgement &
compensatory mechanisms and will
increase risk of falls”
When do falls occur?
Statistics show that most falls occur in
the daytime when people are more
active, around 11 am and between 4 pm
and 6 pm.
Where do people fall?
 50% of falls take place in and around the
home.
 25% of falls take place in public places
 21% occur in residential care environments.

 Intrinsic physiological factors:

– dark adaptation
– cataracts?
– glare

– decreased sensory input

How does psychiatry
interact with falls?
Psychiatric factors
 Dementia & cognitive impairment
 Depression
 “Fear of Falls” & Anxiety
Medicines from one family
This is geriatrics- always

Extrinsic Factors
Risk Factor for Falls
Visiting “the old folks at
home”
Extrinsic factors:
 Majority of environmental falls happen
during normal activities
 Stairs are #1
 other common spots:
• Bedroom transfers
• Kitchen cupboards
• Bath and toilet transfers

Applying the guidelines to the
individual
Treat any acute illness that precipitated the fall
Treat specific conditions affecting balance
Correct postural hypotension or arrhythmia
Rationalise medication especially psychotropic
agents
Correct visual impairment where possible
Physiotherapy: balance and strength training
OT: environmental hazard check, safety
awareness
Occupational Therapy
considers the physical context
 During Assessment
 Understand obstacles/barriers
 Consider individual, groups, populations who use the
physical space
 During intervention
 Reduce activity demands from the environment
 Insure adequate supports
 Facilitate performance though the use of the
environment
 Avoid further functional decline and excess disability
caused by environmental factors
How to stand up safely
 Sit on the edge of the bed/chair with feet
on the floor for a few minutes before
getting up.
 Stand slowly using both arms to push up
for support.
 Make sure you have good balance and do
not move off if you feel lightheaded or
dizzy.
 Use support when bending down and stand
back up slowly.

 An added benefit for preventing falls.
 Prevent fractures
Home Strategies
Hip protectors
Cochrane review 2006
 Meta-analysis of 11 trials in care home settings:
Reduction in incidence of hip fracture (RR 0.77 (95% C.I. 0.62-0.97)
(but weak cluster randomisation methodology in 7 trials)
 Meta-analysis of 3 individually randomised trials in community
settings: No reduction (RR 1.16 (95% C.I. 0.85-1.59)
 Poor acceptance (median 68%) and compliance rates (median 56%)
 Conclusion: hip protectors are ineffective for those living at home and
their effectiveness in an institutional setting is uncertain.
