Objectives
1: Teach actionable risk factors for falls leading to
admission with emphasis on interventions
which can be initiated in the inpatient setting
2: Identify strengths and weaknesses of risk
stratification tools for the in-hospital fall
3: Critically appraise the quality of evidence for
interventions to reduce falls in the acute care
hospital
Clinical Case #1
Outpatient Fall Leading To Admission
Gertrude is an 88 y/o
woman admitted for back
pain after a fall stepping
off a curb outside her
assisted living
Xray demonstrates
thoracic compression
fracture.
Admit for pain control,
inability to ambulate.

IMPACT
30-40% of people over age 65 will have a fall each
year
In an elderly patient who has fallen, the risk of
having a second fall within a year rises to 60%
Rao SS. Prevention of Falls in Older Patients. AAFP 2005;72:81-88
Consequences
5-10% of community dwelling elderly who fall
will suffer a serious injury
– Up to 20-30% of elderly patients overall
Falls increase risk of going to nursing facility
– 3 fold increase for falls without injury
– 10 fold increase for falls with serious injury
8% of people > 70 come to ER for falls each year
– 1/3 will be admitted

Injuries
Fractures
1% of falls in the
elderly lead to hip fx
20-30% mortality in
the year after hip fx
¼ to ¾ of patients do
not recover prior level
of ADLs

Injuries
Other Fractures
– Humerus
– Rib
Subdural Hematoma
Prolonged lie- half of all elderly patients
who fall are unable to get back up
– 2o rhabdo, dehydration/ARF, pressure injury

A Brief Diversion
In Malcolm Gladwell’s book on cognition “Blink”, he
describes a fascinating psychology experiment.
A sample table is set up at two grocery stores for
customers to try a sample of jam.
On table has 6 varieties of jams, the other has 24
selections.
Which table do you think sold more jam?
Multiple Alternatives Bias
Table with only 6 varieties sold 10X more jam
The reason lies in the human psyche.
Faced by too many choices, customers freeze
up and make no decision at all.
A New Conceptual Framework
Fall risk has specific components:
Latent risk for fall
– Physiologic changes of aging
– Disease and medications
– Behavioral traits
Environmental trigger
– the “accident”
Underlying frailty
– Vulnerability to injury
EACH COMPONENT HAS CONCRETE ACTIONS TO
REDUCE RISK OF FUTURE INJURY
Postural
Challenges
Of Aging
OPPORTUNITY FOR INTERVENTION
↓Baroreceptor Sensitivity
↓Balance from vestibular and proprioception
↓vision (esp night)
↓reflex speed for correction
1) Physical Therapy
2) Ambulation/Gait assists
3) Sensory Aids
4) Remove Problematic Medications
5) Bed Alarms for dementia with impulsivity

What about Tests?
Orthostatic Vital Signs
Vitamin D levels
– Vitamin D deficiency associated with falls and osteoporosis
CBC, Chem7, Urinalysis are reasonable
– B12 levels and TSH if driven by other clinical cues
Brain imaging if neurologic findings on exam or if fall caused head injury
Echo is only indicated if exam suggests valvular disease
EKG/holter monitoring- low yield without syncope, chest pain, or palpitations
– Syncope is estimated to cause only 0.3% of falls

Rubenstein LZ et al. Falls and Their Prevention in the Elderly. Med Clin N Amer 2006;90:807-824
The Hard Part
Medications
Antidepressants
68% increased risk
There is usually a reason
patients were placed on a
medication
Neuroleptics/Antipsychotics
59% increased risk
Sedative/Hypnotics
47% increased risk
Antihypertensives
24% increased risk
NSAIDS
21% increased risk
Patients and physicians
may be resistant to
change
It is incumbent on us to
try to reduce problematic
medications when
adverse events are
occurring.

Geriatric Fall
Case #2
The In-hospital Fall
74 y/o previously independent man admitted for GIB
– Felt most consistent with hemorrhoids
– Admit for observation overnight
– Double occupancy room with another patient
There are Some Who Think the
Hospital is a Fancy Hotel
Fall Risk Stratification
Physician assessment as “Low” (binary) fall risk
“Moderate” risk per nursing assessment
The patients roommate is rated “High” risk
The Fall
Patient incontinent and attempting to reach
toilet using walker.
– Nursing aid assists patient to toilet
While on toilet roommate’s bed alarm sounds
– Imminent risk of falling out of bed
Nursing aid leaves bathroom to assist
roommate
– Bed alarm also summons nurse to room
The Fall
Returns to find patient has fallen in
bathroom
– Scalp laceration
– Humerus + Radius fracture
– Subdural hematoma
Outcome
Patient transferred to ICU
Fails swallow evaluation
Declines PEG tube
Aspirates in hospital
Death
Hospital Falls
2-12% of patients will have a fall in the hospital
Circumstances
20% with toileting
34% from bed
38% while ambulating
10-20% of in-hospital falls are recurrent events

The Challenge of the In-hospital Fall
Falls in the hospital are rarely witnessed
– Only 8% of hospital falls have staff present
Witnessed falls are still difficult to catch
Falls are widely underreported
– 44% of falls not reported as incident reports

Sari AB. Sensitivity of Routine System for Reporting Patient Safety Incidents in an NHS Hospital. BMJ 2007;334:79
Regulatory Environment
Injuries from hospital falls are “Never Events”
– --Medicare will no longer pay for them
Hospital falls with significant injury are
JCAHO reportable
– --sentinel events
Falls with injury in the hospital pose
malpractice risk
Risk Assessment- Physicians
How do physicians assess fall risk?
For the most part, physicians pay little or no
attention to this issue.
A simple physician falls screen:
– “Have you fallen in the last 6 months or are you afraid of
falling?”
– Get-Up-And-Go test
You learn a lot about strength, balance, and gait in 30 seconds.
Fernandez HM. House Staff Member Awareness of Older Inpatients’ Risk for Hazards of Hospitalization. Arch Intern Med 2008;168:390-396
Fall Risk Scoring Tools
Screening tools are available to target
interventions to high risk patients
STRATIFY Score
Downton Score
Morse Falls Scale
Hendrich II
Using the standards of EBM, even the best of
these tools has poor test performance
– Sens 67%
Spec 51%
– Predictive accuracy of 43.2% to 60%
ACTION on modifiable risk factors is far more
important than risk stratification

The literature provides little guidance
as to how the probability of injury
should be incorporated into hospital fall
policies as a modifier of the risk of a fall
itself.
Acute Post-Fall Evaluation
First priority is evaluation for injury
– Obvious and occult
Head to toe examination
– Palpation of spine, pelvis and ROM of extremities
– Fractures between occiput and C2 more likely in elderly
Immobilize neck pending CT scan if neck injury suspected
Head injury prompts CT scan
– Up to 10% of elderly pts with ICH lack focal deficits
– Scheduled neuro checks prudent

– 25% reduction in fall rates
2004 RCT in Community Hospital
– 21% reduction in falls
– No difference in fall related injuries

Effective…. According to Less
Rigorous Scientific Standards
Loch Ness Monster
Sasquatch
Of course by these standards….lots of
things are plausible
2006 Observational Trial of
Interdisciplinary Fall Prevention Program
No reduction in falls
No reduction in fall related injuries

Identified Problems
Incomplete predictive power of screening tools
Limited exposure time for intervention impact
– LOS in days vs. months to years
Incomplete adherence to fall reduction protocol
– Prior research demonstrates 43% non-adherence rates
– Our investigation found 64% non-adherence to bed alarms

RCTs to Reduce In-hospital Falls
8 Trials Since 1966
– Only two were exclusively acute care hospitals
1993 RCT of bed alarms
– Very small trial (35 patients in each arm)
– Non-significant reduction of falls
2006 Quasi-experimental multi-component trial
– Reduction in pts with recurrent falls
20% versus 56%
– No reduction in first falls
12.6% versus 11.8%

Findings of Systematic Review and
Meta-Analysis
No conclusive evidence that hospital fall
prevention programs can reduce the number of
falls or fallers
More studies are needed to evaluate trend
towards efficacy of actively targeting patient’s
most important risk factors
No evidence demonstrates acute care fall
prevention programs reduce injuries

Cochrane Review
In hospitals, multi-factoral interventions
reduced the rate of falls and risk of fallers.
– Results most robust for patients with longer
lengths of stay
