2Disclosures
3Objectives
- 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
4Clinical Case 1Outpatient Fall Leading To
Admission
- PMH
- Mild Alzheimer's Dementia
- HTN
- Urge incontinence
- Depression
- Insomnia
- Medications
- Clonidine 0.1 mg bid
- Aspirin 81 mg daily
- Sertraline 50 mg daily
- Amitryptiline 50mg at night
- 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.
5IMPACT
- 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 20057281-88
6Consequences
- 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 gt 70 come to ER for falls each year
- 1/3 will be admitted

7Injuries
- 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

8Injuries
- 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

11A Brief Diversion
- In Malcolm Gladwells 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?
12Multiple 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.
13A 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

15What 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

16The Hard PartMedications
- Antidepressants
- 68 increased risk
- Neuroleptics/Antipsychotics
- 59 increased risk
- Sedative/Hypnotics
- 47 increased risk
- Antihypertensives
- 24 increased risk
- NSAIDS
- 21 increased risk
- There is usually a reason patients were placed on
a medication - Patients and physicians may be resistant to
change - It is incumbent on us to try to reduce
problematic medications when adverse events are
occurring.

19Case 2The 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

Hotel

22Fall Risk Stratification
- Physician assessment as Low (binary) fall risk
- Moderate risk per nursing assessment
- The patients roommate is rated High risk
23The Fall
- Patient incontinent and attempting to reach
toilet using walker. - Nursing aid assists patient to toilet
- While on toilet roommates bed alarm sounds
- Imminent risk of falling out of bed
- Nursing aid leaves bathroom to assist roommate
- Bed alarm also summons nurse to room
24The Fall
- Returns to find patient has fallen in bathroom
- Scalp laceration
- Humerus Radius fracture
- Subdural hematoma
25Outcome
- Patient transferred to ICU
- Fails swallow evaluation
- Declines PEG tube
- Aspirates in hospital
- Death
26Hospital Falls2-12 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

28The 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

hospitalized patients evaluated for falls. JHM

System for Reporting Patient Safety Incidents in

29Regulatory 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
30Risk 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.

31Fall 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

32The 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.
33Acute 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

42Identified 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

44Findings 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 patients most
important risk factors - No evidence demonstrates acute care fall
prevention programs reduce injuries
