Title: Hospital Falls and Falls that Lead to Hospitalization The Inpatient Perspective


1
Hospital Falls and Falls that Lead to
HospitalizationThe Inpatient Perspective
Ethan Cumbler MD, FACP Associate Professor of
Medicine Director UCH Acute Care For Elderly
Service University of Colorado Denver 2010
2
Disclosures
  • None

3
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

4
Clinical 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.

5
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

6
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 gt 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 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?

12
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.

13
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

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

The 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.

Case 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

22
Fall Risk Stratification
  • Physician assessment as Low (binary) fall risk
  • Moderate risk per nursing assessment
  • The patients roommate is rated High risk

23
The 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

24
The Fall
  • Returns to find patient has fallen in bathroom
  • Scalp laceration
  • Humerus Radius fracture
  • Subdural hematoma

25
Outcome
  • Patient transferred to ICU
  • Fails swallow evaluation
  • Declines PEG tube
  • Aspirates in hospital
  • Death

26
Hospital 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

Consequences
  • 30 with minor injury
  • 4 with major injury
  • Lacerations/bleeding
  • Hematomas
  • Fractures/dislocation
  • Traumatic brain injury
  • ?? hospital charges
  • ? LOS
  • Litigation
  • Serious injuries
  • Failure to follow procedures to prevent recurrent
    falls
  • Delays in injury recognition

Half of all patients with hip fracture from
in-hospital fall will be dead within the
year -Twice the rate seen in the community Risk
of injury from in-hospital fall rises by 19 for
each decade of age

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

hospitalized patients evaluated for falls. JHM

System for Reporting Patient Safety Incidents in
an NHS Hospital. BMJ 200733479
29
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

30
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.

Older Inpatients Risk for Hazards of
Hospitalization. Arch Intern Med 2008168390-396
31
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.
33
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

Observational Trials of Hospital Fall Reduction
Protocols
  • 2004 Observational trial
  • 25 reduction in fall rates
  • 2004 RCT in Community Hospital
  • 21 reduction in falls
  • No difference in fall related injuries

41
2006 Observational Trial of Interdisciplinary
Fall Prevention Program
  • No reduction in falls
  • No reduction in fall related injuries

42
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 patients 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
