Background

Geriatric Trauma

2 Common Presentations

ALOC

Infections

Elderly Abuse

No syncope. No weakness

Feel free to share … Q/A …fun and engaging
Background

Elderly 15-20% of ED visits and increasing


Have longer ED length of stay and consume more resources
More likely to arrive via ambulance and be admitted [40% ED admissions]

More likely to have medical rather than surgical admit

Atypical presentations are the norm [esp >85yo “oldest old”]

Most common causes:







Cardiac  Ischemic HD, dysrhythmia &CHF
Syncope
CVA
Pneumonia
Abdominal disorders
Dehydration
UTI
Adverse Outcomes

Elderly pts that are sent home have signif risk of AO’s

Risk factors for adverse outcomes:






Decline in Baseline function
Recent admit
Lives alone
No social Support
Polypharmacy [> 3 meds]
Certain diseases [CV, DM, dementia, depression]

Mortality 10%  3 mo after ED visit

25% ED bounce-back and 25% post-D/C admit rate

Incumbent on EP’s to identify and manage this risk
List meds assoc with
Adverse outcomes

12%  30% elders admitted in whole/part due to drug reactions
or interactions.

Altered pharmacokinetics & pharmacodynamics

Worst offenders:

cardiovascular meds  diuretics  NSAID 
hypoglycemics  anticoagulants.

Speaks to the fact that we shouldn’t be fiddling if we can help it.
CASE

70 yo trying to put up Christmas lights.

Fall off roof.

EMS  can we go to PLC?

List 3 physiologic considerations in caring for the elderly trauma
patient and how they change you management.
Physiology

Generally more severe response to any given mechanism

Airway:



Breathing:


Reduced FRC, compliance and chest wall expansion  Desat QUICK
Circulation:




Edentulous  can’t bag.
Reduced oral diameter and neck extension.
Limited capability to increase CO
Might not vasoconstrict Due to cardiac meds
Result is that these pts cannot tolerate shock
Disability & Exposure:



Dura attached to inner table  less EDH but MORE SDH
Spinal stenosis
Osteoporotic  trivial trauma  fracture
Other physiology
Other physiology
Other physiology
Geriatric Trauma

Injury significant cause of death due to:


Physiologic differences
Injury patterns

> 80 + trauma = 4 fold mortality cf younger trauma pts

Falls [40%]  MVC [auto vs ped]  other [assault]

Gimme 3 risk factors for falls:

RF’s:




Meds [narcotics, cardiac meds]
Hx CVA
Cognition
Visual and hearing impairment
Falls and MVC’s

Falls:





MVC’s:



¼ due to underlying medical condition
Most common injury is #’s [ occurring in 5%]
Even with minor mechanism, absence of clinical findings does not
rule out injury.
Low threshold for radiography
NB Single-vehicle Accidents  need to r/o medical cause
Mortality as high as 20%
Am Coll Surg recommendations anyone > 55 goes to trauma
centre.
Back to Case

70 yo Male in collar on spine board.

VS: 80, 110/45, 30, 90%, 370, c/s 5.0, GCS E3, V4, M6

AMPLE  on BB/warf for AF. HCTZ for HTN & has RA

C/o numb fingers, L chest wall pain.

O/e: Tender L CW, Abdo non-specific tender but soft. Cannot do
pelvis because RT is doing a “fem-poke”

Doctor?
Head injuries

Much higher mortality  1/5 SDH do not survive

75% admit rate

Indications for warfarin reversal?

What if he tripped, fell, small abrasion forehead. GCS 15. No
deficits? Management?

Minimal mechanism + coumadin + Normal exam = 7- 15% serious
intracranial hemorrhage.

ULTRA LOW THRESHOLD FOR CT
Acute/chronic Subdural
Spinal Injuries

Most common mech is a fall

Degen joint dis  reduced mobility  brittle spinal column

Most common level of injury is C1-C3

Most common injury is Type 2 Odontoid

Overall mortality 15%
Central Cord Syndrome

Two places where spinal cord is large relative to canal:


C5-T1 [brachial plexus] & L2-S3 [lumbosacral plexus].
Limited space + Hyperextension injury  cord gets pinched by
inward bulging of ligamentum flavum  central contusion
Clinically:

Bilateral motor weakness of upper extremities >> lower extremities

distal muscle groups >> proximal muscle groups.

Can have burning dysesthesias in upper extremities.

Variable prognosis  goes by age

> 50yo  only 30% regain bladder function & 50% regain ambulation.
Central Cord
Chest Injuries

Falls >> MVC cause broken ribs

Increased incidence of solid organ injury

CANNOT tolerate


huge risk of respiratory failure and Pneumonia
BOTTOM LINE : Elderly + rib fractures  Low threshold for
admit.
Abdominal Injuries

Seen in 30% older trauma patients.

Mortality = 25%

Even with careful selection, Non-operative management only
75% success.

Unreliable exam = Liberal use of CT
Pelvic Injuries

Falls  break pelvis  also bleed more

Rami >> acetab >> ischium

Aggressive management:

Binder

Warm Fluids

Blood

Consider embolisation

GLF + no # on xray + cannot walk?

Needs MRI
myweb.lsbu.ac.uk
Extremity Injuries

Low mechanism + osteoporosis = Fracture!

Perform really good tertiary survey EVEN FOR MEDICAL
PATIENTS


Case of syncope on park bench  when went to check for pedal
edema  ouch!  had # ankle on Xray!
Low threshold for radiography
Trauma Summary

Go into “elder mode”

Liberal use of radiography

Think of elder-specific issues [central cord]

Elder Airway  Edentulous, reduced mouth open/neck mobility

Elder Breathing  rib fractures = signif morbidity

Elder Circulation  meds will hide shock. PELVIS!
Mental break

Ddx?
ALOC in the Elderly

Prevalent in the ED.

Associated with adverse outcomes

Poorly recognised and even more poorly documented

EP’s assume that dementia is being managed NOT

Still high rate of mis-diagnosis of delirium

Mortality 20%
ALOC in the Elderly
Evaluation

Difficult

Average elderly pt has 3 medical conditions. NH patient = 10

Will end up using more tests

Despite this need to bite the bullet and be meticulous and
thorough


H/x should be exhaustive [a la Pediatric hx]

P/e should be more meticulous.
NB they have benign presentations despite catastrophic path.

Eldery Infections

Higher risk due to physiologic changes

Higher morbidity and mortality cf younger pts

Can be difficult to sort out due to:

Vague presentation  ALOC & weakness

Atypical features and low sensitivity of serum markers

Co-morbidities
Elderly Fever/bacteremia

10% of ED visits

When present almost always bacterial

Absence of fever not reassuring.


Afebrile bacteremia in 20%

NH patients in particular do not seem to mount a febrile response.
Should prompt a thorough search


CBC, BC, Urine Culture and CXR
¾ will end up being admitted
Elderly fever/Bacteremia

Most common complaints  ALOC, Weakness, confusion and
decreased functional status

> 85yo more likely to present atypically

Urine >> resp >> unkown >> abdo

Questions:

Should the patient be admitted?

What is the treatment for elderly CAP?

What about NHAP?
Elderly Pneumonia

Leading cause of death. Particularly prevalent in >85.

Atypical presentations esp in NH patients [ALOC more likely]

CAP mortality is 10% overall

NHAP  much higher mortality
Pneumonia
Pneumonia risk stratification

Risk Stratification by “Pneumonia Severity Index”

Validated score based on 14 clinical and 7 lab variables

Group 1 [score <51] = Low risk  mort only 0.5%  outpatient rx

Group II [51-70 mort 0.9%]  Same  outpatient rx

Group III [71-90 mort 1.2%]  intermediate risk


consider for outpt rx if they’re only in group on the basis of age, one
comorbidity or one abn finding.
To be safe  short admit for group III

Group IV [>91 points] 9% mort  admit

Group V [>130 points] 27% mort  admit
Pneumonia Severity Index
Community Acquired

CAP:
1.
S pneumo  50%
2.
H.Flu & Moraxella
3.
Atypicals [mycoplasma ,chlamydia , legionella]  15%
•
Post influenza = S aureus
Management:


Outpatient no co-morbidities?  usual meds [Zpack etc]

Comorbidities?  resp fluoroquinolone [GATi, GEMI, LEVO, MOX]
