Leading change. Improving care for older adults.
LEARNING OBJECTIVES
• Describe the unique presentations of geriatric
trauma
• Identify areas of particular risk for elderly
patients with traumatic injuries
• Suggest care process changes that may
improve the care of geriatric trauma patients
Slide 2
GERIATRIC TRAUMA: OUTLINE
• The basics
• Rib fractures
• Pelvic fractures
• Head trauma
• Warfarin
• C-spine fractures
• Triage
Slide 3
GERIATRIC TRAUMA: DISCLAIMERS
• Most studies are retrospective reviews
• No standard definition of “geriatric” or
“elderly”
Slide 4
GERIATRIC TRAUMA: EPIDEMIOLOGY
• Elderly are growing in numbers
• Patients ≥65 years account for 10% of all
traumas, but 28% of deaths!
• Trauma is the 7th leading cause of death in
elderly
Slide 5
GERIATRIC TRAUMA: MECHANISMS
• Falls — most common
 Balance, strength, vision
• Motor vehicle collision (MVC) — most fatal
 Judgment, vision, reaction times decreased
 Crash fatality rates are much higher
• Burns — 1/5 of all burn unit admissions
 Mortality estimate = age + % burn
Slide 6
GERIATRIC TRAUMA:
COMPLICATING FACTORS
• Past medical history
 Cardiac and pulmonary disease limit physiological response
to stressors
 Vital signs are difficult to interpret
• Medications
 Anticoagulants
 Beta blockers
• Cause of the event
 Myocardial infarction, syncope, stroke, hypoglycemia

Slide 17
RIB FRACTURES
IN THE ELDERLY (1 of 2)
• Prospective cohort of 405 patients admitted with rib
fractures from blunt trauma
• 113 patients > 65 years old
• Elderly had much higher mortality (20% vs. 9%)
• Isolated thoracic trauma
 75% of elderly patients sustained this by fall from standing
 Mortality 15% if age >65; 0% if <65
 Pneumonia 34% if age >65; 11% if <65
• Most geriatric deaths occurred >72 hours after trauma
and resulted from sepsis or respiratory failure
Bergeron E, et al. J Trauma. 2003;54:478-485.
Slide 18
RIB FRACTURES
IN THE ELDERLY (2 of 2)
Age (years)
3-6 rib fractures
>6 rib fractures
<65
≅10%
≅25%
≥65
≅30%
>60%
If >65 with 3 or more rib fractures, admit;
if >6 rib fractures, ICU
Bergeron. J of Trauma 2003; 54: 478-85.
PELVIC FRACTURES
IN THE ELDERLY (1 of 2)
• Usually associated with falls from standing &
MVCs
• Higher percentage of lateral compression
fractures than in younger patients
 Fewer “severe” fracture patterns
• High rates of hemorrhage, transfusion, and
ICU admission, even with “benign” fracture
patterns
Slide 20
PELVIC FRACTURES
IN THE ELDERLY (2 of 2)
• 92 consecutive blunt trauma pelvic fracture patients received
angiographic embolization (AE) for “liberal indications”:
 Hemodynamically labile, concerning fracture pattern (open
book, vertical shear, butterfly), or pelvic hematoma on CT
• Patients >60 years (n=17) were compared with younger patients
 No difference in injury severity score, pelvic fracture pattern,
SBP, or blood requirement
 >60 years: 94% chance of active bleed vs. 52% in younger
patients
• Consider AE before hemodynamic collapse in elderly patients
with significant pelvic fractures
Kimbrell. Arch Surg. 2004.
Slide 21
CASE 2
• 90-year-old woman presents 3 days after fall
in bathroom, when she hit her head on toilet
• No symptoms for 2 days
• This morning, mild headache and face pain
• Medications: warfarin, oxycodone,
amitriptyline
Slide 22
HEAD TRAUMA IN ELDERLY
• Bridging veins travel further
• More space for hematoma collection
before symptoms
• Age >65 have 30%85% mortality
with intracranial hemorrhage (ICH)
 25 higher than younger
patients with matched injuries
• Considered high-risk in brain imaging
protocols (New Orleans, Canadian)
Webmm.ahrq.gov, retrieved June 3, 2011.
Slide 23
WARFARIN AND ICH IN ELDERLY
• 9% of elderly patients with traumatic brain injury are
on warfarin
• Risk of spontaneous ICH on warfarin is 0.35.4%
• Blunt head trauma on warfarin with minimal or no
symptoms, 7%14% have ICH
• Patients frequently have supra-therapeutic INR
 11% have INR >5
• Beware delayed acute subdural hematoma (DASH) —
consider admission for observation even if head CT is
negative
• Check INR
Slide 24
AGGRESSIVE
COUMADIN PROTOCOL (1 of 2)
• Emergency department initiated new protocol for
patients with suspected head trauma on warfarin
 Immediate evaluation
 Immediate head CT
 Type & cross match
 Thaw 2 units AB FFP
• If positive head CT
 Transfuse FFP, Vitamin K IV, neurosurgery evaluation
• If negative head CT
 Admit for observation
Ivascu FA, et al. J Trauma. 2005;59:1131-1139.
Slide 25
AGGRESSIVE
COUMADIN PROTOCOL (2 of 2)
• 82 patients, 19 with ICH
• Time to initiate warfarin reversal dropped from
4.3 hours pre-protocol to 1.9 hours
• Mortality dropped from 48% to 10%
Ivascu FA, et al. J Trauma. 2005;59:1131-1139.
Slide 26
CASE 3
• A 97-year-old woman fell while getting out of
bed
• Normal activity throughout day; eventually
presents with moderate neck pain
• No neurological deficits on exam
Slide 27
GERIATRIC C-SPINE FRACTURES
Type II odontoid fractures are the most common
LearningRadiology.com, retrieved June 3, 2011.
Slide 28
ODONTOID FRACTURES
Insert image/ diagram of 3 types of odontoid
fractures.
GERIATRIC C-SPINE FRACTURES
• Blunt trauma victims >65 years are 2 more likely than
younger patients to have C-spine fractures
• Odontoid fractures: 20% of elderly C-spine fractures
vs. 5% in younger patients
• Debate in literature about management of types II, III
odontoid fractures
• Patients >65 years included in NEXUS, identified as
high risk in Canadian C-Spine Rule
• X-rays frequently inadequate
• Have a low threshold to use CT on geriatric C-spine
Touger. Ann Emerg Med. 2002.
Slide 30
TRIAGE
• Elderly trauma patients are under-triaged, in
violation of paramedic protocols
• Should the elderly be triaged more
aggressively?
Slide 31
CRITERIA FOR TRAUMA
TEAM ACTIVATION (TTA) (1 of 3)
• Review of Trauma
Registry at UCLA and LA
County from 19932000
• Included admitted trauma
patients age >70, except
interhospital transfers,
ground-level falls,
subacute subdurals
• 25% met TTA criteria:




SBP <90 or Pulse >120

Demetriades D, et al. J Trauma. 2001;51:754-756.
Slide 33
CRITERIA FOR TRAUMA
TEAM ACTIVATION (TTA) (3 of 3)
• The same UCLA group added age 70 years as a TTA
criterion
• Data were analyzed on 336 trauma patients with ISS > 15
and age 70 years: 260 patients admitted before age
became a criterion and 76 admitted afterward
• Groups were similar in injury, age, gender, ISS, and
Abbreviated Injury Score
• Mortality was 53.8% before, 34.2% after (P=.003)
• Consider early and aggressive resource mobilization for
elderly trauma victims
Demetriades D, et al. Br J Surg. 2002;9:1319-1322.
Slide 34
GERIATRIC TRAUMA:
TAKE-HOME POINTS
• Elderly patients break easily — don’t minimize
• Mobilize resources for elderly trauma victims
• Rib fractures associated with high mortality; if patient
has >2 rib fractures, admit
• Consider angiographic embolization for pelvic
fractures even before hypotension
• Beware warfarin!
• Low threshold for CT of geriatric C-spine; when
(re)taking the boards, think odontoid
Slide 35
CASE 1
• EMS brings in a 71-year-old woman who was “Tboned” on the passenger side while driving at an
unknown rate of speed.
• There was no air bag deployment, but it took several
minutes to get her out of her car and she was nonambulatory at the scene.
• Upon examining her, you note that she has chest wall
bruising, a tender pelvis, and vital signs significant for
BP of 100/60, HR of 80, and oxygen saturation of
100% on a non re-breather oxygen mask.
Slide 36

B. Burn mortality is estimated at percentage body surface burned plus
age of patient in years.
C. Falls are a common cause of significant morbidity in the elderly.
D. Motor vehicle accidents are the most common cause of traumatic
injuries in the elderly.
Slide 37
CASE 1, QUESTION 2

Which of the following statements regarding triaging
elderly trauma patients is not true?
A. Cardiac and pulmonary disease limit physiologic response to
stressors.
B. Elderly patients involved in traumatic accidents are more likely
to be triaged to trauma centers than younger patients with the
same pre-hospital assessment by EMS providers.
C. Institutions that include age as a criterion in their trauma
activation system have improved outcomes in caring for geriatric
trauma patients.
D. Medications taken by the elderly can render vital signs more
difficult to interpret.
Slide 39

department complaining of a headache and painful
neck.
