2. Overview • Epidemiology • Pathophysiology • Mechanisms of Injury • Assessment & Management Strategies • Conclusions “The more you complain, the longer God lets you live” Unknown

3. Geriatric Patients • EMT-B class = 150 hrs • EMT-P class = 1200 hrs • Geriatrics hours = 6 • 30-40% all EMS calls with a large percentage being ALS • Anatomically, sociologically & physiologically a “special” population “The secret of staying young is to live honestly, eat slowly, & lie about your age” ~ Lucille Ball

4. Defining “Geriatric” • Person >65 yo • Chronologic age = actual age • Physiologic age = functional capacity • US life expectancy 2010 • Male: 75.4 yrs • Female: 80.5 yrs • 15% US population • >85yo fastest growing population • By 2030, 25% population >65yo • Better living conditions, healthcare, medications & technology “You're only young once, but you can be immature forever” ~ John Greier

5. Geriatric Trauma Etiology • 7th leading cause of death in the elderly • 10-14% trauma patients >65yo • 25% trauma admissions • 28% accidental deaths • Enormous resource & financial burden • $20 billion annually • 33% trauma dollars • Trauma costs 3x greater compared younger persons • Injuries disproportionately severe • Mortality, morbidity, length of stay higher than younger patients with similar injuries • For each year >65, 10% increased chance of a trauma-related death “If I were younger, I'd know more” ~James Barrie

6. High Injury Risk • Normal aging & deterioration • Narrow physiologic tolerances • Decreased reaction time • Decreased eyesight & hearing • Postural instability • Fragile bones & vasculature “Old age is like everything else. To make a success of it, you've got to start young” ~Fred Astaire Trauma in Elderly - 6

7. Polypharmacy & Trauma • 80% on meds likely contributing to injury • Adverse events exponentially rise with number of drugs • 4% if 5 drugs • 10% if 6-10 drugs • 28% if 11-15 drugs • 54% if >16 • Common interactions • Anticoagulants & anti-platelets increase bleeding time • Anti-hypertensives & vasodilators limit vasoconstriction • Beta-blockers limit O2 demand response “It is not the years in your life, but the life in your years that counts” ~Adlai Stevenson

8. Impact of Co-Morbidities • Complication rate triples if one co-morbid illness • Oreskovich’s study on geriatric trauma outcomes: • 100 geriatric trauma pts • 96% independent pre-injury • 88% did NOT return to independence • 72% required NH placement “I am not young enough to know everything” ~Oscar Wilde

9. Geriatric Trauma Outcomes *p<0.001 “Grow old along with me! The best is yet to be” ~Robert Browning

10. Assessment Strategies • Speak slowly, directly & respectfully • Never “Sweetie”, “Honey”, “Pops” • Eye level in middle of visual field • Utilize family / care-givers but do not diminish patient’s contribution • Ask specific questions as patient may not volunteer information • Protect modesty & body temperature • Transport: • Medications • Glasses / hearing aids / dentures • All important paperwork (i.e. MOLST) “Like our shadows, our wishes lengthen as our sun declines” ~Edward Young

11. Assessment ~ Safety • If fall “mechanical”, consider pre-quels • Co-morbidities often causal • May not know / confabulate inciting event • Safety assessment may assist with MOI • Living conditions? • Stairs? • Medications & compliance? • Ambulation assists? • Fall hazards? • Driving safety? • Often reluctant to provide information • Loss of autonomy & independence • Separation from family • Hospitalization “The old believe everything, the middle-aged suspect everything, the young know everything“ O. Wilde

12. Assessment: Primary & Secondary Surveys • Primary Survey • Key: Vitals often unreliable! • A: Aggressive airway management Low intubation threshold Modified spinal immobilization • B: Supplemental O2 with chest / abdominal trauma • C: “Normal” BP may indicate hypotension / shock • Secondary Survey • Keys: Exam often underestimates injury Pain response, hypoxia, hypovolemia varies Pre-morbid illnesses complicate assessment "When you are older you will know that life is a long lesson in humility“ ~James Barrie

You grow old because you stop laughing” ~M Pritchard

22. Cardiovascular Pathophysiology • Decreased cardiac reserves • Limited increases in SV & CO • Decreased catecholamine response • Decreased valve efficiency • Hypovolemia = hypoperfusion • Lactic acidosis & shock without classic signs of shock • Decreased arterial compliance with increased arteriosclerosis • Baseline HTN, PVD • Conduction system degenerates • Arrhythmias “As the arteries grow hard, the heart grows soft” ~HL Mencken

Cardiovascular Pathophysiology • “Pre-quel” cardiac events • Limited ability to increase SV, HR & CO to combat hypovolemia • Increased O2 demand from cardiac stress not tolerated well • Ischemia • Worsening CO • Cardiovascular collapse • “Normal” BP if on antihypertensives = shock “To me, old age is always fifteen years older than I am” ~Bernard Baruch

24. Neurological Pathophysiology • Altered mentation increases with age due to atrophy, co-morbidities • Alterations impede assessments • Dementia / memory impairments • Vision, hearing, speech • Don’t mistake “deaf” with “dumb! • Difficult determining “normal” if no family, friends or caretakers “How old would you be if you didn't know what old was?” ~Satchel Paige

25. Neurology: Subdural Hematoma • SDH most common TBI • Often minor or “forgotten” trauma • Bridging veins tear causing blood to accumulate between dural & arachnoid spaces • Atrophy leaves large space for blood accumulation, delaying symptom onset • Mortality • Adult 4-8%; geriatric 15-30% • Mortality 90% if anticoagulated + GCS<8 • Dementia increases mortality risk “There are 3 signs of old age. The 1st is your loss of memory & the other 2….” Unknown

37. Management Strategies • Key: Prevention of early & late complications • Appropriate fluid resuscitation • Avoid low-flow states • Serial cardiopulmonary exams • Lung sounds • Cardiac monitoring • Pulse oximetry • Capnography • Multiple studies demonstrate under-triage of geriatric patients to trauma centers “Aging is not lost youth but a new stage of opportunity and strength” Betty Friedan

38. Geriatric Trauma Triage • Consider trauma center 1st line destination • If >80 yo, trauma center mortality 8% vs 56% in non-trauma centers • Recognize high risk injury patterns • Falls + AMS • Falls + inability to ambulate • Thoraco-abdominal • Pelvic or femur • Trauma + SBP <100 mmHg “Old age is the most unexpected of all the things that happen to a man” ~Trotsky

39. Airway Management • Early & aggressive • Limited cardio-pulmonary reserves • Limited ability to open mouth & move neck • Kyphosis & arthritis • Sedation can induce apnea • CPAP is great adjunct, but patients at higher risk for barotrauma / pneumothorax “You're getting old when all the names in your black book have MD after them” ~Arnold Palmer

40. >70yo triaged to trauma center for: GCS <15 + TBI Falls + evidence of TBI (even from standing position) SBP <100 mmHg Pedestrian struck Multisystem trauma Suspected proximal long bone fracture post-MVC Consider Trauma Center Triage if: COPD CAD / CVD Clotting disorder Warfarin therapy Diabetes Dialysis Immunocompromised Liver Disease Ohio Geriatric Trauma Triage (National Standard of Care) “I was taught to respect my elders; I’ve now reached the age when I don't have anybody to respect” ~ George Burns
