Emergency And Acute Medicine - Geriatric Trauma
Overview And Scope
Geriatric trauma addresses the unique challenges involved in the evaluation and management of injured older adults. Management should follow standard trauma principles while incorporating age-related physiologic changes, comorbid illnesses, and medication effects. Advanced age, commonly defined as over 65 years, is an independent risk factor for poor outcomes after trauma. Chronologic age does not always reflect physiologic reserve, requiring individualized assessment.
Epidemiology And Risk Profile
Trauma-related morbidity and mortality rise significantly with increasing age. Older adults experience higher complication rates, longer hospitalizations, and increased mortality compared with younger patients sustaining similar injuries. Even low-energy mechanisms can result in severe injury because of diminished physiologic reserve.
Common Mechanisms Of Injury
Falls are the leading cause of injury in patients older than 65 years and frequently occur from standing height or flat surfaces. Motor vehicle collisions are the second most common cause and the leading fatal mechanism. Pedestrian–vehicle collisions occur more often due to impaired vision, hearing, gait, and cognition. Burns carry higher fatality rates compared with younger adults for similar burn size. Violence is less common but should raise concern for elder abuse, which is often underrecognized. Elderly patients are particularly vulnerable to serious injury from low-energy trauma.
Triage And Initial Assessment
Thresholds for trauma activation and transfer to major trauma centers should be lower in elderly patients. Any injured older adult with potential need for surgical, neurosurgical, or orthopedic intervention should be considered for trauma center care.
Clinical Evaluation And Survey Approach
Assessment follows the same primary and secondary survey structure used for all trauma patients, but normal vital signs may be misleading. Hypoperfusion is often masked by blunted physiologic responses, chronic disease, and medication effects.
Airway And Cervical Spine Considerations
Airway management may be more difficult due to dentures, cervical arthritis, temporomandibular joint disease, and limited neck mobility. Early intubation should be strongly considered, as delayed airway control is a common and dangerous error.
Breathing And Ventilation Assessment
Age-related changes in chest wall compliance and weakened respiratory muscles reduce ventilatory reserve. Blunted responses to hypoxia and hypercapnia delay clinical deterioration. A lower threshold for intubation is recommended, and adequate analgesia for chest wall pain is essential to maintain ventilation.
Circulatory And Hemodynamic Evaluation
Heart rate and blood pressure may not accurately reflect cardiac output or shock severity. Chronotropic response to hypovolemia is often impaired, and medications such as beta-blockers and calcium channel blockers blunt tachycardia. Baseline hypertension may conceal relative hypotension. Antiplatelet and anticoagulant therapy increases bleeding risk.
Neurologic Status And Disability Assessment
Rapid neurologic evaluation is critical. Cerebral atrophy may delay the presentation of intracranial hemorrhage, and mental status changes should never be attributed solely to dementia or baseline cognitive impairment. Anticoagulated patients are at increased risk for delayed intracranial bleeding.
Exposure And Secondary Survey
Complete exposure is necessary to identify injuries, while actively preventing hypothermia. After stabilization, a thorough head-to-toe examination and complete secondary survey should be performed.
History And Comorbid Conditions
Elderly trauma patients must be evaluated as both trauma and medical patients. Comorbidities, medications, and allergies are central to management. Medical events such as syncope, hypoglycemia, arrhythmia, stroke, or infection may precipitate trauma. Details of the mechanism and prehospital care should be obtained from emergency medical services whenever possible.
Diagnostic Testing And Imaging Strategy
Baseline studies include CBC, arterial blood gas, electrolytes, renal function, glucose, coagulation profile, lactate, base deficit, and blood typing. Cervical spine and chest imaging are mandatory in major trauma. Liberal use of head CT is recommended for elderly patients with head injury. CT imaging is often preferred over plain radiographs due to degenerative changes. Abdominal trauma evaluation depends on hemodynamic stability, with CT using IV contrast for stable patients and FAST or diagnostic peritoneal lavage for unstable patients. Renal function should be assessed prior to contrast administration.
Prehospital Management Priorities
Key priorities include airway control, hemorrhage management, immobilization, shock treatment, and rapid transport to an appropriate trauma facility.
Initial Resuscitation And Stabilization
Airway management must account for anatomic challenges. Supplemental oxygen, continuous pulse oximetry, capnography, and serial blood gases help monitor respiratory reserve. Circulatory resuscitation should use cautious crystalloid boluses of 250–500 mL with early consideration of red blood cell transfusion. Over-resuscitation can precipitate heart failure. Serial lactate and base deficit measurements guide shock management. Renal perfusion must be protected due to reduced creatinine clearance.
Injury Patterns Common In The Elderly
Head injuries more commonly result in subdural rather than epidural hematomas. Cervical spine injuries, particularly C1–C2 and odontoid fractures, often occur after minor trauma. Vertebral compression fractures are frequent. Rib fractures significantly increase pneumonia risk and mortality with each additional fracture. Abdominal injury patterns are similar to younger adults but require high clinical suspicion. Pelvic and hip fractures are common due to osteoporosis and require early definitive management to restore mobility.
Emergency Department Management Principles
Early cardiopulmonary monitoring, prompt stabilization, and rapid surgical consultation are essential. Definitive management is often surgical. Elderly patients benefit from aggressive yet carefully balanced trauma care, ideally within trauma centers. Advance directives and goals of care should be identified as early as possible.
Disposition And Admission Decisions
Most elderly patients with significant trauma should be admitted for observation or intensive monitoring. A lower threshold for ICU admission is appropriate for polytrauma, chest wall injuries, abnormal vital signs, or evidence of hypoperfusion. Patients with minor trauma and negative evaluations may be observed and discharged if stable.
Follow-Up And Referral Planning
Follow-up and specialty referral depend on the injuries sustained and must be clearly arranged prior to discharge.
Clinical Insights And Common Errors
Seemingly minor mechanisms can cause serious injury due to limited physiologic reserve. Medications such as beta-blockers and anticoagulants complicate assessment and management. Normal blood pressure and heart rate do not exclude shock. Geriatric trauma patients must always be managed as both trauma and medical patients.
