Geriatric Emergency Care

Introduction to Geriatric Emergency Care

Providing emergency care to older adults requires a distinct set of skills and knowledge. Age‑related physiological changes, atypical presentations of common diseases, and polypharmacy all influence assessment and treatment. This course synthesizes key concepts from a recent quiz, offering a comprehensive guide for clinicians, nurses, and medical students who care for geriatric patients in the emergency setting.

Recognizing Atypical Presentations

Myocardial Infarction Without Classic Chest Pain

Older patients often experience silent or atypical myocardial infarction (MI). The most indicative symptom is mild fatigue and confusion without chest pain. This subtle presentation can be mistaken for delirium or a simple infection, delaying life‑saving reperfusion therapy.

• Always assess cardiac biomarkers (troponin) when an elderly patient shows unexplained confusion or fatigue.
• Consider an electrocardiogram (ECG) even if classic chest pain is absent.
• Educate caregivers to report any sudden change in mental status as a potential cardiac event.

Infections Presenting as Delirium

Urinary tract infections (UTIs) are a leading cause of acute confusion in seniors. In the quiz, an 84‑year‑old with fever and catheter removal most likely had an acute urinary tract infection. The loss of a catheter can introduce bacteria, precipitating a rapid rise in temperature and altered mental status.

• Obtain a urine sample for culture when an older adult presents with new‑onset confusion and fever.
• Start empiric antibiotics promptly after collecting specimens.
• Implement catheter‑related infection prevention strategies: aseptic insertion, timely removal, and regular catheter care.

Systematic Assessment: The ABCDE Approach

The ABCDE framework (Airway, Breathing, Circulation, Disability, Exposure) remains the cornerstone of emergency assessment. For geriatric patients, the Disability component—checking consciousness level and pupil response—is crucial for detecting neurological emergencies such as stroke.

• Airway: Ensure patency; consider cervical spine protection if trauma is suspected.
• Breathing: Assess respiratory rate, effort, and oxygen saturation.
• Circulation: Monitor blood pressure, heart rate, and peripheral perfusion.
• Disability: Use the AVPU scale (Alert, Voice, Pain, Unresponsive) and check pupils.
• Exposure: Look for signs of trauma, rashes, or temperature abnormalities.

Stroke Identification: FAST and Beyond

Rapid stroke recognition saves brain tissue. The FAST mnemonic (Face, Arms, Speech, Time) guides quick screening. In the quiz, the S – Speech component evaluates speech disturbances, a hallmark of cortical involvement.

• Ask the patient to repeat a simple phrase (e.g., "The sky is blue").
• Listen for slurred or garbled speech, which may indicate an ischemic or hemorrhagic event.
• Document the exact time of symptom onset to determine eligibility for thrombolytic therapy.

Managing Polypharmacy and Medication Errors

Polypharmacy is common in older adults and increases the risk of adverse drug events. When a new medication leads to a sudden drop in blood pressure, applying the 6‑R rule (Right patient, Right drug, Right dose, Right route, Right time, Right documentation) is the best preventive strategy.

• Right patient: Verify identity using two identifiers.
• Right drug: Cross‑check the medication against the patient’s chart.
• Right dose: Adjust for renal/hepatic function.
• Right route: Ensure appropriate administration method.
• Right time: Consider timing relative to meals and other drugs.
• Right documentation: Record administration and monitor for side effects.

Respiratory Emergencies in the Elderly

Acute Hypoxemia and Altered Mental Status

A 90‑year‑old with rapid breathing, oxygen saturation of 86 %, and increasing somnolence requires immediate high‑flow oxygen and positioning to improve ventilation. Elevating the torso (semi‑recumbent) reduces diaphragmatic pressure and enhances lung expansion.

• Administer oxygen via a non‑rebreather mask or high‑flow nasal cannula.
• Re‑assess saturation after 5 minutes; aim for >94 % in most patients.
• Investigate underlying causes: pneumonia, COPD exacerbation, or pulmonary edema.

Dehydration‑Related Delirium

Dehydration is a frequent precipitant of delirium. The most potent risk factor is limited fluid intake combined with fever. Fever increases insensible water loss, while reduced intake prevents compensation.

• Encourage oral fluids (e.g., water, electrolyte solutions) unless contraindicated.
• Monitor input and output; consider intravenous fluids if oral intake is insufficient.
• Address fever promptly with antipyretics and treat the underlying infection.

Fall Management and Fracture Prevention

Falls are a leading cause of morbidity in older adults. During a fall incident, the nurse should avoid helping the patient sit up quickly, as rapid movement can exacerbate an undiagnosed fracture or spinal injury.

• First, assess the scene for safety and call for assistance.
• Stabilize the head and, if spinal injury is suspected, immobilize the spine before any movement.
• Document vital signs while the patient remains still to avoid further injury.
• Only after a thorough assessment should you consider gentle repositioning, preferably with a slide board or transfer device.

Key Take‑aways for Geriatric Emergency Care

• Atypical presentations are the norm, not the exception; always consider cardiac, infectious, and neurologic causes when mental status changes.
• Use the ABCDE and FAST algorithms as structured guides, but adapt them to the older patient’s baseline functional status.
• Implement the 6‑R rule to minimize medication errors, especially in polypharmacy contexts.
• Prioritize early oxygen therapy and proper positioning for respiratory compromise.
• Prevent dehydration‑related delirium by ensuring adequate fluid intake and managing fever promptly.
• When managing falls, avoid rapid repositioning; prioritize spinal precautions and thorough assessment.
