Should a 48-year-old female with a history of 2 cerebrovascular accidents (CVAs), congestive heart failure (CHF), diabetes mellitus (DM), and hypertension (HTN) be advised to visit the emergency room (ER) due to constant dizziness, nausea, vomiting brown material, and chills for 5 days?

Immediate Emergency Department Referral Strongly Recommended

This patient requires immediate emergency department evaluation and should not be managed via telemedicine. The combination of constant dizziness, persistent nausea with hematemesis (brown vomitus suggesting old blood), chills, and a 5-day duration in a patient with multiple stroke risk factors constitutes a potential hypertensive emergency with neurological symptoms requiring urgent assessment for acute target organ damage 1, 2.

Critical Risk Factors Mandating ER Evaluation

High-Risk Medical History

• Two prior strokes significantly elevate the risk of recurrent cerebrovascular events, making any new neurological symptom (including dizziness) a red flag requiring immediate imaging 3, 1
• Congestive heart failure increases the likelihood of acute decompensation presenting with dizziness, nausea, and systemic symptoms 3
• Diabetes mellitus and hypertension are established risk factors for both stroke and hypertensive emergencies, with diabetic patients at higher risk for target organ damage 3, 2

Concerning Symptom Pattern

• Constant dizziness for 5 days in a patient with prior strokes cannot be dismissed as benign peripheral vertigo—this duration and pattern increases the probability of posterior circulation stroke or hypertensive encephalopathy 3, 1
• Hematemesis (brown vomitus) suggests gastrointestinal bleeding, which combined with systemic symptoms could indicate multiple organ involvement or a hypertensive emergency affecting the GI tract 4, 5
• Chills may indicate infection, which in diabetic patients can precipitate diabetic ketoacidosis or hyperglycemic crisis requiring immediate intervention 6
• The combination of neurological symptoms (dizziness) with gastrointestinal complaints represents recognized manifestations of impaired cerebral autoregulation in severe hypertension 1

Why Telemedicine is Inadequate

Essential Immediate Assessments Required

• Blood pressure measurement to determine if this represents a hypertensive emergency (>180/120 mmHg with organ damage) requiring ICU admission and IV therapy 1, 2
• Neurological examination including mental status, gait assessment, coordination testing, and eye movement evaluation to detect cerebellar stroke—a common pitfall is missing truncal ataxia during bedside examination 3
• Fundoscopy to identify malignant hypertension with retinal hemorrhages, cotton wool spots, or papilledema 1, 2
• Laboratory evaluation including hemoglobin (for GI bleeding), platelets, creatinine, electrolytes, glucose, LDH, haptoglobin, and urinalysis to assess for thrombotic microangiopathy and acute kidney injury 1, 2
• ECG to evaluate for acute coronary syndrome or arrhythmias that could explain symptoms 1, 2
• Brain imaging (CT or MRI) to exclude acute stroke, intracranial hemorrhage, or posterior reversible encephalopathy syndrome (PRES)—MRI with FLAIR imaging is superior for detecting PRES 1, 6

Time-Sensitive Conditions That Cannot Be Excluded

• Cerebellar stroke can present with dizziness, nausea, and vomiting as the chief complaints, with peak swelling occurring several days after onset—deterioration depends on initial infarct volume 3
• Hypertensive encephalopathy presents with altered mental status, headache, nausea, and vomiting, and without treatment carries a 1-year mortality rate >79% 2, 6
• Acute decompensated heart failure in a patient with known CHF can manifest with dizziness and nausea, requiring immediate diuretic therapy and hemodynamic assessment 3
• Diabetic ketoacidosis or hyperglycemic crisis can be precipitated by infection or stress, presenting with nausea, vomiting, and altered mental status 6

Critical Pitfalls to Avoid

• Do not dismiss dizziness as "benign vertigo" in a patient with prior strokes and multiple vascular risk factors—unsteadiness represents a neurological symptom that significantly increases the likelihood of intracranial pathology 1, 7
• Do not rely on symptom duration to rule out serious pathology—cerebellar stroke can have delayed deterioration 4-10 days after onset when penumbral tissue progresses to infarction 3
• Do not overlook the significance of hematemesis in a patient with systemic symptoms—this could represent hypertensive gastropathy, stress ulceration, or a separate acute process requiring endoscopic evaluation 4, 5
• Age >65 years, ataxia symptoms, focal neurological symptoms, history of stroke, and diabetes mellitus are all independent predictors of central neurological causes of dizziness requiring urgent evaluation 7

Immediate Action Required

Instruct the patient or family to call 9-1-1 immediately rather than attempting to drive to the ER, as neurological deterioration could occur during transport 3. While awaiting emergency services, the patient should be positioned upright if experiencing respiratory distress, and continuous monitoring of vital signs should be maintained if possible 2.

The combination of this patient's high-risk profile, concerning symptom constellation, and 5-day duration without improvement represents a medical emergency that cannot be safely managed remotely and requires immediate in-person evaluation with access to advanced imaging, laboratory testing, and potential ICU-level care 1, 2.
