Management of Sepsis in Elderly Patients

Initial Assessment and Stabilization

The American Geriatrics Society suggests that elderly patients presenting with fever, hypotension, tachycardia, and symptoms of cough, malaise, fever, nausea, and vomiting during influenza season strongly suggests sepsis, likely from influenza or secondary bacterial pneumonia 1
Immediate fluid resuscitation is critical for addressing hypotension in hemodynamically unstable patients, according to the American College of Cardiology 1
Vital sign monitoring should continue, with special attention to response to fluid resuscitation and oxygen saturation, as recommended by the American Heart Association 1
If hypotension persists after two fluid boluses, vasopressor therapy with norepinephrine should be initiated, which would require central line placement, as suggested by the American College of Cardiology 1

The American Geriatrics Society recommends placing the patient in droplet precautions immediately and performing influenza testing, especially during influenza season 2
Droplet precautions are essential to prevent transmission to other patients and healthcare workers, as stated by the Centers for Disease Control and Prevention 2

The American College of Cardiology recommends complete blood count, comprehensive metabolic panel, lactate, blood cultures, and chest radiography should be performed 1
Pulse oximetry should be performed, as oxygen saturation <90% is an important predictor of short-term mortality and respiratory failure, according to the Infectious Diseases Society of America 3

The American Geriatrics Society notes that elderly patients from long-term care facilities are at high risk for influenza complications and secondary bacterial pneumonia 2
The presentation of infection in elderly patients may be atypical, with fewer classic symptoms and more functional decline, as stated by the American Geriatrics Society 4
Fever in elderly patients is defined differently: a single oral temperature ≥100°F (37.8°C), repeated oral temperatures ≥99°F (37.2°C), or an increase in temperature of ≥2°F (≥1.1°C) over baseline, according to the Infectious Diseases Society of America 4

The patient's blood pressure of 85/40 mmHg indicates shock, which requires immediate intervention to prevent organ damage and death 5
Continuous oxygen therapy is indicated for patients with hypotension with systolic blood pressure < 100 mmHg 5
The British Infection Society and British Thoracic Society guidelines recommend that all patients with abnormal cardiorespiratory symptoms should have oxygenation assessed and those with hypotension should receive appropriate intervention 5

Empiric antibiotic therapy should cover community-acquired pneumonia pathogens, as secondary bacterial pneumonia is common in elderly patients with influenza 5

Option A (Place the patient in droplet precautions with influenza testing): While this is important, it does not address the immediate life-threatening hypotension which requires vasopressor support 5
Option B (Order metronidazole 500mg TID): Metronidazole targets anaerobic bacteria and is not appropriate first-line therapy for suspected influenza or community-acquired pneumonia 5
Option D (Order loperamide 2mg): Loperamide is contraindicated in patients with suspected infectious diarrhea and would not address the patient's primary issues of respiratory symptoms and hemodynamic instability 5

Monitor the patient closely for response to vasopressors and need for additional interventions such as mechanical ventilation if respiratory status deteriorates 5
