Difficulty: MediumPulmonary and Critical Care

A 62-year-old woman comes to the urgent care clinic complaining of worsening shortness of breath over the last 2 days. She has a 40-pack-year smoking history and was diagnosed with chronic obstructive pulmonary disease (COPD) 5 years ago. She uses a daily fluticasone/salmeterol inhaler and a tiotropium inhaler. Her home oxygen saturation is usually 93% on room air. Over the past 48 hours, she has noticed increased cough and a larger volume of sputum, which remains clear to white. She has had no fever, orthopnea, or lower extremity edema. Temperature is 37.0°C (98.6°F), blood pressure is 134/82 mm Hg, pulse is 96/min, and respirations are 22/min. Pulse oximetry is 91% on room air. Pulmonary examination shows a prolonged expiratory phase with scattered wheezes bilaterally. Cardiovascular examination is normal with no murmurs, gallops, or jugular venous distention. There is no peripheral edema. Which of the following is the most appropriate next step in management?

  1. A
    Oral prednisone, nebulized albuterol, and oral azithromycin
  2. B
    Empiric oral levofloxacin and nebulized albuterol
  3. Oral prednisone and nebulized albuterolAnswer
  4. D
    Intravenous furosemide and serum brain natriuretic peptide measurement
  5. E
    Arterial blood gas analysis to calculate metabolic compensation using Winter's formula

Answer

Oral prednisone and nebulized albuterol
The correct answer is oral prednisone and nebulized albuterol. This patient is experiencing a mild to moderate acute exacerbation of COPD in an outpatient setting. Standard management includes short-acting bronchodilators and systemic glucocorticoids (such as a 5-day course of oral prednisone) to reduce airway inflammation. Antibiotics are not indicated here because the patient lacks sputum purulence; guidelines specify antibiotics should only be given if all three cardinal symptoms are present (increased dyspnea, increased sputum volume, and increased sputum purulence), if two symptoms are present but one of them is purulence, or if the patient requires mechanical ventilation.

Step-by-Step Solution

1
Diagnose the patient's acute condition based on the clinical presentation.
The patient has an acute exacerbation of chronic obstructive pulmonary disease (AECOPD).
She has a known history of COPD and presents with acute worsening of dyspnea and an increase in sputum volume, which are hallmark signs of an exacerbation.
2
Evaluate the need for antibiotic therapy using established criteria.
Antibiotics are not indicated at this time.
She exhibits only two cardinal symptoms (increased dyspnea and increased sputum volume) and notably lacks sputum purulence. She also does not require mechanical ventilation.
3
Determine the optimal outpatient medical management.
Initiate systemic glucocorticoids and short-acting bronchodilators.
Oral prednisone and a short-acting beta-agonist (such as albuterol) are proven to improve lung function, enhance oxygenation, and shorten recovery time in AECOPD.

Key Concept

In acute exacerbations of COPD, antibiotics are indicated only if the patient has all three cardinal symptoms (increased dyspnea, increased sputum volume, increased sputum purulence), has two symptoms if one is purulence, or requires mechanical ventilation.
