Management of COPD Exacerbations

Identifying Red Flags and Initial Assessment

  • Severe shortness of breath on any exertion or at rest is a significant red flag indicating severe COPD, according to the Thorax journal 2, 3
  • Development of purulent sputum suggests an infectious exacerbation requiring antibiotic therapy, as recommended by the Thorax journal 4
  • Increased sputum volume is another indicator of an acute exacerbation, as noted in the Thorax journal 4
  • Other concerning signs include cyanosis, peripheral edema, and signs of hypercapnia, such as drowsiness, flapping tremor, and bounding pulse, as indicated in the Thorax journal 3

Treatment Options

  • For mild-moderate exacerbations, increase dose or frequency of short-acting bronchodilators, as recommended by the Thorax journal and Praxis Medical Insights 7, 1
  • Antibiotic therapy is indicated when at least two of the following are present: increased breathlessness, increased sputum volume, and development of purulent sputum, as recommended by the Thorax journal and Praxis Medical Insights 4, 1
  • Systemic corticosteroids improve lung function and shorten recovery time, and should be considered in moderate to severe exacerbations, as recommended by the Thorax journal and Praxis Medical Insights 4, 1
  • Supplemental oxygen should be provided to maintain oxygen saturation >88-92%, as recommended by Praxis Medical Insights 1

Non-Pharmacological Interventions

  • Ensure proper inhaler technique and device selection, as recommended by the Thorax journal 7
  • Consider pulmonary rehabilitation for patients with moderate to severe disease, as recommended by the Thorax journal and Praxis Medical Insights 7, 1
  • Smoking cessation remains essential at all stages of disease, as recommended by the Thorax journal and Praxis Medical Insights 7, 1

Follow-up After Acute Exacerbation

  • If patient treated at home does not improve within two weeks, consider chest radiography and hospital referral, as recommended by the Thorax journal 6
  • For patients discharged from hospital, follow-up assessment 4-6 weeks after discharge should include measurement of lung function, reassessment of inhaler technique, and review of treatment regimen, as recommended by the Thorax journal and Praxis Medical Insights 6, 1
