COPD and antibiotics.

Welcome back to POTD. 

The weekend has come and the weekend has gone. I know you've all been holding your breath to hear about----

A message from our sponsors:

Take a deep inhale. feel some wellness. feel the firmness of your feet on the floor. hold onto your seat.   

Exhale nice and slowly......like someone with a COPD exacerbation.

Because today we're discussing antibiotic coverage in acute COPD Exacerbations. I know you've been waiting a lung time for this one. 

Background

  • Acute COPD exacerbations (AECOPD) account for ~1.5 million ED visits annually in the ED.

  • Many physicians routinely prescribe antibiotic coverage for AECOPD

  • a 2018 review demonstrated antibiotic prescriptions given on 39% of ED visits for AECOPD between 2009-2014.

  • Due to the structural changes in the bronchi of COPD patients they are more prone to bacterial colonization (as opposed to asthmatics - which have no structural change but a reactive process)

Do guidelines exist?

  • Sure do. 

  • if the patient appears infectious (think fever) administer antibiotics. This is understandable given their risk factors and bronchial structural changes.

  • Several guidelines exist for more subtle cases, they exist as follows: (see chart below)

    • Global initiative for Chronic Obstructive Lung Disease:

      • Antibiotics should be given to

        • patients with all 3 of the following cardinal symptom

          1. increased dyspnea

          2. increased sputum volume

          3. increased sputum purulence

        • patients with 2 cardinal symptoms, if there is increased purulence

        • patients requiring noninvasive or invasive ventilation

    • American Thoracic Society/European Respiratory Society

      • hospitalized patients with chanegs in sputum characteristics

      • all patients admitted to an ICU

    • Canadian Thoracic Society

      • patients with severe purulent AECOPD

    • National Institute for Health and Clinical Excellence

      • patients with more purulent sputum

  • Basically, pay attention to that sputum. take a thorough history and discuss changes in sputum production.
