Important updates

Updated international guidance on diagnosis, treatment, and prevention of COPD

  • The assessment tool, which is used to classify patients into 4 groups (A to D), has been refined to use only respiratory symptoms and history of exacerbations.

  • The pharmacologic management of ongoing COPD has been completely revised, with strategies for escalation and de-escalation of treatment.

  • Inhaled corticosteroids are now only recommended if patients with ongoing COPD experience further exacerbations while on long-acting bronchodilators, or in those with likely asthma-COPD overlap.
