Principles of Stewardship:
- Up to 50% of infection-related acute exacerbations are viral. Biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT) may play a role in differentiating, when available.
- Exacerbations of COPD are commonly non-infectious and require optimization of non-antimicrobial therapeutic management.
