NICE guideline (NG115) Chronic obstructive pulmonary disease in over 16s: diagnosis and management
GOLD
Treat exacerbations promptly with antibiotics if purulent sputum and increased shortness of breath and/or increased sputum volume. In patients with recurrent infections, previous sputum results may be useful to guide antimicrobial choice.
Consider treatment in patients with co-morbidity, aged over 75 years, pyrexia, heart failure, diabetes or stroke. Risk factors for antibiotic resistant organisms include co-morbid disease, severe COPD, frequent exacerbations, antibiotics in last 3 months.
Note: Tetracycline resistance is low in Haemophilus influenzae, a common respiratory pathogen in COPD exacerbations.

Intravenous therapy only required if nil by mouth.
