• Characterize disease phenotypes, exacerbation risks, and treatable traits
• Discuss recent clinical trial evidence and guideline updates
• Tailor maintenance regimens for patients with chronic obstructive pulmonary disease (COPD) to reflect disease severity, minimize exacerbation risks, and account for comorbidities and patient preferences
• Learn how to educate patients with COPD
• Heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea, cough, sputum production, exacerbations)
– Due to abnormalities of the airways (bronchitis, bronchiolitis) and/or alveoli (emphysema) that cause persistent, often progressive airflow obstruction
• Focuses on patient characteristics and removes etiology to emphasize COPD factors beyond tobacco
• In low- and middle-income countries, nonsmoking COPD may be responsible to 60%-70% of cases

• REDUCE trial: shorter course of systemic steroids yields equal length to next exacerbation1
• Steroids shorten recovery time, reduce risk of treatment failure, and reduce risk of early relapse
• Preferred dosing of prednisone 40 mg for 5 days

• Controversial, but some evidence of benefit with antibiotics in absence of pneumonia
– Most exacerbations are triggered by viral infection. Bacterial infection or environmental factors can also trigger
– To reduce overexposure to antibiotics, suggest use of antibiotics if increase in dyspnea, sputum volume, and sputum purulence
• Sputum purulence more specific
• Or require mechanical ventilation (invasive or noninvasive)
• Duration: 5 days
• Choice: should be based on local resistance pattern (macrolide, tetracycline, amoxicillin)
– If frequent exacerbations or require mechanical ventilation recommend sputum culture
• Inhaled bronchodilators:
– Increase dose and/or frequency of short-acting bronchodilator
– Combine SABA and short-acting anticholinergics as initial bronchodilator for acute exacerbation
– Use spacers or nebulizer when appropriate
• Oxygen therapy: use minimum flow rate to maintain SpO2 (or PaO2) at an acceptable level, as high FiO2 can result in worsening hypercapnia
• Noninvasive ventilation: first mode for acute respiratory failure to improve gas exchange, reduce work of breathing/need for intubation, decrease hospitalization duration, and improve survival
• Reassess oxygen needs
• PFTs are recommended at 8-12 weeks of discharge (baseline conditions) to establish diagnosis
– Can have significant improvement in FEV1 > 8 weeks after acute exacerbation
• Can consider acute spirometry in hospitalized patient or shortly after discharge to try to reduce overdiagnosis
