COPD Management Guidelines

Diagnosis and Assessment

The American Thoracic Society recommends spirometric testing for diagnosis, with FEV1/FVC ratio <0.7 confirming airflow limitation 1
COPD severity is classified based on FEV1 percentage of predicted value: mild (60-80%), moderate (40-59%), and severe (<40%) 3
Assessment should include evaluation of symptoms (breathlessness, cough, sputum production) and exacerbation history 1
Blood gas analysis is necessary in severe COPD to identify persistent hypoxemia and/or hypercapnia 3

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommends a stepwise approach based on symptom severity and exacerbation risk, with long-acting bronchodilators (LAMA and/or LABA) as first-line therapy 1, 2
For Group A (Low Symptoms, Low Risk) patients, start with a bronchodilator (short-acting or long-acting) 1
For Group B (High Symptoms, Low Risk) patients, start with a long-acting bronchodilator (LAMA or LABA) 1
For Group C (Low Symptoms, High Risk) patients, start with a LAMA (preferred due to superior exacerbation prevention) 1
For Group D (High Symptoms, High Risk) patients, start with LAMA+LABA combination 1

The American College of Chest Physicians recommends smoking cessation as essential at all stages of disease 3, 4
Pulmonary rehabilitation improves exercise performance and reduces breathlessness 4
Influenza vaccination is recommended for all COPD patients 1
Pneumococcal vaccinations (PCV13 and PPSV23) are recommended for patients >65 years and younger patients with significant comorbidities 1
Nutritional supplementation is recommended for malnourished patients 1
Self-management education including smoking cessation, medication use, dyspnea management, and when to seek help 1

Long-term oxygen therapy is indicated for stable patients with PaO2 ≤55 mmHg or SaO2 ≤88% with or without hypercapnia, confirmed twice over 3 weeks 1
Long-term oxygen therapy is also indicated for patients with PaO2 between 55-60 mmHg or SaO2 of 88% with evidence of pulmonary hypertension, peripheral edema, or polycythemia 1

Increase bronchodilator dose/frequency 5
Add antibiotics if two or more of: increased breathlessness, increased sputum volume, or purulent sputum 5
Consider oral corticosteroids (30mg prednisolone daily for 7 days) in specific cases 5
Hospital admission should be considered based on symptom severity, response to initial therapy, and comorbidities 5

Non-invasive ventilation (NIV) may be considered for patients with pronounced daytime hypercapnia and recent hospitalization 1
Lung volume reduction (surgical or bronchoscopic) may be considered for selected patients with heterogeneous or homogeneous emphysema and significant hyperinflation 1
Lung transplantation may be considered for selected patients with very severe COPD 1

Regular follow-up is essential to monitor disease progression, with spirometry performed opportunistically to detect rapid decline 6
