Complete Management of COPD
Diagnosis and Confirmation
All patients must have spirometry-confirmed diagnosis with post-bronchodilator FEV1/FVC <0.7 before initiating COPD-specific therapy. 1, 2
- Assess symptom burden using mMRC dyspnea scale (0-4) or CAT score (0-40) 1
- Determine exacerbation risk: count moderate exacerbations (requiring antibiotics/steroids) and severe exacerbations (requiring hospitalization) in past year 1
- Measure blood eosinophil count to guide ICS decisions 3
- Obtain arterial blood gas in severe disease to identify hypoxemia (PaO2 ≤55 mmHg) or hypercapnia 1, 2
Pharmacological Management Algorithm
Low Symptoms (mMRC 0-1, CAT <10) + Low Exacerbation Risk (0-1 moderate exacerbations, no severe exacerbations)
Start with long-acting bronchodilator monotherapy (LAMA or LABA) rather than short-acting agents. 3
- LAMA or LABA are equally effective for this population 3
- Short-acting bronchodilators (SABA/SAMA) are acceptable only for truly intermittent symptoms 3
Moderate-High Symptoms (mMRC ≥2, CAT ≥10) + Low Exacerbation Risk
Initiate LAMA/LABA dual bronchodilator therapy immediately. 3
- Dual therapy provides superior symptom control compared to monotherapy 3
- If already on monotherapy with persistent breathlessness, escalate to LABA/LAMA combination 3
- Consider adding roflumilast if FEV1 <50% predicted with chronic bronchitis phenotype 3, 2
High Exacerbation Risk (≥2 moderate or ≥1 severe exacerbation in past year)
Use blood eosinophils to guide ICS decisions:
Eosinophils ≥300 cells/μL: Start single-inhaler triple therapy (LAMA/LABA/ICS) immediately 3
Eosinophils 100-299 cells/μL: Start LAMA/LABA, consider triple therapy if symptoms persist or exacerbations continue 3
Eosinophils <100 cells/μL: Start LAMA/LABA, do NOT escalate to triple therapy 3
Critical ICS Safety Rules
Never use ICS as monotherapy in COPD—this increases pneumonia risk without benefit. 3
- Withdraw ICS if recurrent pneumonia develops 3
- Do NOT withdraw ICS in patients with eosinophils ≥300 cells/μL, moderate-high symptom burden, and high exacerbation risk 3
- Prescribe single-inhaler combinations when possible to avoid multiple device techniques 3
Non-Pharmacological Management
Smoking Cessation (Essential at All Stages)
Smoking cessation is the single most important intervention, reducing disease progression and mortality. 1, 3, 2
- Offer varenicline, bupropion, or nicotine replacement therapy—these increase long-term quit rates to 25% 3
- Reassess and offer cessation support at every visit 2
Pulmonary Rehabilitation
Refer all symptomatic patients (mMRC ≥1) to pulmonary rehabilitation. 1, 3, 2
- Combines exercise training (constant load or interval training) with strength training 3
- Improves exercise performance, reduces breathlessness, and may reduce readmissions 3, 2
- Critical timing: Do NOT initiate before hospital discharge after exacerbation—this may compromise survival 3
- Wait until patient is stable, then refer within 3-4 weeks post-discharge 3
Vaccinations
Administer influenza vaccine annually to all COPD patients. 3, 2
Administer pneumococcal vaccines (PCV13 and PPSV23) to all patients ≥65 years and younger patients with significant comorbidities. 3, 2
Long-Term Oxygen Therapy (LTOT)
Prescribe LTOT for patients with resting hypoxemia to improve survival: 3, 2
- PaO2 ≤55 mmHg or SaO2 ≤88% (with or without hypercapnia), confirmed on two occasions 3 weeks apart 3, 2
- PaO2 55-60 mmHg or SaO2 88% with evidence of pulmonary hypertension, peripheral edema, or polycythemia 3, 2
- Prescribe oxygen at flow rate to maintain SaO2 ≥90% for ≥15 hours daily 2
Self-Management Education
Provide comprehensive self-management education at every visit: 1, 2
- Optimize inhaler device technique and reassess regularly 1
- Assess medication adherence 1
- Teach breathing and cough techniques 1
- Provide written action plan for early recognition and treatment of exacerbations 1
- Promote physical activity and healthy diet 1
Nutritional Support
Provide nutritional supplementation for malnourished patients (BMI <21 or unintentional weight loss). 3, 2
Management of Acute Exacerbations
Community Management
Increase bronchodilator dose/frequency immediately. 1
Prescribe antibiotics if patient has ≥2 of the following: 1
- Increased breathlessness
- Increased sputum volume
- Development of purulent sputum
Add oral corticosteroids (30 mg prednisolone daily for 7 days) if: 1, 3
- Patient already on oral corticosteroids 1
- Previously documented response to oral corticosteroids 1
- Airflow obstruction fails to respond to increased bronchodilator dose 1
- First presentation of airflow obstruction 1
Hospital Admission Criteria
Admit patients with: 1
- Severe breathlessness at rest or with minimal exertion 1
- Cyanosis or confusion 1
- Peripheral edema (new or worsening) 1
- Inability to cope at home despite treatment 1
- Significant comorbidities 1
- Frequent recent admissions 1
Inpatient Management
Administer systemic corticosteroids—these improve lung function, oxygenation, and shorten recovery time. 3
Use non-invasive ventilation (NIV) as first-line for acute respiratory failure in COPD. 3
Do NOT use methylxanthines—side effects outweigh benefits. 3
Advanced Therapies for Severe Disease
Non-Invasive Ventilation (NIV)
Consider home NIV for patients with pronounced daytime hypercapnia (PCO2 >50 mmHg) and recent hospitalization. 3, 2
- Evidence is contradictory; select patients carefully 3
Lung Volume Reduction
Refer selected patients with heterogeneous or homogeneous emphysema and significant hyperinflation refractory to optimized medical care for: 3, 2
- Surgical lung volume reduction surgery (LVRS) 3
- Bronchoscopic lung volume reduction (endobronchial one-way valves or lung coils) 3
Lung Transplantation
Refer for transplant evaluation if: 3
- Progressive disease not candidate for lung volume reduction 3
- BODE index 5-6 3
- PCO2 >50 mmHg or PaO2 <60 mmHg 3
- FEV1 <25% predicted 3
Alpha-1 Antitrypsin Deficiency
Prescribe alpha-1 antitrypsin augmentation therapy for patients with severe hereditary deficiency and established emphysema. 3
Refractory Dyspnea
Consider low-dose long-acting oral or parenteral opioids for severe refractory dyspnea in advanced disease. 3
Ongoing Monitoring and Follow-Up
- Symptom burden (mMRC, CAT score) 1
- Exacerbation frequency and severity 1
- Inhaler technique and adherence 1
- Smoking status 2
- Development of comorbidities 3
- Need for therapy escalation or de-escalation 3
Perform spirometry opportunistically to detect rapid decline. 2
Discuss advance care planning and end-of-life care preferences in severe disease. 1
Common Pitfalls to Avoid
- Do NOT prescribe ICS-containing regimens to low-risk patients without exacerbation history 3
- Do NOT use multiple inhaler devices with different techniques—this increases exacerbations and medication errors 3
- Do NOT delay triple therapy in high-risk exacerbators with eosinophils ≥300 cells/μL—this delays mortality benefit 3
- Do NOT start pulmonary rehabilitation before hospital discharge—wait until patient is stable 3
- Do NOT ignore blood eosinophil counts, particularly at extremes (<100 or ≥300 cells/μL) 3
