Monitoring

Symptoms: Dyspnea
1. mMRC Dyspnea Index
2. COPD Assessment Test (CAT Tool)
Exam
1. Pulse Oximetry
2. Timed walking of specific distances
Spirometry
1. Serial FEV1 Measurements are most significant value
2. FEV1 <1 Liter indicates severe disease
3. Poor prognosis if FEV1 <750 cc (<50% predicted)
Goals
1. Decrease Dyspnea
2. Improve quality of life
3. Prevent exacerbations
4. Decrease hospitalizations
5. Slow disease progression and decrease mortality

Prevention

See COPD Exacerbation Prevention
Immunizations
1. Influenza Vaccine yearly
2. Pneumococcal Vaccine (PCV20 or PCV15 and PPSV23)
3. Covid Vaccine
Tobacco Cessation! (and Vaping cessation)
1. Single most important intervention
2. Decreases FEV1 decline and mortality
3. Make use of Smoking Cessation adjuncts (Bupropion, Varenicline, Nicotine Replacement)
4. Educating patients about their lung age (estimated via Spirometry) is effective motivation
  1. Parkes (2008) BMJ 336(7644): 598-600 [PubMed]
Pulmonary Rehabilitation
1. Indicated in moderate to severe COPD with Dyspnea-limited activities or impaired quality of life
2. Includes Pulmonary Rehabilitation Exercise, nutritional counseling, education and behavioral modification
3. Reduces Dyspnea, improves Exercise ability and improves quality of life if continued for at least 6 months
  1. Salman (2003) J Gen Intern Med 18(3): 213-21 [PubMed]

Management
Approach

GOLD Treatment protocols focus on 2 criteria
1. Dyspnea (mMRC Dyspnea Scale, COPD Assessment Test)
2. Exacerbations (based on presence of high risk criteria)
  1. Hospitalizations
  2. Two or more moderate exacerbations
Exacerbations
1. Moderate Exacerbations 0 to 1 (not leading to hospitalization)
  1. Gold A: Fewer Symptoms (mMRC Dyspnea Scale 0 to 1, COPD Assessment Test <10)
    1. Maintain single long-acting Bronchodilator (LABA or LAMA)
  2. Gold B: More Symptoms (mMRC Dyspnea Scale >=2, COPD Assessment Test <10)
    1. Maintain dual therapy (LABA and LAMA)
2. Moderate Exacerbations >=2 (at least one hospitalization): GOLD Group E
  1. Maintain dual therapy (LABA and LAMA)
  2. Use Triple Therapy (add Inhaled Corticosteroid) if indicated as below
  3. Background
    1. GOLD Group E as of 2023 combines prior Groups C and D
    2. Group C included patients with fewer symptoms (mMRC 0-1, CAT<10)
    3. Group D included patients with more symptoms (mMRC >=2, CAT>=10)
Inhaled Corticosteroid
1. Inhaled Corticosteroid examples: Fluticasone (Flovent)
2. Indications (Eosinophilic Inflammation)
  1. Blood Eosinophil Count >300 cells/uL (may consider if count 100 to 300 cells/uL) OR
  2. Comorbid Asthma OR
  3. Two or more COPD exacerbations per year
3. Contraindications
  1. Multiple Pneumonia events
  2. Blood Eosinophil Count <100 cells/uL
  3. Mycobacterial infections
4. Precautions
  1. See Medications in COPD Management for Inhaled Corticosteroid precautions
  2. Corticosteroids increase risk of Pneumonia (NNH 64 for triple therapy compared with dual therapy)
  3. Corticosteroids are not uniformly effective in COPD
    1. Overall, NNT 16 to reduce one exacerbation in 12 months with triple therapy (compared with dual therapy)
    2. Eosinophil Count >300 cells/ul (>4% of total WBC) predicts steroid responsiveness
    3. Unlikely to be steroid responsive if Eosinophil Count <100 cells/ul
    4. Eosinophil Count is only has predictive value when OFF inhaled and Systemic Corticosteroids
    5. COPD may still respond to Systemic Corticosteroids despite low Eosinophil Count

Management
Protocols

Exacerbation Guidelines
1. See Stepped Management as above
2. See Antibiotic Use in COPD Exacerbation
3. Do not define exacerbation severity by Spirometry
4. Consider Chest XRay in hospitalized patients
5. Prednisone 40 mg orally daily (5 day course is typical)
  1. Five day course of 40 mg daily is sufficient for most COPD exacerbations
    1. Leuppi (2013) JAMA 309(21):2223-31 [PubMed]
  2. Ten day course reduces relapse rate after COPD evaluation in ER
    1. Aaron (2003) N Engl J Med 348:2618-25 [PubMed]
6. Avoid low efficacy therapies
  1. Mucolytic medications are not shown helpful
  2. Chest physiotherapy is not efficacious
  3. Theophylline not helpful in exacerbations
7. References
  1. Snow (2001) Chest 119:1185-9 [PubMed]
Maintenance Guidelines
1. Before Intervention
  1. Test Spirometry
  2. Review Patient's symptoms
2. Initiate Trial of Intervention
3. After Intervention
  1. Recheck Spirometry
  2. Were Patient's symptoms improved?

Management
Surgical Interventions

Lung Transplantation
Lung Volume reduction surgery
1. High Risk Surgery (high mortality)
2. Indicated in severe upper lobe predominant Emphysema and low post-Pulmonary Rehabilitation Exercise capacity
3. Improves 5 year survival in severe COPD with heterogeneous distribution of Emphysema and upper lobe predominance
  1. Improved quality of life if BODE Index >5
  2. Sanchez (2010) J Thorac Cardiovasc Surg 140(3): 564-72 [PubMed]
4. Worse prognosis (increased 30 day mortality) if FEV1 <20% predicted, low DLCO or homogenous Emphysema
  1. (2001) N Engl J Med 345(15): 1075-83 [PubMed]

Management
Other Interventions

Phosphodiesterase-4 Inhibitor
1. Reduces pulmonary inflammation by inhibiting breakdown of intracellular cAMP
2. Indicated in severe, refractory COPD with frequent exacerbations
3. Roflumilast (Daliresp) 500 mcg daily
  1. NNT: 24 severe COPD patients to prevent 1 hospitalization per year
  2. Field (2011) Circ Respir Pulm Med 5: 57–70 [PubMed]
4. Ensifentrine (Ohtuvayre)
  1. Combined PED3 and PDE4 Inhibitor nebulized twice daily
  2. Very expensive and efficacy unclear at release in 2024
Longterm Oxygen Therapy
1. Indications
  1. Severe resting Hypoxemia (after breathing room air for 30 minutes)
    1. Partial Pressure of oxygen <=55 mmHg OR
    2. Oxygen Saturation <=88%
  2. Tissue Hypoxia findings (alternative criteria)
2. Efficacy
  1. Decreases mortality in severe resting Hypoxemia
  2. Does not improve outcomes or quality of life in exertional Dyspnea
3. Target
  1. Use for >=15 hours/day
  2. Target Oxygen Saturations 88 to 92%
Beta Blockers (Cardioselective)
1. Recommended in COPD (despite prior relative contraindication in COPD)
2. Cardioselective Beta Blockers (e.g. Metoprolol, Bisoprolol) improve cardiopulmonary status
3. Associated with decreased COPD exacerbations and increased survival
4. Decrease Bronchodilator induced Tachycardia
5. Do not reduce Bronchodilator (beta Agonist) effectiveness

Prophylactic Antibiotics
1. Not routinely recommended
  1. Risk of resistance
  2. Risk of medication adverse effects (e.g. QTc Prolongation with Macrolides)
2. Macrolide Antibiotics reduce COPD exacerbations (NNT 8 to prevent 1 exacerbation in 50 weeks)
  1. Erythromycin 500 mg orally twice daily OR Azithromycin 250 mg daily (or 500 mg three times per week)
  2. No benefit with Tetracycline or fluroquinolone prophylaxis

Management
Excessive upper airway secretions

Mucolytics (e.g. Guaifenesin)
1. Reduces days of illness per month by 1/2 day
2. Doubles chance of being free of exacerbations
3. Poole (2001) BMJ 322:1-6 [PubMed]
N-Acetylcysteine (for thick secretions)
1. Dose: 600-1200 mg/day in divided dosing
2. Decramer (2005) Lancet 365(9470):1552-60 [PubMed]
Intranasal Steroid
1. Consider if considerable airway phlegm
