Module Overview
COPD is a common, preventable, and treatable disease characterized by persistent respiratory symptoms and airflow limitation, usually caused by significant exposure to noxious particles or gases like cigarette smoke. This module provides a primary-care-focused summary of diagnosis and management based on current UK guidelines.
Diagnosis & Assessment
A diagnosis of COPD should be considered in anyone over 35 with a risk factor (usually smoking) and persistent respiratory symptoms. The diagnosis must be confirmed by spirometry.
A post-bronchodilator FEV₁/FVC ratio of less than 0.7 confirms persistent airflow limitation consistent with COPD. The severity of the obstruction (FEV₁ % predicted) is then used to guide management, alongside symptom burden (MRC scale) and exacerbation history.
💊 Pharmacological Management
Pharmacological therapy aims to reduce symptoms, improve exercise tolerance, and prevent exacerbations. The choice of initial therapy is guided by the patient's symptoms and whether they have any features suggesting steroid responsiveness (asthmatic features/atopy). For monitoring details, refer to the SPS Drug Monitoring checker.
NICE Inhaled Therapy Algorithm for Stable COPD
| Step | Therapy | Rationale & Key Points |
|---|---|---|
| Step 1: Reliever | Short-acting β₂-agonist (SABA) or Short-acting muscarinic antagonist (SAMA) as required. | For initial symptom relief. If used regularly, maintenance therapy is needed. SABA (e.g., Salbutamol) or SAMA (e.g., Ipratropium). |
| Step 2: Initial Maintenance (If no asthmatic features) |
Offer a combination LAMA + LABA inhaler. | This is the preferred first-line maintenance treatment for most COPD patients, providing dual bronchodilation. (e.g., Ultibro, Anoro, Spiolto). |
| Step 2: Initial Maintenance (If asthmatic features present) |
Offer a combination LABA + ICS inhaler. | The presence of asthmatic features/steroid responsiveness suggests an Inhaled Corticosteroid (ICS) will be beneficial. (e.g., Fostair, Symbicort, Seretide). |
| Step 3: Escalation | Offer Triple Therapy (LAMA + LABA + ICS) in a combination inhaler. | Used if patients have exacerbations or remain breathless on dual therapy. (e.g., Trelegy, Trimbow, Trixeo). Before stepping up, always check adherence and inhaler technique. |
- Prophylactic Antibiotics: A trial of Azithromycin may be considered by specialists for non-smokers with frequent exacerbations.
- Mucolytics: A trial of Carbocisteine can be considered for patients with a chronic productive cough.
- Theophylline: Rarely used now due to its narrow therapeutic index and side effect profile. Only considered by specialists if other treatments have failed.
Bonus: Clinical Case Study
The Scenario: Escalating Therapy
Patient: Mr. Smith, a 68-year-old ex-smoker with COPD. He has no asthmatic features. He is currently using a LAMA+LABA inhaler but has had two exacerbations requiring oral steroids in the last year.
S (Subjective): Patient reports being more breathless recently and is frustrated by his frequent chest infections. He states he uses his inhaler correctly every day.
O (Objective): Dispensing records confirm good adherence. Inhaler technique check is satisfactory. He has had two exacerbations in the last 12 months.
A (Assessment): The patient is having exacerbations despite being on optimal dual bronchodilator therapy. According to NICE guidelines, he is a candidate for escalation to triple therapy.
P (Plan):
- Medication Change: Recommend switching from his LAMA+LABA inhaler to a single-inhaler triple therapy (LAMA+LABA+ICS), for example, Trelegy Ellipta.
- Counselling: Explain that adding the inhaled steroid component is the next step to help reduce the inflammation in his lungs and prevent flare-ups. Counsel on the importance of rinsing his mouth after using the new inhaler to prevent oral thrush.
- Inhaler Technique: Demonstrate the use of the new inhaler device (e.g., Ellipta) and check his technique.
- Follow-up: Arrange a follow-up review in 4-6 weeks to assess the impact on his symptoms and exacerbation frequency.

🎯 OSCE Preparation
OSCE Station: Counselling on a "Rescue Pack"
Scenario: A 68-year-old patient with severe COPD has been given their first rescue pack containing Prednisolone and Doxycycline. Counsel them on its use.- Acknowledge & Set Context: "Hello, this pack is for you to keep at home so you can start treatment quickly if you have a flare-up, which can help you recover faster."
- Explain the Triggers (When to Start): "You should start the pack if your normal symptoms get significantly worse. The key signs are being more breathless or coughing more, AND your phlegm changing colour to become more yellow or green."
- Provide Clear Instructions: "If that happens, start taking BOTH the steroid tablets and the antibiotic capsules as directed on the labels. It's important to finish the full course of antibiotics."
- Safety Netting: "You must still contact your GP or respiratory nurse the same day you start the pack to let them know. If you feel very unwell, your breathing gets rapidly worse, or you feel confused, you must call 999 immediately."
- Check Understanding (Teach-Back): "To make sure I've been clear, can you tell me in what situation you would start taking the tablets?"
