What the exam tests
Key features
The CFPC’s 9 key features for Chronic Obstructive Pulmonary Disease. Each one below has how the exam asks it, the common mistakes and the approach.
Practice question
Try one before you read
A real case from the bank, in the new short-menu format. Answer it first. Then read the key features.
Key feature 1 of 9
Think of it
Think of COPD in a smoker with a lasting cough, breathlessness or less stamina.
CFPC skill Clinical reasoningPhase Hypothesis generation, diagnosisSources Canadian Thoracic Society, Canadian Task Force on Preventive Health Care
On the exam
A long-time smoker labelled with asthma at a walk-in clinic. Expect a short menu: you pick several answers from a list.
Pick what fits COPD and the test to order.
Common mistakes
Allergy skin tests for the asthma label, or a lung cancer CT at 48. Neither shows blocked airflow. Calling a smoker's cough normal is wrong too.
Approach
- Think of COPD in anyone with a long cough, daily phlegm, breathlessness or less stamina.
- Ask about smoking. Count pack-years: packs a day times years smoked.
- An old asthma label does not settle it. Only spirometry after a bronchodilator does.
- Many people with COPD are never diagnosed. They still have symptoms and still face flare-ups, pneumonia and early death.
- A lung cancer CT answers a different question. It is for adults 55 to 74 with at least 30 pack-years who smoke now or quit under 15 years ago.
Key feature 2 of 9
Prove it
Confirm a suspected diagnosis with spirometry before you label or treat it.
CFPC skill Clinical reasoningPhase InvestigationSources Canadian Thoracic Society, Choosing Wisely Canada
On the exam
A breathless smoker, never tested, recovering from a chest infection. Expect one best answer from a short list.
Pick the test that confirms it.
Common mistakes
A peak-flow diary, a chest X-ray or a methacholine test. None proves fixed airflow blockage. Starting a daily inhaler before the test is wrong too.
Approach
- Order spirometry after a bronchodilator puff. FEV1 is the air blown out in the first second; FVC is the total.
- A ratio of FEV1 to FVC below 0.70 after the bronchodilator confirms COPD.
- Do not start a daily inhaler until spirometry confirms the blockage. Untested patients get side effects and cost for nothing.
- A smoker with symptoms but normal spirometry does not have COPD. A long-acting inhaler does not ease those symptoms.
| Result | What it means | Next step |
|---|---|---|
| FEV1/FVC below 0.70 | COPD confirmed | Grade it by how far FEV1 has fallen |
| FEV1 80% or more of predicted | Mild airflow blockage | Judge symptoms with the CAT (COPD Assessment Test) and mMRC breathlessness scale too |
| FEV1 below 80% of predicted | Moderate or severe blockage | Judge symptoms and flare-up risk to pick inhalers |
| FEV1/FVC 0.70 or more | No COPD | No long-acting inhaler; look for another cause |
Key feature 3 of 9
Track it
Repeat spirometry over the years to see how the disease is changing.
CFPC skill Clinical reasoningPhase Investigation, follow-upSources Canadian Thoracic Society
On the exam
Known COPD, more breathless a year after quitting. Expect a short menu of tests to order and tests to skip.
Pick the tests that guide his care.
Common mistakes
Full lung testing, a blood gas or a methacholine test. The diagnosis is made; the falling FEV1 is what you need. A sputum culture when he is not unwell is wrong too.
Approach
- Repeat spirometry to see how far the post-bronchodilator FEV1 has fallen.
- Never judge severity on spirometry alone. Add symptom scores and his flare-up history.
- Score symptoms with the CAT (COPD Assessment Test) and breathlessness with the mMRC scale.
- A CAT of 10 or more, or an mMRC of 2 or more, means a high symptom burden.
- Count flare-ups in the past year at each visit. That count changes the inhaler plan.
Key feature 4 of 9
Quitting
Help every smoker with COPD to stop smoking.
CFPC skill Clinical reasoning, patient-centred approachPhase TreatmentSources Canadian Thoracic Society
On the exam
A new diagnosis in a man who still smokes. Expect a short menu of first steps.
Pick what belongs in today's plan.
Common mistakes
Writing the inhaler and skipping the talk about smoking. Dropping the subject after one failed attempt is wrong too.
Approach
- Quitting is part of the base plan for every patient, at every stage of COPD.
- Ask about smoking at each visit and say clearly that stopping helps his lungs.
- Offer help to quit at every visit. The Smoking Cessation page covers how.
- Ask what he is ready to do today and set a date if he is willing.
- Follow up soon after the quit date. A slip is a reason to try again, not to stop.
Key feature 5 of 9
Vaccines
Offer the vaccines that protect a person with COPD.
CFPC skill Clinical reasoningPhase TreatmentSources Canadian Thoracic Society
On the exam
A 58-year-old with COPD and a vaccine record. Expect a short menu of vaccines due today.
Pick the vaccines to give today.
Common mistakes
Leaving vaccines out of today's plan because the visit is about his breathing. Vaccines belong in the base plan at every stage of COPD.
Approach
- Vaccines are part of the base plan for every patient with COPD.
- Check his vaccines at diagnosis and at every follow-up visit.
- Use the current national advice to pick the pneumococcal product.
Key feature 6 of 9
Inhalers
Pick the right maintenance inhaler for a person with stable COPD.
CFPC skill Clinical reasoningPhase TreatmentSources Canadian Thoracic Society
On the exam
Confirmed COPD, stops to catch his breath after one block, one hospital stay this year. Expect one best answer from a short list.
Pick the best maintenance inhaler.
Common mistakes
An inhaled steroid with a LABA because his mother had asthma, or one long-acting drug alone for a high-risk patient. A reliever alone, or adding theophylline, is wrong too.
Approach
- Everyone gets a short-acting reliever to use as needed.
- Mild symptoms and FEV1 80% or more: one long-acting bronchodilator, a LAMA (long-acting muscarinic antagonist) or a LABA (long-acting beta-agonist).
- More symptoms and FEV1 below 80%, low flare-up risk: a LAMA/LABA combination.
- High flare-up risk: triple therapy, LAMA/LABA plus an inhaled steroid (ICS), in one inhaler. It lowers the risk of death.
- Use an inhaled steroid with a LABA only if he also has asthma. Never an inhaled steroid alone.
- Still flaring on triple therapy: add azithromycin if the ECG shows a normal QT interval, or roflumilast or N-acetylcysteine for chronic bronchitis. No theophylline, no daily prednisone.
| Group | Who | Start with |
|---|---|---|
| Mild | CAT under 10, mMRC 1, FEV1 80% or more | LAMA or LABA |
| Low flare-up risk | CAT 10 or more or mMRC 2 or more, FEV1 under 80%; up to 1 moderate flare-up, no hospital or ED visit | LAMA/LABA; step up to triple if symptoms persist |
| High flare-up risk | Same symptoms, plus 2 or more moderate flare-ups or 1 needing hospital or the ED | LAMA/LABA/ICS in one inhaler |
Key feature 7 of 9
Who else helps
Send the right people with COPD to rehab and other team members.
CFPC skill Clinical reasoningPhase ReferralSources Canadian Thoracic Society, Choosing Wisely Canada
On the exam
Still breathless on two bronchodilators, SpO2 93% at rest. Expect a short menu of referrals.
Pick the referrals that help him.
Common mistakes
Cardiac rehab because he has diabetes, or home oxygen when he is not low. A lung volume reduction referral for moderate disease is wrong too.
Approach
- Refer to pulmonary rehabilitation when breathlessness persists despite the right inhalers. Combine both.
- Refer to a respiratory educator for inhaler technique and a written action plan for flare-ups.
- Check inhaler technique at each visit. Poor technique looks like failed treatment.
- Do not give oxygen for breathlessness at rest when the oxygen level is normal.
- Surgery or valves to reduce lung volume are only for selected patients with very severe disease.
Key feature 8 of 9
Flare-ups
In a COPD flare-up, look for heart disease, infection, anemia and clots.
CFPC skill Clinical reasoningPhase Hypothesis generation, diagnosisSources Canadian Thoracic Society, Choosing Wisely Canada
On the exam
A flare-up with green phlegm, SpO2 88% and a pulse of 112. Expect a short menu of tests for today.
Pick the tests that change care today.
Common mistakes
A CT for clots before judging the chance of one. Blaming the green phlegm for everything and missing the heart is wrong too.
Approach
- Ask what changed: cough, phlegm colour, breathlessness, chest pain, leg swelling.
- Look for heart trouble. A flare-up raises the risk of heart attack and stroke, most in the first month and for up to a year.
- Think of heart attack, heart failure, pneumonia and anemia. Each can drive or mimic a flare-up.
- Judge the chance of a clot first. In a low-risk patient, a negative sensitive D-dimer rules it out without a scan.
Key feature 9 of 9
Care wishes
In severe COPD, plan care wishes early, record them, and review them over time.
CFPC skill Patient-centred approach, clinical reasoningPhase Treatment, follow-upSources Choosing Wisely Canada, Canadian Thoracic Society
On the exam
Severe COPD, well today, after a hospital stay. Expect a short menu of steps for this visit.
Pick what to do at this visit.
Common mistakes
Waiting until he is in the emergency room on a ventilator. Avoiding the talk because he looks well today is wrong too.
Approach
- Start the talk when he is stable, not in a crisis.
- Ask what matters most to him, and what he would and would not want: a breathing tube, ICU care, a mask ventilator.
- Write his wishes in the chart and share them with the team and his family.
- Name the person who would decide for him if he cannot.
- Revisit after each hospital stay and when his health changes.
- Plan care for comfort as the disease advances. Oxygen does not ease breathlessness at rest when his oxygen is normal.
Flashcards
Answer it first, then check.
KF 2Which spirometry result confirms COPD?
A post-bronchodilator FEV1/FVC below 0.70. No other test confirms it. Source: Canadian Thoracic Society
KF 2A coughing smoker has normal spirometry. Should you start a long-acting inhaler?
No. Without proven airflow blockage, a long-acting inhaler does not ease his symptoms. Source: Canadian Thoracic Society
KF 6FEV1 60%, CAT 18, one moderate flare-up last year. Which inhaler?
A LAMA/LABA combination. One moderate flare-up with no hospital stay is still low risk. Source: Canadian Thoracic Society
KF 6What makes a patient high risk for flare-ups?
Two or more moderate flare-ups, or one needing hospital or the emergency room, in the past year. Source: Canadian Thoracic Society
KF 6When is an inhaled steroid with a LABA the right pair?
When the patient has asthma as well as COPD. Otherwise LAMA/LABA is preferred. Source: Canadian Thoracic Society
KF 7Breathless on two bronchodilators, SpO2 93% at rest. Oxygen or rehab?
Pulmonary rehabilitation. Oxygen does not ease breathlessness at rest when the oxygen level is normal. Source: Choosing Wisely Canada, Canadian Thoracic Society
KF 9When do you start talking about a breathing tube and ICU care?
Early, while he is stable. Write it down and revisit after each hospital stay. Source: Choosing Wisely Canada
FAQ
Which COPD guideline does the exam follow?
The CFPC does not name one. The Canadian Thoracic Society guideline on inhalers for stable COPD is the Canadian standard. Know its groups: symptoms, lung function and flare-up risk.
Is the 0.70 ratio or the lower limit of normal used?
The Canadian guideline confirms COPD with a post-bronchodilator FEV1/FVC below 0.70. It notes the fixed ratio can mislead at the extremes of age, but that is still the line it uses.
Do I need to know blood eosinophil counts?
Only a little. In high-risk patients on triple therapy, Canadian advice is to keep the inhaled steroid. Stopping it does most harm when eosinophils are 300 cells/µL or more. Flare-up history, not eosinophils, drives the first inhaler choice.
