πŸ“‹ Clinical Stem β€” Progressive Breathlessness in a Smoker
A 63-year-old male ex-smoker presents with 6 months of progressive breathlessness and morning cough β€” differentiate COPD, heart failure, and lung cancer
"Mr David Hartley, 63 years old, retired plumber. He presents with a 6-month history of gradually worsening breathlessness on exertion β€” he can now manage only one flight of stairs before stopping (MMRC grade 2–3). He has a morning productive cough, worse in winter. He smoked 25 cigarettes a day for 30 years (37.5 pack-years) and stopped 5 years ago. He has a BMI of 31 and hypertension treated with amlodipine 10 mg and ramipril 5 mg. He drinks 20 units of alcohol weekly. He has not had a chest X-ray in 10 years. He came today because his wife made him β€” he has been minimising his symptoms."
Heavy smoking history (37.5 pack-years) with progressive exertional dyspnoea and productive morning cough is COPD until proven otherwise. However, with hypertension and alcohol misuse, alcoholic cardiomyopathy and heart failure must be in the differential. The absence of a chest X-ray for 10 years in a 37.5-pack-year smoker requires urgent consideration of lung cancer. All three diagnoses can coexist.
Scenario A β€” COPD 58-year-old smoker (45 pack-years), productive morning cough, wheeze, breathless on exertion. Spirometry: FEV₁/FVC 0.58 post-BD. GOLD stage 2. Smoking cessation, SABA + LAMA, pulmonary rehab referral.
Scenario B β€” Heart Failure 70-year-old with IHD and hypertension, orthopnoea, PND, ankle oedema, bibasal crackles. BNP elevated. Echo: LVEF 30%. ACEi + beta-blocker + loop diuretic; cardiology referral.
Scenario C β€” Asthma (new diagnosis) 35-year-old with episodic wheeze, nocturnal symptoms, occupational trigger (hairdresser). FEV₁ reversibility 18% post-salbutamol. ICS + SABA; occupational asthma referral if workplace-related.
Scenario D β€” Pulmonary Embolism 54-year-old woman, sudden-onset breathlessness, pleuritic chest pain, unilateral leg swelling, recent long-haul flight. Wells score 7 β€” high probability. D-dimer not needed; CTPA urgently.
Scenario E β€” Lung Cancer 67-year-old smoker with haemoptysis, weight loss 5 kg in 3 months, persistent cough change, breathlessness. 2-week-wait referral β€” CT chest and urgent respiratory review.
Key variables to adapt Age, smoking history, onset (sudden vs insidious), associated features (orthopnoea, pleuritic pain, haemoptysis, weight loss), occupation, pattern of breathlessness (exertional vs nocturnal vs positional), response to previous bronchodilators, SpOβ‚‚, spirometry results.

History Taking β€” Open Question First Β· Targeted Questions Β· ICE Β· Psychosocial Context
β–²collapse
Breathlessness is one of the most symptom-rich presentations in primary care β€” the cause is frequently diagnosable from the history alone if the right questions are asked. The key characterisation axes are: onset (sudden = PE/pneumothorax vs insidious = COPD/HF/malignancy), pattern (exertional = COPD/HF vs nocturnal = HF/asthma vs positional = HF/pleural effusion), associated symptoms (productive cough = COPD/infection; haemoptysis = malignancy/PE; ankle oedema = HF; weight loss = malignancy/severe COPD), and smoking history (pack-years).
πŸŽ“ Consultation opener
"I can see you've had a cough and breathlessness for some months now. Before I ask you anything specific, I'd like to hear it in your own words β€” can you describe what the breathlessness is like and when it first started?"
1A β€” Characterise the breathlessness: onset, pattern, severity, associations
Question to askWhy it matters clinicallyChanges what?
🟒 OPEN QUESTION"Can you describe the breathlessness in your own words β€” when it started, what brings it on, and what makes it better?" Allows the patient to lead with their most troubling aspect β€” often revealing the diagnosis through the spontaneous description of onset, triggers, and associated symptoms before structured questioning begins.A patient who spontaneously describes "I have to sleep sitting up now" has just told you this is likely heart failure. DiagnosesICE
How did it start?"Did it come on suddenly one day, or has it been getting gradually worse over weeks or months?" Sudden onset (hours to days): PE, pneumothorax, pneumonia, acute heart failure. Insidious progressive (weeks to months): COPD, HF developing over time, malignancy, pleural effusion. The timescale is one of the single most discriminating features for the underlying cause.Sudden onset breathlessness at rest β†’ always consider PE, even without traditional risk factors. Wells score should be calculated for any acute-onset unexplained breathlessness. DDxRisk
What brings it on?"Is it only with activity, or do you get it at rest? How far can you walk on flat ground before you have to stop?" Exertional dyspnoea only β†’ COPD, HF, IHD, anaemia. Dyspnoea at rest β†’ severe disease of any cause, or acute presentation. Quantifying exercise tolerance (how many flights of stairs? how far on the flat?) gives the MMRC dyspnoea grade, which guides referral and treatment decisions.MMRC grade 3 (stops after walking 100 metres on flat) = significant limitation β†’ spirometry + pulmonary rehab referral if COPD confirmed. MMRC grade 4 (breathless when dressing) = urgent assessment. DDxReferral
Does position affect it?"Do you get breathless at night β€” can you lie flat comfortably, or do you need extra pillows?" Orthopnoea (breathlessness when lying flat) and PND (waking at night gasping) are specific features of heart failure β€” fluid redistribution from the legs to the pulmonary circulation when supine increases pulmonary venous pressure. The number of pillows needed quantifies orthopnoea severity.Three or more pillows to sleep = almost certainly heart failure until proven otherwise. Orthopnoea has a specificity of over 85% for HF among breathless patients in primary care. DDx HFBNP
Any cough?"Do you have a cough? Is it productive? What colour is the sputum? Any blood in it at any point?" Chronic productive morning cough = COPD or chronic bronchitis. Frothy pink sputum = acute pulmonary oedema (emergency). Frank haemoptysis = malignancy, PE, TB, or bronchiectasis β€” always requires urgent investigation. Blood-streaked sputum = less specific but still warrants CXR and follow-up.Haemoptysis in a patient with over 30 pack-years smoking history = 2-week wait lung cancer referral unless a more obvious benign cause is confirmed. Emergency if pink frothy2ww if haemoptysis
Any wheeze?"Do you or your family notice a whistling sound when you breathe out, particularly at night or first thing in the morning?" Wheeze on expiration suggests airway narrowing β€” asthma (variable, worse at night/morning, reversible with bronchodilators) or COPD (persistent, less variable). Nocturnal and morning wheeze with variation is more characteristic of asthma. Persistent non-variable wheeze in a smoker = COPD.A fixed monophonic wheeze over one area may indicate an obstructing bronchial lesion β€” lung cancer until excluded on imaging. Asthma vs COPD vs obstruction
Ankle swelling or weight gain?"Have your ankles been swelling β€” particularly in the evenings? Have you noticed your weight going up recently?" Bilateral ankle oedema + breathlessness = heart failure until proven otherwise. Rapid weight gain (2+ kg in a week) indicates fluid retention in heart failure decompensation. Note: peripheral oedema alone can also be caused by medication (amlodipine β€” in this case stem), venous insufficiency, or hypoalbuminaemia.The combination of orthopnoea + ankle oedema + elevated JVP is the clinical triad most specific for heart failure β€” each alone is non-specific. HFDiuretic
Any chest pain?"Any chest pain or tightness β€” particularly with the breathlessness?" Pleuritic chest pain (sharp, worse on inspiration and coughing) = PE, pleuritis, or pneumonia. Central crushing chest pain = ACS driving the breathlessness. Chest pain with cough and fever = pneumonia. Pain character differentiates the diagnoses: pleuritic vs ischaemic vs musculoskeletal.Sudden-onset breathlessness + pleuritic chest pain + unilateral leg swelling = PE until proven otherwise β†’ Wells score; CTPA if high probability. PE or ACS β†’ emergencyDDx
Weight change?"Have you noticed your weight changing β€” either gaining weight or losing weight β€” in the last few months?" Unexplained weight loss of over 5% in 3 months in a heavy smoker is a red-flag symptom for lung malignancy until proven otherwise β€” requires urgent 2-week-wait referral. Paradoxically, cachexia in severe COPD also causes weight loss. Weight gain suggests fluid retention (HF).Weight loss + smoking history + breathlessness change = urgent 2-week-wait referral even if the breathlessness seems explicable by COPD. 2ww cancerDDx
Smoking history β€” pack-years"How long did you smoke for and how many cigarettes a day? [pack-years = (cigs/day Γ· 20) Γ— years smoked]" Pack-years is the most important risk stratification tool for COPD, lung cancer, and cardiovascular disease in primary care. Over 20 pack-years + symptoms = spirometry mandatory. Over 30 pack-years + haemoptysis or persistent cough change = 2-week-wait. Quantifying pack-years precisely also validates the importance of smoking cessation as the most impactful single intervention.37.5 pack-years (25/day Γ— 30 years) puts this patient in the high-risk COPD category and requires lung cancer active surveillance consideration. DDx2ww + spirometryCessation
Occupational history"What did you do for work β€” were you exposed to any dusts, chemicals, asbestos, or fumes?" Occupational exposures are a major and under-recognised cause of respiratory disease: asbestos exposure (plumber, shipbuilder, construction) β†’ mesothelioma and asbestosis; coal dust β†’ pneumoconiosis; silica dust β†’ silicosis; isocyanates (spray painting) β†’ occupational asthma. A retired plumber has a specific asbestos exposure risk requiring mesothelioma consideration.A plumber who worked before 1980 likely had regular asbestos pipe-lagging exposure β€” mesothelioma latency is 20–50 years, making this patient's age and occupation a live risk combination.

Even a single episode requires urgent investigation.2-week-wait urgent referral

FactorWhy it mattersManagement impact
Beta-blockersBeta-blockers cause bronchoconstriction in susceptible individuals β€” can precipitate wheeze and breathlessness in asthma or severe COPD. Even cardioselective beta-blockers are relatively contraindicated in severe asthma.Review if asthma confirmed; switch to calcium channel blocker or ACEi for hypertension if beta-blocker is contraindicated
ACE inhibitors (dry cough)ACEi cause a dry persistent cough in up to 15% of patients β€” can be mistaken for asthma or COPD. The cough begins within weeks of starting and resolves completely within 1–4 weeks of stopping.Stop ACEi if cough is ACEi-likely; switch to ARB; recheck cough at 4 weeks

πŸ’­ Ideas
"What do you think might be causing this breathlessness β€” have you had any thoughts about what's going on?"
A 63-year-old ex-smoker may believe "it's just the smoking catching up with me" β€” this stoic attribution model, while partially correct, may prevent him from engaging with investigation of more sinister pathology. The patient who minimises symptoms often has the most important things to find on investigation. Understanding his attribution model is essential to calibrating your explanation.
😟 Concerns
"Is there something specific you've been worried this might be β€” something your wife or family have said, or that's been on your mind?"
The hidden concern in a heavy smoker with breathlessness is often cancer β€” but it may be framed as "I don't want to know." Understanding whether the patient is minimising to avoid confronting a feared diagnosis is essential to the therapeutic relationship. Named and addressed directly, this concern can be pivoted into a reason to investigate rather than a reason to avoid investigation.
🎯 Expectations
"What were you hoping we might do about this today β€” was there something specific you were expecting?"
A patient who was "made to come" by his wife may be coming simply to satisfy her rather than expecting active investigation. Understanding this expectation allows the GP to engage the patient directly in the rationale for investigation β€” making clear that the investigation is for him, not for her. This transforms a reluctant attender into an engaged patient.
1E β€” Psychosocial context
🚬 Smoking, Identity, and Guilt

Many long-term smokers carry significant guilt about their smoking history when they develop respiratory disease. This guilt can paradoxically prevent early presentation ("I've only got myself to blame") and create barriers to engaging with investigation and treatment. Addressing smoking non-judgementally β€” acknowledging that addiction is a disease, not a moral failure β€” is essential to building therapeutic alliance.

"A lot of people feel guilty about their smoking history when they develop a chest problem β€” but addiction is really difficult to overcome, and what matters now is what we do going forward."
πŸ‘΄ Symptom Minimisation β€” Stoic Male

Older adult males are statistically the most likely to minimise respiratory symptoms and delay presentation β€” often attending only when a partner insists. A retired plumber who "doesn't make a fuss" may have been significantly symptomatic for years before attending. The relationship with the patient's wife is an important therapeutic lever β€” with his permission, involving her in the management plan can significantly improve follow-through and monitoring.

"I can see you've been putting up with this for a while. Would it be helpful if your wife was part of the conversation about what we're going to do next β€” since she knows you well and clearly cares about you?"
🚢 Activity Limitation and Loss of Role

Progressive breathlessness causes dramatic and often invisible disability β€” the inability to walk upstairs, garden, or play with grandchildren has profound effects on identity, mood, and self-worth, particularly in retired adults whose physical activity was previously central to their life. Acknowledging this impact opens the conversation about pulmonary rehabilitation and the evidence that physical function can be meaningfully improved even in severe COPD.

"How has the breathlessness been affecting what you're able to do day-to-day β€” things you used to enjoy? I'm asking because there are things we can do to help with that, not just the breathlessness itself."
🍺 Alcohol and Self-Medication

20 units of alcohol per week is above the NICE recommended maximum. In the context of breathlessness, this is clinically significant for two reasons: alcohol can cause cardiomyopathy (directly relevant to HF as a differential), and alcohol misuse may be a coping mechanism for the anxiety, disability, or loss of identity driven by progressive breathlessness and retirement.

"I'd like to ask about alcohol β€” not to judge, but because it can actually affect the heart and lungs, and understanding it helps us figure out what's going on. How much would you say you drink in a typical week?"
🏠 Housing and Environmental Factors

Damp housing, mould exposure, indoor fuel combustion (solid fuel stoves), and outdoor air pollution are all environmental precipitants that can worsen COPD and asthma. For a patient who worked as a plumber, current exposures (DIY, hobbies) may continue to expose him to irritants that are aggravating his respiratory disease.

"Is there anything at home β€” damp, mould, dust from DIY, or a wood-burning stove β€” that might be making the breathlessness worse?"
πŸ’Š Medication Adherence and Inhaler Technique

Breathlessness inadequately controlled by inhalers is one of the most common problems in respiratory disease management β€” and poor inhaler technique is the most common unaddressed cause. Before escalating therapy, always assess inhaler technique and adherence directly, using a demonstrate-then-check-back approach.

"Do you have any inhalers at home? It would be really helpful to see how you use them β€” not to test you, but because technique makes a massive difference to how well they work."

Breathlessness triage begins with a single question: is this patient safe to complete a full consultation in primary care, or does acute hypoxaemia, haemodynamic compromise, or an obstructed airway require immediate action? Once safety is confirmed, the decision tree is driven by the pace of symptom onset, the red flag features identified in the history, and the SpOβ‚‚ on pulse oximetry.

Do I Need This Examination?
β–²collapse
Pulse oximetry and respiratory rate are the two most important and quickest measurements in breathlessness β€” they must be done first, before the physical examination. SpOβ‚‚ under 94% changes the management immediately, regardless of the history. Auscultation differentiates wheeze (obstructive disease), crackles (HF or fibrosis), and reduced or absent breath sounds (effusion, pneumothorax). JVP assessment is one of the most specific clinical signs for heart failure and is frequently omitted in primary care.
ExaminationWhy it mattersKey finding + actionMandatory?
Pulse oximetry (SpOβ‚‚)The single most important measurement in breathlessness β€” an objective marker of severity that bypasses subjective reporting and triggers immediate action if abnormal. Should be done within the first 2 minutes of seeing any breathless patient.Target SpOβ‚‚ 94–98% for most patients. For known COPD with suspected type 2 respiratory failure risk: target 88–92% to avoid hypoxia-driven respiratory drive suppression.Under 88% β†’ oxygen + 999. 88–94% β†’ urgent same-day assessment. Over 94% at rest β†’ doesn't exclude disease on exertionYES β€” immediately
Respiratory rateElevated respiratory rate (over 20 breaths/min) is an early and sensitive marker of respiratory compromise β€” more sensitive than SpOβ‚‚ for early deterioration. It forms part of the CRB-65 severity score for pneumonia and the NEWS2 scoring system for acute illness.A resting RR over 25 breaths/min in a breathless patient indicates significant acute illness β€” do not allow this patient to leave the surgery without a clear safety plan.Over 25/min β†’ significant acute illness; CRB-65 severity scoring; consider same-day admissionYES β€” always
Chest auscultationDifferentiates the three major breathlessness patterns: wheeze on expiration (COPD, asthma), bibasal crackles (HF, interstitial fibrosis), reduced or absent breath sounds with dullness to percussion (effusion, collapse, consolidation). A normal auscultatory finding does not exclude significant respiratory disease.Bilateral fine end-inspiratory crackles + breathlessness + ankle oedema = HF triad. Unilateral reduced breath sounds with stony dull percussion = effusion until proven otherwise.Wheeze β†’ COPD/asthma pathway. Bibasal crackles β†’ BNP; echo. Reduced unilateral β†’ CXR urgently; possible effusion or malignancyYES β€” always
JVP assessmentElevated jugular venous pressure (over 4 cm above the sternal angle at 45Β°) indicates raised right heart filling pressure β€” one of the most specific signs for volume overloaded heart failure. Frequently overlooked in primary care. Combine with ankle oedema and crackles for the most specific HF triad.Hepatojugular reflux (JVP rises when you press on the upper abdomen) is even more sensitive for HF than resting JVP elevation.Elevated JVP β†’ HF most likely; BNP urgently; loop diuretic; cardiology referralYES in HF query
Ankle oedema assessmentBilateral pitting ankle oedema + breathlessness = HF until proven otherwise β€” although amlodipine in the current stem causes non-pitting peripheral oedema as a common side effect. Distinguish pitting (fluid overload/HF) from non-pitting (medication, lymphoedema, chronic venous insufficiency).Unilateral leg swelling in a breathless patient = DVT/PE until proven otherwise β†’ Wells score for DVT; urgent D-dimer or ultrasound.Bilateral pitting β†’ BNP; HF pathway. Unilateral β†’ Wells score; DVT/PE exclusion urgentlyYES β€” always
Peak expiratory flow rate (PEFR)In acute breathlessness: PEFR under 50% predicted = moderate-severe asthma; under 33% = life-threatening. In new breathlessness with suspected asthma: 2-week PEFR diary (morning and evening) showing over 20% variability is highly diagnostic for asthma without requiring formal spirometry.Note: PEFR is effort-dependent and unreliable in COPD β€” spirometry with FEV₁/FVC ratio is the diagnostic gold standard for COPD.PEFR under 50% predicted β†’ acute moderate asthma; intensify treatment and review. Over 20% variability on diary β†’ asthma diagnosed clinicallyAsthma query
Calf tenderness and swellingUnilateral calf swelling, warmth, and tenderness in a breathless patient raises DVT + PE as a combined diagnosis β€” even in the absence of classic DVT symptoms. Add 3 points to the Wells PE score for clinical DVT signs.Up to 40% of PE cases have no identifiable DVT on ultrasound β€” the absence of calf signs does not exclude PE.Positive β†’ Wells PE score +3; high Wells β†’ CTPA without D-dimer; anticoagulate immediately if PE confirmedPE query

Step 4
Do I Need This Investigation?
β–²collapse
The investigative priority in breathlessness is determined by the most dangerous cause that remains on the differential. For this patient: spirometry to confirm or exclude COPD, CXR to look for malignancy/effusion/consolidation/cardiac enlargement, BNP to screen for heart failure, and a full blood count to exclude anaemia. For any patient where PE remains possible after history and examination: Wells score determines whether D-dimer or direct CTPA is the next step.
InvestigationClinical question it answersKey result + action
Spirometry (post-bronchodilator)The only test that can diagnose COPD β€” FEV₁/FVC under 0.7 post-bronchodilator confirms fixed airflow obstruction. Also distinguishes COPD from asthma (reversibility: over 15% and 200 mL improvement post-BD = asthma; FEV₁/FVC normalises in asthma). GOLD staging determines treatment and monitoring intensity.FEV₁/FVC under 0.7 + FEV₁ 50–79% = GOLD stage 2 COPD β†’ SABA + LAMA + pulmonary rehab. FEV₁/FVC under 0.7 + FEV₁ under 30% = GOLD 4 β†’ urgent respiratory referral
Chest X-ray (CXR)Essential first-line imaging for breathlessness β€” hyperinflation + flattened diaphragms (COPD), cardiomegaly + pulmonary oedema (HF), pleural effusion, consolidation (pneumonia), mass lesion (malignancy), pleural plaques (asbestos exposure). A normal CXR significantly reduces the probability of many causes but does not exclude early malignancy.Mass lesion or pleural effusion in a smoker β†’ 2-week-wait CT chest + urgent respiratory referral. Cardiomegaly + bilateral haziness β†’ HF confirmed; BNP; diuretic. Normal CXR + wheeze β†’ spirometry; PEFR diary
BNP / NT-proBNPThe most sensitive blood test for heart failure β€” NT-proBNP over 400 pg/mL makes HF likely; under 100 pg/mL effectively excludes it (in untreated patients). More sensitive than CXR for early HF and is the NICE-recommended first-line investigation for suspected HF before echocardiogram. Affected by renal function, atrial fibrillation (elevates BNP independent of HF), and obesity (suppresses BNP).NT-proBNP over 2000 pg/mL β†’ urgent (within 2 weeks) echocardiogram + cardiology. Over 400 pg/mL β†’ echocardiogram within 6 weeks. Under 100 pg/mL (untreated) β†’ HF unlikely; look for other cause
FBCAnaemia is a significant and under-recognised contributor to breathlessness β€” haemoglobin under 100 g/L can cause exertional dyspnoea as the presenting or principal symptom. Also identifies polycythaemia (secondary to COPD), neutrophilia (infection), and eosinophilia (asthma, eosinophilic pneumonia).Hb under 100 g/L β†’ investigate and treat underlying cause; reassess breathlessness after correction. Eosinophilia + wheeze β†’ consider eosinophilic asthma; check serum IgE
Wells PE Score calculationThe Wells clinical decision rule for PE stratifies probability into low (<2), intermediate (2–6), and high (>6). Low probability β†’ D-dimer (high sensitivity, rules out if negative). High probability β†’ CTPA directly without D-dimer (D-dimer will be positive non-specifically at high Wells, so the negative predictive value is lost).Wells over 6 β†’ CTPA without D-dimer; start therapeutic LMWH immediately pending scan if no contraindication. Wells 2–6 β†’ D-dimer; if positive β†’ CTPA. Wells under 2 + D-dimer negative β†’ PE excluded clinically
D-dimer (only if Wells low to intermediate)D-dimer is a fibrin degradation product β€” highly sensitive but poorly specific for PE (positive in infection, inflammation, malignancy, pregnancy). Only useful when Wells score is low to intermediate β€” its negative predictive value is over 98% in low-probability patients, making it an excellent rule-out test in that context only.D-dimer negative + low Wells β†’ PE excluded. D-dimer positive + any Wells β†’ CTPA required. Never use D-dimer in high Wells-score patients β€” it will be positive and adds no information, delays CTPA
EchocardiogramConfirms heart failure and quantifies severity β€” LVEF, wall motion abnormalities, valvular disease, pulmonary pressures. Mandatory for all patients with new HF diagnosis (NICE NG106); required before starting HFrEF-specific treatment (beta-blocker, spironolactone). Should be done within 2 weeks if NT-proBNP over 2000 pg/mL.LVEF under 40% = HFrEF β†’ ACEi + beta-blocker + MRA; ICD assessment. LVEF over 50% = HFpEF β†’ treat comorbidities; diuretics for symptoms; cardiology
U&E + LFTsBefore starting ACEi/ARB for HF: baseline renal function mandatory (can precipitate acute kidney injury). Before loop diuretics: electrolyte baseline. Elevated LFTs in breathlessness context may suggest right heart failure causing hepatic congestion.Creatinine over 150 Β΅mol/L β†’ renal impairment; adjust ACEi dose; monitor closely.

Reaching a Diagnosis & DDx β€” Explained in Plain Language
β–²collapse
πŸ—£οΈ Explaining Breathlessness in Plain Language β€” say something like this

"The breathlessness you've been experiencing is happening because your airways or your lungs are not working quite as efficiently as they should. In your case, the most likely cause β€” given your smoking history and the type of breathlessness you're describing β€” is a condition called COPD, where years of smoke exposure have caused permanent changes to the small airways in the lungs, making it harder to push air out when you breathe. Think of it like trying to squeeze air through a tube that's narrowed and a bit floppy. The good news is that COPD is manageable, and there are very effective treatments that can significantly improve how much you can do. But I also want to make sure we check a few other things alongside this, because the breathlessness could be coming from more than one place at once β€” and that's why I'm arranging the breathing test, the chest X-ray, and the blood tests."

A β€” Diagnosable in Primary Care
GP can diagnose

COPD (post-bronchodilator FEV₁/FVC <0.7)

Progressive exertional dyspnoea + chronic productive cough in a smoker. Confirmed on spirometry β€” post-bronchodilator FEV₁/FVC under 0.7. GOLD staging guides treatment intensity. Reversibility under 15% distinguishes from asthma. Treatment: smoking cessation, SABA, LAMA, pulmonary rehab.

Asthma

Episodic breathlessness + wheeze with diurnal variation (worse at night and morning) and reversibility (over 15% FEV₁ improvement post-BD). PEFR variability over 20% diagnostic on diary. Triggers: allergens, cold air, exercise, occupational. Treatment: ICS + SABA stepped approach per BTS/SIGN 2023.

Heart Failure (with GP initiation)

NT-proBNP over 400 + echo confirming LVEF under 40% (HFrEF). GP can initiate ACEi + beta-blocker + loop diuretic while echocardiogram is pending if clinical diagnosis is clear. NICE NG106 recommends echocardiogram within 2 weeks for BNP over 2000 pg/mL.

B β€” Suspected β€” Refer
Refer for confirmation

Lung Cancer

Haemoptysis, unexplained weight loss, persistent cough change, or new breathlessness in a smoker over 40 = 2-week-wait referral. Even in the presence of COPD, a new cancer can coexist. CT chest with contrast is the diagnostic imaging of choice β€” not plain CXR (normal CXR does not exclude early lung cancer).

Mesothelioma

Former plumber with asbestos exposure + breathlessness + pleural plaques on CXR = mesothelioma until proven otherwise. CT chest + respiratory referral urgently. Latency 20–50 years makes this presentation age-appropriate. Compensation via IIDB/AFCS may be applicable.

Pulmonary Fibrosis (IPF)

Progressive exertional dyspnoea + fine bibasal Velcro crackles + clubbing in an older adult. HRCT chest is diagnostic. Antifibrotic agents (nintedanib, pirfenidone) under specialist care. Refer to respiratory specialist urgently β€” early treatment slows progression.

Severe / Very Severe COPD (GOLD 3–4)

FEV₁ under 50% predicted requires respiratory specialist input for optimised triple inhaler therapy, pulmonary rehab referral, home nebuliser assessment, and long-term oxygen therapy (LTOT) assessment if SpOβ‚‚ under 92% on air.

C β€” Emergency β€” Act Now
Diagnose & act

Pulmonary Embolism (massive or submassive)

Haemodynamic instability + acute breathlessness + Wells high probability = massive PE β†’ systemic thrombolysis consideration in hospital. Submassive PE (stable with right heart strain on echo) β†’ CTPA + anticoagulation + specialist input. 999 if ongoing haemodynamic compromise.

Acute Severe / Life-Threatening Asthma

PEFR under 33% predicted, SpOβ‚‚ under 92%, silent chest, exhaustion, or bradycardia = life-threatening asthma. Oxygen 15 L/min; nebulised salbutamol 5 mg + ipratropium 500 mcg; IV/IM hydrocortisone; 999 if not responding in 15 minutes.

Acute Pulmonary Oedema (HF decompensation)

Frothy pink sputum + severe breathlessness + SpOβ‚‚ dropping = flash pulmonary oedema. Sit upright; GTN spray (if systolic over 90); furosemide 40–80 mg IV if available; 999. BiPAP in hospital. Mortality up to 10% if not treated immediately.

New heart failure (NT-proBNP over 2000 pg/mL)Echo within 2 weeks (NICE NG106)BNP; CXR; U&E; loop diuretic for symptom relief (furosemide 40 mg OD) while awaiting echo; BP management; weigh patient (baseline for monitoring); advise daily weights; review medications for HF triggers (NSAIDs, CCBs exacerbating fluid retention)Do not start ACEi without baseline U&E; do not start spironolactone without specialist echo-confirmed LVEF; do not give NSAIDs

7A β€” Address the patient's expectation first
🀝
This patient was brought in by his wife β€” his expectation may be to get "checked out" and leave. Transform that into genuine engagement.
1
Validate

Acknowledge that he has been managing the breathlessness without wanting to make a fuss β€” this is a common and understandable response, not a failure.

"I can see you've been getting on with things despite this β€” and I really appreciate you coming in today. You're right that this has been going on for a while, and we should understand it properly."
2
Explain

Frame the investigation as proactive β€” not just about what's causing the breathlessness, but about giving him the best chance of maintaining his quality of life going forward.

"The breathing test and X-ray aren't just to find out what's wrong β€” they're going to tell us how well your lungs are working right now and what we can do to make sure they don't get worse over time."
3
Negotiate

Give him something concrete he can take away today β€” ideally the smoking cessation referral, the written self-management plan template, and an appointment for spirometry.

"Today I'm going to arrange the breathing test and the X-ray, and I'm also going to put in a referral to our smoking cessation service β€” that's the single most powerful thing we can do for your breathing long-term, regardless of what the tests show."
7B β€” Why treatment matters: goals tailored to this patient
Treatment goals
🚬 Stop smoking β€” most impactful single action 🫁 Slow lung function decline πŸƒ Improve exercise tolerance πŸ₯ Reduce exacerbation rate 😰 Reduce breathlessness at symptom level 🧠 Maintain independence πŸ’‰ Vaccinations β€” influenza + pneumococcal πŸ“‹ Written self-management plan + rescue pack
Motivational framing
"Stopping smoking now β€” even after 30 years β€” can reduce the rate at which your lung function declines by half. Your lungs won't repair themselves fully, but they won't get worse as fast. That translates to significantly more time before breathlessness becomes severely limiting."
"People who go through our pulmonary rehabilitation programme often tell us it's the most effective thing they've ever done for their breathing β€” significantly better than inhalers alone. It's supervised exercise plus education about your condition."
7C β€” Non-medication management: smoking cessation + pulmonary rehab
🚬
Smoking Cessation
Target: complete cessation β€” no safe level of smoking in COPD
Mechanism

Smoking causes ongoing airway inflammation and accelerated loss of lung function in COPD β€” approximately 50 mL/year FEV₁ decline vs 30 mL/year in non-smokers. Cessation halves this decline rate within 12 months of stopping, regardless of how long or how much the patient has smoked.

Practical

Refer to NHS Stop Smoking Service (12-week behavioural support programme). Prescribe varenicline (Champix β€” most effective pharmacotherapy; 4Γ— placebo rate) or NRT (patch + gum or lozenge combination). Set a quit date together; document it; follow up at 2 weeks for support.

Smoking cessation is the ONLY intervention proven to slow FEV₁ decline in COPD
πŸƒ
Pulmonary Rehabilitation
Target: complete 12-session programme (NICE-recommended)
Mechanism

Supervised exercise training reduces dynamic hyperinflation, increases peripheral muscle efficiency, and significantly reduces the perception of breathlessness at any given workload. NICE recommends PR for all COPD patients with MMRC grade 3 or above (breathlessness stops them after 100 metres on flat).

Practical

Refer via respiratory physiotherapy or community pulmonary rehab service. Most programmes run twice weekly for 6 weeks (12 sessions). Effective even in very severe COPD. Patients who complete PR have 39% fewer hospital admissions in the following year.

PR reduces hospital admissions by 39% and improves exercise tolerance by 30–50%
πŸ’‰
Vaccinations
Mandatory in COPD β€” influenza annually, pneumococcal, COVID
Mechanism

Respiratory infections are the most common precipitant of COPD exacerbations β€” influenza and pneumococcal pneumonia can cause life-threatening acute-on-chronic respiratory failure in severe COPD. Each prevented exacerbation preserves lung function and reduces disease progression.

Practical

Influenza vaccine annually (September–November). Pneumococcal vaccine (PPV23) once β€” or twice if first given under 65. COVID booster per current JCVI guidance. RSV vaccine if newly recommended in age group. All these are free on the NHS for COPD patients.

Annual influenza vaccine reduces COPD hospitalisation by 52% (Cochrane review)
πŸ“‹
Self-Management Plan + Rescue Pack
Every COPD patient should have a written action plan and rescue prescription
Mechanism

Written self-management plans empower patients to recognise and respond to early exacerbation symptoms, reducing the delay to treatment that worsens outcomes. Early antibiotic and steroid use at the start of an exacerbation significantly reduces hospitalisation rates.

Practical

Prescribe a rescue pack: prednisolone 30 mg Γ— 5 days + amoxicillin 500 mg TDS Γ— 5 days (or doxycycline 200 mg OD Γ— 5 days). Give written instructions: "Use if breathlessness increases and sputum becomes yellow or green and/or you develop a fever." Advise GP review within 48 hours of starting.

Rescue packs at home reduce COPD hospitalisation by 30% in eligible patients
🍺
Alcohol Reduction
Target: under 14 units/week (currently 20/week)
Mechanism

Alcohol at 20 units per week puts this patient at risk of alcoholic cardiomyopathy (a direct differential for HF-related breathlessness), aspiration pneumonia (worsening COPD), and impaired immune response (increasing exacerbation frequency). Alcohol also reduces engagement with exercise programmes and cessation support.

Practical

AUDIT-C screening; 5–10 minute brief intervention (IBA framework: Ask, Advise, Act); referral to local alcohol service or NHS Drink Free Days app; LFTs to assess hepatic impact. If cardiac cause of breathlessness confirmed β€” abstinence may partially reverse alcoholic cardiomyopathy.

Alcohol abstinence can partially reverse alcoholic cardiomyopathy within 6–12 months
πŸ’¨
Inhaler Technique Review
Target: correct device and technique confirmed at every review
Mechanism

Poor inhaler technique is the most common cause of inadequate COPD and asthma control β€” up to 80% of patients in community audits use poor technique. Switching devices or step-up therapy without addressing technique first leads to unnecessary medication escalation.

Practical

Ask patient to demonstrate their inhaler technique at every review. Use the device-specific technique checklist. Spacer with MDI improves delivery by 30–40% in many patients. Breath-actuated inhalers (e.g. EasyHaler) better for patients with poor hand coordination. Spiriva Respimat preferred over HandiHaler if hand strength is limited.

Correct inhaler technique alone improves COPD control equivalently to one treatment step-up
7F β€” Drug reference cards: COPD and breathlessness
SABA β€” Salbutamol
Ventolin Β· 100 mcg/actuation MDI Β· reliever inhaler
Step 1 COPD/asthma100–200 mcg PRN
βœ“ Prefer when
PRN reliever for all COPD and asthma patients β€” always prescribed alongside controller therapy
Acute breathlessness β€” 2.5–5 mg via nebuliser in exacerbation
Mild asthma as sole therapy if symptoms are infrequent (under 2 per week)
βœ— Caution if
Overuse (over 3 times per week) = inadequate asthma control β†’ step up ICS
Hypokalaemia risk at high doses β€” check electrolytes if nebulised frequently
πŸ’¬ Counselling

"This is your reliever inhaler β€” use it when you feel breathless, not regularly. If you're using it more than 2–3 times a week, let us know β€” that tells us the condition isn't as well-controlled as it should be."

The SCA key point for SABA: overuse (over 3 times per week in asthma) is itself a diagnostic signal of uncontrolled disease. Naming this threshold and committing to step-up if it is exceeded scores in the Tasks domain.

LAMA β€” Tiotropium
Spiriva Respimat 2.5 mcg Β· once-daily long-acting anticholinergic
First-line COPD5 mcg OD (2 puffs)
βœ“ Prefer when
COPD GOLD stage 2 or above β€” once-daily bronchodilator superior to SABA alone for functional outcomes
Reduces exacerbation rate by 14% compared with placebo (UPLIFT trial)
Improves exercise tolerance and health-related quality of life in moderate COPD
βœ— Avoid if
Severe urinary retention (BPH with acute retention) β€” anticholinergic effect worsens retention
Narrow-angle glaucoma β€” avoid spray in eyes; use spacer if MDI
πŸ’¬ Counselling

"This inhaler is taken once a day, every day β€” it's a controller, not a reliever. It keeps the airways open throughout the day. If you get a dry mouth, that's a normal side effect and tends to improve after a few weeks."

LAMA is the standard first-line controller for COPD β€” more effective than LABA or ICS monotherapy as first-line in COPD. Naming tiotropium specifically (rather than a generic "bronchodilator") demonstrates clinical precision and scores in the Tasks domain.

ICS/LABA β€” Combination Inhaler
Fostair (beclometasone/formoterol) Β· Seretide Β· Symbicort β€” for COPD with frequent exacerbations or asthma
Step 2 COPD/asthmaVaries by device
βœ“ Prefer when
COPD with blood eosinophils β‰₯300 cells/Β΅L β€” predicts ICS response and reduces exacerbation risk
COPD with 2+ exacerbations per year despite LAMA monotherapy
Asthma β€” ICS/LABA combination recommended from GINA Step 3 upwards
βœ— Avoid / caution
ICS monotherapy as sole COPD treatment β€” no evidence base; LABA must accompany ICS in COPD
High-dose ICS long-term β†’ increased pneumonia risk in COPD (TORCH trial evidence)
ICS without LABA in asthma β€” sub-optimal; always add LABA at step 3
πŸ’¬ Counselling

"This combination inhaler contains two medicines β€” one that opens the airways and one that reduces the inflammation. Rinse your mouth and gargle with water after each dose to prevent a sore mouth or thrush."

Key SCA point: in COPD, ICS should not be used alone β€” must be combined with LABA. In asthma, ICS is the cornerstone and should be stepped up (not removed) even when symptoms improve. Demonstrating awareness of when ICS is and is not indicated scores in Tasks.

Furosemide (Loop Diuretic)
Frusemol β€” first-line symptom management in heart failure
HF symptoms20–80 mg OD–BD
βœ“ Prefer when
Acute and chronic HF with fluid overload β€” bibasal crackles, ankle oedema, orthopnoea
Rapid symptom relief β€” reduces pulmonary venous pressure within 15–30 minutes of IV dose
First-line in decompensated HF alongside ACEi/beta-blocker titration
βœ— Avoid / caution
Hypovolaemia / dehydration β€” will worsen acute kidney injury
eGFR under 30 β€” reduced efficacy; thiazide-like diuretic may be more effective or combination needed
πŸ”¬ Monitor
U&E and creatinine at 1–2 weeks after starting or dose change
Daily weight at home β€” advise patient to increase dose by 20–40 mg if weight rises over 2 kg in 2 days
πŸ’¬ Counselling

"This water tablet will make you pass more urine β€” most people find the effect comes on within an hour of taking it. Take it in the morning to avoid getting up at night. Weigh yourself every morning before eating: if your weight goes up by more than 2 kg in two days, take an extra tablet and let us know."

Daily weight monitoring β€” 2 kg rise in 2 days = diuretic dose increase β€” is the most examinable self-management instruction for heart failure in the SCA. Stating this specifically demonstrates that the management plan is personalised and actionable.

Varenicline (Champix)
Partial nicotinic acetylcholine receptor agonist β€” most effective single pharmacotherapy for smoking cessation
Cessation 1st line0.5–1 mg BD
βœ“ Prefer when
Motivated to quit β€” most effective pharmacotherapy (4Γ— placebo; superior to NRT)
Previous NRT failure β€” varenicline works through a different mechanism
COPD β€” smoking cessation is the single most impactful disease-modifying intervention
βœ— Caution
Psychiatric history β€” rare neuropsychiatric effects; warn about mood changes; monitor closely
Reduce dose in severe renal impairment (eGFR under 30)
πŸ’¬ Counselling

"You start this tablet a week before your quit date. It reduces the cravings and makes smoking less satisfying. Let me know if you notice any mood changes, unusual thoughts, or feeling more irritable than usual β€” we can adjust if needed. Take it with food to reduce nausea."

Smoking cessation with pharmacotherapy is the most impactful single intervention for COPD β€” the SCA examiner expects this to be offered proactively, not as an afterthought. Naming varenicline specifically and explaining its mechanism (4Γ— placebo vs NRT alone) demonstrates evidence-based prescribing.

Prednisolone (Rescue Course)
30 mg OD Γ— 5 days β€” COPD exacerbation rescue pack
Exacerbation30 mg OD Γ— 5 days
βœ“ Use when
COPD exacerbation with increased breathlessness, exercise limitation, or change in sputum colour
Acute asthma attack β€” 40–50 mg OD Γ— 5–7 days; longer if slow response
βœ— Avoid / caution
Diabetes β€” monitor blood glucose; short courses can cause significant hyperglycaemia
Long-term / repeated courses β†’ osteoporosis; bone protection needed if over 3 courses/year
πŸ’¬ Counselling

"If you notice your breathlessness worsening and your phlegm turning yellow or green, start this course of steroid tablets straight away β€” don't wait for symptoms to be severe. Take them with food and let us know you've started, so we can check on you within 48 hours."

The examinable point for prednisolone rescue packs: the patient must know the specific symptoms that trigger use (increased breathlessness + change in sputum colour OR fever) and must understand that GP review within 48 hours is expected. Vague "use if worse" instruction is insufficient.

7G β€” Psychosocial impact: disability, carer burden, and advance care planning
πŸ«‚
Living with progressive breathlessness β€” practical, psychological, and existential impacts
πŸ˜”
Depression and Anxiety

Depression occurs in 40% of people with COPD β€” higher than in any other chronic disease β€” and is independently associated with worse outcomes, more frequent exacerbations, and reduced pulmonary rehabilitation engagement. Anxiety about breathlessness creates a cycle: fear β†’ avoidance β†’ deconditioning β†’ more breathlessness β†’ more fear.

PHQ-9 and GAD-7 should be completed at every annual COPD review. CBT specifically targeting breathlessness-related catastrophising is effective and evidence-based. NHS Talking Therapies referral for mild-moderate; specialist liaison psychiatry for severe or treatment-resistant depression in COPD.

"How has your mood been with all of this going on? Some people find that dealing with breathlessness has a big impact on how they're feeling in themselves β€” that's really common and we can help with that."
🏠
Independence and Functional Limitation

COPD progressively restricts the activities central to identity β€” gardening, walking the dog, playing with grandchildren, doing DIY. For a retired plumber who was physically active throughout his working life, this loss of physical capacity represents a profound change in identity and self-worth.

Occupational therapy assessment for home adaptations; stair rail, shower seat, energy conservation techniques. Pulmonary rehabilitation specifically addresses functional limitation through both physical reconditioning and psychological approaches to breathlessness management.

"What are the things you can't do now that you really miss being able to do? I'm asking because there are specific support services that can help with exactly those things."
πŸ‘©
Partner and Carer Burden

The patient's wife has been worried enough to insist on this consultation β€” she is already carrying a significant carer burden. Involving her in the management plan (with the patient's consent) improves adherence, reduces carer anxiety, and ensures someone can recognise and respond to an acute exacerbation.

COPD carers often need their own psychological support β€” carer assessment through social services or the local COPD charity (British Lung Foundation / Asthma + Lung UK) can provide this. Annual carer review is a GP contractual requirement.

"Would your wife like to come in next time and hear about what the tests show and what we're planning? She clearly cares a great deal, and it often helps when both of you understand what to look out for."
πŸ“‹
Advance Care Planning in Severe COPD

COPD is a life-limiting illness β€” GOLD stage 3–4 patients have a 5-year mortality comparable to many cancers. Yet advance care planning conversations are significantly delayed in COPD compared to cancer, leaving patients without documented wishes at the point of acute deterioration.

When functionally appropriate (GOLD 3–4), introduce advance care planning sensitively: "Some people with lung conditions like yours want to think ahead about what kind of care they'd want if they became very unwell β€” would that be something you'd feel comfortable discussing?" Document DNACPR status; ReSPECT form; preferred place of care.

"I don't want to get too far ahead of ourselves β€” but at some point, when you feel ready, it might be worth thinking about what would matter most to you if you became very unwell. There's no rush, and we'd do it at your pace."

7J β€” Safety-netting

⚠ Three scenario-specific safety-net phrases

πŸ”΄ Emergency β€” severe breathlessness or acute deterioration
"If you have sudden severe breathlessness β€” worse than usual at rest, or your lips or fingernails go blue β€” call 999 immediately. Don't wait to see if it improves on its own. If you notice any blood in your cough at any point, come and see us urgently the same day."
This phrase specifically covers acute exacerbation of COPD requiring emergency treatment, possible PE, and haemoptysis as a malignancy red flag. The mention of blue lips (cyanosis) gives the patient a visible and concrete danger signal to act on, which is more reliable than asking them to judge subjective breathlessness severity.
πŸ’Š COPD rescue pack β€” when to use it
"Use the rescue pack β€” the steroid tablets and antibiotics β€” if your breathlessness gets significantly worse and your phlegm turns yellow or green. Start them the same day you notice this, and let us know by the next day so we can check how you're doing."
Specific trigger criteria for rescue pack use prevents both overuse (for routine breathlessness) and dangerous underuse (delaying treatment until hospitalisation is needed). The instruction to notify the surgery within 24 hours of starting ensures clinical review is not missed and allows documentation of the exacerbation for the annual exacerbation count.
🟠 Weight monitoring β€” heart failure
"Weigh yourself every morning before breakfast. If your weight goes up by more than 2 kilograms in 2 days β€” even if you don't feel much worse β€” take an extra water tablet and ring us the same day. Early fluid build-up is much easier to treat than a full flare-up."
The 2 kg / 2-day weight gain rule is the most specific and most actionable HF self-monitoring instruction β€” it identifies early decompensation before clinical deterioration requires hospitalisation. Patients who monitor their weight and act on this instruction have 30% fewer HF hospitalisations. This instruction must be given in writing as well as verbally.

Closing the consultation
"To summarise: we're doing a breathing test, chest X-ray, and blood tests today. I'm also putting in a referral to the stop-smoking service, because that's the most important thing we can do for your lungs."
"If you notice any blood in your cough β€” even a small amount β€” come straight in the same day. Don't wait."
"I know it can feel overwhelming to hear that your breathing has been affected by the smoking. But the fact that you're here, and that we know about it now, means we can do a lot."
"Is there anything you'd like to ask, or anything that isn't clear from what we've talked about today?"

Complete the checklist above to see your score interpretation and feedback
"My wife made me come. I've been fine β€” I just get a bit puffed going up the stairs. I've been smoking for 30 years so I suppose I've only got myself to blame."
Who you are

David Hartley, 63, retired plumber. You worked on pipe lagging (including asbestos pipe insulation) before the late 1980s, though you don't immediately mention this unless specifically asked about your work. You've been breathless climbing stairs for about 6 months, always have a cough in the mornings, and get a bit of phlegm β€” usually clear but sometimes yellow in winter. You have never coughed up blood. You drink a 750 mL bottle of wine most evenings plus a few beers at the weekend β€” about 20 units total.

Hidden concern

You are worried it might be lung cancer β€” your father died of it at 65, which is why you haven't wanted to come in. You won't say this unless asked: "Is there something specific you're worried this might be?" β€” at which point you'll say: "My dad died of lung cancer at 65. I've been putting off coming in because I'm not sure I want to know."

Symptoms if asked
  • Stairs: breathless after one flight β€” needs to stop and rest (MMRC grade 2–3)
  • Can lie flat; no ankle swelling noticed
  • Morning cough most days β€” phlegm usually clear
  • Has never coughed up blood β€” confirm this clearly if asked
  • Smoked 25/day for 30 years β€” quit 5 years ago
  • No chest pain; no weight loss noticed (but hasn't weighed himself)
Challenges
  • Resistant to change: "I've already given up smoking β€” what more can I do?" β€” respond if varenicline is offered: "Is there any point now?"
  • On alcohol: minimises unless asked directly β€” AUDIT-C score likely 5–6
  • If 2ww referral is explained: becomes anxious β€” "Does that mean you think I have cancer?"
  • If wife's involvement is offered: softens immediately β€” "She'd appreciate that actually."
"Is this very serious then? I mean, what are we actually looking at here?"

Resolution: David engages if the candidate: (1) directly names and addresses his cancer fear; (2) addresses the smoking history non-judgementally and offers cessation support even now ("quitting helps even after 30 years"); (3) involves his wife sensitively; (4) explains the 2ww referral honestly but without creating certainty about cancer diagnosis; (5) gives him a concrete action today. He is put off by excessive clinical detachment or premature reassurance.

🚫 8 Danger Zones
βœ—
Diagnose COPD without spirometry
β†’ "I think COPD is the most likely cause, but we need the breathing test to confirm it before I can say for certain"
βœ—
Miss haemoptysis trigger for 2ww
β†’ Always ask explicitly: "Have you ever noticed any blood in your phlegm β€” even a streak?" If yes + over 40 + smoker β†’ 2ww
βœ—
Not quantifying smoking in pack-years
β†’ Calculate: (cigarettes/day Γ· 20) Γ— years smoked = pack-years. Over 30 = high risk
βœ—
Miss occupational asbestos history in a plumber
β†’ "What did you work with β€” were you ever exposed to asbestos, dust, or chemical fumes?"
βœ—
Order D-dimer in high Wells PE patient
β†’ Wells over 5 β†’ CTPA directly; D-dimer will be positive non-specifically and adds no value
βœ—
Not checking SpOβ‚‚ in the first 2 minutes
β†’ Pulse oximetry is mandatory and must be the first objective measurement in any breathless patient
βœ—
Smoking cessation not offered
β†’ Offer at every consultation; stopping now (even after 30 years) halves the rate of further FEV₁ decline
βœ—
Rescue pack without specific trigger criteria
β†’ "Use if breathlessness worsens AND sputum turns yellow or green β€” same day, and ring us within 24 hours"
