clinical history taking cough dyspnea fever sputum assessment authoritative
In an MD practical case presentation, describe each symptom systematically: onset, duration, progression, character, associated features, aggravating/relieving factors, severity, and relevant negatives.
Opening statement
“Mr./Ms. X, aged __ years, presented with cough for __ days/months, associated with expectoration, fever, and breathlessness for __ duration.”
Then describe each symptom separately.
1. Cough
Ask and present:
- Onset and duration: Acute, subacute, or chronic? Sudden or gradual onset?
- Character: Dry/non-productive or productive?
- Timing: Worse at night, early morning, on lying down, or with exertion?
- Severity: Frequency, bouts, sleep disturbance, vomiting, syncope, urinary leakage.
- Triggers/relief: Cold air, dust, smoke, exercise, posture, food, medications.
- Associated symptoms: Wheeze, chest pain, fever, sputum, hemoptysis, dyspnea, sore throat, nasal symptoms.
- Important negatives: No hemoptysis, no choking episode, no foreign-body aspiration, no history suggestive of GERD if relevant.
Example presentation
“The patient has had a cough for 10 days. It was gradual in onset and initially dry, becoming productive after 3 days. The cough is more severe in the early morning and is not related to posture. There is no paroxysmal cough, post-tussive vomiting, wheeze, chest pain, or hemoptysis.”
Clinical pointers
| Type of cough | Possible implication |
|---|---|
| Acute | Viral infection, pneumonia, acute bronchitis, aspiration |
| Chronic | Tuberculosis, COPD, asthma, bronchiectasis, malignancy, GERD |
| Nocturnal | Asthma, heart failure, postnasal drip, reflux |
| Paroxysmal | Pertussis, asthma, foreign body |
| Barking | Upper-airway pathology |
| Cough on swallowing | Aspiration, tracheoesophageal communication |
2. Sputum / Expectoration
Avoid saying only “sputum is present.” Describe amount, color, consistency, odor, timing, and blood.
Ask and present:
- Since when is sputum present?
- Approximate amount per day: scanty, moderate, copious. If possible, estimate in mL.
- Color: mucoid, white, clear, yellow, green, rusty, pink/frothy, black.
- Consistency: thin, thick, tenacious, purulent.
- Odor: foul-smelling or not.
- Any layering on standing?
- Any blood: streaky, frank hemoptysis, clots?
- More in morning or after change of posture?
Example presentation
“He has expectoration for 7 days, approximately half a cup per day, yellowish-green, thick and non-foul-smelling. It is predominantly in the morning. There is no hemoptysis.”
Useful interpretation
| Sputum feature | Suggestive conditions |
|---|---|
| Mucoid/white | Viral illness, asthma, chronic bronchitis |
| Yellow/green purulent | Bacterial lower respiratory infection, bronchiectasis exacerbation |
| Rusty | Classically pneumococcal pneumonia |
| Foul-smelling | Anaerobic infection, lung abscess, bronchiectasis |
| Copious, purulent, positional | Bronchiectasis, lung abscess |
| Pink frothy | Acute pulmonary edema |
| Blood-streaked | Infection, bronchiectasis, tuberculosis, malignancy |
Do not diagnose infection solely from sputum color. Correlate with fever, examination, imaging, and microbiology.
3. Fever
Describe the pattern and search for features of infection or systemic disease.
Ask and present:
- Onset and duration
- Maximum documented temperature
- Continuous, intermittent, remittent, relapsing, or evening rise
- Chills, rigor, sweating
- Response to antipyretics
- Associated symptoms: cough, sore throat, dysuria, abdominal pain, rash, headache, altered sensorium, weight loss
- Contact history, travel, tuberculosis exposure, recent hospitalization, immunosuppression
Example presentation
“The patient developed fever 8 days ago. It was acute in onset, high grade, intermittent, associated with chills and sweating, and partially relieved by paracetamol. There is no rash, urinary symptom, altered sensorium, or joint pain.”
Relevant patterns in respiratory cases
| Fever pattern/association | Diagnostic relevance |
|---|---|
| Acute fever with productive cough and pleuritic chest pain | Pneumonia |
| Fever with chronic cough, weight loss, evening rise/night sweats | Tuberculosis or malignancy with secondary infection |
| High fever with rigors | Bacteremia or severe bacterial infection |
| Fever with foul sputum | Lung abscess/anaerobic infection |
| Fever with dyspnea and hypoxemia | Severe pneumonia, pulmonary edema with infection, ARDS, pulmonary embolism with infarction |
4. Dyspnea / Breathlessness
Use the term dyspnea in presentation, but clarify the patient’s description in their own words.
Ask and present:
- Onset: sudden or gradual?
- Duration and progression: stable, progressive, episodic, or worsening?
- At rest or only on exertion?
- Exercise tolerance: walking distance, stair climbing, activities of daily living.
- Severity: use mMRC grade.
- Orthopnea: number of pillows, inability to lie flat.
- Paroxysmal nocturnal dyspnea.
- Wheeze, chest tightness, cough, sputum, chest pain, palpitations, syncope.
- Cyanosis, pedal edema, reduced urine output.
- Sudden onset with pleuritic pain/hemoptysis: consider pulmonary embolism or pneumothorax.
mMRC dyspnea grading
| Grade | Description |
|---|---|
| 0 | Breathless only with strenuous exercise |
| 1 | Short of breath when hurrying or walking up a slight hill |
| 2 | Walks slower than people of the same age or stops when walking at own pace |
| 3 | Stops for breath after about 100 m or a few minutes on level ground |
| 4 | Too breathless to leave home or breathless while dressing |
Example presentation
“He has breathlessness for 5 days, gradual in onset and progressive. Initially it occurred on moderate exertion but is now present on minimal exertion. It corresponds to mMRC grade 3. There is no orthopnea, paroxysmal nocturnal dyspnea, wheeze, chest pain, palpitations, or pedal edema.”
Integrated respiratory case presentation example
“Mr. X, a 56-year-old male, presented with cough for 10 days, expectoration for 7 days, fever for 8 days, and breathlessness for 5 days.
The cough was gradual in onset, initially dry and later productive, predominantly worse in the morning, with no hemoptysis or post-tussive vomiting. Expectoration is approximately 50 mL per day, yellowish-green, thick, and non-foul-smelling.
Fever was acute in onset, high grade and intermittent, associated with chills and sweating, and partially relieved by paracetamol.
Breathlessness was gradual in onset and progressive, initially on exertion and now on walking a short distance on level ground, corresponding to mMRC grade 3. There is no orthopnea, paroxysmal nocturnal dyspnea, chest pain, wheeze, palpitations, or pedal edema.”
High-yield viva points
- Cough + fever + purulent sputum + dyspnea suggests a lower respiratory tract infection, especially pneumonia, but diagnosis requires examination and investigations.
- Chronic cough + weight loss + evening fever/night sweats ± hemoptysis should prompt evaluation for tuberculosis and malignancy.
- Copious, foul-smelling, positional sputum suggests bronchiectasis or lung abscess.
- Sudden dyspnea needs urgent evaluation for pneumothorax, pulmonary embolism, acute pulmonary edema, severe asthma, or acute airway obstruction.
- Always ask for hemoptysis, chest pain, wheeze, weight loss, anorexia, night sweats, smoking history, tuberculosis contact, occupational exposure, and drug history.
