Clinical Skills
Building on the foundation of rapport and presenting complaints, Part 2 explores the crucial background information that reveals risk factors, genetic predispositions, and environmental contexts; the essential "why" behind clinical presentations.
💊 Step 4: Drug History - Beyond Prescriptions
Comprehensive Medication Review
Essential Inclusions:
🎯 Complete Medication Profile
- Prescribed medications
- Over-the-counter drugs
- Herbal remedies and supplements
- Vitamins and alternative therapies
🎯 Critical Safety Question
- "Do you have any medication allergies?"
- Document both drug and specific reaction
- Example: "Penicillin - causes rash"
Patient Safety Alert: Ignoring documented allergies can have fatal consequences. Always verify and document allergic reactions thoroughly.
🏥 Step 5: Past Medical History (PMH)
The Patient's Health Resume
Memory Jogging Questions:
🎯 Hospitalization History
- "Have you ever been admitted to hospital?"
- "What was the reason for admission?"
🎯 Surgical History
- "Have you ever had any surgeries?"
- Document procedure types and dates when possible
🎯 Chronic Conditions
- "Do you have ongoing conditions like:"
- Hypertension, Diabetes, Asthma
- Thyroid disorders, Arthritis, etc.
👨👩👧👦 Step 6: Family History (FH)
The Genetic Blueprint
Key Conditions to Explore:
- Tuberculosis (TB)
- Diabetes Mellitus
- Hypertension
- Heart Disease
- Cancer (various types)
- Arthritis, Gout, Epilepsy
- Mental Illness
Going Deeper:
🎯 Age at Onset
- Don't just document "heart disease"
- Ask: "How old was your relative when diagnosed?"
- Early onset suggests stronger genetic risk
🌍 Step 7: Social History (SH)
Understanding the Patient's World
Essential Social Domains:
🎯 Occupation
- "What do you do for work?"
- Examples: Asbestos exposure → lung disease
- Farming → parasitic infections
🎯 Home Environment
- "Who lives with you?"
- Living conditions and housing quality
- Crowding indicators
🎯 Habits & Substances
- Smoking (calculate pack-years)
- Alcohol consumption (quantity/frequency)
- Approach: Use non-judgmental questioning
🎯 Travel History
- "Have you traveled recently or in the past?"
- Critical for: Tropical diseases, region-specific illnesses
- Examples: Malaria, Schistosomiasis
🧠 Step 8: Psychological Assessment & Third-Party History
Beyond the Physical Symptoms
Behavioral Observation:
🎯 Reading the Room
- Patient's mood and affect
- Personality presentation
- Storytelling style and emotional tone
- Anxiety, depression, or denial indicators
🎯 When to Suspect Psychological Factors
- Physical exam reveals minimal objective findings
- Symptoms disproportionate to clinical signs
- Multiple system complaints without clear pattern
Third-Party History Situations:
- Unconscious or sedated patients
- Young children
- Cognitive impairment or dementia
- Acute confusion or delirium
- Language barriers
🔗 Putting It All Together: Clinical Synthesis
From Data to Diagnosis
Synthesis Framework:
🎯 Step 1: Assess Reliability
- Evaluate patient as historian
- Determine information credibility
🎯 Step 2: Identify System
- Based on symptom pattern
- Determine primary system involved
- Examples: Respiratory, Cardiovascular, GI
🎯 Step 3: Differential Diagnosis
- List potential conditions
- Rank from most to least likely
- Creates logical starting point for exam

Clinical Reasoning in Action
Presenting Complaints:
- Haemoptysis (coughing up blood)
- Chest pain
- Chronic cough
- Weight loss
- System: Strong respiratory indication
Key History Findings:
🎯 HPI Details
- Blood frightened patient
- Sharp pain worse with breathing/coughing (pleuritic)
- Chronic cough with sputum production
🎯 Family History
- Red Flag: Uncle and sister with TB
- Strong infectious disease clue
🎯 Social History
- Smoker (lung cancer/TB risk)
- Crowded living conditions (TB spread risk)
- Moderate alcohol use
Clinical Synthesis:
- Primary Suspect: Pulmonary Tuberculosis
- Supporting: Chronic cough, weight loss, haemoptysis, strong TB contact history
- Alternatives: Pneumonia, Lung Cancer (smoking history)
- Exam Focus: Lung auscultation, TB-specific signs
🎯 Final Clinical Takeaways
Mastering the Art of History Taking
Essential Principles:
🎯 Observe While Listening
- Facial expressions and gestures
- Body language and eye contact
- Emotional cues and nonverbal communication
🎯 History as Hypothesis
- History creates clinical hypothesis
- Physical examination tests the hypothesis
- Diagnostic testing provides confirmation
🎯 Practice Development
- Skill improves with each patient encounter
- Pattern recognition develops over time
- Both art and science components
Clinical Wisdom: You now possess a comprehensive framework for powerful patient history taking. The art develops through consistent practice and reflective clinical experience.
