CTEVT PCL Second Year Health Science | Syllabus Based
Introduction to Clinical Methods
Clinical methods form the foundation of medical practice. This unit covers the systematic approach to patient assessment, which includes history taking and physical examination. Mastering these skills is essential for accurate diagnosis and effective patient management in healthcare settings.
1. History Taking
Definition
History taking is the systematic process of gathering relevant information from a patient, their family, or medical records to understand the patient’s health status, symptoms, and concerns. It is the first and most important step in clinical assessment.
Purpose
- To establish a doctor-patient relationship
- To identify the patient’s chief complaint and present illness
- To obtain information about past medical history
- To assess patient’s family and social history
- To guide physical examination and diagnostic tests
- To formulate a preliminary diagnosis
Components of History Taking
Important: Follow this sequence systematically for comprehensive history taking.
| Component | Description |
|---|---|
| 1. Identification Data | Patient’s name, age, sex, address, occupation, marital status |
| 2. Chief Complaint(s) | Main reason for seeking medical help, recorded in patient’s own words |
| 3. History of Present Illness | Detailed account of symptoms: onset, duration, progression, associated factors |
| 4. Past Medical History | Previous illnesses, surgeries, hospitalizations, allergies, medications |
| 5. Family History | Health status of family members, hereditary diseases |
| 6. Personal and Social History | Lifestyle, habits, diet, occupation, living conditions |
| 7. Review of Systems | Systematic inquiry about symptoms related to each body system |
Clinical Tip:
Use OLDCART mnemonic for History of Present Illness: Onset, Location, Duration, Character, Aggravating factors, Relieving factors, Treatment tried.
2. Physical Examination
General Physical Examination: PILCCOD
PILCCOD Mnemonic
| Pallor | Paleness of skin, conjunctiva, mucous membranes; indicates anemia |
| Icterus | Yellow discoloration of sclera and skin; indicates jaundice |
| Lymph Nodes | Examine cervical, axillary, inguinal nodes for size, tenderness, mobility |
| Cyanosis | Bluish discoloration of lips, tongue, extremities; indicates hypoxia |
| Clubbing | Loss of nail bed angle, bulbous fingertips; seen in chronic respiratory/cardiac diseases |
| Oedema | Swelling due to fluid accumulation; check for pitting (press for 5 seconds) |
| Dehydration | Dry mucous membranes, decreased skin turgor, sunken eyes |
Systemic Examination
Examination Sequence: Inspection → Palpation → Percussion → Auscultation (IPPA method)
Respiratory System
- Inspection: Shape of chest, symmetry, respiratory rate
- Palpation: Tracheal position, chest expansion, tactile fremitus
- Percussion: Note resonance (normal: resonant)
- Auscultation: Breath sounds (vesicular, bronchial), added sounds
Cardiovascular System
- Inspection: Precordial bulge, visible pulsations
- Palpation: Apex beat, thrills, parasternal heave
- Auscultation: Heart sounds (S1, S2), murmurs
- Others: Blood pressure, peripheral pulses, JVP
Gastrointestinal System
- Inspection: Abdominal contour, scars, visible peristalsis
- Palpation: Tenderness, organomegaly, masses
- Percussion: Shifting dullness, organ borders
- Auscultation: Bowel sounds, bruits
Central Nervous System
- Higher functions: Consciousness, orientation
- Cranial nerves: 12 pairs assessment
- Motor system: Tone, power, coordination
- Sensory system: Pain, touch, temperature, vibration
Genitourinary System
- Inspection: Loin swelling, external genitalia
- Palpation: Kidney tenderness, bladder distension
- Percussion: Suprapubic dullness
- Others: Urine output, characteristics, prostate exam (if indicated)
Clinical Examination Flowchart
Clinical examination tools: stethoscope, notebook for documentation
Summary & Key Points
History Taking
7 components: Identification → Chief complaint → HPI → PMH → Family history → Social history → ROS
PILCCOD
General exam mnemonic: Pallor, Icterus, Lymph nodes, Cyanosis, Clubbing, Oedema, Dehydration
Systemic Exam
5 systems: Respiratory, Cardiovascular, Gastrointestinal, CNS, Genitourinary
IPPA Method
Examination sequence: Inspection → Palpation → Percussion → Auscultation
Exam Focus Areas
- Remember the exact sequence of history taking components
- Know PILCCOD components and what each indicates
- Be able to describe examination findings for each system
- Practice differentiating normal vs abnormal findings
