History Taking — Complete Clinical Guide

History Taking — Complete Clinical Guide

1. Introduction

• History taking is one of the most important clinical skills in medicine.

• It helps you reach 80% of the diagnosis, while physical exam and investigations confirm the remaining 20%.

• By your third year of clinical rotations, you must master this skill through practice and repetition.

• A proper history is an art and a science that requires observation, communication, and professionalism.

2. Before Starting History Taking

1. Dress Properly

   • Always wear a clean white apron/coat and carry a stethoscope.

   • Professional appearance creates the right impression on the patient and examiner.

2. Approach from the Right Side

   • Always approach the patient from their right side for examination and interaction.

3. Observe Before You Speak

   • Before asking questions, observe the patient from head to toe.

   • Note general condition, posture, breathing pattern, speech, or visible distress.

3. Introduction Phase

1. Introduce Yourself

   • “Good morning, I am Ronnie,  your clinician working with the medical team.”

   • Explain your purpose: “I would like to ask you a few questions about your illness.”

2. Obtain Consent

   • Always seek verbal consent before beginning the interview.

   • In exams, explicitly say: “With your permission, may I ask you a few questions?”

3. Patient Identification / Demographic Profile

   • Name (and Father’s or Husband’s name)

   • Age

   • Sex / Gender

   • Marital status

   • Religion

   • Residence (to assess environment/sanitation)

   • Occupation (some diseases are occupation-related)

   • Date of admission

   • Mode of admission (ER, emergency, referral)

   • Comorbidities (e.g., diabetes, hypertension, asthma)

4. Presenting Complaint (PC) / Chief Complaint (CC)

• The presenting complaint is the main reason the patient came to the hospital.

• Ask: “What problem brought you here today?”

• If there are multiple complaints, list them in chronological order:

  • Example: Fever for 15 days → Vomiting for 7 days

Characteristics of a Good Presenting Complaint:

1. States the main problem that brought the patient to hospital.

2. Uses patient’s own words, not medical jargon.

   • Example: write “shortness of breath,” not “dyspnea.”

3. Should be an objective statement, not vague.

4. If multiple complaints exist, list in chronological order.

5. Include duration of each symptom.

6. Avoid adding your own interpretation.

5. History of Presenting Complaint (HPC)

• Elaborate each presenting complaint in detail.

• For each symptom, explore:

  1. Onset – sudden or gradual

  2. Duration – since how long

  3. Progress – increasing, decreasing, or intermittent

  4. Site – exact location (especially for pain)

  5. Character – burning, throbbing, stabbing, dull, etc.

  6. Radiation – does pain move anywhere else?

  7. Relieving or aggravating factors – food, posture, medicine

  8. Associated symptoms – nausea, vomiting, fever, etc.

  9. Severity – mild, moderate, severe (affects sleep?)

6. Example: Pain History

• Site: where is the pain? (e.g., epigastric, right lower abdomen)

• Onset: sudden or gradual

• Duration: how long

• Character: dull, sharp, burning, colicky

• Radiation: does it spread to shoulder/back?

• Aggravating/Relieving factors: eating, movement, rest

• Severity: rate 1–10 or mild/moderate/severe

• Associated symptoms: nausea, vomiting, fever, urinary issues

7. Example: Vomiting History

• Frequency: how many times per day

• Duration: since when

• Character: projectile or non-projectile

• Contents: food, bile, blood, mucus

• Timing: before or after meals

• Associated symptoms: nausea, dizziness, abdominal pain

• Relieving factors: rest, medications

8. Systemic Inquiry (System Review)

Ask briefly about symptoms related to all body systems, even if not mentioned by the patient.

9. Past Medical and Surgical History

• Any previous hospitalizations or chronic diseases?

• Past surgeries and any complications?

• Past similar episodes of current complaint?

10. Drug and Allergy History

• Is the patient currently taking any medications?

• Any known drug allergies?

• Any long-term treatments (e.g., insulin, antihypertensives)?
