• Timing
• Severity

B. History of Present Illness (HPI)

• Delve deeper into the context:
• Recent illnesses or exposures
• Changes in symptoms
• Impact on daily activities

C. Past Medical History (PMH)

• Chronic illnesses (e.g., hypertension, diabetes)
• Surgeries and hospitalizations
• Allergies
• Medications (including over-the-counter and supplements)

D. Family History (FH)

• Hereditary conditions
• Notable illnesses in immediate relatives

E. Social History (SH)

• Lifestyle factors: smoking, alcohol, drug use
• Occupational exposures
• Living conditions
• Support systems
• Sexual history (as relevant)

F. Review of Systems (ROS)

• Systematic review to identify other symptoms not initially volunteered
• Use relevant checklists based on presenting complaints

Applying Evidence-Based Strategies in History-Taking

Prioritize High-Yield Questions

Research indicates that certain questions have high diagnostic value for specific conditions:

• For chest pain: inquire about radiation, exertion, and associated symptoms like shortness of breath.
