Pediatric history-taking is a systematic, age-appropriate process requiring both direct observation and careful interviewing of both the patient and caregivers. The approach must be modified based on:

• Developmental stage and cognitive ability of the child
• Acuity of presentation (emergency vs. routine care)
• Cultural and socioeconomic context of the family
• Presence of any communication barriers or special needs

Key principles include:

• Establishing rapport with both child and caregiver
• Using age-appropriate language and assessment techniques
• Maintaining a trauma-informed approach
• Documentation of multiple sources of history (caregivers, previous records, other healthcare providers)

Document the primary concern using direct quotations when possible. Essential elements include:

• Primary symptom or concern in patient/caregiver's own words
• Duration of symptoms with precise onset timing
• Context of presentation (routine visit, acute illness, chronic condition follow-up)
• Impact on daily activities and quality of life
• Caregiver's level of concern and understanding

Red flags requiring immediate attention:

• Altered mental status or behavioral changes
• Respiratory distress or cyanosis
• Severe pain or acute onset of symptoms
• Signs of abuse or neglect
• Failure to thrive or sudden weight changes

Construct a detailed chronological narrative using the OLDCARTS framework:

• Onset: Precise timing and nature of initial symptoms
• Location: Specific anatomic location and radiation patterns
• Duration: Timeline of symptoms with specific patterns
• Characteristics: Detailed description of symptoms
• Aggravating factors: What worsens the condition
• Relieving factors: What improves the condition
• Temporal patterns: Diurnal variations, relationship to activities
• Severity: Using age-appropriate pain scales or symptom assessment tools

Additional critical elements:

• Recent exposures and sick contacts
• Changes in routine or environment
• Impact on sleep, feeding, and daily activities
