What focused pediatric assessment (interview, OPQRST, review of systems, physical exam, and assessment and plan) is recommended for a 3‑year‑old female presenting with cough and sore throat?

Focused Assessment for 3-Year-Old with Cough and Sore Throat

For a 3-year-old with cough and sore throat, your assessment must distinguish between specific and non-specific cough patterns, as this fundamentally determines your diagnostic and management pathway 1.

Interview Questions (History)

Critical Initial Characterization

• Cough quality: Is it wet/productive or dry? This is the single most important distinguishing feature in pediatric cough 1

  • Wet cough suggests protracted bacterial bronchitis, aspiration, or bronchiectasis
  • Dry cough suggests viral illness, asthma, or upper airway disorders

• Duration: How long has the cough been present?

  • <3 weeks = acute (likely viral)

  • 4 weeks = chronic (requires systematic evaluation per CHEST guidelines) 1

Specific Cough Pointers to Identify

Ask about these red flags that indicate serious underlying pathology 1:

• Hemoptysis (any blood in sputum)
• Failure to thrive or poor weight gain
• Dyspnea or difficulty breathing at rest
• Feeding difficulties or choking with feeds
• Recurrent pneumonias
• Digital clubbing noticed by parents
• Chest pain
• Cardiac symptoms (exercise intolerance, syncope)

Age-Specific Considerations for 3-Year-Old

Note: GAS pharyngitis in children <3 years typically presents with mucopurulent rhinitis, excoriated nares, and diffuse adenopathy—NOT exudative pharyngitis 2. The prevalence of strep throat is very low in this age group, and acute rheumatic fever is exceedingly rare 2.

Environmental and Social History

• Tobacco smoke exposure (critical exacerbating factor) 1
• Other pollutant exposures
• Daycare attendance
• Recent sick contacts
• Foreign body aspiration risk: Any witnessed choking episode? Sudden onset cough? 1

Associated Symptoms

• Fever pattern and duration
• Rhinorrhea (clear vs. purulent)
• Difficulty swallowing
• Voice changes
• Ear pain
• Rash
• Vomiting or feeding intolerance

Past Medical History

• Prenatal and birth history 3
• Developmental milestones 3
• Immunization status 3
• Previous respiratory infections or hospitalizations
• Known allergies or asthma

OPQRST Framework (Adapted for Pediatrics)

O - Onset:

• Sudden (foreign body, acute infection) vs. gradual?
• Any triggering event?

P - Provocation/Palliation:

• What makes cough worse? (lying down, activity, cold air, laughing)
• What makes it better? (sitting up, warm liquids)
• Does anything relieve the sore throat?

Q - Quality:

• Cough character: Barky (croup), whooping (pertussis), staccato (chlamydia), wet/productive vs. dry 1
• Throat pain: Sharp, scratchy, difficulty swallowing?

R - Region/Radiation:

• Where does throat hurt most?
• Any ear pain (referred pain common)?

S - Severity:

• Impact on activity and sleep (more useful than pain scales in 3-year-olds)
• Parental assessment of child's distress 1

T - Timing:

• Worse at night? (asthma, GERD)
• Morning vs. evening pattern?
• Constant vs. intermittent?

Review of Systems (Pertinent Positives/Negatives)

Respiratory

• Wheezing, stridor, or noisy breathing
• Shortness of breath
• Chest retractions

ENT

• Nasal congestion/discharge
• Snoring or sleep-disordered breathing
• Ear discharge

GI

• Vomiting, regurgitation (GERD consideration) 1
• Diarrhea
• Abdominal pain

Constitutional

• Fever, chills
• Fatigue, irritability
• Appetite and fluid intake (assess hydration)
• Weight loss or poor growth 1

Skin

• Rash (viral exanthem, scarlet fever)

Physical Examination

General Appearance

• Overall wellness vs. toxicity (most important assessment) 3
• Hydration status
• Work of breathing
• Ability to speak/cry normally

Vital Signs

• Temperature (tympanic acceptable >1 year) 4
• Respiratory rate (normal 20-30 for 3-year-old)
• Heart rate
• Oxygen saturation (pulse oximetry essential) 5

HEENT

• Oropharynx:
  • Tonsillar size and exudates (though exudates rare in this age for strep) 2
  • Pharyngeal erythema
  • Palatal petechiae
• Nasal examination: Excoriated nares, mucopurulent discharge 2
• Ears: Tympanic membranes (referred pain from otitis)
• Lymph nodes: Cervical adenopathy (size, tenderness, mobility) 2

Respiratory

• Inspection: Retractions, nasal flaring, accessory muscle use
• Auscultation:
  • Wheezing (asthma)
  • Crackles (pneumonia, bronchitis)
  • Stridor (upper airway obstruction)
  • Decreased breath sounds (consolidation, effusion)
• Percussion: Dullness suggests consolidation

Cardiovascular

• Heart sounds, murmurs (if cardiac etiology suspected)

Skin

• Rash patterns
• Digital clubbing (chronic lung disease) 1

Growth Parameters

• Plot weight, height on growth chart 3
• Failure to thrive is a specific cough pointer 1

Assessment and Plan

If NON-SPECIFIC COUGH (Dry, No Red Flags)

Most likely diagnosis: Post-viral cough or acute bronchitis 1

Plan:

• Watch, wait, and review in 2-4 weeks 1
• Supportive care only
• Counsel parents on expected course (usually self-limited)
• Evaluate and eliminate tobacco smoke exposure 1
• No antibiotics, no cough suppressants
• Return precautions: Fever >3 days, worsening symptoms, breathing difficulty

If SPECIFIC COUGH (Wet/Productive OR Red Flags Present)

For wet cough: Consider protracted bacterial bronchitis

• Trial of antibiotics for 2 weeks (amoxicillin-clavulanate typical choice) 1
• Reassess in 2 weeks
• If persistent after 4 weeks of antibiotics total, refer to pediatric pulmonology 1

For sore throat with concern for bacterial infection:

• At age 3, GAS pharyngitis is uncommon 2
• If clinical suspicion high (fever, adenopathy, no viral symptoms), consider rapid strep test
• Most will be viral—supportive care

If any specific cough pointers present 1:

• Chest X-ray indicated (Grade 1B recommendation)
• Spirometry not reliable at age 3 (typically >6 years) 1
• Consider early pediatric pulmonology referral
• Investigate based on specific findings:
  • Foreign body: Bronchoscopy
  • Failure to thrive: Sweat test, immune workup
  • Recurrent infections: Immune evaluation

Red Flags Requiring Immediate Action

• Respiratory distress (retractions, hypoxia)
• Toxic appearance
• Stridor at rest
• Drooling with inability to swallow (epiglottitis concern)
• Suspected foreign body

Common Pitfalls to Avoid

• Don't assume strep throat in 3-year-olds—it's uncommon and presents atypically 2
• Don't ignore wet cough quality—this is the key distinguishing feature in pediatric cough 1
• Don't prescribe antibiotics for non-specific dry cough—most resolve spontaneously 1
• Don't forget environmental tobacco smoke assessment—critical modifiable factor 1
• Don't order spirometry at age 3—unreliable until age 6+ 1
