Sample SOAP Note for Streptococcal Pharyngitis in a 12-Year-Old
SUBJECTIVE
Chief Complaint: Sore throat and fever
History of Present Illness:
- 12-year-old previously healthy patient presents with acute onset of sore throat for 2 days
- Associated symptoms: fever (reported 102°F at home), pain with swallowing, headache
- May report abdominal pain, nausea (common in children) 1
- Absence of viral symptoms: No cough, rhinorrhea, hoarseness, or oral ulcers 2
- Possible exposure to known strep case at school
- No difficulty breathing or drooling
Past Medical History: None
Medications: None
Allergies: NKDA
Immunizations: Up to date
OBJECTIVE
Vital Signs:
- Temperature: 102.5°F (39.2°C)
- Heart Rate: 98 bpm
- Blood Pressure: 110/70 mmHg
- Respiratory Rate: 18/min
- SpO2: 99% on room air
Physical Examination:
General: Alert, appears mildly uncomfortable but not toxic
HEENT:
- Pharynx: Marked tonsillopharyngeal erythema with bilateral tonsillar exudates
- Soft palate petechiae present
- Uvula: Erythematous and edematous ("beefy red swollen uvula") 1
- No oral ulcers, no rhinorrhea
Neck: Tender bilateral anterior cervical lymphadenopathy (1.5 cm nodes)
Lungs: Clear to auscultation bilaterally, no cough
Skin: No scarlatiniform rash noted
Diagnostic Testing:
- Rapid Antigen Detection Test (RADT): Positive for Group A Streptococcus
- Note: Positive RADT does not require backup throat culture due to high specificity 2
ASSESSMENT
Acute Group A Streptococcal Pharyngitis
Clinical reasoning: This 12-year-old falls within the peak age range (5-15 years) for GAS pharyngitis 1. The presentation includes classic features: sudden onset sore throat, fever 101-104°F, tonsillar exudates, anterior cervical lymphadenopathy, and absence of viral symptoms (no cough, rhinorrhea, or hoarseness). Positive RADT confirms diagnosis and no backup culture is needed 2.
PLAN
Antibiotic Therapy
First-line treatment: Amoxicillin 50 mg/kg once daily (maximum 1000 mg) for 10 days 2
For this 40 kg patient: Amoxicillin 500 mg PO twice daily for 10 days
Alternative first-line option: Penicillin V 250 mg PO three times daily for 10 days 2
Rationale: Penicillin and amoxicillin are first-line agents based on narrow spectrum, low adverse effects, modest cost, and strong evidence for preventing acute rheumatic fever and suppurative complications 2. The 10-day duration is essential to eradicate GAS from the pharynx 2.
Symptomatic Management
- Ibuprofen 400 mg PO every 6 hours as needed for pain and fever (strong evidence over acetaminophen) 2
- Avoid aspirin (risk of Reye syndrome in children) 2
- Do not prescribe corticosteroids (weak evidence, not recommended routinely) 2
- Encourage adequate hydration and rest
Patient/Parent Education
- Contagiousness: Patient can return to school 24 hours after starting antibiotics 2
- Complete full 10-day antibiotic course even if symptoms improve
- Expected improvement within 24-48 hours of starting antibiotics
- Red flags for return: Worsening symptoms after starting antibiotics, difficulty breathing, drooling, inability to swallow, or symptoms persisting beyond 5 days of treatment 3
Follow-Up
- No routine follow-up testing needed (post-treatment cultures not recommended) 2
- Return if symptoms worsen or persist beyond 5 days of treatment
- Do not test or treat asymptomatic household contacts 2
Important Caveats
If penicillin allergy were present:
- Non-anaphylactic allergy: Cephalexin 20 mg/kg/dose twice daily for 10 days 2
- Anaphylactic allergy: Clindamycin 7 mg/kg three times daily for 10 days OR azithromycin 12 mg/kg once daily for 5 days 2
- Note: Macrolide resistance varies geographically; consider local resistance patterns 2
This approach prevents acute rheumatic fever, suppurative complications (peritonsillar abscess, cervical lymphadenitis), shortens symptom duration, and reduces transmission 2.
