Name: Sore throat — bulletproof documentation — ER Toolkit
Creator: Kim Trinh, MD

Most sore throats are benign, but a few are airway emergencies wearing the same costume. The first move is always an airway assessment, and the defensible chart records the red flags you looked for — and the antibiotic decision tied to a score, not a hunch.

01What's at stake

The misses are the deep-space and airway infections read as routine pharyngitis, and the patient sent home as "viral" who returns with Lemierre syndrome. Acute pharyngitis lasts only 3–5 days; a longer or worsening course should broaden the differential to abscess, Lemierre, and even malignancy.

02Can't-miss airway / deep-space mimics

Epiglottitis / supraglottitis — drooling, stridor, tripoding, toxic appearance.
Peritonsillar abscess — trismus, uvular deviation, "hot potato" voice.
Retropharyngeal / parapharyngeal abscess — neck pain/stiffness, reduced neck motion, trismus.
Ludwig angina — "woody" induration of the floor of the mouth, drooling (often post-dental).
Lemierre syndrome — septic IJ thrombophlebitis with emboli, just outside the acute window.
Diphtheria — pharyngeal pseudomembrane.

Red flags: drooling, voice change, stridor, trismus, or a toxic appearance signal a dangerous process — assess and protect the airway first.

03Group A strep — score it, don't guess

Modified Centor (McIsaac): fever (+1), absence of cough (+1), tender anterior cervical nodes (+1), tonsillar exudate (+1); age 3–14 (+1), 15–44 (0), >44 (−1).
Don't test or treat patients with clear viral features or a score of 0–1.
Rapid antigen is specific — a positive means treat; a negative in a child warrants a backup throat culture (not needed in adults).
Penicillin/amoxicillin is first-line (resistance never documented); for true severe penicillin allergy use clindamycin/azithromycin — not a cephalosporin.
Steroids and NSAIDs/acetaminophen help symptoms; reserve steroids for severe symptoms in non-diabetic, non-immunosuppressed patients.

Skip the typing

Work the case in the Sore Throat Workup — it records the airway assessment and the Centor/McIsaac criteria, and assembles an MDM that documents the airway-threatening mimics were excluded and the antibiotic decision was score-based.

04What to document

▼ weak

"Sore throat, gave amoxicillin. Discharged."

▲ defensible

"Sore throat x2 days; no drooling, voice change, stridor, trismus, neck stiffness, or toxic appearance — airway-threatening causes (epiglottitis, deep-space abscess, Ludwig) considered and excluded. Submental space soft, no induration; symmetric oropharynx. Centor/McIsaac documented; rapid strep positive → penicillin (allergy interview: none). Tolerating PO. Return precautions for difficulty breathing/swallowing, drooling, voice change, neck swelling, or symptoms beyond 3–5 days; patient verbalized understanding."

05Where charts fail

Not documenting the airway/red-flag assessment (a reported voice change needs visualization even if it "sounds fine").
Not palpating under the tongue for Ludwig angina.
Prescribing antibiotics for clearly viral symptoms or a Centor 0–1.
Substituting a cephalosporin without asking the nature of the penicillin allergy.
No return precautions / follow-up — the safety net for Lemierre and missed abscess; and broaden the differential beyond 3–5 days.
