This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Using Antibiotics Wisely in primary care. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Assess airway, hydration and complications first, then distinguish likely viral illness from group A streptococcal pharyngitis.
  • Use the validated Canadian testing pathway; do not prescribe antibiotics for viral features or an unconfirmed low-probability illness.
  • Escalate stridor, drooling, neck swelling, trismus, toxic appearance or suspected deep-neck infection.
  • A cough, coryza, oral ulcers or hoarseness supports a viral cause and reduces the value of streptococcal testing.

Practical assessment and management workflow

1
Assess airway, drooling, hydration, neck movement, voice and rash before routine throat examination.
2
Apply the Canadian age-appropriate clinical score and test only when the result changes treatment.
3
Provide analgesia and hydration advice and treat confirmed group A streptococcal infection appropriately.
4
Reassess worsening pain, persistent fever or failure to swallow for a suppurative complication.

Safety, red flags and urgent escalation

  • Stridor, tripod positioning, drooling or respiratory distress requires emergency airway support.
  • Trismus, unilateral swelling or a muffled voice suggests peritonsillar or deep-neck infection.
  • Do not prescribe antibiotics solely for tonsillar exudate without the indicated diagnostic pathway.
