Rhinosinusitis EPOS

Rhinosinusitis Severity (EPOS): Symptom-weighted EPOS-style severity and bacterial red flags for acute rhinosinusitis.

Clinical Factors

Assessment Tier

Likely Viral

Score 0

Supportive care is usually appropriate.

Guidelines & Evidence

Clinical Details

Section 1

When to Use

Use during early bedside triage when infection severity or treatment escalation is uncertain.

Support clinician judgement with a structured review of the highest-yield risk factors.

Standardise communication between admitting, ID, ICU, and pharmacy teams.

Section 2

Formula & Logic

Scoring Logic

Severe facial pain or pressure (+1)

Purulent discharge predominates (+1)

Symptoms >10 days without improvement (+2)

Double-worsening after initial viral illness (+2)

Fever ≥38°C (+1)

Orbital or neurologic complication red flags (+3)

Section 3

Next Steps

Clinical Actions

Interpret the result together with source control, microbiology, host factors, and trajectory.

Escalate imaging, cultures, or specialist review when the tool lands in a high-risk tier.

Reassess dynamically if the patient deteriorates or new microbiology becomes available.

Section 4

Pearls/Pitfalls

Important Caveat

This tool supports structured infectious-disease decision making but does not replace clinician judgement or local guideline pathways.

Section 5
