Acute Uncomplicated Bacterial Rhinosinusitis (ABRS)
Treatment Criteria & Considerations
- Purulent nasal drainage accompanied by nasal obstruction, facial pain-pressure-fullness, or both lasting less than 4 weeks
Colour of nasal discharge or sputum is related to the presence of neutrophils, not bacteria, and should not be used alone to diagnose bacterial rhinosinusitis
However, it is important to note that facial pain-pressure-fullness WITHOUT purulent nasal discharge is not sufficient for a diagnosis of acute bacterial rhinosinusitis.
Clinical diagnosis and differentiation of acute bacterial from viral rhinosinusitis is based on the characteristic patterns of clinical presentations taking into account duration of symptoms, severity of illness, temporal progression and "double-sickening" in the clinical course
The following clinical presentations (any of the 3) are recommended for identifying patients with acute bacterial vs. viral rhinosinusitis:
- Onset with persistent symptoms or signs compatible with acute rhinosinusitis, lasting for ≥10 days without any evidence of clinical improvement.
- Onset with severe symptoms or signs of high fever (≥39°C) and purulent nasal discharge or facial pain lasting for at least 3 to 4 consecutive days at the beginning of illness.
- Onset with worsening symptoms or signs characterized by the new onset of fever, headache or increased nasal discharge following a typical viral upper respiratory infections that lasted 5-6 days and were initially improving ("double sickening").
These guideline recommendations are not intended for patients with complicating factors, such as immune deficiency or uncontrolled diabetes
Watchful waiting should not be used for patients with complicating factors and they should be started promptly on appropriate antimicrobial therapy
