Details for This Review

Study Population: Adults with suspected acute rhinosinusitis (symptoms for 30 days or fewer)

Efficacy End Points: Clinical cure (resolution or improvement of major symptoms)

Harm End Points: Adverse effects from antibiotic use

Narrative: Acute rhinosinusitis is a common condition encountered by clinicians in ambulatory and emergency department settings. It is characterized by inflammation of nasal passages and sinuses, resulting in purulent nasal discharge, sinus tenderness, and facial pain. Most cases are caused by a viral or self-limiting bacterial infection, neither of which require treatment with antibiotics.1 Despite longstanding guidelines that recommend limiting the use of antibiotics to a small subset of patients, most patients continue to be prescribed antibiotics.2

The Cochrane review examined data on benefits and harms associated with the use of antibiotics in adults with acute rhinosinusitis (symptoms for 30 days or fewer).3 The rate of clinical cure without antibiotics after one and two weeks was 46% and 64%, respectively. The definition of clinical cure varied depending on the study but was usually defined as resolution or improvement of major symptoms.

The Cochrane review categorized the participants into three groups: those with rhinosinusitis diagnosed clinically, radiographically, and by computed tomography (CT). The use of antibiotics was associated with a significant increase in the cure rate of clinically diagnosed rhinosinusitis (odds ratio [OR] = 1.25; 95% CI, 1.02 to 1.54; 5% absolute risk difference [ARD]; number needed to treat [NNT] = 19; high-quality evidence), radiographically diagnosed rhinosinusitis (OR = 1.57; 95% CI, 1.03 to 2.39; 10% ARD; NNT = 10; mode
