Three-Part Question:
In [a systemically well child with otitis media] are [oral antibiotics better than placebo] at [decreasing time to recovery and reducing the incidence of secondary complications]?
Clinical Scenario:
A 2 year old child is brought into the emergency department with a general malaise and irritability for the last 24 hours. Examination of the right ear reveals a diffusely red bulging ear drum. A diagnosis of acute otitis media is made. You wonder whether there is any evidence that oral antibiotics would decrease the time to recovery and prevent secondary complications.
Search Strategy:
Medline 1966-11/00 using the OVID interface.

Outcome:
865 papers were found of which 10 were relevant and had been meta-analysed by the Cochrane review group which was last updated on 28/04/2000. No further relevant papers have been published since. A meta-analysis done in 1994 was also selected.

Antibiotics vs no antibiotics
Systematic review Hearing between 1 and 3 months No significant difference Only one episode of mastoiditis in all the trials
Pain between 2 and 7 days 28% (CI 15%-38%) relative reduction with antibiotics (NNT=17)
Pain at 24 hours No difference
