Children frequently present with "pink eye" to the ED. When they do, parents often expect antibiotics. How many of these kids actually need them? Previous studies have shown approximately 54% of acute conjunctivitis was bacterial, but antibiotics were prescribed in 80-95% of cases.
A prospective study in a suburban children's hospital published in 2007, showed that 87% of the cases during the study period were bacterial. The most common type of bacteria was nontypeable H. influenza followed by S. pneumoniae.
Topical antibiotic treatment has been shown to improve remission rates by 6-10 days.
