Management of otitis media among children in a large health insurance plan.

Abstract

Otitis media is one of the most common office diagnoses among children in the US and the leading reason for the use of antimicrobials in pediatric practice. We undertook this study to characterize medical and surgical management of otitis media. Using claims data from a large New England health insurer, we identified all children <10 years of age who had one or more episodes of acute otitis media between July, 1995, and June, 1996, and examined patterns of treatment for this condition. Study subjects (n = 22,004) averaged 2.9 physician office visits for management of otitis media; among children <2 years of age, one-fourth had 6 or more such visits. Amoxicillin was prescribed as initial therapy in more than one-half (56.6%) of all episodes of acute otitis media, followed by cephalosporins (18.3%), trimethoprim-sulfamethoxazole (12.3%), macrolides (6.4%) and amoxicillin-clavulanate (6.0%). Over multiple episodes, however, use of amoxicillin declined by about 50%. Antimicrobial prophylaxis was received by 7.3% of all study subjects for a mean of 61.3 days; the incidence of breakthrough episodes of acute otitis media during prophylaxis varied according to the antimicrobial used (13.9, 12.3 and 19.5% for amoxicillin, trimethoprim-sulfamethoxazole and sulfisoxazole, respectively). Surgical procedures related to otitis media were performed on 3.8% of all study subjects, including 4.6% of children <2 years of age. The health care burden of otitis media is large, particularly in the first 2 years of life.
