Percentage of OM visits resulting in antibiotic prescriptions and percentage of OM visits with antibiotic prescriptions in which broad-spectrum antibiotics were prescribed for children ≤14 years old, 2008–2010. Broad-spectrum antibiotics included macrolides, quinolones, broad-spectrum penicillins (β-lactam/β-lactamase inhibitor combinations), lincomycin derivatives, and second- to fourth-generation cephalosporins.
Distribution of broad-spectrum antibiotic prescriptions in children ≤14 years old with OM by class and race, 2008 to 2010. Visits where clindamycin was prescribed (n = 2) were too few to display. *Estimate for quinolones in black children are based on <30 observations.
Number of Annual Ambulatory Visits, Percentage of All Ambulatory Visits, and Ambulatory Rates in Number of Visits per 1000 Population by Age Group and Race for OM and All Respiratory Conditions, 2008–2010
Average Annual Number of Visits in Millions (95% CI)
↵b A diagnosis of OM was assigned using ICD-9-CM codes 381–382 in any of the 3 diagnosis fields; 80.4% of OM visits used ICD-9-CM code 382.9 (unspecified otitis media) versus 11.4% for all 381 ICD-9-CM codes (nonsuppurative otitis media and eustachian tube disorders).
↵c Respiratory diagnoses included ICD-9-CM 460–520 (“respiratory” category), as well as mastoiditis (383), allergy (995.3), otitis media (381–382), and streptococcal sore throat (034).
Factors Associated With Broad-Spectrum Antibiotic Prescribing for OM in Children ≤14 y Old
Proportion (95% CI) of Broad-Spectruma Antibiotics, at Visits With Antibiotics Prescribed
Adjusted OR for Broad-Spectrum Prescribing (95% CI)
↵a Percentages reflect the proportion of antibiotics that were broad-spectrum agents. Broad-spectrum antibiotics included macrolides, quinolones, broad-spectrum penicillins (including β-lactam/β-lactamase inhibitor combinations), clindamycin, and broad-spectrum (second- to fourth-generation) cephalosporins.
↵b Data on physician specialty are for offices only. Thus, the odds ratio for specialty is from a separate model that included data from visits to offices only.
