Otitis media in children

Overview

Acute otitis media (AOM) is one of the most common childhood infections: pooled prevalence data report AOM as among the most common reasons for antibiotic prescribing in childhood, with high lifetime incidence in the first three years of life.^[1] The middle ear fills through a dysfunctional Eustachian tube following viral upper respiratory infection, and fluid becomes purulent.

The bacteriology is dominated by three organisms. In the Finnish otitis media cohort followed from 2 to 24 months, Streptococcus pneumoniae was isolated in 26%, Moraxella catarrhalis in 23% and Haemophilus influenzae in 23% of middle ear aspirates; Haemophilus was rare in first episodes (13%) but rose to about a third from the third episode onward.^[12] This distribution shifted after pneumococcal conjugate vaccination: population data spanning 2000–2018 showed AOM incidence halved (62 to 31 per 1000 population) in the PCV13 era, with antibiotic utilisation falling in parallel.^[6]
