Treatment Failure in Acute Otitis Media: A Clinical Study of Children during Their First Three Years of Life

Abstract

Although little is known about the occurrence of treatment failure in acute otitis media (AOM), available data suggest that it may be over-diagnosed. In the present study the frequency of treatment failure in AOM was determined in 113 children followed for 3 years from birth. Of 300 AOM episodes, 293 (in 70 children) were treated with oral antibiotics, and children under 10-11 months of age usually underwent myringotomy as well. During the observation period, there were 22 instances (in 16 children) of failure to respond to the primary antibiotic treatment of the AOM episodes. The annual frequency of treatment failure was 18.5%, 4.5% and 4.2% during the first, second and third years of life, respectively. The risk of failure to respond to antibiotic treatment was greater during the first year of life than during the following 2 years. The bacteria isolated and the choice of drug seemed to be of secondary importance.
