Expert Committee recommendation
The Expert Committee noted that the appropriate first-line treatment option for otitis media is watchful waiting, symptom relief and no antibiotic treatment, unless a child is under 2 years of age with bilateral otitis media. The Committee endorsed the inclusion of amoxicillin as first-choice therapy and amoxicillin + clavulanic acid as second-choice therapy in suspected bacterial otitis media.
Acute otitis media is one of the most common infections in children. There has been controversy about the best approach, that is, whether otitis media should include early therapy or watchful waiting. On the one hand, avoidance of antibiotics could reduce resistance, adverse events and cost; on the other, concern has been raised about suppurative complications of otitis media if left untreated.
Summary of evidence
A 2015 Cochrane review of 13 randomized controlled trials (RCTs; 3401 children) showed that antibiotics had not reduced pain at 24 hours after the start of treatment (risk ratio (RR) 0.89; 95% confidence interval (CI) 0.78–1.01) but almost a third fewer treated children had residual pain at 2–3 days (RR 0.70; 95% CI 0.57–0.86) (1). Immediate treatment with antibiotics was not associated with a reduction in the number of children with pain (RR 0.91, 95% CI 0.75 to 1.10) compared with expectant observation. Antibiotics did reduce the number of children with tympanic membrane perforations (RR 0.37: 95% CI 0.18–0.76) but not abnormal tympanometry at 3 months (RR 0.97; 95% CI 0.76–1.24) or the number of children with late acute otitis media recurrences (RR 0.93; 95% CI 0.78–1.10). Adverse events such as vomiting, diarrhoea and rash occurred more often in children taking antibiotics than in placebo-treated children (RR 1.38; 95% CI 1.19–1.59). A 2013 Cochrane review (5 RCTs, 1601 children) showed that one or two daily doses of amoxicillin, with or without clavulanic acid, were comparable to three or four doses for clinical cure at the end of therapy (RR 1.03; 95% CI 0.99–1.07), during therapy (RR 1.06; 95% CI 0.85–1.33) and at follow-up (RR 1.02: 95% CI 0.95–1.09) (2).
Guidelines of the American Academy of Pediatrics and Family Physicians and of the Canadian Paediatric Society recommend treatment of acute otitis media in children with significant pain for longer than 48 hours and/or fever of 39 °C or higher (3, 4). The Canadian Paediatric Society guidelines recommend amoxicillin as the antibiotic of choice when it is felt that acute otitis media should be treated with antibiotics (3). The American Academy of Pediatrics and Family Physicians recommend amoxicillin (but suggest amoxicillin + clavulanic acid if a child has already been exposed to amoxicillin in the previous 30 days) and cephalosporins for patients with allergy to penicillin (cefdinir, cefuroxime, cefpodoxime and ceftriaxone) (4).
Rationale for antibiotic selection
Antibiotics may not be needed for otitis media and a strategy of watchful waiting may reduce unnecessary antibiotic use. Unless a child is under 2 years of age with bilateral otitis media (4), no antibiotics is a perfectly reasonable first-line option. Amoxicillin is the core antibiotic choice; amoxicillin + clavulanic acid is another option. Cefuroxime or ceftriaxone can be used for severe cases, minimizing exposure to third-generation cephalosporins.
Committee considerations
For common community-acquired infections, the main focus has been on empirical treatment choices that are broadly applicable in most countries. Generally, alternatives for use in case of allergy were not considered. The Expert Committee considered the various antibiotics proposed in the application under the guiding principle of parsimony and selected first- and second-choice antibiotics for this indication for inclusion on the EML and/or EMLc. Ceftriaxone and cefuroxime were excluded. Recommended first- and second-choice antibiotics are reported above. The first-choice antibiotics are those generally recommended on the basis of available evidence and are usually narrow-spectrum agents.
