🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
Influenza and other respiratory viruses (2026) - Systematic Review
Key Findings
- RSV accounted for 16.9% of pediatric AOM cases in the pooled estimate.
- Among RSV-positive AOM cases, 67.4% had at least one bacterial co-detection.
📋 Practice Implication: RSV-season AOM planning should account for viral-bacterial overlap and the possible downstream value of RSV prevention strategies.
|
Vaccine (2026) - Systematic Review
Key Findings
- AOM incidence in children 2 years or younger was 16.07 per 1000 person-years with PCV vaccination vs 34.26 without vaccination.
- Haemophilus influenzae caused 31.81% of AOM in children 2 years or younger, versus 19.35% for Streptococcus pneumoniae.
📋 Practice Implication: Persistent vaccine-era AOM should prompt attention to non-typeable Haemophilus influenzae and residual pneumococcal serotypes.
|
BMC infectious diseases (2026) - Meta-Analysis
Key Findings
- Across 1,331,407 individuals, PCV did not consistently reduce AOM in some pediatric subpopulations and settings.
- The vaccine group had increased recurrent AOM risk in the pooled analysis, with RR 1.053 and 95% CI 1.040-1.065.
📋 Practice Implication: Vaccine counseling should remain supportive of immunization while avoiding overstatement of protection against all-cause AOM.
|
The Cochrane database of systematic reviews (2025) - Systematic Review
Key Findings
- Antihistamines produced little to no difference in otitis media with effusion at 10 to 14 days versus placebo, with RR 1.13 and 95% CI 0.89-1.45.
- Decongestants had very uncertain effects on adverse events compared with placebo, with RR 3.60 and 95% CI 0.16-83.28.
📋 Practice Implication: Routine decongestant or antihistamine use for pediatric AOM should be avoided unless another clear indication exists.
|
International journal of pediatric otorhinolaryngology (2025) - Systematic Review
Key Findings
- Children had a 20% greater risk of intracranial complication after the COVID pandemic than before, with RR 1.2 and p = 0.0097.
- Conservative antibiotic-only treatment decreased after the pandemic by 10.8%, with 95% CI 2.9%-18.0% and p < 0.01.
📋 Practice Implication: Pediatric mastoiditis presentations in the post-pandemic period warrant earlier escalation when complications are clinically plausible.

💡
Summary
Recent evidence for otitis media centers on pediatric acute otitis media prevention, residual bacterial burden after pneumococcal vaccination, and avoidance of ineffective adjunctive medications. Complication-focused data also suggest that post-pandemic pediatric mastoiditis may present with greater intracranial risk, supporting earlier escalation when severe features are present.
