Treatment of acute otitis media: are children entered into clinical trials representative?

Area of Science:

• Pediatrics
• Clinical Research Methodology

Background:

• Acute otitis media (AOM) is a common childhood illness.
• The efficacy of antibiotics in treating AOM is a subject of ongoing research and clinical debate.

Purpose of the Study:

• To critically evaluate the methodological characteristics of randomized controlled trials (RCTs) for AOM treatment.
• To assess how trial design and participant recruitment impact the interpretation of AOM treatment outcomes.

Main Methods:

• A meta-analysis of existing randomized controlled trials (RCTs) on AOM treatment was conducted.
• Key trial characteristics including methods, participant age groups, interventions, and outcomes were systematically reviewed.
• An in-depth investigation of eight specific trials was performed.

Main Results:

• Analysis revealed a low number of children recruited per physician across the included trials.
• The overall patient recruitment rate was estimated to be below 44%.
• Low recruitment rates may lead to a selection bias, with participants potentially having milder disease presentations.

Conclusions:

• The study suggests that low recruitment rates in AOM RCTs might skew results.
• This potential bias could explain findings indicating that antibiotics are not essential for treating acute otitis media.
• Further research should address recruitment strategies to improve trial generalizability.
