Background:
Recommendations on withholding antibiotics in children with acute otitis media (AOM) have been inadequately implemented in clinical practice.
Objectives:
We evaluated the role of prescribing antibiotics for AOM.
Methods:
We performed a meta-analysis of randomized controlled trials (RCTs) that were retrieved from searches performed in the PubMed and Cochrane databases, and compared antibiotic treatment with placebo or watchful waiting (delayed antibiotic treatment if clinically indicated) for patients with AOM.
Results:
We identified seven trials comparing antibiotic treatment with placebo (all double-blinded) and four trials comparing antibiotic treatment with watchful waiting (two investigator-blinded and two open-label) trials, all of which involved children (6 months to 12 years). Clinical success was more likely with antibiotics than comparator treatment in: placebo-controlled trials [seven RCTs, 1405 patients, risk ratio (RR) = 1.11, 95% confidence interval (CI) = 1.05-1.18]; watchful waiting trials (four RCTs, 915 patients, RR = 1.18, 95% CI = 1.07-1.32); and all trials combined (11 RCTs, 2320 patients, RR = 1.13, 95% CI = 1.08-1.19). Similarly, persistence of symptoms 2-4 days after treatment initiation was less likely with antibiotics in: placebo-controlled trials (four RCTs, 1014 patients, RR = 0.75, 95% CI = 0.64-0.88) and all trials combined (five RCTs, 1299 patients, RR = 0.68, 95% CI = 0.54-0.85). Diarrhoea was more likely with antibiotics (seven RCTs, 1807 patients, RR = 1.50, 95% CI = 1.16-1.95). No differences between the compared treatments were found regarding other effectiveness and safety outcomes.
Conclusions:
Antibiotic treatment is associated with a more favourable clinical course in children with AOM, compared with placebo, and also compared with watchful waiting. However, safety issues and the rather small treatment effect difference render the consideration of additional factors necessary in relevant clinical decision making.
Insights
Antibiotic treatment improves clinical outcomes for children with acute otitis media (AOM) compared to placebo or watchful waiting. However, potential side effects and modest benefits necessitate careful consideration in clinical decisions.
Area of Science:
- Pediatrics
- Infectious Diseases
- Pharmacology
Background:
- Clinical practice inadequately implements recommendations for withholding antibiotics in children with acute otitis media (AOM).
- Antibiotic use in AOM is a significant clinical decision point with varying guidelines.
Purpose of the Study:
- To evaluate the efficacy and safety of prescribing antibiotics for acute otitis media in children.
- To compare antibiotic treatment versus placebo or watchful waiting for AOM management.
Main Methods:
- A meta-analysis of randomized controlled trials (RCTs) was conducted.
- Searches were performed in PubMed and Cochrane databases.
- Included trials compared antibiotic treatment with placebo or watchful waiting in children aged 6 months to 12 years.
Main Results:
- Antibiotic treatment led to higher clinical success rates compared to placebo (RR=1.11) and watchful waiting (RR=1.18).
- Symptom persistence was reduced with antibiotics (RR=0.68 for all trials combined).
- Diarrhea was a more frequent side effect with antibiotic use (RR=1.50).
Conclusions:
- Antibiotic therapy is associated with a more favorable clinical course in pediatric AOM.
- The modest treatment effect difference and safety concerns, such as increased diarrhea, require careful consideration in clinical decision-making.
- Further evaluation of individual patient factors is necessary for optimal AOM management.

Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
