Abstract:
Finnish guidelines recommend antimicrobial treatment for acute otitis media (AOM), with both amoxicillin and amoxicillin-clavulanate as equally acceptable first-line treatment options. This study aimed to investigate in what proportion different antimicrobial agents are prescribed for children with AOM. Our hypothesis was that amoxicillin is the most frequently prescribed antimicrobial agent. This register-based cohort study included all children less than 16 years of age with a diagnosis of AOM in two Finnish hospitals in 2023. Data on children's demographics, AOM symptoms, findings and treatment were collected individually from the patient charts. The primary outcome was the proportion of children who were prescribed amoxicillin, amoxicillin-clavulanate, or other antimicrobial agents for the treatment of AOM. The antimicrobial treatment choices and durations were compared between Turku and Vaasa and reported as percentage differences with 95% confidence intervals. A total of 1,240 children in Turku and 393 children in Vaasa were included in this study. Among these, 80.9% (1,003/1,240) and 80.7% (317/393) were prescribed amoxicillin for the treatment of AOM in Turku and Vaasa, respectively. Amoxicillin-clavulanate was the second most used antimicrobial treatment, prescribed to 10.1% (125/1,240) and 8.7% (34/393) of the children in Turku and Vaasa, respectively. Most of the children with AOM were prescribed a short 5-day course of treatment.
Conclusion:
A short 5-day course of amoxicillin was the most frequently prescribed antimicrobial treatment for children with AOM. The adherence to AOM guidelines appears to be high in the two hospitals studied.
What Is Known:
• Amoxicillin and amoxicillin-clavulanate are recommended as first-line treatments for acute otitis media in Finland. • National data on real-world antibiotic choices have been limited.
What Is New:
• Amoxicillin was the most frequently prescribed antibiotic in the two Finnish hospitals studied. • The most common treatment duration was a short 5-day course of treatment.
Insights
Amoxicillin was the most prescribed antibiotic for acute otitis media (AOM) in Finnish children, with most receiving a short 5-day course. This indicates high adherence to AOM treatment guidelines in the studied hospitals.
Area of Science:
- Pediatrics
- Infectious Diseases
- Pharmacology
Background:
- Finnish guidelines recommend amoxicillin and amoxicillin-clavulanate for acute otitis media (AOM).
- Limited national data exists on real-world antibiotic prescribing for AOM.
Purpose of the Study:
- To determine the proportion of different antimicrobial agents prescribed for pediatric AOM.
- To test the hypothesis that amoxicillin is the most frequently prescribed agent.
Main Methods:
- Register-based cohort study of children under 16 with AOM in two Finnish hospitals (2023).
- Data collected from patient charts on demographics, AOM symptoms, findings, and treatment.
- Primary outcome: proportion of children prescribed amoxicillin, amoxicillin-clavulanate, or other agents.
Main Results:
- Amoxicillin was prescribed to 80.9% in Turku and 80.7% in Vaasa.
- Amoxicillin-clavulanate was the second most used (10.1% and 8.7% respectively).
- The majority of children received a short 5-day treatment course.
Conclusions:
- A short 5-day course of amoxicillin is the most frequent antimicrobial treatment for pediatric AOM.
- High adherence to AOM treatment guidelines observed in the studied hospitals.
