Summary
Danish general practitioners (GPs) use strict criteria for diagnosing acute otitis media. Improving diagnostic certainty involves better ear canal visualization and using pneumatic otoscopy.
Area of Science:
- Otolaryngology
- General Practice
- Diagnostic Accuracy
Background:
- Acute otitis media (AOM) diagnosis relies on specific clinical criteria.
- Diagnostic uncertainty in AOM can impact patient care and treatment outcomes.
Purpose of the Study:
- To assess the diagnostic criteria and performance of general practitioners (GPs) in diagnosing AOM in Denmark.
- To identify the extent and reasons for diagnostic uncertainty in AOM cases.
Main Methods:
- A survey was conducted among 568 GPs to assess diagnostic criteria for AOM.
- Prospective registration of 368 consultations for AOM in children was performed to evaluate GP performance.
- Multivariate analysis was used to identify factors predicting diagnostic certainty.
Main Results:
- Key diagnostic criteria included earache, fever, reduced hearing, bulging eardrum, red eardrum, and purulent otorrhea.
- Diagnostic certainty for AOM was 67% in children under 2 and 75% in older children.
- A satisfactory view of the eardrum (OR 11.0) and purulent otorrhea (OR 10.1) were the strongest predictors of diagnostic certainty.
Conclusions:
- Danish GPs employ stricter AOM diagnostic criteria compared to international standards.
- Diagnostic accuracy can be enhanced through ear canal cleaning and pneumatic otoscopy.
- Discrepancies between diagnostic criteria and actual performance were minimal.
