Variation in rates of diagnosis of acute otitis media
Insights
Weekly acute otitis media diagnostic rates in children varied significantly, driven by individual provider differences. Junior residents
Area of Science:
- Pediatrics
- Infectious Diseases
- Healthcare Quality
Background:
- Acute otitis media (AOM) is a common childhood infection.
- Accurate diagnosis is crucial for appropriate treatment and preventing complications.
- Variability in diagnostic rates can impact patient care and resource allocation.
Purpose of the Study:
- To investigate the temporal variation in acute otitis media diagnostic rates among febrile children in a pediatric emergency room.
- To identify factors contributing to the observed diagnostic rate variability.
Main Methods:
- A 13-week monitoring period across two phases in 1978.
- Inclusion of febrile children aged one to five years presenting to a large children's hospital emergency room.
- Analysis of weekly diagnostic rates for acute otitis media.
Main Results:
- Of 228 eligible children, 53 (23%) were diagnosed with otitis media.
- Weekly diagnostic rates showed statistically significant variation (p < .005) beyond expected levels.
- Temporal variations were primarily linked to individual provider differences, not training level.
- Short-term learning by junior residents during their emergency room rotation significantly influenced week-to-week diagnostic rate fluctuations.
Conclusions:
- Significant week-to-week variability exists in acute otitis media diagnosis rates in pediatric emergency settings.
- Individual provider practice patterns are a major driver of diagnostic variability.
- The learning curve for junior residents impacts diagnostic consistency during short rotations.
Abstract:
Over 13 weeks during two periods in 1978 the diagnostic rate for acute otitis media was monitored among febrile children (aged one to five years) in the emergency room of a large children's hospital. Of the total 228 eligible children, 53 (23 percent) were diagnosed as having otitis media. The observed variation in the weekly diagnostic rates was significantly (p < .005) greater than that expected if the diagnosis rate were a constant 23 percent. Temporal variation in diagnostic rates was largely attributable to differences among individual providers and independent of level of training. For junior residents short-term learning, within the seven-week emergency room rotation, contributed significantly to the week-to-week temporal variation in diagnostic rates for acute otitis media.
