Interrater agreement on tympanometry in infants

Area of Science:

• Audiology
• Pediatrics
• Otolaryngology

Background:

• Tympanometry is crucial for diagnosing middle ear conditions in infants.
• Standardized interpretation protocols are essential for reliable results.
• Interrater reliability in infant tympanometry can be challenging.

Purpose of the Study:

• To assess interrater agreement in infant tympanometry interpretation.
• To identify factors influencing agreement among healthcare professionals.
• To evaluate the effectiveness of a standard operating procedure.

Main Methods:

• Two hundred forty-two infant tympanograms were independently interpreted by an audiologist and ten study doctors.
• Interpretation followed a standardized operating procedure.
• Kappa index was used to measure interrater agreement.

Main Results:

• Excellent interrater agreement was observed among study doctors (kappa = 0.80) and between the audiologist and doctors (kappa = 0.77).
• Agreement was better during healthy visits than sick visits (p < 0.001).
• Knowledge of clinical ear status improved agreement on abnormal curves (p < 0.001).

Conclusions:

• High interrater agreement in infant tympanometry is achievable with adequate training and standardized procedures.
• Clinical context significantly enhances the accuracy of interpreting abnormal tympanometric findings.
• Infant age did not impact interpretation agreement.
