Abstract

Objective

To compare the asynchronous assessment of video otoscopic still images to recordings by an audiologist and ear, nose and throat surgeon (ENT) for diagnostic reliability and agreement in identifying middle-ear disease.

Design

A prospective cross-sectional study, asynchronously assessing video otoscopy, tympanometry and case history (Dx1). A subset was re-diagnosed (Dx2).

Study sample

Video otoscopy and data from 146 children recruited at two public community events; a sub-set of 47 were re-assessed.

Results

The intra-rater diagnostic agreement between Dx1 and Dx2 was moderate (k = 0.445–0.552) for the ENT surgeon, and almost-perfect (k = 0.928) for the audiologist, in both procedures. The agreement between the two procedures was substantial (k = 0.624) and moderate (k = 0.416) for the ENT surgeon in Dx1 and Dx2 respectively, and almost-perfect for the audiologist (k = 0.854–0.978) in both rounds. In Dx1, the inter-rater agreement between the clinicians was substantial using still images (k = 0.672) and moderate using recordings (k = 0.593); in Dx2 it was moderate using both procedures (k = 0.477–0.488).

Conclusion

Both video otoscopic procedures, in addition to tympanometry and case history information, can be reliably used for asynchronous diagnosis of childhood middle-ear disease. An audiologist has a potential role in triaging children with middle-ear abnormalities and, therefore, improving access to ear-health services.
