Abstract
Objective: The aim of this study was to determine the incidence of inner ear involvement in various forms of acute otitis media (AOM) in ear, nose, and throat (ENT) practices in Germany. Methods: Patients who had been diagnosed with various forms of AOM in the years 2010 to 2017 were enrolled in the study from a nationwide, representative practice database (Disease Analyzer, IQVIA). In these patients, the incidence of simultaneous or subsequent inner ear disorders (IED) was determined within 7 days and within 12 months from the date of an AOM diagnosis. Results: A total of 286 186 patients with AOM were enrolled. The most frequent diagnoses were “nonsuppurative otitis media, unspecified” (47.6%) and “otitis media, unspecified” (39.0%). The diagnoses of hemorrhagic bullous myringitis (BM) or influenza-induced AOM were very rarely found in the database. The highest incidence of IED after 7 days and 12 months was found in “nonsuppurative otitis media, unspecified” (7.7% and 15.9%, respectively), followed by “otitis media, unspecified” (5.6% and 13.5%, respectively). The incidences of the most frequent IED “hearing loss, unspecified” and “sensorineural hearing loss, unspecified” increased proportionally with increasing patient age, while the rare diagnoses of “labyrinthitis” and “ototoxic hearing loss” were evenly distributed among the age groups. Conclusion: In ENT practices in Germany, both various forms of AOM, as well as simultaneous or subsequent IED, are mostly being coded in an unspecific way, while specific forms such as hemorrhagic BM, influenza-induced AOM, and labyrinthitis are coded very rarely. Older patients have a higher risk of IED in AOM. A visit due to AOM seems to be a regular occasion for the initial diagnosis of hearing impairment in the elderly individuals. The highest risk of IED was found in nonsuppurative AOM.
