The disease burden of untreated chronic otitis media in Indigenous children from remote communities does not improve over time. A longitudinal study

Abstract: BACKGROUND: In Australia, middle ear disease disproportionately affects Indigenous children, leading to poor hearing outcomes. This study aimed to determine the natural history of untreated chronic otitis media in Indigenous children in remote South Australia. METHODS: Baseline and 3 year follow-up data was collected from Indigenous children aged 5-18 years living on the Anangu Pitjantjatjara Yankunytjatjara Lands. 4-frequency pure-tone audiometry was used to determine hearing levels. Middle ear pathology was determined by video-otoscopy with tympanometry and classified at baseline as group 1 (normal), group 2 (abnormal with intact tympanic membrane), or group 3 (perforated tympanic membrane). RESULTS: A total of 253 children were included in this study. Children in group 1 (20.6 ± 1.5 dBHL; Mean ± SD) had significantly better hearing outcomes at 3 year follow-up than children with abnormal ears (groups 2 and 3) (23.8 ± 7.0 dBHL), P < 0.001. The difference was greatest for group 1 versus 3 (27.6 ± 8.4 dBHL), P < 0.001, followed by 1 versus 2 (22.4 ± 5.8 dBHL), P = 0.009, and between 2 (22.4 ± 5.8 dBHL) and 3 (27.6 ± 8.4 dBHL), P < 0.001. CONCLUSION: Hearing in Indigenous children with untreated middle ear pathology remains poor at follow-up compared to those without pathology. Intervention is therefore critical to prevent persisting poor hearing outcomes.
