Epidemiological assessment of geographic and socioeconomic disparities in myringotomy procedures among First Nations children in South Australia
Bibliographic record
Abstract
OBJECTIVE: Australian First Nations children bear 8.5 times greater burden of early and recurrent ear and nasopharyngeal infections compared with non-Indigenous children. These disparities are compounded by structural inequities in access to healthcare. To better understand these patterns, we analysed the state-wide epidemiology of childhood myringotomy procedures in South Australia and conducted spatial analysis for its main metropolitan region-Adelaide-to examine the associations with socioeconomic status and distance to healthcare facilities. DESIGN AND SETTING: A cross-sectional, population-wide study. PARTICIPANTS: All persons who had myringotomy procedures performed between 2007 and 2022. PRIMARY AND SECONDARY OUTCOME MEASURES: Annual, age and sex-specific incidence was calculated at the local scale (Statistical Area level 2, SA2). We used admitted patient care data from SA Health, providing comprehensive coverage of otitis media procedures across the population, including First Nations. We applied negative binomial regression to assess associations with socioeconomic status and distance to healthcare facilities, accounting for count-based data and overdispersion. RESULTS: Myringotomy incidence among First Nations children ranged from 2.2 to 6.1 per 1000 child-years across SA2 regions, compared with 2.4 to 3.7 among non-indigenous children. For the whole population, overall annual incidence ranged from 2.7 to 4.2 for males and 2.0 to 2.9 for females, with higher incidence observed in several suburban areas of Adelaide. Myringotomy procedures were associated with socioeconomic status, with increased socioeconomic advantage associated with a 17% reduction in cases (relative risk 0.83, 95% CI 0.76 to 0.92) among First Nations children. Distance to healthcare facilities was associated with myringotomy for non-indigenous children but not for First Nations children. CONCLUSIONS: This study found a higher incidence of myringotomy procedures among First Nations children, particularly in later childhood. Socioeconomic disadvantage was a driver, while geographic proximity to healthcare had limited influence. Future initiatives may benefit by prioritising culturally informed, community-led strategies focused on early intervention, prevention and equitable service delivery.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
