Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Children randomised to the ‘additional examination’ group will receive the standard of care (control group) plus an additional clinical ear examination by an Aboriginal Ear Health Practitioner (AEHP). This clinical ear examination includes tympanometry, video-otoscopy and a hearing screen and will take between 30 and 60 minutes. Ear examinations will be conducted as soon after the child is admitted into hospital as possible. The child's discharge plan will be updated based on the findings of the examination. A recommended management plan will be created based on the "2020 Otitis Media Guidelines for Aboriginal and Torres Strait Islander Children" and suggested for implementation by the treating medical team. Adherence to this intervention will be via audit of the electronic medical records up to 3 months after hospital discharge. The AEHP will spend time with the family of the child regularly (approximately daily) until the child is discharged from hospital. This time will be used to educate the family about ear health management, as well as offering more general health advice and support in the hospital environment. Time spent with each family will vary depending on the family's needs.
Families in both the intervention and control groups will receive printed educational material regarding the five most important chronic conditions affecting children in Royal Darwin Hospital: severe otitis media; early childhood malnutrition; iron deficiency anaemia; chronic suppurative lung disease; and acute rheumatic fever. These materials are from readily available resources, such as RHD Australia, Bronchiectasis Toolbox, Department of Health etc.

Comparator / control treatment
Children in the control arm will receive the usual standard care from the treating hospital medical team. It is expected that standard care would include a discussion about the proposed discharge plan with the family. The treating medical team will determine how this discussion occurs (ie. whether Aboriginal staff are involved or not) consistent with their normal practice. Any ear health discharge planning including in this will be dependent on the routine clinical examinations conducted by hospital staff.

Outcomes
Primary outcome [1] 328792 0
The difference in proportion of children with clinical failure. Participants will be categorised by a blinded clinical outcome assessment of the electronic medical records documenting a visit to the child's local community clinic as follows:
1. Clinically Inactive: no supporative or severe otitis media, or unilateral otitis media with effusion and no recommendation of any treatment, hearing support or clinical review
2. Clinically Active on Appropriate Treatment: current suppurative or severe otitis media but currently following appropriate treatment plan
3. Clinically Active and Needs Treatment: current suppurative or severe otitis media which requires treatment, but not currently following appropriate treatment plan
4. Clinically Active and Failed Treatment: current suppurative or severe otitis media, currently following appropriate treatment plan but condition worsening or not responding to treatment
Categories 3 and 4 would be deemed “clinical failure”.

3 months post hospital discharge
Secondary outcome [1] 400362 0
Proportions of children with adherence to recommended management of ear disease between the two groups (where a recommended management plan exists in the Control Group as part of routine care). Adherence success is defined as attending >80% recommended clinic reviews and taking >80% prescribed medications and will be assessed by a blinded review of the electronic medical records,
Timepoint [1] 400362 0
up to 3 months post hospital discharge
Secondary outcome [2] 400363 0
Proportions of children with clinical complications, as assessed by a blinded review of the electronic medical records, Clinical complications include extracranial complications (for example mastoiditis and cholesteatoma) and intracranial complications (for example meningitis, brain abscess and sigmoid sinus thrombosis).
Timepoint [2] 400363 0
up to 3 months post hospital discharge
Secondary outcome [3] 400364 0
Proportions of children with serious adverse events (SAEs). Due to the nature of the intervention we anticipate that SAEs will be rare. A serious adverse events (SAE) is an undesirable experience occurring during the intervention period that:
o Results in death
o Is life-threatening
o Results in hospitalisation (initial or prolongation)
o Results in disability or permanent damage
Assessment will be by blinded assessment of the electronic medical records,

Secondary outcome [6] 400367 0
The sensitivity and specificity of both the routine clinical ear assessment (where available) and the AEHP's ear health examination. An expert in the field will provide an independent assessment of the videos and photos obtained by the AEHP's ear health examination to act as the 'gold standard'. Both the AEHP's ear health examination assessment and the information in the hospital notes regarding the routine clinical ear assessment will be compared to this 'gold standard'.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involves contacting the holder of the allocation schedule who is off-site. Eligibility will be determined by person on-site at the Royal Darwin Hospital and allocation will be carried out after study enrollment by another person at the Menzies School of Health Research.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (RedCap). Randomisation will be stratified by:
i) whether the participant's current place of residence is inside or outside of the Darwin and Palmerston local council areas.
ii) age of participant either 0-5 years of 6 years and over

Efficacy
Statistical methods / analysis
The primary clinical outcome analysis will report the difference in proportion (and 95% confidence interval) of children with clinical failure at 3 months post hospital discharge. Unadjusted differences in clinical failure will be assessed by the Chi-squared test. An adjusted model will include stratification factors using a binomial regression model. Risk difference and relative risk estimates will be reported.

We will follow the “intention to treat” principle but only use the available data (ie. there will be no imputation for missing values). The number of children with completely missing primary outcome data (ie. where there is no medical record available for review) will be described. This number is expected to be small (<5% of randomised children) and the same in each arm. Sensitivity analyses will involve a “per protocol” approach based on successful AEHW-led discharge and adjustment for potential confounders.

Secondary outcome assessment of proportions of children with:
i) adherence to recommended recommended management of ear disease between the two groups;
ii) clinical complications and
iii) serious adverse events (SAEs)
will be compared between the two groups using Chi-square test (reported as absolute risk difference and 95% CI).

Secondary outcomes of family satisfaction with both discharge planning and overall hospital care will be compared between the two groups using Student’s t-test (reported as difference in mean and SD, 95% CI). Pre-specified subgroup analyses will be conducted according to whether the family speak English as a first language or not.

The sample size is calculated to allow detection of a difference of 13% in clinical failure. This assumes that clinical failure will be reduced from 33% to 20%. A difference of 13% in clinical outcomes is modest but would be clinically important. Assuming we have data on more than 512 children available for analysis, the power of the study will be >90% (at the 5% significance level). A total sample of 600 (300 per group) children will allow for an attrition rate up to 15%.
