Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Support is provided to staff of Aboriginal Community Controlled Health Services. This support focuses on building staff capacity and systems to improve AUDIT-C screening rates, and to respond with appropriate clinical care if unhealthy drinking (hazardous use or alcohol use disorders) is detected. Support is composed of the following :
1. Services asked to nominate two project champions
2. Project champions attend a two-day national workshop provided by the research team and selected invited speakers.. The workshop briefs participants on the nature of the study, and participants take part in small group discussions on the strengths and needs of their services in responding to alcohol issues. Brief interactive training sessions cover screening, brief intervention, home detox (withdrawal management), relapse prevention medicines, supporting families and supporting communities in responding to alcohol.
3. Onsite training is provided at one site for each health service, and all service staff are invited to attend. Training is provided by Prof Kate Conigrave (Addiction Medicine specialist) and by an Aboriginal staff member with clinical experience (Ms Kristie Harrison, a Wiradjuri woman with a background in alcohol and other drugs work, and youth work for the early support phase). The training includes core elements: screening, brief intervention, home detox, relapse prevention medicines, working with family and working with communities. Training is interactive. ITs duration and delivery is tailored to local needs and staff availability. Up to two days training is offered per service.
4. Support with refining practice software to facilitate screening, if needed
5. Provision of one-off funding ($9000 for 'early support' ['intervention'] services) for resources to support their work with alcohol. Services are provided with a list of potential resources (e.g. visual aids to brief intervention, breathalysers), but are also able to suggest their own resources. Resources must have prior approval from the Principal Investigator (KC)
6. Feedback of routinely collected clinical data every two months - AUDIT-C screening rates and results, rate of provision of brief intervention, counselling, and relapse prevention medicines for alcohol. The feedback is provided as a visual and easy-to-read pdf document, so that is accessible to community boards as well as to staff. This is emailed to service champions during their support phase
7. Phone conferences for champions every two months - to support sharing of expertise between services. The teleconferences last about 45 minutes and are chaired by the research staff (KC and Krisitie Harrison). These occur for two years during the support phase. The teleconferences focus on the service champions reporting back on what is working well in their service with regard to improving screening and response to alcohol, and what are the challenges. Services are split into two groups according to remoteness for the teleconferences, to increase the opportunity for interaction.
8. Password-protected website and online forum to share resources and ideas with other services in the 'support' phase. Resources are posted by the researchers; in addition service staff have the option for online 'chat' with each other or with the researchers on a discussion board. There is no required use of this discussion board.
Support is provided over one year actively, and one year in maintenance mode
Adherence to the protocol is monitored by a spreadsheet: on this, research staff record the date that each element of support is provided to each study site. In addition, attendance is recorded for second monthly teleconferences, and for all training sessions.

Other interventions
Comparator / control treatment
Wait-list control. The control group will receive the intervention 2-3 years after the 'intervention' (or 'early support') group. All elements are the same, except that wait-list control services receive a smaller amount of funds ($3500) for resources during their support phase,. This is because resources and training are expected to be more fully developed by the time their support phase starts.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The services were divided into three tiers according to remoteness, and each service was allocated a code. A statistician based at a separate site (A/Prof Tim Dobbins), and who had not been involved in recruitment or determining eligibility, conducted the randomisation by computer. The randomised codes were then returned to the principal investigator (KC), who matched the matched the codes to service names to discover the allocation of services..
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation was achieved using a randomisation table created by computer software (i.e. computerised sequence generation)
Randomisation was conducted within three tiers of service remoteness.

Intervention assignment
Other
Other design features
The study design is intervention compared to wait-control. The wait control services receive no intervention initially. Then, at the end of the 'early support' phase (two years after the early support services start receiving the intervention), the wait-control services receive a nearly identical set of supports. The only difference is that they receive a smaller sum of money for resources ($3500). This is in acknowledgement of the fact that early support services will have needed to spend more time developing resources or approaches which can then be adopted by the late support services.
The early support services continue receiving data feedback during the late support phase, but no other supports.
During the testing of the interventions, staff of services in the 'intervention' arm are not told which services are participating in the wait-control arm, and vice-versa.
During the wait-control phase, all services become aware of other services involved in the study, to maximise sharing of experiences and skills.

Efficacy
Statistical methods / analysis
This dataset is hierarchically clustered. Observations are nested under client IDs which are nested under services. To account for the non-independence of observations, the results will be analysed with multi-level modelling.
As further power was required to detect an increase in treatment provision, than was required for increase in screening rate, power analysis considered treatment provision. The power analysis concluded that we would need to recruit at least 10 services per arm in order to detect an increase in treatment provision of 13% (80% power and 2-sided significance of 0.05).
The power analysis was performed with the following assumptions:
1. Eligible services see at least 1000 clients per year.
2. Approximately 60% of clients are likely to be over 16 years or older
3. Approximately 57% of clients are likely to have been screened for alcohol use within 12 months
4. the Intracluster Correlation Coefficient (ICC) for services will be approximately 0.04
