Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Nutrition, lifestyle support, drug management, physical activity support to participants, workshops and focus groups for participants, care planning with each participant. The intervention will involve treatment intensification including with insulin, nutrition coaching with families, and upskilling of health workers in clinical management. The frequency and duration of these sessions will be tailored to the needs of the community and the participants. This will include engaging with families to discuss nutrition, lifestyle support, smoking cessation and physical exercise, self-monitoring of conditions, and appropriate drug management, and using local resources to support effective client self-management. The unit of intervention is the COMMUNITY, via a designated specialist health worker. This means that out of the 12 participating communities, 6 communities will be randomly selected to undertake the intervention in the first 2 years. The remaining 6 communities (the control communities) will not take part in the intervention. Control communities will participate in the intervention in year 3 of the study with one IHW FTE will be recruited for each intervention site, who is eligible at HW Level 004. An Indigenous clinical support team (ICST) will train and mentor community-based IHWs (and the rest of the PHC team) to deliver intensive management for 5 common chronic conditions, with clear clinical and service goals.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Enrolment is by the health service from the diabetes register. Randomisation is by community. Allocation is concealed because clusters are randomly selected to the intervention group after enrolment of participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation. All 12 community (cluster) names are placed into a hat, and the first 6 names removed from the hat receive the intervention.
Masking / blinding
Open (masking not used)

Summary
Brief summary
The life expectancy gap for Indigenous people in Australia is 13 years and most of this gap is due to preventable chronic disease (diabetes, heart, lung and renal problems) in adults. Once people have these conditions, many complications can be prevented with good primary-level chronic care. This project aims to introduce and evaluate a new strategy for integrated community-based, intensive chronic condition management in rural and remote Indigenous primary care services: Diabetes, hypertension, coronary heart disease (CHD), renal disease and chronic obstructive pulmonary disease (COPD).

Proposed strategy: An intervention in 3 phases over 5 years:

1. A trial of intensive locally delivered chronic care in 6 out of 12 participating sites in FNQ with clear clinical and quality-of-life outcomes;
2. Review of lessons learned in the first phase trial, modified as necessary to reflect findings, a discussion about generalisability to the “control” sites in the trial, with an implementation plan and the development of a curriculum package for the program and;
3. In collaboration with the trial partners(QH, Apunipima CYHC and local AMS where relevant), a more general system rollout of lessons learned, with potential regional implications of a patient-centred service delivery model, including workforce and funding applications.
