Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Study will recruit general practices within participating Divisions of General Practice. Participating practices will be randomly allocated to intervention group (30 practices) which will receive the intervention immediately following randomisation. Study staff collecting data will be blinded. Method: Six-month intervention driven by the practice with assistance from a facilitator (from the research team). The intervention will focus on establishing practice systems and defining roles and procedures for non-GP staff for the management of patients with type II diabetes or ischaemic heart disease, or hypertension to ensure: evidence based care is offered; patients return for follow-up; adequate access to appointments and length of consultations or group sessions is available; regular and comprehensive assessment and monitoring is carried out; multidisciplinary care needs are identified and plans to address them are implemented; access to structured patient education sessions and patient education resources is available; appropriate referral is made; financial stability of teamwork is optimised through use of Chronic Disease Management (CDM) Medicare items. Each practice in the intervention group will receive the core intervention, consisting of education sessions, practice visits and ongoing support, with additional customisation for each practice's specific circumstances. Located in the practice, the intervention will be conducted through and with the support of the division, who will support practices beyond the intervention period to maintain the effect of the intervention. At the completion of the study, the intervention will be offered to the control practices.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment will be achieved by Patient selection, patient consent and baseline data collection will occur before randomisation. Using a centralised randomisation scheme where a University of NSW statistician not involved in the study (not linked to practice or patient recruitment, or staff recruitment) and who is blinded to the identity of the participating practices will generate random numbers using computer generated random numbers. The outcome of the random allocation will be kept in sealed envelopes. Project staff who collect data are different from those who deliver the intervention. Data collection officers will be unaware of random practice allocation. The intervention research assistants will not be informed of the practices in the intervention group until they start delivering the intervention.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block design will be used to randomise participating practices into intervention and control groups. Practices within each division of general practice will constitute one block. In each block, practices will be allocated to intervention or control groups using computer generated random numbers.
