Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a facilitated program of knowledge translation strategies that comprises skills development, networking, personal contact and other related activities that will strengthen the organisational context to enable use of research evidence.

Councils in the intervention arm will receive a facilitated program in addition to access to evidence summaries. Councils in the comparison arm will receive evidence summaries alone.

The duration of the intervention will be 2 years.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All 45 councils who completed a pre-trial baseline survey will be invited to participate in the trial by the program coordinator responsible for program implementation. Each intervention council will nominate a number of staff to particpate in the intervention. Stratified block randomisation will be used to randomly allocate councils to intervention or comparison groups. Strata will be defined by tertile of council annual budget. Once participation has been agreed and a memorandum of understanding has been signed, the program coordinator will email the trial manager with the name and annual budget of the council. The trial manager will then email the trial statistician with the stratum (but not name) of the council. The statistician will allocate the council (blind to its identity) to intervention or control on the basis of a randomisation sequence generated and held by the trial statistician and concealed to all other parties. The trial manager will log the group allocation on the trial database and inform the program coordinator.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A seperate sequence will be generated for each of the 3 strata using a predetermined block size. Computer generated random numbers will be used to determine each sequence using the permutations satisfying the criteria of equal allocation to group within the predetermined block size.
Masking / blinding
Blinded (masking used)
