Intervention/exposure

Interventional
Description of intervention(s) / exposure
Intervention arm:
Participating staff from diabetes centres randomised to the intervention arm will receive a targeted theory-based intervention designed to address identified, modifiable barriers to implementing recommendations from audit feedback provided by ANDA, in addition to the standard audit feedback report. Design of the intervention is underpinned by a formal qualitative study to elicit current quality improvement practices and barriers to implementation of feedback. This qualitative study sought opinions from clinical staff regarding the acceptability and utility of the audit feedback currently provided, via semi-structured interviews. This study has informed redevelopment of the feedback provided to participating sites and development of the cointerventions in this trial
The intervention involves a reformatted version of the site report currently provided, along with a PowerPoint template for site use. This will be delivered electronically to participants by the ANDA research team at one point in time.
Cointerventions will include a Quality Improvement (QI) webinar, 'change champion' videos, instructional videos and peer led forums. These will all be delivered via the National Association for Diabetes Centres (NADC) website, prior to receiving the new feedback report and PowerPoint presentation and will remain accessible to the intervention group. Access to these resources will be password protected to prevent contamination of the control group.
Centres participating in the intervention arm will be expected to complete a minimum of 3 activities from the educational and peer support resources, including:
1. Attendance at the QI webinar – this will be hosted initially in the evening, with a replay with live question and answer session during a lunch hour, to facilitate maximum uptake
2. Viewing of at least one ‘clinical change champion’ video
3. Participation in at least one peer led forum
We anticipate that the interventions will be delivered during a six month period from August 2020 to January 2021. we anticipate that the webinar will be delivered in the first 4 weeks of the intervention period (to allow for the initial live presentation and subsequent replay) and that the remaining activities ('clinical change champion' video and peer forums) can be completed anytime in the first 3 months of the intervention period. Participants will continue to have access to these resources until follow-up data is collected in February of 2021.

Patient data: The study will not recruit patient participants. Rather, patient data for pre-determined fields will be harnessed from existing routinely collected and de-identified (coded) data reported as part of ANDA annual audit. We are not collecting any additional data directly from patients.

Eligibility
Key inclusion criteria
Diabetes centres: Diabetes centres registered with the National Association of Diabetes Centres will be eligible for inclusion in the trial if the following criteria are met: (i) at least one representative of the practice (the designated contact person for ANDA) provides written informed consent; (ii) the practice participates in ANDA in 2021 (irrespective of whether they have or have not participated in previous years).
The designated ANDA contact person for each participating site are the participants in this study, as they receive and act on the feedback provided. They must be over 18 years old and employed by the relevant diabetes centres. As the diabetes centres have a range of clinical staff and administrative staff involved in ANDA, there are no other restrictions regarding these staff.



We will harness deidentified existing ANDA data relating to type 1 or type 2 diabetes mellitus in people aged 18 years and over.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
There are no additional exclusion criteria related to diabetes centres.
We will not harness ANDA data relating to people with Gestational Diabetes Mellitus (GDM), or diabetes of unknown type.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A stratified block randomisation will be employed with stratification by location (metropolitan or rural) and type of centre (tertiary, secondary or primary).

Primary outcomes
Differences between the experimental and control groups will be analysed by intention-to-treat approach. For the first co-primary outcome of difference in HbA1c, we will use the Linear Mixed Effects model to compare the between-group difference in mean HbA1c at 6 months after delivery of the intervention while adjusting for clustering of patients with site by including a centre random intercept. Appropriate transformations of the data will be undertaken in the event of departure from normality. Only if the first co-primary outcome is statistically significant at a two-sided level of significance of <0.05, we will test the second co-primary of acceptability and utility of interventions for superiority using the Chi-squared or Fisher’s Exact test as appropriate. This will preserve the overall type 1 error at <0.05.
Secondary outcomes
Other secondary clinical endpoints (e.g., mean LDL-Ch) and exploratory outcomes (e.g. mean HbA1c at 18 months) will similarly be analysed using the Linear Mixed Effects model.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
Sharing of diabetes centre data may inadvertently identify participants (e.g. if only one centre in a given state takes part in the trial)
Given this cluster trial is harnessing data collected through an existing national audit and data is collated and de-identified (coded), it is not possible to access IPD.
