Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Stepping Up program involves two elements that address key factors that are important and influential in the way insulin is initiated and titrated in general practice:
a. Supportive education for GP and Practice Nurse (PN) that addresses inter-professional culture and clarifies roles particularly in enhanced role for PN
b. Practice systems change that is congruent with work practices of GP and PN and needs of patients to facilitate timely introduction and titration of insulin glargine and glulisine
The Stepping Up program training will be delivered by the study team during practice visit. The 1-2 hour training session covers evidence around insulin initiation, common barriers and how to deal with them, motivational interviewing and goal setting strategies, and hands on familiarisation with insulin delivery systems and insulin titration tools. Case studies derived from general practices patients are used as the basis of the training. Referrals to an endocrinologist, diabetes educators or other health professionals will be part of management options for GPs managing study patients.
GP and PN will be supported by Study Diabetes Nurse Educator (DNE) as required during 12-month follow-up period via practice visits, telephone and emails to individualise and embed the model of care to their in-practice systems.

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)
General practices that employ a practice nurse will be recruited from the University of Melbourne database, the VicREN practice based Research Network and Victorian Medicare Local databases. The study will also be promoted through professional organisations such as RACGP and APNA. Practices will also be recruited using a snowballing method from key clinicians identified in the field.
General practices that express an interest to take part will be asked to obtain a comprehensive list of eligible patients. Practices will use a range of search methods including their own electronic medical records database, the PEN clinical data extraction tool, or a list of HbA1c results from their local pathology providers. The study team will assist GP and PN to screen their patients.
Each practice will be allocated a practice ID once signed consents (at least one from GP and one from PN) are received by the research team and the practice has identified one or more eligible patients. The unit of randomisation is the general practice. Randomisation will occur prior to patient baseline assessment.

Patient recruitment involves:
1. An invitation pack from the Practice inviting eligible patients to participate and
2. follow-up call(s) from the PN and/or GP.
Patients who agree to participate will also be asked to sign the consent form and return it with the baseline demographic questionnaire in a reply paid envelope. They will be asked to attend Melbourne Pathology to have HbA1c, lipids, U&E and spot urine albumin:creatinine ratio tests.
Patients who have HbA1c>=7.5% will be eligible to participate and will be mailed a baseline survey.
Patient identification and recruitment can be repeated at 3 month intervals allowing patients to enter the study sequentially and ensuring the initiation of insulin and patient management is easily embedded within routine clinical work. Each practice will ideally recruit four to five patients to the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be stratified by:
1. practice size (<=2 EFT GPs vs >2 EFT GPs) ,
2. practice type (Community Health Centres vs private/corporate); and
3. participation in the Australian Primary Care Collaboratives program (www.apcc.org.au).
Randomisation will be undertaken by a statistician independent of the research team. The statistician the will be blinded to practice stratification characteristics and random allocation. The Study Coordinator will assign codes specific to each practice stratification characteristics and group allocation. The statistician will generate a computerized random number in random block allocation. Practices will be randomised after consenting, prior to patient baseline data collection. The Study Coordinator will email stratification codes of consenting practice to the statistician who will inform the study team of practice random allocation codes by email within 24-48 hours. Stratification in random block randomisation method is required to minimize imbalances between study groups.
The research team will inform practices of their random allocation by phone call, fax or mail. Following randomisation, the research team will assist practices to identify and recruit more patients.
