The 2003 Canadian Diabetes Association clinical practice guidelines recommend early and sustained glycemic control targeting an A1C < 7%. The guideline target however is not achieved in 50% of patients with type 2 diabetes in the Canadian family practice setting. Family physicians are not comfortable initiating and managing insulin for their patients the DICE study5 found that only 12% of the 2473 patients audited were prescribed insulin; 6% insulin alone and 6% in combination. Harris et. al. found 20% of patients prescribed insulin, 15% insulin alone and 5% in combination. A strategy to increase physicians' knowledge, skill and comfort with insulin prescription is needed to better achieve glycemic control for patients with type 2 diabetes in Canada.
Purpose - The purpose of AIM@GP is to increase family physicians clinical experience and comfort with insulin prescription and better achieve glycemic control for patients with type 2 diabetes in Canada.
Primary Objective - To determine the effectiveness of a Basal Insulin Initiation strategy on family physician insulin prescribing behaviour. The strategy, using a multifaceted behaviour facilitation approach, includes diabetes specialist consultation support, and community pharmacy insulin initiation support.
Study Design - The study design is a stratified, parallel group, randomized control effectiveness study. All physicians will attend an insulin education workshop where they will receive a Diabetes Practice Profile and randomly allocated in a 1:1 manner into the intervention or control group.

This multifaceted intervention consists of (1) Diabetes Specialist Consultation Support which entails specialists and educators providing consultation for insulin initiation and titration for the 12 months following the Workshop. Support will consist of prearranged and scheduled communications to review and advise for the first 2 months and will continue on an ad hoc basis for the remaining 10 months, with communication initiated by the physician (2)Community Pharmacy Insulin Initiation consists of trained community pharmacists providing patient education insulin initiation. Education will consist of one individual teaching session, one hour in duration, to review the insulin prescription protocol, insulin injection method, management of hypoglycemia, and self-monitoring of blood glucose.

|No Intervention: Usual Practice|
- Insulin Prescription Rate - the number of insulin-eligible patients per 12 months who are prescribed insulin in each FP practice [ Time Frame: 12 months ]
- mean A1C of insulin-eligible patient per family physician post-Workshop [ Time Frame: 14 months ]
- mean FBG of insulin-eligible patient per family physician post-Workshop [ Time Frame: 14 months ]
- Proportion of insulin-eligible patients with intensification of diabetes management (increase dose of OAD or insulin, OAD score, the addition of insulin) per FP post - Workshop [ Time Frame: 12 months ]
- proportion of patients at target (≤ 7.0%) at time of the Workshop and post - Workshop [ Time Frame: 14 months ]
- proportion of patients at target (≤ 6.5%) at time of the Workshop and post - Workshop [ Time Frame: 14 months ]
- change in "Insulin Prescription Rate" from baseline prior to the Workshop to 12 months post - Workshop [ Time Frame: 12 months ]
