Measure
Low Intensity
All participants randomized to this arm will receive quarterly educational mailings and limited telephonic outreach delivered by a pharmacist focused on insulin adherence and glycemic control. Low intensity: Low intensity telepharmacy outreach
Moderate Intensity
Participants will receive all intervention components as in the low-intensity arm but will receive more frequent pharmacist follow-up and the option of enrolling in a text-messaging program. The pharmacist will also provide limited follow-up with the participant's provider. Only 60% of participants randomized will be targeted to receive the intervention based on adherence risk score. Moderate intensity: Moderate intensity telepharmacy outreach
High Intensity
Participants will receive all intervention components as in the moderate-intensity arm but will receive more frequent pharmacist follow-up. The pharmacist will also provide more follow-up with the participant's provider and/or pharmacist. Only 40% of participants randomized will be targeted to receive the intervention based on adherence risk score and baseline disease control. High intensity: High intensity telepharmacy outreach
