AAs have twice the rate of DM as Whites, and worse glycemic control, less optimal medication regimens, and less trust in the medical system. These disparities contribute to why AAs with DM are more likely to go blind, lose limbs, require dialysis, develop dementia, and die than Whites. These disparities, in turn, reflect racial differences in education, income, health literacy, cultural beliefs, experiences of discrimination, and social adversity, which can lead to: 1) poor glycemic control; 2) suboptimal medication use; and 3) mistrust in medical care. DM I-TEAM addresses these 3 factors, which often precipitate ED and hospital care, using a culturally relevant, multidisciplinary team treatment approach to reduce the need for high acuity medical care, and equip underserved AAs with DM with the knowledge and skill to gain the benefits of high quality medical care that is otherwise available to everyone. Our approach applies currently available treatment elements in a culturally-relevant way to create a more equitable health landscape. Our immediate goal is to engage a high-risk population in treatment that can be trusted; that recognizes the realities of their lives (e.g., financial insecurity); that improves the quality of the medication they take, and that builds their self-efficacy to manage DM. The intermediate goal is to prevent untoward medical events that necessitate ED or hospital care. The long-term goal is to reverse the pernicious racial disparities that now characterize healthcare in the U.S. DM I-TEAM can achieve these goals by getting the right care to the right patient at the right time. DM I-TEAM is the right care because its leverages existing resources in a new way to improve health outcomes in AAs with DM. AAs with DM are the right patients because many have poorly controlled DM, take suboptimal medications, and face treatment barriers, often social in nature. Now is the right time, as the population becomes more racially diverse, healthcare costs increase, and demand for safety, quality, and value intensify. In these ways DM I-TEAM is right for American healthcare, bringing us closer to Healthy People 2020's twin goals of reducing the personal and societal costs of DM, and achieving health equity for all.

DM I-TEAM takes a dynamic team approach to diabetes management whereby the primary care physician, the study pharmacist, the diabetes educator, and the CHW collaborate to build patient trust, encourage diabetes self-management, and optimize medication regimens. Each member of the team plays a pivotal role in identifying important information that prevents effective diabetes management, and then works together to provide multi-layered support to patients. The roles of each team member are as follows:

CHW: The CHW extends clinic-based care into participants' homes to strengthen patient/provider relationships, customize diabetes education, and develop tailored treatment plans. The CHW facilitates telemedicine visits with the PCP and diabetes educator to build trust in the health care system by increasing participants' access to their care team. The quality and content of these visits is enhanced by CHW-provided information about the participant's life situation (e.g., family circumstances, barriers to optimal diabetes self-management, home environment), and current self-management practices and beliefs. There will be 6 90 minute in-home CHW sessions within 3 months of randomization (telemedicine sessions will occur during 3 of these visits). Booster sessions will occur 5, 7, and 11 months after randomization. During these visits, the CHW will (1) reinforce the diabetes treatment plan articulated by the PCP, (2) gather information regarding barriers to diabetes self-management behaviors and communicate them to the team; (3) inform the team of the participant's health-related questions/issues; (4) provide culturally-relevant diabetes education using appropriate educational materials; (5) work with the participant to formulate and execute diabetes Action Plans using the principles of Behavioral Activation (BA); and (6) communicate the participant's progress with their Action Plans to the team. BA is a behavioral technique based on reinforcement theory that is used to help people overcome avoidant tendencies through goal setting, activity scheduling, and graded task assignment. BA was originally developed to treat depression. Our research has demonstrated that BA can successfully facilitate diabetes self-management. The DM I-TEAM treatment manual (which is already developed but will be refined during the study start-up phase) describes each session in detail, and includes scripts and didactics for the CHW interventionist. The manual is not included in this grant submission due to space limitations. At each session, the CHW educates participants to contact the ED (either by phone or by patient portal) prior to presenting for services. Participants are given "emergency kits" that contain glucometers and related supplies and glucose tablets. The ED physician may recommend that participant's test their glucose and treat hypoglycemia prior to or instead of reporting to the ED.

PCP: The PCP provides diabetes care as per standard practice, but care is supplemented with input from the pharmacist and the CHW, and with telemedicine visits. The PCP optimizes medication regimens based on pharmacist recommendations. As the course of treatment progresses, the PCP reinforces Action Plans with the participant during clinic visits.

Pharmacist: With information gathered by the CHW and from the participant's electronic medical records (EMR), the pharmacist performs a comprehensive evaluation of the participant's medications to identify medications that are contraindicated in older patients, are not being taken as prescribed, are being taken incorrectly, are improperly dosed, or may be causing undesirable side effects. Based on her assessment, the pharmacist may recommend that the PCP modify the current medication regimen.

Diabetes Educator: The diabetes educator provides telemedicine visits to supplement diabetes education provided by the CHW, answer participants' questions, and reinforce medication adherence.
