Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the investigators will compare the effectiveness of patient-driven diabetes Shared Medical Appointments (SMAs) to standardized diabetes SMAs. The curriculum to be used is Targeted Training for Illness Management (TTIM), a 6-session modular group intervention for chronic illness self-management, and has been tested in diabetes. The standardized group visit model will consist of diabetes SMAs with the full TTIM 6-session curriculum, led by a health educator.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Type II Diabetes is a prevalent chronic disease with poor outcomes, and requires daily self-care, including blood glucose monitoring, following a diabetes-friendly diet, engaging in regular physical activity, and medication adherence. Patients with diabetes benefit from comprehensive diabetes self-management education (DSME) and self-management support (SMS) in primary care. Shared medical appointments (SMAs) are one way to efficiently and effectively provide DSME and SMS. SMAs can have a variety of different features, but it is not known which features are most effective for which types of patients. Patients and other stakeholders engaged in planning this study proposed a model with "diabetes' veterans" (i.e., diabetes peer mentors) who co-facilitating group visits with a variety of diabetes care professionals, and then working one-on-one with patients to help apply what they learned. The group visit curriculum should include topics on physical activity, healthy eating, taking medication, acceptance and coping, and social support, and each cohort of patients should get to select topics most relevant to them. The practice stakeholders want to do more comprehensive group visit models, but need to know the extent to which SMA participation and patient-centered outcomes are improved compared to the more common standardized approaches they tend to use now.

In this study, the investigators will compare the effectiveness of patient-driven diabetes SMAs to standardized diabetes SMAs. The curriculum to be used is Targeted Training for Illness Management (TTIM), a 6-session modular group intervention for chronic illness self-management, and has been tested in diabetes. The standardized group visit model will consist of diabetes SMAs with the full TTIM 6-session curriculum, led by a health educator. For the patient-driven SMAs, patients choose the topics and the order of sessions from the TTIM curriculum, which is delivered collaboratively by the multidisciplinary care team consisting of several professional providers (health educator, medical provider, and behavioral health provider) and a lay worker (diabetes peer mentor). The primary patient-centered outcome, selected by patient stakeholders, is diabetes distress. Secondary outcomes include autonomy support and diabetes self-management behaviors, clinical outcomes (hemoglobin A1c, blood pressure, and body mass index), patient reach and engagement, and practice-level value and sustainability. Patient, caregiver, practice, health plans, and research stakeholders will be engaged in all aspects of the research. Patients and other stakeholders will inform the process of implementation of patient-driven and standardized SMAs, help finalize the research protocol (including data collection and recruitment), and contribute to interpretation of findings and dissemination of findings, including messages that help other patients make decisions about whether or not to participate in SMAs.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The two interventions are based in the Chronic Care Model, which emphasizes whole person care, addressing physical, mental health and psychosocial needs. The conceptual model underlying patient-driven diabetes Shared Medical Appointments is based on self-determination theory (SDT) and principles of whole person care. According to SDT, human motivation and behavior are a function of the social environment and the extent to which that environment supports basic psychological needs shown to enhance "self-determined motivation."

Primary Study Purpose

HEALTH_SERVICES_RESEARCH

Blinding Strategy

NONE

Blinding is not possible with the study design. Patients will not know that there is a difference in SMAs

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standardized SMA

The standardized SMA model includes the same TTIM curriculum as in the patient-driven model, but it is delivered in a standardized way (order of and time spent on topics are set) across all participating practices.

Group Type ACTIVE_COMPARATOR

Standardized SMA

Intervention Type BEHAVIORAL

Patients receiving the Standardized SMA intervention will be part of group visits that cover a modified TTIM 6-session curriculum, delivered only by health educators. The Standardized SMA approach will be uniformly administered at each practice. Topics will be covered in a predetermined order and patients will not have a say in terms of what content they wish to cover. Patients receive the Standardized SMA approach if their practice is randomly assigned to the Standardized SMA arm. Practices are cluster-randomized to deliver a standardized or patient-driven group visit model.

Patient-driven SMA

In the patient-driven SMA model, patients receive the same TTIM curriculum, but patients at each practice are able to set the order of the curriculum and dictate how long to spend on each topic.

Group Type ACTIVE_COMPARATOR

Patient-driven SMA

Intervention Type BEHAVIORAL

Patients receiving the Patient-driven SMA intervention will be part of group visits that cover a modified TTIM 6-session curriculum, but patients are in control of time spent and order of the topics. The Patient-driven SMA will be delivered by a multidisciplinary team consisting of a Health Educator, medical provider, Behavioral Health Professional, and a diabetes peer mentor. Patient-driven SMAs may be delivered differently at each practice, as patients choose the topics that are most important to spend the most time on. All topics will be covered, but the order and time spent is up to the group. Patients receive the Patient-driven SMA approach if their practice is randomly assigned to that arm. Practices are cluster-randomized to deliver a standardized or patient-driven SMA model.
