NCT03590041

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Diabetes Distress - Change in Patient Reported Outcomes (PROs)

    Comparison of change in patient-reported outcomes around diabetes distress for patients in either SMA group. Measured by the Diabetes Distress Scale (DDS-17). The DDS-17 measures the worries, concerns and fears among individuals with diabetes over time as they struggle with managing diabetes. The DDS is a 17-item self-report instrument. Each of the 17 items is rated on a 6-point scale from (1) "not a problem" to (6) "a very significant problem." The scale yields an overall distress score based on the average responses for all items. Average score of \< 2.0 = reflects little or no distress Average score between 2.0 and 2.9 = reflects moderate distress Average score \> 3.0 = reflects high distress A total score \> 2.0 (moderate distress) is considered clinically significant

    At end of 6 group visits (time differs by practice, up to 6 months)

Secondary Outcomes (1)

  • Change in Patient HbA1c

    At end of 6 group visits (time differs by practice, up to 6 months)

Study Arms (2)

Standardized SMA

ACTIVE COMPARATOR

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.

Behavioral: Standardized SMA

Patient-driven SMA

ACTIVE COMPARATOR

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.

Behavioral: Patient-driven SMA

Interventions

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.

Standardized SMA

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.

Intervention Model
PARALLEL
Model Details: 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."
