INtegrating DEPrEssioN and Diabetes treatmENT (INDEPENDENT) Study
In Brief
A clinical study evaluating Patient Education and Behavioral Activation, Supporting Self-Care (care coordinators), and 3 other interventions for Diabetes and 2 related conditions. Completed, enrolled 404 participants across 4 sites.
Detailed Summary
To provide better care and preventive services for people with both depression and diabetes, the investigators propose to develop and test whether interventions to reduce depressive symptoms can be integrated into routine diabetes clinics in India. The investigators will gather feedback from patients in India through focus group discussions and individual interviews so they can culturally-adapt a model of combined depression and diabetes care. The investigators will then evaluate the effectiveness and costs of this care model in a trial at four diabetes clinics in India. It is expected that results from this study can guide how to incorporate mental health care into routine diabetes clinics in low-resource settings.

Interventions
To stimulate and motivate sustained, effective self-care, patient education materials and behavioral activation techniques that are adapted for the Indian population will be used by care coordinators. Behavioral activation strategies are brief, structured psychological interventions that are based on extensive theoretical and clinical literature, can be delivered by non-specialist providers, can be combined with antidepressant medications, and emphasize reinforcing behaviors to produce improvements in thoughts, mood, and quality of life.
Care coordinators will: (a) meet with intervention arm patients and collaboratively set treatment goals; (b) provide verbal education regarding diabetes and depression self-care ;(c) will use motivational interviewing and self-efficacy enhancement strategies to promote monitoring of depressive symptoms, glucose, BP; (d) will proactively follow-up to externally monitor depression symptoms and CVD indicators; (e) will enter updated patient indicators into decision-support electronic health record and utilize software outputs to prioritize patients for review; (g) will convene case review meetings with supervising physicians; and (h) will communicate physician-recommended treatment changes to patients and their routine providers.
Senior psychiatrist and endocrinologist/diabetologist will be involved in weekly offline case review meetings with care coordinators. Case review meetings will be structured: the decision-support electronic health record will help prioritize cases that are new (within 3 weeks of randomization); have moderate/severe depression symptoms (based on Patient Health Questionnaire (PHQ)-9) ≥6 weeks after most recent treatment changes, or continued poor HbA1c, home glucose, BP, or LDL-c control in past 4 weeks; or have not been reviewed for 3 months. Based on patient indicators and current therapies, physicians will recommend treatment changes (initiation, increases, or simplification of medication regimens) which will be communicated by care coordinators to patients and their usual care providers.
The decision-support electronic health record will store patient indicators entered by the Nurse Case Managers (NCM) and provide diabetes and depression care prompts based on an evidence-based treatment algorithm developed from recommended guidelines for control of diabetes and depression, Indian formularies, and TeamCare investigators. The decision-supported electronic health record (DS-EHR) will prioritize patients (new; poorly-controlled; or well-controlled but not reviewed ≥3 months) for case review meetings and promote accountability (physicians must justify rejecting electronic care prompts).
Participants randomized to the control arm will receive the existing standard care and treatment for their diabetes that is provided routinely at each Clinic Site and their care provider will be notified regarding their depressive symptoms. The physicians treating the control arm will also be provided with trainings regarding identification and care for people with depression. The control participants will have no contact with care coordinators and will only be contacted at 6-monthly intervals for assessment by the blinded outcomes assessor.
