简要总结
This clinical trial will compare the effectiveness of the Healthy Outcomes through Patient Empowerment (HOPE) intervention to enhanced usual care (EUC) for diabetes and depression at 6 and 12 month follow-up. The proposed study is a randomized controlled trial enrolling 242 largely rural Veterans with uncontrolled diabetes and clinically-significant depressive symptoms. Both groups will receive screening, education, and notification of clinical findings along with follow-up in usual primary care. HOPE participants will also receive behavioral coaching telephone sessions over a six month period. Patients in the control group will be screened, and providers will be notified of high risk patients' status and need for intervention. Both groups will receive only usual primary care during the subsequent 6 month maintenance period. Study measurements using self-report questionnaires will also be collected at baseline, 6 and 12 months follow-up. The investigators will also conduct chart reviews to evaluate usual care blood tests for diabetes control. Changes in measurements from baseline will be compared between groups. This intervention will reach Veterans in rural setting where community-based primary care is needed, especially care that blends treatment strategies for physical and emotional health.
详细描述
Project Background: The co-occurrence of diabetes and depressive symptoms is highly prevalent and has dramatic consequences on the quality of life and health of affected patients. Due to the complex interrelation between these conditions, patients often experience both psychological and physiological difficulties. Furthermore, Veterans with diabetes and depressive symptoms in rural settings have limited access to care. Interventions that reach Veterans in rural / community-based primary care are needed, especially those that blend treatment strategies for physical and emotional health.
Project Objectives: Specific (Primary) Aim (1): Compare the effectiveness of the Healthy Outcomes through Patient Empowerment (HOPE) intervention to enhanced usual care (EUC) at 6 and 12 month follow-up.
Hypothesis 1a: After 6 months (active treatment phase), HOPE will produce greater improvements in diabetes control (measured by hemoglobin A1c levels) and depression (measured by PHQ-9 scores) than will EUC.
Hypothesis 1b: At 12 months (6-month active phase plus 6-month maintenance phase), HOPE participants will continue to evidence significant greater improvements in HbA1c and PHQ-9 compared with EUC participants.
Exploratory Specific Aim (2): To examine the role of moderators and mediators on intervention effectiveness Exploratory Aim 2a. To evaluate factors that mediate or moderate effectiveness at 6 and 12 months for all enrolled patients (regardless of intervention group assignment). Potential mediating and moderating variables include patient-level (clinical factors-diabetes distress and self-efficacy and sociodemographics) and facility-level factors (availability of medical and mental health services by clinical site).

入选标准
- •Veterans with comorbid diabetes and depressive symptoms receiving primary care services at VA CBOCs throughout Southeast Texas
- •as well as MEDVAMC patients living >20 miles from the hospital who face similar distance related treatment barriers
- •Participants must have:
- •a diagnosis of diabetes mellitus
- •an average HbA1c level >7.5% in the prior 6 months
- •clinically significant symptoms of depression
- •Verification of diabetes mellitus diagnoses will be based on data collected from the VA data warehouse.
- •To verify that participants meet the depression criteria, the investigators will use participant self-report of clinically significant depressive symptoms according to the PHQ-9, where a score of greater than/equal to 10 on the PHQ-9 will signify a clinically meaningful symptom burden.
排除标准
- •The investigators will exclude potential participants only for clinical factors that would render a telephone-based behavioral activation intervention inappropriate.
- •Specific exclusion criteria are:
- •lack of regular access to a telephone
- •significant cognitive impairment (three or more errors) on an established six-item screening exam
- •meeting criteria for bipolar, psychotic, or substance-abuse disorders
- •presence of uncorrected hearing or vision impairment
- •their medical chart recommends not titrating therapy due to prior history of significant hypoglycemic events
- •they live within 20 miles of the MEDVAMC.
- •Patients will be secondarily excluded if their HbA1C level falls below 7.5% at baseline assessment, or if they report suicidal ideation on the PHQ-9 at baseline assessment.
- •Patients receiving mental health services at the time of study recruitment will not be excluded.
- •All mental health treatments and health service-use characteristics will be included in study analyses as covariates.
研究组 & 干预措施
Arm 1: HOPE
The Healthy Outcomes through Patient Empowerment (HOPE) intervention group is the intervention arm which will employ behavioral health coaching telephone sessions. Tele-coaching is a theoretically grounded, structured processes guided by intervention manuals.
干预措施: Healthy Outcomes through Patient Empowerment (HOPE) (Behavioral)
Arm 2: EUC
The Enhanced Usual Care (EUC) group will serve as a concurrent control group to compare to the intervention arm of the study. Participants are screened for diabetes self-management behaviors and control and for active depressive and anxiety symptoms. Primary care providers are alerted of the patients' status and given decision support to enhance care for these uncontrolled conditions.
干预措施: Enhanced Usual Care (Behavioral)
结局指标
主要结局
Change in Hemoglobin A1C
时间窗: Hemoglobin A1C levels will be measured at baseline, 6-, and 12- months.
Measures of Hemoglobin A1C will be taken to assess average blood glucose levels throughout the study as an indicator of diabetes control. Hemoglobin A1C is a blood test taken to assess average blood glucose levels in the body. Normal range of A1C level is below 5.7. Eligible participants had an A1C of 7.5 or higher. The higher the A1C the more a person's diabetes is uncontrolled.
Change in Patient Health Questionnaires-9 During Intervention
时间窗: PHQ-9 will be assessed at baseline, 6-, and 12- months.
The Patient Health Questionnaires-9 assesses depressive symptoms during the course of the intervention. The PHQ-9 ranges in score from 0 - 27; where higher numbers represent increase levels of depression. Scores from 5 - 9 represent "minimal symptoms" of depression; 10 - 14 represent "minor depression", dysthymia, or major depression - mild; 15 - 19 represent "major depression, moderately severe"; and scores of 20 and above is considered "major depression, severe." Participants with that scored a 10 or above were eligible for the study.
