Detailed Description
Anticipated Impacts on Veteran's Healthcare: Weight management is an important focus of VA as evidenced by its VA/DoD Clinical Practice Guideline and MOVE! program targeting overweight/obesity. VA is also committed to using group visits to increase the efficiency and effectiveness of health care delivery. The investigators aim to test a novel intervention that combines intensive weight and diabetes management using the SMA platform. This research addresses important missions to VA because diabetes is more prevalent in Veterans than in the general population, and because weight management is more challenging and complex in patients with diabetes. Project Background: SMAs involve groups of patients who share a common chronic condition and meet over time to receive education, self-management enhancement, and medication management to improve clinical outcomes. A systematic review by VA found that SMAs modestly improve glycemia in patients with diabetes. Although these SMA programs sometimes included diet and physical activity counseling, weight management was not a primary goal, and weight typically was not reduced. Instead, medication intensification was the primary strategy for improving glycemia, and this strategy can lead to weight gain.
For overweight patients with diabetes, weight loss is first-line therapy because it can improve glycemic control and because excess weight leads to poorer outcomes. Moreover, many antiglycemic medications cause weight gain and hypoglycemic events, which may counteract the potential macrovascular benefits of glycemic control. Dietary interventions, however, can lower weight and improve glycemic control while reducing antiglycemic medication needs and, therefore, subsequent risk for hypoglycemic episodes.
In prior research, the investigators induced weight loss and improved glycemic control while decreasing antiglycemic medications. A combination of an intensive weight management program with the diabetes management offered in SMAs has potential to further improve diabetes outcomes, reduce complications, decrease costs and increase health-related quality of life. Such a combined intervention is ideal for patients with diabetes because of their unique dietary considerations, and their need for careful glycemic and medication management during weight loss. Project Objectives: The investigators will examine whether an intensive, group-based weight management program followed by an SMA intervention (WM/SMA arm) is comparably effective (non-inferior) to the SMA intervention alone for improving glycemic control while using less antiglycemic medication and resulting in fewer hypoglycemic events and lower healthcare costs. Project Methods: 308 overweight VA outpatients with uncontrolled (hemoglobin A1c 8.0% or 7.5% or greater for those under 50) type 2 diabetes will participate in this RCT. Similar to prior SMAs, the SMA visits will occur every 4 weeks for 16 weeks and then every 8 weeks for 32 weeks for a total of 9 visits. Sessions will be led by a physician and trained interventionists, and will include educational topics related to diabetes management (including diet and physical activity), self-management training, and medication adjustment. Similar to the investigators' prior weight management trials, the WM/SMA group will meet every 2 weeks for 16 weeks and then every 8 weeks for 32 weeks for a total of 13 visits. The weight management program will focus on a low carbohydrate dietary pattern because of its potential to lower glycemia, leading to reduced antiglycemic medication needs. After 16 weeks, meeting content will shift to the SMA intervention content but weight management will continue to be addressed at the meetings. The primary outcome is glycemic control assessed by hemoglobin A1c assessed at baseline and at 16, 32, and 48 weeks. Secondary outcomes include hypoglycemic events, changes in the antiglycemic medication regimen as assessed by a summary score, weight and healthcare costs. Diabetes-specific health-related quality of life and medication adherence will also be assessed.

Hypoglycemic Events
Time Frame: through 48 weeks
|
All episodes of hypoglycemia will be recorded by participants on provided standard log forms, noting the date, time, duration, symptoms, treatment received, and concurrent blood glucose.
Participants will additionally be asked if they received medical attention for hypoglycemia, and the details if so, since the last assessment.
Only one episode will be counted per 24 hours.
Serious episodes, defined as <50 mg/dL or 50-69 mg/dL and requiring assistance, will supersede minor episodes in this case.
|
through 48 weeks
|
Medication Effect Score
Time Frame: 48 weeks
|
Antiglycemic medications, dosages, and schedules will be assessed carefully with the participant and updated at each visit.
A Medication Effect Score (MES), based on the potencies and dosages of the medications in a patient's regimen, was devised to reflect the overall intensity of antiglycemic medication.
The MES is calculated as the percentage taken of the maximum dose multiplied by the expected hemoglobin A1c lowering effect for each of a participant's medications, which are then summed.
Its range is 0 to infinite, with higher scores meaning higher diabetes medication requirement.
