Brief summary
This trial investigates the value created by the highly innovative Fresh Food Farmacy (FFF) program at Geisinger Health. The program provides food-insecure diabetics with healthy food for their entire household: at least two meals per day, five days a week. The program also provides education on how to prepare the food, and education on healthy living including diabetes self management. The research measures the effects of the FFF program on patient health and wellbeing.
Detailed description
This is a pragmatic, prospective, randomized controlled trial of Geisinger's Fresh Food Farmacy (FFF) program as the program expands to new sites. Qualifying subjects will be randomized 1:1 to receive either early participation in the FFF program (treatment group) or later participation (control group). Approximately 500 Geisinger subjects will participate in this study with about half assigned to the treatment group and about half to the control group. The treatment group will begin the program soon after trial recruitment: the Begin Now group. The control group will begin the program after 6 months: the Begin Later group. Approximately 2000 household members will be included in the data-only portion of the research. Outcomes will include clinical measures, such as HbA1c, survey responses including self-assessed health measures, and utilization / healthy-behavior measures from EHR and paid claims data. These will be measured for subjects and their household members.
Interventions
Patients are prescribed fresh food by a dietician, fill the prescription each week at the FFF clinic, receive training on how to use the food, and training in diabetes self management.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| HbA1c | 6 months after trial enrollment | Glycated hemoglobin (HbA1c) is a measure of the average share of glucose that has been in the bloodstream over the 2-3 months preceding measurement. HbA1c is measured by performing assays on samples of the participants' blood. Units are percentages; for differences between HbA1c values, units are percentage points. An HbA1c value of 6.5% is the lower threshold for type 2 diabetes. HbA1c values are rarely above 15-20%. In the context of this study (patients with type 2 diabetes), higher scores are considered a worse outcome. |

In the context of this study, higher BMI is considered a worse outcome. |
| Total Cholesterol | 6 and 12 months after trial enrollment | Total cholesterol in mg/dL. The CDC recommends total cholesterol levels around 150 mg/dL and classifies levels of 200 mg/dL and above as unhealthy (hyperlipidemia).

| Triglycerides | 6 and 12 months after trial enrollment | Triglycerides, measured in mg/dL. The CDC recommends levels of triglycerides below 150 mg/dL.

The American College of Cardiology identifies normal diastolic blood pressure as below 80 mm Hg and elevated/hypertensive diastolic blood pressure as 80 mm Hg or above. Higher levels of diastolic blood pressure indicate worse outcomes. |
