Official title: Evaluating the impact of Medicaid Coverage on Diabetic Foot Care in Safety-Net Populations
Funded at University of Southern California · NIH-11366730 · Data updated 2026-11-12
This project looks at how new Medicaid coverage in California affects foot care, ED visits, and outcomes for adults with diabetes in safety-net populations.

Who could benefit from this research
✓Could help
Adults with diabetes enrolled in safety-net health services in California and treated for diabetic foot ulcers.
✕Less likely to help
Patients not relying on safety-net services or not impacted by Medicaid coverage changes may not experience direct benefits.
What this research studies
If you have diabetes and rely on safety-net health services, this study will look at whether expanded Medicaid coverage changes where you get care for diabetic foot ulcers and how well your feet heal. Researchers will combine electronic health records, Medicaid claims, and surveys to see if more coverage means more access to routine podiatry and fewer urgent ED visits. The goal is to understand real-world patterns in care and outcomes so future policies can improve limb-saving care for low-income patients. Participation involves using de-identified data from health records and patient surveys, with privacy safeguards in place.
Why it matters
Potential benefit: If successful, the findings could lead to policies that improve access to routine foot care and reduce amputations among safety-net patients with diabetes.
How similar studies have gone: Previous research has linked insurance coverage to utilization of preventive foot care, but this project investigates coverage changes in a specific safety-net population and its impact on outcomes.
