Why people with diabetes aren't getting recommended heart- and kidney-protecting medicines

Challenges to Guideline-Recommended Diabetes Care in the United States

NIH-funded research Johns Hopkins University · NIH-11260188

This project will find out why many people with diabetes in the U.S. do not receive recommended medicines like SGLT2 inhibitors, GLP-1 receptor agonists, and newer mineralocorticoid antagonists, and how age, race, neighborhood, and insurance matter.

What this research studies

We will examine medical and insurance records for millions of Americans with diabetes from OptumLabs (~8.1M), Medicare (~3.1M), and Medicaid (~6.2M) to see who receives guideline-recommended tests and medicines. We will also survey about 1,000 physicians and hold three physician focus groups (about 24 participants) to learn what prevents clinicians from ordering recommended monitoring and medications. The team will compare care and health outcomes across ages, races/ethnicities, neighborhoods, and insurance types and study how differences in care relate to differences in hospitalizations and complications. The goal is to identify real-world barriers that could be changed to improve access to effective diabetes treatments.

Who could benefit from this research

Good fit: Adults in the U.S. with type 1 or type 2 diabetes—especially those covered by Medicare, Medicaid, or commercial plans included in the OptumLabs database—are most directly relevant to this project.

Not a fit: People without diabetes or those living outside the United States are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, the work could guide policy and clinical changes to increase access to guideline-recommended diabetes medicines and reduce preventable complications.

How similar studies have performed: Clinical research has already shown these medicines can reduce cardiovascular and kidney complications, but large-scale analyses linking national claims data with physician surveys to explain care gaps are relatively new.
