Texas Tech University Health Sciences Center (TTUHSC) has been awarded a $50,000 grant from the American Medical Association (AMA) Community Health Impact Lab Micro Grants Program to expand hemoglobin A1C testing access across rural West Texas. Led by Dr. Adrian Billings, the initiative integrates rapid diagnostic tools into existing telehealth sites and community health fairs to close critical rural health disparities.
In vast, medically underserved regions like the Big Bend, distance functions as a barrier. Geographic isolation can act as a risk factor for health, turning manageable metabolic conditions into acute emergencies.
In Plain English: The Clinical Takeaway
- The Test: The hemoglobin A1C test is a blood test that shows a person’s average blood glucose (blood sugar) level over the past three months.
- The Bottleneck: Traditional rural pathways require external blood draws and a two-to-three-day wait for lab processing, delaying clinical feedback.
- The Intervention: Point-of-care testing units placed directly into telehealth and community sites deliver immediate results, allowing physicians to give immediate feedback based on the result.
Closing the Diagnostic Gap in Rural West Texas
Prediabetes and type 2 diabetes frequently advance without noticeable symptoms. Over time, high blood sugar from diabetes can lead to serious health problems, including nerve, kidney and heart damage. Early identification can help delay serious health complications.
For patients living in isolated pockets of West Texas—specifically identified regions like Marathon, Fort Davis, Coyanosa, and the Balmorhea Independent School District—obtaining a routine lab draw involves navigating vast distances. According to Adrian Billings, M.D., Ph.D., F. Marie Hall Endowed Chair of Rural Health and associate academic dean for the School of Medicine at TTUHSC at the Permian Basin, rural ZIP codes routinely function as risk factors simply due to a lack of access to healthcare services within a reasonable driving distance.
“The goal of this was to get hemoglobin A1C machines into some of our existing telehealth sites,” Billings stated in a news release regarding the “Medicine on the Move” initiative. “When a telehealth appointment is being done, and the physician wants a hemoglobin A1C, it can be done right then and there. And then the physician can give immediate feedback based on the result.”
Evaluating the Intervention: Traditional Labs vs. Point-of-Care Testing
| Testing Modality | Processing Time | Clinical Workflow Impact |
|---|---|---|
| Traditional Venipuncture Lab Draw | 2 to 3 days | Requires secondary patient contact. |
| Point-of-Care A1C Testing (TTUHSC Initiative) | Immediate | Enables real-time feedback during live telehealth sessions or community fairs. |
By pairing immediate diagnostics with the TTUHSC Institute of Telehealth and Digital Innovation, the program eliminates the friction of secondary appointments. Patients attending mobile health fairs or utilizing remote clinics receive actionable data immediately.
Funding, Governance, and Scalability
The financial backing for this intervention originates from the American Medical Association’s Community Health Impact Lab Micro Grants Program. The AMA designed this funding mechanism specifically to spark physician-driven innovation that delivers practical, measurable improvements in community health. Furthermore, the program explicitly aims to identify ideas that can be expanded or replicated to benefit more patients nationwide.
“Our rural healthcare crisis is larger than any one institution can handle on their own,” Billings noted. “Working together, we can learn from one another to have a greater impact on that rural patient.”
Contraindications & When to Consult a Doctor
Patients exhibiting acute hyperglycemic symptoms should seek medical evaluation.
As healthcare delivery models adapt to geographic constraints, initiatives like the Medicine on the Move program demonstrate how targeted philanthropic grants can dismantle structural barriers. By bringing point-of-care diagnostics directly to rural communities, TTUHSC is bridging the gap between clinical capability and patient access.
