Scaling Community-Clinical Linkage Models to Address Diabetes and Hypertension Disparities in the Southeast United States

The study will provide research training, technical assistance, and capacity-building to community and clinical sites in Georgia for implementation of culturally tailored, evidenced-based CHW programs to improve HTN and diabetes management for South Asians. In addition, the use a multi-theoretical framework to test the effectiveness of a CHW-led intervention compared to usual care among South Asian individuals with diabetes and uncontrolled HTN in Atlanta. The primary outcome is blood pressure control, defined as 130/80 mmHg. It is hypothesized that, compared to usual care, individuals receiving the CHW intervention will be 20% more likely to achieve blood pressure control at 6 months.

And to apply RE-AIM and CFIR frameworks to delineate factors influencing appropriateness, fidelity, adoption, and maintenance of the intervention within clinical and community settings to optimize intervention replication.

In addition, this study will serve as a national information and dissemination resource in the adaptation of evidence-based strategies to reduce geographic disparities in HTN and diabetes across Asian American groups.
