Scaling Community-Clinical Linkage Models to Address Diabetes and Hypertension Disparities in the Southeast United States
Study Overview
Detailed Description
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Community Health Workers (CHW) treatment group
There will be 81 treatment participants who will receive the Community Health Workers (CHW) intervention.
Once recruited and consented, surveys will be administered and collected at baseline and 6 months in person or by a study coordinator within two weeks of completion of the CHW coaching component of the intervention.
Participants enrolled in the intervention will receive monthly text and phone call reminders.
in addition, multiple sessions will be hosted at varying times/days of the week to accommodate schedules of both working individuals and at-home caretakers.
Finally, small incentives will be provided at each session to encourage ongoing attendance, and a cash raffle prize will be distributed at program completion for individuals who attend all five sessions.
|
Participants will undergo 5 group-based health education sessions on hypertension and diabetes management and provide culturally and linguistically tailored health information and resources There will be 2 one-on-one in-person meetings and up to 7 follow-up calls/meetings to engage in goal-setting activities regarding changes to health behaviors, medication adherence, or other issues related to diabetes prevention as identified jointly by patient and CHW.
Participants will develop with the CHW and receive a copy of their long-term and short-term Participant Action Plan.
Referrals to other services available in the community (i.e.
exercise classes, social services, mental health, tobacco cessation, etc.
|
No Intervention: Control group
There will be 81 control participants who will be offered the health education sessions as a point of service and not for research purposes

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in BP control
Time Frame: Baseline Visit, 6 months visits
|
The primary outcome will be the proportion of eligible patients at a practice site to achieve BP control (130/80 mmHg) six months following the index office visit.
Individuals receiving care during the implementation of the intervention will be more likely achieve BP control six months following the index office visit than individuals receiving care as usual.
The primary outcome of interest is the proportion of patients who achieve BP control.
this will be measured by the treatment participants and providers surveys.

Baseline Visit, 6 months visits

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Hemoglobin A1c (HbA1c)
Time Frame: 6 months
|
Change in HbA1c will be measured in participants of CHW intervention versus the control participants.
Clinical data will be retrieved from EHR.
|
6 months
|
Change in systolic blood pressure (SBP)
Time Frame: 6 months
|
Change in SBP will be measured in participants of CHW intervention versus the control participants.
Clinical data will be retrieved from EHR.
|
6 months
|
Change in diastolic blood pressure (DBP)
Time Frame: 6 months
|
Change in DBP will be measured in participants of CHW intervention versus the control participants.
Clinical data will be retrieved from EHR.
|
6 months
|
Change in body mass index (BMI)
Time Frame: 6 months
|
Change in BMI will be measured in participants of CHW intervention versus the control participants.
Clinical data will be retrieved from EHR.
|
6 months
|
Physicians Attitudes Regarding the Integrated Intervention
Time Frame: Baseline Visit, 6 months
|
Physician attitudes will be primarily assessed with data from brief surveys collected from the participating clinicians.
Survey items with response scales will be designed to capture data on each of the research questions above.
For instance, participants may be asked to respond on a five-point scale (from 1=strongly agree to 5=strongly disagree) to the following statement: "CHWs are helpful tome".
The survey data come from a small sample (n=approximately 10) and are only intended to quantify descriptive information and not for extensive statistical analyses.
The data will be tabulated and summarized descriptively to assess change in attitudes from baseline to 6 months.

Baseline Visit, 6 months

Barriers and Facilitators to Implementation Adoption and Implications for Scalability
Time Frame: Baseline Visit, 6 months visit, 12 month visit
|
At baseline, qualitative interviews of key informants will assess current satisfaction and usage of CHWs and organizational workflows.
At follow-up the interviews will assess barriers and facilitators to the implementation and adoption process of the integrated intervention appropriates, fidelity to the interventions and the solicit recommendations for the replication and scalability of the intervention to other sites.
Satisfaction and outcomes from the partnership and capacity building process will also be assessed.
Audio-recordings and interview transcripts will be stripped of all identifying data.
Using a qualitative approach, interview data will be transcribed and analysis will follow "constant comparison" analytic approach.
Using "thematic" coding, initial set of codes will be created which will be reviewed by the CAB to ensure they are relevant and complete.
The coded transcripts will be analyzed with ATLAS.ti, a qualitative data analysis software.
