Diabetes care is complex and requires a multidimensional approach, but interventional programs are difficult to initiate in low-income and minority populations. In the proposed study, investigators will mentor local clinics via telehealth to initiate our diabetes program involving telehealth-support, integrated CHWs, medication-access, and diabetes Education into their clinics. Mentoring local clinics to initiate this intervention is a promising strategy to enhance sustainable diabetes care and reduce disparities in vulnerable minority populations.
Diabetes is a major public health problem in Latino(a)s. There are escalating numbers of Latino(a)s diagnosed with diabetes and at disproportionate rates compared to other ethnicities. Numerous interventions have been initiated to improve minority healthcare including diabetes group visits, which have been valuable in improving education and glycemic control. In our group visit investigations, investigators initiated Community Health Workers (CHWs)-local community members who serve as culturally-sensitive patient liaisons to the healthcare system-as part of the multidisciplinary team. Investigators demonstrated that CHWs are vital team members and particularly helpful in identifying medication-access barriers. However, CHWs are frontline workers and often left unsupported and poorly supervised. Investigators used these data to pioneer the combination of four diabetes interventions. This trial showed that individuals randomized to the intervention significantly improved glycemic control, blood pressure and adherence to American Diabetes Association standards compared to usual care. The study also showed that telehealth (mobile health (mHealth) and ZOOM video conferencing) was instrumental in supporting CHWs in their work and enhancing their communication with patients.
The COVID-19 pandemic has highlighted the expansive use of telehealth and its ability to improve healthcare. It has also underscored the pressing need to improve care for low-income minorities. Though diabetes programs are valuable in improving education and clinical outcomes, they are often difficult to initiate in low-income settings. Pragmatic implementation using telehealth to mentor local clinic teams of providers and CHWs is promising to address these barriers. Investigators have pilot data showing the feasibility of telementoring a local clinic to initiate our program that has resulted in improved HbA1c levels but it needs to be tested within a larger sample. In the proposed study investigators will evaluate this approach in a randomized clinical trial (N=320; intervention=160) of low-income, adult Latino(a)s with type 2 diabetes randomized to the diabetes program intervention versus usual care (UC). Our research group will provide telementoring to local clinic teams to initiate our program into their clinics. To evaluate efficacy, investigators will compare the intervention versus UC clinical changes including HbA1c (primary outcome), blood pressure, cholesterol, and body mass index from baseline to 12-months (AIM 1). To compare longitudinal data of study arms, investigators will follow these clinical measures until 36 months (AIM 2). Investigators will also provide program acceptability and evaluation data for participants and clinic teams from baseline to 12-months (AIM 3). Investigators hypothesize that intervention participants will have superior and more sustainable clinical outcomes compared to UC individuals and that the intervention will have high levels of acceptability and evaluation data. Investigators anticipate that the proposed study will provide justification of telementoring to initiate the intervention and strong evidence to improve the longitudinal care of low-income Latino(a)s with diabetes.

|---|---|---|---|
| Intervention | Experimental | Intervention individuals will receive the 12-month diabetes program |

| Usual Care (UC) | Other | We will define UC as usual clinical care, which consists of diabetes management provider encounters (mean quarterly) plus monthly individual appointments with a pharm-Ds or nutritionists as clinically indicated. In addition, clinics offer multiple other individual and group opportunities. |
