This study evaluates the efficacy and implementation of a telehealth-supported, integrated diabetes group visit program led by Community Health Workers (CHWs). Primary study relates to efficacy and a secondary study addresses mentored implementation.
The number of Hispanics diagnosed with diabetes is escalating in the US with disproportionately higher prevalence and complication rates than other ethnicities. CHWs are a well-established and culturally sensitive means to bridge gaps in care to individuals with diabetes. However CHWs are often left unsupported, placing patients at risk of substandard care or harm. Telehealth is a term used to describe a range of technologies to support healthcare delivery via communication with the patient or a member of the healthcare delivery team. Though telehealth has been implemented into diabetes programs for many years, there is a paucity of data showing the use of telemedicine for CHW training and support.
The primary study (n=89; Cohorts 1,2) compares clinical outcomes and treatment satisfaction of individuals who receive diabetes care in a 12-month telehealth supported, integrated CHW-led group visit program compared to those in usual care (wait list control). Group visits are 6-months and CHWs contact patients weekly to bimonthly (mobile health (mHealth)) for 12-months. This phase with have two cohort waves, separated by 6-months. The wait list control group for Cohort 2 will explore telehealth, clinician-patient encounters. A secondary study (n=59; Cohorts 3,4) at a new clinic evaluates the ability to implement the program. In the first phase of the secondary study the research team will conduct a RCT of individuals randomized to the diabetes program (intervention) vs usual care (control) to assess clinic feasibility. The clinic team will observe this process and learn the project protocols during Phase 1. In the second phase, the clinic team will lead the group visits while the research team mentors them to conduct the project in-person at the group visits and via telehealth each week (ZOOM video conferencing). Another secondary study (n=138; Cohort 5) aims to expand the reach of the education and CHW intervention for individuals who may not be able to or cannot come to the clinic for group visits. Specifically, individuals will received the education from the program monthly via a secure text message video, CHWs will contact weekly to bimonthly to advocate for their needs, and participants will receive their routine care as usual in the clinic.

The survey totaled 12 questions and assessed participant satisfaction, mental relaxation, faith/spirituality, and open-ended comments. Questions were ranked as followed: 1-3 (4-point Likert Scale), 4-7 (10-point Likert Scale), 8-11 (open-ended, descriptive), 12 (days of exercise/week). The Use of Mental Stress Management/Relaxation Techniques questionnaire and our pilot study survey templates were used to evaluate patient group visit and CHW satisfaction. We defined acceptability as high (3.5-4/4 or 8-10/10), moderate (2-3.4/4 or 4-7/10), and low (1-1.9/4 or 1-3/10) and totaled the items to create an overall score. |

| Diabetes-related health | As measured by the Self Management Resource Center Surveys: Diabetes Medications (a 4-question yes/no survey to assess patient medication adherence and understanding of their medications), Self-rated Health (a 1-question ranked on a 5-point scale (1 is excellent, 5 is poor) to determine the patient's view of their health) | at the beginning and end of each cohort (baseline, six-months) |
| Body Mass Index (BMI) | Body Mass Index (BMI) (weight in kg/height in m^2) | At baseline and every 6-month until study completion |

| Feasibility and acceptability of telemedicine support for community health workers | As measured by a six-month 4-question survey (four open-ended questions i.e., what CHWs liked, disliked, general comments) and a 10-question multiple choice posttest that covers content they were taught the last six months (Vaughan et al, 2018) | After each cohort (every six months) |

| CHW knowledge | As measured by pre- /post-tests. TEST-1 (n=21 questions) and TEST-2 (n=19 questions). Tests were multiple choice with 3-5 answer option and were original to this study. | During Cohort 2 at baseline (TEST-1 pretest), 6- (TEST-1 posttest, TEST-2 pretest) and 12-months (TEST-2 posttest) |
| CHW knowledge | This will be accomplished by the 24-question Starr County Diabetes Knowledge Test, which has shown validity and reliability in English and Spanish. Each of the 24-question has three answer choices. This will be pre/posttest format. | During the secondary study, at baseline and 6-months (pre/posttest) |
| Access to care | As measured by the amount of contact participants had with the clinic during the intervention | from baseline to 12-months |
