Community health centers across the US are seeking to address the growing prevalence of diabetes in adults. The University of Chicago has partnered with the MidWest Clinicians' Network (MWCN) to conduct a research study to train community health center staff and providers to implement and sustain diabetes group visits, also referred to as shared medical appointments, at their health center. The study's aims are to: 1) Develop, conduct, and evaluate a training program for health center staff to implement a diabetes group visit intervention in their health center; 2) Assess the implementation of diabetes group visits in the community health center setting and determine the cost of implementation; 3) Assess the feasibility and cost of implementing a text-messaging intervention in addition to the implementation of diabetes group visits in the CHC setting at one health center and 4) Assess the impact of the diabetes group visits alone and diabetes group visits plus text-messaging on diabetes process measures, patient outcomes, and patient satisfaction compared to control patients from the same health center with six months of follow-up once the six-month group visit program ends.
