Results Summary

What was the research about?

Type 2 diabetes is a long-term health problem that can be hard to manage. Latino patients from low-income households have high rates of diabetes.

In this study, the research team compared two programs adapted to help Latino patients from low-income households manage their diabetes:

  • Diabetes Self-Management Support Empowerment Model, or DSMS. Doctors referred patients to the program. Over six weeks, patients had nine hours of group sessions in English at a hospital. Topics included how to change eating and activity habits, self-monitor their diabetes, and manage stress. Patients also met with a diabetes educator for one-on-one support.
  • Chronic Care Model, or CCM. Doctors and community health workers, or CHWs, referred patients to the program. CHWs are community members trained to teach about health. CHWs led the program at a community health center in English and Spanish. The program helps patients get care, make decisions, coordinate care, and access community resources.

What were the results?

After one year, patients in the two programs didn’t differ in:

  • Knowledge about diabetes.
  • Confidence to manage diabetes.
  • Blood sugar levels.
  • Body mass index, or BMI. BMI is a measure of a person’s body fat based on their height and weight.

Patients in CCM had a greater decrease in depression symptoms than patients in DSMS.

Patients in both programs knew more about diabetes and had higher confidence to manage diabetes, a slight decrease in blood sugar levels, and no change in BMI.

Who was in the study?

The study included 226 pairs of Latino patients with diabetes or prediabetes who were in DSMS or CCM and each patient’s social support person. This person was a life partner, family member, friend, or neighbor. The average patient age was 52, and 73 percent were women. Patients were from low-income households. The programs took place at hospitals and health centers in Albuquerque, New Mexico.

What did the research team do?

The research team surveyed patients at the start of the study and one year later about diabetes knowledge, confidence to manage diabetes, and depression. Support persons completed surveys about their perceptions of the patient’s confidence and depression. The team hired and trained patients with diabetes who were not in the study to ask survey questions, take blood samples, and measure BMI.

Latino patients with diabetes, caregivers, CHWs, and diabetes educators provided input during the study.

What were the limits of the study?

The study didn’t assign patients by chance to a program. As a result, findings may be due to factors other than the programs. Also, at the start of the study, patients in the two programs differed in blood sugar levels and depression symptoms. The research team couldn’t completely account for these differences in the analysis.

Future research could look at reasons why depression symptoms improved in CCM.

How can people use the results?

Health centers that serve Latino patients can use the results when considering ways to help patients manage their diabetes.

Award Type
Health Conditions Health Conditions These are the broad terms we use to categorize our funded research studies; specific diseases or conditions are included within the appropriate larger category. Note: not all of our funded projects focus on a single disease or condition; some touch on multiple diseases or conditions, research methods, or broader health system interventions. Such projects won’t be listed by a primary disease/condition and so won’t appear if you use this filter tool to find them. View Glossary
Populations Populations PCORI is interested in research that seeks to better understand how different clinical and health system options work for different people. These populations are frequently studied in our portfolio or identified as being of interest by our stakeholders. View Glossary
Funding Opportunity Type
Intervention Strategy Intervention Strategies PCORI funds comparative clinical effectiveness research (CER) studies that compare two or more options or approaches to health care, or that compare different ways of delivering or receiving care. View Glossary
