How SWDI leverages expertise and technology to develop creative, cost-effective solutions in diabetes care

The primary aim of research at Scripps Whittier Diabetes Institute is to develop new programs, explore new medications and create unique solutions to enhance the quality of life for individuals with diabetes through both investigator-initiated and commercially-sponsored clinical research studies.


The research teams at Scripps Whittier Diabetes Institute have focused on conducting community-based participatory research for over 25 years and lead the Community and Collaboration Core for the Clinical Translational Science Award at Scripps Research Translational Institute


Our clinical research team, based on the campus of Scripps Memorial Hospital La Jolla, partners with expert physicians within the Scripps Clinic Medical Group to offer access to the latest studies with medications and technologies to improve care for people with diabetes.  


Investigator-initiated projects

Researcher investigators, physicians, patients, and other stakeholders work closely together at Scripps Whittier Diabetes Institute to invent creative, integrative, and practical solutions to unaddressed issues in diabetes care and management through funding from investigator-initiated research projects. Whittier is at the leading edge of the development of more effective, cost-effective, and pragmatic approaches to improving clinical outcomes in diabetes.


The overarching goal of investigator-initiated research is to improve the quality of and patients’ access to diabetes care by developing new programs and enhancing or adapting existing treatments. 


Cross-cutting project themes are: 


  • Leveraging technology 
  • Using team-based care models 
  • Developing new, creative solutions to long-standing barriers in clinical care that contribute to health disparities in diabetes


Our interdisciplinary research team — including investigators, endocrinologists, psychologists, nurses, diabetes educators and other research staff — has a strong track record of success in obtaining funding for these projects from NIH, donations, pharmaceutical companies and other industry partners. Over the past five years, Scripps Whittier Diabetes Institute has received over $1.5 million annually from NIH alone to fund investigator-initiated research studies.

Current investigator-initiated projects

One in three adults hospitalized in California has diabetes. Poor blood sugar control in the hospital is common and can lead to serious complications for patients and longer lengths of stay. This randomized controlled trial tests a new, dynamic, digitized, team-based approach to hospital glucose management: Cloud-Based Real-Time Glucose Evaluation and Management System (Cyber GEMS). This large-scale study (N = 554) tests Cyber GEMS in the hospital environment in an underserved and understudied, yet high-risk population—predominantly low-income, Hispanic adults with type 2 diabetes. In Cyber GEMS, real-time continuous glucose monitoring (CGM) data is transmitted to a Digital Dashboard to facilitate 24/7, real-time remote monitoring for potentially dangerous hypoglycemic (i.e., severe low blood sugar) episodes. Achieving and maintaining good blood sugar control among hospitalized patients with diabetes is imperative. Cyber GEMS was specifically designed to address this problem, and to improve care quality and clinical outcomes that are highly important to our patients.

More than a third of people with diabetes experience significant diabetes distress, or the understandable emotional burden of managing a demanding chronic condition on a daily basis. Diabetes distress is, in turn, related to poorer diabetes self-care and glucose control. Previously tested interventions for diabetes distress have been effective in reducing emotional overwhelm but not in improving blood glucose levels. This large-scale randomized controlled trial (N = 484) tests a new telemedicine intervention for diabetes distress that uses an Acceptance and Commitment Therapy (ACT) approach — ACT1VATE. This project compares ACT1VATE versus usual care in improving clinical, behavioral, psychosocial, process, and cost outcomes over 12 months among people. It will be tested among adults with type 1 diabetes, who are experiencing significant diabetes distress and poor glycemic control. In line with the American Diabetes Association’s recommendation to address diabetes distress as part of routine diabetes care, this study tests a new approach for supporting our patient’s emotional needs to managing diabetes distress and poor glucose control by enhancing existing systems of care for diabetes in a real-world setting.

Communities of color are at greater risk for developing diabetes and diabetes-related complications and unfortunately, also experience more barriers to accessing health care. Our team previously developed a culturally-tailored diabetes education and digital text messaging program — Project Dulce and Dulce Digital — for the Hispanic population. This suite of research programs will assess the feasibility, acceptability and effectiveness of various modalities for delivering diabetes education programs, i.e., live group, video group or through digital text messaging in Hispanic populations, and will test these methods in other communities at equally high prevalence of diabetes-Filipino and Middle Eastern populations.

Past investigator-initiated projects

Hispanic adults are at greater risk for developing diabetes and diabetes-related complications and unfortunately, also experience more barriers to accessing health care. Our team previously developed a culturally-tailored diabetes education program — Dulce Digital — specifically for this group. This project tests an enhanced version of Dulce Digital in response to previous participants’ requests for a more tailored, personalized version of the treatment. The new program, Dulce Digital-Me, includes Dulce Digital program components (educational text messages and remote-monitoring of blood glucose values) plus personalized goal-setting and feedback to tailor text messaging content to individuals’ behavioral progress and ever-changing context. This large-scale randomized trial includes N = 414 Hispanic adults of low socioeconomic status with poorly controlled type 2 diabetes over a 12-month period. This project will help clarify how technology can be most effectively and efficiently integrated into primary care to reduce diabetes disparities in this high-risk group of Hispanic adults.

Hispanic adults with diabetes are disproportionately affected by COVID-19 — they experience greater rates of infection and are more likely to experience serious illness and mortality due to COVID-19. Good diabetes self-care and day-to-day glucose control are key to reducing these risks, but pandemic-related stay-at-home orders and changes in healthcare protocols have made this more challenging. Supported by a supplement award to Dulce Digital-Me, this randomized controlled trial tests a timely update to our previously developed program, Dulce Digital — a proven-effective combination of “one-size-fits-all” educational text messages and nurse monitoring of patient-transmitted blood glucose values. The new program, Dulce Digital-COVID Aware, incorporates additional education specifically aimed to reduce rates of COVID-19 transmission in high-risk Hispanics with type 2 diabetes during a highly vulnerable period post-discharge from Scripps Mercy Hospital, Chula Vista. Dulce Digital-COVID Aware offers an ideal low-cost and flexible solution to reduce hospital admissions and re-admissions in US/Mexico border communities that are significantly affected by both type 2 diabetes and COVID-19.

Hispanic adults are at particularly high risk of having diabetes plus other troubling conditions, including other cardiometabolic conditions (e.g., heart disease) and mental health concerns (e.g., depression, anxiety). This large-scale randomized controlled trial tests a new program — Mi Puente (My Bridge) — tailored for and designed specifically to reach 560 Hispanic adults with multiple cardiometabolic conditions and behavioral health concern(s). The project will compare the effectiveness of Mi Puente and usual care in reducing these patients’ future hospital admissions and improving their physical health and quality of life. Mi Puente is a team-based, interdisciplinary intervention that helps support patients and caregivers during their transition from a hospitalization at Scripps Mercy Hospital to 30 days post-discharge from the hospital. The program involves inpatient hospital coaching visits, post-discharge support phone calls and volunteer community mentorship. As a low-cost program that uses existing hospital-based resources, Mi Puente has strong potential to improve health disparities for Hispanic adults who often do not receive adequate cardiometabolic and mental health care.

Diabetes education is a core component of standard care for all adults diagnosed with diabetes, yet a huge portion of these patients never actually receive this resource or drop out quickly after starting. This study aimed to transform the standard approach to diabetes education by adding real-time flash glucose monitoring (FGM) to help patients understand the impact of diet, exercise, medication and stress on their glucose levels in real-time. This project tests the effectiveness of this enhanced diabetes education program on glucose control, diabetes self-management behaviors, quality of life and satisfaction with the program. In this single-group pilot study, this web-based diabetes education + FGM program will be provided to 32 adults with type 2 diabetes whose HbA1C is greater than 8%. This project has the potential to transform the current standard models of diabetes care by leveraging increasingly available technology for monitoring glucose values in real time.

Blood glucose can be challenging to manage in the hospital. Part of the challenge is that the standard approach to testing blood glucose in this setting (point-of-care testing) provides an incomplete picture of glucose levels during the day and night for hospitalized patients. This randomized controlled trial examined CGM as tested a new program that provides patients with type 1 and high-risk type 2 diabetes a safer hospitalization by using continuous glucose monitoring (CGM) devices to track their glucose in real-time, like other continuously monitored vital signs (e.g., heart rate, blood pressure). CGM allows a whole team of providers to easily monitor patients' progress, make recommendations, and initiate discussion when recommended blood glucose targets are not met. Incorporating CGM in the hospital setting using a team-based approach has enormous potential to reduce rates of morbidity, mortality and even health care costs that are strongly associated with poorly controlled blood glucose — a difficult problem to solve using the current point-of-care testing approach. Preliminary results of this study showed that patients who participated in this new inpatient CGM program had more healthy glucose levels than patients in usual care (point-of-care testing).

Diabetes requires ongoing, daily efforts on the part of patients to manage. Unfortunately, type 2 diabetes disproportionately impacts people who already experience many additional barriers to daily diabetes self-care, which is perhaps why underserved populations tend not to receive diabetes education — a cornerstone of effective diabetes care. Moreover, a practical barrier to health care systems providing this important part of diabetes treatment is that diabetes education is simply too complex for primary care physicians to address in the context of their typical 15-minute patient visits. This project was a large-scale randomized controlled trial of the real-world effectiveness and sustainability of different approaches to diabetes education in primary care: the medical assistant health-coaching program (MAC) trained health coaches to team up with primary care providers to deliver diabetes education to 600 adults with type 2 diabetes during routine visits at Neighborhood Healthcare and Scripps in San Diego County over a yearlong period. Ongoing, personalized, and diabetes-specific support from health coaches has the potential to drastically improve this diverse group’s ability to manage their diabetes day-to-day — which is challenging enough as is! The outcome analysis for this trial is currently underway.

Hispanic women are more likely to have multiple risk factors for developing type 2 diabetes — in addition to higher rates of gestational diabetes, carrying extra weight and getting insufficient exercise are more common in this historically underserved and disadvantaged group. In this project, we tested a culturally adapted, peer-led education version of the Diabetes Prevention Program (DPP) lifestyle intervention curriculum in two groups of Hispanic women at elevated risk for diabetes: those with a history of gestational diabetes (n = 24; Dulce Mothers program) or with an elevated body mass index (BMI; n = 37; Nuestra Vida program). In addition to examining how this adapted program impacted participants’ physical and mental health and prevented diagnosis of diabetes, this project also evaluated how feasible and acceptable it was viewed by patients. This project provided important information on how and when to best reach Hispanic women to support their health and well-being. The results of this project showed that Dulce Mothers is a low-cost, feasible and acceptable program that can improve Hispanic women’s diet behavior, mental health and body weight.

Hispanic adults are at greater risk for developing diabetes and diabetes-related complications and unfortunately also experience more barriers to accessing health care (e.g., work, caregiving, transportation). Our team previously developed a culturally appropriate diabetes self-management and education program — Project Dulce — specifically for this group, but practical barriers to accessing this program still limit its reach to its most vulnerable members. Our team created a text-message-based adaptation of Project Dulce to address these barriers. The Dulce Digital program included culturally-tailored and health literacy-sensitive educational and supportive text messages combined with patient monitoring and transmission of blood glucose values. We found that the Dulce Digital program led to significantly greater reductions in blood sugar levels (HbA1c) in adults with poorly controlled type 2 diabetes, compared to usual care (Fortmann et al., 2017).

Hispanic women with a history of gestational diabetes during pregnancy are a particularly underserved group with elevated risk for developing type 2 diabetes and heart disease. This was a single-group pilot trial of Dulce Mothers, a Diabetes Prevention Program-adapted lifestyle intervention designed to reduce the risk of type 2 diabetes and cardiovascular disease in low socioeconomic-status Hispanic women with a history of gestational diabetes. Dulce Mothers built on our previously developed program, Project Dulce, by emphasizing bicultural/bilingual peer-delivered group education to increase the relevance and reach of the program to this specific group of at-risk Hispanic women. Eighty-four participants received Dulce Mothers and were followed for six months to evaluate the impact of participating on their health outcomes. This project was an important step in establishing that this innovative version of the Diabetes Prevention Program specifically adapted for Hispanic women with critical health risk factors is effective and feasible for health systems to incorporate into standard models of care. The results of this project showed that the Dulce Mothers program was feasible, acceptable and improved some aspects of diabetes and cardiovascular disease rates among Hispanic women with a history of gestational diabetes.

Diabetes is the seventh leading cause of death of U.S. adults and disproportionately affects certain diverse groups who are unfortunately underserved in traditional health care systems. That is why our team developed Project Dulce — a culturally-sensitive, peer-led diabetes self-management education program specifically adapted and designed to be relevant and reach Mexican American men and women treated for diabetes in federally qualified community health centers in San Diego County. This randomized controlled trial tested the effectiveness of Project Dulce versus usual care delivered to over 200 Mexican-American adults with type 2 diabetes. Results of this trial showed that Project Dulce significantly reduced blood glucose levels and other cardiometabolic outcomes that are so critical to the short- and long-term health for this important and often underserved diverse group.

Commercially-sponsored clinical trials

The Scripps Whittier Diabetes Institute partners with national and international pharmaceutical and device companies to conduct studies that offer opportunities for individuals with type 1 and type 2 diabetes, obesity, and non-alcoholic steatohepatitis that seek new devices and medications to improve their glucose management and to reduce the risk for associated diseases, such as retinopathy, cardiovascular disease and advanced non-alcoholic fatty liver infiltration. 


Examples of trials recently conducted in our center include: 


  • New once-weekly basal insulins alone and in combination with GLP1-receptor agonists (GLP1-RA), which provide better blood sugar control with less weight gain — remarkably, this means injection requirements can drop from 365 times a year to only 52 
  • Longer-term trials evaluating GLP1-RA (such as Ozempic, Rybelsus and Mounjaro) to treat diabetes and obesity and to prevent heart disease
  • Evaluating the efficacy and safety of advanced hybrid closed loop insulin pump systems for type 1 diabetes
  • An investigator-initiated study, in partnership with gastroenterologists at Scripps Clinic, using a fibroscan device to assess patients with type 2 diabetes for non-alcoholic fatty liver infiltration and fibrosis
