Diabetes studies

The incidence of type 2 diabetes is increasing globally as the prevalence of obesity increases, and the incidence of type 1 diabetes is also on the rise. Patients are being diagnosed with both types of diabetes at younger ages. Our researchers study the genetics, prevention, treatment, quality of care, and health outcomes of patients with diabetes.

Assessing the Burden of Diabetes by Type in Children, Adolescents and Young Adults (DiCAYA) – Component B (18 to <45 yrs)

The primary goal of the network is to modernize diabetes surveillance efforts to capitalize on large-volume, electronic health record data streams to provide accurate, timely, cost-effective, granular, and representative indicators of diabetes prevalence and incidence. We aim to monitor overall trends and trends within subgroups (e.g., age, sex, diabetes type, and geographic area).

Care of Mental, Physical, and Substance Use Syndromes (COMPASS)

KPSC is one of nine sites throughout the country funded by an Innovation Award from the Centers of Medicare and Medicaid to implement a coordinated care model for depressed patients with cardiovascular disease. We have the following goals for this project: 1. To implement in three stages a multiple condition collaborative care management model in primary care clinics of care systems in states. 2. To demonstrate that this model improves care quality, patient experience and health, provider satisfaction, and total healthcare costs for the Medicare and Medicaid patients with the targeted conditions. 3. To develop role descriptions and training for the two new types of workers required for this model – care managers and care consultants. 4. To identify the costs and payment models needed by care systems to sustain and spread this care model.

Comparison of type 2 diabetes pharmacotherapy regimens using targeted learning

The multi-center study will compare newer classes of drugs with older, lower-cost medications, and take a close look at whether the benefits and harms differ between patients who are at low risk or high risk of developing heart problems. The study will also look at whether benefits and harms differ based on the patient’s age, sex, race or ethnicity, heart and kidney function, or other health problems. The findings will help patients with type 2 diabetes and their doctors make more personalized medication treatment decisions.

Genetics of Beta Cell Failure in Mexican Americans: Phase II (Beta Gene II)

This application is proposed to call back ~400 individuals in our previous cross-sectional BetaGene cohort study (NIDDK 61628) and re-test them for phenotypes. Analysis will be conducted to determine which genes and how they interact with each other to impact the longitudinal changes in beta-cell function and other T2DM related traits.

Impact of Sugary Beverage Taxes on Weight and Health Outcomes after 3-5 Years

This study uses electronic health records to determine the effects of sugary beverage taxes initiated in 4 Northern California cities compared with control cities in Northern and Southern California. Outcomes include weight change trajectories and prevalence of overweight and obesity among children and adults, and incidence of diabetes among adults with prediabetes. Pre-specified sub-analyses include examining differences by race/ethnicity, age groups, and neighborhood socioeconomic status.

Population-based diabetes in youth registry: SEARCH for Diabetes in Youth, Phase 4, California Site

The aims of this study are (1) to ascertain prevalent diabetes cases in calendar year 2017 among youth age <20 years at diagnosis, using cost-efficient approaches that maximize use of information in the electronic health records (EHRs) and administrative databases, (2) to continue to ascertain newly diagnosed (incident 2015-2020) diabetes cases in youth age <20 years, using cost-efficient approaches that maximize use of EHRs and administrative databases, (3) to determine agreement between the etiological classification of diabetes type using biochemical markers and provider assessment; to describe selected clinical characteristics at diagnosis, and to establish an infrastructure that facilitates the development of more detailed ancillary studies by storing biological samples and preserving contact with potential study participants, and (4) To optimize efficiency of SEARCH surveillance activities through targeted Development and Validation (D&V) Projects designed to utilize electronic health data to operationalize each of the three tiers of surveillance to the extent possible.
