Using Peer Support To Aid in PRevention and Treatment in Prediabetes (UPSTART)

This intervention trial has three specific aims: 1) To implement and test the effectiveness of a peer support model to initiate and sustain healthy diabetes-prevention behaviors in a lower-income, diverse population of prediabetes patients across three different care settings (Kaiser Permanente Northern California, the Department of Veterans Affairs, and a Federally Qualified Health Center); 2) To examine the patient, provider, and system-level mediators and moderators of the effectiveness of the peer support model across the three intervention sites; and 3) To examine the cost-effectiveness of the peer support model, and assess other factors related to the barriers and facilitators to adoption and spread, using the Consolidated Framework for Implementation Research.

Health Delivery Systems Center for Diabetes Translational Research Pilot

The aims of this study are to: 1) support two pilot and feasibility studies in each year of the HDS-CDTR renewal; 2) conduct peer review of pilot and feasibility award applications on an annual basis, using the following criteria: overall impact; relevance to diabetes translational research; the promise for leading to an R-level grant submission; relevance to the Center's translational research cores; and support of the health care delivery system in which they are initiated; and 3) leverage the pilot and feasibility awards as a mechanism to support junior investigators in developing robust careers in translational research in diabetes and diabetes prevention.

Health Delivery Systems Center for Diabetes Translational Research

The Health Delivery Systems Center for Diabetes Translational Research (CDTR) supports diabetes translational research through mentoring and supporting junior faculty, and by fostering collaborations between investigators and health care systems. This is a renewal grant to fund the Center for an additional five years. The CDTR is an infrastructure and training grant, and does not directly fund research studies.

The Safety and Effectiveness of Diabetes Quality Metrics in Elderly Patients

Improving health care quality for seniors with complex chronic conditions is a critical issue for health services and health policy research. Widely-used quality metrics for patients with chronic illness put forth by agencies such as HEDIS and CMS are often based on clinical trials evidence of reduced risk for clinical outcomes in younger study populations with fewer comorbidities, and may not be generalizable or appropriate for elderly patients. The primary goal of this study is to compare the effectiveness of meeting standard national quality metrics for diabetes medication adherence for specific medications, and to meeting HbA1c targets, on preventing adverse events, hospitalizations, and ED visits in elderly patients with diabetes.

Delivery Science Rapid Analysis Program II

The purpose of the Delivery Science Rapid Analysis Program is to create a mechanism that will solicit, prioritize and address rapidly-researchable analytic questions with high-value to both TPMG''s quality improvement initiatives and DOR''s research agenda. The Rapid Analysis program will specifically focus on short-term observational data analyses that can be completed within 6 months. The Delivery Science Rapid Analysis Program will provide timely, strategic data for quality improvement efforts at QOS and TPMG, and disseminate its findings widely both within Kaiser and externally.

Diabetes Screening and Care Received by the Mentally Ill in an Integrated System

This observational study will examine the level of fasting plasma glucose (FPG) and A1c testing in patients with severe mental illness, and examine patient-level predictors of testing and FPG/A1c values.

Encouraging Mail Order Pharmacy Use to Improve Outcomes and Reduce Disparities

Previous research has shown that mail order pharmacy use is associated with improved adherence to cardiometabolic medications, and better LDL-C control in new statin users. In addition, mail order use is more common among white patients and those with higher SES. The purpose of this dissemination and implementation study is to conduct a randomized encouragement trial to test the effectiveness of strategies to encourage mail order pharmacy use in the overall population and among groups at risk for disparities in health outcomes, and to see if increased mail order use results in improved adherence and intermediate CVD risk factor outcomes.

Cardiovascular Benefits and Safety of Glucose-Lowering Therapies in Adults with Diabetes

Cardiovascular (CV) events are the most common cause of death among adults with type 2 diabetes. While the benefits and safety of commonly used blood pressure and cholesterol medications are well established, much less is known about the CV benefits and safety of many commonly used therapies to control glucose. In this project, we carefully assess the impact of specific glucose-lowering strategies on CV events (myocardial infarction and stroke) and on mortality, in order to identify whether some glucose-lowering strategies confer more CV benefit or risks than others. To address this important clinical and public health concern, we will test several specific comparative effectiveness hypotheses, in an electronic medical record-linked Health Care Systems Research Network-based registry of over 650,000 adults with diabetes receiving care in 4 large U.S. health care systems.
