Comparative Effectiveness Study of the Effect of Initiating Real-time Continuous Glucose Monitoring on Progression of Renal Disease in Adults with Type 2 Diabetes

This study is evaluating the impact of initiating continuous glucose monitoring (CGM) in adults with type 2 diabetes on the progression of kidney disease and changes in glycemic control. Difference-in-difference models will be specified to evaluate pre-post changes in eGFR, urinary albumin excretion, and HbA1c.

Implementation study of a new clinical guideline for hypoglycemia prevention

Hypoglycemia in diabetes patients is common, morbid, and costly. A TPMG-funded team (led by Drs. Lisa Gilliam and Richard Grant) worked with clinical stakeholders to develop a new expert consensus Kaiser Permanente Northern California (KPNC) clinical guideline called Hypoglycemia on a Page (HOAP). HOAP guides proactive, protocol-driven hypoglycemia prevention in KPNC members with diabetes and was published in the KPNC clinical library in May 2023, and disseminated for use by KPNC primary care physicians and accountable population managers who provide diabetes care. This 2024 Community Health proposal will evaluate a natural experiment by comparing trends in ED visits and hospitalizations for hypoglycemia before and after HOAP dissemination across KPNC. We hypothesize that implementation of HOAP will be associated with fewer ED visits and hospitalizations for hypoglycemia.

Relaxed Glycemic Control and the Risk of Infections in Older Adults with Type 2 Diabetes

Older adults with poorly controlled type 2 diabetes (T2D) have a higher risk of infection than patients with good glycemic control. However tight glycemic control (e.g., A1C under 7%) in older adults has other risks. In a longitudinal cohort of T2D patients age 65 and older, we will evaluate the incidence of infections when glycemic control is relaxed to levels recommended by current guidelines.

Health Economic Analysis of Automated Insulin Delivery Systems

Safely administering insulin to manage blood glucose is challenging for people with type 1 diabetes (T1D). Artificial pancreas or automated insulin delivery (AID) systems mimic pancreatic function by measuring blood glucose (using real-time continuous glucose monitoring), calculating insulin requirements, and automatically delivering insulin via an insulin pump. This study will determine if AID systems provide good value compared with standard insulin delivery. We will support the external validation of a computer simulation model (Swedish National Diabetes Register T1D model) which will then be used to estimate the long-term cost-effectiveness (from the US health care system and payer perspective) of AID systems compared with standard therapy among T1D patients. This is a collaboration among DOR, University of Michigan, Jaeb Center for Health Research, and University of Oxford.

Quantifying Racial/ethnic Differences in the Relationship Between Glucose Concentrations and Hemoglobin A1c

Physicians rely on hemoglobin A1c (A1C), an integrated measure of glycemia (blood glucose), to make treatment decisions for patients with diabetes. There is evidence that, given comparable glycemia, A1C results in African Americans can be significantly higher than in whites with similar mean glucose. Racial differences in glycosylation (and thus differences in A1c results) could lead to inequities in diabetes diagnosis, performance measures (e.g., HEDIS), treatment (e.g., unnecessary treatment intensification), and hypoglycemia risk. It is unknown how the A1C-glucose relationship varies in other groups, e.g., Latinx or Asians. Further, it is unclear to what extent observed racial differences may be attributable to innate physiologic factors (e.g., sickle cell trait) or socioeconomics for which race may be a surrogate. We propose to collect glucose data from continuous glucose monitoring (CGM) devices and compare them to A1C data to better understand racial biases in the A1C-glucose relationship.

Comparative effectiveness of intermittently scanned continuous glucose monitors among patients with basal-bolus insulin-treated type 2 diabetes

This study will characterize patients selected by their providers for intermittently-scanned, continuous glucose monitor (isCGM) initiation and estimate the effect of isCGM initiation (relative to non-initiators) on clinical outcomes. We hypothesize that 1) among basal-bolus insulin treated, type 2 diabetes patients, those with poorer glycemic control and history of acute metabolic events are more likely selected by physicians for isCGM initiation, and 2) isCGM initiation will result in significant improvement in glycemic control (based on hemoglobin A1c), reduced risk of hypoglycemia and hyperglycemia (both based on emergency department or hospital utilization), compared with non-initiators. This comparative effectiveness research will be based on a difference-in-differences analysis of changes in these outcomes associated with isCGM initiation, compared to a reference group of patients who do not use isCGM (usual care).

Optimizing Medical Decision-Making for Older Patients with Type 2 Diabetes

Medicare-age patients with type 2 diabetes are projected to double in the next 25 years and have high rates of complications and adverse drug events. However, older patients are largely excluded from the major clinical trials of diabetes care. This lack of clinical evidence has led to conflicting and ambiguous recommendations for care. The study will provide new evidence needed to care for these patients. Aim 1: Characterize variation in patient-reported outcomes, patient-provider relationships, and treatment preferences. Aim 2: Determine glycemic control levels associated with the lowest risk of adverse outcomes, including micro- and macrovascular outcomes, hypoglycemia, and death. Aim 3: Develop a risk-based decision support tool for evidence-based, individualized diabetes care for older adults with diabetes.

Preferences, Management and Outcomes in the Oldest Patients with Diabetes

The aim of this study is to develop, pilot and conduct a survey among older diabetes patients (75 years of age or older) or their caregiver surrogates to collect data on: 1) self-management barriers (e.g., poor functional status, financial barriers, inadequate health literacy, depression); 2) treatment preferences (e.g., goals, attitudes regarding de-intensification and intensification, use of insulin, perceived risks and benefits of treatment); and 3) patient-reported outcomes (PROs) not commonly or comprehensively captured in the electronic medical record (e.g., health-related quality of life, falls, urinary incontinence, chronic pain).
