Objective: Among patients with diabetes living in the U.S. with newly detected mild or moderate nonproliferative diabetic retinopathy (NPDR) without diabetic macular edema (DME), we aimed to characterize determinants for receiving standards of care and progression to vision-threatening diabetic retinopathy (VTDR) (severe NPDR, proliferative diabetic retinopathy, DME).

Research design and methods: Electronic health records of patients newly detected with NPDR without DME between 2015 and 2023 were analyzed with use of the Epic Cosmos research platform. We characterized the adjusted associations of urban versus rural residence, race and ethnicity (Hispanic, non-Hispanic [NH] White, NH Black, other), and glycemic control (HbA1c <7.0%, 7.0%-8.9%, ≥9%, unavailable) separately with guideline-recommended care (two of three: ophthalmology visit, primary care visit, and measurement of HbA1c, blood pressure, and LDL cholesterol) in the 2 years after diagnosis and with progression to VTDR.

Results: Average (SD) age for the analytic sample (n = 102,919) was 63 (13.5) years, and 51% were female, 59% NH White, and 7% rural residents. Only 40% received guideline-recommended care, and 14% progressed to VTDR (median follow-up 35 months [interquartile range 18-63]). Urban residence was associated with receiving standards of care in both years (risk ratio 1.08 [95% CI 1.05-1.12]) and progression to VTDR (hazard ratio 1.07 [95% CI 0.99-1.15]). Racial and ethnic minority individulas were more likely to progress to VTDR. Individuals with poor or unknown glycemic control were less likely to receive standards of care and more likely to progress to VTDR.

Conclusions: Understanding the management and progression of newly detected NPDR will require disentangling the independent and interdependent contributions of geography, race and ethnicity, and glycemia.

Objective: To evaluate the Ohio Diabetes Quality Improvement Project (QIP) equity aim to reduce the percentage of Non-Hispanic Black (NHB) and Hispanic patients with A1C >9% by ≥20% over 2 years.

Research design and methods: The Ohio Department of Medicaid, Ohio Colleges of Medicine Government Resource Center, Ohio Medicaid managed care plans, and seven medical schools in Ohio formed the Diabetes QIP collaborative using the collective impact model to improve diabetes outcomes and equity in 20 practices across 11 health systems. The quality improvement (QI) strategies included data audit and feedback, peer-to-peer learning, QI coaching/practice facilitation, and subject matter expert consultation through coaching calls, monthly webinars, and annual virtual learning sessions. Electronic health record data were collected for preintervention (2019-2020) and intervention (2020-2022) periods. Assessments of improvements in A1C were based on prevalence of A1C >9% from preintervention, year 1, and year 2 with stratification by race and ethnicity.

Results: The Diabetes QIP included 7,689 (54% female) sociodemographically diverse patients, self-identifying as non-Hispanic White (NHW) (42%), NHB (43%), Hispanic (8%), non-Hispanic Asian (4%), or other (3%). In year 2 compared with baseline, there were decreases in the proportion of patients with A1C >9% among NHW, NHB, and Hispanic patients (NHW from 19% to 12% [37% reduction], NHB 23% to 18% [22% reduction], and Hispanic 29% to 23% [20% reduction]).

Conclusions: The Ohio Diabetes QIP, focused on multisector collaborative approaches, reduced the percentage of patients with A1C >9% by ≥20% among NHW, NHB, and Hispanic populations. Given the persistence of disparities, further equity-focused refinements are warranted to address disparities in diabetes control.

The American Diabetes Association (ADA) "Standards of Care in Diabetes" includes the ADA's current clinical practice recommendations and is intended to provide the components of diabetes care, general treatment goals and guidelines, and tools to evaluate quality of care. Members of the ADA Professional Practice Committee, an interprofessional expert committee, are responsible for updating the Standards of Care annually, or more frequently as warranted. For a detailed description of ADA standards, statements, and reports, as well as the evidence-grading system for ADA's clinical practice recommendations and a full list of Professional Practice Committee members, please refer to Introduction and Methodology.

Objective: To examine the effects of insulin-adjunctive therapy with a sodium-glucose cotransporter 2 (SGLT2) inhibitor and a glucagon receptor antagonist (GRA) on glycemia, insulin use, and ketogenesis during insulinopenia in type 1 diabetes.

Research design and methods: In a randomized, double-blind, placebo-controlled, crossover trial we assessed the effects of adjunctive SGLT2 inhibitor therapy (dapagliflozin 10 mg daily) alone and in combination with the GRA volagidemab (70 mg weekly) in 12 adults with type 1 diabetes. Continuous glucose monitoring, insulin dosing, and insulin withdrawal tests (IWT) for measurement of glucose and ketogenesis during insulinopenia were completed during insulin-only (Baseline), SGLT2 inhibitor, and combination (SGLT2 inhibitor + GRA) therapy periods.

Results: Average glucose and percent time with glucose in range (70-180 mg/dL) improved with combination therapy versus Baseline and SGLT2 inhibitor (131 vs. 150 and 138 mg/dL [P < 0.001 and P = 0.01] and 86% vs. 70% and 78% [P < 0.001 and P = 0.03], respectively) without increased hypoglycemia. Total daily insulin use decreased with combination therapy versus Baseline and SGLT2 inhibitor (0.41 vs. 0.56 and 0.52 units/kg/day [P < 0.001 and P = 0.002]). Peak β-hydroxybutyrate levels during IWT were lower with combination therapy than with SGLT2 inhibitor (2.0 vs. 2.4 mmol/L; P = 0.048) and similar to levels reached during the Baseline testing period (2.1 mmol/L). Participants reported enhanced treatment acceptability and satisfaction with combination therapy.

Conclusions: Glucagon antagonism enhances the therapeutic effects of SGLT2 inhibition in type 1 diabetes. Combination therapy improves glycemic control, reduces insulin dosing, and suggests a strategy to unlock the benefits of SGLT2 inhibitors while mitigating the risk of diabetic ketoacidosis.
