Background Glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) and sodium–glucose cotransporter‐2 inhibitors (SGLT2is) have favorable cardiovascular outcomes compared with dipeptidyl peptidase‐4 inhibitors (DPP4is) and sulfonylureas in adults with type 2 diabetes and high cardiovascular risk. How these benefits vary across lower levels of cardiovascular risk is unknown. Methods We used nationwide claims data to emulate a comparative effectiveness trial and examine the heterogeneity of treatment effects of GLP‐1RAs, SGLT2is, DPP4is, and sulfonylureas on major adverse cardiovascular events (MACEs) among adults with type 2 diabetes and moderate cardiovascular risk (annualized MACE risk 1%–5%, estimated using the annualized claims‐based MACE estimator). Results Among 386 276 included adults with type 2 diabetes, 25.2% had baseline ACME–predicted MACE risk >1% to ≤2% (lower‐risk patients) and 13.3% had ACME–predicted risk >4% to ≤5% (higher‐risk patients). By year 3 of treatment, higher‐risk patients derived greater absolute benefit than lower‐risk patients when treated with GLP‐1RAs versus sulfonylureas (absolute reduction in the estimated rate of MACE of 3.1% in higher‐risk patients and 1.6% in lower‐risk patients), SGLT2is versus sulfonylureas (absolute reduction, 3.9% in higher‐risk patients and 1.3% in lower‐risk patients), and GLP‐1RAs versus DPP4is (absolute reduction, 1.6% in higher‐risk patients and 0.5% in lower‐risk patients). The relative benefits for MACE were also greater in higher‐risk than lower‐risk patients with SGLT2is versus DPP4is (hazard ratio [HR], 0.78 [95% CI, 0.70–0.87] in higher‐risk patients; HR, 0.99 [95% CI, 0.88–1.12] in lower‐risk patients). Conversely, the relative benefits of DPP4is and GLP‐1RAs versus sulfonylureas were greater in lower‐risk patients: HR 0.76 (95% CI, 0.71–0.81) in lower‐risk and HR 0.91 (95% CI, 0.97–0.96) in higher‐risk patients for DPP4is versus sulfonylureas; HR 0.67 (95% CI, 0.58–0.78) in lower‐risk and HR 0.80 (95% CI, 0.70–0.93) in higher‐risk patients for GLP‐1RAs versus sulfonylurea. Benefits of SGLT2is and GLP‐1RAs were comparable across all risk levels. Conclusions Cardiovascular benefits of SGLT2is and GLP‐1RAs exist across all levels of moderate cardiovascular risk, reinforcing the importance of choosing glucose‐lowering therapies that can prevent MACE in all people with type 2 diabetes.

Abstract Context A national assessment of osteoporosis drug therapy (ODT) use can inform the extent of underdiagnosis and undertreatment of osteoporosis. Objective The aim was to describe trends in ODT use by age, sex, fragility fracture, and documented osteoporosis. Methods This was a retrospective analysis of patient-quarter observations for adults aged ≥50 years with commercial or Medicare Advantage health insurance in the OptumLabs Data Warehouse between 2011 and 2022. The primary outcome was the proportion of patient-quarter observations with ODT use stratified by age, sex, fragility fracture, and documented osteoporosis. Cuzick tests were performed to assess trends ODT use. Results Analysis of 166 673 420 patient-quarter observations revealed that over 70% of patients with fragility fractures did not have documented osteoporosis. Among women aged ≥65 years with documented osteoporosis, ODT fill rates increased between 2011 and 2022 from 36.3% to 50.1% for women without fragility fractures (P < .001) and from 30.8% to 43.7% for women with fragility fractures (P < .001). However, ODT fill rates declined (9.2% to 7.4% between 2011 and 2022) for women with fragility fractures and no documented osteoporosis (P = .015). Similar trends were observed among women aged 50-64 years and men. Conclusion ODT use for patients with documented osteoporosis has increased but remains low. Low rates of ODT use for patients with fragility fractures in the absence of documented osteoporosis suggests that underdiagnosis of osteoporosis contributes to underuse of ODTs.

Key Points Sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists were superior to dipeptidyl peptidase-4 inhibitor and sulfonylurea for preventing kidney complications in patients with type 2 diabetes at moderate cardiovascular disease risk. Sodium-glucose cotransporter 2 inhibitor therapy compared favorably with glucagon-like peptide-1 receptor agonists for kidney disease outcomes. Background CKD is a serious diabetes-related complication. While guidelines recommend use of sodium-glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1RA) therapies to mitigate cardiorenal risk in high-risk patients, the benefit of early initiation of these agents relative to other commonly prescribed glucose-lowering agents in patients at lower baseline cardiovascular disease (CVD) risk remains less clear. Methods This retrospective observational study emulated an idealized target trial using claims data from OptumLabs data warehouse to test the comparative association of treatment with a dipeptidyl peptidase-4 inhibitor (DPP-4i), SGLT2i, GLP-1RA, or sulfonylurea (SU) on a primary kidney composite outcome of incident CKD stages 3–5, kidney failure, or need for KRT in patients with type 2 diabetes and moderate CVD risk. A secondary composite outcome included all components of the primary composite outcome plus death. Results A total of 364,714 adults aged 21 years or older initiating treatment with a DPP-4i ( N =78,843), GLP-1RA ( N =42,049), SGLT2i ( N =45,466), or SU ( N =198,356) were identified. Relative to DPP-4i, SGLT2i (hazard ratio [HR], 0.71; 95% confidence interval [CI], 0.67 to 0.74; P < 0.001) and GLP-1RA (HR, 0.87; 95% CI, 0.83 to 0.92; P < 0.001) treatment was superior for the primary composite outcome. Similarly, SGLT2i (HR, 0.69; 95% CI, 0.66 to 0.73) and GLP-1RA (HR, 0.86; 95% CI, 0.82 to 0.91) treatment was associated with risk reductions for the primary outcome relative to SU treatment. When comparing SGLT2i with GLP-1RA therapy, SGLT2is were superior for the primary composite outcome (HR, 0.81; 95% CI, 0.75 to 0.86; P < 0.001). Similar findings were observed for the secondary composite outcome across all comparisons. Conclusions SGLT2is and GLP-1RAs were superior to DPP-4is and SUs for preventing kidney complications in a type 2 diabetes population with moderate baseline CVD risk.

In this emulated comparative effectiveness target trial of glucagon-like peptide 1 (GLP-1) receptor agonist, sodium–glucose cotransporter 2 (SGLT2) inhibitor, dipeptidyl peptidase 4 (DPP-4) inhibitor, and sulfonylurea therapy among adults with type 2 diabetes at moderate cardiovascular disease risk, sulfonylurea use was associated with a significantly higher risk of hypoglycemia requiring emergency department or hospital care than treatment with DPP-4 inhibitors, GLP-1 receptor agonists, or SGLT2 inhibitors. This consideration can guide the choice of glucose-lowering therapy in this highly prevalent patient population, in whom avoidance of hypoglycemia is important, yet among whom the risk of severe hypoglycemia has not been examined previously.

OBJECTIVE This study aimed to assess the need for practice-wide quality improvement to support evidence-based type 2 diabetes screening for women with a history of gestational diabetes mellitus (GDM) receiving primary care. We sought to add the diagnosis of GDM to the problem list of women who did not have it at baseline. RESEARCH DESIGN AND METHODS We identified all women in our practice with a history of GDM diagnosed between 2002 and 2023, quantified the proportion with GDM documented in their problem list, and examined patient- and clinician-level factors associated with having GDM appropriately documented at baseline. RESULTS We identified 203 women with GDM receiving primary care within internal medicine. Of the 203 women, 73 (35.0%) did not have GDM documented in their problem list. Of those without GDM included on the problem list, 52% were overdue for type 2 diabetes screening compared with 41% of those with GDM documented before our intervention. We found race, parity, and previous abnormal glycemic laboratory test results to be highly predictive of whether the history of GDM was on patients’ problem list. Upon completion of our intervention, we successfully achieved a 100% documentation rate for GDM diagnosis for women who previously lacked documentation in their problem list. CONCLUSION This work paves the way for targeted interventions aimed at improving care for women with a history of GDM, including delivery of interventions and education to prevent the onset of an appropriate clinical screening for type 2 diabetes.

OBJECTIVE To determine the relative hazards of acute and chronic diabetes complications among people with diabetes across the U.S. rural-urban continuum. RESEARCH DESIGN AND METHODS This retrospective cohort study used the OptumLabs Data Warehouse, a deidentified data set of U.S. commercial and Medicare Advantage beneficiaries, to follow 2,901,563 adults (age ≥18 years) with diabetes between 1 January 2012 and 31 December 2021. We compared adjusted hazard ratios (HRs) of diabetes complications in remote areas (population &lt;2,500), small towns (population 2,500–50,000), and cities (population &gt;50,000). RESULTS Compared with residents of cities, residents of remote areas had greater hazards of myocardial infarction (HR 1.06 [95% CI 1.02–1.10]) and revascularization (HR 1.04 [1.02–1.06]) but lower hazards of hyperglycemia (HR 0.90 [0.83–0.98]) and stroke (HR 0.91 [0.88–0.95]). Compared with cities, residents of small towns had greater hazards of hyperglycemia (HR 1.06 [1.02–1.10]), hypoglycemia (HR 1.15 [1.12–1.18]), end-stage kidney disease (HR 1.04 [1.03–1.06]), myocardial infarction (HR 1.10 [1.08–1.12]), heart failure (HR 1.05 [1.03–1.06]), amputation (HR 1.05 [1.02–1.09]), other lower-extremity complications (HR 1.02 [1.01–1.03]), and revascularization (HR 1.05 [1.04–1.06]) but a smaller hazard of stroke (HR 0.95 [0.94–0.97]). Compared with small towns, residents of remote areas had lower hazards of hyperglycemia (HR 0.85 [0.78–0.93]), hypoglycemia (HR 0.92 [0.87–0.97]), and heart failure (HR 0.94 [0.91–0.97]). Hazards of retinopathy and atrial fibrillation/flutter did not vary geographically. CONCLUSIONS Adults in small towns are disproportionately impacted by complications of diabetes. Future studies should probe for the reasons underlying these disparities.

AbstractObjectiveTrends in use and continuity of use of diabetes‐specific and non‐diabetes weight‐reducing (WR), weight‐inducing (WI), and weight‐neutral (WN) medications were examined among US adults with diabetes and overweight/obesity.MethodsSerial cross‐sectional data from Medical Expenditure Panel Surveys (2010–2019) for adults (≥18 years) with diabetes and BMI ≥27 kg/m2 (≥25 kg/m2 for Asians) were analyzed.ResultsAmong 7402 US adults with diabetes and overweight/obesity (mean age 60.0 years [SD 13], 50% female), 64.9% of participants used any WI medications, decreasing from 68.9% (95% CI: 64.3%–73.5%) in 2010 to 58.6% (95% CI: 54.7%–62.5%) in 2019. It was estimated that 13.5% used WR medications, increasing 3.31‐fold, from 6.4% (95% CI: 4.1%–8.7%) to 21.2% (95% CI: 18.0%–24.4%) and that 73.1% used WN medications, ranging from 70.5% (95% CI: 66.5–74.6) to 75.0% (95% CI: 71.7%–78.4%). Among adults using diabetes‐specific WI (53.7%), WR (7.1%), and WN (62.4%) medications during the first year, 7.3%, 16.4%, and 9.0% discontinued it in the second year, respectively.ConclusionsOver 2010–2019, 64.9% of adults with diabetes and overweight/obesity were treated with WI medications, 13.5% with WR medications, and 73.1% with WN medications. Discontinuation of WR medications was nearly twice that of WI medications.

A rigorous evaluation of the implementation of a diabetes quality measure implementation program across community healthcare clinics in Shanghai, China, where both quality measurement and primary care delivery are relatively recent but centrally supported, identified important concerns about the meaningfulness, feasibility, and accuracy of quality measures that are relevant to all quality measurement programs. These include the importance of stakeholder involvement in measure development and implementation, the need to select measures that accurately and reliably reflect care quality, the link between incentives for improved performance and data manipulation, the necessity for scientific credibility and practical feasibility of the measure, and the assurance that measure performance can be impacted by those being evaluated. In addition to elaborating on these aspects of quality measurement, we also discuss the need for quality measures that are balanced across established domains of quality, are not burdensome to participants, and are transparent, parsimonious, nimble, and oriented around continuous evaluation and improvement.
